I have a Lightswitch application that is running fine, connects to the database and shows the data just fine. I am trying to write another one using the same database but I get the error "Unable to load data". I can't find anything I've done differently with this application. I can connect to the database in the development window and see the data by using the View/Server Explorer and show table data.

I am developing a project that is dealing with CCTV camera made in china. I am provided by some DLLs from the company. Now i want to consume that dll into my application. I have tried default Visual studio's ADD REFERENCE features. then I have tried tlbimp.exe but it doesn't work.[URL]..I have search a lot about dll, some says "Check the dll header" and CLI Header. I opened this fine in notepad and I found only like "This will not work in DOS mode...". what to do next. Is there any way I can consume this file in .net.
I have already tried to add it as reference in Visual Studio 6.0 VB. even it says this is not a valis library.
Still dumpbin.exe is listing the function inside that dll.
I am confused about this scenario. Please guide me what to do with thi.

I am trying to create a Windows Forms control in VB.Net to wrap around a control in an old DLL I created in VC++ 6. I am trying to make a call to an API entry in my control:
Code:
<DllImport("myctrl.dll")> _
Protected Shared Function InitMyControl() As Boolean
End Function
However, when I add a call to InitMyControl to my control's code and try to load the form on the test project, the following error shows up:
Quote:
Unable to load DLL 'myctrl.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)
I have tried putting a copy of myctrl.dll into the Debug and Release folders of both the control library and the test project, but I continue to get the error. I even copied it to my WindowsSystem32 folder, but still no luck.

I'm using VB2010 Express for a project that uses a DLL for USB communication to hardware.
I have the DLL in the project so it's included in the install. Everything's fine & the project runs in the development environmet until I publish. As soon as I do, I get the following error when I try to run from the development environment:
Unable to load DLL 'USBConverterDLL.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)
I worked out that the DLL needs to be present in the debug directory. Any idea how to make sure it's put there automatically when the project is first published?

I created a program using visual basic. For some functions the program accesses a dll which was created using visual c++. When the program is run on a computer that does not have visual studio installed, functions which make calls to the dll generate an error: Unable to load DLL 'filename.dll': This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem. (Exception from HRESULT: 0x800736B1).Reinstalling the application does not help, and when the program is run on a computer that does have visual studio installed, calls to the dll work as expected without generating any type of error.Is there some component that is installed with Visual Studio that I need to attach to my program installation? Is there some way I can create or access the dll such that it does not need this component?

All of the sudden, I'm no longer able to build a Solution without getting an error in VS 2010. A minute ago I was able to build, and now I can't.
The error is:
Unable to load referenced library 'C:Program FilesReference
AssembliesMicrosoftFramework.NETFrameworkv4.0System.DirectoryServices.dll':
System Error &H8013110e&
I've checked and the .dll is there. I've re-booted and grabbed the latest version from Team Foundation Server.

I'm still in my novice stages of .net development, and I think I may be trying to make something too complicated.In VB.Net 2008, I'm using a SQLDataAdapter to Fill a dataset with records being returned from a Stored Procedure (SQL Server 2005).I'm using that dataset as the datasource for a gridview. Up to this point, everything is great and I understand what's happening.I'm getting ready to make my first-ever attempt at updating the data in thegridview and then pushing the updates back to the SQL dB.Here's where I'mgettingconfused...to cut to the chase, what's the simplest way to load the updates back into SQLServer?

Whereas if we again try to run the statement in debug mode everything goes fine. Basically, on alternative loads we are getting this error.[code]...

I am currently updating an application from Vs2005 to Vs2010.

I just discovered the joys of UserControl's and I was wondering if it is possible to populate the usercontrol with data from a database in the UserControl's Form.Load event instead of the form the userControl is placed on. I feel it would make using the control a lot easier if it just populated itself without anymore code.I tried it with a ListView but it gave me a bunch of errors, so I didn't know if it had to be done a certain way or if it was just one of those things that doesn't work no matter what.
