I also do not want to program a mouse click because it is cumbersome and because even in full screen one has to factor in the zoom factor.
I am using SHDocVw.InternetExplorer
The Webbrowser will also do.

Question: I want to control cmd.exe from winforms. I DO NOT mean every command in a single process, with startupinfo, and then stop. I mean for example start the (My) SQL or GDB command prompt, send command, receive answer, send next command, receive next answer, stop SQL command prompt exit process. Basically I want to write a GUI on top of any console application.

I was working with TabControl on a form.I wish to restrict the selection of the tabs on the form...For example, The user will start with the 0 index Tab selected by default.As he selects an option from that tab pane n confirms his selection, The next tab gets selected.

Which I do not want. I simply want the tabs to be activate in a flow...

View 1 RepliesWith many of the programs that I use, I have noticed that the file dialog boxes automatically enter a new folder (if I create a folder thru the dialog box). But my OpenFileDialog boxes don't do that in my programs.When I open the OpenFileDialog and press the New Folder button, the box stays in the current directory and I am forced to click into the new folder. I have researched the OpernFileDialog and I don't understand how to change this behavior. I want to eliminate this extra click to enter the new folder.

View 6 RepliesI have no difficulty creating and operating a regular notifyicon... But I have an issue - more with method than with the code itself...
Here is what I am doing - I have a notifyicon that changes colour based on the status of a service - this is not an issue...
However, I want the icon to be able to appear via a startup program itself instead of from inside the service (obviously if the service is STOPPED the icon will not be visible making it difficult to start)
The service also changes the icon colour when it is performing a specific timed task (the purpose of the service) - I may also want to force the service to perform the task from yet another application outside the preset interval....but that is a seperate issue at this time...
the best way to have a notifyicon that can control a service(easy) while being able to be controlled BY the same service.(the issue)
