atoi(char*) may work,if it does not, try to convert charvariable to char*. sprintf may be right function.

In my SDI Application the following problem appeared all of a sudden: In the InitInstance function of the application class the following line
// Dispatch commands specified on the command line
if (!ProcessShellCommand(cmdInfo))
return FALSE;
causes the error:
Error creating empty document ! (Translation from german, so the english errortext may be slightly different)
Tracing into the MFC code the error happens in the function CWinApp::ProcessShellCommand at the following statement:
if (!AfxGetApp()->OnCmdMsg(ID_FILE_NEW, 0, NULL, NULL))
Does anybody else have had this problem and found a solution ???

This happens due to failure of creating frame window.
check your CMainFrame::PreCreateWindow function.
It may returning FALSE.
Narrow down the problem by commenting whole code in this function and un comment one by one.
You will definitely get problem.
else
carry the same check on OnCreate() function.

Oh such a sh*t. I had some old code in the views PreCreateWindow function which fails at the current version of the project. And so the creation of the view fails.

EnumWindows() will cycle through every single window on the machine. Your program should be in there somewhere. You need to provide EnumWindows with a function to call for each window handle. Then try using GetWindowText() or GetClassName(). Most times you can figure out which Window Text or Class Name you are looking for if you use Spy++ (comes with Visual Studio).
Hope this helps!

After redaing your messages, one of best idea is to save your current handle of window in some INI or registry at starting .. so that other application read it from that common location and perform teh required.. though it not good solution... but it's worth trying it

Is your application spawning additional threads?

Perhaps try sending winword the WM_CLOSE message with SendMessage(), and send your own program the message, as well.
Hope this helps!

Hi all,
It is more of a windows question than Visualc++ related.
My questions are regarding the windows display settings.
[1]How Can I set "large","small" fonts settings under windows.Iam using WinXp & If I go to ControlPanel->Display,(Darstellung Tab,Iam using a German wINxP),I see the font->Normal,Large & Extra Large.
Is this the place for setting large & small Fonts.If yes,I see it only as Normal,Large & extraLarge under my system.
[2]
If I go to Settings->advanced Tab,I see the DPI setting combobox containing,96 dpi,120 & userdefined value. What is this setting for & How is it related to the screen resolution....
Hope someone could clear up my mind..
Thanks...

Hi all..
I want to set some time for a menu tooltip before it appears when the cursor is placed on the menu item.For eg if i place my cursor on the menu item and i do not want the tooltip to appear immediately, instead it should appear after the time which is set.
How can i do that?

|
|
|
|
check it out,
void SetDelayTime( UINT nDelay );
void SetDelayTime( DWORD dwDuration, int iTime );
default time is 500ms.

thanx

Please do not shout, or fix your CAPS LOCK key on your keyboard.
As for your question, DDX_ is an MFC macro that maps one of the controls you have created in the resource editor (IDC_THIN_PEN_WIDTH) to the member variable (m_nThinWidth), so that you can access to the control using the member variable.
For advanced user, it is possible to mess with the MFC macros; however, unless you are trying to do some advanced code, if you have to change a macro, it points out a bad design. What are you trying to achieve exactely ?

about the caps lock if you felt it that way then iam sorry ,i just wanted to know wether we could do it or not.
thanx for the explanation.

The way to figure this out for yourself is to place a breakpoint on the DDX_ line, run your program in the debugger and step into the DDX_ code.
You will then see what DDX_ does, and with a little help from MSDN you can easily figure out how to write your own.

Hey guys
I have a simple dialog based MFC in which I have removed the title bar area from property of dialog as I want to show that dialog in fullscreen. Also I have opened another smae kind of exe. now when i terminate I want to terminate the other EXE also. But my both the EXEs don't have either classname or caption. So how to close it ?
For that first i need to find handle of the other EXE and for this i use FindWindow() function. Now it requires classname or caption. Is there any way to assigne classname or caption so that I can find that window.
Any idea....
Or is there a way so that I first assign window name to one of my window and at run time I can hide that caption. ?

AFAI, with GetWindowsText, you can retrieve the "name" of your window. The fact that you does not show the caption does not remove the member of the dialog class containing the name, it is only not shown.

HI,
IAM NOT SURE I HAVENT DONE IT BUT YOU MIGHT CHECK INTO THE INITINSTANCE() WHICH IS RESPONSIBLE FOR MULTIPLE INSTANCES OF AN APPLICATION AND SEE WETHER YOU CAN GET ANY HELP FROM THERE.

You can do some interprocess communication.
In the second application use RegisterWindowMessage() to register a custom user message, and capture that message using WndProc().
In the first application (full-screen), when you are exiting, register the custom message, then send it to all windows using:
::SendMessage(HWND_BROADCAST,id,0,0); //id is id of the message returned by RegisterWindowMessage().
The second one will catch it in its WndProc() then it can exit.
this is this.

Use ::SendMessageTimeout instead or your application might hang on the first app that is not processing messages - I can already see myself shouting this from the grave
