Can anybody help me in copying AAComBSTR to BYTE. Is there any API available which does this copy. Your help is appreciated.

It crashes at EnterCriticalSection in below function of C:\Program Files\Microsoft Visual Studio 10.0\VC\atlmfc\src\mfc\afxcrit.cpp void AFXAPI AfxLockGlobals(int nLockType) { ---- ---- // lock specific resource EnterCriticalSection(&_afxResourceLock[nLockType]); ----- }

CCommandLineInfo cmdInfo; ParseCommandLine( cmdInfo ); // Dispatch commands specified on the command line if( !ProcessShellCommand( cmdInfo ) ) return FALSE;

We have migrated our application which was written in VC 6.0 to VS2010. The application crashes on launching it. The crash occurs at ProcessShellCommand( ). On debugging got this error "Unhandled exception at 0x7575d36f in MyApp.exe: Microsoft c++ exception CInvalidArgException at memory location 0x0012fb98" What could be the problem and possible fix for this. Thanks in Advance.

We have migrated our workspace from VC6.0 to VS2010. There is a CreateControl api which is returning 0 after converting to VS2010. Before conversion this was working fine. What could be the reason for failure.

The following piece of code was working fine in VC++6.0 . When UAC was enabled/disabled , for an administrative user the IsUserAdmin was returning true. We are migrating VC++6.0 to VS2010. After this when UAC is enabled IsUserAdmin is returning false and when UAC is disabled IsUserAdmin is returning true. Why is this failing in VS2010 when UAC is enabled and what could be fix for this. BOOL IsUserAdmin(VOID) /*++ Routine Description: This routine returns TRUE if the caller's process is a member of the Administrators local group. Caller is NOT expected to be impersonating anyone and is expected to be able to open its own process and process token. Arguments: None. Return Value: TRUE - Caller has Administrators local group. FALSE - Caller does not have Administrators local group. -- */ { BOOL b; SID_IDENTIFIER_AUTHORITY NtAuthority = SECURITY_NT_AUTHORITY; PSID AdministratorsGroup; b = AllocateAndInitializeSid( &NtAuthority, 2, SECURITY_BUILTIN_DOMAIN_RID, DOMAIN_ALIAS_RID_ADMINS, 0, 0, 0, 0, 0, 0, &AdministratorsGroup); if(b) { if (!CheckTokenMembership( NULL, AdministratorsGroup, &b)) { b = FALSE; } FreeSid(AdministratorsGroup); } return(b); } Thanks in advance

The exact path is LoadLibraryW("C:\\Program Files\\MyApp\\");

The dll is physically existing in the desired path. But still LoadLibraryW( ) fails.

We are calling LoadLibary in C#. For this we have included the below code in the C# file. [DllImport("Kernel32.dll")] internal static extern IntPtr LoadLibraryW([MarshalAs(UnmanagedType.LPWStr)] String lpMdoule); We have multiple LoadLibaryW( ) calls. All of them are passing , except one. We verified the GetLastError( ). It returns 126. But the dll is physically existing in the correct path. What could be the reason for dll failure.

The dll's which this dll is dependent are available in the appropriate locations. Also tried verifying them in dependencyWalker. There are no dependency erros seen in it. But still the LoadLibaryW call is failing.

My system has a directory C:\AAAA. Where 'AAAA' has security permissions set. ie., only read operations can be performed and no write operations. My application tries to create a directory under 'AAAA'. i.e, C:\AAAA\BBBB. I am trying to handle an exception to avoid a crash - try { Directory.CreateDirectory("C:\\AAAA\\BBBB"); } catch(Exception ex) { } But I am observing that the catch handler is never invoked. My application is trying to create the directory, It is unable to create and it goes to the next statement after the catch block. What would be the code to check whether a directory can be created under AAAA or not.
