[RESOLVED] Waiting for a webpage to load?

[juanchoc]

Hello!
I have a problem with timers starting before a document finished downloading on a webbrowser.

Thake this as a example:
sub something()
wbBrowser.Refresh
tTimer.Start
end sub

The webbrowser starts refreshing and the timer starts instantly.
What i need is to wait until the document has loaded for the timer to start.
But its not as easy as moving the tTimer.Start to the wbBrowser.DocumentCompleted event, because i need this only on that refresh instance.
I mean only to happen like that when the refresh method is called from inside the sub something.

Did i make my self clear?
Because its a bit hard to explain lol

Well, thanks in advance.

Well i tryed this now:

sub something()
wbBrowser.Refresh

Do While wbBrowser.IsBusy = True
Application.DoEvents()
Loop

tTimer.Start
end sub

But with no sucsess.

Are you setting IsBusy to False in the Document Complete event?

[juanchoc]

Hmm no.
Should i?

Sory im kinda new to vb

Btw, IsBusy is readonly, how am i supposed to set it to false?

[dglienna]

Well, this is from VB6, but you could create your own variable, and after calllng the document, set the value.

blnBusy = True
Do While blnBusy = True
Loop

And then set it to false in the Complete event.

[juanchoc]

But the problem is that if i use the DocumentCompleted, ill be waiting for all the webpages displayed on my program to be completed.
And what i need i that just on that request, thats been made on that sub.
Got it?

Thats why i thought maybe if i make the program go in a do while loop while the browser is busy, it should "wait" until its idle to continue with my code.

[juanchoc]

Isnt there any way of stoping code execution until one exact page finished loading?
I mean i can use the DocumentCompleted method but that will afect all of the webpage loading that apears thou all my program, and i just need this to happen on only one sub and anywhere else of my code.

[juanchoc]

Hmm sory for the posting number lol

Here is the code so its easyer to understand what i mean:

    Private Sub tTimer_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles tTimer.Tick
        tTimer.Stop()
        tClock.Stop()

        wbAutoBrowser.ScriptErrorsSuppressed = True

        If Refreshed = True Then
            DeparseUrls()
            Refreshed = False
        End If

        If j >= 0 Then
            wbAutoBrowser.Navigate(Url & results(j))
            j = j - 1
            tTimer.Interval = ClickWaitInterval
        ElseIf j < 0 Then
            tTimer.Interval = BrowserRefreshInterval
            wbBrowser.Refresh()
            Refreshed = True
        End If

        Do While wbAutoBrowser.IsBusy = True
            Application.DoEvents()
        Loop

        Do While wbBrowser.IsBusy = True
            Application.DoEvents()
        Loop

        dStart = DateTime.Now

        tTimer.Start()
        tClock.Start()
    End Sub

As you can see i tryed to make the application enter the do while loop until the browser is idle, and the continue and start the timers.
But for some strange reason it never enters none of the do while loops!
In theory this would solve my problem, but for some reason it just doesnt work.
So if someone helps me make it work ill be really thankful

Well, now i tryed two other thing, but with no succsess...

        Do Until wbAutoBrowser.ReadyState <> WebBrowserReadyState.Complete
            Application.DoEvents()
        Loop

        Do Until wbBrowser.ReadyState <> WebBrowserReadyState.Complete
            Application.DoEvents()
        Loop

        Do While wbAutoBrowser.ReadyState <> WebBrowserReadyState.Complete
            Application.DoEvents()
        Loop

        Do While wbBrowser.ReadyState <> WebBrowserReadyState.Complete
            Application.DoEvents()
        Loop

Any sugestions?

[juanchoc]

Well after furter research about the ReadyState property, i tryed this:

        Do Until (wbAutoBrowser.ReadyState = 4) Or (wbAutoBrowser.ReadyState = 0)
            Application.DoEvents()
        Loop

        Do Until (wbBrowser.ReadyState = 4) Or (wbBrowser.ReadyState = 0)
            Application.DoEvents()
        Loop

And this:

        Do Until (wbAutoBrowser.ReadyState.ToString = "Complete") Or (wbAutoBrowser.ToString = "Uninitialized")
            Application.DoEvents()
        Loop

        Do Until (wbBrowser.ToString = "Complete") Or (wbBrowser.ToString = "Uninitialized")
            Application.DoEvents()
        Loop

But neither of those two are working...
This is really starting to piss me off lol
I dont see what im doing wrong, can someone point me in the right direction please?

Thanks in advance,
JCC

[juanchoc]

Wow finally solved!
Well after trying a lot of things i got an idea that worked like a charm!

Instead of using the DocumentCompleted method, that wasnt working to me, Im using the ProgressChanged method and i add a If and a boolean. Like this:

If e.MaximumProgress = e.CurrentProgress Then
            AutoBrowserComplete = True
        End If

And this on the other sub:

Do While BrowserComplete = False
            Application.DoEvents()
        Loop

Please Congratulate me! lol
This was a hard one, and theres no mention of doing it like this on any other site

I know this is an old post, but anyone who finds this could also try:

Do Until WebBrowser1.ReadyState = WebBrowserReadyState.Complete
            Application.DoEvents()
        Loop
