MessageBox in OnInitDialog

[fjlv2005]

Good day, I have on my OnInitDialog an initialization and if there the returncode of the initilization is error then I display Error using Messagebox. However After I press Ok button, I got an access violation. Is there a proper way to have MessageBox in OnInitDialog? Thanks.

don't do it like this. if you have an error, throw an exception that you will catch in the InitInstance() function. there, you can put the code of your messageBox.
