Catch Enter Key

[feurich]

[csharp]
private void cboImportset_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
// Catch the enter keypressed
if (e.KeyChar = Keys.Enter)
// {
// Check if ImportSet already exists if so select ImportSet.
// if ImportSet doesn' exists add it to ImportSet list.
MessageBox.Show(e.KeyChar.ToString());
// }
[/csharp]

Errors are:
- Cannot implicitly convert type 'char' to 'bool'
- Property or indexer 'System.Windows.Forms.KeyPressEventArgs.KeyChar'
cannot be assigned to -- it is read only
- Cannot implicitly convert type 'System.Windows.Forms.Keys' to 'char'

That shouldn't even compile. Your if statement is invalid. ( == )

 

[feurich]

Sorry for that

But even with the == inplace it doesn't compile.

error is:
Operator '==' cannot be applied to operands of type 'char' and 'System.Windows.Forms.Keys'

I know I have to convert the e.KeyChar. But how.
In VB.NET you have the Asc() function but what is that in C#????

 

[thenerd]

Try e.keycode instead of e.keychar.

 

[feurich]

No e.KeyCode

I don't have e.Keycode in my intellisence...
Also on a lot of website it says that there must be a e.KeyValue in the event arg.
But I don't see it.
Any info on that?

 

[feurich]

ok found it

This is it....

if (e.KeyChar == (char)13)

Man, converting from VB.NET to CSharp isn't that easy

 

[thenerd]

Are you sure? Try typing e.keycode anyway. I know I have it in vb.net.

 

[feurich]

Tried it

I tried it but when i compile the code it says:
'System.Windows.Forms.KeyPressEventArgs' does not contain a definition for 'keycode'

See my last post. That does the trick.

Thanks for the effort.

I am just guessing. . .

but does this work?

e.KeyChar.Equals(Keys.Enter)

 

[Joe Mamma]

actually it doesnt but this does.

bool isEqual = e.KeyChar == Convert.ToChar(Keys.Enter);

which I would prefer rather than the (char) cast of #13

 

[Joe Mamma]

also. . .
KeyCode is a member of KeyEventArgs but not KeyPressEventArgs.

FYI
order of events -
KeyDown (a KeyEventHandler)
KeyPress (a KeyPressEventHandler)
KeyUp (a KeyEventHandler)

 

[IngisKahn]

Why not e.KeyChar == '\r'

 

[Joe Mamma]

Why not e.KeyChar == '\r'

Only that I can never remember escape sequences.
