you answerd always "can you tell me the code for this" yes
include atlImage.h

CImage m_Image;
m_Image.Load(filename);

<br />
m_Image.BitBlt(dc.m_hDC,CRect(0,0,800,600),CPoint(0,0));<br />
use this code in WM_PAINT <br />

Did you even bother to search for a solution? It is assumed that you will at least put forth some effort to go along with the suggestons you receive here.

You can do it by handling WM_CTLCOLOR

Follow the below steps,

CBitmap m_hBitmap; //Declare in class
m_hBitmap.LoadBitmap(filename); // Add this in Constructor
m_hBitmap.DeleteObject(); // Add this in Destructor

Use the following code in WM_CTLCOLOR handler, before the return statement

if (CTLCOLOR_DLG == nCtlColor) //nCtlColor is the 'in' parameter
{
hbr = ::CreatePatternBrush((HBITMAP)m_hBitmap.m_hObject);
}

thanks but it does not work
but i use this code and no wallpaper is appeared
CBitmap m_hBitmap; //Declare in class
m_hBitmap.LoadBitmap("D:\\pics\\image001.jpg);
if (CTLCOLOR_DLG == nCtlColor) //nCtlColor is the 'in' parameter
{
hbr = ::CreatePatternBrush((HBITMAP)m_hBitmap.m_hObject);
}

that will work if you have the bitmap in the resource.
if you are using the bitmap from file, then use the following code,

HBITMAP hBitmap; //Declare in Class

hBitmap = (HBITMAP)::LoadImage(NULL, "C:\\filename.bmp", IMAGE_BITMAP, 0,0,LR_LOADFROMFILE); //in Constructor

::DeleteObject(hBitmap); //in destructor

//Add in WM_CTLCOLOR handler
if (CTLCOLOR_DLG == nCtlColor)
hbr = ::CreatePatterhBrush(hBitmap);

thanks
but these are errors
'CreatePatterhBrush' : is not a member of '`global namespace''
'CreatePatterhBrush' : undeclared identifier
'=' : cannot convert from 'int' to 'struct HBRUSH__ *'
Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or function-style cast

in the
hbr = ::CreatePatterhBrush(hBitmap);

It helps to spell the function correctly. Roll eyes | :rolleyes:

Displaying problem in Bitmaps

11-Jul-06 19:44

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

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