is there anyway through a dll call or something to get the state of the exit button in windowed mode?

so if something isn't saved you can say its not and ask to save before closing.

Or perhaps,
Use a message box instead and get the return value of the button:



Enjoy your day.

Well this one loads a DLL


The user32=1 is just so it's easy to keep track of the dll and what number it is assigned. So dll 1 is the user32 - I can see that just by looking at the variable name. If I had 100s of dlls, I wouldn't know what dll 1 was from dll 95, so I make the variable reflective of the actual dll name.

This command from inside the Function messagebox

is thactual call to the Windows messagebox function. The hwnd identifies the DBC window, the lptext$ is a string that contains the message we want displayed, lpcaption$ is the title that will show on the message box, and utype is the type of buttons to display on the message box.



I send the parameters to my function. bt has a value that means add a yes and a no button to the message box. I had to look this value up. Once the values are sent to the parameters, I call the dll function and it makes the message box. When a button is clicked, a numeric value is returned to the result variable.

That's how it works. Make any sense?

Enjoy your day.

Enjoy your day.

You'd want to retrieve the WM_CLOSE command. Once you get this command, you'd know to start your cleanup - confirm closing down the application, saving unsaved data etc. But the only way I can think of getting it is by subclassing the window. Maybe try GetMessage or PeekMessage.

Enjoy your day.

@latch

Edit:

ok i found peek and get message. but how do i know if the window is in the "threads message queue" or how do i add it.

and am i supposed to pass values into the function from the memblock(pointer to msg structure) or is it just to receive stuff?

@Caleb
What about using
SET WINDOW LAYOUT 0,0,0

and drawing your own title bar? That way you can use your own buttons and have your app respond how you want while still maintaining windowed mode. In fact, that would make using popup menus more practical than a Windows fixed menu bar - because you wouldn't be able to draw your own titlebar if you included a standard menu.

Enjoy your day.

When you click the exit or X button in windowed mode, it does the same as pressing escape. So at the start of your program use disable escapekey.

Then, further on, check if the user wants to exit with if escapekey()=1.

Is that what you wanted?
