This article here:
support.microsoft.com/support/kb/articles/q155/9/18.asp
shows how to add scrolling to a CFormView. Its a short
paragraph of code. It works, but when I keep the program
with the scrolling open and then click another program,
I get an error at this line:
if (GetFocus()->m_hWnd == pWnd->m_hWnd)
the first line. It doesn't like the GetFocus() command.
Any ideas on how to get rid of the error. Please, any
response any one can give me will be greatly appreciated.
Sincerely,
Danielle (an overworked graduate student)

this is the text from msdn
A pointer to the window that has the current focus, or NULL if there is no focus window
so the statement GetFocus()->m_hWnd will fail if GetFocus returned NULL (memory exception)

Any code change recommendations. I tried alot of different
changes including:
if (GetFocus()->m_hWnd == pWnd->m_hWnd ||
GetFocus()->m_hWnd == NULL)
but I am not having any luck 
|
|
|
|
|
Its all wrong.
CWnd *pFocusedWnd;
pFocusedWnd = GetFocus();
if(pFocusedWnd->m_hWnd == pWnd->m_hWnd)

I meet a problem and ask for your help.The following is my problem:
CPU: PII, OS: Windows98.
When any process is ready to run OS I want first to suspend it. And then I want to resume the process which has been suspended as I will. Since in the Windows98 there is no other method to realize this function except the Win32 Debug APIs method I apply them to my program. I write a small Dialog Based project using VC++. When I click a Button on the dialog I create a thread named t1 to get the current running processes in the memory. And then there is a While() loop to get the current running processes. Whenever a new process is created in the memory t1 will find it and t1 will create a new thread t2 to debug the new created process using DebugActiveProcess() function. And then WaitForDebugEvent(), ContinueDebugEvent() and so on. Here comes the problem. Sometimes t2 works well. The new process is suspended and resumed. But sometimes when a new process is starting up it is found by t1 and t1 creates a new thread t2. Then t2 suspends this new process using DebugActiveProcess() function and all these steps succeed, but WaitForDebugEvent() function fails and it returns zero and zero again in the loop. Here the new process is suspended for ever. I don't know what is the matter. It seems that t2 don't receive any debugging event occurring in the process being debugged. I don't know why. I have found that whenever this error occurs and the new process is suspended for ever there are always only 2 threads in the new process being debugged. My analysis is that one thread belongs to the new process and it is the main thread and the other thread belong to the system. Although the other thread is in this new process it is created by the system. This thread reports the debugging event occurring in the debugged process to t2, but why t2's WaitForDebugEvent() fails. This is very strange. Could you give me some suggestion and help me solve this problem. Thank you!
If I don't describe my problem clearly I could express it clearly later.

Is it possible to redirect the stderr or cout stream to a file instead to the console?

Try running a search on CP for "Redirect"

Help me, i need to print more pages in different mode, for example i want print the first page in orizontal mode and the second page in vertical mode and see that also in printpreview.
sorry for my english....
|
|
|
|
|
nevermind, my english is certainly more bad than yours... 
i don't really know how we can specify to the printer the orientation of the page, but i know many useful dialogs are already created by/in windows. what you have to do is to search how to call these dialog boxes
see you later Mr redking74...
(just for my general culture ( ), what does the 74 in your nickname reprensent ?)
thanks

There is no easy way to do this in a single print job. You could either:
1. Print 2 jobs with one in portrait and the 2nd in landscape
2. Write your print function so that it renders the 2nd page of output rotated by 90'. This wil lhave to effect of showing the page rotated also in preview mode.

I have thinking at this method but i have failed.
Have you a code for this particular type of print?
Thank' s Rogen Allen
|
|
|
|
|
Which is the type you want example code for?
1. Multiple print jobs (fairly simple)
2. Rotated output (difficult)

I have a SDI project and the view is CScrollView. I draw a rectangle on the it, then the graphic will be zoomed in/out.
When the rectangle is magnified as enough, some part of the rectangle will not be displayed on the view, because the ScrollView are not be magnified sychronously, WHAT I want is that I can see the whole part of the graphic when it is magnified, so the ScrollView has to be magnified sychronously. how should I do?
Thanks for any help!
void CEx02View::OnInitialUpdate()
{
CScrollView::OnInitialUpdate();
CSize sizeTotal;
// TODO: calculate the total size of this view
sizeTotal.cx = sizeTotal.cy = 1000;
SetScrollSizes(MM_TEXT, sizeTotal);
}
the ScrollView has set to size(1000,1000).
To zoom in/out:
pDC->SetMapMode(MM_ISOTROPIC) ;
pDC->SetWindowExt(100, 100) ;
pDC->SetViewportExt(200, 200) ;
//IF I change the parameters as below,
//pDC->SetViewportExt(2000, 2000) ;
//Some parts will be cropped.

Hi Guys,
Iam displaying overlays to screen using the DeviceContext.I display it to screen by calling the "PlayEnhMetaFile" Function.Everything worked fine until I Tried to load an emf File which contains slanted Lines(Iam attaching the file also along with this).When I run my application & load this Emf file everything is fine.But when I scroll the emf file using scroll bars,the lines appears like ZigZag,not slanted any more.
Any idea what could be the cause...
Thanks..

|
The Lines appear Zigzag only when the image disappears from the clientarea while scrolling...

sir,
I am making my own custom controls using subclassing technique in core Win32 programming. But problem is that I don't know the solutuion for message reflection in Win32 programming. Message Reflaction is provided in MFC but how to do that in Win32 programming. I have heard to use FORWARD_ message crackers but how to use that I don't know. So tell me how to do this in win32 so that message sent to parent window procedure will automatically transfered to my child window procedure where i can handle it.
|
|
|
|
|
As far as i know that the message reflection is a functionality of MFC not in generic windows messageing.
I guess FORWARD_WM_NOTIFY this macro may help you.
