Hi.
I am really confused why the layout on an English version and that from anotehr OS (Chinese etc) would display differently. THe other OS would display everything in a smaller area than teh ENglish OS leaving more empty space.
In the CformView dialog, I made sure that the FOnt size and type (10, MS Sans Serif - should be on all computers) are common so that the layout as I would see it on my computer "should" be what someone would see it on another computer.
I know I ma definitely missing something. Can someone help and give a few hints on how to deal with this?
Thanks in advance!

Hi,
how did you create your font?
There is two possibilities that more or less "ensures" you compatibility
BOOL CreatePointFont( int nPointSize, LPCTSTR lpszFaceName, CDC* pDC = NULL );
but here the "int nPointSize" can depend on the MAPMODE, is not the same MM_TEXT as MM_LOMETRIC (for example)
The other one (from Roger Allen's http://www.codeproject.com/printing/printingtricksandtips.asp[^])
CFont font;
LOGFONT lf;
::ZeroMemory (&lf, sizeof (LOGFONT));
lf.lfHeight = -MulDiv (12, pDC->GetDeviceCaps (), 72);
strcpy (lf.lfFaceName, "Arial");
if it works for printers, it should work for displays too.
EDIT:
I found this article.
http://msdn2.microsoft.com/en-us/library/d8ws31ff(VS.71).aspx[^]
I hope it helps

Hello,
In the InitInstance function there is statement by default.
if (!pFrame->LoadFrame(IDR_MAINFRAME))
return FALSE;
now instead of IDR_MAINFRAME I made another menu IDR_PLAN and loaded this frame instead of IDR_MAINFRAME.
When I execute the application I get debug assertion failure.If I Ignore the error I get my menu and I can continue with the application.
How do I get rid of this debug assertion failure?
If I want a particukar menu option to be grayed or to be active in a frame .How do I go about doing it ?
A different menu has to be made for grayed menu option and a different menu for the same menu option when it is active has to be made.And they have to be chosen whenever that particular event occurs. Is it?
Thanks
Pritha

This is how I am controlling the Menu Bar from the View Class Window. I hope this will help you.
void CMyApplicationView::OnFormatWordwrap()
{
// TODO: Add your command handler code here
CMenu* pMenu; // Create a pointer to the current menu.
CWnd* pParent = GetParent();
pMenu= pParent->GetMenu(); // Get the menu.
CWaitCursor wait;
if (pMenu->GetMenuState(ID_FORMAT_WORDWRAP, MF_CHECKED))
{
SetWordWrap(FALSE);
pMenu->CheckMenuItem(ID_FORMAT_WORDWRAP, MF_UNCHECKED);
}
else
{
SetWordWrap(TRUE);
pMenu->CheckMenuItem(ID_FORMAT_WORDWRAP, MF_CHECKED);
}
}
The code is self explainatory.
Please try to be specific in asking question if you want exact solution.

Hi,
I have a MultiView application. I have set the menus as follows.
BOOL CFPSApp::InitInstance()
{
SetRegistryKey(_T("Local AppWizard-Generated Applications"));
LoadStdProfileSettings(5);
pDocTemplate = new CMultiDocTemplate(
IDR_FPSIITYPE,
RUNTIME_CLASS(CFPSDoc),
RUNTIME_CLASS(CChildFrame),
RUNTIME_CLASS(CFPSView));
AddDocTemplate(pDocTemplate);
pParamInTemplate = new CMultiDocTemplate(
IDR_VIEWTYPE,
RUNTIME_CLASS(CFPSDoc),
RUNTIME_CLASS(CChildFrame),
RUNTIME_CLASS(CParamInView));
AddDocTemplate(pParamInTemplate);
}
And with this is the CChildFrame the one that automatically associates menus to respective classes/views.
I hope it helps you

Hello,
I need to add docking support in a dialog based application. Is this possible? (I could not find explicit examples here in CodeProject, most of the examples are for a Single or Multiple Document application and not for a Dialog based application.
The docking child window contains several combo boxes and a graph control, this window should be attached to some location in the main dialog window, but can be also "detached" as a modeless dialog.
I guess that the child dialog should derive from a CDialogBar...but what to do on the main dialog?
Another limitation: I can't use an ActiveX control to contain the docking window as in this example:
Docking CSizingControlBar objects inside ActiveX containers[^]..
Can someone provide some hint on how to do this?
Thanks in advance.

I add a class in my VC2005 project. I select the class template to be MFC and automation enabled. I want this class to be derived from CCmdTarget and handle some of the connection point events. The wizard created cpp file has a dispatch map.When I try to add methods to thjis class I do not find the dispatch map getting filled up. Is there anything I'm missing here?

You can always add them by yourself, although you don't find it in the Class Wizard. Try with a new project and another class that you now it has this message in class wizard. Put it in the new project to see the form and copy it to your project. Most of times it should work, as long as you don't ask something imposible to that class.

What is the difference between
a::a()
and
a::a(void)
Do we enforce some kind of extra information by use of the void keyword?

They are the same. The C language requires functions with no parameters to have the void. A lot of people have carried that over into c++

hello!!!!!!!
i have two listboxes and two buttons to move the content from one listbox to another.when i select an item from a listbox ...after clicking on button it moves to another listbox....but selected item remains selected in previous listbox.
our requirement is ....item remains in previous box but unselected.
thanks!!

You can do this by sending a message to the previous ListBox;
Use the SendMessage API as follows:
SendMessage(hWndControl, LB_SETCURSEL, -1, 0);
where hWndControl is the window handle to the previous ListBox. Setting the wParam to -1 means that there is no selection in the ListBox
Hope this helps!

Hi,
why don't you use the CWnd::SetFocus ()? As CListBox derive from CWnd you can use inheritance**
**is that the english word?

MessageBox(CString("Please Select a File."), CString("Properties"), MB_ICONASTERISK);
return ;
}
SHELLEXECUTEINFO sh={0};
sh.cbSize = sizeof ( sh );
sh.fMask = SEE_MASK_INVOKEIDLIST;
sh.lpVerb = CString("properties");
sh.lpFile = strFile;
ShellExecuteEx(&sh);

But this is working in VS 2003 but not in VS 2005. Can anyone help me what needs to edited.

What do you mean by not working? Not compiling? Not executing? Runtime error? 
Shog on learning VB6: Ah, that would have been VB6. Kicked my ass anyway.
So easy to learn, just like falling down a flight of stairs...

Hi Brahmma,
It was compiling and executing. But program was terminating abnormally when calling that function. Sorry for asking incomplete question.

That's fine; did you try debugging? Where does the crash occur?
Anything I will say you will bring it down to whatever you want.

Modify this to,
CString sVerb = _T("properties");
SHELLEXECUTEINFO sh={0};
sh.cbSize = sizeof ( sh );
sh.fMask = SEE_MASK_INVOKEIDLIST;
sh.lpVerb = sVerb;
sh.lpFile = strFile;
ShellExecuteEx(&sh);

I have such a function:
template <class t=""> T& GetInst()
{
static T t;
return t;
}
I'm not sure whether this is thread safe? If T's constructor has many operations, when two thread entered this function early and later, is there such scenario: the first thread is in T's constructor's, the second thread define t again?

|

|

c++ itself has no concept of threads. static means one and only one, not one per thread
|
|
|
|
|
Hi,
Since the value of the locat static variable is stored on heap, per my opinion it should not be thread safe.

I think this depends upon the Template Parameter. If first thread invokes the function with class1 type and second invokes with class2 type then those two will be entering different constructors. Since template will generate 2 copies of template class, one for class1 and other for class2.

If the function foo() have a local static variable then its not thread safe.

So, how to make it safe? Use thread mutex: ?
A& foo()
{
Wait_Mutex(...);
static A a;
Release_Mutex(...);
} ??
This looks very bad performance!
