Dialog creation may fail if the dialog template has a Rich
Edit control in it. This template may be used in a dialog, CformView, or
property page.
The following error messages may appear in the IDE
output window when you execute the program in the debugger with the debug
build. No error message or warning is given if you execute the program outside
the debugger or with the release build.

Dialog or Property Page
Visual C++ 5.0:
Warning: Dialog creation failed!
Visual C++ 6.0:
If this dialog has OLE controls:
AfxEnableControlContainer has not been called yet.
You should call it in your app's InitInstance function.

CFormView
Visual C++ 5.0:
Warning: Dialog creation failed!
Warning: could not create view for frame.
Failed to create client pane/view for frame.
Warning: CDocTemplate couldn't create a frame.
Visual C++ 6.0:
If this dialog has OLE controls:
AfxEnableControlContainer has not been called yet.
You should call it in your app's InitInstance function.
In the case of a CformView, the following message also
appears:
Failed to create empty document.
Back to the top
The Rich Edit control is not initialized.
Back to the top
Call the MFC global function AfxInitRichEdit before you
create the dialog to initialize the Rich Edit Control. A good place to
initialize the Rich Edit control is in the application's InitInstance function
before you create the dialog.
Back to the top
This behavior is by design.

With the new dialog editor in Visual C++ 5.0, it is
possible to add a Rich Edit control into a dialog template by dragging the
control from the control palette. However, doing this in the dialog editor does
not ensure that the required Riched32.dll library will be loaded before the
Rich Edit control is created. In Win32 SDK, it is necessary to call the
LoadLibrary function to load Riched32.dll before the dialog creation. In MFC,
the global function AfxInitRichEdit does this for you. All you need to do is
call this function before you create the dialog.
Please use the
online help to get more information on AfxInitRichEdit function.

Steps to Reproduce Behavior
Dialog Scenario
The follow scenario reproduces the problem described above with a
dialog.
| 1. | Create a new project as follows: File\New\Projects\MFC
AppWizard(exe). |
| 2. | Create a Dialog based application, and then click Finish. |
| 3. | Add a Rich Edit control to the main dialog template in the
dialog editor. |
| 4. | Build the application. |
| 5. | Press the F5 key to start the debugger. Notice that the
application does not display the dialog. |
| 6. | Observe the following in the Output window in IDE:
...
Warning: Dialog creation failed!
...
|
CformView Scenario
The follow scenario reproduces the problem described above with a
CFormView.
| 1. | Create a new project as follows: File\New\Projects\MFC
AppWizard(exe). |
| 2. | Create an SDI or MDI application and in step 6 of Appwizard
select CFormview as the Base class for the view. |
| 3. | Add a Rich Edit control to the main dialog template for the
formview in the dialog editor. |
| 4. | Build the application. |
| 5. | Press the F5 key to start the debugger. Notice that a
message box appears indicating that the empty document could not be created.
|
| 6. | Observe the following in the Output window in IDE:
...
Warning: Dialog creation failed!
Warning: could not create view for frame.
Failed to create client pane/view for frame.
