Ok guys... here's something heavy... Guess I won't receive any answer, but well, I'll try Try to make some new project with a full screen form, no border, in any res you want, and add a tray icon [http://www.vb-world.net/api/tip61.html] (with some API call) for it... when it starts (The form shows), it change your resolution automatically [http://www.andreavb.f2s.com/tip090004.html] (another API call...) with the project (ie: 800x600)... make some button that when you click on, it hide the form and change your res to your initial configuration (ie: 1024x768)... now check at the mouseon_event of the picturebox that your tray icon uses... the "Case WM_LBUTTONDBLCLK" will change your res back to 800x600 and show the form again.. but the form wont get any focus: you need to click on it before... why??? when you make some menu and your dbl click call it, instead of showing off the form, the form gets focus! Can someone experienced help me please?
