I have a string containing many lines. Each line has many values separated by commas. Basically it's in CSV format. The number of lines is variable but the number of columns is always 7.
I can get each line into a one dimensional array using Split(Var, Chr(10)).
I'd like to make it a two dimensional array where the second dimension contains each comma separated value.
I've got
Dim VarArray1() As String = Split(VarText, Chr(10))
Dim VaryArray2(0 To VarArray1.Length - 1, 0 To 6) As String
Is there a quick way to get the contents of VarArray1 into VarArray2. I know I can do the following.
For Counter = 0 to VarArray1.Length - 1
Dim line as string = VarArray1(Counter)
Dim Values() as string = Split(line, ",")
For Counter2 = 0 to 6
VarArray2(Counter,Counter2) = Values(Counter2)
Next Counter2
Next Counter
But is there a quicker way to do it that doesn't require passing through each element of VarArray1 and then passing through each element of Values.
The eventual goal in all of this will be to find the highest value in the 3rd column (the arrays are strings at this point because not all columns are numeric). To do that once I get the values into VarArray2 I suspect I have to pass through each element VarArray2, i.e. VarArray2(Counter,2). Unless I can copy the whole third column into a SortedList?

I'm working on a home project using DirectShow.Net. to learn some VB.net. Most of the examples I've found have all been in C# so I'm looking through code for ideas and converting where I need to. I keep stumbling upon these declarations and I'm unsure how to convert it to a VB.Net statement.[code]Then the second part seems to be assigning the value but as its made up of two parts im unsure how that works?
View 2 RepliesI am having a problem understanding the following error message:
Value of type 1-dimensional array of string cannont be converted to 2-dimensional array of string because the array types have different numbers of dimensions This line seems to be causing the error:

Question: How to shorten this array creation ? I need to create an array of type ReportingService2005_WebService.Property with one property.

For some reason when i declare an array and set it to a certain amount of elements then under it specify the elements it works in VB 2005 but when i do it in VB 2008 it get : "declaration expected " and i get words underlined.

Dim words(20) As String
words(1)="Computer"

View 7 RepliesThis is hopefully a softball syntax question: I need to call a method with an empty Object array for evaluation and set initial state. In C# I would just do this:
func(new Object[]{});
In VB.NET I am forced to do this:
Dim ctrls() As Control = {}
func(ctrls)
Is there a way to shorthand the call in VB.NET and have everything happen in one line of code?

View 2 RepliesI have been working on an activeX control which works on serial port communication. Now I have completed the project and created its setup.exe using Visual studio 6 -> Tools -> Package and Deployment Wizard. Then I installed the control in another PC and in a new project included the control using project -> components. But when I click on the control in the toolbox and then include on the form it gives the following error : delete current link ? and on clicking OK, nothing happens. I tried searching a lot on google but didnt find anything. Another problem is that I have created a string array as a global array which can be accessed by all the methods.I am able to include the same activex control in my own pc when I have created the project. Here it works fine, I am able to access all the methods that I coded in the control, but the String array mentioned above can be accessed in other project. I tried writing Public before the array declaration but it give me the compile error : "Constants. fixed length strings, arrays, user defined types and Declare statements not allowed as Public members of object module."

i'm extremely confused. my professor gave us this as the FIRST problem to do in this intro to VB class...on page 380 of our text. it is due today and i have been up all night trying to figure out where to even start. i'm so frustrated. could someone please help me and steer me in the right direction? use a one dimensional array to solve the following problem: a company pays its salespeople on a commission basis. the sales people receive $200/week, plus 9% of their gross sales for that week. for example, a salesperson who grosses $5,000 in sales in a week receives $200 plus 9% of $5,000, a total of $650. write an application (using an array of counters) that determines how many of the salespeople earned salaries in each of the following ranges (assuming that each salesperson's salary is truncated to an integer amount): $200-299, $300-399, $400-499, $500-599, $600-699, $700-799, $800-899, $900-999 and over $999.
Allow the user to eanter the sales for each employee in a TextBox. The user clicks the Calculate Button to calculate the person's salary. when the user is done entering this information, clicking the Show Totals Button displays how many of the salespeople earned salaries in each of the above ranges.
I'm having trouble with this specific code and on arrays in general. This is what I am asked to do: "In this exercise, code an application that displays the number of students earning a specific score. Declare a 20-element, one-dimensional integer array named intScores with the following 20 numbers assigned to the array: (88, 72, 99, 20, 66, 95, 99, 100, 72, 88, 78, 45, 57, 89, 85, 78, 75, 88, 72, and 88). Code the procedure so that the user can enter a score from 0 to 100. Then the procedure should display using a message box the number of students who've earned that score."
First off, I do not know what I'm doing wrong with my array.. it says there's an error in line 31 saying "variable intSubscript hides a variable in an enclosing block" but I don't know what that means. And lastly, once that is sorted out, I don't know how to code a message box to appear saying how many students have received that score.
