Imports System.Xml - Error Namespace Or Type Doesn't Contain Any Public Members Or Cannot Be Found?
May 2, 2010I'm setting up a simple XML read-write demo (VB Winforms) in Visual Studio 2010 Premium (tried in both the RC and RTM) and added:
Imports System.Xml
Result: Error Namespace or type doesn't contain any public members or cannot be found...
VS 2008 equivalent example recognizes the Imports statement fine.I know this has to be me, but I'm stumped.
Note: I tried this with the app targeting both .Net 3.5 and 4.0. Same result.

View 2 RepliesSave Image Files To HD Path From A RESTful Api With Out Using Imports System?
Mar 13, 2011I am currently trying to create a DLL for use with a RESTful api. The only issue I have is that so that this DLL can be used in a service or a program without a GUI, so I can't use "Imports System.Drawing.Imaging" as this requires a form. I have looked around for examples to handle this without using this library but have had no luck.

Error BC30464: Namespace Or Type'Compatibility' In The Project-level Imports 'Microsoft.VisualBasic.Compatibility' Cannot Be Found
Jan 16, 2009I've started to use a Vista machine for development. In case it is significant: I'm using MSBee so that I can code in the Visual Studio 2005 IDE while still building against the 1.1 framework.On the Vista machine, when I tried to build a particular vb project, I got this error:
error BC30464: Namespace or type'Compatibility' in the project-level Imports 'Microsoft.VisualBasic.Compatibility' cannot be found.
The same project built fine on my old XP machine. I checked in this folder on my Vista machine:
C:windowsmicrosoft.netFrameworkv1.1.4322
...and sure enough, "Microsoft.VisualBasic.Compatibility.dll" was missing. So was "Microsoft.VisualBasic.Compatibility.Data.dll". Copying them from my XP machine to my Vista machine allowed me to build the project successfully.I'm just a bit puzzled as to why this happened. Why was "Microsoft.VisualBasic.Compatibility.dll" missing? I'm also not very comfortable with my chosen solution - copying the DLL manually. It works, but surely there must be a better way.
As far as the configuration:
Vista:
.Net Framework 1.1
.Net Framework 1.1 SP1
.Net Framework 1.1 SDK

Loop - Sub - Wrote Only To Temporarily Fill The Database In During Run Time
May 1, 2009I have a sub that i wrote only to temporarily fill the database in during run time to be able to test a few other functions that i wrote as well ... weird thing is by the way i wrote it it should only look 100 times... but by the unique ID in the database and the information it pulls back into my list box it loops 700 times before actually stopping the loop ...
Public Sub Fill_LeftOvers()
Dim x As Integer = 0
conn.Open()
[CODE]...
Now i used step debugging and sure enough it only loops 100 times during stepping but in the database it looped like crazy ... i have also tried while x < 100 instead of the do loop but it did the same thing ... i know this may be considered a double post i mistakenly posted originally in the PHP forums earlier today ...

Error: A First Chance Exception Of Type 'System.InvalidOperationException' Occurred In System.Data.dll
May 5, 2011I am using VS 2008, Office 2007, and Win7 Home Premium on my system.I have a simple application which should be a breeze to build. All I am attempting to do is pull data from an Access database with four small tables into a data grid on a windows project. Should be simple, set up the data connection, choose a datagrid from the table in the data source view, drag it onto the page and done, right?I can't get it to work. It will all work fine until I attempt to run or debug the project. The data will not show up. The data grid does, but I get this error: A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll
As I said, the project seems to build fine, but it will not pull the data. After the initial build I get the message that Windows will show this page in Compatibility View. Is it something with Win7 Home Premium, or a setting somewhere?
