Variable window placement with resources

Hi all,
I've centered my main window (with the DS_CENTER style) and want to dock a child window together with the main window at the right main windows border.
But using resources (an .rc file) for declaring the window dialog parameters I am unable to include variables for the resolution-dependant xy child window placement.
Is there a way to make this possible, even with resources or do I have to use another function than CreateDialog to make it work?

TIA for help,
Hawk

Since you're window is dynamically positioned,. a value cant be hardcoded for it into the resource file, but you can just use GetWindowRect to obtain the windows dimensions and then use SetWindowPos to set the dialog's x to the initial window's x + width.

You can hardcode it if you use it as a preprocessor constant!

eg,

Code:

#include "dialogsiz.h"  // contains #define RES_DIALOG_WIDTH 250
// ...

IDD_MAIN DIALOGEX DISCARDABLE 6, 18, RES_DIALOG_WIDTH, 346

// ...

for example

Preprocessor defines are the only kind of 'variables' I may use in resource files. But I can't hardcode the x-y-values themselves because they're not constant, they depend on the screen metrics. The x value of my childwindow would be resolution/2+mainwindow_width/2 (to the right of the main window), the easiest way would be @nthony's, it's also pretty simple because the child window doesn't show before I want it too, so I am going to reposition my child windows and then just show them (if there is really no way to do it with the resources)

Thanks for the answers!
