Win32 CreateProcess Help

Change the line
TCHAR * processPath=_T("notepad.exe");to
static TCHAR processPath[]=_T("notepad.exe");

The documentation for CreateProcess says that the lpCommandLine parameter must be an LPTSTR, in other words pointer to modifiable char buffer, and that in the unicode version it really modifies the buffer (I have no idea why.) Since string literals are stored in read-only memory, the program was getting an access violation when trying to write to this literal.

One more comment. I found a very nice article here (http://www.possibility.com/Cpp/const.html) (search for "Const Storage and String Literals").
It claims that the reason C++ Standard allows assignment of string literal to non-const char array is to support existing incorrect code base.
Sounds reasonable...
However, it will be a great practice to always useconst TCHAR * processPath=_T("notepad.exe");I wonder if there is a way to generate at least a warning for these non-const assignments?

Hello once again !

Thanks to all of you (especially googler) from the bottom of my heart !! I failed to understand the reason why it is giving such exception... anyways ! thanks once again !

Well, you're correct that it doesn't say "fail to compile". But it says that there is a breaking change because "String literals now have the type const char []". From that I inferred that the following line should faile to compile:
// why isn't this an error (const / non-const mismatch),
// if "notepad.exe" has type const char []?
TCHAR * processPath=_T("notepad.exe");

FOr example, the following code does not compile on Comeau:
int main()
{
const char test_c[] = "Test";

const char* testp_c = test_c;
char* testp_nc = test_c;

return 0;
}

Output:

So, I must have read too much into the "breaking change" part of this cite.
