Well, that's the same thing I said as well in my reply to the OP. And, that would be the only possibility. 
If a device is sensitive to such data, and is exposing APIs to capture that information, then that would be a different story. However, it is not the case with regular mouse and touch pad devices.

AFAIK and i too agree with rajesh, there is no such api's in windows.. but might be your touch screen vendor may be providing these type of library if your client are intrested in same type of functionality

Hi. I have been reading articles, messages and anything I can find but I still
cannot get a DIBSection to work. Can anyone tell me what I am doing wrong or point
me to an article that explains how to use one.
This code as written works,it paints the window red. But when I use the two commented lines instead of CreateCompatibleBitmap I get nothing. The handle returned by CreateDIBSection seems wrong, when I hover the mouse over it debug says it is unused.
Any help at all would be great. Thanks in advance.
void CChildView::OnDibtstTest(){
CRect r;
GetClientRect(&r);
BITMAPINFO *pbmInfo = new BITMAPINFO;
memset(pbmInfo,0,sizeof(BITMAPINFO));
pbmInfo->bmiHeader.biSize=sizeof(BITMAPINFOHEADER);
pbmInfo->bmiHeader.biWidth=r.right;
pbmInfo->bmiHeader.biHeight=r.bottom;
pbmInfo->bmiHeader.biPlanes=1;
pbmInfo->bmiHeader.biBitCount=32;
pbmInfo->bmiHeader.biSizeImage=r.right*r.bottom*4;
void *pImg;
CDC *pDc=GetDC();
CDC *pmDc = new CDC;
pmDc->CreateCompatibleDC(pDc);
CBitmap *pcBm = new CBitmap;
// HBITMAP hBm = CreateDIBSection(pDc->m_hDC,pbmInfo,DIB_RGB_COLORS,&pImg,NULL,0);
// pcBm->FromHandle(hBm);
pcBm->CreateCompatibleBitmap(pDc,r.right,r.bottom);
pmDc->SelectObject(pcBm);
CBrush br(RGB(255,0,0));
pmDc->SelectObject(&br);
pmDc->Rectangle(0,0,r.right,r.bottom);
pDc->BitBlt(0,0,r.right,r.bottom,pmDc,0,0,SRCCOPY);
delete pbmInfo;
delete pmDc;
delete pcBm;
}

i believe this does not do what you think it does. Try with
pcBm->Attach(hBm);

Thank you very much code-o-mat! That did the trick.
Can you tell me why FromeHandle does not work?
|

FromHandle returns the CBitmap object that has already been attached to the bitmap handle, if no such CBitmap object exists, it creates a temporary one and returns a pointer to that one. It will not attach your object to the handle. FromHandle is actually a static method.
CBitmap *bmp = new CBitmap;
bmp->FromHandle(hbmp);
is the same as
CBitmap::FromHandle(hbmp);

Now here is a class
class CPipeLineApp: public CWinApp
{
public:
CDengLu* dgDlg;
.......
}
I want to set dgDlg as a extern variable so that I can call dgDlg in class CMainFrame.
dgDlg has variables :name and pass.
I want to call them too.
Please lend me a hand.

As it is, dgDlg can be accessed from any CMainFrame method.

As far as I understand your question, you can access it like below.
((CPipeLineApp*)AfxGetApp())->dgDlg;

But, I couldn't find out how I could save it as default in my settings. Do you know how?

You don't have to set that as an extern, its public and part of CMainFrame... means you should be able to reach it from any CMainFrame... what are you trying to do?
|
|
|
|
|
I'am so sorry .I've made a serious mistake.
class CPipeLineApp : public CWinApp
{
public:
CDengLu* dgDlg;
.....
};
I want to call dgDlg in class CMainFrame.
I also want to call dgDlg's variables: name and pass
Forwarding your help.

|
|
still not sure what the problem is... if CPipeLineApp is derived from CWinApp, then he owns the CMainFrame, so you have complete access to it...
|
|
|
|
|
...I'm thinking you don't really know the MFC framework?
