ShellExecute

What does ShellExecute return if it fails???

[The Hobo]

If the function succeeds, the return value is the instance handle of the application that was run, or the handle of a dynamic data exchange (DDE) server application.

If the function fails, the return value is an error value that is less than or equal to 32. The following table lists these error values:
0
The operating system is out of memory or resources.

ERROR_FILE_NOT_FOUND
The specified file was not found.

ERROR_PATH_NOT_FOUND
The specified path was not found.

ERROR_BAD_FORMAT
The .EXE file is invalid (non-Win32 .EXE or error in .EXE image).

SE_ERR_ACCESSDENIED
The operating system denied access to the specified file.

SE_ERR_ASSOCINCOMPLETE
The filename association is incomplete or invalid.

SE_ERR_DDEBUSY
The DDE transaction could not be completed because other DDE transactions were being processed.

SE_ERR_DDEFAIL
The DDE transaction failed.

SE_ERR_DDETIMEOUT
The DDE transaction could not be completed because the request timed out.

SE_ERR_DLLNOTFOUND
The specified dynamic-link library was not found.

SE_ERR_FNF
The specified file was not found.

SE_ERR_NOASSOC
There is no application associated with the given filename extension.

SE_ERR_OOM
There was not enough memory to complete the operation.

SE_ERR_PNF
The specified path was not found.

SE_ERR_SHARE
A sharing violation occurred.

Yes i just found those error codes, but how do I compare it...I tried the following but it didn't work....since it returns an HINSTANCE and compare it against a string...

#include <iostream.h>
#include <windows.h>

int main(){
    char path[MAX_PATH];
    
    cout<<"Input the file to be launched: ";
    cin>>path;
    if (ShellExecute(NULL,"open",path,NULL,NULL,SW_SHOWNORMAL)==ERROR_FILE_NOT_FOUND )
        cout<<"error";
        system("PAUSE");

return 0;
}

Try casting it as an integer.

#include <iostream.h>
#include <windows.h>

int main(){
    char path[MAX_PATH];
    
    cout<<"Input the file to be launched: ";
    cin>>path;
    if ((int)ShellExecute(NULL,"open",path,NULL,NULL,SW_SHOWNORMAL)==ERROR_FILE_NOT_FOUND )
        cout<<"error";
        system("PAUSE");

return 0;
}
