Maybe you can use TransparentBlt() in NT. This is an easiest way to paint with a transparent color.

Hi there,
I have an addin to ms Word written in visual c++ implementing the IDTExtensibility2 interface.
I sink events properly and launch my functions...
My question is..how can I call those functions from a different c++ project?(that should be possible)
need I to register them as word native functions, can I use messages to call them?...

thanks and happy codding
AB.

Bitmap dialog

Hello Friends,
I'm developing an application in which there are few dialog boxes and i decided to make them colourful using bitmaps,So i used the OnEraseBkGnd function to load the bitmaps .but there was an mismatch between the dialog size and bitmap size so i decided to capture the size of the dialog and the bitmap,after which i repainted the dialog calling the BitBlt function many number of times.
Is there anyother way to load the bitmaps so that i dont have to call the BitBlt function more than once.I've attached the piece of code what i'm using now.it'd be great if someone could help me in this...
BOOL dialog::OnEraseBkgnd(CDC* pDC)
{

CBitmap bmp;
CBitmap *ptrBmpOld;
CDC dcMemory;
BITMAP bm;
CRect rect;
int i, j;
int nHor, nVer;
bmp.LoadBitmap(IDB_BITMAP1);
bmp.GetBitmap(&bm);
GetClientRect(rect);
nHor=rect.Width()/bm.bmWidth+1;
nVer=rect.Height()/bm.bmHeight+1;
dcMemory.CreateCompatibleDC(pDC);
ptrBmpOld=dcMemory.SelectObject(&bmp);
for(i=0; i<nhor; i++)
{
for(j="0;" j<nver;="" j++)
{
pdc-="">BitBlt
(
i*bm.bmWidth,
j*bm.bmHeight,
bm.bmWidth,
bm.bmHeight,
&dcMemory,
0,
0,
SRCCOPY
);
}
}
dcMemory.SelectObject(ptrBmpOld);
return TRUE;
}

You could use CStatic objects, to which you set the bitmaps using SetBitmap(HBITMAP hBitmap)

Hey Rajeev
How ru ?

Just dont use any type of coding .

This will be more siple .

Yeh ur true Rajeev
As the the OnEraseBkgnd will be oftenly called
if ur going to do BitBlt in that function the
5speed will be slow .
Have u tried to use the same code with OnDraw
member function.
U can aslo try to add the code on WM_INITDIALOG.

take care
send me the feedback when u have dont it. Blush | :O

If this is an MFC application, have you considered CenterWindow()?
