• SQL Server Conditional Split problem

  Don't know if anybody else has had this - In a dataflow task I added a conditional split that currently has two possible outcomes. Initially this was a straight choice. Later I added an "or" clause on the second leg thus expression1 || expression2 on which the second leg ceased working. After some mental anguish I deleted the component and then reimplemented it using identical logic and magically (or so it appears) it all worked. So, it appears the old tricks still apply... When I created the new component, I copied the old expressions to Notepad and then pasted them back in again, so your scenario is unlikely (though of course not impossible.) ...Show All

• Visual C++ STL Thread Safety

  So, I looked for STL thread safety, and there are only two hits:  One in Visual C++ Express Edition , and the other in Visual C# Language . Where's the best place to discuss MSVC 2005's STL thread safety -MM mmoo9154 wrote: For instance, it would be (fairly) trivial, and immensely useful if std::queue was safe to insert from one thread and extract from another without synchronization. Mixing synchronization with those containers would introduce a bucket of problems. It would make portable / semi-portable STL implementations a lot harder to maintain. How can one judge which synchronization approach is best fit for any use of say a queue While one user would like read ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Mouse Pointer not visible in Spacewar

  I managed to get the Spacewar game running after modifying the code by setting graphics.AllowMultiSampling to false. However, the Mouse pointer is not visible on the screen and I have no control to start the actual game play. Can somebody assist me Go to the “GamePadHelper.cs” file and uncomment this line. //#define USE_KEYBOARD Now you can use the A,B,S,W,D, and X keys. I got this information from http://www.xnaspot.com/Tutorial_GettingStarted.aspx which is really helpful. ...Show All

• SQL Server How to use coalesce function in derived column component?

  Hi all, You know the coalesce function is not offered in the derived column component. how can I use the coalesce function within the component And how can I use a user defined function within derived column component Would you be kind enough to give an example Thanks! Any reply or comment is highly appriciated. Robert You can simulate a simple coalesce by using the conditional operator.

• Visual C++ detecting ctrl+s

  Am doing windows sdk programming. am creating a notepad. Which msg(WM_KEYDOWN or WM_CHAR) is generated when i press (ctrl+s) and how do i detect it Sam Hobbs wrote: the answer is: Both! Both WM_KEYDOWN and WM_CHAR messages are generated for Ctrl-S. Just apparently (as a final effect), because Sam Hobbs wrote: there is good documentation about the keyboard and messages and such in the SDK documentation which states that MSDN wrote: The WM_CHAR message is posted to the window with the keyboard focus when a WM_KEYDOWN message is translated by the TranslateMessage function. ...Show All

• Visual C++ How to get a wave file from an embedded resource

  Hi All, I struggled mightily to figure this out and found no concise answers elsewhere so I thought I'd share. Plus I still have some questions at the end that I hope some kind .NET/CLR guru can answer. I wanted to embed a small .wav file into my C++ .NET Forms application so that I could deploy the single .exe file without the .wav file and play it with the SoundPlayer class. I did a lot of searching here but didn't quite find all the answers about how to do it in one place. But finally I have it working and here's how. 1. From Solution Explorer select your project, MyProject for example, then from the Project menu select "Add New Item" and choose "Resource" in the left pane and "Assembly Resource File&qu ...Show All

• Visual Studio Express Editions loading large pictures in picturebox

  Hello. I'm working with large pictures (one of them is 4021x3123) and I want to load them inside o PictureBox so the user interacts with it (draws on it). The problem is after I load the picture, when I use the scroolbar to move around it, it has that flicker effect and also the interaction with my application has a delay (it takes about 1 sec for the other controls to react). I'm guessing my problem appers because of the large picture I'm loading, so is there a way not to load the entire picture inside the PictureBox and only load that portion of the picture that is currently dispayed by the PictureBox Is there a better solution to that Thanks. Yes, I'm using double buffer and it doesn't help. ...Show All

• Windows Live Developer Forums Different pushpins for different services

  Does virtual earh have a list of pushpins like google and all you have to do is reference the number for each pushpin or do you have to use your own icons and reference the image... eg 1 : Hospital 2 : Food etc.... You'll have to customize your own pushpins using CSS styles.  Upon creating a VEPushpin you'll need to adjust when you pass into the parameters.  More information here: http://dev.live.com/virtualearth/sdk/ref/HTML/C_Namespace_VEPushpin_ctor.htm ...Show All

• Visual Studio Express Editions Installation Problem-setup refuses to run after installation

  I recently idownloaded VBE, when I click run a loading bar appears, loads and then disappears. I wait for awhile thinking something will load up but nothing does, it just disappears. On the windows task manager it is still running. On the manual download i used isohunters for extraction. But after extraction the instructions told me to open setup.exe, which did not exist in the extracted files. I have no previously installed components and my computer meets the expectations for the program. does anyone know how i can fix this I would use the downloaded ISo and make a cd, then install from there. The auto run system should take over for the install. Also you could look at the setup logs, these are loc ...Show All

• Smart Device Development How to Popup emoticons panel

  I want to add a popup emoticons panel which displays when user clicks on. Do u have any idea how to implement in .NET. Plz guide me in this matter. That means it's possible to create one (as it’s just a bunch of selectable bitmaps), it does not mean there's one for you to use. In fact I'm fairly confident there's no such thing as "emoticon panel" among standard controls. ...Show All
