How to change the Title(Caption) of Modal Dialog Box?

mikert_2008

Hi, I have the dialog box. Which I am using as Modal dialog box with DoModal functionality. I need to change the Title(Caption) of dialog box before calling the domodal(). Since I am deciding the title of dialog box at run time I can't use the resource setting. One way I know to change the title of Modal Dialog Box is to use OnInitDialog() function of the class derived from the DialgBox and then call setwindowtext() function inside it. But I want to change the title/cation without using OnInitDialog as the project I am working doesn't have class derived from it. And doesn't look proper to genrate the class just for this purpose. Can anybody knows the other way of doing it?? Thanks in advance.. Mike.

define a public string member in your dialog class which get set between ctor and oninit and will do setwindowtext()in your OnInitDialog()

I assume from your comments that this is a Win32 dialog rather than MFC. If that is the case you can still trap the WM_INITDIALOG[^] message and change the title there.

It's time for a new signature.

I think that you may do it, using the CDialog::InitModalIndirect route (see [^]), but it would be "full of pain", because you have to create and fill properly the DLGTEMPLATE struct ([^] read carefully the "Remarks" section). :)

Nah, inheritance is not an option in Win32. :)

Hi, As I mentioned I am not having any Dialog class where I can use the OnInitDialog() function. I want to do it without using it. What I am trying for is the without using separate dialog class for it. Thanks Mike

Hi, I am aware of the InItDialog functionality. But I am not having Dialog derived for it. I am trying to avoid the creation of seperate class for this purpose. Is it possible to change the dialog header without using InItDialog?? Thanks:- Mike

Hi, It's for creating Modal dialog box indirectly. But I already have the dialog box. Thanks:- Mike

That's the only way, IMO. :)

Even though he mentions DoModal()?

So what object are you calling DoModal() from?

CDialog dlgAbout(IDD_ABOUTBOX); dlgAbout.DoModal();

Just an idea to research further. Before you instantiate the dialog, would it not be possible to modify the IDD_ABOUTBOX dialog resource to change the caption property? I don't know how to do that, but that is one thing I would investigate. :)

I *think* this is what InitModalIndirect() was suggested for. Like you, however, I've not personally tried it.

Other than looks, what reservations do you have to this approach? Read here for Paul's response to using a CDialog object directly.

I had a quick scan through the answers below and you didn't seem that enamoured of any of them as you weren't using/couldn't use MFC. Having said that you've already answered your own question...

If you look at the MFC documentation or read the source code you'll see that CDialog::OnInitDialog is called in response to a WM_INITDIALOG message being sent to the dialog box. All you have to do in your code is handle WM_INITDIALOG and call SetWindowText at that point. Cheers, Ash
