"Constant Expression" error, um help

Hi, I keep getting:

"Constant expression required"

when I run my code, and it highlights this:

Code:

---

  Dim myPic(intPicCount) As PictureBox

---

myPic is a Picturebox, and is;

Code:

---

Dim myPic() As PictureBox

---

so why isn't it working?

VB Code:

Dim myPic() As PictureBox         '<-Keep This, and then do the Following when you want to incriment its dimensions
ReDim Preserve myPic(intPicCount)   '<- use preserve if you have elements in myPic already, and you don't want to lose them. Otherwise its optional.

thanks, other question though;

how do I say if strMytext = Lowercase then

it wont let me do this either:

Code:

---

    ReDim myPic(intPicCount) As PictureBox
    myPic(intPicCount).AutoSize = True
        myPic(intPicCount).Picture = LoadPicture(App.Path & "\" & strName & "\" & strTempItem & ".gif")

---

why not?

it gives error "Object variable not set"

You didn't do it right.
If you've already :

VB Code:

Dim myPic() As PictureBox

{hopefully in the gen declarations area}

then its already dimmed as a PictureBox.
Now, if intPicCount is a number, then do this:

VB Code:

ReDim myPic(intPicCount)

NOT ReDim myPic(intPicCount) As PictureBox

its already a PictureBox. Don't repeat yourself:D

Now,

VB Code:

If strMytext = Lcase(strMytext) Then
'do something
End If

thank you so much, for some reason im not thinking right tonight :)

its still not letting me do it, same error, and it highlights where I am trying to set its autosize property to true!

Heres all the code (up till that point):

Code:

'Alistair D Baillie
Dim intPicCount As Long


Public Sub CreateGraphics(strName As String, strTheText As String)


Dim myPic() As PictureBox
Dim intNumberOfCharacters As Integer
Dim strTempItem As String
intNumberOfCharacters = 0
Do Until intNumberOfCharacters = Len(strTheText)
    intNumberOfCharacters = intNumberOfCharacters + 1
    strTempItem = Mid(strTheText, intNumberOfCharacters, 1)
    If strTempItem = LCase(steTempItem) Then
        strTempItem = strTempItem & "s"
    End If

    ReDim myPic(intPicCount)
    myPic(intPicCount).AutoSize = True
        myPic(intPicCount).Picture = LoadPicture(App.Path & "\" & strName & "\" & strTempItem & ".gif")
    intPicCount = intPicCount + 1
Loop

BTW, theres a limit to how many controls you can have, but I forget what it is.

lol

I think ive got around that problem with the code below (But it keeps getting stuck in a loop and crashing !!!)

Code:

'Alistair D Baillie


Public Sub CreateGraphics(strName As String, strTheText As String)
Dim intPicCount As Long
Dim intNumberOfCharacters As Integer
Dim strTempItem As String
intNumberOfCharacters = 0
intPicCount = 1
Do Until intPicCount = Len(strTheText)
strTempItem = Mid(strTheText, intPicCount, 1)
If strTempItem = LCase(strTempItem) Then
    strTempItem = strTempItem & "s"
End If
'Now lets put them into one image
main.CreatePicture.PaintPicture LoadPicture(App.Path & "\blue\" & strTempItem & ".gif"), main.CreatePicture.Width, 0
Loop
Call SavePicture(main.CreatePicture.Picture, App.Path & "\output\demo.gif")
End Sub

Hi guys,

Sorry to intrude.

AliBail's first method was OK. The problem was that you can't just redimension the array. You must also set the new objects in the array as new PictureBox.

You were also using redim which clears the array. This then means that none of the objects in the array have been initialized and will therefore give an object error.

below i have created a form2 object to be used in my array

________________________________________
dim lArray() as form2

redim larray(5) as form2
set larray(1) = new form2
larray(1).show
________________________________________

you will need to do this for each object in your array.

Also, in your loop, you are not changing the intpiccount nor the strTheText. Your loop will never end if the values don't change. This is always the first thing to check for in infanate loops cause we often forget to increment the values.

Yep, i noticed that and changed it;

Code:

'Alistair D Baillie


Public Sub CreateGraphics(strName As String, strTheText As String)
Dim intPicCount As Long
Dim intNumberOfCharacters As Integer
Dim strTempItem As String
intNumberOfCharacters = 0
intPicCount = 1
Do Until intPicCount = Len(strTheText)
strTempItem = Mid(strTheText, intPicCount, 1)
If strTempItem = LCase(strTempItem) Then
    strTempItem = strTempItem & "s"
End If
'Now lets put them into one image
main.CreatePicture.PaintPicture LoadPicture(App.Path & "\blue\" & strTempItem & ".gif"), main.CreatePicture.Width, 0
intPicCount = intPicCount + 1
Loop
main.CreatePicture.Refresh
Stop
Call SavePicture(main.CreatePicture.Picture, App.Path & "\output\demo.gif")
End Sub

The problem seems to lie with the fact that main.createPicture = 0 when I come to save it. Any1 know why it = 0? when ive been putting imags into it?
