Visual Studio Visual Studio Hangs - Need to restart IIS
We have installed Visual Studio 2005 Professional on a development server. Occasionally VS hangs. The only quick fix we have found is to restart IIS. Obviously we do not want to have to do this each time it hangs. Any idea what is causing the problem VS hangs when I open an .aspx file. By default it opens in source mode. It always seems to hang when first opening the first file in VS. If it opens and does not hang, VS will run fine. TRU ...Show All
Software Development for Windows Vista Setting volume levels with IAudioVolumeLevel
Hello, I've been trying to set the level of a particular part by using the IAudioVolumeLevel interface of the API. I can Activate a valid instance of the interface, and when I call GetLevelRange on it, I get a min value of -34.5, a max value of 12, and a step value of 1.5. However if I loop through the valid step values and set them with SetLevelUniform, while comparing the value of the volume level slider in the Control Panel (which goes from 1-100), I get unexpected results. The number on the slider (and volume from the speaker) remains at 0 for the first 8 iterations of the loop until I get to a level of -24 for the SetLevelUniform call, at which point the slider value moves to 1, where it remains until the 8th iteration in the loop ...Show All

.NET Development Serialport freezes
Hello, i'm developing app which reads incoming data from GPS receiver via serial port. The problem is that app freezes sometimes, even in Visual Studio IDE, when i attempt to close the app. Thank you for any kind hint. Yeah, at least until MSFT fixes this problem, that's a workaround that seems to be most practical. Windows makes sure that the handle to the serial port gets closed when your program terminates. ...Show All

Visual C++ CString corruption
This has happened before. I have data stored in a CString. I use atof to convert it. And I get this crazy number. And so I output using a message box and the number seems just fine as a string. So I then go to output it to a file as a string and a number and the string returns (null) and the number is all crazy. But write after I write the data to the file and I call messagebox the string is just fine. I'll post my code snippit. I have no idea whats happening. int count = -1; // Parse Data fin = fopen( "output.txt" , "w" ); for ( int i = 0; i < lines.GetCount(); i++) { if (lines [0] == '/' ) { // Start a new Data Series m_SeriesData.push_back(myData); myData.Clear(); ...Show All

Visual Studio Team System There are no tables in DB after database tier installation of TFS
I previously had a working installation of the TFS system, but was forced to rebuild the data tier, which wouldn't install with the old tables in the DB. To solve this I uninstalled everything from the data tier and began over from the begining. Everything goes well up until I install the database tier for TFS itself. The DT installs silently, as in no errors, but once it has run the DB looks the same as before, there are no new tables. I have tried adding the TFSSETUP account to DB admins and the same result occurs. This ultimately means the app tier can't find the DT installation on the specified machine. Why is the TFS install not creating the tables and is there another way to have them created or force the installer to try again ...Show All
.NET Development Out of memory exception (c#, .net 2003, large images)
Hi, I am developing an application (c#, .Net 2003, Framework 1.1) that deals with large images. The application captures multiple image frames and stitch them up into a large hige-res image. We are looking at 50+ frames and sometimes more than 100 frames of 1024x768 color images. I am also using double buffers for edit purposes. To get an idea of what this application does: beyond the image acquisition and stitching, it is very similar to Paint.Net ( http://www.getpaint.net/index2.html ) in providing tools to draw on top of the image. The program is hitting out of memory exceptions -- sometimes even with smaller images. Documentation on LOH seems to explain this observation well, especially with memory fragmentation a likely cause of ...Show All
Visual Basic DataSet Thread-Safety?
I have a multi-threaded application with several datasets that are read/written to from a couple threads. I have read that datasets can handle multiple readers and one writer. I have synclocks around all dataset writes and no synchronization around reads. I am experiencing random "Index was outside the bounds of the array." exceptions where a dataset item is in a conditional statement, for example: If CInt (CMPDAT.Tables(0).Rows(i).Item("ID")) = 0 Then Do I need to synchronize read operations as well Any help would be greatly appreciated. Thanks for the reply. I am still a little confused, for example I have a dataset that is only written to by one thread and read by an ...Show All
Visual C# How to delete a control during runtime?
Hi, I would like to know how to delete a control when the user presses the Delete key on the keyboard (For example, there is a label in the form, and the user clicks on it and presses Delete).
