I have many strings in a two column text file. The first column is the start position, the second one is the string.
[Code]...
The second column contains 100 chars.Obviously these strings have overlapped, if a start position is given and the string length is given. How to merge them together? Ex, I want start point is 38781735, end point is 38781900. The string length is 38781900-38781735+1
i have 2 string arrays and I want to merge them together then put the elements into a third string array ..
for an example :
string1="a","b","c"
string2="d","e","f"
after merging:
string3="a","b","c","d","e","f"
Say 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 2 RepliesI am working on a UDP Client/Server, and currently i have them sending back and forth strings, which i convert to bytes, and then open the bytes to read. I want to now send an Object instead of those strings, which includes multiple unsigned integers and strings.
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;

Using reader = New StreamReader(filename)

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?
Dim str As String

Is there an easy way to find a certain string within a string and then return the strings that you find as an array?I have written this:

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

I modified a program in Expressions Blend that is C# I want to use this program as part of a VB program that I am creating. Is it possible to create a VS 2008 application using mixed languages? If not I can build the C# app to an Executable, but then how do I get it to run from within my VB app?
View 8 RepliesI have an application, written in C#, which needs some functionality from VB.NET (better said, something valid in CIL but not provided in C#).
So I have an executable and a library file.
Problem:
It has to be published in one file and may not be split to different assemblies!
But:
It's a WPF application, ILMerge will not work.
What could I do?Is it possible to generate (performant) IL on the fly?
I'm trying to create a program that will merge two data tables (one from a database on a network drive, the other is found in a database on the local machine). Each datatable is identical in structure, only (maybe) differs in content. The structure has a primary key, dateCreated, and dateLastEdited fields (plus other fields). I would like to merge down from the network to the local database. If the primary key does not exist on the local db but does on the network, copy from the network db to the local table. If it does exist, check the dateLastEdited column and copy the latest row to the local table.
How would i set up the code to do this? Any assistance would be great.
I'm trying to merge 2 files - a 'simple' string replace. 2 files - an ini-style data file that has <descriptor>=<value> with about 70 rows created by web-form and database, and a csv template file with 2500 rows that has 12 fields, but the values will either be in fields (4) and (5) OR (6) and (7). The data fields won't always be in the same order. I'm reading a line from the Template file, then looping through the data file looking for a descriptor match then replacing it with the value, but because they are in pairs per line, I have to loop twice; then loop to the next template file and so on. Then cleanup to remove the unused descriptors.
I have been unable to crack this for about a week. I wrote a VBScript version yesterday in about an hour and it worked flawlessly first time taking 2 seconds to produce the csv output file exactly as required.
Tried reading the data file and looping through the template, tried almost every combination of Using/End using; For/next, Do Until, Do while, etc. Used Streamreader, File.ReadAllLines, I've read msdn till I know it by heart, but no use. You name it, I've tried it. Must have missed something or it would work though.
You are my final hope. The problem part of the code is below...

View 1 RepliesI have a GUI that is running for a form, let's call it Class xWindow. It has finished processing data and is simply waiting for the user to press a button, i.e. the main thread has nothing to do. Just before it finished processing, it kicked started something that has a callback function which occurs in a new thread (e.g. a system timer or a Bonjour callback to say that a service has been found on a port). This callback occurs within the xWindow class.

I need to marge two datatable with condition. i table data come from local XML Database and another data come from remote sql data if any update made at remote datatable and then marge with local datatable. i wrote a code below :
Public Sub MargeTwoTable()
Dim SQL As String = ""
Dim RemoteTable As New DataTable
Dim LocalTable As DataTable
[code]....
as you see in my code data come from remote database which update date getter then local database . Both table are same and "ID" is primary key. I code is working well. But problem is that when data more then 1000 updated record so this function take too long in loops.
i write a code like : Dim mm() As DataRow = LocalTable.Select("ID = '" & RemoteTable.Rows(i).Item("ID") & "'"). for finding local datatable id row so when data is more then 1000 it take too long because localtable record more than 100000 records. So I need someone help to modify my code what the best way to write the code.
I need to marge two datatables with condition. I have a datatable where the data comes from a local XML Database and another datatable where the data comes from a remote SQL Server. If any update made in the remote datatable I need to update/merge with the local datatable. Here is what I have so far:
Public Sub MargeTwoTable()
Dim SQL As String = ""
Dim RemoteTable As New DataTable
Dim LocalTable As DataTable
[code]....
In this code data comes from the remote database which updates a date getter then the local database . Both tables have "ID" as the primary key. The code is working well, but the problem is that when more than 1000 records are updated this function takes too long using loops.
