        If TextBox3.Text = String.Empty Then
            MessageBox.Show("Please enter a subject", "Subject Required", MessageBoxButtons.OK, MessageBoxIcon.Error)
        End If

        End If
        Dim abc As Integer
        Dim X As Integer
        X = -1
        If TextBox6.Text = String.Empty Then Exit Sub
        For abc = TextBox5.Text To TextBox6.Text Step 1
            WebBrowser1.ScriptErrorsSuppressed = True

            X = X + 1
            Label4.Text = abc
            Label7.Text = X
            Me.Refresh()
            Try

            Catch ex As Exception
                X = X - 1
            End Try
            While WebBrowser1.ReadyState <> WebBrowserReadyState.Complete

Reverend Jim, I completely agree since I also created an automated p.m.s'er:D to send p.m.s:D to those that did not mark their threads Solved or just abandoned their threads, and it did use the _wb_DocumentCompleted event.

Had a chance to play w/this for a few minutes, though I could Not test.

Public Class Form1
    Private isSendingPMSxD As Boolean = False '// alert wb that it is a p.m. page.
    Private iStartID, iEndID As Integer

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        WebBrowser1.ScriptErrorsSuppressed = True '// disable Error.Messages.
    End Sub

    Private Sub showCoolMessage(ByVal selCoolMessage As String, ByVal selCoolTitle As String) '// just.because.
        MessageBox.Show("Please enter " & selCoolMessage, selCoolTitle & " Required", MessageBoxButtons.OK, MessageBoxIcon.Error)
    End Sub

    Private Sub _Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
        With TextBox3 : If .Text = "" Then : showCoolMessage("a subject", "Subject") : Exit Sub : End If : End With
        With TextBox4 : If .Text = "" Then : showCoolMessage("a message", "Message") : Exit Sub : End If : End With
        With TextBox5
            If .Text = "" OrElse Not IsNumeric(CInt(.Text)) Then : showCoolMessage("start ID to PM", "Start ID") : Exit Sub
            Else
                iStartID = CInt(.Text)
            End If
        End With
        With TextBox6
            If TextBox6.Text = "" OrElse Not IsNumeric(CInt(.Text)) Then : showCoolMessage("end ID to PM", "End ID") : Exit Sub
            Else
                iEndID = CInt(.Text)
            End If
            : End With
        isSendingPMSxD = True
        wbNavigate(iStartID)
        Button3.Enabled = False
    End Sub

    Private Sub wbNavigate(ByVal selCoolIDtoUse As Integer)
        WebBrowser1.Navigate("http://forum.ea.com/uk/pm/sendTo/" & selCoolIDtoUse & ".page")
    End Sub

    Private Sub _WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
        If isSendingPMSxD Then
            With WebBrowser1.Document
                .GetElementById("subject").SetAttribute("value", TextBox3.Text)
                .GetElementById("message").SetAttribute("value", TextBox4.Text)
                .GetElementById("btnSubmit").InvokeMember("click")
                Label4.Text = iStartID
                Application.DoEvents()
                If Not iStartID = iEndID Then
                    iStartID += 1 : wbNavigate(iStartID)
                Else
                    isSendingPMSxD = False
                    MsgBox(".done.")

Since I cannot test it(no EA acct.), Not much at all I can do about it. Wish you luck and glad that I could be of help so far.:)

q.q.(quick.question)
Have you tested to see If it still has the memory leak?

.idea/suggestion.
Have you tried this w/multiple WebBrowsers?

Can't comment on the WebBrowser portion but I do have a couple of things to point out. You can replace each block of

If TextBox3.Text = String.Empty Then
    MessageBox.Show("Please enter a subject", "Subject Required", MessageBoxButtons.OK, MessageBoxIcon.Error)
End If
If TextBox3.Text = String.Empty Then Exit Sub

with

If TextBox3.Text = String.Empty Then
    MessageBox.Show("Please enter a subject", "Subject Required", MessageBoxButtons.OK, MessageBoxIcon.Error)
    Exit Sub
End If

Also

For abc = TextBox5.Text To TextBox6.Text Step 1

For loops require integer parameters. You have declared abc as integer, however, TextBox5.Text and TextBox6.Text are not integers. You should convert these to integer values (after ensuring that the strings are in fact valid integers).

done changes fellah, thank you, but still its increasing and stacking until forever, :(

any other ideas?

I just thought I'd answer the question you didn't ask. Sorry, but I can't help you with the WebBrowser stuff.

Begginnerdev 256 Junior Poster · Answer 4 · 2012-01-25T03:54:34+00:00

Did you try removing the second

WebBrowser1.ScriptErrorsSuppressed = True

And...

For abc = Cint(TextBox5.Text) To Cint(TextBox6.Text) Step 1

codeorder 197 Nearly a Posting Virtuoso · Answer 5 · 2012-01-25T08:28:47+00:00

Just taking a wild guess here; I think that this might be the cause of the issue.

While WebBrowser1.ReadyState <> WebBrowserReadyState.Complete
                Application.DoEvents()
            End While

Try commenting out the Application.DoEvents() and report back.

The WebBrowser1.ScriptErrorsSuppressed = True can be set "only once" in Form1_Load and it will take care of all Script.Error Messages andOr can be set in the wb(WebBrowser)'s Properties.

Completely uneducated suggestion here, but I noticed that the WebBrowser control has a DocumentCompleted event. Why not use that instead of a wait loop?

daydie 12 Junior Poster in Training · Answer 7 · 2012-01-25T17:21:23+00:00

i dont know how to do that Jim or i would im new to this coding stuff ya see. can u write the code (Document Complete) that i can do to replace the loop but still acts like one?

Cheers

Can't do. I've never programmed a web interface. The best I could do was make an off the wall suggestion that I hoped might point you in the right direction.

daydie 12 Junior Poster in Training · Answer 9 · 2012-01-26T06:14:36+00:00

Ah awsome, one problem, after first pm, it tryed to search for subject again before its even reloaded.

codeorder 197 Nearly a Posting Virtuoso · Answer 10 · 2012-01-26T07:32:03+00:00

Can you provide more details?
.btw, did it take care of the "memory increase leak"?

daydie 12 Junior Poster in Training · Answer 11 · 2012-01-26T08:08:35+00:00

it was loading the next id to PM but it could not find "Subject" because it did not load completely and crashed, i tryed to "Try" them out but then its flicks through all the ID's nearly instantly.

Cant check memory leak due to this fella. how can i make it wait for page load? as i thought it shud as its in Webbrowsercomplete section.

codeorder 197 Nearly a Posting Virtuoso · Answer 12 · 2012-01-26T09:56:54+00:00

.Replace the entire _WebBrowser1_DocumentCompleted event w/this.

Private Sub _WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
        If isSendingPMSxD Then
            Application.DoEvents()
            tmrWb.Start()
        End If
    End Sub

    Private WithEvents tmrWb As New Timer With {.Interval = 500}
    Private Sub _tmrWb_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles tmrWb.Tick
        Static iTimeOut As Integer = 0
        If Not iTimeOut = 3 Then '// roughly 1.5 sec.
            iTimeOut += 1
            Exit Sub
        Else
            iTimeOut = 0 '// reset timeOut.
            tmrWb.Stop() '// stop timer.
            With WebBrowser1.Document
                .GetElementById("subject").SetAttribute("value", TextBox3.Text)
                .GetElementById("message").SetAttribute("value", TextBox4.Text)
                .GetElementById("btnSubmit").InvokeMember("click")
            End With
            Label4.Text = iStartID
            If Not iStartID = iEndID Then
                iStartID += 1 : wbNavigate(iStartID) : Exit Sub
            Else
                isSendingPMSxD = False
                MsgBox(".done.")
                Button3.Enabled = True
            End If
        End If
    End Sub

I added a Timer to give it a TimeOut. Set the Timer's.Interval as needed, If needed.

quick.suggestion before .Replacing the event:
.Add "Application.DoEvents()" as the very first line of code in the wb.doc.completed event. Might or might Not Return results.

If "this fella" is Waldo, I'll never get an answer, cause I can never find his butt anywhere.:D

The timer is usefull and works but will at alot of time to the duration over x hours. any chance to fix the page load thing fella?

and thank you for all your help so far

daydie 12 Junior Poster in Training · Answer 14 · 2012-01-27T20:58:13+00:00

no memory leak :) no fella i aint i tryed to adjust it to use multi browsers but i had no luck lol do u mind adding a few maybe 4?

Here are some notes.
Add your 4 wb's and add 4 Timers.
Other than that, good luck.:)

awsome yeah i done that, but i mite change bk to one, and allow them to open multi programs for more speed.

btw any way to make this wait until page load and not timer?

codeorder 197 Nearly a Posting Virtuoso · Answer 17 · 2012-01-30T08:01:24+00:00

See if this helps.

Private sInnerHtml As String
    Private Sub WebBrowser1_DocumentCompleted(sender As System.Object, e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
        sInnerHtml = WebBrowser1.Document.Body.InnerHtml
        With sInnerHtml.ToLower
            If .Contains("=""subject""") AndAlso .Contains("=""message""") AndAlso .Contains("=""btnSubmit""") Then
                '// run code here to post.
            End If
        End With
    End Sub

.might need a space here and there, though it should take care of the issue of Not using a Timer.

            iTimeOut1 += 1
            Exit Sub
        Else
            iTimeOut1 = 0 '// reset timeOut.
            tmrWb2.Stop() '// stop timer.
            If Not iStartID = iEndID Then
                iStartID += 1 : wbNavigate(iStartID) : Exit Sub
            Else
                isSendingPMSxD = False
