  • Bugs in Excel's ActiveX combo boxes?

    - by k.robinson
    I have noticed that I get all sorts of annoying errors when: I have ActiveX comboboxes on a worksheet (not an excel form) The comboboxes have event code linked to them (eg, onchange events) I use their listfillrange or linkedcell properties (clearing these properties seems to alleviate a lot of problems) (Not sure if this is connected) but there is data validation on the targeted linkedcell. I program a fairly complex excel application that does a ton of event handling and uses a lot of controls. Over the months, I have been trying to deal with a variety of bugs dealing with those combo boxes. I can't recall all the details of each instance now, but these bugs tend to involve pointing the listfillrange and linkedcell properties at named ranges, and often have to do with the combo box events triggering at inappropriate times (such as when application.enableevents = false). These problems seemed to grow bigger in Excel 2007, so that I had to give up on these combo boxes entirely (I now use combo boxes contained in user forms, rather than directly on the sheets). Has anyone else seen similar problems? If so, was there a graceful solution? I have looked around with Google and so far haven't spotted anyone with similar issues. Some of the symptoms I end up seeing are: Excel crashing when I start up (involves combobox_onchange, listfillrange-named range on another different sheet, and workbook_open interactions). (note, I also had some data validation on the the linked cells in case a user edited them directly.) Excel rendering bugs (usually when the combo box changes, some cells from another sheet get randomly drawn over the top of the current sheet) Sometimes it involves the screen flashing entirely to another sheet for a moment. Excel losing its mind (or rather, the call stack) (related to the first bullet point). Sometimes when a function modifies a property of the comboboxes, the combobox onchange event fires, but it never returns control to the function that caused the change in the first place. The combobox_onchange events are triggered even when application.enableevents = false. Events firing when they shouldn't (I posted another question on stack overflow related to this). At this point, I am fairly convinced that ActiveX comboboxes are evil incarnate and not worth the trouble. I have switched to including these comboboxes inside a userform module instead. I would rather inconvenience users with popup forms than random visual artifacts and crashing (with data loss).

  • What is in your Mathematica tool bag?

    - by Timo
    We all know that Mathematica is great, but it also often lacks critical functionality. What kind of external packages / tools / resources do you use with Mathematica? I'll edit (and invite anyone else to do so too) this main post to include resources which are focused on general applicability in scientific research and which as many people as possible will find useful. Feel free to contribute anything, even small code snippets (as I did below for a timing routine). Also, undocumented and useful features in Mathematica 7 and beyond you found yourself, or dug up from some paper/site are most welcome. Please include a short description or comment on why something is great or what utility it provides. If you link to books on Amazon with affiliate links please mention it, e.g., by putting your name after the link. Packages: LevelScheme is a package that greatly expands Mathematica's capability to produce good looking plots. I use it if not for anything else then for the much, much improved control over frame/axes ticks. David Park's Presentation Package ($50 - no charge for updates) Tools: MASH is Daniel Reeves's excellent perl script essentially providing scripting support for Mathematica 7. (This is finally built in as of Mathematica 8 with the -script option.) Resources: Wolfram's own repository MathSource has a lot of useful if narrow notebooks for various applications. Also check out the other sections such as Current Documentation, Courseware for lectures, and Demos for, well, demos. Books: Mathematica programming: an advanced introduction by Leonid Shifrin (web, pdf) is a must read if you want to do anything more than For loops in Mathematica. Quantum Methods with Mathematica by James F. Feagin (amazon) The Mathematica Book by Stephen Wolfram (amazon) (web) Schaum's Outline (amazon) Mathematica in Action by Stan Wagon (amazon) - 600 pages of neat examples and goes up to Mathematica version 7. Visualization techniques are especially good, you can see some of them on the author's Demonstrations Page. Mathematica Programming Fundamentals by Richard Gaylord (pdf) - A good concise introduction to most of what you need to know about Mathematica programming.

  • How can I do something ~after~ an event has fired in C#?

    - by Siracuse
    I'm using the following project to handle global keyboard and mouse hooking in my C# application. This project is basically a wrapper around the Win API call SetWindowsHookEx using either the WH_MOUSE_LL or WH_KEYBOARD_LL constants. It also manages certain state and generally makes this kind of hooking pretty pain free. I'm using this for a mouse gesture recognition software I'm working on. Basically, I have it setup so it detects when a global hotkey is pressed down (say CTRL), then the user moves the mouse in the shape of a pre-defined gesture and then releases global hotkey. The event for the KeyDown is processed and tells my program to start recording the mouse locations until it receives the KeyUp event. This is working fine and it allows an easy way for users to enter a mouse-gesture mode. Once the KeyUp event fires and it detects the appropriate gesture, it is suppose to send certain keystrokes to the active window that the user has defined for that particular gesture they just drew. I'm using the SendKeys.Send/SendWait methods to send output to the current window. My problem is this: When the user releases their global hotkey (say CTRL), it fires the KeyUp event. My program takes its recorded mouse points and detects the relevant gesture and attempts to send the correct input via SendKeys. However, because all of this is in the KeyUp event, that global hotkey hasn't finished being processed. So, for example if I defined a gesture to send the key "A" when it is detected, and my global hotkey is CTRL, when it is detected SendKeys will send "A" but while CTRL is still "down". So, instead of just sending A, I'm getting CTRL-A. So, in this example, instead of physically sending the single character "A" it is selecting-all via the CTRL-A shortcut. Even though the user has released the CTRL (global hotkey), it is still being considered down by the system. Once my KeyUp event fires, how can I have my program wait some period of time or for some event so I can be sure that the global hotkey is truly no longer being registered by the system, and only then sending the correct input via SendKeys?

  • UIViewAnimation done by a UIViewController belonging to a UINavigationController?

    - by RickiG
    Hi I have an UINavigationController which the user navigates with. When pushing a specific UIViewController onto the navigation stack, a "settings" button appear in the navigationBar. When the user clicks this button I would like to flip the current view/controller, i.e. everything on screen, including the navigationBar, over to a settings view. So I have a SettingsViewController which I would like to flip to from my CurrentViewController that lives on a navigationController stack. I get all kinds of strange behavior trying to do this, the UIViews belonging to the SettingsViewController will start to animate, sliding into place, the navigationButtons moves around, nothing acts as I would think. -(void)settingsHandler { SettingViewController *settingsView = [[SettingViewController alloc] init]; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:1.0]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.navigationController.view cache:YES]; [self.navigationController.view addSubview:settingsView.view]; [UIView commitAnimations]; } The above results in the views flipping correctly, but the subviews of the SettingsViewController are all positioned in (0, 0) and after the transition, they 'snap' into place? Is it because I instantiate and add my subviews in viewDidLoad, like this? - (void)viewDidLoad { UIImageView *imageBg = [[UIImageView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 460.0f)]; [imageBg setImage:[UIImage imageNamed:@"background.png"]]; [self.view addSubview:imageBg]; [imageBg release]; SettingsSubview *switchView = [[SettingsSubview alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 460.0f)]; [self.view addSubview:switchView]; [switchView release]; [super viewDidLoad]; } 1: How should I correctly do the "flip" transition, from within the UIViewController in the UINavigationController, to a new UIViewController and subsequently from the new UIViewController and back to the "original" UIViewController residing on the UINavigationControllers stack? 2: Should I use a different approach, than the "viewDidLoad" method, when instantiating and adding subviews to a UIViewController? -question 2 is more of a "best practice" thing. I have seen different ways of doing it and I am having trouble either finding or understanding the life-cycle documentation and the different threads and posts on the subject. I am missing the "best practice" examples. Thank You very much for any help given:)

  • Sharing a UIView between UIViewControllers in a UITabBarController

    - by Wireless Designs
    Hi all - I have a UIScrollView that houses a gallery of images the user can scroll through. This view needs to be visible on each of three separate UIViewControllers that are housed within a UITabBarController. Right now, I have three separate UIScrollView instances in the UITabBarController subclass, and the controller manages keeping the three synchronized (when a user scrolls the one they can see, programmatically scrolling the other two to match, etc.), which is not ideal. I would like to know if there is a way to work with only ONE instance of the UIScrollView, but have it show up only in the UIViewController that the user is currently interacting with. This would completely eliminate all the synchronization code. Here is basically what I have now in the UITabBarController (which is where all this is currently managed): @interface ScrollerTabBarController : UITabBarController { FirstViewController *firstView; SecondViewController *secondView; ThirdViewController *thirdView; UIScrollView *scrollerOne; UIScrollView *scrollerTwo; UIScrollView *scrollerThree; } @property (nonatomic,retain) IBOutlet FirstViewController *firstView; @property (nonatomic,retain) IBOutlet SecondViewController *secondView; @property (nonatomic,retain) IBOutlet ThirdViewController *thirdView; @property (nonatomic,retain) IBOutlet UIScrollView *scrollerOne; @property (nonatomic,retain) IBOutlet UIScrollView *scrollerTwo; @property (nonatomic,retain) IBOutlet UIScrollView *scrollerThree; @end @implementation ScrollerTabBarController - (void)layoutScroller:(UIScrollView *)scroller {} - (void)scrollToMatch:(UIScrollView *)scroller {} - (void)viewDidLoad { [self layoutScroller:scrollerOne]; [self layoutScroller:scrollerTwo]; [self layoutScroller:scrollerThree]; [scrollerOne setDelegate:self]; [scrollerTwo setDelegate:self]; [scrollerThree setDelegate:self]; [firstView setGallery:scrollerOne]; [secondView setGallery:scrollerTwo]; [thirdView setGallery:scrollerThree]; } - (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView { [self scrollToMatch:scrollView]; } @end The UITabBarController gets notified (as the scroll view's delegate) when the user scrolls one of the instances, and then calls methods like scrollToMatch: to sync up the other two with the user's choice. Is there something that can be done, using a many-to-one relationship on IBOutlet or something like that, to narrow this down to one instance so I'm not having to manage three scroll views? I tried keeping a single instance and moving the pointer from one view to the next using the UITabBarControllerDelegate methods (calling setGallery:nil on the current and setGallery:scrollerOne on the next each time it changed), but the scroller never moved to the other tabs. Thanks in advance!

  • Android - Key Dispatching Timed Out

    - by Donal Rafferty
    In my Android application I am getting a very strange crash, when I press a button (Image) on my UI the entire application freezes and after a couple of seconds I getthe dreaded force close dialog appearing. Here is what gets printed in the log: WARN/WindowManager(88): Key dispatching timed out sending to package name/Activity WARN/WindowManager(88): Dispatch state: {{KeyEvent{action=1 code=5 repeat=0 meta=0 scancode=231 mFlags=8} to Window{432bafa0 com.android.launcher/com.android.launcher.Launcher paused=false} @ 1281611789339 lw=Window{432bafa0 com.android.launcher/com.android.launcher.Launcher paused=false} lb=android.os.BinderProxy@431ee8e8 fin=false gfw=true ed=true tts=0 wf=false fp=false mcf=Window{4335fc58 package name/Activity paused=false}}} WARN/WindowManager(88): Current state: {{null to Window{4335fc58 package name/Activity paused=false} @ 1281611821193 lw=Window{4335fc58 package name/Activity paused=false} lb=android.os.BinderProxy@434c9bd0 fin=false gfw=true ed=true tts=0 wf=false fp=false mcf=Window{4335fc58 package name/Activity paused=false}}} INFO/ActivityManager(88): ANR in process: package name (last in package name) INFO/ActivityManager(88): Annotation: keyDispatchingTimedOut INFO/ActivityManager(88): CPU usage: INFO/ActivityManager(88): Load: 5.18 / 5.1 / 4.75 INFO/ActivityManager(88): CPU usage from 7373ms to 1195ms ago: INFO/ActivityManager(88): package name: 6% = 1% user + 5% kernel / faults: 7 minor INFO/ActivityManager(88): system_server: 5% = 4% user + 1% kernel / faults: 27 minor INFO/ActivityManager(88): tiwlan_wifi_wq: 3% = 0% user + 3% kernel INFO/ActivityManager(88): mediaserver: 0% = 0% user + 0% kernel INFO/ActivityManager(88): logcat: 0% = 0% user + 0% kernel INFO/ActivityManager(88): TOTAL: 12% = 5% user + 6% kernel + 0% softirq INFO/ActivityManager(88): Removing old ANR trace file from /data/anr/traces.txt INFO/Process(88): Sending signal.

It seems unlikely as several other buttons do the same without issue. How about the native layer? Could some code I've built with the NDK be causing the issue? Any other ideas as to what the cause of the issue might be?

  • Question About Example In Robert C Martin's _Clean Code_

    - by Jonah
    This is a question about the concept of a function doing only one thing. It won't make sense without some relevant passages for context, so I'll quote them here. They appear on pgs 37-38: To say this differently, we want to be able to read the program as though it were a set of TO paragraphs, each of which is describing the current level of abstraction and referencing subsequent TO paragraphs at the next level down. To include the setups and teardowns, we include setups, then we include the test page content, and then we include the teardowns. To include the setups, we include the suite setup if this is a suite, then we include the regular setup. It turns out to be very dif?cult for programmers to learn to follow this rule and write functions that stay at a single level of abstraction. But learning this trick is also very important. It is the key to keeping functions short and making sure they do “one thing.” Making the code read like a top-down set of TO paragraphs is an effective technique for keeping the abstraction level consistent. He then gives the following example of poor code: public Money calculatePay(Employee e) throws InvalidEmployeeType { switch (e.type) { case COMMISSIONED: return calculateCommissionedPay(e); case HOURLY: return calculateHourlyPay(e); case SALARIED: return calculateSalariedPay(e); default: throw new InvalidEmployeeType(e.type); } } and explains the problems with it as follows: There are several problems with this function. First, it’s large, and when new employee types are added, it will grow. Second, it very clearly does more than one thing. Third, it violates the Single Responsibility Principle7 (SRP) because there is more than one reason for it to change. Fourth, it violates the Open Closed Principle8 (OCP) because it must change whenever new types are added. Now my questions. To begin, it's clear to me how it violates the OCP, and it's clear to me that this alone makes it poor design. However, I am trying to understand each principle, and it's not clear to me how SRP applies. Specifically, the only reason I can imagine for this method to change is the addition of new employee types. There is only one "axis of change." If details of the calculation needed to change, this would only affect the submethods like "calculateHourlyPay()" Also, while in one sense it is obviously doing 3 things, those three things are all at the same level of abstraction, and can all be put into a TO paragraph no different from the example one: TO calculate pay for an employee, we calculate commissioned pay if the employee is commissioned, hourly pay if he is hourly, etc. So aside from its violation of the OCP, this code seems to conform to Martin's other requirements of clean code, even though he's arguing it does not. Can someone please explain what I am missing? Thanks.

  • "Bad binary signature" in ASP.NET MVC application

    - by David M
    We are getting the error above on some pages of an ASP.NET MVC application when it is deployed to a 64 bit Windows 2008 server box. It works fine on our development machines, though these are 32 bit XP. Just wondered if anyone had encountered this before, and has any suggestions? Details as follows: Bad binary signature. (Exception from HRESULT: 0x80131192) Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Runtime.InteropServices.COMException: Bad binary signature. (Exception from HRESULT: 0x80131192) All projects are set to compile for Any CPU, and are compiled in Release mode. The ASP.NET site is precompiled, and the precompiled build is on a 64 bit Windows 2008 TeamCity build agent. Thanks in advance. EDIT We're still plagued by this. I have looked at all the binaries in the website's bin directory using corflags.exe. None has the 32BIT flag set, and all have a CorFlags value of 9 except for Antlr3.Runtime.dll which has a value of 1. The problem only affects certain pages, and it seems to be those which use FluentValidation (including FluentValidation.Mvc and FluentValidation.xValIntegration assemblies). None of these shows anything out of the ordinary when inspected with corflags.exe, and there are no odd looking dependencies revealed by ildasm. When built locally (32 bit Windows XP) the site deploys and runs fine. When built on the build agents (64 bit Windows 2008 Server) the site displays these errors. The site runs in Integrated Pipeline mode, and is not set to 32 bit. The stack trace is: [COMException (0x80131192): Bad binary signature.

  • HLSL, Program pixel shader with different Texture2D downscaling algorithms

    I'm trying to port some image interpolation algorithms into HLSL code, for now i got: float2 texSize; float scale; int method; sampler TextureSampler : register(s0); float4 PixelShader(float4 color : COLOR0, float2 texCoord : TEXCOORD0) : COLOR0 { float2 newTexSize = texSize * scale; float4 tex2; if(texCoord[0] * texSize[0] > newTexSize[0] || texCoord[1] * texSize[1] > newTexSize[1]) { tex2 = float4( 0, 0, 0, 0 ); } else { if (method == 0) { tex2 = tex2D(TextureSampler, float2(texCoord[0]/scale, texCoord[1]/scale)); } else { float2 step = float2(1/texSize[0], 1/texSize[1]); float4 px1 = tex2D(TextureSampler, float2(texCoord[0]/scale-step[0], texCoord[1]/scale-step[1])); float4 px2 = tex2D(TextureSampler, float2(texCoord[0]/scale , texCoord[1]/scale-step[1])); float4 px3 = tex2D(TextureSampler, float2(texCoord[0]/scale+step[0], texCoord[1]/scale-step[1])); float4 px4 = tex2D(TextureSampler, float2(texCoord[0]/scale-step[0], texCoord[1]/scale )); float4 px5 = tex2D(TextureSampler, float2(texCoord[0]/scale+step[0], texCoord[1]/scale )); float4 px6 = tex2D(TextureSampler, float2(texCoord[0]/scale-step[0], texCoord[1]/scale+step[1])); float4 px7 = tex2D(TextureSampler, float2(texCoord[0]/scale , texCoord[1]/scale+step[1])); float4 px8 = tex2D(TextureSampler, float2(texCoord[0]/scale+step[0], texCoord[1]/scale+step[1])); tex2 = (px1+px2+px3+px4+px5+px6+px7+px8)/8; tex2.a = 1; } } return tex2; } technique Resample { pass Pass1 { PixelShader = compile ps_2_0 PixelShader(); } } The problem is that programming pixel shader requires different approach because we don't have the control of current position, only the 'inner' part of actual loop through pixels. I've been googling for about whole day and found none open source library with scaling algoriths used in loop. Is there such library from wich i could port some methods? I found http://www.codeproject.com/KB/GDI-plus/imgresizoutperfgdiplus.aspx but I really don't understand His approach to the problem, and porting it will be a pain in the ... Wikipedia tells a matematic approach. So my question is: Where can I find easy-to-port graphic open source library wich includes simple scaling algorithms? Of course if such library even exists :)

  • JS onclick triggers wrong object

    - by Clemens Prerovsky
    Hi guys, what I'm trying to do here is to associate a DOM object with an instance of a JS object, which will provide some meaningfol methods later on ;) At this point I just want to handle my JS object the click event, whilst keeping it's references intact. <?xml version="1.0" encoding="ISO-8859-1" ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" /> <title>Insert title here</title> <script type="text/javascript"> // my object, which will hold a reference to a single DOM object obj = function(domobj) { this.o = domobj; my = this; var ref = my.click; this.o.onclick = ref; } // my objects click function obj.prototype.click = function() { alert(my.o.innerHTML); } // create objects with references $(document).ready(function() { o1 = new obj(document.getElementById('b1')); o2 = new obj(document.getElementById('b2')); }); </script> </head> <body> <button id="b1">button 1</button> <button id="b2">button 2</button> </body> </html> Expected result: when clicking on button 1, the text "button 1" should be alerted. Current result: when clicking button 1, the text "button 2" is alerted. What I found out so far is that the wrong instance of obj is triggered from the click event, even though o1 and o2 maintain correct references to their corresponding DOM object. Any ideas how to solve this? Thanks for your help! Best regards, Clemens

  • Javascript Noob: How to emulate slideshow on front page by automatically cycling through existing ho

    - by Zildjoms
    hey everyone. hope you could help me out am working on this website and i've finished all the hover effects i like - they're exactly how i want them to be: http://s5ent.brinkster.net/beta3.asp - try hovering over the four links and you'll see a very simple fade effect at work, which degrades into a regular css hover without javascript. what i plan to do is to make the page look like it had a fancy slideshow going on upon loading and while idle, and i wanted to achieve that by capitalizing on the existing hover styling/behavior of the main page links instead of using another script to create the effect from scratch. to do this i imagined i'll need a script that emulates a hover action on each link at regular time intervals once the page has loaded, starting from left to right (footcare, lawn & equipment, about us, contact us), looping through all 4 links indefinitely (footcare, lawn & equipment, about us, contact us, footcare, lawn& equipment, etc.) but pauses when any of them have been actually hovered over by a viewer and resumes from wherever the user left off upon mouseout. hope you get my drift... i also want to achieve this without unnecessarily disrupting the current html. so i guess everything will have to be done by scripting as much as possible.. i'm very new to javascript and jquery. as you can see at s5ent.brinkster.net/beta3.1-autohover.asp, the following script i made works wrong: it hovers-on all of them at the same time and doesn't hover-out anymore. when you try to actually hover into and out of each link the link just comes back on: <script type="text/javascript"> $(document).ready(function () { var speed = 5000; var run = setInterval('rotate()', speed); }); function rotate() { $('.lilevel1 a').each(function(i) { $(this).mouseover(); }); } </script> it's just gross. aside from the fact that this last bit of script isn't even working in ie. could you please help me make this thing happen? that'd be really sweet, guys. i know there are tonsa geniuses out there who could whip this up in no time. or if you have a better way to go about it by all means kindly lemme know. thanks guys, hope you're all havin a blast.

  • android spinning image

    - by user270811
    hi, i am trying to create two spinning wheels, as in pulleys, so everytime the attached rope moves, the two pulleys will rotate. i have tried two approaches: 1) use Matrix.postRotate within the onDraw() method of the View class, which calls the following: private void drawSpinningWheel(Canvas canvas) { try { canvas.save(); Bitmap bitmapOrg = null; int iDrawable = R.drawable.spinning_button; bitmapOrg = BitmapFactory.decodeResource(getResources(), iDrawable); if(bitmapOrg != null) { int width = bitmapOrg.getWidth(); int height = bitmapOrg.getHeight(); int newWidth = 24; int newHeight = 24; // calculate the scale - in this case = 0.4f float scaleWidth = ((float) newWidth) / width; float scaleHeight = ((float) newHeight) / height; // createa matrix for the manipulation Matrix matrix = new Matrix(); // resize the bit map matrix.postScale(scaleWidth, scaleHeight); matrix.postRotate((float) mDegrees++); Bitmap resizedBitmap = Bitmap.createBitmap(bitmapOrg, 0, 0, width, height, matrix, true); canvas.drawBitmap(resizedBitmap, matrix, null); } canvas.restore(); } catch(Exception e) { Log.e(TAG + "drawSpinningWheel", e.getMessage()); } } but it seems like the image not only spins but rotates around another axis 2) use SurfaceView and a separate thread, in the run() call this: private void doDraw(Canvas canvas) { // Draw the background image. Operations on the Canvas accumulate // so this is like clearing the screen. canvas.drawBitmap(mBackgroundImage, 0, 0, null); int yTop = mCanvasHeight - ((int) mY + mSpinningWheelImageHeight / 2); int xLeft = (int) mX - mSpinningWheelImageWidth / 2; ... // Draw the ship with its current rotation canvas.save(); canvas.rotate((float) mHeading++, (float) mX, mCanvasHeight - (float) mY); mSpinningWheelImage.setBounds(xLeft, yTop, xLeft + mSpinningWheelImageWidth, yTop + mSpinningWheelImageHeight); mSpinningWheelImage.draw(canvas); canvas.restore(); } i get the spinning to work but i can't add another spinning wheel. i even tried to create another thread for the second spinning wheel, only one shows up. can someone point me in the right direction? thanks.

  • Handling Errors from HttpWebRequest.GetResponse

    - by Jason
    Hey experts - I'm having a ridiculous time trying to get an SMS API working (ZeepMobile, if you're interested) with .NET... I've been around .NET for a few years, but with all this social networking and API stuff, I need to get into the HttpWebRequest a bit. I'm new at it, but not completely new; I was able to hook up my site to Twitter without too much fuss (ie, I was able to modify someone's code to work for me). Anyways, the way their API works is to send an SMS message, you send them a POST and they respond back to you. I can send it just fine, but every time I do, rather than echo back something helpful to figure out what the error is, I get the Yellow Error Page Of Death (YEPOD) saying something to the effect of "The remote server returned an error: (400) Bad Request." This occurs on my line: '...creation of httpwebrequest here...' Dim myWebResponse As WebResponse myWebResponse = request.GetResponse() '<--- error line Is there any way to simply receive the error from the server rather than have the webserver throw an exception and give me the YEPOD? Or better yet, can anyone post a working example of their Zeep code? :) Thanks! EDIT: Here's my whole code block: Public Shared Function SendTextMessage(ByVal username As String, _ ByVal txt As String) As String Dim content As String = "user_id=" + _ username + "&body=" + Current.Server.UrlEncode(txt) Dim httpDate As String = DateTime.Now.ToString("r") Dim canonicalString As String = API_KEY & httpDate & content Dim encoding As New System.Text.UTF8Encoding Dim hmacSha As New HMACSHA1(encoding.GetBytes(SECRET_ACCESS_KEY)) Dim hash() As Byte = hmacSha.ComputeHash(encoding.GetBytes(canonicalString)) Dim b64 As String = Convert.ToBase64String(hash) 'connect with zeep' Dim request As HttpWebRequest = CType(WebRequest.Create(_ "https://api.zeepmobile.com/messaging/2008-07-14/send_message"), HttpWebRequest) request.Method = "POST" request.ServicePoint.Expect100Continue = False ' set the authorization levels' request.Headers.Add("Authorization", "Zeep " & API_KEY & ":" & b64) request.ContentType = "application/x-www-form-urlencoded" request.ContentLength = content.Length ' set up and write to stream' Dim reqStream As New StreamWriter(request.GetRequestStream()) reqStream.Write(content) reqStream.Close() Dim msg As String = "" msg = reqStream.ToString Dim myWebResponse As WebResponse Dim myResponseStream As Stream Dim myStreamReader As StreamReader myWebResponse = request.GetResponse() myResponseStream = myWebResponse.GetResponseStream() myStreamReader = New StreamReader(myResponseStream) msg = myStreamReader.ReadToEnd() myStreamReader.Close() myResponseStream.Close() ' Close the WebResponse' myWebResponse.Close() Return msg End Function

  • General advice and guidelines on how to properly override object.GetHashCode()

    - by Svish
    According to MSDN, a hash function must have the following properties: If two objects compare as equal, the GetHashCode method for each object must return the same value. However, if two objects do not compare as equal, the GetHashCode methods for the two object do not have to return different values. The GetHashCode method for an object must consistently return the same hash code as long as there is no modification to the object state that determines the return value of the object's Equals method. Note that this is true only for the current execution of an application, and that a different hash code can be returned if the application is run again. For the best performance, a hash function must generate a random distribution for all input. I keep finding myself in the following scenario: I have created a class, implemented IEquatable<T> and overridden object.Equals(object). MSDN states that: Types that override Equals must also override GetHashCode ; otherwise, Hashtable might not work correctly. And then it usually stops up a bit for me. Because, how do you properly override object.GetHashCode()? Never really know where to start, and it seems to be a lot of pitfalls. Here at StackOverflow, there are quite a few questions related to GetHashCode overriding, but most of them seems to be on quite particular cases and specific issues. So, therefore I would like to get a good compilation here. An overview with general advice and guidelines. What to do, what not to do, common pitfalls, where to start, etc. I would like it to be especially directed at C#, but I would think it will work kind of the same way for other .NET languages as well(?). I think maybe the best way is to create one answer per topic with a quick and short answer first (close to one-liner if at all possible), then maybe some more information and end with related questions, discussions, blog posts, etc., if there are any. I can then create one post as the accepted answer (to get it on top) with just a "table of contents". Try to keep it short and concise. And don't just link to other questions and blog posts. Try to take the essence of them and then rather link to source (especially since the source could disappear. Also, please try to edit and improve answers instead of created lots of very similar ones. I am not a very good technical writer, but I will at least try to format answers so they look alike, create the table of contents, etc. I will also try to search up some of the related questions here at SO that answers parts of these and maybe pull out the essence of the ones I can manage. But since I am not very stable on this topic, I will try to stay away for the most part :p

  • Team Foundation Server Setup/Access

    - by Angel Brighteyes
    What I need: A TFS 2010 Setup that allows 2 application developers to access the TFS from remote locations. How it is setup: Server 2008 Standard 2g Ram 300g HD space SharePoint Server 2007, using SQL Server 2005 SQL Server 2008 Standard Team Foundation Server 2010 IIS 7 Sharepoint Bindings: TFS.DynAccount.Me:80; TFS:80 TFS Bindings: TFS.DynAccount.Me:8080; TFS:8080 Using DynDNS service to account for the dynamic ip address being used, this is a requirement for the moment until I can get a better isp package. Access using Local Accounts Server is not setup on a domain, or as a domain. Consequently I did not setup AD services. Problem: When logged into TFS using my credentials TFS\AdminUser through the DynDNS account TFS.DynAccount.Me I recieve the 'Red X of Death' on the Documents and Reports folder. When logged into the TFS through the local peer to peer network using the same credentials TFS\AdminUser I do not receive the 'Red X of Death' problem. Further Troubleshooting: When users 'Right Click' the 'TeamProject1' Click 'Show Project Portal' it tries to take them to http://TFS:8080 instead of http://TFS.DynAccount.Me:8080, which doing further research I am assuming that it is because team foundation server was setup with a local name of TFS instead of 'TFS.DynAccount.Me' as specified here in Visual Studio Magazines: The Red X of Death. Users can Access the Team Portal for SharePoint via http://TFS.DynAccount.Me/TeamCollection/TeamProject so it is not like we are dead in the water or anything. However, as most employees/staff are prone to do, they have expressed a great distaste for having to do it this way and just be patient until the current project is finished since we are under a very strict deadline. Is there a way to set this up differently, or change some settings someplace, reinstall it, point a CName record for our domain website to the DynAccount (e.g. TFS.OurDomain.com points to TFS.DynAccount.Me, which consequently does allow access to the http site without issues), or something. I really don't feel like after all the time and effort I have spent into, first the cost, second the bloody install, third learning SharePoint well enough, fourth the hours into days spent on this, fifth more troubleshooting, sixth employee headaches to just let it lay where it is at. I figure in my spare/off time I would keep trying to get this to work. So I really appreciate any help any one can give me. I know this is probably something really stupid simple that I will 'Face Palm' over, but at the moment the stress and frustration just has me beat. Thank you again, this community has always been a great help.

  • C# Monte Carlo Incremental Risk Calculation optimisation, random numbers, parallel execution

    - by m3ntat
    My current task is to optimise a Monte Carlo Simulation that calculates Capital Adequacy figures by region for a set of Obligors. It is running about 10 x too slow for where it will need to be in production and number or daily runs required. Additionally the granularity of the result figures will need to be improved down to desk possibly book level at some stage, the code I've been given is basically a prototype which is used by business units in a semi production capacity. The application is currently single threaded so I'll need to make it multi-threaded, may look at System.Threading.ThreadPool or the Microsoft Parallel Extensions library but I'm constrained to .NET 2 on the server at this bank so I may have to consider this guy's port, http://www.codeproject.com/KB/cs/aforge_parallel.aspx. I am trying my best to get them to upgrade to .NET 3.5 SP1 but it's a major exercise in an organisation of this size and might not be possible in my contract time frames. I've profiled the application using the trial of dotTrace (http://www.jetbrains.com/profiler). What other good profilers exist? Free ones? A lot of the execution time is spent generating uniform random numbers and then translating this to a normally distributed random number. They are using a C# Mersenne twister implementation. I am not sure where they got it or if it's the best way to go about this (or best implementation) to generate the uniform random numbers. Then this is translated to a normally distributed version for use in the calculation (I haven't delved into the translation code yet). Also what is the experience using the following? http://quantlib.org http://www.qlnet.org (C# port of quantlib) or http://www.boost.org Any alternatives you know of? I'm a C# developer so would prefer C#, but a wrapper to C++ shouldn't be a problem, should it? Maybe even faster leveraging the C++ implementations. I am thinking some of these libraries will have the fastest method to directly generate normally distributed random numbers, without the translation step. Also they may have some other functions that will be helpful in the subsequent calculations. Also the computer this is on is a quad core Opteron 275, 8 GB memory but Windows Server 2003 Enterprise 32 bit. Should I advise them to upgrade to a 64 bit OS? Any links to articles supporting this decision would really be appreciated. Anyway, any advice and help you may have is really appreciated.

  • Clickable widgets in android

    - by Leif Andersen
    The developer documentation has seemed to have failed me here. I can create a static widget without thinking, I can even create a widget like the analogue clock widget that will update itself, however, I can not for the life of me figure out how to create a widget that reacts to when a user clicks on it. Here is the best code sample that the developer documentation gives to what a widget activity should contain (the only other hint being the API demos, which only creates a static widget): public class ExampleAppWidgetProvider extends AppWidgetProvider { public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { final int N = appWidgetIds.length; // Perform this loop procedure for each App Widget that belongs to this provider for (int i=0; i<N; i++) { int appWidgetId = appWidgetIds[i]; // Create an Intent to launch ExampleActivity Intent intent = new Intent(context, ExampleActivity.class); PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0); // Get the layout for the App Widget and attach an on-click listener to the button RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.appwidget_provider_layout); views.setOnClickPendingIntent(R.id.button, pendingIntent); // Tell the AppWidgetManager to perform an update on the current App Widget appWidgetManager.updateAppWidget(appWidgetId, views); } } } from: The Android Developer Documentation's Widget Page So, it looks like pending intent is called when the widget is clicked, which is based off of an intent (I'm not quite sure what the difference between an intent and a pending intent is), and the intent is for the ExampleActivity class. So I made my sample activity class a simple activity that when created, would create a mediaplayer object, and start it (it wouldn't ever release the object, so it would eventually crash, here is it's code: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); MediaPlayer mp = MediaPlayer.create(getApplicationContext(), R.raw.sound); mp.start(); } However, when I added the widget to the home screen, and clicked on it, nothing played, in fact, nothing played when I set the update timer to just a few hundred milliseconds (in the appwidget provider xml file). Furthermore, I set break points and found out that not only was it never reaching the activity, but no break points I set would ever get triggered. (I still haven't figured out why that is), however, logcat seemed to indicate that the activity class file was being run. So, is there anything I can do to get an appwidget to respond to a click? As the onClickPendingIntent() method is the closest I have found to a onClick type of method. Thank you very much.

  • Hooking DirectX EndScene from an injected DLL

    - by Etan
    I want to detour EndScene from an arbitrary DirectX 9 application to create a small overlay. As an example, you could take the frame counter overlay of FRAPS, which is shown in games when activated. I know the following methods to do this: Creating a new d3d9.dll, which is then copied to the games path. Since the current folder is searched first, before going to system32 etc., my modified DLL gets loaded, executing my additional code. Downside: You have to put it there before you start the game. Same as the first method, but replacing the DLL in system32 directly. Downside: You cannot add game specific code. You cannot exclude applications where you don't want your DLL to be loaded. Getting the EndScene offset directly from the DLL using tools like IDA Pro 4.9 Free. Since the DLL gets loaded as is, you can just add this offset to the DLL starting address, when it is mapped to the game, to get the actual offset, and then hook it. Downside: The offset is not the same on every system. Hooking Direct3DCreate9 to get the D3D9, then hooking D3D9-CreateDevice to get the device pointer, and then hooking Device-EndScene through the virtual table. Downside: The DLL cannot be injected, when the process is already running. You have to start the process with the CREATE_SUSPENDED flag to hook the initial Direct3DCreate9. Creating a new Device in a new window, as soon as the DLL gets injected. Then, getting the EndScene offset from this device and hooking it, resulting in a hook for the device which is used by the game. Downside: as of some information I have read, creating a second device may interfere with the existing device, and it may bug with windowed vs. fullscreen mode etc. Same as the third method. However, you'll do a pattern scan to get EndScene. Downside: doesn't look that reliable. How can I hook EndScene from an injected DLL, which may be loaded when the game is already running, without having to deal with different d3d9.dll's on other systems, and with a method which is reliable? How does FRAPS for example perform it's DirectX hooks? The DLL should not apply to all games, just to specific processes where I inject it via CreateRemoteThread.

  • Chaining IQueryables together

    - by Matt Greer
    I have a RIA Services based app that is using Entity Framework on the server side (possibly not relevant). In my real app, I can do something like this. EntityQuery<Status> query = statusContext.GetStatusesQuery().Where(s => s.Description.Contains("Foo")); Where statusContext is the client side subclass of DomainContext that RIA Services was kind enough to generate for me. The end result is an EntityQuery<Status> object who's Query property is an object that implements IQueryable and represents my where clause. The WebDomainClient is able to take this EntityQuery and not just give me back all of my Statuses but also filtered with my where clause. I am trying to implement this in a mock DomainClient. This MockDomainClient accepts an IQueryably<Entity> which it returns when asked for. But what if the user makes the query and includes the ad hoc additional query? How can I merge the two together? My MockDomainClient is (this is modeled after this blog post) ... public class MockDomainClient : LocalDomainClient { private IQueryable<Entity> _entities; public MockDomainClient(IQueryable<Entity> entities) { _entities = entities; } public override IQueryable<Entity> DoQuery(EntityQuery query) { if (query.Query == null) { return _entities; } // otherwise want the union of _entities and query.Query, query.Query is IQueryable // the below does not work and was a total shot in the dark: //return _entities.Union(query.Query.Cast<Entity>()); } } public abstract class LocalDomainClient : System.ServiceModel.DomainServices.Client.DomainClient { private SynchronizationContext _syncContext; protected LocalDomainClient() { _syncContext = SynchronizationContext.Current; } ... public abstract IQueryable<Entity> DoQuery(EntityQuery query); protected override IAsyncResult BeginQueryCore(EntityQuery query, AsyncCallback callback, object userState) { IQueryable<Entity> localQuery = DoQuery(query); LocalAsyncResult asyncResult = new LocalAsyncResult(callback, userState, localQuery); _syncContext.Post(o => (o as LocalAsyncResult).Complete(), asyncResult); return asyncResult; } ... }

  • How do i rotate a CALayer around a diagonal line?

    - by Mattias Wadman
    Hi. I'm trying to implement a flip animation to be used in board game like iPhone-application. The animation is supposed to look like a game piece that rotates and changes to the color of its back (kind of like an Reversi piece). I've managed to create an animation that flips the piece around its orthogonal axis, but when I try to flip it around a diagonal axis by changing the rotation around the z-axis the actual image also gets rotated (not surprisingly). Instead I would like to rotate the image "as is" around a diagonal axis. I have tried to change layer.sublayerTransform but with no success. Here is my current implementation. It works by doing a trick to resolve the issue of getting a mirrored image at the end of the animation. The solution is to not actually rotate the layer 180 degrees, instead it rotates it 90 degrees, changes image and then rotates it back. + (void)flipLayer:(CALayer *)layer toImage:(CGImageRef)image withAngle:(double)angle { const float duration = 0.5f; CAKeyframeAnimation *diag = [CAKeyframeAnimation animationWithKeyPath:@"transform.rotation.z"]; diag.duration = duration; diag.values = [NSArray arrayWithObjects: [NSNumber numberWithDouble:angle], [NSNumber numberWithDouble:0.0f], nil]; diag.keyTimes = [NSArray arrayWithObjects: [NSNumber numberWithDouble:0.0f], [NSNumber numberWithDouble:1.0f], nil]; diag.calculationMode = kCAAnimationDiscrete; CAKeyframeAnimation *flip = [CAKeyframeAnimation animationWithKeyPath:@"transform.rotation.y"]; flip.duration = duration; flip.values = [NSArray arrayWithObjects: [NSNumber numberWithDouble:0.0f], [NSNumber numberWithDouble:M_PI / 2], [NSNumber numberWithDouble:0.0f], nil]; flip.keyTimes = [NSArray arrayWithObjects: [NSNumber numberWithDouble:0.0f], [NSNumber numberWithDouble:0.5f], [NSNumber numberWithDouble:1.0f], nil]; flip.calculationMode = kCAAnimationLinear; CAKeyframeAnimation *replace = [CAKeyframeAnimation animationWithKeyPath:@"contents"]; replace.duration = duration / 2; replace.beginTime = duration / 2; replace.values = [NSArray arrayWithObjects:(id)image, nil]; replace.keyTimes = [NSArray arrayWithObjects: [NSNumber numberWithDouble:0.0f], nil]; replace.calculationMode = kCAAnimationDiscrete; CAAnimationGroup *group = [CAAnimationGroup animation]; group.removedOnCompletion = NO; group.duration = duration; group.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear]; group.animations = [NSArray arrayWithObjects:diag, flip, replace, nil]; group.fillMode = kCAFillModeForwards; [layer addAnimation:group forKey:nil]; }
