or use like this:

#include "StringA.h"
#include "StringW.h"

CStringW sTestW( L"Test" );
CStringA sTestA( "Test" );

// convert
CStringW sConvertW = sTestA;
CStringA sConvertA = sTestW;

Try it

CImage::Attach(HBITMAP);
CImage::Save(LPCTSTR);
CImage::Detach();

Hi all,

I was trying to make self deleting executable. I found a article on code project []

my problem is i am stucked at one place my folder is not getting deleted.

// temporary .bat file  
	CString templ =
	"del \"%s\"\r\n"
	"taskkill /im selfdelete.exe\r\n"
	"del \"%s\"\r\n"
    "rmdir /S /Q \"%s\"\r\n"	
    "del \"%s\"" ;

	//CString temppath;

	CString tempstr;
	CString modulename;

	LPTSTR pPath = tempstr.GetBufferSetLength(MAX_PATH);
	GetTempPath ( MAX_PATH, pPath );
	tempstr.ReleaseBuffer();
	tempstr = tempstr + tempbatname;

	LPTSTR modulenm = modulename.GetBufferSetLength(MAX_PATH);
	GetModuleFileName(NULL,modulenm,MAX_PATH) ;
	modulename.ReleaseBuffer();

	CString str = modulename;
	int k = str.Find('\\');
	while(k >= 0)
	{
		str = str.Right(str.GetLength()-k-1);
		k = str.Find('\\');
	}

	CString folder = modulename.Left(modulename.GetLength()-str.GetLength());

	CString iniFile = folder;
	CString file = "\\selfdeletepath.txt";
	iniFile = iniFile + file;

	HANDLE hf ;
	hf = CreateFile(tempstr, GENERIC_WRITE, 0, NULL,CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL) ;
	
	if (hf != INVALID_HANDLE_VALUE)
	{
		DWORD len ;
		CString bat ;
		LPTSTR bBat = bat.GetBufferSetLength(MAX_PATH);
		bat = (char*)alloca(strlen(templ) + strlen(modulename) * 2 + strlen(tempstr) + 20) ;
		wsprintf(bBat, templ,iniFile, modulename, folder, tempstr) ;
		WriteFile(hf, bat, strlen(bat), &len, NULL) ;   
		CloseHandle(hf) ;
		ShellExecute(NULL, "open", tempstr, NULL, NULL, SW_HIDE);  
	}

}

can anybody please tell me what i am doing wrong.

thanks in advance

I smell this exe itself to be like a virus
Well i think you are doing something which is weird Poke tongue | ;-P

ShellExecute itself, check the argument.
Well i am doubted about your logic of deletion.

I believe you can achieve the deletion in XP with a different logic.
Create a remote thread and attach to some other process before exiting your native executable, and then delete from that remote thread.
Just try that Smile | :)

How to set DLL version?

Dear all,

I have made a DLL using VS - 6. But it does not display any information when i go through by right click on it and goes to property. In case of other Microsoft DLL, that shows many info. So how can I set like author, version info etc.

Thanks to all

You have to modify you version section of the app resources:
Solution View -> app.rc -> ContextMenu ->
Open With -> Resource Editor -> ContextMenu ->
Add resource -> Version Smile | :)

OnSize() problem in Maximize

Hi,
In my VC++ MFC applcaiton,i have different views.And in each view,when i maximize it,i changed the size and position to new thing(Normally it fully get maximixed to screen size).But i dont want tht.So in OnSize() i coded like this.

void CChildFrame::OnSize(UINT nType, int cx, int cy)
   {
       CMDIChildWnd::OnSize(nType, cx, cy);

       int XBorder = GetSystemMetrics(SM_CXMAXIMIZED);
       int YBorder = GetSystemMetrics(SM_CYMAXIMIZED);
       switch (nType)
       {
           case SIZE_MAXIMIZED:
              SetWindowPos(NULL,0,60,XBorder-45,YBorder-60,SWP_NOZORDER );
              break;
       }
   }

But what happened is?When i maximize the view,its get maximized to above mention size only.But in that blue bar,there si no minimize,maximize,close button.
When i double click in the blue bar,its get to resumed to previous postion with all buttons.
How can i get that?

Try AfxGetMainWnd()->SetWindowPos(..) Smile | :)

Better - you implement this (OnSize(..)) reaction
for your MainFrame only Smile | :)

Can you get the button by border-resizing after the action ? Smile | :)

Can you see the button at the child blue bar after

case SIZE_MAXIMIZED:
  SetWindowPos(NULL,0,60,XBorder-45,YBorder-60,SWP_NOZORDER );
  break;

when you just resize the child frame at its border ? Smile | :)

When opening that child window it has buttons in bar.
When i maximize,the buttons are added to mainfrmae(as usual,normally it will happen like this only).
Only the child window with empty bar(without system menu)is appearing.

Please test it:

  ON_WM_GETMINMAXINFO()
  //}}AFX_MSG_MAP
END_MESSAGE_MAP()

{
  lpMMI->ptMaxTrackSize.x = 400;
  lpMMI->ptMaxTrackSize.y = 200;
