Get information about serval given keys is pressed?

[panyl]

I want to process something when keys.control and keys.left are pressed at the same time,so how do i know if them are pressed at the same time? Thanks!(C#)

Detect when the control key is pressed and released and store the status in a variable, so that when the left key gets pressed you can check if the control key is currently pressed.

Despite everything, the person most likely to be fooling you next is yourself.

Thanks for you reply! I have solve my question. code: //Onkeydown if(e.KeysData.tostring().contains("Control")&&(e.Keysdata.tostring().contains("Left")) { // do my work; } But i found a erratic thing: if i press keys.left or Right/up/down,it ignore me in function OnKeyDown,OnKeyUp,OnKeyPress; if i press keys.control and keys.left,it will process my work; if i press keys.shift and keys.left,it will ignore me in function OnKeyDown,but process in OnkeyUp; ..... i want to know when will those events occur?Could you help me?

Hi, you can get the instantaneous value of the modifier keys using Control.ModifierKeys so you don't have to track those keys yourself (which you can hardly do correct, say e.g. the CTRL key gets pushed down on one Control, then released above another Form). BTW: don't convert to string for a logical test; instead of if(e.KeysData.tostring().contains("Control"))... you can do: if ((e.KeysData & Keys.Control)==Keys.Control)... or if ((e.KeysData & Keys.Control)!=0)... :)
