Understood, but I think you can still use LineTo() to modify the bitmap, and then display the final result. You need to select the bitmap into a compatible DC, add to it using LineTo(), and then draw it using BitBlt(). Something like:
CDC dcCompatible;
dcCompatible.CreateCompatibleDC(pDC);
CBitmap *pBitmap = dcCompatible.SelectObject(pointer_to_CBitmap_object);
dcCompatible.LineTo(...);
pDC->BitBlt(0, 0, width_of_bmp, height_of_bmp, &dcCompatible, 0, 0, SRCCOPY);
dcCompatible.SelectObject(pBitmap);

Google shows a few implementations. But nothing really drop-in ready.

Hello!
I've a problem, i can't show a CStatic in my Dialog!
this is my code:
On OnInitDialog()
<br />
CBitmap m_bmp;<br />
BOOL res = m_bmp.LoadBitmap(IDR_BMP_NEW2);<br />
if (res) MessageBox("Image ok")
<br />
CStatic myStatic;<br />
<br />
myStatic.Create(_T("my static"), <br />
WS_CHILD|WS_VISIBLE|SS_BITMAP|SS_CENTERIMAGE|WS_BORDER, CRect(10,10,150,50), this);<br />

when i launch my app, there is nothing on Dialog
plz, help me! thanks

I think the problem is due to the fact that your CStatic is a local variable... so it gets destructed at the end of OnInitDialog... declare as a member of the class and you will have more luck!

thanks very much!
it's ok, i must declare CBitmap and CStatic like a varible of class.
thanks!

Definetely a compliment... You and hatsAlok are doing a terrific job!
Yes I hate the voting system as it is... if you vote 1, you should have to justify it (or at least lose your anonymity)...

can we send mail thourgh program or code in vc without the local smtp server on that machine
ddd

Yes, since SMTP is a *network* protocol. Providing there's an accessible SMTP server that the machine can connect to, there's no real difference (firewall/security measures aside) from communicating with a server on the same machine or a remote one.

SMTP has big problems nowadays because of spam!
The AOL SMTP servers for example do not allow receiving from dynamic ip addresses, so it is often better to use SMTP servers in the internet.
But theoretically you can create an own application instead of using a SMTP server, it's even possible to send and receive mails via telnet (connect to SMTP and type commands)!
Don't try it, just do it!

Hi,
Below is the part code, which used to display the frame from camera, my problem is that, can I create some button instead of by press "1"?
Thanks!
void CetCapConnect(HWND hwnd)
{
//CAPDRIVERCAPS CapDrvCaps; // structure of the capabilities of the capture driver
if (!hWndC)
hWndC = capCreateCaptureWindow ( // Create a child capture window
LPSTR) "My Capture Window", // window name if pop-up
WS_CHILD | WS_VISIBLE, // window style
0, 0, 160, 120, // window position and size
(HWND) hwnd, // handle of parent window
(int) 0 /* child ID */
);
LRESULT CALLBACK WindowFunc(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
HDC hdc; // handle of device context
switch(message)
{
case WM_CHAR: /* process keystroke */
hdc = GetDC(hwnd); /* get device context */
switch (wParam)
{
case 49: // pressed "1" to get connect
CetCapConnect( hwnd );
break;

hello everybody...
I'm trying to finish a report about a hooking program. I have some problems when I want to give a dialog at the caret position of others programs that users are typing on. Can you please give me any instruction to do that ?. For these problems, I want to get the caret position of any running programs. After getting the position, I'll show a dialog here.
<i'm vietnamese,="" so="" my="" english="" ability="" is="" limited.="">
Thanks....<vtalau>

When you say "caret," what exactly are you referring to? The mouse pointer can assume many shapes but a caret (^) is normally not one of them. If you want to know the position of the mouse pointer, check out GetCursorPos() and GetMessagePos().
