FOR loop exercise - Help appreciated.

By the way i might need help doing another exercise which is on nested loops. I need to display the sum of row and column numbers for 4 columns and 5 rows, and there has to be "+" sign at the top left hand corner.

I will most likely need help, but i will have a bash at it first.

Thanks.

Thanks for the advice michael, really appreciated.

By the way i just cannot get my head round this nested sum. Here is my attempt:

Dim rownumber As Integer
Dim colnumber As Integer


frmnestedsum.Show

For rownumber = 1 To 5
For colnumber = 1 To 4
result = rownumber + colnumber
frmnestedsum.Print rownumber & result
Next colnumber
Next rownumber


By the way, do you recommened that book? I have read the reviews on Amazon and they all look really good. Did you use that book for learning Visual Basic. I think i might order it then if you recommend it, as sometimes i have trouble on understanding some concepts.

Thanks alot.

Try this:


Dim rowNum As Integer
Dim colNum As Integer
Dim result As String

'print top line
result = "+ 1 2 3 4" & vbCrLf

For rowNum = 0 To 3

'add row header
result = result & (rowNum + 1).ToString & " "

For colNum = 0 To 3

'add results for each addition
result = result & ((colNum + 1) + (rowNum + 1)).ToString & " "


Next

'add row footer
result = result & vbCrLf


Next

TextBox1.Text = result

It might need changing if you want it to work in VB 6.

HTH

**** me, even I'm slightly confused by that
It's efficient, but no VB newbie is going to understand all of it...imagine if his teacher wants him to explain how a particular line of the program works (I certainly had this problem with my computing teacher) - he'd be pretty screwed, eh?

Anyway, a newbie-friendly version:
Dim colNum, rowNum, result as Integer

For rowNum = 0 to 4
For colNum = 0 to 4
result = rowNum + colNum
frmNestedSum.Print result;
Next
frmNestedSum.Print
NextThis code will give a printout that looks like this in VB6
No need to use things like the ToString command that you won't have come across yet, and it should be easy enough for you to follow and explain if you have the need to
The only things I will point out, just so you know:
Where it's printing result, the semicolon at the end of that line means that any input after it is added on the same line (I was expecting that I'd need to add a space, but this appears to happen automatically).
That's why there is another print command outside the for loop, which does absolutely nothing but move you onto the next line. If that print command was missing, the output would look like this:
