Your pointer is not initialized so it points to invalid memory address. Instead of using a pointer, use the structure:

BROWSEINFO dir;
dir.hwndOwner = NULL;
...
...
...

SHBrowseForFolder(&dir);

Yes: use your debugger. It will help you to track the problem.

i cant even use the debugger... obviously that the first thing any developer will do.... the reason is that it is failing in gs_report.c

#if defined (_CRTBLD) && !defined (_SYSCRT)<br />
    DebuggerWasPresent = IsDebuggerPresent();<br />
    _CRT_DEBUGGER_HOOK(_CRT_DEBUGGER_GSFAILURE);<br />
#endif  /* defined (_CRTBLD) && !defined (_SYSCRT) */

and there is no traceable path backwards.

The display name of the object selected is returned in the buffer pointed to by the pszDisplayName member of the BROWSEINFO parameter structure.

pszDisplayName
Address of a buffer to receive the display name of the folder selected by the user. The size of this buffer is assumed to be MAX_PATH characters.

D'Oh! | :doh:

BROWSEINFOW dir;
WCHAR wcDisplayName[MAX_PATH];

...
dir.pszDisplayName = DisplayName;
...

function with variable param

Hey, i have a trouble for all. That is: For example: I want to write a function that display a messagebox with many param that i want. It should like this (like sprintf())
ms(HWND hwd,char *control_string,...){
static char *c[1000];
sprintf(c,control_string,???);
MessageBox(hwd,c,"ms",0);
};

Understand, but i don't know what ??? is ?.

If i have this function then i can call this function very useful like this:
ms(0,"%s%i%s",
"Untill now, I posted: ",
10000000000000,
" question!");

Is it useful?

You have to use va_arg, va_end and va_start macros. Try this:

#include <stdarg.h>
// ...
void ms( HWND hwd, const char * control_string, ...)
{
    va_list argptr;
    va_start(argptr, control_string);
    char c[1000];
    _vsnprintf(c, 1000, control_string, argptr);
    MessageBox(hwd, c, "ms", 0);
    va_end(argptr);
};

Hope it helps.

Try use this lines Wink | ;)

:

int EnhMessageBox(HWND hWnd, int mbFlags, LPCSTR pCaption, LPCSTR pTextFormat, ...)
{
va_list args;
va_start(args, pTextFormat);
int bufSize;
char pBuffer[MAX_PATH*4] = "\0";
bufSize = vsprintf(pBuffer, pTextFormat, args);
va_end(args);
return MessageBox(hWnd, pBuffer, pCaption, mbFlags);
}

Maybe WM_DISPLAYCHANGE notification is what you need.

I think you have to write a program using the MSI API and open the MSI files yourself and do all the 'property extraction'.

I use orca.exe to get to the heart and soul of the MSI file.

Look for the orca.msi hidden in the ~~windows 2000 resource kit~~ directories. Install it and then you can right click on an MSI to view it's database for reading/writing etc...

I had used
if(m_bMinimize)
CMyDlg::ShowWindow(SW_MINIMIZE);
;
;
;
;
;
CMyDlg::ShowWindow(SW_SHOWMAXIMIZED);

This code is written in a button click of my Dialog.
The Dialog is minimised but it does not maximise again.
This is working fine in VC++ but does not working in WinCE

Hey I'm sorry!! CE doesn't support SW_SHOWMAXIMIZED But I think you can stil do it with ::MoveWindow instead. Move it to the size of the screen coordinates Cool | :cool:

And always have this in your hand...

yes you can use MoveWindow or SetWindowPos instead this function

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
