Question

Hello.
I am working with winforms VB.NET VS2005
Inside my form I have net webbrowser component. After success loading PDF file into webbrowser1 my application gives error on closing.


The instruction at "0x08a0609c referrenced memory at "0x00000014". The memory could not be "read".
What the best way to get it working.
Close application without loading pdf file does not give error.

Thank you
Michael

Hi,
The exception tells nothing, we need to find the inner exception ourselves by debugging your source code, it will be helpful for further investigation if you can post the exception details here.

Thanks,

Hello

I am using WebBrowser Control inside windows form

I am using Webbrowser1.navigate(filepath)  code many times.
User inputs part of pdf filename and I add extension. After that I an searching in our network and load it in case it was found.
It's happened on close of application(Application.Exit action) after user many time uses this search

Here is the code:

Private

 

Sub btnSearchJob_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearchJob.Click

WebBrowser1.Navigate(

"about:blank")

 

Dim JobNumber As String = Me.txtJobNumber.Text.Trim

 

Try

 

Dim filePath As String = getFileLocation(JobNumber & ".pdf")

 

If Not String.IsNullOrEmpty(filePath) Then

WebBrowser1.Navigate(filePath)

 

Else

ShowMessage(

"Such number does not exist")

 

End If

 

Catch ex As Exception

 

End Try
