Call GUI(message box) from Dll

[Dilshad]

Hi,
I have a dll in which I need to pop up a Message box.
I do not have any QApplication as a parent. So I keep getting an error that I need to have a base GUI.
Is the base GUI really necessary?
Do I need to make an .exe file and then call the Message box from the dll?

Your help is much appreciated.
Thank you.

Is the base GUI really necessary?
Yes, if you want to have your DLL have a GUI - a message box is a GUI.
But the question is, do you really want your DLL to show a message box, or rather have an application which runs a gui, and links to your DLL.
When the application makes a call to the DLL when the call returns to the application you can have it return with a status, and based on that status show a message box from your application.
This will free your DLL from any dependency on GUI libs.
