Loops

kegan5

is it possible to use a + command without using a loop?

Im looking for code that adds 1 to a number when someone clicks on the confirm button..however the only way I can get it to work is by using a do while loop and although this works it has to have a condition so I cant keep the loop running for the whole program it just keeps going around the loop 10 times because of the condition?
Any ideas
Thanks

c++ i assume

int loop_condition = 0

while(loop_condition == 0)
{
  blah blah blah....
}

the infinite loop

em, language and what you are trying to do would be nice....

Sounds like you just want to add 1 to a variable every time someone clicks on a button, if thats the case what you want is to write a function to do it, however I could be wrong because you confused me with talk of loops, and whiles.

Sorry its VB but would that work in Vb...? I'll try it thanks

if you are just incrementing a variable by 1 every time the command button is clicked, then yes all you need to do is have a sub for the button clicked event to do it.

kegan5

Private Sub cmdConfirm_Click()
Dim intX As Integer
intX = 0

MsgBox "The number if people enrolled on this course is " & intX
intX 1



End Sub


Thats the code I was using, as you can see theres no + and it just automatically deletes it when I put it in and it says :
"Expected Sub, Function " ?

'Make this global. If it is local it gets reset every time you enter the Sub
Dim intX As Integer

Private Sub Form_Load()
'initialise in the forms load event
intX=0
End Sub

Private Sub cmdConfirm_Click()
'Add 1 to intX, and print message
intX = intX + 1
MsgBox "The number if people enrolled on this course is " & intX

End Sub

Typedef

Umm why don't you just make your integer static

Baz_

umm why not indeed...

Except, as Type pointed out, the ones defined as static.

Cause thats exactly what static variables are for...
