I have a modeless child dialog of another parent dialog.

when initializing the parent dialog, I set initial values for the child dialog controls; one of those controls ( more than one actually ) is a radio button group. That radio button group will enable/disable corresponding controls depending on which button is pressed.

Now, I want to initialize the radio with one value, and automatically enable/disabled corresponding controls ( like it would behave if the user click on one of the radio choice ).

I do something like :

//...
m_RadioValue = myRadioValue; // myRadioValue is the index to the radio button in the group.
UpdateData( FALSE );
//...

When doing the UpdateData, it will set the UI for the radio button, but is there a way to call the callback that would be called if the user clicked on one of the button; or do I have to do all this manually ? not a big work, but will need a bit of code re-organizing.

hope I was clear enough.

Thanks.

I would refrain from using UpdateData(), especially with radio buttons. Create a CButton control variable for each radio button. In the dialog's OnInitDialog() method, do something like:

if (1 == myRadioValue)
{
    m_button1.SetCheck(BST_CHECKED);
    OnButton1();
}
else if (2 == myRadioValue)
{
    m_button2.SetCheck(BST_CHECKED);
    OnButton2();
}
else if (3 == myRadioValue)
{
    m_button3.SetCheck(BST_CHECKED);
    OnButton3();
}

I will remove the UpdateData ... I already have CButton for each button.

Thanks, will look into that.

I think that my problem lies elsewhere, when I call my method to enable/disable controls, it does not work.

I do this in my OnInitDialog :

m_Radio1.SetCheck( BST_CHECKED );
m_Edit1.EnableWindow( FALSE );
m_Edit2.EnableWindow( FALSE );
m_Edit3.EnableWindow( FALSE );

but all of there are still enabled when the dialog appears. Confused | :confused:

'nyway ... In the grand scheme of things, it's only a minor, minor UI glitch.

Thanks David.

I'm certain I asked that same question a couple years ago ... Sigh | :sigh:

Do you have other staments where EnableWindow(TRUE) is called?

no, not that I can see, I put breakpoints everywhere ( running in debug mode ), and they never get called before I actually want them to be called.

I went this way, I disabled all my controls in the resource editor, and enabled them as needed ( instead of disabling them in the code ) ; my problem is when I initialized the dialog, not when using it.

Thanks.

Just to verify, temporarily change all EnableWindow(FALSE) calls to EnableWindow(TRUE). Even though a breakpoint is not being hit, this will at least eliminate the debugger as masking the problem.

Again, temporarily change all the controls to be enabled via the resource editor. Now your dialog should come up with all of the controls enabled. Yes? If so, start changing one statement at a time, or one control at a time in the resource editor, until the problem shows up.

Are you suspecting a resource ( ID related ) mixup ?

I will look at this tomorrow ... will launch a full rebuild when I leave tonight, to remove all possible conflicts.

Thanks.

No, but don't dismiss that either. I'm trying to rule out the possibility that a EnableWindow(FALSE) statement is actually being called even though the breakpoint in the debugger is indicating otherwise. I've seen it happen a few times.

I need help in trying to code a report using Crystal Reports in C++. I can not find any examples using this capabilities. I find some using VB and C# but not C++. I could use anybody's help. Either an example or direction.

Thanks

Are you trying to run the report, display the report, or programmatically modify the report (you use different things for each)? By the way, you'll want to use their COM objects in C++, which aren't hard to use, and the VB and C# examples somewhat translate. By the way, which version of Crystal are you using?

I will be doing all of the above. I am using the one that comes with .Net 2002 and or 2003. I have both. Currently I have finished the data collection phase and now I neeed to do the reporting phase against the data being collected.

In MSDN, under "Crystal Reports for Visual Studio .Net":

When you are creating a C++ project to host Crystal reports on the Web or Windows, you should choose the Managed C++ Application template.

Procedures that involve design view operations and automatic code generation to incorporate Crystal reports generally apply to Visual Basic and Visual C# projects only. You should use the Report Object Model, the Web Forms Viewer class description and the Windows Forms Viewer class description to incorporate Crystal reports in Managed C++ projects.

It looks like the only portion of Crystal Reports they distribute with .Net is the .Net version, not the ActiveX controls or COM interfaces. So, is your C++ app a managed app?
