hey sorry but i did'nt know that xml example was'nt going to show up!:^) the html parser took it off.So i modified the above message. :-D

You can use the Process[^] class to do this. Dave Kreskowiak Microsoft MVP - Visual Basic

szevy_suez wrote: Actually, I just want my application to know when the other application has loaded As far as the application being loaded is concerned, it's when the next statement after whatever your using to load the other app executes. But that's NOT when the other app finishes initializing and doing its own startup stuff. There's no way to tell when that's done. The only thing you can do is write a routine to look for the title of a window in that application every so often. A ProgressBar isn't going to help you at all... szevy_suez wrote: then I can proceed with Appactive and sendkeys methods Good luck! Using SendKeys is not the most reliable way to controlanother application. The best method is if the application exposes a COM object model. Dave Kreskowiak Microsoft MVP - Visual Basic

Kind of. I know where you're going with this ... SendKeys. You can change the active application using VB6's AppActive function. All you need to do is give it the window title that it needs to find. The problem is, you can guarantee it's going to stay there between the time you call AppActivate and SendKeys get's done sending its information. Once your done, to get the focus back to your own app, all you do is call SetFocus on the control on your form that you want the focus sent to. Focus can change at any time, even while you, or SendKeys, is typing in a control. It's maddening when a background service just insists on popping up a warning dialog, or someone has a IM window open, like Yahoo Messenger, and a message comes in, stealing the focus from yours or any other application!

API stands for Application Programming Interface. It's a set of classes/functions that your code can call to interact with with application, operating system, or hardware you want. For example, Microsoft Word exposes a COM type library that outside applications can use to manipulate Word documents. You'll have to contact the manufacturer of the application your using to see if they supply an SDK (Software Development Kit) or API library to do what you want. szevy_suez wrote: The program I wish to access is a software built under GNOME desktop environment If you're talking about a Linux environment, then you're pretty much on your own. CP is dedicated to Microsoft's environments and developer tools, but does have people that support other environments, but there are no discussion boards dedicated to them. Does this help your cause?? No, it doesn't have any bearing on your problem at all. You still face the exact same problems. Dave Kreskowiak Microsoft MVP - Visual Basic

No, it isn't. You can't make another application be a child window, or control, of your app. Dave Kreskowiak Microsoft MVP - Visual Basic
