Test A String Of Text That To Contain A Certain Type Of Char Values?
Dec 1, 2011I need to test a string of text that needs to contain a certain type of char values. The known is allowing of a-z,A-Z,0-9. But the variable (which will be coming from a database field) will be the allowed symbols. The allowed symbols will look something like:!@#$%^&*()
So using regex, how can I check a string of text to make sure it ONLY contains a-z,A-Z,0-9 AND the allowed symbols as shown above? Remember, the allowed symbols is dynamic at run time so I need to somehow be able to plug that in to the method at run time.
The following examples would be valid using the above symbol string:
Test1234%
Test1234
The following example would NOT be valid:Test1234%_

Sql Server - Test Function In MVC Project?
Jul 27, 2010So I want to test one of my Functions in my Web Project, but it's not actually connected to anything in the project yet (someone else is working on that part). The Function takes in an "ID" field, goes off and does some queries and gets some data, performs some calculations on it, and then writes a bunch of lines to a FileStream and returns that stream. I pretty much just want to test it by having it write the file to my own computer locally, and working with that file directory after the Function completes.
So my question is mainly:
1) How do I call this Function just for testing purposes so I can test all the queries/calculations/File writes, etc without it being connected to another part of the application just yet.
2) How can I change the 'Return fs' for the FileStream to write to my own computer locally to view the file that has been written.
Why Is String Returning A Char
Jun 27, 2012I 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.
For Each theseRows In DisplayForm.MainTab.Rows
If theseRows.Item("Last_Name") = userLast And theseRows.Item("First_Name") = userFirst Then
[Code]....
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.

Using Char - First Letter Of String Must Be Certain
Apr 18, 2010Basically 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?

Import And Call Unmanaged C Dll With Ansi String "char *" Pointer String From .net?
Mar 11, 2010I 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
Imports System
Imports System.Text
[Code]...
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).

String / Char Arrays And Whitespace
Feb 6, 2012I 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.
