Basically i have a code for detecting user inputs of alphabets and numbers

C#

private void KeyPressForm1(object sender, KeyPressEventArgs e)
{
    Settings.Keypressed = e.KeyChar;
    label5.Text = "" + Settings.Keypressed;
}

private void KeyUpForm1(object sender, KeyEventArgs e)
{
    label5.Text = "";
}

However suppose in this application i have a button, this code does not work because the button gets automatically selected, it gains the blue shade.
I want to make is so when the button is pressed it works than in unselected

What I have tried:

Basically i have tried removing the button all together but i like using the look of a button

The "button gets automatically selected" when what ?

You need to clearly define the conditions under which you want to detect the KeyPress: all the time, for any control ? only for one, or some, controls ?

I can't understand the video. Try to answer the questions I asked you.

Exactly when do you want to get KeyPress Events ?

I would bet that disabling Control selection is not the real issue here.

Solution 4

Set the 'FormKeyPreview Property to 'false. Try this in the Form:

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
    // only to demonstrate you are getting all the characters
    // no matter what Control has the focus
    Console.WriteLine($"active control: {ActiveControl.Name} | key: {keyData}");
            

    // handle the characters here

    return base.ProcessCmdKey(ref msg, keyData);
}

Quote:
The ProcessCmdKey method first determines whether the control has a ContextMenu, and if so, enables the ContextMenu to process the command key. If the command key is not a menu shortcut and the control has a parent, the key is passed to the parent's ProcessCmdKey method. The net effect is that command keys are "bubbled" up the control hierarchy. In addition to the key the user pressed, the key data also indicates which, if any, modifier keys were pressed at the same time as the key. Modifier keys include the SHIFT, CTRL, and ALT keys.
