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.

.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.

.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?

VS 2010 Reading / Cutting And Pasting Within One Excel Document.

May 22, 2011

Basically i work as a desktop support officer. our team does everything from fixing software errors on PCs in the office to moving them from one desk to another. When we do have to move anything though, it needs to be tracked so that our records can be accurate. To track where things have moved to, we have to:

1. fill out a form in an excel format and then fill out the same information into a text file format, and then attach both formats to the job record in our job listing system and send it to our hardware tracking team.

2. If an asset is being taken away to storage, but is considered to be too old, it needs to have an excel table filled out to create a 'disposal' label, or it can create a 'redeploy' label if it still has some years left in it.

3. If we are putting out a brand new asset, it needs to be updated on our tracking sheet to show that the asset is no longer in our storage as brand new.

This obviously creates a lot of administration work for our staff, so i have built my program to take all the information required once, and then split it off to the forms and labels as required.The part I'm stuck at is number 3. I have been working with the excel files in the following format:[code]What i need to do is as the title suggests, search an excel work book (the user will point to it) for the Asset Number in a particular sheet. Once it finds the asset number, cut the entire line out of the sheet and paste it into a different worksheet at the next empty line with a few edited values.

Extract String From String When Only Beginning Of String?

Basically I have a webresponse stream:dim lol as string = readstream.tostring there is a lot of information within the string but only one link starting with http: located near the end of the string - however there is no constant character point where I can start... (i.e. 38)

I want to extract the link from the string i.e. dog cat plane car [URL]..that is approximately how it looks above - words and url substituted I want to just extract [URL]..I had an idea of parsing the string from http: to the end Then after that splitting the string up again to remove the }], however it does not return anything

Asp.net - Decimal.parse Fails For Currency String Created With String.Format?

I have a field that I display via: String.Format({0:c},amount) This produces the string "$28.28" However, when I try to convert back to a decimal amount, I get an incorrect format exception: amount = Decimal.Parse(amount.Text, NumberStyles.Currency) I also tried it with NumberStyles.AllowCurrencySymbol with the same results. I verified that the value in amount.Text is "$28.28". Am I missing something? Shouldn't these two operations use the same currency symbol and formats?

Reference To The String In The Heap Is Passed Even When You Pass The String ByVal To A Method?

So strings are reference types right? My understanding is a reference to the string in the heap is passed even when you pass the string ByVal to a method.

String myTestValue = "NotModified";

System.Diagnostics.Debug.Write(myTestValue); /* myTestValue = "NotModified" WTF? *[code].....

And what is going on under the hood? I would have bet my life that the value would have changed....
