View 2 RepliesI have an application that has 3 list boxes, one selects a workshop, the other a location. the third is to display selected costs.to do the calculation a loop is required. i have written the code but when i calculate the cost the final result to be displayed ends up as being the cost of the last work shop and location * 3,What is supposed to happen is the location is multiplied by the number of days(3 in this case) and added to the workshop cost.the loop is supposed to add all cost from the list box till all have been added.what is happening is the calculation goes to the last entry as stated the multiplys this total by number of days(dbl)?

Quick background: I have a VB.NET application in which I was previously using ConfigurationSettings.AppSettings to read from app.config, and got an error message to change it to System.Configuration.ConfigurationManager.AppSettings (as the first way is now obsolete)I did so, and I even have a reference to System.Configuration.dll AND the Imports statement at the top, but I am getting a "Name ConfigurationManager not declared" error message. Any suggestions?
CODE:
It's pretty straightforward - I'm just checking if something exists, and if it does, I read from it:
If Not Exists(ConfigurationManager.AppSettings.Get(rep & "Email")) Then
Return False
End If
message = ReadAllText(ConfigurationManager.AppSettings.Get(rep & "Email"))

This is glossed over as an easy thing, but when I try to create the reference by right clicking references and selecting add reference, then going to .net, the system.configuration.dll does not show up in the list. I then did a search for the dll on my system and found it in this location:
C:WINDOWSMicrosoft.NETFrameworkv2.0.50727System.configuration.dll
I then tried to register this DLL using "regsvr32 system.configuration.dll", but I get this error:
----
System.configuration.dll was loaded, but the DLLRegisterServer entrypoint was not found.I also attempted to browse for the file using the add reference utility and it gave me an error stating that a reference to the file could not be added. "This is not a valid assembly or COM component."
I'm really stuck at this point, I can't reinstall .net framework v2.0, the system won't let me. I can't create a reference and I can't get my program to work.

If I modify this code (written by Luis Esquivel) because I want to dimension a variable and cast it either as a polyline or a polyline2d inside a select statement...it doesn't recognize the variable outside the select statment. I can't dimension it outside (or rather) before the select statement because I don't yet know how I want to cast it.
