• Visual Basic System.Timers.Timer()

  SERVER: The .exe is running on a Windows XP server. DEVELOPMENT: Visual Studio 2005 Standard Edition LANGUAGE: VB.Net 2005 ERROR RECIEVED: The wait completed due to an abandoned mutex ERROR DESCRIPTION: I'm using a System.Timers.Timer() object inside a windows form. The application is started each day in the morning around 7:30. It runs smoothly all day, but errors out(the log shows it is at 7:31AM, which would be the call to the IfxRealTimeAppointmentLoad routine). Basically the application calls the IfxLoadTodaysAppointment() once and then continually calls the IfxRealTimeAppointmentLoad() routine every 5 seconds. What I'm trying to do is have the application stop calling both routines at 12:00AM and then start the entire ...Show All

• Visual Basic Need suggestion on control to use

  I would like to have a control that has columns & rows. Each row will have a button associated with it. It won't be tied to any data source. I've looked at the DataGridView control, and it seems like the steroid version of what I want. I don't like the gray column it has on the left side of it that tells me which row is selected. Also, I know I can make a column a button column, but I don't like that it shows as a column in itself. Is there a more basic kind of grid Thanks! Checkboxes are standard. Yes for images. Take a look at this: www.freewebs.com/reneecc That's a listview on the right. ...Show All

• Visual C# Debug vs. Unit Testing

  I was hoping to get some opinions about using the System.Diagnostics.Debug class instead of or in addition to NUnit unit testing. What do other developers favor more, Unit Testing or Debug Also what are your thoughts on using the Trace class with TraceListeners to implement logging of an application, say versus using a framework like log4Net Thanks. There is no way you can substitute unit testing for simple use of the Debug class (I'm assuming you mean use of Debug.Assert here ). This is useful for checking that you are in the right state within a class, but does not act as a test driver. You need to unit test to try and create the conditions that could cause your assertions to fail. I tend to use Debug.As ...Show All

• Visual C++ DLL Compatibility?

  I am converting an app from vc6 to vc8 (vs2005). I've got everything to compile fine, and most of the testing looks good. While system testing in Release mode, I get an occasional crash. The dialog box says "PCSMain.exe has generated errors and will be closed by Windows. You will need to restart the program. An error log is being created". Even though I have drwtsn turned on, I don't see any error logs being created. Even while running the app thru VS debugger, I don't get any helpful info when it crashes. I am taking a wild guess that the problem may be a library issue. Since I am using vc8, msvcr80.dll is used. But in looking at depends.exe for my exe, it looks like my db2 stuff also depends on msvcr71.dll. So my q ...Show All

• Windows Forms Binding text box fields to combo box selected value

  I have a small C# windows application with few text boxes and a combo box. I need to bind text fields to the value selected in the combo box, it works fine for the first selection but when I try to select another another item during the same session it gives me an error: "This causes two bindings in the collection to bind to the same property. Parameter name binding" .

  Good afternoon I have a speech recognition engine built with SAPI 5.1 on Windows XP. General problem: it doesn't work on Windows Vista. Details: when I try to use it in MS Word on Windows Vista the message "The referenced assembly is not installed on your system" is displayed.
