I've got a dialog box and I use picturebox to put bmp background picture to fill the whole dialog box. After that, I draw some textbox and button in the dialog box. My intention is to have the buttons and textbox infront of the picturebox. But what happen instead is the picturebox is always infront.. I've even tried to use "Ctrl+D" to try to change the tab order but it doesn't seem to work..
Can somebody advice me pls..

Make sure you set the tab order of the objects in the order they should appear on the screen. If you use the IDE's resource editor to create the dialog box and its objects then its pretty easy to change the tab order.You might have to experiment a little with the tab orders to get them right.
