A couple of issues I have found when using the win32 debugger within VS2005:

1. The behaviour of breakpoint toggling is a bit strange while actively debugging a running program (its fine when setting breakpoints wihtout a program running). Using the mouse or f9, the first click sets the breakpoint as expected, but you need to click twice more to delete the breakpoint - the red dot disappears from the source window on first click, however if you look at the breakpoints window its still there (although the "got to disassembly" button does become disabled !) and when running again, the breakpoint is still hit.

2. As in vs2003, when debugging a program that attempts to bring up a file selection dialog (either via get_selected_file or using win32api directly), the program simply hangs. I realise this is probably a nasty for the debugger.

...

On a positive note though, despite a few problems, the debugger is absolutely fab compared to the vs2003 one which would hang all the time - I can at last debug in visual studio so thanks all...

Hi Alan

I will take a look at the first point. Do you have an example that illustrates the second point?

The following win32 program runs okay normally, but if you attempt to debug using Visual Studio the program hangs within get_filtered_file@ without bringing up the file open dialog. (2003 or 2005). It works okay when using sdbg. It hangs somewhere within ntdll.dll.

! Demonstrates how Win32 debugger in Visual Studio (2003 or 2005) hangs when
! attempting to open file open dialog. This happens when the normal ClearWin
! get_filtered_file@ is used or when the dialog is opened by some other means
! (directly or via a C/C++ DLL)
program TestDebugOpenFile
use mswin

character*260 filename, filepath
character*32 filtname(2), filtspec(2)

filename = ''
filepath = ''
filtname(1) = 'Text Files'
filtname(2) = 'All Files'
filtspec(1)='*.txt'
filtspec(2)='*.*'

call get_filtered_file@('Select Text File', filename, filepath, filtname, filtspec, 2, 1)
end program
