I have a vb.net application which I'm trying to run in VS 2008. The application builds successfully, however, when I try to debug the windows application it throws the following error, "Retrieving the COM class factory for component with CLSID {794D671E-F0F0-11D2-BEB0-009027438003} failed due to the following error: 80040154." I've been searching for a solution for a few days now with no luck. I've tried to register the referenced DLLs (w/regasm command), messed around with the configuration manager, etc. Also, please note that the application ran successfully in Windows XP, but it no longer seems to work since I've upgraded my OS to Windows 7 (I've tried to run the application in x64 and x84 platforms w/no luck). Also, I'm referencing the following DLLs:
"Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80070005."

I am facing one problem that when i try to access a page in the website, i am getting the following error,

I went to that particular class file which is in the form of dll and in codebehind page of that class , builded the application, but it is not showing any compile time errors, but i put a break point it fails.

I have been founding an effiecent way to retreive values returned by LINQ 2 SQL stored procdure on my presentaion layer. Am using following method rightnow:-
public List<String> MthInvitesBA() { List<String> lst = new List<string> { "" }; ISingleResult<USP_Actor_View_InvitesDetails1Result> invites = obj.USP_Actor_View_InvitesDetails1(p_UserName); foreach (USP_Actor_View_InvitesDetails1Result c in invites) { lst = new List<string> { c.Invites_Used.ToString(), c.NoOfDoc.ToString(), c.Request_For_More_Invites.ToString() }; return lst; } return lst; }
It works but at the cost of my performence due boxing unboxing on BA layer as well as on design layer. Now, I have one method which returns me 100 columns from table So in this way i have convert 100 coulmns value into type string then On design layer again have to type caste some values .Moreover, i could only access this list using index which is of type integer, which is very diffcult and tedious task to debug d code. i could effiecenlt retreive these values. Is it possible using IEnumerable? How to access Ienuemerable in design layer?

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

Is there anything special you have to do to retrieve Filestream data using a SqlDataSource? I'm using VB and have this as my sqldatasource:
<asp:SqlDataSource ID="SqlDataSourceReadPD" runat="server" etc... SelectCommand="SELECT [PDIPAttachment] FROM [PositionDescriptions] WHERE ([CP_IDString] = @CP_IDString)"> <SelectParameters> <asp:Parameter Name="CP_IDString" Type="String" /> </SelectParameters> </asp:SqlDataSource>
PDIPAttachment is a FILESTREAM column in my table called PositionDescriptions
and this is some of my VB cod:
Dim dv As DataView = DirectCast(SqlDataSourceReadPD.Select(DataSourceSelectArguments.Empty), DataView) Dim dr As DataRowView For Each dr In dv Dim data as Byte() = System.Text.Encoding.ASCII.GetBytes(dr("PDIPAttachment").ToString()) Next
The Filestream data has a PDF file in it, but what I"m getting back in "data" are 13 bytes consisting of: "System.Byte[]".
I have an application that uses Crystal Reports downloaded from SAP for Visual Studio 2012.
When I debug the software in Visual Studio it works perfectly fine, but when I deploy it and want to view the Crystal Report, I get the following error:

I am getting the following error when I try to establish ftp remote connection using the 'copy web site' feature on visual studio 2005.
unable to open the web 'ftp://209.*.*.*/httpdocs'. The computer is disconnected from the network.
Why can't I connect to the remote site on visual studio 2005? I can do the same thing on Dreamweaver with no problem. I can ping the IP successfully. I can open the ftp URL on a web browser with no problem.
I've added a reference to Microsoft Excel. Actually I'm uploading Excel file and doing some calculations on it. It works fine with my PC. But when I upload it onto the site and through it when I try to open Excel file it fires error : Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80040154. How could I resolve this onto my server. It's fine with my pc.
For some reason, when im making changes to .cs files in my project visual studio seems to freeze for a while, then kick back in. It doesn't happen when editing aspx files or their code behind, just files within the app code directory.
I'm wondering if its got something to do with the fact that most of the classes under app code are using the same namespace, where as the forms/controls i'm using aren't namespaced? Originally i thought it was lack of ram, but after putting 4 gig in it still freezes, it just doesn't lock the computer anymore :D
Net Framework 2.0 Net Framework 3.5 and when I use ajax, butlater when I use add-I add objects to be added soon. Why can not I add the Net Framework 2.0, also doing a mistake somewhere.
I have a solution consisting of many projects. it's very hard to trace your way around to find the right class or method to change , which led me to try to create a diagram that can model the whole solution. Is there a tool in visual studio ( class diagram designer or rational rose ) or even a third party tool that can revers engineer the solution and generate a class diagram, including all the classrelations,compositions,hierarchies and etc.
I'm developing a class library for a standalone software tool. The example class library I'm using as a template, which worked in VS2008, does not in VS2010. It compiles alright, but the external program does not get past the splashscreen when launched from VS2010 in release or debug mode. The project uses .NET 2.0 and I'm on WinXP.
I have two classes (say someclass.cs and someclass.generatedcode.cs). How do I make the someclass.generatedcode.cs inside of someclass.cs (something like a code behind) in visual studio?
I have upgraded to VS2010 recently. Now VS2010 is not opening i get an messg box displaying. Microsoft Visual Studio has encountered a problem and needs to close. We are sorry for the inconvenience. It automatically gets restarted and displays the same message. I have re-installed VS more than 3 times.
We recently converted the VS.2005 application into VS2008 in XP machine and it was working fine like compiling with out any issues and working as expected. But recently team upgraded laptops to Win7 when trying to compile it we have got issues then we changed the compiler settings to 'x86' and compiled it went good. But after that login screen came when ran the applciation without environment selection (production, DEV, Testing etc). basically we are getting this environment setup from system registry, we uderstand that Win7 is looking in different location hence no environment information is coming up..later we see that where the code is looking for environment environment and created environment keys in registry, after that environment infromation displayed in login screen but not able to login into applciaiton throwing exceptions like " Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))"
I've build a Class Library, in the same project i put a web project. But its impossible to access the classes from the dll generated by the class library. Whats wrong? JumpTide XML uses the namespace like:
namespace JumpTideClassLib { public class jumptidexml { public class MetaTags {
I've always just used incremental search, but have recently starting using a class browser plugin for vim and would like something of the same in Visual Studio to navigate methods, properties, etc. in a browser type window. Seems like this is what Class View is for, but when I'm on a page's code behind, it doesn't show up on the class view window.
When I search for the class, it shows up but when I click on it I get "The definition of the object is hidden.". Is there some basic setup thing I'm doing wrong or does VS not support class view for page classes? Is there an extension that does this (I'm using VS2010)?
