Keyboard events handler for C# WinForms application

Question

Hi,

how can I do global keyboard event handler for C# winform application? I think it should be a separate class with some methods and events, but I do not know exactely how to do this. Global handler should provide funcionallity to catch key pressed (for handling shortcuts).

best regards

Answer 1

Just so you know, you should never loop through to build strings, they are immutable and this gets very costly. Use: StringBuilder sb = new StringBuilder(); foreach(Control co in r.Cells[2].Controls) { if (co.GetType() == typeof(Checkbox)) sb.Append((Checkbox)co).Checked.ToString()+"\n"; } string output = sb.ToString();

Answer 2

foreach(Control co in r.Cells[2].Controls) { if (co.GetType().Name.ToString() == "Checkbox") TextBox1.Text+= ((Checkbox)co).Checked.ToString()+"\n"; }

Always the same...you post a question then work it out!! the answer was to use the uniqueid of the control and then use findcontrol to return it. Also needed to cast the control etc. now it all works and heres the code foreach(Control co in r.Cells[2].Controls) { CheckBox cb=(CheckBox)this.FindControl(co.UniqueID); TextBox1.Text=TextBox1.Text+cb.Checked.ToString()+"\n"; }
