Basically, what I'm doing is navigating to a website with a backgroundworker.In the WebBrowser1_DocumentCompleted event, I put code to fill in a form and I set the value of a boolean called "formFinished" to true once the form has been finished and submitted. The problem I'm having is that it only posts data to the second website, no matter the order of the websites. I'm wondering how this is possible since I have a boolean in state which only gets set to true once the first form has been submitted. So I have no clue as to why it only submits the second one, but not the first one.

View 1 RepliesI'm currently starting work on my first windows service and I've encountered what I find to be a strange error. For some reason the compiler is telling me that a whole bunch of typical classes (such as Image, Bitmap, Graphics, etc) do not exist. For example, these simple lines of code, which work perfectly in a normal project, return a bunch of errors:
Bitmap b = new Bitmap(destWidth, destHeight); //Error 13 The type or namespace name 'Bitmap' could not be found (are you missing a using directive or an assembly reference?)
Graphics g = Graphics.FromImage((Image)b); //Error 17 The type or namespace name 'Image' could not be found (are you missing a using directive or an assembly reference?)

Does automatic software update causes some of the module property not to work? They are basically the same function that reads image logo from the currently executing assembly. Function named "Get2LogoImageStream" is different from "Get1LogoImageStream" by just Current.ManifestModule.Name vs Current.ManifestModule.ScopeName.
This "Current.ManifestModule.Name " version of the code worked on both Web From app and Windows form app, however right now it only works for Windows App form. But when I changed this code "Current.ManifestModule.Name" with "Current.ManifestModule.ScopeName" and it worked on WEB without any problem. So my questions to fellow C# or VB.NET developers is that does automatic software update causes this kind of issues?
protected Stream Get1LogoImageStream()
{
Assembly current = Assembly.GetExecutingAssembly();
string imageName = "logo.jpg";

I am working on an OpenGL Visual Basic 2010 Express project using Tao.dlls.My computer has crashed a few times while I was last working on my code.Since then There has been some side effects such as intelisense and autocomplete not working when I load the project, even after checking the options and settings for them.When I start a new project on the other hand the features work again.Also when this OpenGL code is run:
Code:
glutMotionFunc(AddressOf MouseMotionGUI)
I get:
BadImageFormatException unhandeld
An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)
This code was working fine before my computer crashed and probably corrupted some files.
