virtual ~header(); was just left in and will be removed - it is not needed or being used in this app... The class wizzard puts this code in on generation..in c style code they used structures instead of classes.. make a (class test) and a (struct test) in a .h file and save them - they are the same size.. so I create an array of the class for storing data.. It works like a data base or will once its complete..I guess it depends on the app- and if it works with no errors and no bugs since I removed that ios::nocreate- so far its working..
thanks again!

Hello,
I cant get my checkbox to work. Here is my problem.
I need to do this.
If the checkbox is check when I check it I need to uncheck the checkbox and if it uncheck when I press it I need to bring up a new dialog window. I cant get this to work.

Are you using MFC?

Via ClassWizard (Ctrl+W), provide a handler for the BN_CLICKED notification message. In it, call the button's GetCheck() method to get the checked state of the button.

Do you want it to be checked also? If so set the style to BS_AUTOCHECKBOX when you create it. Handle the BN_CLICKED command and use GetCheck() to see if the button was checked or unchecked.
You may be right
I may be crazy

Can you give me an exemple? And yes I want it to be checked.

Use ClassWizard to add a BOOL for the checkbox named m_bCheck. Double-click on the checkbox to add a handler. Populate the handler with code like the following:
void CMFCDialogDlg::OnCheck1()
{
UpdateData(TRUE);
if (m_bCheck)
{
AfxMessageBox(_T("Dialog goes here..."));
}
}

Hi
I have a dll with exported functions, which I protect with AFX_MANAGE_STATE(AfxGetStaticModuleState()). Fine. Now, to those functions I send a callback function as a param. This callback function is in the exe. Is there a corresponding way to restore the module state when I get back into the exe, or do I need to roll up my sleves for this one?
It's a requirement that the writer of the dll shouldn't be bothered with restoring the state before calling the callbacks, but just setting his own state correctly using the AFX_MANAGE_STATE macro.

Do you really need to do this? Are you accessing resources in the dll and the callback?
Mark
|
|
|
|
|
Yes. 
The dlls may supply dialogs, as well as calling one of the callbacks to invoke the exes dialogs (along with other things)
|
|
|
|
|
I would think you'd just need AFX_MANAGE_STATE(AfxGetStaticModuleState()) at the top of the
callback function.
As long as the module handle is set properly so MFC can find and load resources when it needs to.
This can also be overriden by loading the resources yourself if you need to.

I already tried that. AfxGetStaticModuleState() only seems to work in dlls. It returns null for resource and instance handles.
|
|
|
|
|
After some investigation I found that
AFX_MODULE_STATE* pPrevModuleState = AfxSetModuleState(NULL);
on entry, and
AfxSetModuleState(pPrevModuleState);
on exit seems to work. This will allow me to load the correct resources and also use AfxGetApp() and its compadres.
(though I'm not entirely convinced yet)
thanks for your time.

Hi all guys,
I've a big trouble with my application.
It's based on some lib that must be compiled using setting MD[DLL Multithread].
The application runs without problems on my two pc that have VisualStudio 2003 & 2005 installed.
But i tried it on a pc without any visualstudio and it cannot start:
it gives this kind of error:
"Impossible to start specified application. Application configuration is not correct. A new installation of application could solve the problem".
I imported mfc80.dll thinking that here was the problem...but it doesn't solve!
Please help

thank you very much!!
it solved the problem!

Is there some reason why, when I create a new dialog (CMyKeypad) that I get an error message from the Class Wizard stating:
"Unable to open the files (directory path) for class CMyKeypad".
Thanks

Can you manually (e.g. with Windows Explorer) create a file in that location?

Hi,
During the creation of the MainFrame, i call a function called StartUp,
which initialises different configs.
If something goes wrong during this initialisation, i would close the application.
an exit(1) terminates hardly the program and provokes MemoryLeaks ( Destructor isn't called )
Anyone an idea?
Thanks

Which means you should not be using exit(). Send a WM_CLOSE message instead.

So you are in (your CFrameWnd-derived class) CMainFrame::OnCreate?
Simply
return -1<br />
this is the official notification that the creation went wrong.
See the MFC-standard code:
if (!m_wndToolBar.CreateEx( this, TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_TOP
| CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC) ||
!m_wndToolBar.LoadToolBar(IDR_MAINFRAME))
{
AfxMessageBox( "Failed to create wndToolBar\n", MB_ICONERROR);
return -1;
}
