MFC Bring up a dialog.

[guitarist809]

Hello,

I already have a basic MFC Application created (with the default dialog and the about box, and another one I made called IDC_DIALOG1) using the standard MFC library. My question is how do I make a dialog pop up?

is it like IDC_DIALOG1.PaintDialog() or something?

Thanks,

How you show the dialog depends on the type of dialog it is and how you are using it.

What type of dialog, modal or modeless?

Basic steps;
1. Create a class based on the dialog.
How you do this depends on the version of MSVC you are using.
Try double clicking on the dialog in the resource viewer.

2. Include the header file for the new dialog's class in the main dialog.

3. Create instance of dlg class (a variable)

4. Call DoModal()

//create a class CMyDlg from IDD_DIALOG1

//include the class in the parent dialog
#include "MyDlg.h"

//in the method you want the dialog to appear
//create the dialog class
CMyDlg       MyDlg;

//create modal, 
//does not return from the dialog until the dialog is closed
int             iReturn=0;
//catch the button the user clicked to close the dialog
iReturn = MyDlg.DoModal();


//now the IDD_DIALOG1 code will run,
//until the user finishes and closes the dialog


//what did the user do
if(iReturn == IDOK)//user clicked the OK button
{
//do stuff
{
else if (iReturn == IDCANCEL)//user canceled the dlg
{

Post if you need a modeless dlg, which runs at the same time as your app.

I honestly don't know the difference between a modeless dialog and a model dialog =\

i did the DoModal() and it automatically put two buttons (OK, CANCEL) and a text message (TODO: PUT YOUR CONTROLS HERE) even when the dialog was empty.

I'm assuming that's not supposed to happen...

It is important and you need to know the difference.

I could tell you.....but I won't.

Google it....

Sounds like you used a brand new dlg, not the one you made. New MFC dlgs are made with two buttons and a static (telling you to place controls).

So it is somewhat expected. Shows that you have it mostly correct.



Are you using the resource editor?

What version of MSVC are you using, v6 or 2003 or 2005? If you have 2002 then upgrade/patch to 2003.
