[net2knot]

could nebody help me out of this problem.
i want to send numeric enter key to a dos application. i tried sendkeys but it doesn't trace out the dos application.
i have designed new module but it also doesn't differentiate between standard enter key and numpad enter key.

Sorry to see you're not getting any response to this.

I'm afraid I don't know the answer, either. VB doesn't seem to differentiate between the two Enter keys, same with Shift, or Control or Alt. I knew KeyPress events wouldn't care which Enter was pressed, but was a bit surprised to find that KeyDown also doesn't care.

All I can think of is to try to track down a Windows API function to send a message indicating that a particular key was pressed. I did a quick Google search on "windows api send key" and came up with a few entries that sounded interesting. Try it yourself, or see whether these first couple are any help...

• SendKeys using the API
• Send Keystrokes to Applications Using Windows' API SendInput

P.S. I'm using VB6, what version do you have?

One very important thing to remember, with SendKeys and probably also with Windows API functions. If you send a keyboard event, it will generally go to whatever currently has the focus. So you will generally need to set the focus to the appropriate window before simulating a keypress.

In other words, generally you don't send a key to anyone in particular. You are simply telling Window "the user pressed this key". So it will handle it however it would normally.

thanks killer42.

All I know is that I tried many years ago to get some text to or from a DOS applciation and found that they are a completely different story to a regular Windows one. I don't think I was ever successful, but I also didn't try very hard - I was just curious.

I've just tried a Google search for "vb interact with dos". Here are the first few entries which sounded as though they may be of some use...

• Reading text output of a DOS box
• Managing Keyboard State in DOS, VB6, and VB .NET: A Brief History
• VB5.0 SendKey Function To A Dos Program
• Create true console-subsystem applications in Visual Basic that interact with the command-prompt from which they were launched

Note, I think the last one is an overview of a commercial product.
