Thread: Refreshing a seperate Dialog

Hello everyone,

I'm writing an MFC application and I need help with the GUI. So basically, I have some values that are stored as defaults to the registry and whenever the program is run/"Reset Defaults" button is clicked, all values revert to their defaults. I have been able to do this successfully for the dialog that the Reset Defaults button is in.

However, there are values in another dialog that I also want refreshed when I click the button. I have been able to store the default values in the registry and even retrieve them when the program run and when the Reset Defaults button is clicked using static variables. Unfortunately, I have only been able to reflect any changes to the dialog upon runtime in the dialog itself, but not when Reset Defaults is hit.

Is there some way that I can refresh the other dialog from the dialog that Reset Defaults is in so the different values are represented? Is there a better way to do this that I'm not seeing? Thanks.

Just set the variables in your dialog that represent certain controls data to whatever you want through the dialog's object. You will usually also have to at some point call some DDX routine if the dialog is already showing. Otherwise DDX will be called if you set the variables before you display the dialog.

If I understand you correctly, wouldn't that only work if the data and the controls are in the same dialog?

I'm not sure we're on the same wavelength here, but I've isolated the problem a bit more. Basically, I have a group of tabs (File, Options, OS_Attitude, and two that aren't important) such that the Tabs dialog calls and creates OS_Attitude. Under Options, I have some settings regarding logs and modes. Long story short, is there a way to have OS_Attitude call functions that are in the Tabs file?

Pass OS_Attitude a pointer to the Tabs dialog. Then it can call that objects methods. The point that I was trying to make is that you don't have to ask can I do this in MFC, but can I do that in c++.

You're telling me that you have 2 objects and want them to interact, so just get some handle between the two and access the objects interface.
