MSFLXGRD problem in 64bit machine (MFC/C++)
-
I am working on a 64 bit system (windows XP).I have a problem in launching an MFC dialog, that contains an active-x control (MSFlex Grid control).My project builds successfully without any errors.But when i try to launch this dialog, i get an error "Debug Assertion Failed".My Msflxgrd.ocx file is registered successfully.I don't understand where the problem is.Do let me know where the problem is.Please help me out ...... Thnx in advance. :(

This problem can arise if the dialog application is build for x64 and the flex grid is a 32 bit activeX.

Firstly, thnx for the reply. I have a question, though...if i am working on a 64bit machine, then the active x control (Msflxgrd.ocx) will be for 64bit right?How is it possible that i can built a dialog for 64bit with 32 bit active x control?Is there anything else that is required to be done on my project settings or any other file that i am suppose to use or download.Please do lemme know. Thnk You.

It is not necessary that the flex grid is also 64 bit. Even though the OS is 64 bit, you can create 32 bit binaries. Basically a 64 bit binary cannot load any 32 bit modules (.dll, .ocx etc.) Similarily 32 bit binaries cannot load 64 bit modules. So make sure the dialog app and flexgrid have the same bitness.

I have checked my dialog app and flexgrid.Both are 64bit. I don't just understand what the problem is.Please do let me know.
If you can give me the stack trace and the code in you
InitDialogfunction I could try and find out.«_Superman_»

Hi.... My code is pasted here below.I developed this in VS 2005, type of project: MFC Application(.exe) When i debug the code, it fails in function CreateDlgIndirect (in dlgcore.cpp which is system file) Please do have a look.Thnx again. BOOL CMFCExecutableApp::InitInstance() { // InitCommonControlsEx() is required on Windows XP if an application // manifest specifies use of ComCtl32.dll version 6 or later to enable // visual styles. Otherwise, any window creation will fail. INITCOMMONCONTROLSEX InitCtrls; InitCtrls.dwSize = sizeof(InitCtrls); // Set this to include all the common control classes you want to use // in your application. InitCtrls.dwICC = ICC_WIN95_CLASSES; InitCommonControlsEx(&InitCtrls); CWinApp::InitInstance(); if (!AfxSocketInit()) { AfxMessageBox(IDP_SOCKETS_INIT_FAILED); return FALSE; } // Initialize OLE libraries if (!AfxOleInit()) { AfxMessageBox(IDP_OLE_INIT_FAILED); return FALSE; } AfxEnableControlContainer(); // Standard initialization // If you are not using these features and wish to reduce the size // of your final executable, you should remove from the following // the specific initialization routines you do not need // Change the registry key under which our settings are stored // TODO: You should modify this string to be something appropriate // such as the name of your company or organization SetRegistryKey(_T("Local AppWizard-Generated Applications")); LoadStdProfileSettings(4); // Load standard INI file options (including MRU) // Register the application's document templates.

I would like to see the code where the actual crash happens. I'm guessing this is the code where the dialog or form view is being initialized.

Hi..... Thnx for the reply.I have pasted the code below from dlgcore.cpp.The code fails at function CreateDlgIndirect.Do have a look. If possible plse create an MFC Application in VS 2005 and insert an active x control (MS FLEX GRD) and execute it.i think you might get the error "Debug Assertion failed", while executing the dialog.to remind, my system is a 64bit system .Thnx once again.Please do let me know if you get to know the problem. thnx.
