Visual Basic always running old codes

[TqLxQuanZ]

As the titles said, my visual basic 2010 express always runs my old codes, not the latest one. Even adding the pictureboxs,label, etc, also using the old ones.
I've searching for tons of solution through google but most of them not working.
Except copy and paste all my works to another new project, any idea how to fix this bug?(My project contains too many forms so i can't one by one copy them all)

Sorry for bad english.

I don't understand the question, but it's possibly because of your bad English.

Do you want to update your old code to new code?
Do you want to continue to use your old code, but it is not working any more?

Clean the project... this happens from time to time when the build folder doesn't get updated. I've still yet to see a pattern of any kind. It's pretty sporattic and random. Cleaning the solution/project is one solution, the other is to delete the bin & obj folders. Either way, it usually helps.

Are there any errors listed in the Error List (at the bottom in Visual Studio)? If there are, then you're app isn't actually compiling and it will run the last successful compile of your app, you have to fix all of the errors for it to compile again.
