Hi,
   Thanks for your reply.

	CBitmap m_Bit;
	m_Bit.LoadBitmap(IDB_BITMAP1);

	HBITMAP hSourceBitmap = (HBITMAP) m_Bit;

   Is this a correct way?

why you use HBITMAP hSourceBitmap you can use m_Bit.m_hObject and i think you dont need to hbitmap handle

AFAIK, that is not possible, unless you write some kernel extension. This is what rootkits normally do, and is not considered "kosher". It's also a bad idea to hide processes like that, in case you need to kill a process manually.

Why the tough restriction on process visibility, if I may ask?

you can get the app with AfxGetApp:

CMyApp *pApp = (CMyApp*)AfxGetApp();

Hi
A common way to handle one instance is using an identifier

<br />
BOOL CMyApp::InitInstance()<br />
{<br />
	HANDLE hMutex =  CreateMutex   (NULL, TRUE, "MY APP IDENTIFICATION");<br />
	if (GetLastError() == ERROR_ALREADY_EXISTS)<br />
	{<br />
		AfxMessageBox("Alreay running!");<br />
		return FALSE;<br />
	}<br />
	if(hMutex)		ReleaseMutex (hMutex);<br />
	...<br />
}<br />

Is UNICODE required for my project

benm9999999910-May-06 9:23

Hi,

We have a C++ service that needs to scan the filesystem and report back an inventory. Some filenames are in Hebrew.

Our project is currently Multibyte, we use CString and CFileFind, and the Hebrew characters are shown as '???'.

Can someone explain if we MUST switch to UNICODE or is there some way to make it work in MBCS ? I was under the impression MBCS also supported other languages. I see I can use CStringW to hold Hebrew chars, but CFileFind still returns '?' characters... Is there a way to define UNICODE locally only for a certain class ? I tried, but CString still isn't UNICODE since afxwin.h is included in the precompiled header.

The problem is switching to UNICODE causes a ton of errors all over the place, and in some classes we downloaded from the web, which used CHAR in some places instead of TCHAR.

I'll appreciate any advice,
Ben

SBCS and MBCS only work if you know which code page you are working in. You should do this application in UNICODE.

Not quite sure but
1) DLL has to be a debug-build one.
2) Debugger has to locate the .pdb file which came from building the DLL.
3) Source code (not sure)...
