If an application makes use of assemblies (what ones don’t). and both the assembly and the application need to pull some configuration values form a file, do I need one .config file for the app and individual ones for each assembly?

…Or do the assemblies use the applications .config file because they are running inside of it?

I am kind of hoping that they can all share a file….

Exposing C# DLL to COM -- almost there

I have a component that we need to move out of the .NET world and expose to a VB6 application. In the IDE, I checked the box to register for COM and I tried to follow the advice given in the popup box.

So I strong named the assembly. That, with the checkbox, gave me the dll and the tbl file after compilation. I seem to still be missing the metadata file for the component and that is stopping the VB6 code from seeing the methods and properties. Is this something I must build manually? If so, how do I know the format of the metadata file???? If not, what am I missing that is preventing the metadata file from being built when I compile?

Any help is greatly appreciated.

Well, you already have the 2 pieces needed to use your COM objects. Part of the process is that the type-lib and assembly files (tlb & dll) need to be registered using regasm.exe. That utility can be found wherever the .Net Framework is installed - typically in the folder "C:\WINNT\Microsoft.NET\Framework\v1.0.3705" on Windows NT & 2K.

I've found that I don't need to register the tlb file since when I regasm the dll, it also does the embedded tlb as well (it also MAKES a tlb file for you too).

I should think that this is being done for you when you compile your project. However, this is a project setting and may not be set/active/non-existent in your project.

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.

Marshaling to unmanaged struct array

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.

owner drawn lists

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.

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,

In theory, there is no difference between theory and practice. In practice, however, there is.

Try using System.Environment. At first glance, it looks like it contains what you are looking for:

MachineName<br />
OSVersion<br />
TickCount (system uptime)<br />
SystemDirectory

etc.

Mybe this, in conjunction with SystemInformation would be a good set to start with.

this program will be used from anywhere between three and three hundred people at a time.

Dan Smith wrote:

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,

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...

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'

Does MSI installer work in other situations (eg framework installer)?

Does it successfully "generate" other "type libraries" in that dir?

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.

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.
