I want to test out a code line with about 50,000 characters over about 7 lines, but VB takes about 2-3 minute breaks for every line of code I change and it crashes every 1-5th try. I moved the code into a public shared sub in a new class, and closed the class tab, but still VB can't resist checking though the code all the time.Is there any way I can prevent VB from checking that class/code?

I recently downloaded the Windows API code pack for .net, and seeing there was VB.net examples inside there, I opened them up. Upon building I get a warning that the referenced components 'Core' and 'Shell' could not be found. Looking in the code pack folder I see there are no DLLs at all, but instead a whole load of C# sources.
Do I have to download C# Express (which I want to avoid) to use the code pack or are there precompiled DLLs somewhere?

I had a weird series of errors involving e.Graphics.DrawString() when painting a panel.I am using a barcode font [Code 128] with a library that converts text to the proper format for Barcode readers.That's fine, however, when I draw it to the panel, that's where things stop being fine:But, here's where things get funky. When I put it into a TextBox instead of drawing it via Graphics.DrawString(), everything is peachy:In fact, the TextBox one looks much better than the Graphics.DrawString() one!

View 1 RepliesFor logging purposes, some methods in our application include the following line:Dim Log As ILog = GetLog(Reflection.MethodBase.GetCurrentMethod().DeclaringType)I have what might be described as an irrational fear of reflection, which I try to keep in check. However, calls like this in methods that are executed potentially a hundred times a second concern me. I don't know as much as I should about reflection; but from looking briefly over the documentation, it looks to me like I could replace the following with:Dim Log As ILog = GetLog(Me.GetType())My question is three-fold:Does Me.GetType() actually return the same Type as GetCurrentMethod().DeclaringType? Does Me.GetType() actually do anything differently from GetCurrentMethod().DeclaringType, or is it doing the same thing under the hood?

This is, of course, very buggy and causes a lot of violation errors etc. But that doesn't matter right now. How come the multi-threading way is so much faster than the regular routine? Is the processor not running on full speed with the first code, and is it working harder on the second?I find it weird to see this type of "threading performance increase", as if every single thread gets their own piece of processor speed allocated like it is a new process
I tried to start using VB 2010 Express with a program I originally developed with VB 2005 Express that I moved to VB 2008 Express successfully a couple years ago. It uses a database file (*.mdf) that is on the computer ( not out on a server). When attempt to run the program in debug mode, I get the following error "An attempt to attach an auto-named database for file C:Documents and SettingsTomMy DocumentsQuizzing StuffQuestion Database 2010QuizQuest ionGameQuizQuestionGameinReleaseQuizQuestionDB.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share."
I first made a copy of the entire project folder that was working in VB 2008 Express and gave it a different name. In VB2010 I opened the project in the copied folder and it said it successfully converted the project. I am able to open the Data Source inthe Designer and see the database structure as I expect. I think the project is still using SQL Server 2005 Express (because it is what is checked in the list of prerequisites on the Publish tab).
Note, I have programmed off and on for many years, but fairly new to using databases and SQL Server.
Can i get text from a textbox and use that text for the second forms code?
