Hi,
I am trying to screen capture right click context menu. I am using GetMenu, GetSubMenu, and GetMenuItemInfo APIs to capture standard application menu. Now, I want to capture right click context menu, but I don't know how to get a handle to the context menu(HMENU).
Does windows generate a window message and put it on the message queue when the right-click context menu pops up? If so, could you give me some hints how to utilize the message to get a handle of the pop-up menu. If you have any tips, pointers, or samples how to do this, could you help me. Thank you very much in advance.

Hi,
I am trying to capture the content of Full-screen DOS console to a bitmap file. Here are the steps I am trying.
When the user opens up DOS console window, and does ALT+ENTER to go into Full-screen DOS mode. The user then hits PrintScreen Key. This copies the content of the Full-screen DOS into the clipboard in text format.
I am able to intercept the PrintScreen Key by implementing a keyboard hook. My question is how do I convert the text format data on the clipboard into a bitmap file? Can I store the text data in a buffer, create a bitmap, and draw text data on the bitmap? Could you give me some tips, pointers, or examples how to do this? Thank you very much in advance.

Hi,
I am doing an entire screen capture INCLUDING THE MOUSE CURSOR. For GDI function calls, the mouse cursor is automatically hidden. Therefore, I have to get a handle of the current mouse cursor and use DrawIcon to draw it onto the screen. After the screen capture, I have to invalidate the area where the mouse cursor is drawn so the drawn mouse cursor won't stay on the screen.
I am using InvalidateRect(NULL, NULL, TRUE) to redraw all the windows, but this results in a very serious screen flickering while capturing the screen. I cannot figure out how to invalidate only the area where the mouse cursor is drawn. Could you give me some pointers, tips, or samples how to achieve this with InvalidateRect function?
Thank you very much for your help.

Well, that call to InvalidateRect will invalidate all windows causing WM_PAINT messages to be sent to all of them, since the HWND is NULL. And the TRUE for the bErase means that when each WM_PAINT handler calls BeginPaint (directly or by constructing a CPaintDC) the WM_ERASEBKGND message will be sent as well, causing much flicker.
It sounds like you know where to draw the icon, so I would suggest that you have all the info you need to fill in these values - which window, a RECT corresponding to the icon location, and, depending on the nature of the window, perhaps FALSE for bErase, and things will be much smoother.

Hi,
I have a slight problem - I have created a subclassed control which I am using a a dialog. I have enable the scrollbars and set them to the correct size etc, and have implemeneted OnHScroll and OnVScroll. However, when clicked on the scollbars don't work - as if they are just static images. Right clicking on them in Win2K and then choosing one of the options, however, does work correctly. Any suggestions?
Thanks!

I'm hoping that I'm just overlooking an easy solution to this problem. I'm formatting some text in a CString, and need to insert newlines into that text -- I've tried using both '\n' and '\r', and their ASCII numeric equivalents. This text is then displayed in a CEdit control -- problem is, the newlines show up as those bold black boxes (the ones that usually mean "invalid character"), rather than as newlines. The CEdit/CStatic documentation doesn't seem to cover this -- is there an escape sequence I'm missing? The only way I've gotten it working thus far is to make the CString::Format() call span multiple physical lines in my code, which is a pretty hacked solution.
I'm sure this one qualifies as a stupid question, but if anyone has a solution, I'd really appreciate it. Thanks.

Yep, that was the easy answer I was missing. Thanks.

Hi,
If I use:
IDRS_TEST RCDATA
BEGIN
"A String"
END
In my Resource file I can't start my app on Win98 and get an error that the .EXE is corrupt. To be precise "(Win32 Error 11)". The same stuff works fine under Win 2000.
I've tried:
"A String",0 and "A String\0" and it makes no difference.
I've searched MSDD, Google etc. to no avail.
Any help much appreciated.

Ok, I've found the problem. Looks like you can't use a Resource ID >= 0x8000 on Win9x but you can on W2K. I'm sure I have encountered this in the dim dark past. I thought I was going nuts. Another 5 hours lost.

HI all,
I want to build a buffer in visual c++ that can store 110 mb of data. And when it is full, it can write all the data in a new file.
Does anybody know how I can make this buffer, or do you have some c++samples??? 
Thanks in advance.

I think that you are better off using a the memory-mapped file, the same architecture used by the windows swap file. There is a class that encapsulates this. I have not tried this class myself, but I use the memory mapped file extensively for in-memory databases and they are very good in performance.
http://www.codeproject.com/library/wfc/cmemoryfile.asp
has a class by Sam Blackburn that encapsulates this functionality. Looking at the page, I think it is very easy to use.

I have an app which as soon as I try and start it Windows 98 gives me "Could not execute. Program has incorrent format (Win32 Error 11)" when running. Then a second MsgBox "The MyApp.exe file appears to be corrupt. Reinstall the file, and then try again."
The same .exe works fine on Windows 2000 and used to work fine on W98.
I am at loss as to the cause and how to resolve it. I have added two new static libs recently and will work through the code and remove all calls to them and see if the problem goes away. I was using VC6 SP3 and have just upgraded to SP4, then did clean builds and still have the same problem.
Help.

Just an idea...
Do you use any UNICODE strings?
If you do, win9x get's kinda mad at you

Hi Anders,
Thanks for that. Your comment was just enough to point me in the right direction. I've recently added an RCDATA resource which is a string of 110 characters. This is causing the problem but so far I don't know why. It doesn't seem to be the length, as splitting it in two still causes the problem. I'll keep looking. Its great that this works fine on Windows 2000, but breaks Win98.
Thanks again.

Hi there,
I've got a dialog based MFC application that I wish to make resizable. The problem is that I have a CListCtrl and everytime I try to resize it in my overridden OnSize method using either SetWindowPos of MoveWindow my application complains. I trace the error to the IsWindow ASSERT in the SetWindowPos or MoveWindow function.
Since I've only recently moved to MFC from the relative ease of VB (where I'd just set the width and height porperties and be done with it) I'm feeling somewhat confused 
Thanks in advance.
Marc

There are a few classes on this site that already do what your tring to acomplish;

Sometimes, I have noticed your program can get some WM_SIZE messages quite early, prior to the child controls being truly created. You can test the window handle of your child controls for IsWindow() to be valid prior to moving them around in the WM_SIZE, and that might help.
