Hi John.
Here is all that we have done so far.
I added COM Visible(true) for all of my public properties and methods.
I added a [ClassInterface(ClassInterfaceType.AutoDual)] at the head of my class library.
I compiled it and sent the DLL and TBL file to the developer.
He did run RegAsm (he has been doing it every time)
This last attempt he did a
regasm myclass.DLL /codebase /tlb:myclass.tlb /verbose
When he creates reference to the DLL and looks in the object viewer, he is not seeing anything inside the class library. The constructor is visible (obviously) but no public accessors or methods.

Does anyone know of a good way to marshal data into an unmanaged array of structs.
I tried using StructureToPtr with an incremented IntPtr, that I've allocated with
Marshal.AllocHGlobal, but it doesn't seem to work.

I have been researching how to customize what is drawn in a list box. The docs are great and I have had good advice and have samples of drawing images and custom strings and even multi-column lists. However, I need to find out if I can create an instance of a cust control as the item in my list box. I know the drawmode must be set to ownerdrawfixed. I also hook into the drawitem event that the listbox raises...but can't quite figure out how to get my control to draw in the list box.

===========================================================================
the erroneous code is not part of my code. I think is code generated by the compiler. What could I do? I have reinstalled the .Net Framework for the second time and nothing changes.
Thanks in advance for any answer/hint. Anyone with similar weird compilation errors?

Hi,
I just can't find any classes that provide System Information (like the OS for exanple). Can anybody show me the right direction pls?
Thanks a ton,

SystemInformation has some information,but not OS version.If you didn't find it,you can use win32 API,GetVersion

Hi,
thanks a lot. Environment was the correct answer. MSDN didn't spit it our and I'm really getting tired of the huge MSDN Lib where you just can't find anything ;(.
Once more, thanks for the sound advice.

I'm working on a distributed application, and I would like to only have the WinUI on the client machine, and keep DataAccess, BusinessRules, BusinessFacade and so forth, on a server. Is this posible? If so, how? Does anyone know of any articles related to this?
this program will be used from anywhere between three and three hundred people at a time.
excuse any typing mistakes, its 4am

There are several different ways of doing this and what you use depends on your requirements.
The easiest way is to expose a webservice on your server and have the WinUI use it. There is a section on webservices which may enlighten you on how to create them, if you're using VS.NET they're easy to use as well (right click on the WinUI project and choose Add Web Reference, then point the mini-browser to your deployed web service).
By default web services are stateless, but it should be possible to use the ASP.NET Session stuff to persist bits and pieces.
Your next option is to use Remoting. Remoting is a bit harder to put together and use, but it is more powerful as well. Nish wrote a good article on the basics of remoting. http://www.codeproject.com/csharp/absoluteremoting.asp[^] You may also want to check out the sample chapter from Ingo Rammer's book for a bit more indepth look Advanced .NET Remoting[^].
Good luck,
James

Start with building a ASP.NET Web Service. This class will be your Facade, and will invoke your business rules, and data access layers. If your architecture supports .NET code on both client and server, you can pass managed DataSets across the boundry, which will make both sides easier to write. From what I understand, you UI will be a System.Windows.Forms application. You add a web-reference to your ASP.NET Web Service to that project, and invoking methods on the facade will be a breeze.
For example, the UI want's to start with a list of customers. It calls a method on the facade: GetCustomerList( string territory ) which returns a DataSet. Behind the facade, you've got business rules that check if the user is authorized for that territory, etc. Once validated, a data access layer pulls a limited set of fields needed for this list out of the databse, limited to the specified territory, and returns it as a DataSet. This list might have just Customer Name, City, State, ZIP and ID.
Back on the client, you can drop that dataset write into a grid control to format, scroll, etc. Without round-tripping, you can sort of any of the fields. Once the user selects a customer, you call another facade method: GetCustomerDetails( string customerID ) which also returns a DataSet. If changes are made, call facade method UpdateCustomerDetails( DataSet details ).
Hope that gets you started...

Absolutely, here is a plug for my most recent article that cover how to do this: Cross Language Web Service Implementation[^], which includes a Windows Forms Web Service consumer application.

I have a MSI installer for my system. It's running smoothly on several machines, but in one specific machine, it isn't working. The MSI installs several ServicedComponents with custom install actions. Some of the ServicedComponents call COM components and apparently everything is fine and registered ok. But in this specific machine, the installer starts and goes until it shows the following error:
Install Error: Failed to generate type library 'c:\program files\crivo\drivers\bin\DriverBalanceamento.tlb'
for 'DriverBalanceamento, Version=1.0.1069.31940, Culture=neutral, PublicKeyToken=b8bf1c10d7a7a24d'.
Install Error: There is no MTS object context

For future reference, if someone have the problem:
What I needed to do to solve it was:
(the order HAS to be this: )
1. uninstall the .MSI
2. uninstall the .NET framework
3. reinstall the .NET framework
4. apply .NET framework SP2 (don't know if it's required, but I did this way just to be safe)
5. reinstall the .MSI
The tricky part was (1) to uninstall the .MSI, since it was giving the same message when uninstalling. So, the solution was to use a .MSI without the custom actions which install the COM+ components, mantaining the MSI version number and product code. Use this MSI to remove the faulty application. The rest seems necessary to rebuild the GAC again.

After install .Net framework, the programme also can't run right( mfc70.dll is not include in framework ). is that other components need install?

I hope you don't believe MFC has anything to do with the .NET run-time.

I'm trying to get my hands on the beta2 version of the .NET Compact Framework. Unfourtunatly, it is only available with VS.NET 2003 (VS.NET 2002 will not support smart device extentions).
You'd think after spending about $1000 for MSDN Subscription Professional edition, I could at least get a copy of VS.NET 2003 beta. For some reason, MS chose to only make it available to Universal subscribers, not fair! When I signed up for MSDN Pro, I was told I would get access to all beta versions of operating systems, sdks and visual studio.net.
If anyone can comprehend MS's thought process, please help me out.

Hi!
There is a need to create a custom run-time form designer under .NET. It
should be pretty similar to the Visual Studio's own designer. Is there any
control providing such functionality? (I tried to pull out smth from Visual
Studio -- no luck).
Could somebody help me?
Thanks!

John Wood
