Now I am using the MoveFileEx Function to delete the File at reboot. as Follows

GetModuleFileName(0,FileName,MAX_PATH);
	if ( ! MoveFileEx(FileName,NULL,MOVEFILE_DELAY_UNTIL_REBOOT ) )
		 dError = GetLastError() ; 
	PostQuitMessage(0);

But the Problem is that it is Not supported in Windows 95/98/Me. MSDN has provided the solution for that also. And trying to implement it

Use a .bat file. It will work on all version of Windows.

Notice that if you put:

del %0.bat

in a batch file and run it from a command prompt, it will remove itself. You can take advantage of this by creating a similar batch file from within the program you are wanting to delete:

:DoItAgain
del MyProg.exe
if exist MyProg.exe goto DoItAgain
rem del folder that MyProg.exe was in
del %0.bat

Use CreateProcess() to run the batch file. Note that I've not actually tested this so you may have to tweak it for your situation (e.g., add paths, hide console window).

Use an absolute path for this. What you have now is relative to whatever the CWD happens to be at the moment.

No, W will not be enough: the windows that are created w/o the W are non-unicode windows (there is a special API to check the Unicodeness of a window), and they cannot accept unicode strings in menus and other places; the system standard controls, like editbox or button, do support unicode, but the top level windows and dialogs must be created differently.

Cheers,

Alex

use _chdir(),_findfirst(),_findnext() etc
in proper combination to achieve your task.

Look up DlgDirListComboBox.

use the following code.Here m_letter is the member variable of combo box.

int k = 0;
DWORD MaxDriveSet, CurDriveSet;

TCHAR szBuf[300];
HANDLE hDevice;
PSTORAGE_DEVICE_DESCRIPTOR pDevDesc;

for(k=0; k<26; k++)
szMoveDiskName[k] = '\0';
k = 1;
// Get available drives we can monitor
MaxDriveSet = CurDriveSet = 0;

MaxDriveSet = GetLogicalDrives();
CurDriveSet = MaxDriveSet;
for ( drive = 0; drive < 32; ++drive )
{
if ( MaxDriveSet & (1 << drive) )
{
DWORD temp = 1<<drive;
_stprintf(="" szdrvname,="" _t("%c:"),="" 'a'+drive="" );

i do understand that CComboBox::Dir works. but it working only for the current working directory.. i wnat to list out the total number of directories available on the system.

ok.. will try that.. but u will have to tell me where to put that piece of code.

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