I'm working in VB.Net. I have a textbox in which the user enters a number of strings seperated by comma. I store this value in a string array like this
Code:
Dim Src() As String
Src = txtVals.Text.Split(",".ToCharArray)
I want to search a dynamic string in this array. How could I do it in the fastest way?

I have an Array of String that contains all of the OPC Items that I wish to read from the OPC Server. When I attempt to use the Array of String, Option Strict causes the following compile error message:Error 5 Option Strict On disallows narrowing from type 'System.Array' to type '1-dimensional array of String' in copying the value of 'ByRef' parameter 'ItemIDs' back to the matching argument.

I have an array defined As string and the value stored in site is like "7E", "A1" and so on. But in order to send out this array through serial port. I need to change the the array to As Byte instead of using As String. How can I convert it?
View 8 RepliesI've been working with a sig capture application sample on a windows mobile device, The data is sent via IP to a host as a byte array and is then drawn onto the screen of the host as it appeared on the client. I was able to get this into the form of a bitmap object so I could print it or save to a jpg file. That all works well. The problem now is that I need to store this data in a database and then be able to recall it at a later time and recreate the signature image.
The byte array data is much smaller than the actual image so I would like to store it in that form. My issue is that when I convert this byte array into a string and back again my program can no longer re-create the image. Once I saw the problem I created the code below as a test and added the msgboxes to get an idea what was happened to my data.

I have :
Dim i(,) As Integer = {{2, 5, 6, 7}, {32, 5, 4, 2}}

For example :
// Here, array i has 2 sets of data i.e. 2 rows
// set1 = {2,5,6,7} and set2 = {32,5,4,2}
// So, I want the number of sets i.e 2 in this case !

I have an array where it storing all the analyzed values.
