View 1 RepliesIt has been a long time since I have programmed. What I need to find out is how to make my VB 2008 Express Edition program read a text document so that I can alter the text. What I have been doing instead is cutting-and-pasting the whole text into a TextBox by hand and then writing:
t = TextBox1.text
and using mid() to find parts of variable t.I am not sure that this will work though because some of the files are very big (as much as 583 Kb. (I am unsure how much data can be put into a single variable.
I have a vague memory that when I was using VB5 on a similar project years ago, I had to type maybe four lines of code at the beginning that were all lines I just copied from somewhere and that were lines I did not understand.
I create a new Windows Forms application and add an AboutBox form which is built-in into Visual Studio. I add a button to Form1 to show the AboutBox when clicked.The AboutBox form has a label with the text "Version" on it. The following code is supposed to add the application's version to that label at run-time:
Me.LabelVersion.Text = String.Format("Version {0}", My.Application.Info.Version.ToString)When the application version is changed in the Publish tab of the My Project form to 2-0-3-6, the version on the AboutBox at run-time stays at 1.0.0.0 (of course after rebuilding).
Even when the application is published to the desktop, it still does not work. It does, however, reflect the correct version number in the title of a subfolder in the Applications folder that is created when the application is published.

I have 16 student machines who can not access the windows live login during the school hours due to filtering restrictions. They need to register Visual Basic 2008 Express Edition within 30 days or the product becomes useless. The registration process wants them to login to access the keys.

My company currently has vb.net 2003. I am tasked with evaluating vb.net 2008. And suggest if upgrading to 2008 edition is necessary or if it will be beneficial. For this purpose I decided to experiment with vb.net 2008 express. I have some questions regarding this.
