Jun 25, 2012

Cutting Up A String?

Jan 27, 2010

Builting a calculator. I have a string of two numbers separated by an math sign. Knowing the length of the first number then adding one for the sign will produce the start length of the second number. Trim the original string to get what I need.

dim num(25) as double
dim length,length1 as integer
dim string, string1 as string
length = Len(num(n - 1))
length1 = length + 1

Cutting A String Without Half-words?

Aug 8, 2003

I need to display the first c.200 characters of a longer string, for the homepage of a news website. I am using VB.NET. Obviously, cutting exactly 200 chars quite often cuts a word in half, e.g.: "The last five years have seen a radical increase in the volume and complexity of company legislation. The Bahamas has established a Stock Exchange, passed legislation aimed at regu" I need a function that will produce: "The last five years have seen a radical increase in the volume and complexity of company legislation. The Bahamas has established a Stock Exchange, passed legislation aimed at" I can then add "... [More]" or whatever to the end of this string and voila! Is there any way of using regular expressions (regex), substr or something similar to produce this output?

Parse A String To Specified Length (without Cutting Words)?

Jun 24, 2009

I have a long string that I need to parse into an array of strings that do not exceed 40 characters in length. The tricky part of this for me is making sure that the regex finds the last whitespace before 40 characters to make a clean break between strings since I don't want words cut off.

Prepend A String To All Strings In A List Of Strings?

Aug 5, 2010

I 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))

[code].....

It works, but I would rather use built in functions whenever possible.

.net - Cutting Off The 0's At The Front Of A Record?

Feb 6, 2012

Basically, I have an Access database with Primary keys that are structured with this format ("02"000).When I try to paste the number, it ignores the "02" and goes straight to 000.For example, here is the code;

PeriodRoomID.Name = ("R" & ds.Tables("sqlSpecRoomRequest").Rows(i).Item(1))

What PeriodRoomID.Name should be is R02001.What PeriodRoomID.Name comes up as is R1.It ignores the "02" and ignores the 0s. This makes sense mathematically but it is not what I want. I need a way to get the exact output and not some simplified version.

The query;

SELECT SpecialSoftware.SpecSoftID, SpecialSoftware.RoomID, SpecialSoftwareNames.Description, Rooms.Capacity
FROM SpecialSoftware, SpecialSoftwareNames, Rooms

Cutting Off Digits And Rounding Up/down?

Jul 22, 2010

I need a function that takes a decimal, with a certain number of digits behiond the comma and convert it to a string with a different number of n digits behind the comma. (to display it)My problem is the rounding ip/down.

like 123,789 with n = 2 --> 123,79
or 123,4 with n = 0 --> 123
or 123,5 with n = 0 --> 124

I did not find an existing function that does that, so I wrote one myself.However the code has become soo complex and it still does not work well, and I get frustrated to spend soo much time with something so trivial.Does anyone know a function that can do this? There must be something out there.

Find Strings In A String?

Mar 11, 2011

I have a string, and I want to search it for multiple strings, which I basically want to use for searching for urls in an HTML file that's been loaded into a string.

so get the value of everything between

href="http:// and the next " and return it (I want to check each one separately and do different things with them, so maybe add them to an array that I can loop through?)

preferably simple short code than highly functioning code

.net - Cutting Up Large XML File Into Small Chunks?

Jan 30, 2011

I have a large wikipedia dump that I want to cut into different files (1 file for each article). I wrote a VB App to do it for me, but it was quite slow and crapped out after a few hours of cutting. Im currently splitting the file into smaller 50mb chunks using another app but thats taking a long time (20-30 minutes for each chunk). I should be able to cut each of these up individually if I do this.

Does anyone have any suggestions of a way to cut this file up quicker?

C# - What Are The Different Methods For Injecting Cross-cutting Concerns

Nov 10, 2009

What are the different methods for injecting cross-cutting concerns into a class so that I can minimize the coupling of the classes involved while keeping the code testable (TDD or otherwise)?

For example, consider if I have a class that requires both logging functionality and centralized exception management. Should I use DIP and inject both required concerns via an interface into the class that requires them? Should I use a service locater that I pass to each class that will require some cross cutting functionality? Is there a different solution altogether? Am I asking the wrong question entirely?

Interface And Graphics :: Cutting Text From RichTextBox?

Feb 15, 2011

I want my Richtext box to be populated with a text string that contains HTML-style tags to set colour, underline etc.When I try to remove the tags using .cut(), the first cut always works, the second cut only sometimes.Here's a sample to test it:Create a new project and add a button and a richtext box.Add the following code:

Code:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim testString As String = "ABC<R>DEF</R>GHIJKL"

[code]....

This code works fine.The text between the tags is turned red, then the tags are removed.Now rem out the msgbox line and run again.Sometimes it works, sometimes the second cut fails with no message or warning.I am using Visual Basic 2010

Visual Studio 2010 v 10.0.30319.1
.NET framework v 4.0.30319

Variables 'hiding' When Cutting And Pasting A Groupbox?

Mar 29, 2011

I'm working with the graphic designer in Visual Basic 2008 Express Edition. I tried to cut and paste a groupbox and the variables reverted to standard ones (CheckBox123 etc.), and when I tried to change them back to their proper names, I got an error message stating that this name is "already in use by another component". But this is nowhere to be seen anywhere in the "Form1.vb[Design]". How do I either get rid of these "hidden" variable names or reunite them with the groupbox they used to belong to?

Choose The Same Strings From Two List (Of String)?

Feb 24, 2012

I have two List(Of String).Both Lists contain duplicate strings. I want to pick out all the strings which are contained in both the Lists. For example:

List1 ={"10X100","10X100","10X100","50X100","50X100","100X100"}
List2 ={"10X100","10X100","20X100","50X100","50X100","100X100","200X100"}

So, the result should be: List3={"10X100","10X100","50X100","50X100","100X100"}.How to do this?
