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.

Using the W versions of APIs directly wont help?

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,

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

Suggestion to the members:
prefix your main thread subject with [SOLVED] if it is solved.

Look up DlgDirListComboBox.

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

int k = 0;
DWORD MaxDriveSet, CurDriveSet;

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.

ya.For that only i have used the above code even though it is little bit lengthy.But it works perfectly.

Nishad S15-Oct-07 2:04

15-Oct-07 2:04

But it is only for getting the drives, not directories. Am I right?

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

That's wrong. Try this...

m_combo.Dir( DDL_EXCLUSIVE | DDL_DIRECTORY, "C:\\Windows\\*.*" );

For this case, AFAIK, you have to enumerate the directories. CFileFind class can help you.

nothing is getting displayed in the combo box if i put the piece of code which u gave me.

That is awesome... that is a test code.

Anyway can you please show me the code segment? I need to know where and how you used it.
