View 5 RepliesSay I have a List(Of Tag) with Tag being an object. One member of Tag, Tag.Description, is a string, and I want to make a comma-separated concatenation of the Description members.Is there an easier way to do this than to read the Description members into a List(Of String) and then use the Join function?

View 39 RepliesI have a list of strings. For each string in that list, I want to prepend another string. I wrote a method to do it, but I was wondering if there was something already in .NET I could use to do this. It seems like something that could be built in, but I was not able to find anything.
Here is the method I wrote:
Private Function PrependToAllInList(ByRef inputList As List(Of String), ByRef prependString As String) As List(Of String)
Dim returnList As List(Of String) = New List(Of String)
For Each inputString As String In inputList
returnList.Add(String.Format("{0}{1}", prependString, inputString))

It works, but I would rather use built in functions whenever possible.
I'm migrating from VB6 to VB.NET, in hence my questions below:
I have to write a function that returns array of strings.
How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.
Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?
I have been looking for examples to find the string between two strings. This top one works fine;

Now the first one is fine - Ext_Volume is result of the string between the strings <Volume> and </Volume>. <Volume> and </Volume> are unique so this is straight forward.
However the second one - "^FDExp:" is unique, but "^FS" is not unique. There are occurances of "^FS" before and after "^FDExp:".
How do I get the string to search AFTER the occurrence, not before etc?

View 2 RepliesI have a DataGridView that has some columns with dates. It binds to an in-memory Datatable which gets loaded from an string array of data passed back from the backend Some of the rows returned have nulls for the date columns. Solution 1: If I define the Date column in the DataTable as "string" I can easily convert those nulls to empty strings and display it in the grid as empty strings (desired results). However, if the user clicks on the date column header to sort by date, it doesn't order the rows as you want. You get a purely string sort order. Not acceptable

Here's the weird problem I am trying to solve but cannot get my mind around it. In a text box 1, the user enters 2 or more strings separated by comma. then in text box 2, the user enter 1 or more strings separated by comma. The output then puts the strings from text box 2 between the strings in text box 1
Example:
TextBox1 = visual basic, java, perl

I have a function where I have to add two values (declared as string) on two different pages, So Iam bringing one value from one page to the second page where I have second value and adding both of them to display the result in a label. But I am not able to do that. eg: 1st value is 4.20 ( both values are time in seconds) and 2nd value is 0.34 then I want the result as 4.54( instead I am gettign the result as 4.24.0.34 , So can anyone tell me how to add these two ..My code is attached.
Dim L1 As String
L1 = main.TimeElapse(Value1).ToString
'Label1.Text value is the below line
Status.ShowSuccess("Ready: Result is " + _Myfunction.GetTimeInSeconds.ToString("N1") + TimeElapse(value1).GetTimeInSeconds.ToString("N2") + " seconds")
I am writing a program that uses an array with three columns and a varying amount of rows. I need to load info on a list of files in an archive(specifically: file name, size, path), and I am wondering what the most convenient way to store strings(to be loaded into the array) is.
For example: I tried creating a new .resx file in my project, and writing a function to be executed on form1_load that reads the strings from the .resx file and places them in the array in their correct column, but unfortunately had no success.
I really have no idea how resx files work, I can put strings in them using the resource editor, but I don't know how to retrieve them using resourcemanager.
I would just put the info straight into an array, but it's much easier to update a .resx file when the archive changes than it is to update the code.
Could someone please tell me how to use .resx files in vb.net? Or an easier way of accomplishing my goal?

I'm trying to create a number of strings based on one long string that i'm passing.
Basically this is an example of my long string
StrMain = AL123456 - PR123456 - RD123456 - LO123456
So in this case I want to create 4 separate strings.
Str1 = AL123456
Str2 = PR123456
Str3 = RD123456
Str4 = LO123456
But there isn't always that many or there may be more so I need to count how many - there are and with that then create the amount strings needed.
i need to be able to get the difference between two strings, i found out how to get the difference with this code:
Dim Changes As String = NewText.Replace(OldText, " ")
but i also need to be able to find the index of where the difference is, does anybody know how to do that ? EDIT:I just found a flaw in that code, if the OldText is "html" and the NewText is "html html" Changes is not gonna be "html"

Ok, so in an array of strings, I have stored 15 card picks. They are all two characters For example: [code] I do not know how to process the strings. For example a hand in Texas Hold Em' is a flush in which 5 cards are of the same suits (clubs, heart etc.) so I need to a way to find if picks(0) = 1h, picks(1) = 2h, picks(10)= 4h, picks(10) = 8h, picks(11)= 5h, picks(12) = 7h, picks(13) = 9h, picks(14)= 11s contain 5h's or not. In C++, I would have solved this problem by simply breaking down each string into two different parts and then counting the number of h's. Is this a good approach to use in VB or is there a simpler way to process strings?

I need to pass 2 strings from VB.NET to an OCX written for VB6. VS2008 put a wrapper on the OCX, but while the routine is called, the string parameters are not correctly received.
I do not know why but I am guessing that it is because, as I understand it, in VB6 parameters are passed By Ref as a default while in VB.NET, parameters are passed Bv Val as a default.
When I imported the OCX into VS 2008, it seems to have automatically defaulted the string parameters for the routine I need to By Val because the ocx export info did not specify anything.
Is there anyway to override VS 2008 so that I can pass the strings correctly to the OCX? Is there something else instead that I could do?
