Using Access 2003 and VB code, I have created a form with a number of labels. The labels will display an employee's names. I have named the labels name1, name2, name3...etc. Using an ADO data set and DCount I have determined the number of names in an Access table (the number of names can vary). What I want to do is for each record in succession to pick the first name and surname from the data set , combine them into a full name (this part has been successful), and then set the full name into the label caption in succession. Example: full name 1 into name1, full name 2 into name2, full name 3 into name3... until all names appear as labels on the form.
I created a counter to and a variable to increment the label number but when I address the caption property of the variable containing the new label (e.g. name1, name2..etc.) it throws an errer at runtime. Here is the code:

I'm trying switch from using arraylist to arrays. Seams like arrays are not as easy to use when you don't know the size of the array.
Is it possible to use an array without having to specify the size of the array like in this example?

I have a piece of code written in Visual Basic:
Dim n As Double, i As Integer
n = 4
Dim Ramp_length(1 To 4) As Double
For i = 1 To n
Ramp_length(i) = Cells(13 + i, 5)
'Cells(65 + i, 7) = Ramp_length(i)'
Next i
Is there a way I can reproduce the result without declaring the array with a "fixed" length? I eventually want the code to read off a column of data with unknown length and store it in an array of equal or smaller length so it can be altered.
I need to seperate a name into 2 parts using split the first part being 2 letters "That was easy" but the last part of the name would have an unknown lenght. so how do I get the unknown length? I believe I understand the Join Part here is what I have but it only works when you know the lenght of the name
Project Notes
'Form has two textboxes and one button
'first text box holds a first and last name
' 1-seperate the first and last name into 2 variables

I have a question how can I save in My.Settings only the font name and not the size.I have a form where I can change the font for a label on another form. This works perfect.I can even save it in my.settings.
The thing is though, that on that other form I have 2 labels, thet should have the same font name, but the size should be different. (label1 has font size = 40 (can be changed) and label2 should have a fixed font size (should not be changed)).I tried to use label2.font.size = "14", but font.size is readonly.

What is the maximum size of a multidimensional array in VB.NET (in my case two-dimensional)? I'm using Visual Studio 2008, Framework 3.5 I found in msdn [URL]: "The length of every dimension of an array is limited to the maximum value of a Long data type, which is (2 ^ 64) - 1. The total size limit of an array varies, based on your operating system and how much memory is available. Using an array that exceeds the amount of RAM available on your system is slower because the data must be read from and written to disk." However, I am trying to use an array of data type single, with dimensions 64513 by 301 but Visual Studio seems to freeze when I execute the line to redimension the array ( Redim myArray(64513, 301) ). I have 4Gb of RAM and am using Windows XP (32-bit).
View 5 RepliesMy app is receiving data in blocks but I don't know what size data will be received until it is finished, unlike file reading. So my app loads the data in chunks of 1024 bytes and then stops when there is no data to read. My question is, is it possible to keep increasing the size of a byte array as the data is being received?
View 2 RepliesI want to write an extension method that works with all kinds of arrays (Integer, String, Decimal, ...). It returns an array of the same type and size as the input parameter array.[code]...
View 1 RepliesWhen you use array.length you get the size of the array and not the number of items in it.
For example:
Dim MyArray(10) as String
MyArray(0) = "Potato's"
MyArray(1) = "with"
MyArray(2) = "salt!"
MyArray.Length will return 11

I'm trying to find the sum of all the digits that make up the number 2^1000, which you may have guessed is from Project Eula. I think it's good so far except I'm just learning about arrays and dynamic arrays, so how will I know what the size of the index will be so I can specify when the Do loop should stop so I don't get an indexoutofrange exception?

Dim BigNumber As Double = 2 ^ 1000
Dim DigitArray() As Char = BigNumber.ToString.ToCharArray
Dim Index As Integer = 0
Dim SumOfDigits As Integer = 0

View 8 RepliesIs it possible to have a UD Class that can limit how big it can grow as an array?
for example:dim var(10) as class this would throw an exception cause the class will only grow up to 5 elements.dim var(4) as class valid cause it is under the 5 element rule dim var(4, 10) as class invalid cause the 2nd dimension is above the 5 element rule. (would throw exception)

I have to fix this by making a variable with type made by Structure bullet and then redimming it, i.e

This means for every variable with the bullet type i create i have to redim. Is there a way i can set the size of .mesh with .capacity for every single variable created with the bullet type automatically?
I am upgrading a project from VB6 to VB.NET. Unfortunately, I cannot include the DLL or even the name of the DLL that I am using here, I am under a confidentiality agreement. However, I hope I can post enough info here to get this frustrating problem solved.
In VB.net: Code:
So, if I run it as such, it errors out while calling SetParameters saying
The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))
If I comment out the line m_Parameters.SProperties = New S_Properties(9) {...}, then it does not error out, however the function returns 0, which means it did not actually set the parameters to the device. Trying to ReDim SParameters(9) will also give the hresult error. Doing it with my example above, I put a watch on m_Parameters in both VB6 and VB.net and they look IDENTICAL. All data is the same. Why would I get this ArgumentException in VB.NET and not in VB6 when I am passing in the exact same arguments as in VB6?
I'm attempting to get the size of a bunch of files located in a directory with an array. Using a single file, it works great. But as an array, I get an error. This is the code I was using:
VB .NET
Dim filepath() As String = Directory.GetFiles("C:Test", "*", SearchOption.AllDirectories)
Dim lvi As New ListViewItem
Dim fi As New FileInfo(filepath.ToString)
[code]....
It works... kind of. It adds each file to the ListView, when I just want the whole sum. I was hoping I could just use "DirectoryInfo" from the System.IO namespace, but everything I've been reading says I need to loop through the files.
I'm using extension methods based on an array and I would like to know if there is an easy way to check that array got a specify size instead of me doing a copy paste of
if array.count != 1000
throw new exception "size of the array does not match"

this a small sample of extensions that I use, I got WAY more
