I would like to find the index where the letter d is at, so I can get the number 3.
I managed to do it by looping through each letter in the string, but that doesn't sound very convenient.
how to remove or replace specific characters from a string. The code sample is provided contains a VBScript function to parse a string, replacing or removing any character found in the array declared at the beginning of the function.VBScript String Clean Function - Remove/Replace Illegal CharatersThe function was originally writted to remove illegal characters found in a string for use as a document file name in SharePoint Document Library.To use the function, simply update the array at the beginnning of the function to include all of the characters which are to be removed or replaced. If replacing specific characters with something else, the you will need to set inside the finction the string which will replace each character if found.The VBScript function then returns a cleaned string.VBScript String Clean Function - Remove/Replace Illegal CharatersBlogs: SharePoint Development | Web Development & Programming | Webmaster resources & free SEO

I used a StreamReader and StreamWriter with UTF-8 encoding to find and replace chars in files. Some of the chars were replaced with the Unicode default char of � OR �. I found that for this I should have used encoding 1252 so I'm set for future changes but how do I fix the files that have been cluttered with the default char? Is there a way to do this with StreamReader?

The file reads in parameters and two of the parameters used to be in Date Format YYYYMMDD but will now permanently be in format YYYY-MM-DD. This change, I believe, is stopping the import of the file from working. I would like to replace the new format YYYY-MM-DD back to YYYYMMDD in the code. If possible I'd also like to see some output so I know that the old format has been replaced with the new format. The code is below. I added the two rows with .replace code in green in expecting that to be enough but it is still not working.

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.
The following code:
If checkboxList.Items(i).Selected Then
.Fields("DESC1").Value += checkboxList.Items(i).Text + ", "
End If
should produce output such as "A, B, C,(space)", which will then be bound to a dynamically created GridView. I would like to remove the last two-char string, that is ",(space)". How can I do this?

what is the best way to remove FileFinder1 from this string:
"C:Program FilesFileFinder1"
Basically the first letter of a string must be a certain letter. At the moment the only way I know how to do it is as follows:
If sConsignmentNo(0) = "J" Or sConsignmentNo(0) = "C" Or sConsignmentNo(0) = "U" Or sConsignmentNo(0) = "N" Or sConsignmentNo(0) = "H" Or sConsignmentNo(0) = "S" Or sConsignmentNo(0) = "V" Then
Basically listening the same thing out over and over. Is there a way I can say, If sConsignmentNo(0) = ListOfValidEntries i.e J,C,U,N etc?

I have written my own function, which in C would be declared like this, using standard Win32 calling conventions:int Thing( char * command, char * buffer, int * BufSize);I have the following amount of VB figured out, which should import the dll and call this function, wrapping it up to make it easy to call Thing("CommandHere",GetDataBackHere).UPDATE:This code is now a working solution, as shown here:
Imports Microsoft.VisualBasic
Imports System.Runtime.InteropServices

Updates: I got the code to build by following the help received here, and then I had forgot the As Return Type (which got me a MarshalDirectiveException PInvokeRestriction). Then I had an assertion failure inside my DLL, which lead to an SEHException. Once fixed, this works BEAUTIFULLY. There are newsgroups where people are saying this can not be done, that VB only loads managed dll assemblies (which I guess is the normal thing most VB users are used to).
I have a string like this.
Dim str As String = "code"
I need to break this string down to an array of characters like this,
{"c", "o", "d", "e"}
How can I do this?

I am developping an app which talks across a network and will eventually be used to read in a text file (on the client) and transfer it to the server. Currently, the server and client succesfully connect to each other using the Tcplistener/Tcpclient classes. I am now trying to send some data across the network using the networkstream class, which I have implemented.Currently for testing purposes i am sending a char array which contains the characters "hello" which succesfully sends and outputs to console on the server. Although, "hello" is followed by a long list of whitespaces. I have tried converting this to a string array on the server and/or client and using the string.Trim() function (amongst trying many other things over the past couple of hours) although the output remains the same.
