my program has a lot of pictures...i have it programmed so one pic will show and then disappear then the next picture will show and then disappear...but, it takes like forever for the program to load...the code i have goes like this

form_load
image1.visible = true
image2.visible = false
image3.visible = false
(and it goes all the way up to image20)

then i have my timer set to 2400
everytime the timer clicks...
if image1.visible = true then
   image1.visible = false
   image2.visible = true
and this goes on up to image20

is there an easier than typing all of this??
and how can i make the loading process faster???

thanx

You can create an array of picture controls, just give them one name, like Pic1, and set their index properties from 0 to 19
Then u can use loops to hide all of them in a few lines, and show only the one u need

This is were a resource file comes in real handy.

If you don't have the resource file editor from VB's owners area, I suggest you install it. It's free and will make things a lot easier.

Anyway, I've created a resource file with 750K worth of bitmaps in it. I named them 101-125 then placed the following code in a form:

Option Explicit

Private lPicPointer As Long

Private Sub Timer1_Timer()
    If lPicPointer < 101 Then
        lPicPointer = 101
    End If
   
    If lPicPointer > 125 Then
        lPicPointer = 101
    End If
   
    Picture1.Picture = LoadResPicture(lPicPointer, vbResBitmap)
   
    lPicPointer = lPicPointer + 1
End Sub


The compiled program came out to 800K, loaded really fast, and there's not much code to cycle through the pictures.
