on your OnClose and on OnOK functions, make sure you add

CDialog::OnClose() or CDialog::OnOK() after anything you do.
If you override them and leave them empty of course they will do nothing Smile | :)

Yes. Just I removed the OnCancel derivation. I feel my program as I expected. May be some other solutions too to handle the OnOk and OnCancel also. I think some PreTranslateMessage function is useful. I dont know exactly about this. If any let me know than I am very thankful to him.

Application's Icon

Hi,

When I used Visual Studio 6, life was easy, I would edit the main application icon and when I created a desktop shortcut for it, there is was. The same for the 16X16 icon, when I created it, you could see it in the windows explorer.

However, when working with Visual studio .NET 2003, my Application's Icon will not change and stays the default MFC icon.

Any help will be great.

in fact, a .ico file contains several icons, varying from the size and/or the number of colors.

when you edit an icon with the icon editor within Visual Studio, you should verify that all the devices (that's how they're called) are like you want...
(search the menus for that ; i don't remember exactly where).

How to handle events fired from ActiveX control

7-Dec-05 8:19

Well, you set it from the Image menu, I just found out.
Thanks.

Hello,

I don't know why this is proving difficult. It is obviously a very common task. I have an SDI application that is hosting an ActiveX control. The ActiveX control has some events that it fires. I want to handle these events in the host application. I cannot figure out how to hook it up.

The ActiveX control is not added at design time. It is dynamically created.

Thoughts?

Thanks!

You still have to implement the event sink which means that you need to know how the sink interface is defined.
The easiest way is to add the control to the project at design time and use ClassWizard to generate the event sink.

When you 'hook it up' you have to use IConnectionPointContainer and IConnectionPoint interfaces and in the end call IConnectionPoint::Advise and provide an interface pointer to the sink.

It's supposed to be hard, otherwise anybody could do it!

Thanks. I'll look into this method.

still... this is extremely common right? It seems like there should be an easier way. Something through class wizard..?

Change icon in caption of CDialog window.

7-Dec-05 7:33

Look at the Windows MFC site for the description of the SetWindowPos() function, you can understand it from there, I am sure.

How do you change the little icon picture in the title bar of a CDialog window?

Re: Change icon in caption of CDialog window.

7-Dec-05 7:09

you have to change the IDR_MAINFRAME resource with the new icon (still in OnInitDialog())...

Change caption on CDialog.

How do you dynamically change the caption title in .NET for a CDialog window?

Heather Heiman

toxcct7-Dec-05 5:56

CDialog is not a .NET class, but a MFC one.
i so consider you're using MFC.

you simply have to do this :

this->SetWindowText("new caption");

in a function of your dialog class...

I tried that line of code, but it doesn't seem to do anything. I even called UpdateData to see if that would work. I'm calling SetWindowText in OnInitDialog. Is there another place I should call it?

Heather

toxcct7-Dec-05 6:28

7-Dec-05 6:28

there's no need to call UpdateData() if you use pointer (here, this).

you might be doing something wrong because it works fine for me (according you call it into OnInitDialog(), not into the dialog constructor)...
