Hi ScottA,

Did you try it with 2 sub dialogs after each other?
So opening one, close it process it and then open the same one again.
For me that is the issue.

I tried this->Close(), but that did not help.

PS I am using R16

I'm using the code I posted to test it. Which has one main dialog and one sub dialog(another GeDialog).
I added a close button to the sub dialog.
When I close the sub dialog with it's close button. And re-open it again using the main dialog. The sub dialog is not empty. It's all still there and working as expected.

So, in the main dialog I open the sub dialog, do some processing and open the sub dialog once again. Both times in the command of the main dialog.

Hope this explains.

I don't understand why you are opening the same sub dialog when it's already open?
Or do you mean that you close the sub dialog, and then re-open it a second time?

Either way.
If I open the sub dialog. And then try to open it again(even though it's already open). It still works as expected for me. The sub dialog never goes blank(shows no gizmos).

Here is my plugin that you can test out.
No matter which buttons I use on either dialog. The sub dialog always works and never goes blank.
It should work in R16: http://www2.zippyshare.com/v/XVulPng9/file.html

(New input from the user).
Thanks for the plugin.

Hi ScottA,

Here your original file with my additions to show the issue.
To make it working in R16:
- changed LONG to Int32
- changed gNew MyDialog_CMD to NewObjClear(MyDialog_CMD)
- added #include "c4d.h" in .h file

- changed the sub dialog mode from DLG_TYPE_ASYNC to DLG_TYPE_MODAL
- add a second call to open the sub dialog for a second time:

        case MY_BUTTON1:
            subDlg.Open(DLG_TYPE_ASYNC, PLUGIN_ID,-1,-1, 200,100, SUBDLG_ID);
            subDlg.Open(DLG_TYPE_ASYNC, PLUGIN_ID,-1,-1, 200,100, SUBDLG_ID);
            break;

So far it is still working.
After closing the first (modal) sub dialog, the second one is displayed correctly.

Now I want to close the Modal sub dialog, when the user entered his input.
So I add a Close() in the command of the sub dialog

       case MY_CKBOX:            
            GePrint("Enabled");
            Close();
            break;

Now, after  the user entered his input, the first modal sub dialog is closed, but the second one opens up empty!

Here the full code.

The .h file
#define ID_DIALOG 123456789
  
#include "c4d.h"

The above code example is a bit silly, but the idea is that the user should enter his data using the same sub dialog twice.

Hope you can help me.
If not, the user has to close the sub dialog by closing its window, before he can continue.
In Python it is working!

You're opening two sub dialogs that have the same ID# using MY_BUTTON1. That's a big no, no.
If you want to open 2 sub dialogs. You will need to create a class for each one of them, and give each one a unique ID# to avoid any clashing errors.
I don't know why it works in Python. But it really shouldn't.

Can you post your R16 plugin with the source code anywhere?
I think it will be simpler to debug things having your actual plugin in hand.

Here a link to a zip file with the R16 .h and .cpp file.
It is the same code as posted earlier.

Note: I develop in R16, so it is supported under R16, R17 and R18.

OK. I think I get it.
What you are doing seems a bit strange to me. But you must have your reasons for wanting to do it.

Your sub dialog is a class. And just like any class. The way you use them is to make instances of the class. Then use those instances throughout your code.
So if you want to open the same sub dialog twice. You need to create two instances of it in your master dialog.
Right now you only have one instance and you're trying to use it twice, which is illegal.

In your master dialog's class define a new sub dialog class instance

class MyDialog : public GeDialog  
{  
  MySubDialog subDlg;  
  MySubDialog subDlg2;  //<---Add this to your code  
  INSTANCEOF(MyDialog, GeDialog);  
  
//...the rest of the class code

Then open your new sub dialog instance

Bool MyDialog::Command(LONG id, const BaseContainer &msg)  
{  
  switch (id)  
  {  
  case MY_BUTTON1:  
      subDlg.Open(DLG_TYPE_MODAL, PLUGIN_ID, -1, -1, 200, 100, SUBDLG_ID);  
      subDlg2.Open(DLG_TYPE_MODAL, PLUGIN_ID, -1, -1, 200, 100, SUBDLG_ID);//<---Like this  
      break;  
  
  case MY_BUTTON2:  
      subDlg.SetBool(MY_CKBOX, TRUE);  
      break;  
  }  
  return TRUE;  
}

That should prevent the second dialog from becoming empty when the first one is closed.
*But be warned. I don't think this is a good idea. I don't think these dialogs are meant to be used this way. I don't think they were designed to be created with multiple instances. The support guys can guide you better on that. It just seems wrong to me.
IMO. The better way to do this is to create another sub dialog class with it's own ID#. Then open them both the same way in your button code.

Ok, I like your solution and I agree that the issue might be as you state:
"Right now you only have one instance and you're trying to use it twice, which is illegal."

Until the support guys come with another solution, I will do as you suggest. Thanks.

Note: your solution works!

To explain my approach.
I have a plugin in which the user has to input an address and based on that input another address.
So sometimes one address and sometimes two addresses.
For both addresses I am using the sub dialog (seems logical to me).

- show sub dialog
- user enters address
- store address.city in firstAddress
- close sub dialog

- if firstAddress.city = Amsterdam
   - show sub dialog (again)
   - user enters second address
   - store address.city in secondtAddress
   - close sub dialog
