i have formated the message using the below method.
LPVOID lpMsgBuf;
FormatMessage( FORMAT_MESSAGE_ALLOCATE_BUFFER | RMAT_MESSAGE_FROM_SYSTEM,
NULL, dwError, MAKELANGID(LANG_NEUTRAL, LANG_DEFAULT),
(LPTSTR) &lpMsgBuf, 0,NULL );
CString strMessage = (LPTSTR)lpMsgBuf;
The error message is printed in the log file.
FILE *fp = fopen("C:\\log.txt","a+");
fprintf(fp,"\n Error Occured - %s ", strMessage );
fclose(fp);
in that log file it printer as
Error Occured -

Hi,
Thanks for your reply...
If I tried this application the VS2005 machine it is working fine.
But when only .net2.0 framework I got the visual c++ runtime library pop-up error
I tried the following as suggested by you:
1. I have installled the redistributable package suggested by you.
after installing i restarted the PC even now also I got the same runtime pop-up error.
2. Then I checked even with the dependency walker for the dll.
I found that there is no miising dll.
3. Then I tried by installing Visual C++ express edition..even then also i got the same pop-up error.
Kindly help me.....

LPDWORD lpdwDisp = &dwDisp;
CString l_strExampleKey = "SYSTEM\\CurrentControlSet\\Services\\USBSTOR";
CString l_strDWordSample = "Start";
DWORD dwVal = 4;
LONG iSuccess = RegOpenKeyEx (HKEY_LOCAL_MACHINE, "SYSTEM\\CurrentControlSet\\Services\\USBSTOR", 0L, KEY_READ , &hKey);
if(iSuccess == ERROR_SUCCESS)
{
RegSetValueEx (hKey, l_strDWordSample, 0L, REG_DWORD,(CONST BYTE*) &dwVal, sizeof(DWORD));
}
RegCloseKey(hKey);
Plz help me

}
If RegSetValueEx fails, you can find out why by calling FormatMessage() with the FORMAT_MESSAGE_FROM_SYSTEM flag.

hi i have class
<br />
class abc<br />
{<br />
public:<br />
abc()<br />
{<br />
}<br />
void disp()<br />
{<br />
}<br />
};<br />
int main()<br />
{<br />
abc *c = 0;<br />
c->disp();<br />
return 0;<br />
}<br />
here for c is memory allocated. and can i access class methods from c.

No..
BTW Why you want to do it?

i have to nothing but only i wanted to know weather we can access class functions like this is it possible.
|
|

No. You didn't create any instance of the object and you try to access a NULL pointer, thus this will crash. You have to create an instance either with new or this way: MyClass a;.
Anyway, this is really the basics so before going any further, I suggest you read a good book on C++.
|

Just as a thought, if you need to access the member functions before creating an instance of the class you could define the function as static. That way if you needed to call the function, you could write abc::function();. Just realize that any member variables that the function needs will also have be declared static and at this point, you might as well not wrap the function in a class at all because it is sort of pointless. However, it is possible.

Even though it is not a standard way, such function calls are possible if the function disp() is not accessing any of the member variable of class abc. If it is accessing any member variable inside it, the execption will occur at that point.
But the point is, if we didnt access a member variable in a member function of the class, why make it member function...?Static or global is enough..

You need to put one more requirement on that Naveen: it cannot be a virtual function since the virtual table goes with the instance of the object.
But, as you said, it serves no point making it a member function even though it will compile and run. It would be extremely poor design.
