I must admit it's been a few years since my RegEx class and since then, I have done little with them. So I turn to the brain power of SO. . . I have an Excel spreadsheet (2007) with some data. I want to search one of the columns for a pattern (here's the RegEx part). When I find a match I want to copy a portion of the found match to another column in the same row.

i have a string array that i want to output to a text file. the array size is 10000. i fill the array starting from 0 with some strings. at the end, i only want to show the array from index 256 to the last array that is not empty (for eg. if the array is filled with data from 0 to 2000, i only want the text file to show the data from 256 to 2000 and ignore the remaining strings). Is there any function to do this?t i use is shown below

I have a string. I need to check what characters it contains because certain invalid characters are causing my sql query not to work. In the query I select where SupplierName is equal to the string. I need to replace the invalid characters at database and vb level. But I need to know first what the characters are.

Downloadsname=Downloads
downloadspath=C:documents and settingsJamesDesktop
how can I make it so that when they push a button it seraches for downloadsname then after the = is the text to use as a string and do the same with downloadspath
Well I basically know how to read a text file, replace text then write to one. how to append text after a specified string (ie, insert text at a specified line, removing the text after a string in a line and changing it without altering other lines, etc). Can someone please tell me how I would go about adding a string after a certain string in a text file? For example:
I Have:

I have a somewhat unique problem that I have looked for an answer to and continually hit brick walls. The problem is this. I'm using vb.net to read a byte array from memory which total 32768 in length, which is converted to a string. The memory is the active console chunk in the game Call of Duty 4.

I have built a DataTable from my database. Then I am looping through the rows and trying to access a string, however the value is being returned as each character in the string.

The Trap_Code values are two or three letter strings, the returned value is each letter once at a time. The loop seems to cycle through the individual characters of the string as an array rather than display the entire value, which is what I was hoping for.
is instr used in vb.net for this?
View 3 RepliesMy 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?
I have a strange problem where CInt (as well as Convert.ToInt32 or even Val) return -1 for a string "500". Using Gurock's SmartInspect for logging, I've checked all values at runtime (SiAuto... logs something, I'm posting the log below the code).

I have the following value 48.81, it comes as a string from the database, I need to convert it to decimal, I'm using:
Dim Seconds As Decimal = Convert.ToDecimal((Coordinate.Substring(4, 5)), CultureInfo.InvariantCulture)
I'm receiving 4881D and I need 48,81
I thought CultureInfo.InvariantCulture was going to help me with that
EDIT:The coordinate value is 675900.244.I'm "spliting" it like this:
Dim Degress As Integer = Coordinate.Substring(0, 2),
Dim Minutes As Integer = Coordinate.Substring(2, 2),
Dim Seconds As Decimal = Convert.ToDecimal((Coordinate.Substring(4, 5)), CultureInfo.InvariantCulture),
[code]....
This is the value of the coordinate in the database?
I am using Virtual Basic with ASP.NET in Visual Studio 2008. I am using Webmethod to communicate from/to the server with the client. Data can be queried and returned in small amount, but when I try get a relatively large amount of data, it's returning me a Server 500 error. My data is 226561 character long, so it's not that large, but it's relatively larger than my other working testing set, which are about 10k character long.
JavaScript:
PageMethods.my_func("context", success);
function success(result, userContext, methodName) {

Is there anything I can change to increase WebMethod returned string length limit? Is there even a length limit or is it some other problem I could not see?
I have created a function which essentially enables me to output anything I need from my database in a similar method to Facebook's FQL querying method as a JSON text result. I can also use the same function to get the output as a Dictionary, or List of(Dictionary) to use with VB functions for other purposes.

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.
View 3 RepliesI 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?

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.

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).
I made a Windows service which daily deletes some records from a SQL Server database. But i don't know what my connectionstring should look like ... the service and the database will both be located on the server.I found this example, which parts do i need to change ?

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
<laugh:894u8438:4434:words>
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.
