• Visual Studio Express Editions Visual Studio C++ Express Edition Hangs on Breakpoint!

  Using: Visual C++ Express Editon (release version) on a new install of Windows XP Pro (so I don't have all the old beta .NET cruft from previous betas anywhere and never have on this install). I have one (unmanaged native C++) project in which any time I hit a breakpoint, rather than the IDE breaking as expected, it seems to go into a weird loop with the Solution Explorer window blinking (as if being constantly redrawn).  The IDE is completely useless at this point until I go into the task manager and kill the VC IDE process.   The same behavior occurs if, instead of placing a breakpoint with the IDE, I insert an _asm { int ...Show All

• Windows Forms Defect in MainForm.MainForm_Load()

  Just a note, I discovered a bug.  If you have no projects, GetLookUpTables() is never called.  As a result, if you goto ManageUsersForm, there's nothing in the list for users.  :) I agree...it's the last line of the IF block for Project.Rows.Count > 0. ...Show All

• Visual C# blocked zip files using zipsharp library

  I had a program created in C#.net that zips a folder up for me automatically. We used the zipsharp library and it seems to work great execpt when you try to open it using windows to extract the files from the zip. If you try to extract the files you get a message saying "windows has blocked access to these files to protect your computer" and it tells you you can fix this by right clicking the zip file and go to properties and check the "unblock" box and all will be fixed. However there is no "unblock" option anywhere. I can use winzip or winrar to open and extract the file just fine but windows will not work. It seems to be somet ...Show All

• Visual C++ Strange compiler error (C2664)

  void f1(const int a[2][5][3]) { } void f2() {  int b[2][5][3];  f1(b); } Causes the following error in VS6: C:\Roman\Projects\simulator\tmp\src1.cpp(6) : error C2664: 'f1' : cannot convert parameter 1 from 'int [2][5][3]' to 'const int [][5][3]'         Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast I note also that with only 2 or 1 dimension, the error does not appear. const_cast does not help as well (although I can't understand why should I have one). Any ideas Thanks, Roman. Try to leave the first dimension open. void f1(const ...Show All

• Windows Forms Make Form Designer Generate Code in .cpp instead of .h?

  I know that if I move the  InitializeComponent method to the .cpp, Form Designer will generate all control init codes in the .cpp file, but it continues to generate all event codes in the .h file.  Is there anyway have all generated code not be in the .h file It is considered good object-oriented programming practice to put only declarations in the .h files.  Implementation code should go in the .cpp files.  One reason for this is that presumably you could share your .h files with the public, but not share the implementation of the code contained in the .cpp files (which could be compile ...Show All

• Visual Studio Team System Override check in

  How does an admin on team foundation server override a check in   We have a developer who has left for a few days and he has files checked out   We need to force a check in on those files   If you want to undo someone else's check out through the SCE, you can't currently do that - you need to use "tf undo" from the command-line to do so. See this other thread that discusses how to do so: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=132995&SiteID=1 ...Show All

  Can someone look at my code below and tell me what I'm doing wrong I converted VBScript to C# for ASP to ASP.NET migration.

• Visual Studio Express Editions Need a faster ArrayList save to text file

  Hi I have used a variety of file write routines to try to find a quick way of saving an ArrayList of 240,000 strings. The best I have managed so far takes an awful long time, 20 minutes and hadn't finished when I stopped it. In all my attempts, I have to split off each word from the ArrayList and File.Append it to the file. I can see that is not an efficient way of doing it, but I can't find an alternative method. What is the best/fastest approach to write a large ArrayList to a text file I use a routine based around the following which reads the same file almost as fast as I can blink, but what would be the equivalent Write o ...Show All

• Visual Studio Express Editions Copying a SQL Server Express database along with my Website

  Hi! I used Visual Studio Express Web Developer to create a small website containing a SQL Server 2005 Express database.  On my laptop, where I have everything installed, the website works just fine. When I tried using the Copy Website function in WD Express (to copy from my laptop to IIS running on my desktop PC), the website was copied successfully but the database didn't copy.  So, on my desktop, the website fails when trying to access the (non-copied) database. I expected that when using the Copy Website function, it would copy the database, too.  I can understand why that might not h ...Show All

• Visual Studio Error in Sub Main()

  My application is in VB.NET (upgraded from vb6.0 to VS 2003) and interacts with the data access layer to access database. I have put breakpoints in the application for debugging. One of the breakpoints is on 'Public Sub Main()' of the application which is the entry point for the application. When the application reaches this breakpoint, it displays an error message found in a method 'GetValue' in data access layer though this method is not yet called nor the class in which this method is found is instantiated. After adding a few display messages in the data access layer, I can see that the control is not coming dire ...Show All

  Can anyone point me to an example which will call an external .bat file (within the working directory) when a VB button is pressed I'm able to develop the GUI with a single button however I'm struggleing with declaring the .bat file within VB. Could also use an example which shows how a .dll file is declared.     You could try this: 1.) Call the CreateProcess API routine to sysdevice:\windows\system32\cmd.exe 2.) Give it the path and file spec as an argument 3.) CreateProcess has a lot of arguments and flags. One of them is NoWindows 4.) If you desire, you can synchronize on t ...Show All
