Editing resources
of RAD C++ controls
Do not edit them from
VC++ resource tab, rather open the resource file in VC++ editor using
file - open menu item and then edit them.
How
to Display document and application classes as forms
Note:
In Appwizard generated projects, RadVC only displays CWnd derived
classes as forms is to enable users to add RFC / RAD C++ controls in
them. In a document-view application, it is not very customary to add
C++ controls, especially visual RAD C++ controls in application and
document classes. To make your document and application classes behave
as forms, you manually need to do whatever RadVC does with CWnd -
derived classes. This includes adding function prototypes such as
CreateControls(..) etc. in your document and application classes. Once
the prototypes are added, refresh your active project using RadVC's
"Refresh Project Info", the application and document classes
should now show as forms.
What's the method of closing an application
programmatically ?
Use
(1) If you are in a
form's class use:
::PostMessage(WM_CLOSE);
(2)
From anywhere in the application, use: AfxGetMainWnd()->PostMessage(WM_CLOSE);
How can I Change a
Non-MDI Form to an MDI Form?
If you have
already started a project with the default form options (MDIForm
checkbox unchecked) but later decide to make the startup form an
MDIForm, then here is what you need to do:
(1) First, open
the header(.h) and implementation(.cpp) files of the forms. Change all
instances of base class of the form from CRForm
to CRMdiForm.
CRMdiForm is the RFC class that
implements MDI form functionalities.
(2) If your form
was created using "3-way RAD" option unchecked, then there is little
more work you need to do. First check if "3-way RAD" option was
selected while the form was first created [ Please check the next
Knowledgebase item to do so]. If it was created without "3 - way RAD"
option, then open the implemention file (.cpp) of the form and change
the line "m_nPropStringID = IDS_PROP_FORMXXX;"
to "m_rect = CRect(0, 0, 300);" With this
change, the form properties will be set to default, thus you may need
to change them again to their old values from the property window.
Please make sure
to
refresh your active project using RadVC's "Refresh Project Info"
option after you make the change.
How do I Know
if "3-way RAD" option was selected when a form was Created?
Open the
implementation file(.cpp) of the form and check the "constructor"
of the form class.
If your form was
created without "3 - Way RAD" option, then the constructor should look
like the following:
CForm1::CForm1()
{
//{{AFX_FORM_DATA_START
m_nPropStringID = IDS_PROP_FORM1;
//}}AFX_FORM_DATA_END
}
If your form was
created with "3 - Way RAD" option, then the constructor should look
like the following
CForm1::CForm1()
{
//{{AFX_FORM_DATA_START
m_rect = CRect(0, 0, 300, 300);
//}}AFX_FORM_DATA_END
}
Please make sure
to
refresh your active project using RadVC's "Refresh Project Info"
option after you make the change.
