If I dim an array to say, 5 elements, should it not fail if I go to add a 6th? I thought this used to require a redim. In .NET 2.0, I have a character array of length = 3. When I populate it from the db, one record had 4 characters in it and it successfully added all 4 characters to the array?

I don't know if I can do this here...but here goes. I want to generate a unique ID of fixed length The trouble is, the code example I found on the web is in C# (or C maybe) which I know nothing about. I tried a web-based C# to VB.net converter but the result doesn't work so its hard to understand what's going on (especially since I have not worked with bytes either this makes it more difficult).

I've a text file which has some data written. Records have Starting character as "#2" and Ending character as "#3" in ASCII respectively and the file includes series of records, but not written as Line by Line. The difficulty I'm having is, to how to transfer those data's into a database. The File comes a 7mb file and looping character by character then noting down the Record Starting Character and Record ending Character, and finally substring them is not feasible as it take more time and makes the computer slower. I would like to know is there any easy way to transfer them?

I'm parsing fixed length file with .NET 3.5 and Regex. This file is from bank. In customer name sometimes there is one characters from this set &,(),[],',"". These are characters, so far I've encountered. There can be anything else. Because of this my regex is failing. My regex is [A-Za-z0-9s-.,'""""(){}[]]{35}. Is there any wild card I can use for special chars rather than specifying individually. I also tried . but didn't work.

i am trying to import a fixed length text file into an access database (accdb). I already have the table created but it doesn't have to be that way. i am wondering if i know the field lengths, can i a use a SELECT INTO query to get the data into access. or do i need a schema file?

In my application, a string generated its length can varying from 1 to 100 (not using random number algo). But I want if length is less than 7 than need to add integers 1,2,3.. untill its size reach to 7. I implements it using while loop as :
If generatedUserName.Length < 7 Then
Dim count As Int32 = 0
While generatedUserName.Length < 7

Is any other better way such as enbuild function Tostring() with some parameter?

so i have a file that i need to read in vb.net. Each line is 32 chars long and each line consists of multiple fields. Meaning from char 1 to 9 it idicates ID then char 10 indicates an identifier,11-14 indicates a value field. I've looked at Readblock and it's not the tool for the job. Is there a way to break up each line into its respective fields other than just reading the whole line and breaking it up as a string?

Got a dll from a supplier that I need to call. His declaration is Declaration with Microsoft Visual Basic: [code]Now, the Sting * 20 is clearly not VB.NET, and sure enough it crashes when run - "Attempt to read or write in protected memory" and that leads me to think that there is something with that string definition - or possibly the I_Ref definition which hasn't been defined as fixed length.I've tried <VBFixedString(20)> when defining O_Err, but I have a feeling that it might not be enough when the function declaration is like that (not specifically fixed length). I cannot figure out how to specify this correctly.As a small hmmmm, the above is pasted directly from the suppliers documentation, but that't will never work, as there is a "," missing after I_Range as long... Clearly not something he has pasted from a working program.

what do you think would be the best way to load a fixed length text file into ms access? this is how i would normally do it if it was comma delimitted:
sql.CommandText = "SELECT * INTO [tblMailList] FROM [Text;DATABASE=" & FilePath & ";HDR=NO].[" & FileName & "]"
sql.ExecuteNonQuery()

I am using VB .Net to access the eBay API and store all completed orders in a database. This database is then fed into a proprietary shipping system, which can not handle an order number larger than 20 characters. eBay returns an order number like so 230407279314-680141236013 which is too long. The order number is always 12 numbers a hyphen and 12 more numbers. What I need to do, is turn this (the result can be alpha numerical) into a shorter, unique order key to store in my database alongside the true orderId (so that this can be referenced by the shipping software instead of the actual order number). The reason for the 20 character limit is the barcode algorithm used. Is there any way to achieve this in VB .Net 2010? This number can be anything unique, so long as it does not exist already (even a good uniqueid function would work, but I would have to query the database to make sure it isn't taken)

VS2010 (SP1) / .NET 4 on Windows XP. The question is simple, the answer; not so much. When generating a salt, should the LENGTH of the salt be random, fixed or a random number within a (min/max) range? I am using RNGCryptoServiceProvider to generate the salt, just unsure of the length of the salt.

I assumed it would be the same in VB2008 but I get the error.'cmbDataTable' is not a menber of 'System.Windows.Forms.Form'I am working my way through the project, first updating the global procedures - this is one - I haven't written the calls so cmbDataTable doesn't yet exist.

The file structure is fine for retrieving data from the file but when I go to write data to the elements and hit any of the fixed array elements, I get an exception error. this has got to be a sytax problem I am just not seeing.
It seems that I am not addressing the array member correctly yet the same logic pulls it properly from existing records on file.
in a Module I have the structure as follows:
Structure INVOICE
<VBFixedString(6)> Public NUM As String
<VBFixedString(2)> Public SYMBOL As String

I though I had solved this problem, but it is back:Code generation for property 'SelectedPeople' failed. Error was: 'Type 'ECS.Entities.Persistency.Person' in Assembly 'ECS, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable.'The property on the error message is a List(Of Person) and for some reason it trigger this error, for almost anything I do, and its getting really anoying.Okanswering to the answers here is a little more information about the problem.
Yes it is during design time, it happens bascially anytime a open a form that has a UserControl that contains the Selected property in it, sometimes it happens even if I don't have focus on the form, also if I try to compile/run it happens and the message come in the form of a Message Box with just a OK, ECS.Entities.Persistency.Person is just a LINQ to SQL Generated Class, this should not matter at all to the problem, although I have added the attribute before the posting.he reason that this happens is because the Designer attempts to put the property on the Property Panel, and for that to happen, serialization happens.tryed to hide the property from the designer by using this attributes.
<DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)> _
<Browsable(False)> _
Public Property SelectedPeople() As List(Of Person)
