Can you tell me further details

I am using IGUIFileOpenDialog and it works well! But I found the IGUIFileOpenDialog seems can only find file in current disk driver. Hence how to change the working directory by code?

I found someones code like this:

env->addFileOpenDialog(L"Please select a model file to open ...

Just to named the icon to irrlicht.bmp and then the irr will be load!

Oh yes! Just to separate id from messagebox event!
But when the main program obtains lots of messageboxs to show information to user, it is a trouble for ours to manage the messagebox attribute!
And the implementation of the code is not the order of!

So any good idea?

I just want the next code will be runed until the messagebox was closed by user!
C++ knows the concept of classes and methods, so there's no need to 'stop' the execution of your code. Just call the code after your eventreceiver got the close event.

1. Create an EventReceiver which checks if the ...

addMeesageBox() has a "modal" parameter. Set it to true and the user can't interact with the gui except closing the message box.

But I found it isn`t block!

when the messagebox is showed! The next code also can run!
Now! I just want the next code will be runed until the messagebox was closed by ...

When you have a modal messgebox the user shouldn't be able to operate the mainwindow at the same time.
If that is what you meant...

Oh!

RunModal had the dialog which should be run modal as parameter and in the loop it checked if the dialog was still visible (although checking for messagebox-events might also ...

There is actually a way to get real blocking modal Messageboxes like you have them for example in MFC, but it's a little tricky.
Basically you have to code the same trick which MFC does use: You have to write your mainloop in such a way that it's called within a function which started the ...

But how can I send the event to main program!
I found the addmessagebox() doesn`t return the button value of OK/CANCEL!

I found the addMessageBox() funtion is not blocked;

Codes like:
...
env->addMessageBox(L"MessageBox Test",L"Hello
IRR",true,EMBF_OK|EMBF_CANCEL);

int i;
i = i + 1;

...

When I call the addMessageBox funtion, it exit soon!
Can I running the "i = i + 1" until the messagebox closed?
