Hi friends,
I had tried to stretch a Gif image and unable to do
My code is :
CImage image;
HDC dc = GetWindowDC()->GetSafeHdc();
BYTE *m_buffer;
CFile file;
if( !file.Open( MAKEINTRESOURCE(IDR_GIF1), CFile::modeRead) )
return false;
long m_buffer_size = (long)file.GetLength();
m_buffer = new BYTE[m_buffer_size];
if ( file.Read(m_buffer, m_buffer_size) != m_buffer_size )
return false;
file.Close();
IStream *pIstream;
CreateStreamOnHGlobal(NULL, TRUE, (LPSTREAM*)&pIstream);
ULARGE_INTEGER ulnSize;
ulnSize.QuadPart = m_buffer_size;
pIstream->SetSize(ulnSize);
LARGE_INTEGER lnOffset;
lnOffset.QuadPart = 0; //starting location is 0
pIstream->Seek(lnOffset, STREAM_SEEK_SET, NULL);
ULONG mysize;
pIstream->Write(m_buffer,m_buffer_size,&mysize);
image.Load(pIstream);
CRect rectDest;
rectDest.top = 0;
rectDest.bottom = 50;
rectDest.left = 0;
rectDest.right = 50;
image.StretchBlt(dc, rectDest, PATCOPY);
image.Draw(dc,0,0);
Kindly help me .. 
Thanks in Advance..

Try SRCCOPY rather than PATCOPY?

OK, here's the answer I was going to give you before I realised that PATCOPY doesn't work and SRCCOPY does (by trying it).
You have a whole load of steps - any one of which could be failing. You don't check returned status codes - any one of them could be failing and you don't know. So, try adding some error checking so you know what's going wrong.
Also, what's with the IStream and HGlobal stuff? You don't need that to read a CImage from a file - here's the code I'm using in my OnPaint:
PAINTSTRUCT ps;
CDC * drawDC = BeginPaint(&ps);
CRect rcClient;
GetClientRect(&rcClient);
CImage image;
image.Load(_T(image filename));
image.StretchBlt(*drawDC, rcClient, SRCCOPY);
EndPaint(&ps);
Simpler, no? Simple's good.

hi guys!
I currently need a modeless dialog in wich i need this behavior.
The modeless dialog shows, and then if i click it's parent will bring the parent dialog to top most. But i can not achieve this behavior, i create the modeless dialog but when i click the parent window it becomes active but the modeless child window stay on top.
I tried to use setparent but my app crashes. i am using something like this:
<pre>CMydialog * dialog = new CMydialog();
dialog->Create(IDD_DIALOG);
// dialo->SetParent(this);
dialo->ShowWindow(SW_SHOW);</pre>
but when i uncomment setparent it crashes. Please someone help me, i am a noob in this!

Try this,
In .h file
......
CMyDialog* dialog;
.....
In .cpp file
.....
if (dialog != NULL)
m_pDlg->SetFocus ();
//
// If the dialog box doesn't already exist, create it.
//
else
{
dialog = new CMyDialog;
dialog->Create (IDD_OPTIONS);
m_pDlg->ShowWindow (SW_SHOW);
}
|

Thanks dude!
But i know now how to do what i asked for, is use the desktop window like it's parent
dialog->Create (IDD_OPTIONS, GetDesktopWindow());
and that´s it.

Hi,,
I have a file abc.reg.I want to install the registry file , but the main point is the RUN dialog as well as the conformation dialog should be hidden to the user. After shell execute the installation should be done silently.
Any help is appriciated.

You must use CreateProcess instead of ShellExecute.
Give the lpCommandLine parameter as Regedit.exe /s <.REG filename>

hi all,
I have made a dialog based application in vc2008...
my problem is when i run my application sometimes it gives an error
Window has triggered a breakpoint in program.
This may be corruption of the heap, which indicates a bug in program or any of the dll it has loaded....
This may also be due to user pressing F12 while Program is in focus.
The output window may have more diagnostic information...
and sometimes it runs fine....
my application runs in release mode so can't debug it....
how can i resolve my problem...
|
|
|
|
|
Why cant you run it in debug?
|
|
|
|
|
Run the application in debug mode and read here[^]
You need to google first, if you have "It's urgent please" mentioned in your question.

I have developed a Ribbon application on Vista using VS 2008. It works fine on Vista. I statically link MFC so that I can run it on XP too.
But when I run it on XP, it puts up a dialog box saying "A required resource was unavailble". Later if I press OK on this dialog, it puts up another one saying "Encountered an improper argument". Many such("Encountered an....") dialogs follow(one after another) until I terminate it from the task manager.
Interesting thing I noticed is that this scenario occurs when I just place the mouse pointer over the Ribbon bar. I do nothing else. Then I open the Task manager and see that the memory used is increasing by 8 Kbytes with every second. Eventually followed by the above scenario.

I solved the problem.
There was a resource leak in my code, but it was crashing in MS VC++ code.
I was getting the handle to dc(GetDC()) in some UI update event(ON_UPDATE_COMMAND_UI), but I was not releasing it.
