Defining a regular expression in the application settings xml file.

Posted By:      Posted Date: October 11, 2010    Points: 0   Category :.NET Framework

I have a little question about application settings. I have a regular expression in my code which should be customizable by the user so I made an application setting for it.  The regular expression is used in a class in the project and has the following value

Dim email_regularex As String

So now I made a new Settings file in my project and gave the following value for this string in the settings file:



So when i do this in Visual Studio 2008, Visual Studio automatically creates a app.config xml file with the right settings in it.

But when I start my application and use the regular expression like this:


 myMatch As

 Match = Regex.Match(email, email_regularex)


 myMatch.Success Then

 MsgBox("Please enter a valid email address like: iiiiii@iii.com"

, MsgBoxStyle.Critical)


the application break

using application settings in VB expression


I have a simple workflow that is hosted in a simple application that has a app.config and appropriate settings file.

In the settings there is a connection string and a timeout value.

I have a coded workflow activity in an activity library that can receive a connection string and timeout as input parameters.

So when I add this activity to my workflow I have to pass values to the parameters using the VB expression syntax in the expression editor. What expression can I use to refer to the settings ? My.Settings.MyConnectionString does not seem to do the trick. I have tried several possibilities but have failed to find it up to now. I had to modify my activity itself to access the settings but since it is in a seperate activity library I have to go via the configurationmanager which seems a bit less generic than simply passing in the connection string as a parameter.

Read Excel file from Web Application (C#)



I have a web app where user uploads a file.

File is saved in server locally and I want to read some data from it.

Currently my development  server has office 2003.

So do I need office 2007 in order to be able to  read an excel from office 2007 ?

What are other requirements  ?

I tried a test, using

Microsoft.Office.Interop.Excel.Application excelApp = new Microsoft.Office.Interop.Excel.Application();
Microsoft.Office.Interop.Excel.Workbook wrkBook; // = new Microsoft.Office.Interop.Excel.Workbook();

wrkBook = excelApp.Workbooks.Open(@"C:\www\excel_files\b.xls", ....);

But When trying to open the file I get the error:

Exception from HRESULT: 0x800A03EC

So I'm wondering what I'm missing.

An example of packaging web application containing database upgrade SQL file

A few months ago, we have a blog talking about extending the web publishing pipeline to package database project deployed SQL file.  In this blog, I'll show step by step example of packaging web application with SQL Server database upgrade SQL file using Visual Studio 2010.  This way, we can generate a web package with incremental SQL script to certain database version.  The scenario may help distributions of a web upgrade package which needs to be installed on many different locations, each with their own SQL server database.   1. Create a Web Application Project 2. Add a new "SQL Server 2008 Database Project" to the solution 3. Prepare a development database, such as my test1 database as the following: 4.

	<tr class="blackbar" align="center" style="background-color:#7FB4DE;font-family:Verdana;font-weight:bold;height:20px;">

Need a regular expression


I have a required field validator for a texbox, but I just found out that the texbox can have a space in it (for a delimiter, let's say).

I checked the .net and regexlib.com, but couldn't find what I was looking for.

I simply need a regular expression that basically excepts any character string including spaces in it or even a space by itself

Can someone help me out?

Matching set of characters via regular expression

I need to be able to match sets of quote and space characters in a string and replace these accordingly. I currently have this done in 2 lines of code, but would like to use regular expression so that I can use only 1 line of code. See below: var Qt = unescape("%22"); //quote char var Sp = unescape("%20"); //space var Cr = unescape("%0d"); //carriage return var Lf = unescape("%0a"); //line feed var CrLf = Cr + Lf;  //carriage return & line feed stringOut = stringIn.replace(Qt+Qt+Sp+Qt,Qt+Qt+CrLf+Qt); stringOut = stringOut.replace(Qt+Qt+Sp+Qt+Qt,Qt+Qt+CrLf+Qt+Qt);   I want to replace space in string like in pattern below with carriage return line feed: (in hex) 22 22 20 22 or 22 22 20 22 22. This needs to return 22 22 0D 0A 22 or 22 22 0D 0A 22 22   Line in green above will only match and replace 22 22 20 22 , but I want have regular expression into 1 line of code which  will match and replace either 22 22 20 22 or 22 22 20 22 22
