if you want to use brush in ctlcolor use

<br />
CBrush *m_brush;<br />
CBitmap m_Bitmap;<br />
m_Bitmap.Attach(LoadImage(...));<br />
m_brush=new CBitmap(&m_Bitmap);<br />

now in ctlcolor return m_brush->GetSafeHandle();//i think this (GetSafeHandle) i dont have vc now
in the end delete m_brush

i want to display different bitmaps of digital no. in subclass static control.i have created an array of handle of HBITMAP and i am getting all the handle in constructor. when i am trying to access from a click of button in dialog its not displaying the digit.
code is below:
// this the derived class constructor
CNewstatic::CNewstatic()
{
for(int i=0;i<=11;i++)// code for getting the handle
{
HBITMAP temp = (HBITMAP)::CreateMappedBitmap(AfxGetApp()->m_hInstance, IDB_BITMAP1+i, 0, NULL, 0);
m_hBitmap[i] = (HBITMAP)::CopyImage( temp, IMAGE_BITMAP, 0, 0, LR_COPYRETURNORG | LR_COPYDELETEORG);
}

}

after a button click i am accessing the objects in a method//

void CNewstatic ::OutPut(int digit,int pos)
{
CRect rect;
GetClientRect(&rect);
m_w = rect.Width()/8;
m_h = rect.Height();
pos =0;
//CBitmap* pBitmap ;//CBitmap::FromHandle( m_hBitmap[digit]);
CClientDC dc(this);
CDC dcMem;
dcMem.CreateCompatibleDC(&dc);

//pBitmap->LoadBitmap(IDB_BITMAP1);
CBitmap* pBitmap = CBitmap::FromHandle( m_hBitmap[0]);
CBitmap* pOldBitmap = dcMem.SelectObject(pBitmap);

dcMem.SelectObject(pOldBitmap);

int f = dc.StretchBlt(m_w*pos, 0, m_w, m_h,
&dcMem, 0, 0, m_bm.bmWidth, m_bm.bmHeight, SRCCOPY);
if(f)
AfxMessageBox("Create");
else
AfxMessageBox("Not Create");
dcMem.DeleteDC();

}
it gives create message after clicking the button but image is not displayed .
please tell me the reason and solution of the problem.

My guess is that you're selecting out your bitmap too early...

I don't think you understood me. You are selecting your bitmap out before you do the stretchblt. You should select out your bitmap after the stretchblt. I'm actually not sure why you are using CClientDC though. Are you drawing in response to WM_PAINT? Because then you would have a CPaintDC and you should be doing the drawing with it.

Load String From Resource (String Table)

I use windows forms in my project. This project must have multilanguage support. How can I load string from resource (String table) without using MFC. But If mfc is adaptable into windows forms, may be it is used. I don't know this.

You can use LoadString(..) or LoadResource(..)
Both are Platform SDK functions and not MFC related

Thanks for your fast replying. How can I use this methods or functions? (LoadStrıng or LoadResource)

like that :

CString strMainTitle;
strMainTitle.LoadString(IDS_MAINTITLE);
this->SetWindowText(strMainTitle);

CString is in MFC library. But I must load string without using MFC library.

i'm providing the signature of those functions,

int LoadString(HINSTANCE hInstance, UINT uid, LPTSTR pBuffer, int nBufferLength);

HGLOBAL LoadResource(HMODULE hModule, HRSRC hResourceInfo);
HRSRC FindResource(HMODULE hModule, LPCTSTR lpName, LPCTSTR lpType);

Refer the following link for more info and to know how to use them,

int LoadString( HINSTANCE hInstance,
UINT uID,
LPTSTR lpBuffer,
int nBufferMax
);

Unfortunately, I couldn't understand first parameter of this function. Can you explain this parameter?

If the StringTable is in the same application then you can pass NULL as first parameter

"error C3861: 'LoadString': identifier not found, even with argument-dependent lookup"

Can you tell me that what is the reason of this error? All the parameter of this functon are correct as given below.

TCHAR sz[160];
LoadString(NULL,IDYES,sz,sizeof(sz));
