VS 2005 Finding String Within String?

Mar 30, 2009

My problem seems simple but I can't find an answer for it.I need to be able to pull a phone number (string) from an entire string. example: "My phone number is (xxx) xxx-xxxx, call me as soon as possible."

Its obvious to me that the phone number should be able to change depending on who you are talking too. So the question becomes, how do i search for the phone number's format within the above string?

Finding Information In A String

Oct 12, 2009

I think VB has a way of doing this, but for the life of me I can't find it. I want to search through a string for anything contained between two certain characters, e.g between 2 | characters. I'm not sure if I want to split the string at this point, but I only want anything contained between the two | markers. So for example if the string reads |ABC|DEF I only want to retrieve the ABC, but not the DEF as it's not completed yet.

Finding Spaces In A String

Feb 14, 2009

I want to be able to find both spaces using the indexof method. Here's my code so far. Basically the program will turn the string "Will Smith" to "Smith, Will" But I noticed when I type in a name with a middle initial or middle name "Will J Smith" I would get "J Smith, Will" And I want to be able to find that second space when its there and apply a code that would produce "Smith, Will J" When there is a second space. How would I go about doing so?

Finding The Greatest Value In A String?

Nov 17, 2009

Ive got a question about finding the greatest value in a string. I am connected to a database but I am positive that part is right. So i posted here instead of there.

Dim x As Double
Dim ConnStr As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=DBASE.MDB"


How do I make my If..Then statement return the highest value of row 0's x? My output (by changing the if then statement) will either return the first or last entry in row 0. I hooked up my code to a list box and got all the data to list perfectly i just don't know how to get the highest number after i use the formula for x (which is {c1-c2}/c2).

Finding Words Within A String?

Mar 31, 2011

Basically what I'm trying to achieve is to extract all the words within a piece of string and transfer that from one text box to another text box.

An example piece of the string would be


However the words within the string will never remain constant and the characters before and after will change. Is there anything that will read the string and take a word from the string without it being pre-programmed. The string it is reading from is uploaded from a text file.

Approach On Finding Next Word In A String?

Apr 2, 2009

any other approach on finding next word in a string. What im trying solve is this.

Lets say this is the whole paragraph.

Hello visual basic
Hello visual basic
Hello visual basic
Hello visual basic
Hello visual basic
Hello visual basic

now i search for the word basic.if i press the button find. the first "basic must highlighted, and then if i press again the button the next "basic" is the highlighted one and so on.I already finsih that scenario. What i've done is that first im going to search all the positions of the word and then store it in a array. Then after the array populated with different location of the word that is searching. that is the time i call all the indexes of the array one by one. But i don't want my approach because imagine i have 10000 words. and i search for a word or letter. Lets say the result is 5000 match. so it needs my array to be size in 5000. what a mess in memory.

I don't want to used the FinsString or Find function of VB i want some algorithm to do this. Anyone have a easy approach..

C# - Finding A Repeating Pattern In A Given String?

Jan 4, 2012

I have a networkstream (using C#/VB.NET). while on reading values coming like this:

&% 68 kg K A&% 23 kg K A&% 174 kg K A &% 68 kg
&% 34 kg K A&% 2334 kg K A&% 68 kg K A &% 68 kg K A
&% 2348 kg K A&% 78 kg K A&% 28 kg K A&% 68 kg

The numerical(weight) value will be continuously varying.

Every time i am reading the starting of the stream differs. But the pattern remains the same. How to split that into '&% 78 kg K A' which represents one set.

How to extract the weight value from this stream using Regex or any other methods?

C# - Finding The Index Of Characters In A String?

Oct 22, 2010

I have a text file that is automatically generated by an older computer system daily. Unfortunately, the columns in this file are not delimited and they are not exactly fixed width (each day the width of each column could change depending on the amount of chars of the data in each column). The file does have column headings, so I want to find the width of each column using the column headings. Here is an example of the column heading row:

JOB_NO[variable amount of white space chars]FILE_NAME[variable amount of ws chars]PROJECT_CODE[variable amount of ws chars][carriage return]

What I want to do is get the index of of the first char in a column and the index of the last white space of a column (from the column heading). I would want to get the index of the "J" in JOB_NUM and the last white space before the "F" in FILE_NAME for the first column.I guess I should also mention that the columns may not always be in the same order from day to day but they will have the same header names. I know I can use the string.indexOf("JOB_NO") to get the index of the start of the column, but how do I get the index of the last white space in each column? (or last whitespace before the next first non-whitespace that denotes the start of the next column)

Finding Pattern Without String Array?

Nov 14, 2011

Im trying to make an on access file scanner, YES I know that C++ is better, but this is a concept of thought, trying to challenge myself to see if its possible in vb.

Anyways, I have a list of Hex definitions, my question is, how can I index this list so I can access the definitions faster. A definition looks like this:


The part after the equals sign is the HEX signature, while the first part is the name of the definition.

Basically what I am trying to do is index them somehow where I can scan faster, as I have over 60,000 definitions and I have to split each individual one in order to get the signature name. It takes about 45 seconds or so to scan a 500KB file. I need it to be WAY faster.

That can be also something like this: {a|b|c|s|f|f|ft|r} or any number of items inside but at least 2 items so the pipe symbol is another key. Is this an easy regular expression? I'm using 2005.
