Change CSS File Dynamically?
Jun 1, 2011I have close to 10,000 serverside pages, all of thse use the same stylesheet. I have created a new serverside page which is like a dynamic menu system to help find specific pages from the existing 10,000 pages quickly and easily.
The problem is, that if the serverside pages are accessed the old way using the old menu system, they should retain their old stylesheet. however, if they are accessed via the new menu system, they should use a new refreshed stylesheet.

Interface And Graphics :: Resize Objects Dynamically In .net?
Oct 13, 2009I need to let the end user move and resize objects (like a textbox or button). There are several examples that demonstrate this in VB, but not in VB Express 2008, based upon VB.net.It looks like earlier you needed to access Windows API, but these calls does not work in VB.net. I understand that these call are replaced by "native" .net calls, but I cannot find any that does the job.
A typial example from old VB is:
Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long) As Long
This does not work in VB.net.

View 1 RepliesInterface And Graphics - Add Late Bind Control To Form Dynamically
Oct 14, 2010Using VB 2008. We have an app with a third party grid on it works well enough. This is a small utility within a bigger suite, and adding/updating it involves a simple EXE copy. The issue I am trying to address is that not all customers will have the 3rd party controls on their systems, and we want to avoid deploying them if we can.
Can I build the app so that if the controls are present, the app uses them. But if they are not present, I use a simpler control? I picture using a 'launcher' form that tries to load Form2 with 3rd party. if it errors, then just load Form3 with common controls. But can I even get to that point? With missing controls, will the app even load? I understand Late Binding for objects, but this is a control right on the form. Can I late bind a control and add it to form dynamically perhaps?

View 1 RepliesCreating A Byte() Dynamically?
Aug 6, 2009I am working on a simple windows app that will take our TripleDESCryptoServiceProvider Key and IV from a file and use it to Encrypt and Decrypt strings, etc...This works great and has for years in a utility program, but I want an easy app that can read the Key and IV...following format in the txt file:
[KEY] {123,123,123,123,132,132,123,...}
[IV] {23,23,23,23,23,...}
And then create the Encryption Pair...Currently I have the following
clientDESCryptoServiceProvider = New _
TripleDESCryptoServiceProvider
clientDESCryptoServiceProvider.Key = New Byte() {111, 222, 333,...}
clientDESCryptoServiceProvider.IV = New Byte() {1,2,3,...}
Is there any way to pull the {111,222,333,...} and {1,2,3,...} from a text file and create the Byte() that is required?I can read the info from the text file, but cannot seem to create the right format for generating the Byte()?

Jul 21, 2011We use a common web.config file to store all of our database connection strings.
I would like to have a way to read in all of them, somehow create a property or type so that they become dynamically available.
So when I want to create a new sql connection my my class can show the connections strings available.
Dim myconn as new MySqlOps.Connection(MySqlOps.ConnectionString)
so when the user types MySqlOps.ConnectionString. it will give a list of the connection strings read in from the config file.
Not sure how to approach making the connectionstrings available like above.
