I am new to vb.net. I created a vb.net script to autogenerate a code. Now, after generating this code, what I want is to determine the validity of this code. for example, a code has been generated now and this code will be valid for 24 hours only.
Below is my script for the auto generation code

For i As Integer = 0 To 9999
randomhold = randomvalue.Next(1, 9999)
newcode = randomhold & DateTime.Now.Minute & DateTime.Now.Year
Label3.Text = newcode
Next
The code generated will be sent via sms. If the code hasn't used within 24 hours, it will be invalid.

i'm worried about doing this since my changes will be overwritten when the dbml file is auto generated again (as they often are).i'm thinking of doing a partial class and writing out the same properties to annotate them, but worried that it will complain about duplicates, and the reason i can't even experiment brings me to the second part of my questions...
that, the expandable arrow on my dbml file listing is missing, right clicking and selecting "View Code" just displays an empty partial class as below.

View 2 RepliesI am trying to use a script mananger to use page methods to communicate between the server and client side of my page. I have added this code to the html

According to the General Naming Conventions the usage of CLR type names (e.g. String, Int16) should be preferred over the usage of language specific type names (string, short). I usually follow this advice. Resharper however seems to use the language specific type names when generating code (eg. when extracting methods or generating foreach loops) which is very annoying.

View 3 RepliesI don't know what's got into them but they decided to purchase vs2010 pro licenses in my company. Anyway i gave it a quick look and since i don't need to have it installed right now (service pack 1 first, Microsoft anti-bug law) i uninstalled it. The problem i see is that it leaves leftovers everywhere.C++ redist, ado components, sql r2 components etc. These will not be deleted if i just remove vs2010 but will be installed if i install vs2010 full.Anyway i ended up removing them one by one and it took about 30-45 minutes. So has anyone have done a removal? Is this the case? I cannot remove most of the components with one big uninstall?
View 2 RepliesI would like to create a new form within my project that is identical in terms of the controls and components of one of my existing forms. The difference will be in the code where I will change some constants.
Is there a way to copy the controls and components(text boxes...) so that I don't have to use the design mode to create the form again?
I've tried copying the code of the original form and pasting it into the new form, however it only pastes the code and not the actual buttons and texts boxes.
