I'd imagine it's declared extern in some header file you're including in all your source files. I'm not that familiar with Qt, so I don't know where you'd look.

In C++. yes.
You need to declare extern to tell the compiler to look for the global variable in the obj files.

Hi,
I have an MFC application were in a View i dynamically create a set of Controls(Edit,Button etc).At one point i want to destry all the controls created in a view and create new controls.I am using destroy() window to destroy controls before displaying 2nd screen.
But both the screens are messed up..Controls are not deleted on calling Destroy()..Pls help
Thnks

Perhaps it would be easier to design two classes derived from CFormView, one carrying the first set of control, the other one the second set.
You could then replace the views as needed.

Hi all
How i can to get color of pixel on my device context.
I get device context of my dialog box sucessfully and fill necessary rect by black color (COLORREF cr = 0x00000000).I watch so it was succesfully too.But when i get color of pixel from this rect by GetPixel routine it functiont retreive me unexpexcted color (not black)
Why???
Thanks.

The GetPixel() API expects screen coordinates, not client. You should call ClientToScreen() for your rect before calling GetPixel().

we are developping a screen capture app, but it is too slow.
the steps are:
1. get WindowDC or screen DC
2. create compatible bitmap and DC
3. call BitBlt function to copy image to compatible DC
4. GetDibits of compatible bitmap then save it to a file
the problem is:
step 3 is too slow (over 200 ms), we need to get all info in 30 ms.
we believe that there must be other ideas to do that, because we know many capture apps work very well.
do u have another idea or how to let it work faster ?
thx in advance

This article may or may not be close enough to what you need. It does something entirely different but may trigger some ideas.

Just an idea:
Did you try simulating PrintScreen and grabing from ClipBoard (if allowed)?

It worked for me. Are there any articles on Menu Handling apart from MSDN examples.

 Problem on porting from VC 6 to VC 7 - context sensitive help [Shift F1 Help] - using Onhelphittest()
OnHelpHitTest() return dialog contol ID to MFC and MFC calls COurWinApp::HtmlHelp()
Which is processed. and appropriate help is displayed. In VC7 MFC isn't calling COurWinApp::HtmlHelp()
HtmlHelp() function is not called instead gives "Failed to launch help" message.
Code Snippet below
------------------------------
To implement Shift F1 help for COurDlgCtrl
#1. we added
LRESULT COurDlgCtrl::OnHelpHitTest(WPARAM wParam, LPARAM lParam)
{
return GetDlgCtrlID(); // Nonzero value
}
#2. Then we added this
void COurWinApp::HtmlHelp(DWORD dwData, UINT nCmd )
{
DWORD HelpID = -1;
WORD wCtrlId = LOWORD (dwData);
WORD DlgCtrlId = HIWORD (dwData);
HANDLE hHtmlHelp;
// Map the Dialog Control IDs to corresponding Help IDs
switch (nCmd)
{
case HELP_CONTEXT:
switch (wCtrlId)
{
case OurDlgCtrlID:
HelpID = IDH_TEMPDLG_DRAG;
break;
default:
HelpID = -1;
}
hHtmlHelp = ::HtmlHelp(NULL,
m_pszHelpFilePath,
HH_HELP_CONTEXT,
HelpID);
}
}
For VC 7 migration
#3. We added EnabeHtmlHelp() in constructor of COurWinApp.
This still doesn't seem to work.
HtmlHelp() function is not called instead get "Failed to launch help" message.
Thanks in advance

Please explain, as MFC files are DLLs, not EXEs. Are you saying that programs built with MFC are causing the system to halt?

Hi,
I'm looking for some kind of "VC6 project templates" - i.e. generate the same settings based on an existing .dsp, with a new name etc., but keeping compiler/linker settings, project configurations, etc.
I looked into custom appwizard, but it only generates default configurations.
[edit]I figure a tool where I can pre-configure a search-and-replace, *including* S&R in file names, could dothe job...[/edit]

I never seemed to be able to get it to work when it generates from another project properly either.
Alternatively, create a default project *similar* to what you want (MFC / DLL / Console), then add the source code, you can then use the text from the 'project->settings->link->project options' and 'project->settings->compile->project options' edit boxes to rebuild your compiler options.
I've found that custom appwizards can take quite a while to get exactly right - so if you can use a find and replace for a one off, do that instead.
Some Gotcha's for Custom Appwizards
in 'void CYourProjectAw::InitCustomAppWiz()' make sure that the dictionary sets the correct type of project. For example,
m_Dictionary[_T("PROJTYPE_CON")] = _T("1");
in 'void CYourProjectAw::CustomizeProject(IBuildProject* pProject)' you can set all the compiler options. MSDN / VC6 samples are the best source of info for this. It can be really painful to do this right, because it has to be done for the debug and release builds.
