visual basic 6.0 question

[Shannon]

I have a form with three text boxes and a command button. I have to write the instructions such that when the button is pressed the strings in txtBox1 and txtBox2 are concatenated and the results are displayed in txtOutput. Can you please show me how this is done?
Thank you

[da_silvy]

Private Sub Command1_Click()
Text3.Text = Text1 & Text2
End Sub

something like that?

[holy1]

code:


txtbox3 = txtbox1.text + txtbox2.text

if they r numbers then

txtbox3 = val(txtbox1.text) + val(txtbox2.text)

Don't concatenate strings with +, use & as Major da Silvy said. Then read my signature

[holy1]

whats the harm in using "+" ?

[seoptimizer2001]

For one, if you use Val() and +, it will add them not concatenate them.

i know that

didnt u read "IF THEY ARE NUMBERS THEN" USE VAL() else

dont use them

[seoptimizer2001]

Yes, I did read that part and that was why I said what I said, if you use Val() and Text1 = 3 and Text2 = 3 then you would have 6 not 33. So you would be ADDING not CONCATENATING, so you would never use the Val() function with concatenation!

Or like this if you happened to need a space between them

Private Sub Command1_Click() 

Text3.Text = Text1 & " " & Text2 

End Sub

JO

[Motoxpro]

i use

Private Sub Command1_Click() 
 
Text3.Text = Text1.text & " " & Text2.text
 
End Sub

like JO does i think that is the best way to do it and the easyist

[Motoxpro]

i use

Private Sub Command1_Click() 
 
Text3.Text = Text1.text & " " & Text2.text
 
End Sub

like JO does i think that is the best way to do it and the easyist

MSDN says:

When you use the + operator, you may not be able to determine whether addition or string concatenation will occur. Use the & operator for concatenation to eliminate ambiguity and provide self-documenting code.

It prevents the dreaded "evil type coercion"
