'Window' not type of element 'WindowInstance' Error

Posted By:      Posted Date: October 04, 2010    Points: 0   Category :WPF

I've been teaching myself WPF for about a week now, so I'm sure this is something easy.
I have made a project to contain my 'Themes' for a window.  Assembly= libThemes   Namespace= Theme_Library
The only item in this is a ResourceDictionary in the file generic.xaml (in the 'Themes' folder) with a code-behind generic.xaml.cs .
The markup of this file looks like this...

Type or namespace error.


A couple of days ago I started getting an unusual behavior when compiling Website projects. I have referenced class libraries added to my bin folder that are also correctely referenced in using statements in my aspx.cs code behind. When I compile, I get the 

Error 4 The type or namespace name 'CommonClassLibrary' could not be found (are you missing a using directive or an assembly reference?) C:\Dev\Fiscal_Portal\Implementation\FMS Portal Site_new\App_Code\BLL\DataTables.cs 1 7 C:\...\FMS Portal Site_new\

The type or namespace name 'CommonClassLibrary' could not be found (are you missing a using directive or an assembly reference?)

error message that would typically be received when the dll has not been added as a reference or added in a using statement.

I can eliminate the error by adding an


Activation error occured while trying to get instance of type Database, key "DBName"


Im using Enterprise library 5.0
I have a scenario, where I have to access two different databases in my application.

Basically this application is a webservice,delployed on my local for testing purpose.
I'm trying to access this web method from diffent windows application, default connection works fine but the other database throw's exception.

Problem is only my defaultDatabase is works fine, if I change defaultDatabase="MYCON1" with "MYCON2" it works fine, if I try to access the other database which is not default, throws exception.

Open PopUp Window From Error httpModule


I would like to open a popup window from the assembly to present the information to the user. Does anyone know if this is possible, I am presently doing the following:

"Type ASP.x is not defined" error for dynamic user control when publishing updateable


I have a user control (ContainerCtrl) which programmatically instantiates another user control (SimpleCtrl) in OnLoad. It builds and runs fine, but when I publish it I get the error "error BC30002: Type 'ASP.SimpleCtrl' is not defined." (If I publish without the "updateable" option there's no error, but I need the site to be updateable.)

I assume this has to do with the particulars of how the assembly(ies) are built for the different compiler options. My question is, how can I get it to work properly for "updateable" publishing?

VS 2008 / .NET 3.5 sp1

The code follows (web.config is the default from Visual Studio).

Many thanks, Dave

'Unspecified error' doing sp_xml_preparedocument on XML element with a long attribute

In SQL Management Studio 2008 (connected to SQL 2005 database), I get this:The XML parse error 0x80004005 occurred on line number 2, near the XML text "<item value="&#xD;&#xA;libname...Msg 6602, Level 16, State 2, Procedure sp_xml_preparedocument, Line 1The error description is 'Unspecified error'.When I do this declare @doc nvarchar(max), @idoc int set @doc = '<item value="&#xD;&#xA;libname..." />' EXEC sp_xml_preparedocument @idoc OUTPUT, @doc when the value of the @value attribute is actually a string of somewhat over 830000 characters.If I truncate the string somewhat, the statements execute successfully.Anyone know how to fix this?  (and "use shorter attributes" is not an acceptable answer :-)I would use XQuery except that I can't figure out how to get the equivalent of @mp:id and @mpparentid to give me the hierarchical structure information I need.  If anyone knows how to do that, I'd appreciate a hand there too!

Error Build: Type or namespace could not be found, when referencing a web service

Hello, I'm new in writing C# application in Visual Studio 2008. I'm currently writing a web application for CRM 4.0 Reporting Service rendering. I reference my web application to our Reporting Service web service http://reportservername /ReportServer/ReportExecution2005.asmx and name it 'RSWebReference'. Then I want to reference it in my code: Using RSWebReference; Not sure why, but I cannot build my solution, saying "The type or namespace name 'RSWebReference' could not be found (are you missing a using directive or an assembly reference?)". I read this thread in http://social.msdn.microsoft.com/Forums/en-US/sqlreportingservices/thread/74f70e30-83e8-4817-b5e0-7729450730a1 that the website probably is using .net 1.1, and I should change it to .net 2.0. However, I think the website is already using 2.0. Is it probably because I'm using VS 2008? How can I tell and change if the website is using 1.1 or 2.0? Or could I be doing something wrong? Thanks in advanced for your help! -Elizabeth K.

Error - "Specified element is already the logical child of another element. Disconnect it first."

What I have is a Grid with each cell containing its own canvas.  I have a UserControl (uc) that I want to be able to drag/drop to other cells within grid.  I was able to get my drag/drop of the uc working except for the error in the subject.  On a drag/drop of a uc, I determine the canvas the drag started in, get a reference to the uc, clear the original canvas's children and add the uc to the new canvas.  The wierd thing about this error is that it is not entirely consistent.  Sometimes, I can drag the uc around to three or four different cells before receiving the error.  I have read multiple posts about this error but I don't seem to be able 'disconnect' the uc from its original logical parent.  Help is appreciated.

Hi, I'm creating a report model (2008 R2).  I am trying to create a relationship between two tables.  One FKs to another--same name and type (tinyint) columns.  But the Data Source View editor doesn't allow this, giving the message "...source and destination column have different data types".  But the columns are the same types.  I ahd this once before  acouple of years ago and don't remember how I got around it. Does anyong have ideas?  

Strange: Parser Error: Could not load type '_Default'.

i donot have any intentions till now of uploading my web project and just started working on MS VS9.0I made a simple Linq based project (CODE BEHIND used)AS i compiled it i got Parser Error: Could not load type '_Default'.I figured out 2 solutions for this(WHICH I CUDNT FIND IN MANY FORUMS). But nt sure...why doing them solves the problem.SOL 1)The easy way out is to uncheck "place the code in the seperate file" while adding an item.and then adding the statement <%@ Import Namespace="System.Linq" %> on top of ur aspx as in:<%@ Page Language="C#" %><%@ Import Namespace="System.Linq" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">---FURTHER CODE----Sol2)If  we deal whith the CODE behind technique....and have already used "USING System.Linq; in the definition,I found a funny solution to the problem.In ur default page...the top line is<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="<namespace>.<class>" %>Now if i change the keyword from CodeBehind to CodeFile as in:<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="<namespace>.<class>

COM Interop Error loading type library/DLL TYPE_E_CANTLOADLIBRARY error in Vista but not XP

I have created a .NET executable that is using a COM assembly that is located on a servers shared drive but am  having problems getting it to work on a number of machines. I have made sure to register the COM assembly using regsvr32 and doing that it works on the computer that I developed it on. From there I brought it over to a Windows XP computer where it didn't work. I received an error message saying "Error loading type library/DLL ... (TYPE_E_CANTLOADLIBRARY)", which was in reference to the COM assembly. After some trouble shooting I found that if I granted the executable FullTrust in the .NET security model the .NET executable was able to load the assembly and everything worked properly. From there I brought the executable to a Windows Vista computer, registered the COM assembly using regsvr32 and granted the .NET executable FullTrust in .NET but it doesn't work. I get the same error saying "Error loading type library/DLL ... (TYPE_E_CANTLOADLIBRARY)". Any idea why the same steps would work in XP but not in Vista? Am I missing something obvious? Any suggestions would be greatly appreciated.
