Declaring A Variable Length Array?

Dim sArrayList() As String
But when I do that in VB.NET, it highlights my array name and says "unused local variable". What do I need to do to get it to work without an error?

View 4 RepliesMarshal Variable Length Array?
Jun 8, 2010I'm trying to call the GetInterfaceInfo Windows API - it accepts a structure as one of its parameters and this structure has a member that is an array. The API populates the contents of the array when it is called and there can be any number of items in the array. How can I define such an array in my structure?
If I just use a normal .NET array like so then the program just crashes (no exception thrown)
<StructLayoutAttribute(LayoutKind.Sequential)> _
Public Structure IP_INTERFACE_INFO
Public NumAdapters As Integer
[Code]...
and this works fine, but the problem is I have to define the SizeConst attribute as you can see to something large (64 in this example) so that the API doesnt fail because the array wasnt big enough. Firstly this is a waste of memory as in most cases the number of items the API sticks in the array will be less than 10, but secondly if there was ever a case where the API wanted to put more than 64 items in then it would fail.
Using ReDim to set the length of the array at runtime seems to have no effect, and that SizeConst attribute has to be set to a constant value so there's no way I can dynamically set it.

VS 2005 - Length Of Array Is Integer Variable
Apr 26, 2009I have a problem when debugging a code. On top of class I declare an array, and the length of array is an integer variable which is applied value below declaration of array.
E.g. class declaration
Dim array1 (2, integer) as string
Public Sub
integer = 5
End Sub
So basically, array is created with integer being 0 or whatever, because it is declared before integer was assigned a value. But the problem is, I need it to be declared at class variable so I can use array in different subs.
VS 2010 Variable Length Rows In Table?
Dec 26, 2011I am wanting to create 2 tables called Stores and Locations. Locations is a table containing a unique location_code and a location. Stores is a table containing a unique store_code a store name and a variable number of location_code's and a relationship is set up between the 2 tables.
creating the Stores table in particular the location_ code. Can rows in a table have differing numbers of columns? as a particular store type could be in many diferent locations. I feel it should be possible to set up some sort of array of Location_code's in the Stores table.

Regex Replace All Characters In Variable Length String?
Oct 6, 2010Using VB or C#, I am getting a string of variable length from the database. This information is sensitive information that only certain users will be able to see.I have two cases that will use the same logic (I think).scenario 1: replace all characters with xscenario 2: replace all characters with x except the last 4 characters (assume length > 4 - this check is being done).I thought that this would be easiest using Regex.Replace(input, pattern, replacestring). As opposed to a lot of string handling with substrings and forcing a length of 'x's.
View 2 RepliesSocket.Receive Method - Increasing The Length Of Variable
Nov 28, 2009While using the Socket.Receive method to receive messages through network, you should define a variable as the buffer and you have to specify the length like this: Code: Dim _ReadBuffer As Byte() = New Byte(LENGTH) {} My question is: What is the bad thing about increasing the length of this variable even if the received messages are sometimes shorter? (i.e. if some body let it 10000).
View 1 RepliesInterface And Graphics :: Program Generated Variable Length Form?
May 10, 2011I have an existing vb.net application which uses a home grown database. The database has over 60,000 unique multi-field records in it.The user can search in each field using drill-down to find a record, and then can add that record to a separate database.(60,000 collectibles described in a master database. User can drill down by category, manufacturer, year produced, etc. to find a record and then add it to their own 'collection', 'wanted', 'have for sale', or 'spares' database for record keeping.)
Instead of having them drill down, I would like for them to be able to perform a search and have all of the results (any amount of matches from 1 to 60,000+) appear on a scrolling form with a checkbox next to each so that they can simply check any that they want and do a mass add to their list databases.
The part I cannot figure out is how to have vb.net (2008) create a variable length scrolling form with the results, and how to identify the checkboxes (generated by the system for search matches) to see which, if any, have been checked by the user.

Feb 17, 2011I have a VBA form in Microstation I am using to try and help automate a task. The only problem I am having is I am reading a textbox (Filebox.Text) and setting it as the variable (FN). It works, because I used Msg.Box (FN) to test it. However, in two of the lines of code, I am trying to use (FN) to pass the typed in filename to the command to run in Microstation. Unfortunently, it gets passed on as (FN).dgn instead of the actual filenale typed into the textbox. Is there a way I can make the variable actually seen as a variable?

Text Box Max Length Not Working Correctly?
Mar 16, 2010i have a text box that has a max length of 5. when typeing into that text box the character input stops on the 5th character. if i set teh text property to a sting that has more than 5 characters the text box accepts the string. in vb6 i think that the text box would truncate the string to 5 characters.
does anyone know of a way to truncate, or get the text box to only accept the maxlength of the text box
