Nor does anything like Keys.OEMPeriod for the period(del) key. I've also tried calling the enter key in a KeyPress event etc. But to no avail. Any ideas? I'm trying to mimic Windows calc.exe for a school project and thought I'd try throwing in a few extras such as numeric keypad functionality.

View 2 RepliesHow do I bind a keyboard key to an event? Everything I have found so far is related to using the keyboard for shortcuts to buttons on the form. I guess you could say I want to do the opposite.
For example: This is just basic code I did while learning how to use the xBox controller with my windows forms.
If currentState.Buttons.LeftShoulder = ButtonState.Pressed Then
tbLB.Text = " Pressed"
Else
tbLB.Text = " Released"
End If
Instead of changing the text in my textbox I want to have the left shoulder button or maybe my Dpad act as the "Tab" (let me worry about the controller I've got that handled, as not not confuse anyone) key on the keyboard in order to navigate through my form by tabbing upward or downward through a menu. Then maybe use the "A" button on the controller as the "Enter" key.
Where in: Replacing "tbLB.Text = " Pressed"" with code that would press virtually press the "TAB" key.
Of course using the xBox controller is dealing with XNA, but at this point I have figured out some basics of using the controller with my forms, just need to know how to mimic the keyboard keys.
What I'm trying to do is get the form to catch any key on the keyboard that has been pressed so it will reset a timer?

View 5 RepliesI am making an Auto Typer and it was going all good until I came apon a mysterious problem. When sending the space key or enter key with "Send Keys. SendWait" they come up with their numerical equivalent, 32 and 13.For example, a user types "test" into the textbox, and clicks "{Text} {Space} {Text}" in the options menu. The user clicks start and the output is "Text32Text32Text".Is there any way to just send the keys and make them appear as if you typed them on a keyboard?

I have made many web browsers that just navigate to a web page, I don't have any buttons or any thing like that as it is controlled via other software using shortcut keys etc.I have created a button in my other software that sends the keys strokes "Control" and "H" I can get this to navigate to a webpage by manually typing i the same page that it navigates to when the form loads, but this mean I have to type the address in twice for each browser I make.
