Run-Time error '6' overflow. PLEASE HELP! AHHHHH

Here is my code for this program I have made when run it opens another external .exe in shell and sends keystrokes to it. This works in Windows 98 and Windows ME, but my beta tester that was on Windows 2000 got this error: Run-Time error '6' overflow

Code:

---

Private Sub Command1_Click()
End  'closes me
End Sub

Private Sub Form_Load()
Dim ID
    ID = Shell("bin/setup2.pif", vbHide)  'opens dos app setup2.exe in bin folder
Timer1.Enabled = True  'begins timer 1
Timer2.Enabled = True  'begins timer 2
End Sub

Private Sub Timer1_Timer()
AppActivate "Cleaner"  ' Sets sendkey window to cleaner
    SendKeys "{Tab}", True 'sends tab stroke
    SendKeys "{Tab}", True 'sends tab stroke
    SendKeys "{ }", True  'sends space stroke
    SendKeys "{Tab}", True 'sends tab stoke
    SendKeys "{Tab}", True 'sends tab stroke
    SendKeys "{Tab}", True 'sends tab stroke
    SendKeys "{ }", True  'sends space stroke
    Timer1.Enabled = False 'disables timer 1 from looping
End Sub

Private Sub Timer2_Timer()
Dim ID
    ID = Shell("bin/setup.exe", 1) 'opens setup.exe in bin folder
Timer2.Enabled = False  'disables timer 2 from looping
End Sub

Private Sub Form_Paint()  'tiles image1 on background of form1
Dim x As Integer, y As Integer
Dim ImgWidth As Integer
Dim ImgHeight As Integer
Dim FrmWidth As Integer
Dim FrmHeight As Integer
ImgWidth = Image1.Width
ImgHeight = Image1.Height
FrmWidth = Form1.Width
FrmHeight = Form1.Height
For x = 0 To FrmWidth Step ImgWidth
For y = 0 To FrmHeight Step ImgHeight
PaintPicture Image1, x, y
Next y
Next x
End Sub

What is causing this to happen? The appactivate? Send keys?
He said that my form opens up and that setup2.exe does execute once its open and the 'sendkeys' should occur he gets that error. What can be done?

I don't know what the problem is, but shouldn't your path Shell statements be Shell("bin\setup.exe", 1)? As for where it's happening, you can put in msgbox statements in your routines and narrow in on the error by noting which messages you get to.

BTW, why are you shelling from a Timer?

Well i didnt realize that I had put a forward slash instead of a backslash. I switched them around and well it still works. I'll have to wait for my beta tester to get on to try it out. (not guessing that is the problem though).
I'll try ur message box technique and see if that can tell me where the problem is, but its hard cause im on 98 and it works fine for me. It's good to have a patient beta tester though :p

You might also consider doing away with the timers. They look like they execute only once, but if they get out of control you could wind up shelling over and over again, and, while I think that would cause "out of stack space" errors - who knows?

The timers are the main workings of this project though.

This .pif program takes 3 seconds to load up after its called so I must sendkeys at exactly 3100 - 3500 in order for it to do its task properly. Unless of course I could figure out a way to sendkeys 'when app loaded' oer whatever, but im not sure how to go by doing that.

The speed of anything depends on the users PC so that could be a problem. Is the app a Windows app? If so then there are a number of ways to tell when it's loaded. (Probably also for DOS apps but I don't know.) One way is through the use of the GetWindowText API which looks for certain text in a window's title bar. If you want an example let me know. Another way (if you can modify the shelled app) is to simply have it create and write an "I am active" file after it's loaded and you loop looking for that file until it's found.

An example would be great!

I've looked around a bit but havent really gotten my hands on a good example.

thx

I must salvage this from the 3rd page cause i still need help :c(

This will launch NotePad..and wait for it to load before sendkeys! Just change to your app...

You should really try to avoid End in you app.
Its a bit too abrubt for a program to close.
use:

Code:

---

Private Sub Command1_Click()
  Unload me  'closes me
End Sub

---

It really closes all object and frees your memory...

Attached is the way I do it.

Doesnt want to work with the program I am trying to load. It's sending the keys before it shows up, giving me an error.

Well I mean, this code works great for me and I am on win98. It also works on winME.

So either appactivate or the sendkeys (i think) is giving win2000 the problem.

Not working :c(
grrr


I see where your coming from Martin, but it doesnt want to send keys in the form_load command (where i need it)
