I'm not sure what you're trying to do. Do you want to enable/disable controls in the GeDialog? If so, just use the Enable(LONG id, Bool TRUE/FALSE) function. Much easier than sending a message, even if that's possible.

Hi spedler, thanks for your reply.

Unfortunatly, is not so simple. As described here:

https://developers.maxon.net/forum/topic/5664/5700_manipulate-extended-gedialog-from-ext-methods

I'm interested to call the "Enable" method on GeDialog from Threading context. This is not allowed. So, I have to to try with SendMessage sdk routine to achieve my goal but I have the described problem.

Many thanks for any ideas.

Bye

I don't think SendMessage will help in your case.

What you probably can do is to send a custom message through SpecialEventAdd() from your thread. Then this message can be received in your dialog's overridden CoreMessage method.

There is a small example in the docs for SpecialEventAdd().

Hi Matthias, thanks for your constants replies. I will try the SpecialEvent...I've already seen this method but I don't remember if I've already tested this solution. Tonight I try...this "problem" made me crazy...thanks again, I'll know if it works...

bye

Definitively thanks, using SpecialEvent we can manipulate now the gedialog using threading context. Bye.

And it will stay as long as you're calling the Windows-specific method (which you can't use in the context of Cinema's event system) instead of the GeDialog method...

Did I understand you right ? You want to to something in the dialog from another thread ?
I don't know about C++, but maybe this helps you:

When you want to send the message, don't send the message itself, instead create a variable the defines wether the message should be sent or not. Just some Pseudocode to clarify what I mean:

  
//Pseudocode, don't copy   
class MyDialog extends GeDialog {   
    boolean sendEvent = FALSE;   
  
    void Set_SendMessageOnNextUpdate() {   
        sendEvent = TRUE;   
    }   
    void Do_SendMessage() {   
        SendMessage();   
        sendEvent = FALSE;   
    }   
    boolean CoreMessage(id,msg) {   
        if (sendEvent) {   
            Do_SendMessage();   
        }   
        return TRUE;   
    }   
}   
  
class MyThread extends Thread {   
    void doMyStuff(GeDialog *dlg) {   
        dlg.Set_SendMessageOnNextUpdate();   
    }   
}

I'm not sure if this will really work as you wish, but maybe it helps you

Cheers,
Niklas

You do. The compiler's error message proofs it.

Bho....If I do, I don't know where I do...I've removed all "trash" includes, I've only:

#include "c4d_baseplugin.h"

I don't use any windows dependent method, the Thread is C4D Sdk based, but the message is:

error C2039: 'SendMessageA' : is not a member of 'C4DScenePlugin'

Now the prototype viewed with vs intellicode is correct but the error on define still stay...
