Using a Function from a Custom assembly - An unexpected error occurred while compiling expressions.


LocalReport, SQL 2005, Custom Assembly compiled in Framework 2.0, with this I can add the reference to the report.

Client  (WinForm Framework 4.0)  In the same path of my application, I have the custom assembly (that uses the report)

When I try to get the DataSources, getParameters, or SetParameters, I always get the same error. The LoadDefinition(stream) does not load anything. Any Idea?

An unexpected error occurred while compiling expressions. Native compiler return value: ‘[BC40000] 'RequestMinimum' is obsolete: 'Assembly level declarative security is obsolete and is no longer enforced by the CLR by default. See http://go.microsoft.com/fwlink/?LinkID=155570 for more information.'.’.

I also tried to enable the NetFx40_LegacySecurityPolicy in the config of my application, and nothing change.

If I don't use the Function from the custom assembly I don't have any problem.
Thanks in advance.

Custom Lookup function not connecting to data sources?


Hi folks,

I am trying to run the following function (which works in Visual Studio just fine) but it appears SSRS can't access data in the same way as Visual Studio?  There are extra permissions needed - can anyone point me in the right direction?
(I am basically trying to emulate the DLookup function from Access for a migration we are planning.)

Here's the error:

--- begin Error output

Custom Controls in C# .NET

Embedding user controls in a Windows form is just like adding a simple button or text box that are already provided with .NET. These basic controls were written essentially like you code your own controls. Typically the controls you design are to be used in multiple forms or to modularize your code. These reasons help reduce the amount of code you have to type as well as make it easier for you to change your implementation. There should almost never be any reason to duplicate code because it leaves a lot of room for bugs. So, implementing functionality specific to your control in the control's source code is a good idea. This reduces code duplication as well as modularize your code, which is a good programming guideline.

Writing custom MembershipProvider

ASP.NET Membership mechanism allows to use the build-in server tables to store and retrieve user data. By default, this mechanism can only be used with SQL Server database to which Microsoft provides suitable MembershipProvider class.
Inheriting from this abstract class, developer can use his own table(-es) from any database and use any database engine other than SQL Server, like Oracle, DB2 etc.

Custom Editing Behavior for DataGridView TextBox Columns

For various reasons I'm using a DataGridView instead of a ListView, and while configuring the DataGridView to look like a ListView wasn't much of a problem, there's one thing that got on my nerves, which is the behavior of textbox cells in edit mode: It is much too easy to leave the edit mode accidentally, simply by pressing the cursor keys at the wrong time. For example when the text caret is positioned behind the last character of the textbox cell content, and you press the right arrow key

Write Custom WebParts for SharePoint 2007

The popularity of SharePoint Portal Server 2003 led Microsoft to tightly integrate the next SharePoint version, Microsoft Office SharePoint Server (MOSS) 2007, with its ASP.NET 2.0 WebPart framework. This tight integration enables the ASP.NET and SharePoint developer to do a number of things that previously weren't possible

Writing Custom Web Parts for SharePoint 2007

As I mentioned in an earlier blog post, SharePoint 2007 is built on top of ASP.NET 2.0, which means you can now use ASP.NET 2.0 features (Forms Authentication, Master Pages, Membership, Site Navigation, New Data Controls, etc) when building SharePoint sites. This is true for both the new Windows SharePoint Services 3.0 version (which will be a free download) as well as Microsoft Office SharePoint Server 2007 (which costs money).

connection to SQL Server files (*.mdf) require SQL server express 2005 to function properly.


I dont have the SQL EXPRESS installed instead I have SQL Standard Edition.

 I have two SQL Server instances installed.

 1- UserLT (this is sql 2000)
2- UserLT\SQL2005 (this is SQL 2005 named instance)

But when i try to add a database to my VS website project I get the following error:

Connection to SQL Server files (*.mdf) require SQL server express 2005 to function properly. please verify the installation of the component or download from the URL: go.microsoft.com/fwlink/?linkId=4925

I went in Tools>Opetions>DataBase tools>Data Connection>Sql Server Instance Name (blank for default)

and changed the "SQLEXPRESS" to "USERLT\SQL2005".

But I still get the same error message. Any ideas how i can resolve this issue?

Public Shared function doubt????

I am using VB.net/ASP.NET and SQL Server 2000 for a web application.

For populating the dropdowns, I wrote a Public Shared function LoadDDL(), in which I pass the dataset and dropdown name to set.

I have my doubts that this function will produce unexpected results for concurrent users. And will mix the results among sessions because it is a Shared function.

I am confused here. Is it the right way to go?

Please advice. Thanks in advance.


How to implement custom HttpContext for each request under class that implements IHTTPHandler


Hello All,

I created an application and implemented IHTTPHandler for all incoming request ending with ".aspx" extension.

Under "ProcessRequest" module, I am creating an instance of HttpContext (with URL attributes different from my application's URL i.e. if I am working on localhost then speciying Yahoo.com as its URL) and assigning it to "context" which comes as method argument.

After redirection, an error is generated. Also, the custom HTTPContext is not passed to the requested page (default.aspx, in my case.)

Code is as follows.

    Public Sub ProcessRequest(ByVal context As System.Web.HttpContext) Implements System.Web.IHttpHandler.ProcessRequest
            Dim requestedUrl As String
            Dim targetUrl As String
            Dim urlLength As Integer
            'Save settings which will be used while redirecting to appropriate page
            requestedUrl = context.Request.RawUrl
            If requestedUrl.IndexOf("?") >= 0 Then
                targetUrl = requestedUrl.Substring(0, requestedUrl.IndexOf("?"))
                targetUrl = requestedUrl
            End If
            If targetUrl = Nothing Or targetUrl.Length = 0 Then
                targetUrl = requestedUrl
            End If
