How to preload dialog fields


I am writing an mfc based visual c++ application (Visual Studio 2008) and I am having some
difficulties with configuring a modal dialog box.

The dialog box is intended to configure database access parameters - database name,
password etc.

Problem is that I can't figure out how to preload the fields on dialog box creation
ie I need to read some data from the registry, and populate the fields.

Any suggestion for this would be appreciated.  I've tried a number of methods including overloading OnInitialUpdate, but no success.

Hi chrisd-r,

best place to do this is in an overloaded 'OnInitDialog' (which you can easy add via ClassWizard by adding a message handler for WM_INIT_DIALOG message) somehow like this:

> BOOL CMyDlg::OnInitDialog()
> {
>  CDialog::OnInitDialog();
>  // load your values here and fill the controls
>  UpdateData( FALSE ); // This is needed if you use DDX-Data exchange using variables for controls
> }

Hope that helps,

Here you can find samples for some different ways to init the values of an edit control: http://functionx.com/visualc/controls/editbox.htm

Thanks for the help - It is now fixed.

Forgot to call UpdateData(FALSE);
