Visual Studio compiles WPF application twice during build

- by Brian Ensink

I have a WPF app in VS2008 that compiles twice during the build. The two CSC command lines are similar but with some differences. The first CSC command line does not have an /resource options, the second has two /resource options on the command line. The second CSC command line has these additional arguments: /resource:"obj\Debug AutoCAD\VisualApp.g.resources" /resource:"obj\Debug AutoCAD\CAP.Visual.Properties.Resources.resources" I hate to post such a huge ugly compiler output but here are both command lines. 2>c:\WINDOWS\Microsoft.NET\Framework\v3.5\Csc.exe /noconfig /nowarn:1701,1702 /platform:x86 /errorreport:prompt /warn:4

Using times on the Android platform.

- by Tarmon

Hey Everyone, I have a lot of time information in the format of hh:mm and I was wondering if there is a good way to take this information and compare it to the current time. Say I have a list of times for a day and I want to find out which time in this array of strings is the first that has not already past in this day. I was looking at the Calender API and I figured I could break the strings up into hours and minutes by splitting it at the ":" and then create a calender object from that but that seems rather inefficient. Just looking for some input; thanks, Rob <string-array name="example"> <item>6:58</item> <item>7:41</item> <item>8:08</item> <item>8:28</item> <item>8:48</item> <item>9:08</item> <item>9:43</item> <item>10:13</item> <item>10:43</item> <item>11:13</item> <item>11:43</item> <item>12:09</item> <item>12:29</item> <item>12:49</item> <item>1:09</item> <item>1:29</item> <item>1:49</item> <item>2:09</item> <item>2:29</item> <item>2:49</item> <item>3:09</item> <item>3:29</item> <item>3:49</item> <item>4:09</item> <item>4:29</item> <item>4:49</item> <item>5:09</item> <item>5:29</item> <item>5:49</item> <item>6:29</item> <item>7:09</item> <item>7:47</item> <item>8:27</item> <item>9:07</item> <item>9:47</item> <item>10:27</item> </string-array>

Sharepoint (active directory account creation mode) - Using STSADM

- by vivek m

This question is regarding using STSADM command to create new site collection in Active Directory Account creation mode. My setup is like this- I have 2 virtual PCs in a Windows XP Pro SP3 host. Both VPCs are Windows Server 2003 R2. One VPC acts as the DC, DNS Server, DHCP server, has Active Directory installed and is also the Database Server. The other VPC is the domain member and it is the IIS web server, POP/SMTP server and it has WSS 3.0 installed. I created a new site using the GUI in Central Admin page. For creating a site collection under the newly created site, I needed to use the STSADM command line tool since it cannot be done from Central Admin page in Active Directory Account creation mode. Thats where i got into a problem- stsadm.exe -o createsite -url http://vivek-c5ba48dca:1111/sites/Sales -owneremail [email protected] -sitetemplate STS#1 The format of the specified domain name is invalid.

For some reason for a low-number of users (say 1 in a few hundred) the application seem to crash when run in 64bit mode on a Snow Leopard 10.6.3 I've attached the code, but please remind IT IS NOT A CODE issue.

Any suggestions other then running the application in 32 bit only? Please do not dilute the feedback by asking for or blaming the code, the code is 100% solid, guaranteed! No memory leaks, the crashes clearly are triggered in 32 bit mode only just after start inside the AppKit itself like deep inside NSThread sleep's callstack.

NSArray in NSArray do not return the image I want

- by Tibi

Hi there, I've got a code snippet here that I can't make working. NSUInteger i; //NSMutableArray *textures = [[NSMutableArray alloc] initWithCapacity:kNumTextures]; //NSMutableArray *texturesHighlighted = [[NSMutableArray alloc] initWithCapacity:kNumTextures]; NSMutableArray *textures= [[NSMutableArray alloc] init]; for (i = 1; i <= kNumTextures; i++) { NSString *imageName = [NSString stringWithFormat:@"texture%d.png", i]; NSString *imageNameHighlighted = [NSString stringWithFormat:@"texture%d_select.png", i]; UIImage *image = [UIImage imageNamed:imageName]; UIImage *imageHighlighted = [UIImage imageNamed:imageNameHighlighted]; //NSArray *pics = [[NSArray alloc] initWithObjects:(UIImage)image,(UIImage)imageHighlighted,nil]; NSArray *pics = [NSArray arrayWithObjects:image,imageHighlighted,nil]; [textures addObject:pics]; [pics release]; } //select randomly the position of the picture that will be represented twice on the board NSInteger randomTexture = arc4random()%([textures count]+1); //extract image corresponding to the randomly selected index //remove corresponding pictures from textures array NSArray *coupleTexture = [textures objectAtIndex:randomTexture]; [textures removeObjectAtIndex:randomTexture]; //create the image array containing 1 couple + all other pictures NSMutableArray *texturesBoard = [[NSMutableArray alloc] initWithCapacity:kNumPotatoes]; [texturesBoard addObject:coupleTexture]; [texturesBoard addObject:coupleTexture]; [coupleTexture release]; NSArray *pics = [[NSArray alloc] init]; for (pics in textures) { [texturesBoard addObject:pics]; } [pics release]; //shuffle the textures //[texturesBoard shuffledMutableArray]; //Array with masks NSMutableArray *masks= [[NSMutableArray alloc] init]; for (i = 1; i <= kNumMasks; i++) { NSString *maskName = [NSString stringWithFormat:@"mask%d.png", i]; UIImage *mask = [UIImage imageNamed:maskName]; //NSArray *pics = [[NSArray alloc] initWithObjects:mask,nil]; [masks addObject:mask]; //[pics release]; [maskName release]; [mask release]; } //Now mask all images in texturesBoard NSMutableArray *list = [[NSMutableArray alloc] init]; for (i = 0; i <= kNumMasks-1; i++) { //take on image couple from textures NSArray *imgArray = [texturesBoard objectAtIndex:i]; UIImage *mask = [masks objectAtIndex:i]; //mask it with the mask un the array at corresponding index UIImage *img1 =(UIImage *) [imgArray objectAtIndex:0]; UIImage *img2 =(UIImage *) [imgArray objectAtIndex:1]; UIImage *picsMasked = [self maskImage:(UIImage *)img1 withMask:(UIImage *)mask]; UIImage *picsHighlightedMasked = [self maskImage:(UIImage *)img2 withMask:(UIImage *)mask]; //Init image with highlighted status TapDetectingImageView *imageView = [[TapDetectingImageView alloc] initWithImage:picsMasked imageHighlighted:picsHighlightedMasked]; [list addObject:imageView]; } The problem here is that : img1 and img2, are not images but rather NSArray with multiple entries. Ican't figure why... dos any fresh spirit here could provide me with some clue to fix. maaany thanks.

JSON Formatting with Jersey, Jackson, & json.org/java Parser using Curl Command

- by socal_javaguy

Using Java 6, Tomcat 7, Jersey 1.15, Jackson 2.0.6 (from FasterXml maven repo), & www.json.org parser, I am trying to pretty print the JSON String so it will look indented by the curl -X GET command line. I created a simple web service which has the following architecture: My POJOs (model classes): Family.java import javax.xml.bind.annotation.XmlRootElement; @XmlRootElement public class Family { private String father; private String mother; private List<Children> children; // Getter & Setters } Children.java import javax.xml.bind.annotation.XmlRootElement; @XmlRootElement public class Children { private String name; private String age; private String gender; // Getters & Setters } Using a Utility Class, I decided to hard code the POJOs as follows: public class FamilyUtil { public static Family getFamily() { Family family = new Family(); family.setFather("Joe"); family.setMother("Jennifer"); Children child = new Children(); child.setName("Jimmy"); child.setAge("12"); child.setGender("male"); List<Children> children = new ArrayList<Children>(); children.add(child); family.setChildren(children); return family; } } My web service: import java.io.IOException; import javax.ws.rs.GET; import javax.ws.rs.Path; import javax.ws.rs.PathParam; import javax.ws.rs.Produces; import javax.ws.rs.core.MediaType; import org.codehaus.jackson.JsonGenerationException; import org.codehaus.jackson.map.JsonMappingException; import org.codehaus.jackson.map.ObjectMapper; import org.codehaus.jettison.json.JSONException; import org.json.JSONObject; import org.json.JSONTokener; import com.myapp.controller.myappController; import com.myapp.resource.output.HostingSegmentOutput; import com.myapp.util.FamilyUtil; @Path("") public class MyWebService { @GET @Produces(MediaType.APPLICATION_JSON) public static String getFamily() throws IOException, JsonGenerationException, JsonMappingException, JSONException, org.json.JSONException { ObjectMapper mapper = new ObjectMapper(); String uglyJsonString = mapper.writeValueAsString(FamilyUtil.getFamily()); System.out.println(uglyJsonString); JSONTokener tokener = new JSONTokener(uglyJsonString); JSONObject finalResult = new JSONObject(tokener); return finalResult.toString(4); } } When I run this using: curl -X GET http://localhost:8080/mywebservice I get this in my Eclipse's console: {"father":"Joe","mother":"Jennifer","children":[{"name":"Jimmy","age":"12","gender":"male"}]} But from the curl command on the command line (this response is more important): "{\n \"mother\": \"Jennifer\",\n \"children\": [{\n \"age\": \"12\",\n \"name\": \"Jimmy\",\n \"gender\": \"male\"\n }],\n \"father\": \"Joe\"\n}" This is adding newline escape sequences and placing double quotes (but not indenting like it should it does have 4 spaces after the new line but its all in one line). Would appreciate it if someone could point me in the right direction.

OpenGL-ES Texture Mapping. Texture is reversed?

- by Feet

I am trying to get my head around Texture mapping, I thought I had it the other day after asking this. However, I am having some trouble with my texture coordinates being flipped from what I am expecting. I am loading my texture like so int[] textures = new int[1]; gl.glGenTextures(1, textures, 0); _textureID = textures[0]; gl.glBindTexture(GL10.GL_TEXTURE_2D, _textureID); Bitmap bmp = BitmapFactory.decodeResource( _context.getResources(), R.drawable.die_1); GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, bmp, 0); gl.glTexParameterx(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_LINEAR); gl.glTexParameterx(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR); bmp.recycle(); My cube is this float vertices[] = { // Front face -width, -height, depth, // 0 width, -height, depth, // 1 width, height, depth, // 2 -width, height, depth, // 3 // Back Face width, -height, -depth, // 4 -width, -height, -depth, // 5 -width, height, -depth, // 6 width, height, -depth, // 7 // Left face -width, -height, -depth, // 8 -width, -height, depth, // 9 -width, height, depth, // 10 -width, height, -depth, // 11 // Right face width, -height, depth, // 12 width, -height, -depth, // 13 width, height, -depth, // 14 width, height, depth, // 15 // Top face -width, height, depth, // 16 width, height, depth, // 17 width, height, -depth, // 18 -width, height, -depth, // 19 // Bottom face -width, -height, -depth, // 20 width, -height, -depth, // 21 width, -height, depth, // 22 -width, -height, depth, // 23 }; short indices[] = { // Front 0,1,2, 0,2,3, // Back 4,5,6, 4,6,7, // Left 8,9,10, 8,10,11, // Right 12,13,14, 12,14,15, // Top 16,17,18, 16,18,19, // Bottom 20,21,22, 20,22,23, }; float texCoords[] = { // Front face textured only, for simplicity 0.0f, 1.0f, 1.0f, 1.0f, 0.0f, 0.0f, 1.0f, 0.0f}; And it is drawn like so // Counter-clockwise winding. gl.glFrontFace(GL10.GL_CCW); // Enable face culling. gl.glEnable(GL10.GL_CULL_FACE); // What faces to remove with the face culling. gl.glCullFace(GL10.GL_BACK); // Enabled the vertices buffer for writing and to be used during // rendering. gl.glEnableClientState(GL10.GL_VERTEX_ARRAY); // Specifies the location and data format of an array of vertex // coordinates to use when rendering. gl.glVertexPointer(3, GL10.GL_FLOAT, 0, verticesBuffer); if (normalsBuffer != null) { // Enabled the normal buffer for writing and to be used during rendering. gl.glEnableClientState(GL10.GL_NORMAL_ARRAY); // Specifies the location and data format of an array of normals to use when rendering. gl.glNormalPointer(GL10.GL_FLOAT, 0, normalsBuffer); } // Set flat color gl.glColor4f(rgba[0], rgba[1], rgba[2], rgba[3]); // Smooth color if ( colorBuffer != null ) { // Enable the color array buffer to be used during rendering. gl.glEnableClientState(GL10.GL_COLOR_ARRAY); // Point out the where the color buffer is. gl.glColorPointer(4, GL10.GL_FLOAT, 0, colorBuffer); } // Use textures? if ( textureBuffer != null) { gl.glEnableClientState(GL10.GL_TEXTURE_COORD_ARRAY); gl.glEnable(GL10.GL_TEXTURE_2D); gl.glTexCoordPointer(2, GL10.GL_FLOAT, 0, textureBuffer); } // Translation and rotation before drawing gl.glTranslatef(x, y, z); gl.glRotatef(rx, 1, 0, 0); gl.glRotatef(ry, 0, 1, 0); gl.glRotatef(rz, 0, 0, 1); gl.glDrawElements(GL10.GL_TRIANGLES, numOfIndices, GL10.GL_UNSIGNED_SHORT, indicesBuffer); // Disable the vertices buffer. gl.glDisableClientState(GL10.GL_VERTEX_ARRAY); gl.glDisableClientState(GL10.GL_COLOR_ARRAY); gl.glDisableClientState(GL10.GL_NORMAL_ARRAY); gl.glDisableClientState(GL10.GL_TEXTURE_COORD_ARRAY); // Disable face culling. gl.glDisable(GL10.GL_CULL_FACE); However my front face looks like this I also add, I haven't got any normals set, are textures affected by normals? float texCoords[] = { // Front 1.0f, 1.0f, 0.0f, 1.0f, 0.0f, 0.0f, 1.0f, 0.0f} It seems as if the texture is being flipped, so the coordinates don't match up properly?

iphone app: delegate not responding

- by Fiona

Hi guys.. So i'm very new to this iphone development stuff.... and i'm stuck. I'm building an app that connects to the twitter api. However when the connectionDidFinishLoading method gets called, it doesn't seem to recognise the delegate. Here's the source code of the request class: import "OnePageRequest.h" @implementation OnePageRequest @synthesize username; @synthesize password; @synthesize receivedData; @synthesize delegate; @synthesize callback; @synthesize errorCallBack; @synthesize contactsArray; -(void)friends_timeline:(id)requestDelegate requestSelector:(SEL)requestSelector{ //set the delegate and selector self.delegate = requestDelegate; self.callback = requestSelector; //Set up the URL of the request to send to twitter!! NSURL *url = [NSURL URLWithString:@"http://twitter.com/statuses/friends_timeline.xml"]; [self request:url]; } -(void)request:(NSURL *) url{ theRequest = [[NSMutableURLRequest alloc] initWithURL:url]; theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; if (theConnection){ //Create the MSMutableData that will hold the received data. //receivedData is declared as a method instance elsewhere receivedData=[[NSMutableData data] retain]; }else{ //errorMessage.text = @"Error connecting to twitter!!"; } } -(void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge{ if ([challenge previousFailureCount] == 0){ NSLog(@"username: %@ ",[self username]); NSLog(@"password: %@ ",[self password]); NSURLCredential *newCredential = [NSURLCredential credentialWithUser:[self username] password:[self password] persistence:NSURLCredentialPersistenceNone]; [[challenge sender] useCredential:newCredential forAuthenticationChallenge:challenge]; } else { [[challenge sender] cancelAuthenticationChallenge:challenge]; NSLog(@"Invalid Username or password!"); } } -(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response{ [receivedData setLength:0]; } -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{ [receivedData appendData:data]; } -(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error{ [theConnection release]; [receivedData release]; [theRequest release]; NSLog(@"Connection failed. Error: %@ %@", [error localizedDescription], [[error userInfo] objectForKey:NSErrorFailingURLStringKey]); if(errorCallBack){ [delegate performSelector:errorCallBack withObject:error]; } } -(void)connectionDidFinishLoading:(NSURLConnection *)connection{ if (delegate && callback){ if([delegate respondsToSelector:[self callback]]){ [delegate performSelector:[self callback] withObject:receivedData]; }else{ NSLog(@"No response from delegate!"); } } [theConnection release]; [theRequest release]; [receivedData release]; } Here's the .h: @interface OnePageRequest : NSObject { NSString *username; NSString *password; NSMutableData *receivedData; NSURLRequest *theRequest; NSURLConnection *theConnection; id delegate; SEL callback; SEL errorCallBack; NSMutableArray *contactsArray; } @property (nonatomic,retain) NSString *username; @property (nonatomic,retain) NSString *password; @property (nonatomic,retain) NSMutableData *receivedData; @property (nonatomic,retain) id delegate; @property (nonatomic) SEL callback; @property (nonatomic) SEL errorCallBack; @property (nonatomic,retain) NSMutableArray *contactsArray; -(void)friends_timeline:(id)requestDelegate requestSelector:(SEL)requestSelector; -(void)request:(NSURL *) url; @end In the method: connectionDidFinishLoading, the following never gets executed: [delegate performSelector:[self callback] withObject:receivedData]; Instead I get the message: "No response from delegate" Anyone see what I'm doing wrong?! or what might be causing the problem?

Unable to use NSURLConnection to get contents of password/username protected webpage

- by bubster

I am trying to get the contents of a webpage that requires a password and user name to access. I am using a NSURLConnection object to get it however when I write the NSMutableData object that is returned to a file all I get is the login page. Normally when you try to load the password protected page when you are not logged in it redirects to the login page however I thought that if I provided valid credentials then this I would be able to view the password protected page. Also I do not know if it is relevant the website is using a microsoft mysql database on an IIS (internet information server). Note: [protectionSpace authenticationMethod] returns NSURLAuthenticationMethodServerTrust I am pretty unfamiliar with this so any ideas would be greatly appreciated. Below is all of the relevant code: - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { // This method is called when the server has determined that it // has enough information to create the NSURLResponse. // It can be called multiple times, for example in the case of a // redirect, so each time we reset the data. // receivedData is an instance variable declared elsewhere. [receivedData setLength:0]; } - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { // Append the new data to receivedData. // receivedData is an instance variable declared elsewhere. [receivedData appendData:data]; } - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { // release the connection, and the data object //[connection release]; // receivedData is declared as a method instance elsewhere //[receivedData release]; // inform the user NSLog(@"Connection failed! Error - %@ %@", [error localizedDescription], [[error userInfo] objectForKey:NSURLErrorFailingURLStringErrorKey]); } - (void)connectionDidFinishLoading:(NSURLConnection *)connection { // do something with the data // receivedData is declared as a method instance elsewhere NSLog(@"Succeeded! Received %d bytes of data",[receivedData length]); // release the connection, and the data object //[connection release]; //[receivedData release]; //Write data to a file [receivedData writeToFile:@"/Users/matsallen/Desktop/receivedData.html" atomically:YES]; } - (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace: (NSURLProtectionSpace *)protectionSpace { NSLog(@"The connection encountered a protection space. The authentication method is %@", [protectionSpace authenticationMethod]); secureTrustReference = [protectionSpace serverTrust]; //SecTrustResultType *result; //OSStatus status = SecTrustEvaluate(secureTrustReference, result); //NSLog(@"Result of the trust evaluation is %@",status); return YES; } - (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge { NSURLCredential *newCredential; newCredential = [NSURLCredential credentialWithUser:@"username" password:@"password" persistence:NSURLCredentialPersistenceForSession]; newCredential = [NSURLCredential credentialForTrust:secureTrustReference]; // [[challenge sender] useCredential:newCredential forAuthenticationChallenge:challenge]; // [[challenge sender] continueWithoutCredentialForAuthenticationChallenge:challenge]; } #pragma mark - View lifecycle - (void)viewDidLoad { receivedData = [[NSMutableData alloc] init]; [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. // Create the request. NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:@"https://www.markallenonline.com/secure/maoCoaching.aspx"] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; // create the connection with the request // and start loading the data NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; if (theConnection) { // Create the NSMutableData to hold the received data. // receivedData is an instance variable declared elsewhere. receivedData = [NSMutableData data]; NSLog(@"Connection succeeded!"); } else { // Inform the user that the connection failed.

C++/msvc6 application crashes due to heap corruption, any hints?

- by David Alfonso

Hello all, let me say first that I'm writing this question after months of trying to find out the root of a crash happening in our application. I'll try to detail as much as possible what I've already found out about it. About the application It runs on Windows XP Professional SP2. It's built with Microsoft Visual C++ 6.0 with Service Pack 6. It's MFC based. It uses several external dlls (e.g. Xerces, ZLib or ACE). It has high performance requirements. It does a lot of network and hard disk I/O, but it's also cpu intensive. It has an exception handling mechanism which generates a minidump when an unhandled exception occurs. Facts about the crash It only happens on multiprocessor/multicore machines and under heavy loads of work. It happens at random (neither we nor our client have found a pattern yet). We cannot reproduce the crash on our testing lab. It only happens on some production systems (but always in multicore machines) It always ends up crashing at the same point, although the complete stack is not always the same. Let me add the stack of the crashing thread (obtained using WinDbg, sorry we don't have symbols) ChildEBP RetAddr Args to Child WARNING: Stack unwind information not available. Following frames may be wrong. 030af6c8 7c9206eb 77bfc3c9 01a80000 00224bc3 MyApplication+0x2a85b9 030af960 7c91e9c0 7c92901b 00000ab4 00000000 ntdll!RtlAllocateHeap+0xeac (FPO: [Non-Fpo]) 030af98c 7c9205c8 00000001 00000000 00000000 ntdll!ZwWaitForSingleObject+0xc (FPO: [3,0,0]) 030af9c0 7c920551 01a80898 7c92056d 313adfb0 ntdll!RtlpFreeToHeapLookaside+0x22 (FPO: [2,0,4]) 030afa8c 4ba3ae96 000307da 00130005 00040012 ntdll!RtlFreeHeap+0x1e9 (FPO: [Non-Fpo]) 030afacc 77bfc2e3 0214e384 3087c8d8 02151030 0x4ba3ae96 030afb00 7c91e306 7c80bfc1 00000948 00000001 msvcrt!free+0xc8 (FPO: [Non-Fpo]) 030afb20 0042965b 030afcc0 0214d780 02151218 ntdll!ZwReleaseSemaphore+0xc (FPO: [3,0,0]) 030afb7c 7c9206eb 02e6c471 02ea0000 00000008 MyApplication+0x2965b 030afe60 7c9205c8 02151248 030aff38 7c920551 ntdll!RtlAllocateHeap+0xeac (FPO: [Non-Fpo]) 030afe74 7c92056d 0210bfb8 02151250 02151250 ntdll!RtlpFreeToHeapLookaside+0x22 (FPO: [2,0,4]) 030aff38 77bfc2de 01a80000 00000000 77bfc2e3 ntdll!RtlFreeHeap+0x647 (FPO: [Non-Fpo]) 7c92056d c5ffffff ce7c94be ff7c94be 00ffffff msvcrt!free+0xc3 (FPO: [Non-Fpo]) 7c920575 ff7c94be 00ffffff 12000000 907c94be 0xc5ffffff 7c920579 00ffffff 12000000 907c94be 90909090 0xff7c94be *** WARNING: Unable to verify checksum for xerces-c_2_7.dll *** ERROR: Symbol file could not be found.

What I have tried so far Reviewing all the code related to the point where the crash ends happening. Trying to enable pageheap on our testing lab though nothing useful has been found by now. We have substituted the std::list for a C array and then it crashes in other part of the code (although it is related code, it's not in the code where the old list resided). Coincidentally, now it crashes in another erase, though this time of a std::multiset. Let me copy the stack contained in the dump: ntdll.dll!_RtlpCoalesceFreeBlocks@16() + 0x124e bytes ntdll.dll!_RtlFreeHeap@12() + 0x91f bytes msvcrt.dll!_free() + 0xc3 bytes MyApplication.exe!006a4fda() [Frames below may be incorrect and/or missing, no symbols loaded for MyApplication.exe] MyApplication.exe!0069f305() ntdll.dll!_NtFreeVirtualMemory@16() + 0xc bytes ntdll.dll!_RtlpSecMemFreeVirtualMemory@16() + 0x1b bytes ntdll.dll!_ZwWaitForSingleObject@12() + 0xc bytes ntdll.dll!_RtlpFreeToHeapLookaside@8() + 0x26 bytes ntdll.dll!_RtlFreeHeap@12() + 0x114 bytes msvcrt.dll!_free() + 0xc3 bytes c5ffffff() Possible solutions (that I'm aware of) which cannot be applied "Migrate the application to a newer compiler": We are working on this but It's not a solution at the moment. "Enable pageheap (normal or full)": We can't enable pageheap on production machines as this affects performance heavily. I think that's all I remember now, if I have forgotten something I'll add it asap. If you can give me some hint or propose some possible solution, don't hesitate to answer! Thank you in advance for your time and advice.

WebClient.DownloadDataAsync is freezing my UI

- by Matías

Hi, I have in my Form constructor, after the InitializeComponent the following code: using (WebClient client = new WebClient()) { client.DownloadDataCompleted += new DownloadDataCompletedEventHandler(client_DownloadDataCompleted); client.DownloadDataAsync("http://example.com/version.txt"); } When I start my form, the UI doesn't appears till client_DownloadDataCompleted is raised. The client_DownloadDataCompleted method is empty, so there's no problem there. What I'm doing wrong? How is supposed to do this without freezing the UI? Thanks for your time. Best regards. FULL CODE: Program.cs using System; using System.Windows.Forms; namespace Lala { static class Program { /// <summary> /// The main entry point for the application. /// </summary> [STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new Form1()); } } } Form1.cs using System; using System.Net; using System.Windows.Forms; namespace Lala { public partial class Form1 : Form { WebClient client = new WebClient(); public Form1() { client.DownloadDataCompleted += new DownloadDataCompletedEventHandler(client_DownloadDataCompleted); client.DownloadDataAsync(new Uri("http://www.google.com")); InitializeComponent(); } void client_DownloadDataCompleted(object sender, DownloadDataCompletedEventArgs e) { textBox1.Text += "A"; } } partial class Form1 { /// <summary> /// Required designer variable. /// </summary> private System.ComponentModel.IContainer components = null; /// <summary> /// Clean up any resources being used. /// </summary> /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param> protected override void Dispose(bool disposing) { if (disposing && (components != null)) { components.Dispose(); } base.Dispose(disposing); } #region Windows Form Designer generated code /// <summary> /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// </summary> private void InitializeComponent() { this.button1 = new System.Windows.Forms.Button(); this.textBox1 = new System.Windows.Forms.TextBox(); this.SuspendLayout(); // // button1 // this.button1.Location = new System.Drawing.Point(12, 12); this.button1.Name = "button1"; this.button1.Size = new System.Drawing.Size(75, 23); this.button1.TabIndex = 0; this.button1.Text = "button1"; this.button1.UseVisualStyleBackColor = true; // // textBox1 // this.textBox1.Location = new System.Drawing.Point(12, 41); this.textBox1.Multiline = true; this.textBox1.Name = "textBox1"; this.textBox1.Size = new System.Drawing.Size(468, 213); this.textBox1.TabIndex = 1; // // Form1 // this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F); this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font; this.ClientSize = new System.Drawing.Size(492, 266); this.Controls.Add(this.textBox1); this.Controls.Add(this.button1); this.Name = "Form1"; this.Text = "Form1"; this.ResumeLayout(false); this.PerformLayout(); } #endregion private System.Windows.Forms.Button button1; private System.Windows.Forms.TextBox textBox1; } }

Unique Alpha numeric generator

- by AAA

Hi, I want to give our users in the database a unique alpha-numeric id. I am using the code below, will this always generate a unique id? Below is the updated version of the code: old php: // Generate Guid function NewGuid() { $s = strtoupper(md5(uniqid(rand(),true))); $guidText = substr($s,0,8) . '-' . substr($s,8,4) . '-' . substr($s,12,4). '-' . substr($s,16,4). '-' . substr($s,20); return $guidText; } // End Generate Guid $Guid = NewGuid(); echo $Guid; echo "<br><br><br>"; New PHP: // Generate Guid function NewGuid() { $s = strtoupper(uniqid("something",true)); $guidText = substr($s,0,8) . '-' . substr($s,8,4) . '-' . substr($s,12,4). '-' . substr($s,16,4). '-' . substr($s,20); return $guidText; } // End Generate Guid $Guid = NewGuid(); echo $Guid; echo "<br><br><br>"; Will the second (new php) code guarantee 100% uniqueness. Final code: PHP // Generate Guid function NewGuid() { $s = strtoupper(uniqid(rand(),true)); $guidText = substr($s,0,8) . '-' . substr($s,8,4) . '-' . substr($s,12,4). '-' . substr($s,16,4). '-' . substr($s,20); return $guidText; } // End Generate Guid $Guid = NewGuid(); echo $Guid; $alphabet = '123456789abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ'; function base_encode($num, $alphabet) { $base_count = strlen($alphabet); $encoded = ''; while ($num >= $base_count) { $div = $num/$base_count; $mod = ($num-($base_count*intval($div))); $encoded = $alphabet[$mod] . $encoded; $num = intval($div); } if ($num) $encoded = $alphabet[$num] . $encoded; return $encoded; } function base_decode($num, $alphabet) { $decoded = 0; $multi = 1; while (strlen($num) > 0) { $digit = $num[strlen($num)-1]; $decoded += $multi * strpos($alphabet, $digit); $multi = $multi * strlen($alphabet); $num = substr($num, 0, -1); } return $decoded; } echo base_encode($Guid, $alphabet); } So for more stronger uniqueness, i am using the $Guid as the key generator. That should be ok right?

App is crashing as soon as UITableView gets reloaded

- by OhhMee

Hello, I'm developing an app where TableView needs to reload as soon as the login process gets completed. The app crashes with error EXC_BAD_ACCESS when the table data gets reloaded. It doesn't crash when I remove all case instances except case 0: What could be the reason behind it?

compareTo() method java is acting weird

Dynamic JSON Parsing in .NET with JsonValue

- by Rick Strahl

So System.Json has been around for a while in Silverlight, but it's relatively new for the desktop .NET framework and now moving into the lime-light with the pending release of ASP.NET Web API which is bringing a ton of attention to server side JSON usage. The JsonValue, JsonObject and JsonArray objects are going to be pretty useful for Web API applications as they allow you dynamically create and parse JSON values without explicit .NET types to serialize from or into. But even more so I think JsonValue et al. are going to be very useful when consuming JSON APIs from various services. Yes I know C# is strongly typed, why in the world would you want to use dynamic values? So many times I've needed to retrieve a small morsel of information from a large service JSON response and rather than having to map the entire type structure of what that service returns, JsonValue actually allows me to cherry pick and only work with the values I'm interested in, without having to explicitly create everything up front. With JavaScriptSerializer or DataContractJsonSerializer you always need to have a strong type to de-serialize JSON data into. Wouldn't it be nice if no explicit type was required and you could just parse the JSON directly using a very easy to use object syntax? That's exactly what JsonValue, JsonObject and JsonArray accomplish using a JSON parser and some sweet use of dynamic sauce to make it easy to access in code. Creating JSON on the fly with JsonValue Let's start with creating JSON on the fly. It's super easy to create a dynamic object structure. JsonValue uses the dynamic keyword extensively to make it intuitive to create object structures and turn them into JSON via dynamic object syntax. Here's an example of creating a music album structure with child songs using JsonValue:[TestMethod] public void JsonValueOutputTest() { // strong type instance var jsonObject = new JsonObject(); // dynamic expando instance you can add properties to dynamic album = jsonObject; album.AlbumName = "Dirty Deeds Done Dirt Cheap"; album.Artist = "AC/DC"; album.YearReleased = 1977; album.Songs = new JsonArray() as dynamic; dynamic song = new JsonObject(); song.SongName = "Dirty Deeds Done Dirt Cheap"; song.SongLength = "4:11"; album.Songs.Add(song); song = new JsonObject(); song.SongName = "Love at First Feel"; song.SongLength = "3:10"; album.Songs.Add(song); Console.WriteLine(album.ToString()); } This produces proper JSON just as you would expect: {"AlbumName":"Dirty Deeds Done Dirt Cheap","Artist":"AC\/DC","YearReleased":1977,"Songs":[{"SongName":"Dirty Deeds Done Dirt Cheap","SongLength":"4:11"},{"SongName":"Love at First Feel","SongLength":"3:10"}]} The important thing about this code is that there's no explicitly type that is used for holding the values to serialize to JSON. I am essentially creating this value structure on the fly by adding properties and then serialize it to JSON. This means this code can be entirely driven at runtime without compile time restraints of structure for the JSON output. Here I use JsonObject() to create a new object and immediately cast it to dynamic. JsonObject() is kind of similar in behavior to ExpandoObject in that it allows you to add properties by simply assigning to them. Internally, JsonValue/JsonObject these values are stored in pseudo collections of key value pairs that are exposed as properties through the DynamicObject functionality in .NET. The syntax gets a little tedious only if you need to create child objects or arrays that have to be explicitly defined first. Other than that the syntax looks like normal object access sytnax. Always remember though these values are dynamic - which means no Intellisense and no compiler type checking. It's up to you to ensure that the values you create are accessed consistently and without typos in your code. Note that you can also access the JsonValue instance directly and get access to the underlying type. This means you can assign properties by string, which can be useful for fully data driven JSON generation from other structures. Below you can see both styles of access next to each other:// strong type instance var jsonObject = new JsonObject(); // you can explicitly add values here jsonObject.Add("Entered", DateTime.Now); // expando style instance you can just 'use' properties dynamic album = jsonObject; album.AlbumName = "Dirty Deeds Done Dirt Cheap"; JsonValue internally stores properties keys and values in collections and you can iterate over them at runtime. You can also manipulate the collections if you need to to get the object structure to look exactly like you want. Again, if you've used ExpandoObject before JsonObject/Value are very similar in the behavior of the structure. Reading JSON strings into JsonValue The JsonValue structure supports importing JSON via the Parse() and Load() methods which can read JSON data from a string or various streams respectively. Essentially JsonValue includes the core JSON parsing to turn a JSON string into a collection of JsonValue objects that can be then referenced using familiar dynamic object syntax. Here's a simple example:[TestMethod] public void JsonValueParsingTest() { var jsonString = @"{""Name"":""Rick"",""Company"":""West Wind"",""Entered"":""2012-03-16T00:03:33.245-10:00""}"; dynamic json = JsonValue.Parse(jsonString); // values require casting string name = json.Name; string company = json.Company; DateTime entered = json.Entered; Assert.AreEqual(name, "Rick"); Assert.AreEqual(company, "West Wind"); } The JSON string represents an object with three properties which is parsed into a JsonValue object and cast to dynamic. Once cast to dynamic I can then go ahead and access the object using familiar object syntax. Note that the actual values - json.Name, json.Company, json.Entered - are actually of type JsonPrimitive and I have to assign them to their appropriate types first before I can do type comparisons. The dynamic properties will automatically cast to the right type expected as long as the compiler can resolve the type of the assignment or usage. The AreEqual() method oesn't as it expects two object instances and comparing json.Company to "West Wind" is comparing two different types (JsonPrimitive to String) which fails. So the intermediary assignment is required to make the test pass. The JSON structure can be much more complex than this simple example.

ASP.NET MVC ‘Extendable-hooks’ – ControllerActionInvoker class

- by nmarun

There’s a class ControllerActionInvoker in ASP.NET MVC. This can be used as one of an hook-points to allow customization of your application. Watching Brad Wilsons’ Advanced MP3 from MVC Conf inspired me to write about this class. What MSDN says: “Represents a class that is responsible for invoking the action methods of a controller.” Well if MSDN says it, I think I can instill a fair amount of confidence into what the class does. But just to get to the details, I also looked into the source code for MVC. Seems like the base class Controller is where an IActionInvoker is initialized: 1: protected virtual IActionInvoker CreateActionInvoker() { 2: return new ControllerActionInvoker(); 3: } In the ControllerActionInvoker (the O-O-B behavior), there are different ‘versions’ of InvokeActionMethod() method that actually call the action method in question and return an instance of type ActionResult. 1: protected virtual ActionResult InvokeActionMethod(ControllerContext controllerContext, ActionDescriptor actionDescriptor, IDictionary<string, object> parameters) { 2: object returnValue = actionDescriptor.Execute(controllerContext, parameters); 3: ActionResult result = CreateActionResult(controllerContext, actionDescriptor, returnValue); 4: return result; 5: } I guess that’s enough on the ‘behind-the-screens’ of this class. Let’s see how we can use this class to hook-up extensions. Say I have a requirement that the user should be able to get different renderings of the same output, like html, xml, json, csv and so on. The user will type-in the output format in the url and should the get result accordingly. For example: http://site.com/RenderAs/ – renders the default way (the razor view) http://site.com/RenderAs/xml http://site.com/RenderAs/csv … and so on where RenderAs is my controller. There are many ways of doing this and I’m using a custom ControllerActionInvoker class (even though this might not be the best way to accomplish this). For this, my one and only route in the Global.asax.cs is: 1: routes.MapRoute("RenderAsRoute", "RenderAs/{outputType}", 2: new {controller = "RenderAs", action = "Index", outputType = ""}); Here the controller name is ‘RenderAsController’ and the action that’ll get called (always) is the Index action. The outputType parameter will map to the type of output requested by the user (xml, csv…). I intend to display a list of food items for this example. 1: public class Item 2: { 3: public int Id { get; set; } 4: public string Name { get; set; } 5: public Cuisine Cuisine { get; set; } 6: } 7: 8: public class Cuisine 9: { 10: public int CuisineId { get; set; } 11: public string Name { get; set; } 12: } Coming to my ‘RenderAsController’ class. I generate an IList<Item> to represent my model. 1: private static IList<Item> GetItems() 2: { 3: Cuisine cuisine = new Cuisine { CuisineId = 1, Name = "Italian" }; 4: Item item = new Item { Id = 1, Name = "Lasagna", Cuisine = cuisine }; 5: IList<Item> items = new List<Item> { item }; 6: item = new Item {Id = 2, Name = "Pasta", Cuisine = cuisine}; 7: items.Add(item); 8: //... 9: return items; 10: } My action method looks like 1: public IList<Item> Index(string outputType) 2: { 3: return GetItems(); 4: } There are two things that stand out in this action method. The first and the most obvious one being that the return type is not of type ActionResult (or one of its derivatives). Instead I’m passing the type of the model itself (IList<Item> in this case). We’ll convert this to some type of an ActionResult in our custom controller action invoker class later. The second thing (a little subtle) is that I’m not doing anything with the outputType value that is passed on to this action method. This value will be in the RouteData dictionary and we’ll use this in our custom invoker class as well. It’s time to hook up our invoker class. First, I’ll override the Initialize() method of my RenderAsController class. 1: protected override void Initialize(RequestContext requestContext) 2: { 3: base.Initialize(requestContext); 4: string outputType = string.Empty; 5: 6: // read the outputType from the RouteData dictionary 7: if (requestContext.RouteData.Values["outputType"] != null) 8: { 9: outputType = requestContext.RouteData.Values["outputType"].ToString(); 10: } 11: 12: // my custom invoker class 13: ActionInvoker = new ContentRendererActionInvoker(outputType); 14: } Coming to the main part of the discussion – the ContentRendererActionInvoker class: 1: public class ContentRendererActionInvoker : ControllerActionInvoker 2: { 3: private readonly string _outputType; 4: 5: public ContentRendererActionInvoker(string outputType) 6: { 7: _outputType = outputType.ToLower(); 8: } 9: //... 10: } So the outputType value that was read from the RouteData, which was passed in from the url, is being set here in a private field. Moving to the crux of this article, I now override the CreateActionResult method. 1: protected override ActionResult CreateActionResult(ControllerContext controllerContext, ActionDescriptor actionDescriptor, object actionReturnValue) 2: { 3: if (actionReturnValue == null) 4: return new EmptyResult(); 5: 6: ActionResult result = actionReturnValue as ActionResult; 7: if (result != null) 8: return result; 9: 10: // This is where the magic happens 11: // Depending on the value in the _outputType field, 12: // return an appropriate ActionResult 13: switch (_outputType) 14: { 15: case "json": 16: { 17: JavaScriptSerializer serializer = new JavaScriptSerializer(); 18: string json = serializer.Serialize(actionReturnValue); 19: return new ContentResult { Content = json, ContentType = "application/json" }; 20: } 21: case "xml": 22: { 23: XmlSerializer serializer = new XmlSerializer(actionReturnValue.GetType()); 24: using (StringWriter writer = new StringWriter()) 25: { 26: serializer.Serialize(writer, actionReturnValue); 27: return new ContentResult { Content = writer.ToString(), ContentType = "text/xml" }; 28: } 29: } 30: case "csv": 31: controllerContext.HttpContext.Response.AddHeader("Content-Disposition", "attachment; filename=items.csv"); 32: return new ContentResult 33: { 34: Content = ToCsv(actionReturnValue as IList<Item>), 35: ContentType = "application/ms-excel" 36: }; 37: case "pdf": 38: string filePath = controllerContext.HttpContext.Server.MapPath("~/items.pdf"); 39: controllerContext.HttpContext.Response.AddHeader("content-disposition", 40: "attachment; filename=items.pdf"); 41: ToPdf(actionReturnValue as IList<Item>, filePath); 42: return new FileContentResult(StreamFile(filePath), "application/pdf"); 43: 44: default: 45: controllerContext.Controller.ViewData.Model = actionReturnValue; 46: return new ViewResult 47: { 48: TempData = controllerContext.Controller.TempData, 49: ViewData = controllerContext.Controller.ViewData 50: }; 51: } 52: } A big method there! The hook I was talking about kinda above actually is here. This is where different kinds / formats of output get returned based on the output type requested in the url. When the _outputType is not set (string.Empty as set in the Global.asax.cs file), the razor view gets rendered (lines 45-50). This is the default behavior in most MVC applications where-in a view (webform/razor) gets rendered on the browser. As you see here, this gets returned as a ViewResult. But then, for an outputType of json/xml/csv, a ContentResult gets returned, while for pdf, a FileContentResult is returned. Here are how the different kinds of output look like: This is how we can leverage this feature of ASP.NET MVC to developer a better application. I’ve used the iTextSharp library to convert to a pdf format. Mike gives quite a bit of detail regarding this library here. You can download the sample code here. (You’ll get an option to download once you open the link). Verdict: Hot chocolate: $3; Reebok shoes: $50; Your first car: $3000; Being able to extend a web application: Priceless.

ASP.NET MVC 2 RTM Unit Tests not compiling

- by nmarun

I found something weird this time when it came to ASP.NET MVC 2 release. A very handful of people ‘made noise’ about the release.. at least on the asp.net blog site, usually there’s a big ‘WOOHAA… <something> is released’, kind of a thing. Hmm… but here’s the reason I’m writing this post. I’m not sure how many of you read the release notes before downloading the version.. I did, I did, I did. Now there’s a ‘Known issues’ section in the document and I’m quoting the text as is from this section: Unit test project does not contain reference to ASP.NET MVC 2 project: If the Solution Explorer window is hidden in Visual Studio, when you create a new ASP.NET MVC 2 Web application project and you select the option Yes, create a unit test project in the Create Unit Test Project dialog box, the unit test project is created but does not have a reference to the associated ASP.NET MVC 2 project. When you build the solution, Visual Studio will display compilation errors and the unit tests will not run. There are two workarounds. The first workaround is to make sure that the Solution Explorer is displayed when you create a new ASP.NET MVC 2 Web application project. If you prefer to keep Solution Explorer hidden, the second workaround is to manually add a project reference from the unit test project to the ASP.NET MVC 2 project. This definitely looks like a bug to me and see below for a visual: At the top right corner you’ll see that the Solution Explorer is set to auto hide and there’s no reference for the TestMvc2 project and that is the reason we get compilation errors without even writing a single line of code. So thanks to <VeryBigFont>ME</VeryBigFont> and <VerySmallFont>Microsoft</VerySmallFont>) , we’ve shown the world how to resolve a major issue and to live in Peace with the rest of humanity!

Oracle Database 11g R2 támogatott SAP alatt is

- by Lajos Sárecz

Húsvét óta már SAP alatt is használható az Oracle Database 11g R2. Köztudott, hogy az SAP csak a Release 2-re ad ki támogatást, így ez most egy igazán örömteli hír az SAP felhasználóknak, hiszen az alábbi 11g R2 újdonságokat tudják alkalmazni SAP környezetben: • Advanced Compression opció (táblára, RMAN mentésre, expdp-re, Data Guard hálózatra) • Real Application Testing • Oracle Database 11g Release 2 Database Vault • Oracle Database 11g Release 2 RAC • Advanced Encryption táblaterekre, RMAN mentésekre, expdp-re, Data Guard hálózatra • Direct NFS • Deferred Segments • Online Patching Azaz például tömöríthetové válik az SAP adatbázisa, vagy az abból készített mentések. Az eddigi tapasztalatok szerint a tömörítés aránya adatbázistól függoen 2-4-szeres. Az adatbázis upgrade és minden egyéb adatbázis infrastruktúrát érinto változatatás kockázata jelentosen csökkentheto lesz a Real Application Testing alkalmazásával. A rendszergazdai szerepkörök szeparaláhatóvá válnak a Database Vault felhasználásával. A Real Application Clusters 11g R2 újdonságai is elérheto lesznek. A Transparent Data Encryption révén a táblaterek és a mentések titkosíthatók úgy, hogy az alkalmazás számára mindez transzparens, azonban a médiához közvetlenül hozzáférve nem lesznek visszafejthetok az adatok. Támogatott lesz a Direct NFS kliens, ezzel NFS elérési sebesség jelentosen javul. A Deffered Segments révén pedig a tábla szegmensek csak akkor kerülnek lefoglalásra, amikor adat kerül a táblába. Ez azért hasznos, mert általában alkalmazások telepítésekor létrejön minden tábla, azonban sok táblába nem kerül adat. Ezáltal mind a telepítés ideje, mind az adatbázis mérete csökkentheto. Az Online Patching pedig lehetové teszi a leállításmentes patch telepítést. Hát azt gondolom ezek vonzó lehetoségek, érdemes betervezni a közeljövobe az SAP rendszerek alatti adatbázis frissítését, hiszen a 10g verzió Premier Support idén nyáron lejár. Az upgrade-hez pedig mindenképp javaslom a Real Application Testing használatát, amivel az éles terhelés mellett teszthelheto teszt környezetben az upgrade. A Sun Oracle Database Machine és az Exadata sajnos még nem támogatott SAP alatt, mivel az ASM certifikáció még nem zárult le. A hírek szerint 2011 elejére várható, hogy ez megtörténik.

Passing multiple simple POST Values to ASP.NET Web API

- by Rick Strahl

A few weeks backs I posted a blog post about what does and doesn't work with ASP.NET Web API when it comes to POSTing data to a Web API controller. One of the features that doesn't work out of the box - somewhat unexpectedly - is the ability to map POST form variables to simple parameters of a Web API method. For example imagine you have this form and you want to post this data to a Web API end point like this via AJAX: <form> Name: <input type="name" name="name" value="Rick" /> Value: <input type="value" name="value" value="12" /> Entered: <input type="entered" name="entered" value="12/01/2011" /> <input type="button" id="btnSend" value="Send" /> </form> <script type="text/javascript"> $("#btnSend").click( function() { $.post("samples/PostMultipleSimpleValues?action=kazam", $("form").serialize(), function (result) { alert(result); }); }); </script> or you might do this more explicitly by creating a simple client map and specifying the POST values directly by hand:$.post("samples/PostMultipleSimpleValues?action=kazam", { name: "Rick", value: 1, entered: "12/01/2012" }, $("form").serialize(), function (result) { alert(result); }); On the wire this generates a simple POST request with Url Encoded values in the content:POST /AspNetWebApi/samples/PostMultipleSimpleValues?action=kazam HTTP/1.1 Host: localhost User-Agent: Mozilla/5.0 (Windows NT 6.2; WOW64; rv:15.0) Gecko/20100101 Firefox/15.0.1 Accept: application/json Connection: keep-alive Content-Type: application/x-www-form-urlencoded; charset=UTF-8 X-Requested-With: XMLHttpRequest Referer: http://localhost/AspNetWebApi/FormPostTest.html Content-Length: 41 Pragma: no-cache Cache-Control: no-cachename=Rick&value=12&entered=12%2F10%2F2011 Seems simple enough, right? We are basically posting 3 form variables and 1 query string value to the server. Unfortunately Web API can't handle request out of the box. If I create a method like this:[HttpPost] public string PostMultipleSimpleValues(string name, int value, DateTime entered, string action = null) { return string.Format("Name: {0}, Value: {1}, Date: {2}, Action: {3}", name, value, entered, action); }You'll find that you get an HTTP 404 error and { "Message": "No HTTP resource was found that matches the request URI…"} Yes, it's possible to pass multiple POST parameters of course, but Web API expects you to use Model Binding for this - mapping the post parameters to a strongly typed .NET object, not to single parameters. Alternately you can also accept a FormDataCollection parameter on your API method to get a name value collection of all POSTed values. If you're using JSON only, using the dynamic JObject/JValue objects might also work. ModelBinding is fine in many use cases, but can quickly become overkill if you only need to pass a couple of simple parameters to many methods. Especially in applications with many, many AJAX callbacks the 'parameter mapping type' per method signature can lead to serious class pollution in a project very quickly. Simple POST variables are also commonly used in AJAX applications to pass data to the server, even in many complex public APIs. So this is not an uncommon use case, and - maybe more so a behavior that I would have expected Web API to support natively. The question "Why aren't my POST parameters mapping to Web API method parameters" is already a frequent one… So this is something that I think is fairly important, but unfortunately missing in the base Web API installation. Creating a Custom Parameter Binder Luckily Web API is greatly extensible and there's a way to create a custom Parameter Binding to provide this functionality! Although this solution took me a long while to find and then only with the help of some folks Microsoft (thanks Hong Mei!!!), it's not difficult to hook up in your own projects. It requires one small class and a GlobalConfiguration hookup. Web API parameter bindings allow you to intercept processing of individual parameters - they deal with mapping parameters to the signature as well as converting the parameters to the actual values that are returned. Here's the implementation of the SimplePostVariableParameterBinding class:public class SimplePostVariableParameterBinding : HttpParameterBinding { private const string MultipleBodyParameters = "MultipleBodyParameters"; public SimplePostVariableParameterBinding(HttpParameterDescriptor descriptor) : base(descriptor) { } /// <summary> /// Check for simple binding parameters in POST data. Bind POST /// data as well as query string data /// </summary> public override Task ExecuteBindingAsync(ModelMetadataProvider metadataProvider, HttpActionContext actionContext, CancellationToken cancellationToken) { // Body can only be read once, so read and cache it NameValueCollection col = TryReadBody(actionContext.Request); string stringValue = null; if (col != null) stringValue = col[Descriptor.ParameterName]; // try reading query string if we have no POST/PUT match if (stringValue == null) { var query = actionContext.Request.GetQueryNameValuePairs(); if (query != null) { var matches = query.Where(kv => kv.Key.ToLower() == Descriptor.ParameterName.ToLower()); if (matches.Count() > 0) stringValue = matches.First().Value; } } object value = StringToType(stringValue); // Set the binding result here SetValue(actionContext, value); // now, we can return a completed task with no result TaskCompletionSource<AsyncVoid> tcs = new TaskCompletionSource<AsyncVoid>(); tcs.SetResult(default(AsyncVoid)); return tcs.Task; } private object StringToType(string stringValue) { object value = null; if (stringValue == null) value = null; else if (Descriptor.ParameterType == typeof(string)) value = stringValue; else if (Descriptor.ParameterType == typeof(int)) value = int.Parse(stringValue, CultureInfo.CurrentCulture); else if (Descriptor.ParameterType == typeof(Int32)) value = Int32.Parse(stringValue, CultureInfo.CurrentCulture); else if (Descriptor.ParameterType == typeof(Int64)) value = Int64.Parse(stringValue, CultureInfo.CurrentCulture); else if (Descriptor.ParameterType == typeof(decimal)) value = decimal.Parse(stringValue, CultureInfo.CurrentCulture); else if (Descriptor.ParameterType == typeof(double)) value = double.Parse(stringValue, CultureInfo.CurrentCulture); else if (Descriptor.ParameterType == typeof(DateTime)) value = DateTime.Parse(stringValue, CultureInfo.CurrentCulture); else if (Descriptor.ParameterType == typeof(bool)) { value = false; if (stringValue == "true" || stringValue == "on" || stringValue == "1") value = true; } else value = stringValue; return value; } /// <summary> /// Read and cache the request body /// </summary> /// <param name="request"></param> /// <returns></returns> private NameValueCollection TryReadBody(HttpRequestMessage request) { object result = null; // try to read out of cache first if (!request.Properties.TryGetValue(MultipleBodyParameters, out result)) { // parsing the string like firstname=Hongmei&lastname=Ge result = request.Content.ReadAsFormDataAsync().Result; request.Properties.Add(MultipleBodyParameters, result); } return result as NameValueCollection; } private struct AsyncVoid { } } The ExecuteBindingAsync method is fired for each parameter that is mapped and sent for conversion. This custom binding is fired only if the incoming parameter is a simple type (that gets defined later when I hook up the binding), so this binding never fires on complex types or if the first type is not a simple type. For the first parameter of a request the Binding first reads the request body into a NameValueCollection and caches that in the request.Properties collection. The request body can only be read once, so the first parameter request reads it and then caches it. Subsequent parameters then use the cached POST value collection. Once the form collection is available the value of the parameter is read, and the value is translated into the target type requested by the Descriptor. SetValue writes out the value to be mapped. Once you have the ParameterBinding in place, the binding has to be assigned. This is done along with all other Web API configuration tasks at application startup in global.asax's Application_Start:GlobalConfiguration.Configuration.ParameterBindingRules .Insert(0, (HttpParameterDescriptor descriptor) => { var supportedMethods = descriptor.ActionDescriptor.SupportedHttpMethods; // Only apply this binder on POST and PUT operations if (supportedMethods.Contains(HttpMethod.Post) || supportedMethods.Contains(HttpMethod.Put)) { var supportedTypes = new Type[] { typeof(string), typeof(int), typeof(decimal), typeof(double), typeof(bool), typeof(DateTime) }; if (supportedTypes.Where(typ => typ == descriptor.ParameterType).Count() > 0) return new SimplePostVariableParameterBinding(descriptor); } // let the default bindings do their work return null; }); The ParameterBindingRules.Insert method takes a delegate that checks which type of requests it should handle. The logic here checks whether the request is POST or PUT and whether the parameter type is a simple type that is supported. Web API calls this delegate once for each method signature it tries to map and the delegate returns null to indicate it's not handling this parameter, or it returns a new parameter binding instance - in this case the SimplePostVariableParameterBinding. Once the parameter binding and this hook up code is in place, you can now pass simple POST values to methods with simple parameters. The examples I showed above should now work in addition to the standard bindings. Summary Clearly this is not easy to discover. I spent quite a bit of time digging through the Web API source trying to figure this out on my own without much luck. It took Hong Mei at Micrsoft to provide a base example as I asked around so I can't take credit for this solution :-). But once you know where to look, Web API is brilliantly extensible to make it relatively easy to customize the parameter behavior. I'm very stoked that this got resolved - in the last two months I've had two customers with projects that decided not to use Web API in AJAX heavy SPA applications because this POST variable mapping wasn't available. This might actually change their mind to still switch back and take advantage of the many great features in Web API. I too frequently use plain POST variables for communicating with server AJAX handlers and while I could have worked around this (with untyped JObject or the Form collection mostly), having proper POST to parameter mapping makes things much easier. I said this in my last post on POST data and say it again here: I think POST to method parameter mapping should have been shipped in the box with Web API, because without knowing about this limitation the expectation is that simple POST variables map to parameters just like query string values do. I hope Microsoft considers including this type of functionality natively in the next version of Web API natively or at least as a built-in HttpParameterBinding that can be just added. This is especially true, since this binding doesn't affect existing bindings.

Wireless will not connect

- by azz0r

Hello, I have installed Ubuntu 10.10 on the same machine as my windows setup. However, it will not connect to my wireless network. It can see its there, it can attempt to connect, yet it will never connect. It will keep bringing up the password prompt everyso often. I have tried turning my security to WEP, I ended up turning it back to WPA2. It is set to AES (noted a few threads on google about that). Can you assist? I would love to dive into Ubuntu, but without the internet its pointless. --- lshw -C network --- *-network description: Ethernet interface product: RTL8111/8168B PCI Express Gigabit Ethernet controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:02:00.0 logical name: eth0 version: 02 serial: 00:1d:92:ea:cc:62 capacity: 1GB/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix vpd bus_master cap_list rom ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8168 driverversion=8.020.00-NAPI duplex=half latency=0 link=no multicast=yes port=twisted pair resources: irq:29 ioport:e800(size=256) memory:feaff000-feafffff memory:f8ff0000-f8ffffff(prefetchable) memory:feac0000-feadffff(prefetchable) *-network description: Wireless interface physical id: 1 logical name: wlan0 serial: 00:15:af:72:a4:38 capabilities: ethernet physical wireless configuration: broadcast=yes multicast=yes wireless=IEEE 802.11bgn --- iwconfig ---- lo no wireless extensions. eth0 no wireless extensions. wlan0 IEEE 802.11bgn ESSID:"Wuggawoo" Mode:Managed Frequency:2.437 GHz Access Point: Not-Associated Tx-Power=9 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:on --- cat /etc/network/interfaces ---- auto lo iface lo inet loopback logs deamon.log --- Jan 19 04:17:09 ubuntu wpa_supplicant[1289]: Authentication with 94:44:52:0d:22:0d timed out.
