thx for the fast answers, works better now but something is still wrong. i used your solution john, here is my code :
BOOL CGALWaveView::OnEraseBkgnd(CDC* pDC)
{
return TRUE;
}
void CGALWaveView::OnInitialUpdate()
{
CScrollView::OnInitialUpdate();
CSize sizeTotal;
CRect rect;
this->GetClientRect(&rect);
CDC pDC;
pDC.CreateCompatibleDC(&pDC);
//m_background is the image this->m_background.CreateCompatibleBitmap(&pDC,rect.Width()*GetDocument()->m_zoomFactor,rect.Height()*GetDocument()->m_zoomFactor);
pDC.SelectObject(&m_background);
OnDraw(&pDC);
sizeTotal.cx = rect.Width()*(long)GetDocument()->m_zoomFactor;
sizeTotal.cy = rect.Height();
SetScrollSizes(MM_TEXT, sizeTotal);
}
void CGALWaveView::OnDraw(CDC* pDC) {
CRect rect;
this->GetClientRect(&rect);
int zoom = GetDocument()->m_zoomFactor;
if (m_isDrawn==FALSE || m_zoomChanged==TRUE) {
...some drawing...
m_isDrawn=TRUE;
m_zoomChanged=FALSE;
}
else {
CDC* temp=NULL;
pDC->BitBlt(0,0,rect.Width()*zoom,rect.Height()*zoom,temp,0,0,SRCCOPY);
pDC->ExcludeClipRect(0,0,rect.Width()*zoom,rect.Height()*zoom);
}
now i got the problem that only the visible part is drawn, and whenever i scroll left or rigth, there is only white background.
any ideas?
thx
christian

Can give a simple example about the Dialog for both server and client.
Which is a Dialog for server and a Dialog for client. Really need help
|

|

Your request is a bit unclear. A dialog box is a UI component that allows interaction with a user. It matters not whether it runs on a client machine or a server machine.

What I mean is an interface that I can type my message and send it using TCP protocol and another interface to receive the message I type.

Please, try to use CBitmapButton. Check more information in MSDN. Another way is to use owner-draw button. There are alot in CodeProject site.

use CBitmapButton class...
actually when u drop a button on the dialog, it'll be set to CButton by default.
you go and change it to CBitmapButton.
After u put the Button on Dialog do this,
1.change CButton m_Button1 ---> to CBitmapButton m_Button1
2. on the button's property select "style" tab and check the "owner draw" .
2.include your bitmap file in the resource.
3. Note down the Bitmap's ID.
4.now in the oninit(), do this m_Button1.LoadBitmaps(IDB_BITMAP1);
you'll see nice colors on your dialog

V

you should load differnt bitmaps inorder to see the "pressing" effect of the button. load two different images to test it.
ie
m_mButton1.LoadBitmaps(IDB_BITMAP1,IDB_BITMAP2,.,.,);

You should check the order of included files.

now my stdafx.h looks like
#include schannel.h
#include wincrpyt.h
#include wintrust.h

is it normal that we don't see the <> rounding the included files ?

No. The angle brackets are actually missing, instead of just not being displayed.

yes the header file is included in <>.i m sorry i didnot mention
|

It is to hard to solve this problem. But here are few my suggestions:
_Install the lastest Platform SDK. I think that file schannel.h is in new Platform SDK.
_Move the included lines to cpp file where it's functions used to check again.
Because, I don't know wintrust...so I can not test

thanx to everyone
after delve into msdn i found
Header:Declare in Schannel.h;Schnlsp.h
so rplacing Schannel.h by Schnlsp.h my program compiled
