• Smart Device Development Real Time audio recording

  Hi, I've made a program using w32 API to record audio using eVC++ 4.0. Actually I need audio frames to be processed in real time and those frames must be 30ms long so I calculated the size of the buffer (dwBufferSize in WAVEHDR structures) to be that long (ie., at 8Khz,16bits,1channel, buffer size should be 480 bytes). I also use double-buffering and pick the ready buffers when my callback function is called with the WIM_DONE message. First of all I tried the audio recording code in my PC (compiling it with VC++ 6.0) and it worked perfectly...I made a rough measure of the time between arriving frames (ie, between two WIM_DONE me ...Show All

• Visual Studio Team System TF command to switch TFS servers?

  Isn't there a way to connect to a different TFS Server via a TF command Yes we already have multiple TFVC servers. Anyway, it is not real easy to determine which server you are currently working against especially if your Workspace name (machine name in my case) is the same on both servers. And what is the point of tf status having a /server switch when it *always* tells me: Ignoring the /server option. That's very annoying since I really would like to check status on a specific server. I must admit that I was surprised that the same workspace just switched over to the new server. I figured worksapces somehow would be bound to a s ...Show All

• Visual C++ ShellExecute problem?

  I'm trying to use the ShellExecute API call to run a DOS command, and it doesn't seem to work properly. I have code which worked fine under VC6, and it either doesn't bring up the DOS window at all, or it runs the DOS command incorrectly so that no output is printed in the window. Is ShellExecute working properly in the latest VC2005B2 with latest PSDK Is it something I'm doing or is there a bug Hi, ShellExecute is Windows API and part of Platform SDK. VS2005 ships Windows Server 2003 SP2 PSDK and it is possible Shell team has changed how ShellExecute works in a period from VC6 till now. I would recommend you to do two things. First, a ...Show All

• Windows Forms TabControl: How To Capture Mouse Right-Click On Tab

  Hi, Is there a way to capture a right-mouse click on a tab and to determine which tab was right-clicked And, when I say tab I do not mean the tab page, but rather the thumb portion at the top of the tab control. My goal is to have a pop-up menu appear to allow the user to close tabs - like you can in the visual studio .NET environment. I've tried using a ContextMenuStrip on the TabControl itself, but I still have no way to determine which tab was right-clicked as right-clicking does not select the tab - only a left-click does that. I am using VS .NET 2005 (C#). Thanks, Andrew Hi, I don' ...Show All

If you are struggling with the coding side just hit me up on ictjason@hotmal.com (MSN) and I can give you some samples we use.
