hi guys i got an error can u help "run-time error 91 object variable or with block v"

hi guys i got an error can u help "run-time error 91 object variable or with block variable not set"

my application imports a list from a text file and shells each line and tests the results.
i am using these functions

while loops
do while loops
goto commands ("i know its bad :)")
i have text boxes
im using 3 timers
and using webbrowser

without me posting my entire code here could you give me a clue as where to start looking please :)
and i only seem to get this error after a few loops of the entire process. not quite sure why it would error out as the first few times were successfull

BTW im jerry nice to meet you all

The most likely thing, given the small amount of information available, is that you are attempting to access a Document returned by the WebBrowser before it has been completed. How are you waiting for the Document to be completely loaded when using the WebBrowser?

hi thanks for quick reply
i am using a wait method of 5 seconds#then i also have a

dim mycounter as integer
do while webbrowser1.busy = true
mycounter = mycounter + 1
if mycounter > 10 then exit do
wait(1)
do events
loop
mycounter = 0 "just put this command in to test incase that errors out after a few loops"

edit
nope that didnt do the trick

you have got me thinking.
i have a loop that timesout after ten seconds .
i have just added a
webbrowser1.stop
im hoping that works

nope that didnt work but it did do 6 loops before error

Show us the line where the error occurs and the code around it

ok here is my entire sub. it is suppose to test the existence of a page true or false

Private Sub netcheck(mylink)
Dim sHTML As String


WebBrowser1.Navigate (mylink)

wait (5)
Dim mycounter As Integer

Do While WebBrowser1.Busy = True
mycounter = mycounter + 1
If mycounter > 10 Then
mycounter = 0
WebBrowser1.Stop
Exit Do
End If
wait (1)
DoEvents
Loop
mycounter = 0


sHTML = WebBrowser1.Document.documentElement.innerHTML

If InStr(1, sHTML, "The page cannot be found") > 0 Then
internetcheck = "false"
ElseIf InStr(1, sHTML, "server not found") > 0 Then
internetcheck = "false"
ElseIf InStr(1, sHTML, "page cannot be displayed") > 0 Then
internetcheck = "false"
ElseIf InStr(1, sHTML, "Navigation to the webpage was canceled") > 0 Then
internetcheck = "false"
ElseIf InStr(1, sHTML, "Action canceled") > 0 Then
internetcheck = "false"
Else
internetcheck = "true"
End If


End Sub

what you should be doing is using the DocumentLoad event instead - http://msdn.microsoft.com/en-us/libr...(v=vs.85).aspx

the only issue with that is it doesnt appear to have a timout function.
plus i rerun the code above and it seems to not have the error anymore :)

thankyou for helping me pinpoint this issue

i am getting another error also
run-time error 6 overflow
i seem to get this after i stop my script and then start it again and 2 loops in exactly the error will happen
or if i get a msgbox telling me there were timeouts and then i press ok and after exactly 2 more loops it will give this error
any ideas what could cause this overflow error

Have you tried debugging your code? Debugging Your Code and Handling Errors teaches you how.

i have thought about that but i am using visual basic on my server and the application i am building changes settings in the ip address dns ect.
i am running the application on a separate laptop for testing. is there a way i can build the exe and any error it could msgbox i ?

Call the following procedure from various points in your program. You should pass in a string of text which indicates the current location of the code executing in your program. Read more...
