I have a string that has 2 sections broken up by a -. When I pass this value to my new page I just want the first section. An example value would be: MS 25 - 25 I just want to show: MS 25 I am looking at IndexOf() and SubString() but I can't find how to get the start of the string and drop the end.

The error is Value of type '1-dimensional array of string' cannot be converted to 'String'.
I want the Function to accept List(Of String), Array & String and similarly return List(Of String), Array & String respectively. The Function simply adds a string (month) to the input collection. I just want to use it for string, array and list with needing to think of conversions.

I'm sure but can't see the answer. Currently going through a string "DO While Not ts_IN.AtEndOfStream" looking for information. This includes then checking another string (while inside the first) for matching reference point for further data.
So within the first loop, I have a second loop "Do While Not ts_IN2.AtEndOfStream". And looping through that string searching for the reference point.
This works initially, but after awhile don't find anything because it is not going back to the start of ts_IN2 string each time loops on the first section.
How can i write a " and it not gets it like a string end/start? Example: Dim test as String = """ MsgBox(test) and that msgbox would display a ".

View 4 RepliesThis code should read the string "34,56,23,74,69" from a process's memory addresses (in this case notepad), right now it works but very slow and I think it even breaks somewhere. My problem is with the ReadProcessMemory function. I can't make it read an entire mbi.RegionSize into the buffer. I tried everything and now, it only reads 1 byte at a time until the mbi.RegionSize is finished then it checks if the text that was read contains the text I need to be found, then it goes to the next mbi.RegionSize. Now, even with notepad which is very small it still takes 10 seconds to find something and I intend to use it with a much bigger program, so it will take like forever. Another problem is that it only finds the string "34". If I put "34,5" it won't work.

I'm new to these forums but am really enjoying reading the various posts. I have a question regarding string to date converting. I have the following string from a file I need to convert to a valid DATE in VB, but I am unable to with the attempt's I have tried. The date is: "Thu Dec 13 10:00:06 2007" So I am assuming it is something like this in VB: "ddd MMM dd hh:mm:ss yyyy" The code I am using is the following to test against an array to see if the date is encountered, once it is I want it to convert it to a VB based Date.

I have the code below (found on forums) that should read the string "34,56,23,74,69" starting from the first address of another process till the end. However when I start the project I receive this error :"PInvoke restriction: cannot return variants." With Search Engine for example, the string is found, displayed and changed without any problems. Right now I have a subroutine that searches the string but only if I put the right memory address, and unfortunately the address changes almost every day.

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
I am writing a command line application in VB.NET. This application is calling another one, msxsl.exe, to run an XSL transform. I am using the Process class to do this:[code]What I want it to be able to display the output from this process to the console of my application. I have read several posts explaining this method, but it does not seem to work in this case. The output is an empty string.[code]I have verified that if I run the msxsl executable on its own (i.e. running "msxsl.exe base.xml test.xsl -o styled.xml"), it displays output on the command line. What am I doing wrong?I should note that the msxsl process is currently failing due to a malformed XML file. It is displaying this error message:[code]This is exactly the type of thing I want displayed in the console of my application (or, eventually, a log file.)
View 1 RepliesI have a program that requires a string. The string is 20 characters long. The string also have to be split into 2 words the first word is 12 characters and the second is 8. If the strings is not 20 characters long I get an error. I wanted to know how can I get the program to start back over and let me enter another 2 more words if the string is not 20 characters long. At the moment after I get the string is not 20 characters long error it continues to read the rest of the program but I want it to stop after an error and let me start over from the beginning.

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?

Okay Now I only get two errors (I dont know how to solve them)
Error3Class 'BaseApp' must implement 'Sub OnCompilerError(errors() As CompilerError)' for interface 'IScriptManagerCallback'.
And
Error4Class 'ScriptManager' must implement 'Sub CompileAndExecuteFile(file As String, args() As String, callback As IScriptManagerCallback)' for interface 'IScriptManager'.
But What I would also Like to know (as well as how to fix the errors), is would the code work?
I need a regular expression that can validate that a string is an alphanumeric comma delimited string.
Examples:
123, 4A67, GGG, 767 would be valid.
12333, 78787&*, GH778 would be invalid
fghkjhfdg8797< would be invalid
This is what I have so far, but isn't quite right: ^(?=.*[a-zA-Z0-9][,]).*$
Problem: Your task is to take input from the user in string and give the following options to the user in a menu.
1- Find a String
2- Create sub-string
3- Erase a portion of a sting
4- Replace a word in the string
5- Count number of words and characters in the string without spaces.
6- Capitalize first character of each new sentence and convert the rest
of the characters to lower case.
7- Sort all the words in alphabetical order. (Use Bubble sort algorithm to perform sorting).
To perform all the above mentioned tasks you can only use pointers. Create a function to perform every task.
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.
