Dialog Box question

Pett

Hi I want to bring up a dialog box when a button is clicked.I'm having problems getting the dialog box to appear when I click on the file. My code is: void CMainFrame::OnSFile() { m_chatterChooser.DoModal(); } And I've declared in the header: CDialog m_chatterChooser; Is this correct? :~ Thank you.

Gero Gerber

Did you create a dialog ressource and derived a new CDialog class based on this ressource? Gero

Pett

I created the resource, but no.. didn't derive a new CDialog class. I thought I didn't have to.:~ I will try that. Thank you!

Gero Gerber

Use class-wizard to generate the derived class from CDialog. Remember to select the right dialog ressource id when generating the derived class. Gero

Pett

ok, I've done that, but still nothing happens when I click on the button. What am I not doing?:confused:

Gero Gerber

Did you use class wizard? Did you chose the right dialog ressource id in class wizard? Which type is m_chatterChooser now? Gero

Pett

I have it as CDialog. I chose the resource ID for the dialog that I just built. (Chatter chooser). What do I have to change the type to? I put CCHooser which is the name of the class.. and I got errors. Please bear with me, I'm new to this. Thank you so much

Gero Gerber

m_chatterChooser must be of type CChooser

Gero Gerber

If your derived class is named CCHooser you have to include CCHooser.h in the source file where you have declared m_chatterChooser. #include "CCHooser.h" Gero

Pett

I have six errors!:confused: I have in my mainframe.cpp #include "CHOOSER.h" #include "CHOOSER.cpp" and void CMainFrame::OnSFile() { // attempting to open a small dialog box to choose a chatter to send file to: m_chatterChooser.DoModal();} In my mainframe.h: CCHOOSER m_chatterChooser; Also, the name of the class is CCHOOSER, but the fileview has chooser.cpp and chooser.h I know this is a simple thing.. why I am having so much trouble? :confused:

Gero Gerber

You must not include this line! #include "CHOOSER.cpp" Gero

Pett

If this wasn't me, ikt would almost be funny! Now I have 5 errors!

Gero Gerber

Just send me your project (gerogerber@gmx.de), or tell me which errors you get. Gero

Gero Gerber

Maybe a misspelling - try CChooser instead CCHOOSER. C++ is case sensitive. Gero

Pett

That didn't work, same 5 errors. I know C++ is case sensitive, that's why I put it in all caps. The class is in all caps. I'm going to delete the class and start again.. and give it a name that doesn't start with C! Is that a good idea? Thank you so much for your help!:rose::rose:

Gero Gerber

If you want send me the code. Gero

Pett

The whole project (actually it is two.. client and server) is large. Shall I send just the relevant code pasted in a document?

In the mainfrm.h mentioned write a line #include "chooser.h" (next to the other #include lines). Use the name of the FILE where CChooser is declared, not the name of the class itself.

You can not call a methos from an non-existing object. Hope this helped. If you post your errors, it is much easier to help you. Don't give up. You WILL make it. I know how intimidating I was in the beginning when the compiler spat out hundreds of errors, just for one missing comma.

Thank you so much.:rose: What you suggested worked! Pett.
