Thanks for your help.
I tried the below code:
MessageBox(NULL, "Before!", "Invalid Key", MB_OK | MB_ICONINFORMATION);
HINSTANCE hInst = ShellExecute(NULL,"Open","C:\\Winnt\\Notepad.exe","C:\\xxx.txt","",SW_MAXIMIZE);
MessageBox(NULL, "After!", "Invalid Key", MB_OK | MB_ICONINFORMATION);
For me the both Message boxes are displayed, but not the exe was not opening.
Plz help me

That's what the fourth argument (e.g., c:\xxx.txt) is for.

You can also use CreateProcess().

I have a try-catch block as follows
try
{
A();
}
catch(...)
{
}
When i was working with Visual C++ 6.0, any null pointer accessed within function A was caught by the above catch. But now after VS2005 conversion, the same catch doesn't handles null pointer access, and the program crashes.
Please suggest on the Project Setting to be changed for this to work.

Usually YOU have to check if the pointer is valid:
if(p!=NULL){
...
p->...
...
}
in this case you also can:
try{
if(p==NULL) AfxThrowMemoryException();
....
p->...
...
}catch(...){
}
hope helps

From MSDN :
Also, in Visual C++ 2005, all objects in scope when the asynchronous exception is generated will not be destroyed even if the asynchronous exception is handled. Under /EHs, catch(...) will only catch C++ exceptions. Access violations and System.Exception exceptions will not be caught.
Resolution :
You can use Yes With SEH Exceptions (/EHa) option.
To set this option -
Click the C/C++ folder.
Click the Code Generation property page.
Modify the Enable C++ Exceptions property

Hi,
I have a little Problem with a CFormView derived class. I am now using the CChildFrame to determine the size of the window by creating a new View dinamically. It works good, but now I have a little problem.
The new CFormView I'm adding has a lot of controls (All CEdits) with writing protection to give some information. The number of CEdits can be [1, 24] (both inclusive). I want to make the view-frame to have just the needed size and here comes the problem.
The frame is resized as I want to the size that has to be shown. But the surface of the CFormView is keeping the size it has in the resource editor (as the needed elements were 24), so scrollbars appear although the elements in the non visible area are hidden with ShowWindow (FALSE);
So, the question is... how can I change the size of the formular to adjust it to the size of the frame? I don't want my visible controls to be affected (compressed or something like that). Just the opposite of ResizeParentToFit (...) that makes changes in the frame to fit the view, but avoiding effects like SetScaleToFit (...) because the controls change the size.
Greetings.

I have "solved" the problem by using MoveWindow (...)
But the solution has been... to put the size in MoveWindow to size of frame + size of scrollbar. So the scrollbars are not visible anymore, and they doesn't affect my controls in any way.
But I would still prefer to do it correctly, this is just a trick (isn't it?) but works :P

In "ShellExecute" function the parameters we pass it to it is,
HINSTANCE ShellExecute(
HWND hwnd,
LPCTSTR lpOperation,
LPCTSTR lpFile,
LPCTSTR lpParameters,
LPCTSTR lpDirectory,
INT nShowCmd
);
in this "LPCTSTR lpParameters" is a post parameter or something else? can we pass post parameter through "ShellExecute" function?

Use that member for any command line arguments you wish to pass onto the exe.

There are many softwares will auto run when the Windows only startup!
So,I want to code a small program to turn off some software's autorun?
How should I do this task?Thanks.
GOOD LUCK.

Depending on the new entry of the software at the time of installation, some softwares add an entry in the Run folder in the Registry. If you know how to tweak the registry and modify the values so as not to run the software you know how to stop a software from executing at StartUP. Playing with the registry is dangerous and you should always have a backup of it before doing any changes.
Somethings seem HARD to do, until we know how to do them.

Programs can be started on 3 levels
1. In the starup folder of the user.
These are link files which can be deleted. I think you can find the folder with the function SHGetKnownFolderPath[^]
2. There are 2 places where programs can be starten from the registry
HKCU/SOFTWARE/MICROSOFT/WINDOWS/CURRENTVERSION/RUN
HKLM/SOFTWARE/MICROSOFT/WINDOWS/CURRENTVERSION/RUN
3. Last place: The services.
These program2/services can be started according to there startup settings: manual, automatic, disabled.
Hope this is helpfull
