VS 2008 Validate A Groupbox To Make Sure Radiobutton Is Checked - VB 2008

May 12, 2010

Is there a way to validate a groupbox with a couple radiobuttons in it to make sure that one of the radiobuttons is selected?

Heres why I need this. I need a user to be able to select their class rank out by way of radiobuttons in a groupbox. When they click submit, I need to validate that atleast one of the radiobuttons got selected and if not display a messagebox.

I got one reply early of:

If myGroupBox.Controls.OfType(Of RadioButton).Count(Function(rb) rb.Checked) = 0 Then
'There is no RadioButton checked in myGroupBox.
End If

Is there any other ways other then that? Preferrably a more 'dumbed' down way? This is for just an entry level VB class, I would prefer not to use something of that nature if there is another way.

How To Enter Serial Number Into Registry

Feb 7, 2009

I am trying to release my program now and I have a quick (hopefully quick) question concerning serial numbers. I want to be able to store the trial serial number so if the user uninstalls and reinstalls they won't get another evaluation period free of charge. My concern is that some crafty person will simply move the database files in and out of those installs and keep going indefinately. Although I have some protections built into the database itself in case the program runs out, I just want one extra layer of protection. Is there a way to store the serial number in the registry when entered and check for that entry whenever the program is installed using Windows Installer 3.1?

VS 2008 Serial Data - Make Sure The Correct Data Is Received?

Jun 28, 2009

I am using Visual Basic express to create a serial interface to a multi-room audio controller. I have started by creating a form that can connect to the controller and I can receive data from the Controller and display Zone status, volume etc in corresponding texts box thaks to help from Stanav and Tassa in my previous thread.

My next problem is to do with receiving lots of data from the serial port and my application getting out of sync. This is mainly caused by turning the volum control as each time it is turned a little bit the controller sends out the new status of the Zone being effected

eg
****Turning Volume knob on Zone 1***
Status returned from Controller:
#Z01PWRON,SRC3,VOL05<CR>

VS 2008 Protect Product Obfuscation?

May 19, 2009

I've developed a product, I now want to protect it from reverse engineering and decompilation, can anyone share some info about this..?I'm looking for the BEST product out there, for doing this, I want to make it a pain to decompile or reverse engineer my product =)Does anyone know of any? or any other products that do other things that can help protect it, for example, I once found a program which converts ALL your .NET exe, into a C++ exe file, so it's not .NET code anymore, fully machine code or something like that (can't find it anymore though).

I thought posting here would be a good idea, since, a lot of you are very experienced with developing products, and perhaps some of you have used obfuscator's to protect them.

First/Last Name must have no spaces, Course must consist of a three letters and two numbers in that order and nothing else(I want to avoid the use of masked text box), and Email must have the "@" sign and a dot. How would one make it so after clicking, say, Submit button and if there was a violation of any of the above rules then message box should pop up and tell the user which fields contain incorrect information.

Private Sub buttonAddNewStudent_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles buttonAddNewStudent.Click
