DLLs - Error "newForm1 Cannot Expose Type 'form1' Outside The Project Through Class GlobalData"
Feb 18, 2010For a test scenario I have a dll project. In the project I have 1 generic class 'GlobalData' and 1 form 'form1' in the generic class I would like to make a public shared newForm1 as new form1 the line of code I'm trying is: Public shared newForm1 as new form1 I get the error newForm1 cannot expose type 'form1' outside the project through class 'GlobalData'. I really need to be able to make a public shared reference to form1. Any way to get around this? Background as to why I need to do this: I have several projects that need to use Form1 as a mdi child. I would like to just update the dll and not have to go back and update the same form in 50 projects.

Apr 23, 2012I have a Public Class called "ClientConnection". Inside that class, I have a Public ReadOnly Property called "FileTransfers(ByVal TransferID)". The property returns an object of the class "FileTransfer". All methods in FileTransfer are set to public.

Transactions - Expose Private Fields Using A Partial Class?
Nov 12, 2010I am trying to implement transactions across multiple TableAdapters in VB.NET (using Visual Studio 2010) by extending the partial class as described in the following examples:

View 2 RepliesExpose Information About A Running .NET Exe?
Jun 6, 2010I have a .NET exe that I wrote and it has a couple properties that I made public and want to expose.
I want to shell this exe (Process.Start()) and then somehow reference this exe and get access to these public properties. These properties expose information about the running exe.
I know how to shell to the exe. And I know how to add a reference to the exe from my project that I want to use this object. But how do I get access to the properties of this running exe?
If you do know the answer maybe you could just tell me what the standard method is to expose properties of a running exe to another application at run-time.

C# - New COM Component In Old Codebase Does Not Expose New Properties?
May 15, 2012I maintain a WinForms application that uses a third party COM component. We recently upgraded to a new version of the component with some additional properties/features (all old properties are intact), but I could not get Visual Studio to detect the new properties. It acted very much like it was hanging onto a reference to the old version of the component. Here are the steps I took to try to clear it:
Deleted the form that was consuming the component (copied out code first). The only control on this form was the third party component.
Removed the reference to the old component Deleted the bin and obj folders in the solution directory so that the PIA's would get newly created when I added the new control Uninstalled the old component, installed the new one Opened the solution, added the reference to the new component Added a form to the application, dropped the component onto the form and gave it the same name the old control had (so that the rest of the application didn't have to be refactored Pasted the form code back in place At that point the application would compile and run, but I could not get Intellisense to detect the new properties, and if I put them in place anyways the application would not compile. Nothing I tried would get the new properties to show.
