VS 2008 Call Sub AFTER DocumentCompleted?
Apr 2, 2010
I currently have two subs in Webbrowser3.DocumentCompleted. The first sub scrolls the web page to a specific point. The second sub takes a screenshot of the webbrowser window.Problem: Screenshot image is recording the top edge of the webbrowser. This means it is not scrolling to the right position before snapping the screenshot.
My guess is that the web page is not fully loaded when DocumentCompleted is called. Or the scroll is not being completed til after the screenshot has been taken. Result: After this is run, I end up with an image of the top edge of the browser. The Webbrowser is scrolled to the right place, but the image is taken before it gets there.

Home.Browser0.Document.Forms(0).All("menu").SetAttribute("value", item1)
Home.Browser0.Document.Forms(0).All("menu").RaiseEvent("onChange")

This is a good way to use DocumentCompleted using AddHandler (good for a tabbed web browser) [code] Of course,.you can adapt this for a tabbed WebBrowser by replacing me.text with tabcontrol1.SelectedTab.Text.

I have some experience developing for VBA inside Office apps, but I am quite new to VB.NET, and I just noticed that its WebBrowser control is a bit different from that one I used to reference via ShDocVw to use in my VBA Forms.ShDocVw.WebBrowser had the DocumentComplete event, which passed these arguments: URL as string and pDisp as object..NET WebBrowser has the DocumentCompleted event, in which i successfully found e.URL.ToString, but I couldn't find nothing similar to the pDisp object.
This is critical to me on migrating my project from VBA to VB.NET, for I need to handle particular IFrames when they complete loading, which I only could do by getting pDisp's document property. So I need help on learning how to do the same thing with this .NET WebBrowser control, and/or how to reference and use good ole ShDocVw.WebBroser in my Visual Studio project, to embed it in my forms.

I connected to the Informix server using RazorSQL, created a stored procedure and tested it, getting the expected answer, so the procedure exists in the database in some form.
I then run the following code:
If ConnectToInformix() Then
Dim cmd As New IfxCommand("dc_routeHasOutstandingQuantity", conn)
cmd.CommandType = CommandType.StoredProcedure
[Code]....
This error does not occur when calling the stored procedure from a live SQL connection.

I want to create an ExpressionTree where a Func(of Vector, Vector, Vector, Vector, Double, Double, Vektor) should be called. So I use
Expression.Call(Forces(0).Function.Method, {Vec1, Vec2, Vec3, Vec4, Double1, Double2})(Vec1-4, Double1-2 are declared as ParameterExpression and Forces(0).Function as Func(of Vector, Vector, Vector, Vector, Double, Double, Vector). But I get an AgrumentException, because Forces(0).Function.Method has seven Arguments. (System.Runtime.CompilerServices.Closure as seventh argument at Index 0).

I have created a small exe that receives some arguments, then creates and start a process (runs ghostscript) to create a png image of a pdf.The whole system works fine except when the exe is called more than once at the same time. My understanding is that i thought it would create a new instance each time it is called, but this doesnt seem to be happening.Is there a way i can 'queue' the requestes to exe so that the previous request completes then the next one begins and so on.[code]

I'd like to be able to call a Paint Sub that is framed like what you see immediately below from another sub but haven't been able to figure out how to do it yet. I'm working with option strict on.
Private Sub DisplayGraphics_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me.Paint
End Sub
What would I put inside the parentheses to satisfy the arguments for the above sub DisplayGraphics_Paint().
DisplayGraphics_Paint(?, ?)
Perhaps I should modify the code for the Paint sub to do what I'm trying to do.

I have created a project using VB.Net(VS2008) and created the exe file. I have another project in VBA (Excel 2003). The project basically IC-Testing based. So according to the device type the Excel workbook name varies. For example I have AAAA.xls, BBBB.xls, CCCC.xls. When I open AAAA.xls, I want to call the .exe (which is developed in VB.Net) with the variable "AAAA". i.e when the exe program runs, it knows which Excel is opened or from which Excel the .exe is called. now I am using Shell retval=Shell("d:Monitor.exe",1). Using this the exe is called and running fine. But the Monitor.exe doesn't know which Excel called it, whether it is AAAA.xls, BBBB.xls or CCCC.xls.

I have a routine that will connect to a tcp server and then disconnect which works perfect. It checks the connection to another program on another pc which is what I need. But if the computer is not on or the ip address is not valid, it takes a bit for it to time out and continue on.

In my Zeal to get with the "Dispose" program, I implement a dispose pattern (still learning the ways and means of THAT) wherever it seems to make sense.I THINK I have the basic idea. However, I notice that, while Drawing.Brushes HAVE a Dispose method, when I call it, some sort of instability is created in Visual Studio itself, and i get the dreaded "Visual Studio has encountered an error and needs to close" splash screen, with no useable error information. SHould I assume that one should just NOT call dispose on Brush objects, or is there something I am missing here: [code]

I tried the search (forum / google) before, but unfortunately I found no solution. From VB.NET I have to call a very old c-dll, the methods have signatures like this:[code]In VB I tried the method-declaration with IntPtr, FixedLengthString, Char(), Byte() and so on, but with no success. I now, that char* declarations can be handled with the Stringbuilder, but that seem not to work in this case, as the declaration is a char[256] and no pointer.So how to declare the c-method above to be used in VB.NET?

I have a bunch of VB.NET programs that have a general purpose logging function to log events, errors, exceptions, etc. It looks like this:
Sub LogMe(Msg as string)
LstLog.items.add(now.tostring & " " & Msg)
End Sub
I wrote a few VB.NET DLLs that contain classes used my my VB.NET programs. In thoses DLL classes, I would like to also trap some events, errors, exceptions, etc. But I want them to be logged using my main LogMe function. Here is some pseudo-code of what I was looking for:
' Main program code
imports MyLib
' Initialize program
[Code]...
I assume I will need to define Delegates to save my LogMe fonction pointer

I know that it's possible to Call a stored procedure from a Windows Application made in VS 2008. But, is it also possible to Create one? If so, isn't it possible for someone to create a SP that will delete all the data in a DB,when executed? Is there a real danger that someone could use an application that communicates with a DB to create such a procedure?

Can a BackgroundWorker call additional subs? In my program I am connectiong to an OPC Server. I am doing some AsynReads, which in themselves don't take anytime. But Once I get the AsyncReadComplete returned, I want to do the AsyncRead right away. Basically I need to Loop them. The problem now is that while it is doing this, Everything is unresponsive, because it is just going through the loop. So to perhaps rephrase the question, If the BackgroundWorker initiates a process (in this case AsyncRed) would the returned AsyncReadComplete be apart of the BackgroundWorker or seperate Thread?
