I tried that but it still doesn't work. I placed RBDeskBand.dll in the Windows\System folder and then typed (in DOS):

Regsvr32.exe RBDeskBand.dll

Then there is a popup that says: "DLLRegisterServer in RBDeskBand.dll succeeded." The problem is that if I then double click on RegSvr32.exe it says "No DLL Specified" and there is no extra menu in VC++. I am doing this to the RegSvr32 in my Windows\System folder, is this the correct one??

That means it worked. RegSvr32 is a utility program that "registers" and "unregisters" COM/ActiveX objects by calling standard functions provided in the object DLL.

If no extra menu appears in VC++, then you've probably missed some other part of the installation process. Consult the original article, or maybe e-mail the author.

OK, I guess it worked but the thing is that I've never been able to use the ATL Object Wizard. For some reason it is disabled on my computer. I have all the files that are used in it, anyone know why I can't use it?

How do I delete a directory and its contents? I've tried DeleteFile and SHFileOperation, but with no luck Frown | :(

To delete all files in a directory, you have to enumerate all files recursively and delete every file separately.

See these articles for how to do it:

Delete folders, subfolders and files easily

Empty Directory Utility Under NT
http://www.codeguru.com/files/delTree.shtml[^]
Also works on Win9x.

SHFileOperation is the right way to do it. Show your code, perhaps you are not doing it right.

bool SHCopyFile(CString ExistingFile,CString NewFile)<br />
{<br />
	bool RetVal = false;<br />
	SHFILEOPSTRUCT FileOp;<br />
	ZeroMemory ( &FileOp, sizeof ( FileOp ) );<br />
	FileOp.hwnd = theDlg->m_hWnd;<br />
	FileOp.wFunc = FO_COPY;<br />
<br />
	FileOp.pFrom = new char[300];<br />
	strcpy((char*)FileOp.pFrom,ExistingFile.GetBuffer());<br />
	ExistingFile.ReleaseBuffer();<br />
<br />
	FileOp.pTo = new char[300];<br />
	strcpy((char*)FileOp.pTo,NewFile.GetBuffer());<br />
	NewFile.ReleaseBuffer();<br />
<br />
	if(SHFileOperation(&FileOp) == 0)<br />
		RetVal = true;<br />
	else<br />
		RetVal = false;<br />
<br />
	delete FileOp.pFrom;<br />
	delete FileOp.pTo;<br />
	return RetVal;<br />
}

This is the copy code, but the delete code is just like it (except for wFunc and pTo). Actually, I can't get this function to work, either; am I doing something wrong with allocating pFrom and pTo?

I just tried this code out and it worked fine on my machine :-

SHFILEOPSTRUCT FileOp = {0};
FileOp.hwnd = m_hWnd;
FileOp.wFunc = FO_COPY;
FileOp.pFrom = "c:\\abc";
FileOp.pTo = "c:\\abccopy";
SHFileOperation(&FileOp);

If I do FileOp.pFrom = "d:\\testdir", it works, but if I do FileOp.pFrom = Dir.GetBuffer() it doesn't work, even though Dir=d:\testdir!

Also, I've been fiddling with the copy operation:

bool SHCopyFile(CString ExistingFile,CString NewFile)<br />
{<br />
	bool RetBool = false;<br />
	SHFILEOPSTRUCT FileOp;<br />
	ZeroMemory ( &FileOp, sizeof ( FileOp ) );<br />
	if(theDlg != NULL)<br />
		FileOp.hwnd = theDlg->m_hWnd;<br />
	//FileOp.fFlags = FOF_NOCONFIRMATION | FOF_NOERRORUI;<br />
	FileOp.wFunc = FO_COPY;<br />
<br />
	FileOp.pFrom = "d:\\test.zip";//ExistingFile.GetBuffer();<br />
	ExistingFile.ReleaseBuffer();<br />
<br />
	FileOp.pTo = NewFile.GetBuffer();<br />
	NewFile.ReleaseBuffer();<br />
<br />
	int RetVal = SHFileOperation(&FileOp);<br />
	if(RetVal == 0)<br />
		RetBool = true;<br />
	else<br />
		RetBool = false;<br />
<br />
	return RetBool;<br />
}

If FileOp.pFrom ="d:\\test.zip", it works, but if I use ExistingFile, it doesn't. It works fine with FileOp.pTo = NewFile.GetBuffer(), though, if pFrom = "d:\\test.zip"!

Read the SHFileOperation() docs carefully, pFrom and pTo have to be double null terminated strings. Fill the arrays you allocate for pFrom and pTo with zeros.

Ok, that works, but now I can't call delete on anything because of "HEAP[FLModManager.exe]: Heap block at 003F2CB8 modified at 003F2E10 past requested size of 150"

My code:

bool SHCopyFile(CString ExistingFile,CString NewFile)<br />
{<br />
	bool RetBool = false;<br />
	SHFILEOPSTRUCT FileOp;<br />
	ZeroMemory ( &FileOp, sizeof ( FileOp ) );<br />
	if(theDlg != NULL)<br />
		FileOp.hwnd = theDlg->m_hWnd;<br />
	//FileOp.fFlags = FOF_NOCONFIRMATION | FOF_NOERRORUI;<br />
	FileOp.wFunc = FO_COPY;<br />
<br />
	FileOp.pFrom = new char[300];<br />
	strset((char*)FileOp.pFrom,0);<br />
	strcpy((char*)FileOp.pFrom,ExistingFile.GetBuffer());<br />
	ExistingFile.ReleaseBuffer();<br />
<br />
	FileOp.pTo = new char[300];<br />
	strset((char*)FileOp.pTo,0);<br />
	strcpy((char*)FileOp.pTo,NewFile.GetBuffer());<br />
	NewFile.ReleaseBuffer();<br />
<br />
	int RetVal = SHFileOperation(&FileOp);<br />
	if(RetVal == 0)<br />
		RetBool = true;<br />
	else<br />
		RetBool = false;<br />
<br />
	//delete FileOp.pFrom;<br />
	//delete FileOp.pTo;<br />
	return RetBool;<br />
}

Hi, I get an error when i want to compile an empty C# form...

What is that???

I'm not sure but I did a search on Yahoo / Google and found someone with the same problem, they said that they deleted the license file then rebuilt and it fixed their problem.. maybe try renaming the file to .old or something like that and try to re-compile..

I want to create some checkboxes dynamicaly from code and I want them tranparent. The problem is that I tried to create them from resource with the trasparent atribute (WS_EX_TRASPARENT) but it still didn't work. Anyway my problem is to create them dynamically. Any ideas, sugestions ?

WS_EX_TRASPARENT style does not make it transparent, just tells window to paint control after children. I am sure you can find plenty custom draw samples on this and others websites.

Handle WM_CTLCOLORBTN and in your handler, call SetBkMode(TRANSPARENT) on the HDC that is passed in the message's wParam.
