How to declare\read value from app.config file - VB Express 2010

I need to be able to set the web service URL by editing the .exe.config file when I deploy this to end users.

This setting is a Web Service URL type in My Project>>Settings.

I tried to read the value this way but get an error:

Public ws_test As New localhost.IDataCollectionservice()

ws_test.Url = System.Configuration.ConfigurationManager.AppSettings("JobBOSS_AutoCrib_Integration_localhost_IDataCollectionservice")

"An error occurred creating the form. See Exception.InnerException for details.  The error is: Value cannot be null.
Parameter name: uriString"

I've checked My Project>>Settings and this is the value for this object.  If I can't get it to read my local web service path, I know it's not going to work when I try to edit the .exe.config file on an end user's machine.

Your thoughts on how to resolve this would be appreciated.

If you're reading from an app.config, you can add an <appSettings> section in the configuration section of your app.config.
Something like :
<configuration>
      <appSettings>
            <add key="MyKey" value="MyValue"/>
       </appSettings>
</configuration>

In your code you would acces it by using something like:
ConfigurationManager.AppSettings("MyKey")

You'd only have to import the system.configuration namespace.

Okay, I need to back up a bit.  I Know how to add setting to My Project>>Settings and I have two settings here, one is  a String type and the second is a Web Service URL type.

I can read these via my code with the following code:

        ws_test.Url = My.Settings.Integration_localhost_IDataCollectionservice
        strTest = My.Settings.Path

In order to deploy this, I was thinking I needed to get my code to read from the .exe.config (app.config in my development environment) file which I will edit on each user's machine to get the path and web service correct.      

I was attempting to use this code, but I get the error I mentioned earlier for the web service url variable and the strTest variable is = "" after this line runs so neither one is ready from app.config??

strTest = System.Configuration.ConfigurationManager.AppSettings("Path")
ws_test.Url = System.Configuration.ConfigurationManager.AppSettings("JobBOSS_AutoCrib_Integration_localhost_IDataCollectionservice")

First of all, sorry if my reply sounded harsh... I didn't mean it that way...

If you're using a regular string for the URL, you could change the type to String and not Web Service URL. Maybe that way you can catch the value as you're doing with the String type setting you already have.
