Group, Spilt, Sort And Sum Up Values From A EDI String Into Variables?
Nov 15, 2010
I am new to VB.Net 2008. I have a tricky task to resolve, it is regarding extracting characters (values) from a long string, the extracted values from the text shall be summed up and sorted by keywords, reformatted and saved into a CSV file.

Last year (2010) I came across a FANTASTIC command that allowed me to take a string of variables with a common delimiter and break it all back out into separate variables (possibly an array) with one statement.
[Code]...
As long as the delimiter was a unique specifiable character, this one-statement command could break it out into elements. my memory and point me in the right direction.

I'm using a Listview in VirtualMode, so I can 'add' a lot of files almost instantly. A Listview in VirtualMode does not allow sorting, so I need to sort the data myself. The data is stored as a List of Structure (it's faster to load than a List of ListViewItem). The code below works fine, but I need to sort based on multiple variables in the Structure. Code:

Sub Sort()
ReDim RollsCC(NumOfPlayers - 1)
For N As Integer = 0 To (NumOfPlayers - 1)[code]....
Here I am creating a temp single dimensional array, merging my 2d array into it, and then attempting to sort it by Rolls(N,1), which is a integer 1-6, Everything seems to be working right with the exception of this.
RollsCC.Sort(RollsCC, 0, 1)
How would one specify a numeral sort based on the first character in the string? im aware that I am switching Rolls(n,1) and Rolls(n,0) information during the sort.

I have a table of questions and a table of alternatives corresponding to each question. I'm planning to build a questionnaire system (in ASP.NET) which select a few random questions from that total of questions.
I'm using the following SQL Statement to choose the random questions:
SELECT TOP (@maxQuestions) QuestionID, QuestionName FROM Questions WHERE CourseID = @CourseID ORDER BY NEWID()
Which populates a DataTable in a DataSet and data bind it to a Repeater control (the parent Repeater). What I need now is to get every alternative related only to the current random questions generated from the query above in a separate SQL Statement so that I can populate the DataSet with a new DataTable, add the relation between them two and data bind it to another Repeater control (the child repeater).
I don't know how to get only the alternatives related to the current random questions I generated.Otherwise, I get an error saying that I don't have all child values corresponding to the parent values and I can't group the alternatives inside the same question.

Im attempting to loop through all the text boxes inside of a group box, and add the text into a list box to later be written to a text file. Here is the code I am using.
Dim cControl As Control
Dim FILE_NAME As String = "Tester.efw"
Dim Group As GroupBox
[code]....
Now instead of locating only the text boxes, apparently it is still trying to identify the labels as text boxes, because I am getting this error:Unable to cast object of type 'System.Windows.Forms.Label' to type 'System.Windows.Forms.GroupBox'.

I have a List(of String()). I have written a custom comparer (implements IComparer(of string)) to do an alphanumeric sort.Is there a way to sort the List using a given index to determine which position in the String() to sort by? In other words one time I might sort by Index = 0 and another time by Index = 3. The length of all String() in the list is the same.For reference this question is similar to Sort List<String[]> except I am using VB.net and that question is hardwired to Index=0.
EDIT from OP's comments:I started simple with the non custom comparer but I am getting an error: expression does not produce a value. Not sure what I am doing wrong.Here is the code:
Public Shared Function SortListOfStringArray(ByVal ListOfStringArray As List(Of String()), ByVal SortByIndex As Integer) As List(Of String())
Return ListOfStringArray.Sort(Function(x, y) x(SortByIndex).CompareTo(y(SortByIndex)))
End Function

We have a generic List(Of Product) that must be sorted on two or more properties of the Product class.
The product class has the properties "Popular" numeric (asc), "Clicked" numeric (desc), "Name" string (asc). In order of naming the properties we want the list to sort.
How can it be sort with an lamba statement? If have found to sort the list based on one property.

So basically what I'm trying to do is write data from an XML file (a "save file") back into the form. My controls are in all different group boxes (makes it much easier for showing and hiding groups of controls dynamically). I thought about and am putting each control's Parent name into the file, but can't figure out how to get that parent name back into the DirectCast within a For...Next loop so it will actually cast the data into the control.

I�m using VB.Net 2008 application program.I�m using DataGridView, where column types DataGridViewTextBoxColumn. I have 3 fields. 1 field values are numeric, 1 field values are string and 1 field values are decimal.
When I try to sort the string value column, it sorts correctly. But when i try to sort the numeric value column, it sorts as if its string value.

I would I have a program that I use in the computer in my network, but for every user I need to edit the source to this user, thus the user cannot edit his information, just use the program how it was ... So, looking over the internet I found a "program" that may contains my solution... Its a Keylloger, I'm not meaning use this keylogger, no, but it has a a very interest feature: I use the main form to edit the information then after all it create a new program with the new information inside... I use my main program to create every userprofile then my program create a new program with the profile inside...

what if you created a pool of numbers: 1 - 21 and then chose a random selection from the pool? Something like the following:[code]This gets rid of those messy if statements and all of those loops.

i had a look at how to set values of variables from nummbers stored in external txt files the variables then needed to be added up so i used trial and error first
((XVAL) + (NEWVAL))
assuming that XVAL was set to 10 and NEWVAL was set to 20 i expected to get the answer of thirty but waqs presented with the new value of 10 20 VB.net pysicaly added the two values together but i wanted the mathematical product of the two which is ((10) + (20)) = 30

I have a VS 2008 C# application that I'm converting to VB 2008.
This statement in C# works as I expected:
IPAddress IPAddr = new IPAddress(0xFFFFFF0A);
IPAddr has a value of 10.255.255.255.
However, in VB this fails:
Dim IPAddr As New IPAddress(&HFFFFFF0A)
with invalid argument (the parameter of IPAddress should have type Long).This also fails:
Dim Addr as Long=&HFFFFFF0A
Dim IPAddr As New IPAddress(Addr)[code]....
does not produce a value of 4294967050, but -246. It appears to have defined a .net type of Int32, not Int64.How do I declare an Int64 variable in VB using a hex constant?

I have 3 variables. Lets call it "a", "b" and "c". These 3 variables can "independently" have 3 different values. Lets say: "1", "6" and "10". when you think of them as combination; there are (3^3) 27 combinations. I am told that it can be done through the recursive functions. However i am not a good developer to handle with that. Would u please help me?
- 3 variables and 3 different values are simplified. In fact; the numbers of variables and different values can vary.
- i know only the language, visual basic in .net; please don't answer in other coding languages.
additional note: i am going to put the these combinations in the string format into a collection.. for example "1;1;1", "1;6;1", "1;6;10".. and so on..

I have a list of variables that are being created on one line.
Dim strFirstname, strMiddleName, strLastName As String
Is it possible to set the values for all of them at once? I know this doesn't work, but this is what I'm trying to do :
Dim strFirstname, strMiddleName, strLastName As String = ""

I have a database in my app which loads and displays some information on a form by binding the Comboboxes and Textboxes. However, I need to get some of the other values from the database for calculations before they are displayed on the form and I can't seem to find out how to do this.I could bind a couple of Textboxes to the database and then use those values to calculate, but it doesn't seem like a very efficient way of doing things.The dataset is created using the wizard and the controls are linked in the UI.
Please bear with me, I'm still a noob.
