Capture ENTER key while working with textbox

[phillipsbrian]

I have achieved a good amount of programme as my first VB programme. So far all the bugs are out but!
I have been trying to work with a TEXTBOX and am really confused.

my aim is to have the user type two numbers into a textbox, and then to operate on those numbers and store them into another textbox window.
I have tried various ways without sucess. ie. entering two numbers and hitting return, the programme then looks for the chr(13) and passes on to the next input, but the return key is not seen. If I enter a space instead of return and the programe looks fo a space, then that is detected. Can anyone please explain what is happening?
Thank you

Hello, phillipsbrian!

I think you mean adding two numbers and adding the result in a textbox. If this is the case:

Private Sub Total_Click()                        'total command button
    Dim Num_One As Integer
    Dim Num_Two As Integer
    Dim Total_Results_Num As Integer
 
    Num_One = Int(Text1.Text)
    Num_Two = Int(Text2.Text)
 
    Total_Results_Num = Num_One + Num_Two 
    Text3.Text = Total_Results_Num
 
End Sub   
 

(1) You have added two textboxes, namely, Text1.Text + Text2.Text and adding the results to Text3.Text

(2) You have also also dimensioned Num_One & Num_Two, lastly Total_Results_Num for integer place holders

If this is not what you hoped to achieve, please let us know.

In a bit!

Thanks dok,

but sorry that was not what I wanted.

I wish the user to enter two numbers( ex: 44) followed by a return, into textbox1, and be able to trap the return key.I will then have the two numbers in a string for further use!
In other words, once I have a return key entered I know the user has finished input and we can take the "textbox.text" into a string and leave the routine with the string carrying the double number.

Something like the old fashioned getkey argument, where one can accept keys one after the other into a string until a enter key or similar is entered and then drop the input and operate on the string!

Best regards, brian

Ok, I'm talking VB6 here - so if you're using a later version some or all of this may be useless to you.

Generally, you would probably do something like putting a command button on the form (hidden away where the user can't see it, if you like). Set the .Default property of the button to True, and it will be triggered when the user presses Enter. (I think there's nothing you can do to stop it beeping on Enter, but I could be wrong.)

Another alternative is to put code in the KeyPress or KeyDown event for the textbox, to watch what is happening. Or if you turn on the KeyPreview property of the form, it will get to see them first, before the textbox does.

(By the way, I've modified the title of the thread, in line with the site posting guidelines. This makes it more useful for anyone who later comes searching for similar information.)

Hi Brain,

May be I am very late and Hope you might have got the solution, but, if my this reply helps someone, i would be very happy.

If I got ur problem understood correctly,

in the Text_KeyPress() procedure, put this sentence if I am correct

If keyascii = vbkeyreturn then ...

Hope I reached this problem.

With Regards,
Mohan

In the KeyPress sub, the
"if keyascii = vbkeyreturn then" works just hunky and
dorey .... follow that with
keyascii = 0 to supress the beep .....
