Hi everyone,

I am attempting to find the size of the programs window. This is so I can recalculate the size of any objects held within it should the user re-size it.

I have searched both the forums and the help files in an attempt to get a solution to this, and even just bought the Enhancements expansion pack in the mistaken belief it would address this issue(it doesn't so I have just wasted £19.96 )

Any help would be greatly appreciated.

Sorted - I found the appropriate commands in IanM's superb Matrix1Util collection. This stuff is a real gold mine so for anyone who doesn't know about it, it is really worth checking it out here.

Just watch over screen width() and screen height()?

Where there is a will, there is a way.

...or Desktop Width() and Desktop Height(), if you meant the monitor's current display size...

As great as IanM's plugin is you don't need it for this.

True but I've yet to see the command that returns whether you're using a 17inch or 19inch screen...

The standard DBP commands do not provide an update after the window has been resized. i.e., if I have a 1024 x 768 window and then resize it, then "SCREEN WIDTH()" still returns 1024 x 768 irrespective of the real size whereas "GET WINDOW CLIENT WIDTH()" returns the new size correctly.

However, what neither command does is provide the information as the window is actually being updated, which is a bit of a pain as one only gets the new size once the user has completed the operation.

What would be really nice would be an option to stop DBP scaling things at all, as this is what I am really fighting against here.

Oh well, on with the battle.

I see your problem. If you reset the display size to match the window size you'll loose all your D3D data including loaded objects...

Just include this statement in you main loop...

Bam! You can resize the window and the object will all have the correct aspect ratio.

Nice, I'll add that into my editor...

Why do you add "0.0" to each value? Why not just write it like this?:

Thanks for all your help guys, I really appreciate it.

The 'set camera aspect' command is certainly one that I will remember for future, but unfortunately it is not really what I want in this case. I think that I had better clarify;

I am looking a coding a layout application. For this, I want to show a background representing (say) an actual sized piece of A4 or letter with a coloured surround. Should the user re-size the window, I want the A4 image to remain the same size (i.e. the image would be clipped or the surround made bigger)rather than scaled.

What I would hope to do is to get the window information as it is being resized, so that I can recalc the image info to prevent it being scaled in any way.

I had intended to use sprites as the actual objects that would be dragged onto the background.

Anyway, what I am finding is;

a) The window size information is not updated by DBPro until after the operation has been completed.

b) While the operation is in progress, the client area of the screen turns blue, with the redraw not happening until the operation is complete.

c) There appears no way to find what the dpi settings are for the screen. (this would be required so that I could map the background image to an actual physical size).

It may be that what I am attempting to do cannot be done using DBPro, but I will continue trying for the moment.

Integer division produces incorrect results. By adding the 0.0 to the width and height turns it into a float for correct divisions.

Doesn't look that way as when you move the window, focus shifts to windows rather than to the application. (Or something) 3D objects will display correctly, but 2d will not.

I didn't realise you had to be so explicit for returns from functions, I just assumed they came back as floats naturally, my bad.

Screen resolution is an integer, you can't have a screen set to 639.98 x 479.87 can you! lol
