Arrays

Take a look in my first image named a.jpg ... there is my question ....




And This is my second question realting in my second image named b.jpg

what statement should i use to determine if a number is ( - ) negative go to the next cotrol array ... i mean ... like in my image b.jpg .... as you can see there is a numbers appear in my control array ... what statement should i use finding a positive number ... like this ... uhm ... the program must test if number of txtA(0) = ( - ) negative go to the next array which is txtA(1) if txtA(1) = still a ( - ) negative number go to next array which is txtA(2) if txtA(2) is not a negative number stop ... sorry in my english ... thank you in advance

txtA(0) = -1
txtA(1) = -1
txtA(2) = 2

Try

VB Code:

Dim pos As Long
 
pos = LBound(txtA)
'Do Until (Val(txtA(pos)) >= 0 Or pos > Ubound(txtA))  
'my bad an error can occur since Val(txtA(pos)) can't be tested when pos > Ubound(txtA)
 
Do Until pos > UBound(txtA)  'updated
  If Val(txtA(pos)) >= 0 Then Exit Do
  pos = pos + 1
Loop
 
If pos <= Ubound(txtA) Then Msgbox "stopped at txtA(" & pos & ") "

BTW, where are the images?

Help me please

Ahhh I see its a control array. To add

VB Code:

Dim cnt As Integer
Dim Sum As Double
 
Sum = 0
For cnt = txtA.LBound To txtA.UBound
   Sum = Sum + Val(txtA(cnt).Text)
Next
Text1.Text = Sum

Code in previous post for your 2nd question needs to be updated... it had assumed a string array but your using a control array. I'll leave the research on that (compare with recent code) to you.

Pretty avatar :D

In my second question is this right ?

Dim pos As Long
Dim arr(4) As Integer
Dim i As Integer

pos = LBound(arr)
'Do Until (Val(txtA(pos)) >= 0 Or pos > Ubound(txtA))
'my bad an error can occur since Val(txtA(pos)) can't be tested when pos > Ubound(txtA)

Do Until pos > UBound(arr) 'updated
If Val(txtA(pos)) >= 0 Then Exit Do
pos = pos + 1
Loop

If pos <= UBound(arr) Then
Text1.Text = Val(txtA(i).Text) + Val(txtA(i).Text)
End If

You don't need arr() since your using txtA control array as list source.

pos = txtA.LBound

Ubound(txtA) should be txtA.UBound

The last statement (Text1.Text = ... ) is confusing cause you never mentioned you needed a sum, you said you only needed to determine which control array textbox has a positive number.
