See, for instance: "An In-Depth Look into the Win32 Portable Executable File Format" (have a look at "Relative Virtual Addresses" section).

Hi All,
I am beginner to MFC programming. I created one CLR Console Applications project, here in this project I want to use MFC classes like CString,CArray,CFile....etc.
In project settings I used "Use MFC in a shared DLL"
And in project stdafx.h file I am adding
#include<afx.h>
I also used few classes from MFC in the application and complied, I am not getting any errors.
But while running the application, I am facing crash in the application. and the error message is as follows
An unhandled exception of type 'System.AccessViolationException' occurred in Unknown Module.
Additional information:Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
Please provide some solution for this.
Thanks in advance.
Regards,
Kumar

You shouldn't need to use the MFC classes in the application.
CLR provides several classes for the same like String, Array, File etc.

How are you writing to the first 2 columns?

I am using Excel Automation for that.. but i am trying to close the excel file and then open it again in a different function and then i am trying to append it again. that is not happening. I am using PutElement function to write the values into the excel file. but i am getting an exception there.

Hi,
I am developing a application in pure win32. I want to set font for Static control. How can I do this?
|
|
|
|
|
I think you can use SetFont() function in MFC and use WM_SETFONT message for pure Win32.
|
|
|
|
|
Just to expand on Rajeesh's answer, read up on CreateFont, CreateFontIndirect, as well as WM_SETFONT.
Don't forget to keep the HFONT somewhere to tidy up after the static control is gone.
To get the font, I'd recommend SystemParametersInfo[^], as that filld in a structure with various fonts the system uses. That way you can keep the look and feel consistent.

I guess he may use the WM_GETFONT message for the purpose...

Not if the static window has gone *poof* he can't...
I'm always happy for people to ignore my advice though - as long as they've thought about it before rejecting it. After all, it does not always apply! (see your sig for more details)

Send the WM_SETFONT [^] message.

Hi all
I have a program written in VC6 (running on XP) that I want to stop from having multiple copies open. I want it to check whether there is another instance of itself running on start up and close if there is. Using FindWindow() doesnt work as it finds itself!
Thanks for any help

Consider creating a global named mutex.
Each app does this:
1) Create mutex -- give it a unique name, possibly including a GUID
2) WaitForSingleObject -- to capture the mutex. If this fails, then there's someone else holding it.
On exit, ReleaseMutex() to give it up -- and make it available again.

You can try creating a named mutex with CreateMutex() API and checking the result with GetLastError(). When the second instance of the app tries to create it, GetLastError() will return ERROR_ALREADY_EXISTS as the mutex is already created by the first instance.

Use this code..
if(NULL!=:CreateMutex(NULL,TRUE,_T("SingleInstanceApp")))
{
long DwError = ::GetLastError();
if(dwError == ERROR_ALREDY_EXISTS)
EndDialog(IDOK)
}
Hope it helps
