• Space in Directory Parameter of svcutil.exe

  - by Drew Frisk

  I'm attempting to download metadata for a WCF service using svcutil but I'm running into issues with the /directory:< parameter. The directory I want to save to has a space in it: C:\Service References\Logging so when I execute /t:metadata I receive the following error: Error: The directory 'C:\Program Files (x86)\Microsoft SDKs\Windows\v8.0A\bin\NETFX 4.0 Tools\References\Logging' could not be found. Verify that the directory exists and that you have the appropriate permissions to read it. It looks to me like the space in "Service References" is causing the issue. From my understanding of command shell (which is very little) spaces act as delimiters for an executable. So I tried escaping the space with a carrot Service^ References and surrounding the path in double quotes "C:\Service References\Logging" but neither of those seem to be working, as the /directory: parameter doesn't recognize them as valid characters in the value. I haven't been able to find any direction in regards to this and svcutil, so I'm at a loss right now. I could download the files to a temp folder and then move them, but I would prefer not to take that approach. I would appreciate any direction that could be given on trying to resolve this. Thanks in advance.

• Run a .java file using ProcessBuilder

  - by David K

  I'm a novice programmer working in Eclipse, and I need to get multiple processes running (this is going to be a simulation of a multi-computer system). My initial hackup used multiple threads to multiple classes, but now I'm trying to replace the threads with processes. From my reading, I've gleaned that ProcessBuilder is the way to go. I have tried many many versions of the input you see below, but cannot for the life of me figure out how to properly use it. I am trying to run the .java files I previously created as classes (which I have modified). I eventually just made a dummy test.java to make sure my process is working properly - its only function is to print that it ran. My code for the two files are below. Am I using ProcessBuilder correctly? Is this the correct way to read the output of my subprocess? Any help would be much appreciated. David primary process package Control; import java.io.*; import java.lang.*; public class runSPARmatch { /** * @param args */ public static void main(String args[]) { try { ProcessBuilder broker = new ProcessBuilder("javac.exe","test.java","src\\Broker\\"); Process runBroker = broker.start(); Reader reader = new InputStreamReader(runBroker.getInputStream()); int ch; while((ch = reader.read())!= -1) System.out.println((char)ch); reader.close(); runBroker.waitFor(); System.out.println("Program complete"); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } subprocess package Broker; public class test { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub System.out.println("This works"); } }

• Optimizing mathematics on arrays of floats in Ada 95 with GNATC

  - by mat_geek

  Consider the bellow code. This code is supposed to be processing data at a fixed rate, in one second batches, It is part of an overal system and can't take up too much time. When running over 100 lots of 1 seconds worth of data the program takes 35 seconds; or 35%. How do I improce the code to get the processing time down to a minimum? The code will be running on an Intel Pentium-M which is a P3 with SSE2. package FF is new Ada.Numerics.Generic_Elementary_Functions(Float); N : constant Integer := 820; type A is array(1 .. N) of Float; type A3 is array(1 .. 3) of A; procedure F(state : in out A3; result : out A3; l : in A; r : in A) is s : Float; t : Float; begin for i in 1 .. N loop t := l(i) + r(i); t := t / 2.0; state(1)(i) := t; state(2)(i) := t * 0.25 + state(2)(i) * 0.75; state(3)(i) := t * 1.0 /64.0 + state(2)(i) * 63.0 /64.0; for r in 1 .. 3 loop s := state(r)(i); t := FF."**"(s, 6.0) + 14.0; if t > MAX then t := MAX; elsif t < MIN then t := MIN; end if; result(r)(i) := FF.Log(t, 2.0); end loop; end loop; end;

• Debugging NSoperation BAD ACCESS within graphics context

  - by Joe

  I tried everything to debug this one but I can't get to the bottom of it. This code lives in a subclass of NSOperation which is processed from a queue: (borders is an ivar NSArray containing 5 UIimage objects) NSMutableArray *images = [[NSMutableArray alloc] init]; for (unsigned i = 0; i < 5; i++) { CGSize size = CGSizeMake(60, 60); UIGraphicsBeginImageContext(size); CGPoint thumbPoint = CGPointMake(6, 6); [controller.image drawAtPoint:thumbPoint]; CGPoint borderPoint = CGPointMake(0, 0); [[borders objectAtIndex:i] drawAtPoint:borderPoint]; [images addObject:UIGraphicsGetImageFromCurrentImageContext()]; UIGraphicsEndImageContext(); } [images release]; The code works fine most of the time but when I push the iphone by access subviews and pressing lots of buttons on the UI I either get this exception which is trapped by the operation: Exception Load view: *** -[NSCFArray insertObject:atIndex:]: attempt to insert nil or I get this: Program received signal: “EXC_BAD_ACCESS”. The exception is caused because UIGraphicsGetImageFromCurrentImageContext() return nil. I don't know how to debug the EXC_BAD_ACCESS but I'm guessing that this error (in fact both of these errors) is caused by low memory. The debugger stops at the line: [controller.image drawAtPoint:thumbPoint]; As I mentioned I've trapped the exception so I can live with that but the EXC_BAD_ACCESS is more serious. IF this is memory related how can I tell and is it possible to increase the memory available to NSOperation?

  Hello All, Ive been following a tutorial to implement a search bar ( http://www.iphonesdkarticles.com/2009/01/uitableview-searching-table-view.html ) However I cant seem to push different views. Here is what my didsSelectRowAtIndexPath looks like. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSString *selectedCountry = nil; if(searching) selectedCountry = [copyListOfItems objectAtIndex:indexPath.row]; else { NSDictionary *dictionary = [listOfItems objectAtIndex:indexPath.section]; NSArray *array = [dictionary objectForKey:@"Countries"]; selectedCountry = [array objectAtIndex:indexPath.row]; } //Initialize the detail view controller and display it. if ([[listOfItems objectAtIndex:indexPath.row] isEqual:@"neon"]){ Neon *abo = [[Neon alloc] initWithNibName:@"Neon" bundle:nil]; //dvController.selectedCountry = selectedCountry; [self.navigationController pushViewController:abo animated:YES]; [abo release]; } } And here is the debuger message when I click on neon: 2010-05-09 08:47:27.516 iTeachU[3821:307] * Terminating app due to uncaught exception 'NSRangeException', reason: ' -[NSMutableArray objectAtIndex:]: index 60 beyond bounds [0 .. 0]' ** Call stack at first throw: terminate called after throwing an instance of 'NSException' Program received signal: “SIGABRT”.

• Generate exe in .Net

  - by rwallace

  In .Net, you can generate byte code in memory, and presumably save the resulting program to a .exe file. To do the first step, I have the following test code adapted from http://www.code-magazine.com/Article.aspx?quickid=0301051 var name = new AssemblyName(); name.Name = "MyAssembly"; var ad = Thread.GetDomain(); var ab = ad.DefineDynamicAssembly(name, AssemblyBuilderAccess.Run); var mb = ab.DefineDynamicModule("MyModule"); var theClass = mb.DefineType("MathOps", TypeAttributes.Public); var retType = typeof(System.Int32); var parms = new Type[2]; parms[0] = typeof(System.Int32); parms[1] = typeof(System.Int32); var meb = theClass.DefineMethod("ReturnSum", MethodAttributes.Public, retType, parms); var gen = meb.GetILGenerator(); gen.Emit(OpCodes.Ldarg_1); gen.Emit(OpCodes.Ldarg_2); gen.Emit(OpCodes.Add_Ovf); gen.Emit(OpCodes.Stloc_0); gen.Emit(OpCodes.Br_S); gen.Emit(OpCodes.Ldloc_0); gen.Emit(OpCodes.Ret); theClass.CreateType(); How do you do the second step, and save the result to a .exe?

• Lazarus - why I can't assign event to run-time component?

  - by Garret Raziel

  Hello, I have this Lazarus program: unit Unit2; {$mode objfpc}{$H+} interface uses Classes, SysUtils, FileUtil, LResources, Forms, Controls, Graphics, Dialogs, StdCtrls, ComCtrls; type { TForm2 } TForm2 = class(TForm) procedure OnTlacitkoClick(Sender: TObject); procedure FormClose(Sender: TObject; var CloseAction: TCloseAction); procedure FormCreate(Sender: TObject); tlac:TButton; private { private declarations } public { public declarations } end; var Form2: TForm2; implementation { TForm2 } procedure TForm2.OnTlacitkoClick(Sender: TObject); begin showmessage('helloworld'); end; procedure TForm2.FormCreate(Sender: TObject); var i,j:integer; begin tlac:=TButton.Create(Form2); tlac.OnClick:=OnTlacitkoClick; tlac.Parent:=Form2; tlac.Left:=100; tlac.Top:=100; end; initialization {$I unit2.lrs} end. but compiler says: unit2.pas(63,32) Error: Wrong number of parameters specified for call to "OnTlacitkoClick" in tlac.OnClick:=OnTlacitkoClick; expression. I have searched and think that this is legal expression in Delphi. I want simply to registrate OnTlacitkoClick as tlac.OnClick event,not to call this procedure. Is there somethink wrong with the code or must I do it different in Lazarus/Freepascal? Thanks.

• How to connect to SQLServer 2k5 using Ruby 1.8.7 over W2k3 with active record 2.3.5

  - by Luke

  Hi all, sorry for the blast. I'm trying to connect to an SQLServer 2k5 using Ruby 1.8.7 over W2k3 with active record 2.3.5. But, when I ran 'rake migrate' it throws the following: rake migrate --trace Hoe.new {...} deprecated. Switch to Hoe.spec. Invoke migrate (first_time) Invoke environment (first_time) Execute environment Execute migrate rake aborted! no such file to load -- odbc (...) C:/Program Files/test/Rakefile:146 (...) So, my Rakefile in the line 146 says: ActiveRecord::Migrator.migrate('db/migrate', ENV["VERSION"] ? ENV["VERSION"].to_i : nil ) The database.yml has been configured in so many ways without success. I've tried setup to mode in odbc, to configure a system dsn, to completely use the activerecord support for sqlserver but no success at all. The same Rakefile works fine over Postgres and Oracle with the proper gems installed off course. But I cann't get this work. Any help will be appreciated. Thanks in advance!

• Why does VBA Find loop fail when called from Evaluate?

  - by Abiel

  I am having some problems running a find loop inside of a subroutine when the routine is called using the Application.Evaluate or ActiveSheet.Evaluate method. For example, in the code below, I define a subroutine FindSub() which searches the sheet for a string "xxx". The routine CallSub() calls the FindSub() routine using both a standard Call statement and Evaluate. When I run Call FindSub, everything will work as expected: each matching address gets printed out to the immediate window and we get a final message "Finished up" when the code is done. However, when I do Application.Evaluate "FindSub()", only the address of the first match gets printed out, and we never reach the "Finished up" message. In other words, an error is encountered after the Cells.FindNext line as the loop tries to evaluate whether it should continue, and program execution stops without any runtime error being printed. I would expect both Call FindSub and Application.Evaluate "FindSub()" to yield the same results in this case. Can someone explain why they do not, and if possible, a way to fix this? Thanks. Note: In this example I obviously do not need to use Evaluate. This version is simplified to just focus on the particular problem I am having in a more complex situation. Sub CallSub() Call FindSub Application.Evaluate "FindSub()" End Sub Sub FindSub() Dim rngFoundCell As Range Dim rngFirstCell As Range Set rngFoundCell = Cells.Find(What:="xxx", after:=ActiveCell, LookIn:=xlValues, _ LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, _ MatchCase:=False, SearchFormat:=False) If Not rngFoundCell Is Nothing Then Set rngFirstCell = rngFoundCell Do Debug.Print rngFoundCell.Address Set rngFoundCell = Cells.FindNext(after:=rngFoundCell) Loop Until (rngFoundCell Is Nothing) Or (rngFoundCell.Address = rngFirstCell.Address) End If Debug.Print "Finished up" End Sub

• How to change one Button background in a gridview? -- Android

  - by Tstop Studios

  I have a GridView with 16 ImageView buttons. My program makes a random number and when the user clicks a button in the gridview, i want it to take the random number (0-15) and set the background of the tile with the same position as the random number (0-15) to a different image. How can I just change one of the buttons background? Here's my code so far: public class ButtonHider extends Activity { Random random = new Random(); int pos; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.button_hider); pos = random.nextInt(15); GridView gridview = (GridView) findViewById(R.id.gvBH); gridview.setAdapter(new ImageAdapter(this)); gridview.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View v, int position, long id) { pos = random.nextInt(16); if (position == pos) { Toast.makeText(ButtonHider.this, "Found Me!", Toast.LENGTH_SHORT).show(); } else { Toast.makeText(ButtonHider.this, "Try Again!!", Toast.LENGTH_SHORT).show(); } } }); } public class ImageAdapter extends BaseAdapter { private Context mContext; public ImageAdapter(Context c) { mContext = c; } public int getCount() { return 16; } public Object getItem(int position) { return null; } public long getItemId(int position) { return 0; } // create a new ImageView for each item referenced by the Adapter public View getView(int position, View convertView, ViewGroup parent) { ImageView imageView; if (convertView == null) { // if it's not recycled, initialize some // attributes imageView = new ImageView(mContext); imageView.setLayoutParams(new GridView.LayoutParams(100, 100)); imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); imageView.setPadding(15, 15, 15, 15); } else { imageView = (ImageView) convertView; } imageView.setImageResource(R.drawable.bh_b); return imageView; } } }

• debugging finite state machine spell checker code

• asp.net Membership : Extending Role membership?

  - by mark smith

  Hi there, I am been taking a look at asp.net membership and it seems to provide everything that i need but i need some kind of custom Role functionality. Currently i can add user to a role, great. But i also need to be able to add Permissions to Roles.. i.e. Role: Editor Permissions: Can View Editor Menu, Can Write to Editors Table, Can Delete Entries in Editors Table. Currently it doesn't support this, The idea behind this is to create a admin option in my program to create a role and then assign permissions to a role to say "allow the user to view a certain part of the application", "allow the user to open a menu item" Any ideas how i would implement soemthing like this? I presume a custom ROLE provider but i was wondering if some kind of framework extension existed already without rolling my own? Or anybody knows a good tutorial of how to tackle this issue? I am quite happy with what asp.net SQL provider has created in terms of tables etc... but i think i need to extend this by adding another table called RolesPermissions and then I presume :-) adding some kind of enumeration into the table for each valid permission?? THanks in advance

• Working with ieee format numbers in ARM

  - by Jake Sellers

  I'm trying to write an ARM program that will convert an ieee number to a TNS format number. TNS is a format used by some super computers, and is similar to ieee but different. I'm trying to use several masks to place the three different "part" of the ieee number in separate registers so I can move them around accordingly. Here is my unpack subroutine: UnpackIEEE LDR r1, SMASK ;load the sign bit mask into r1 LDR r2, EMASK ;load the exponent mask into r2 LDR r3, GMASK ;load the significand mask into r3 AND r4, r0, r1 ;apply sign mask to IEEE and save into r4 AND r5, r0, r2 ;apply exponent mask to IEEE and save into r5 AND r6, r0, r3 ;apply significand mask to IEEE and save into r6 MOV pc, r14 ;return And here are the masks and number declarations so you can understand: IEEE DCD 0x40300000 ;2.75 decimal or 01000000001100000000000000000000 binary SMASK DCD 0x80000000 ;Sign bit mask EMASK DCD 0x7F800000 ;Exponent mask GMASK DCD 0x007FFFFF ;Significand mask When I step through with the debugger, the results I get are not what I expect after working through it on paper. EDIT: What I mean, is that after the subroutine runs, registers 4, 5, and 6 all remain 0. I can't figure out why the masks are not working. I think I do not fully understand how the number is being stored in the register or using the masks wrong. Any help appreciated. If you need more info just ask. EDIT: entry point: Very simple, just trying to get these subroutines working. ENTRY LDR r1, IEEE ;load IEEE num into r1 BL UnpackIEEE ;call unpack sub SWI SWI_Exit ;finish

• Out of Core Implementation of a Quadtree

  - by Nima

  Hi, I am trying to build a Quadtree data structure(or let's just say a tree) on the secondary memory(Hard Disk). I have a C++ program to do so and I use fopen to create the files. Also, I am using tesseral coding to store each cell in a file named with its corresponding code to store it on the disk in one directory. The problem is that after creating about 1,100 files, fopen just returns NULL and stops creating new files. I can create further files manually in that directory, but using C++ it can not create any further files. I know about max limit of inode on ext3 filesystem which is (from Wikipedia) 32,000 but mine is way less than that, also note that I can create files manually on the disk; just not through fopen. Also, I really appreciate any idea regarding the best way to store a very dynamic quadtree on disk(I need the nodes to be in separate files and the quadtree might have a depth of 50). Using nested directories is one idea, but I think it will slow down the performance because of following the links on the filesystem to access the file. Thanks, Nima

• Redirect C++ std::clog to syslog on Unix

  - by kriss

  I work on Unix on a C++ program that send messages to syslog. The current code uses the syslog system call that works like printf. Now I would prefer to use a stream for that purpose instead, typically the built-in std::clog. But clog merely redirect output to stderr, not to syslog and that is useless for me as I also use stderr and stdout for other purposes. I've seen in another answer that it's quite easy to redirect it to a file using rdbuf() but I see no way to apply that method to call syslog as openlog does not return a file handler I could use to tie a stream on it. Is there another method to do that ? (looks pretty basic for unix programming) ? Edit: I'm looking for a solution that does not use external library. What @Chris is proposing could be a good start but is still a bit vague to become the accepted answer. Edit: using Boost.IOStreams is OK as my project already use Boost anyway. Linking with external library is possible but is also a concern as it's GPL code. Dependencies are also a burden as they may conflict with other components, not be available on my Linux distribution, introduce third-party bugs, etc. If this is the only solution I may consider completely avoiding streams... (a pity).

• Data in J2ME RecordStore does not persist across sessions

  - by Botond Balázs

  I'm building a mobile app with J2ME, and I've found that the data I write into a RecordStore can be accessed while the program is still running but it is lost after quitting and restarting it. No exception is thrown, the data is simply lost. UPDATE: Thanks everyone for your suggestions. I'm using NetBeans on Windows 7. I'm not sure if it is using the WTK version I have previously installed or another one it has installed somewhere else. I've checked my WTK folder for the files Pavel wrote about, but couldn't find them. Now I'm testing the features requiring persistence on my phone and everything else in the emulator, but it would of course be much better to be able to test everything in the emulator. private RecordStore recordStore = null; public MyMIDlet() { readStuff(); // output: nothing found in recordStore :( saveStuff(); readStuff(); // output: stuff } private void readStuff() { try { recordStore = RecordStore.openRecordStore(REC_STORE, true); int n = recordStore.getNumRecords(); String stuff; if (n == 0) { stuff = "nothing found in recordStore :("; } else { stuff = new String(recordStore.getRecord(1)); } System.out.println(stuff); } catch (Exception e) { System.out.println("Exception occured in readStuff: " + e.getMessage()); } finally { if (recordStore != null) { try { recordStore.closeRecordStore(); } catch (Exception e) { // ignore } } } } private void saveStuff() { try { recordStore = RecordStore.openRecordStore(REC_STORE, true); int n = recordStore.getNumRecords(); byte[] stuff = "stuff".getBytes(); recordStore.addRecord(stuff, 0, stuff.length); } catch (Exception e) { System.out.println("Exception occured in saveStuff: " + e.getMessage()); } finally { if (recordStore != null) { try { recordStore.closeRecordStore(); } catch (Exception e) { // ignore } } } }

• C malloc assertion help

  - by Chris

  I am implementing a divide and conquer polynomial algorithm so i can bench it against an opencl implementation, but i can't seem to get malloc to work. When I run the program it allocates a bunch of stuff, checks some things, then sends the size/2 to the algorithm. Then when I hit the malloc line again it spits out this: malloc.c:3096: sYSMALLOc: Assertion `(old_top == (((mbinptr) (((char *) &((av)-bins[((1) - 1) * 2])) - __builtin_offsetof (struct malloc_chunk, fd)))) && old_size == 0) || ((unsigned long) (old_size) = (unsigned long)((((__builtin_offsetof (struct malloc_chunk, fd_nextsize))+((2 * (sizeof(size_t))) - 1)) & ~((2 * (sizeof(size_t))) - 1))) && ((old_top)-size & 0x1) && ((unsigned long)old_end & pagemask) == 0)' failed. Aborted The line in question is: int *out, .....other vars....; out = (int *)malloc(sizeof(int) * size * 2); I have checked size with fprintf and it is a positive int (usually 50 at that point). I have tried calling malloc with a plain number as well and i still get the error. I'm just stumped at what's going on, and nothing from google that I have found so far has been too helpful. Any ideas what's going on? I'm trying to figure out how to compile a newer GCC in case it's a compiler error, but i really doubt it.

• How do you find a functions virtual call address in assembly?

  - by Daniel

  I've googled around but i'm not sure i am asking the right question or not and i couldn't find much regardless, perhaps a link would be helpful. I made a c++ program that shows a message box, then I opened it up with Ollydbg and went to the part where it calls MessageBoxW. The call address of MessageBoxW changes each time i run the app as windows is updating my Imports table to have the correct address of MessageBoxW. So my question is how do i find the virtual addres of MessageBoxW to my imports table and also how can i use this in ollydbg? Basically I'm trying to make a code cave in assembly to call MessageBoxW again. I got fairly close once by searching the executable with a hex editor and found the position of the call, and I think I found the virtual address. But when i call that virtual address in olly and saved it to the executable, the next time i opened it the call was replaced with a bunch of DB xyz (which looked like the virtual address but why did the call get removed? Sorry if my terminology is off as i'm new to this so i'm not quite sure what to call things.

• Sudden issues reading uncompressed video using opencv

  - by JohnSavage

  I have been using a particular pipeline to process video using opencv to encode uncompressed video (fourcc = 0), and opencv python bindings to then open and work on these files. This has been working fine for me on OpenCV 2.3.1a on Ubuntu 11.10 until just a few days ago. For some reason it currently is only allowing me to read the first frame of a given file the first time I open that file. Further frames are not read, and once I touch the file once with my program, it then cannot even read the first frame. More detail: I created the uncompressed video files as follows: out_video.open(out_vid_name, 0, // FOURCC = 0 means record raw fps, Size(640, 480)) Again, these videos worked fine for me until about a week ago. Now, when I try to open one of these I get the following message (from what I think is ffmpeg): Processing video.avi Using network protocols without global network initialization. Please use avformat_network_init(), this will become mandatory later. [avi @ 0x29251e0] parser not found for codec rawvideo, packets or times may be invalid. It reads and displays the first frame fine, but then fails to read the next frame. Then, when I try to run my code on the same video, the capture still opens with the same message as above. However, it cannot even read the very first frame. Here is the code to open the capture: self.capture = cv2.VideoCapture(filename) if not self.capture.isOpened() print "Error: could not open capture" sys.exit() Again, this part is passed without any issue, but then the break happens at: success, rgb = self.capture.read() if not success: print "error: could not read frame" return False This part breaks at the second frame on the first run of the video file, and then on the first frame on subsequent runs. I really don't know where to even begin debugging this. Please help!

• problem when trying to empty a stack in c

  - by frx08

  Hi all, (probably it's a stupid thing but) I have a problem with a stack implementation in C language, when I try to empty it, the function to empty the stack does an infinite loop.. the top of the stack is never null. where I commit an error? thanks bye! #include <stdio.h> #include <stdlib.h> typedef struct stack{ size_t a; struct stack *next; } stackPos; typedef stackPos *ptr; void push(ptr *top, size_t a){ ptr temp; temp = malloc(sizeof(stackPos)); temp->a = a; temp->next = *top; *top = temp; } void freeStack(ptr *top){ ptr temp = *top; while(*top!=NULL){ //the program does an infinite loop *top = temp->next; free(temp); } } int main(){ ptr top = NULL; push(&top, 4); push(&top, 8); //down here the problem freeStack(&top); return 0; }
