Have you verified those paths in the resulting registry entries?
Also the Ole View tool that used to come with Visual Studio was a great way to verify a COM components registration and even instancing it. It is now a SAMPLE and you can download it[^], build it and run it to verify COM components are accessible.

Yes, I did verify the paths in the reg entries and they checked out.
I will try the OleView though. Thanks for the pointer!!!

Try adding the /codebase switch to regasm, that adds the path to the registry of where the DLL is located. If you don't then it assumes it's somewhere in the PATH variable.
|
|

Aha! I will try this. I hadn't done it because I thought /codebase would only work in certain situations, but I will for sure try it and see if it works. Thanks!

Unless your assembly is registered in the GAC or in the system path then you need this. However don't move the DLL once you've registered it with that command because it won't be able to find it then.

I have a few more questions:
1) If the Com-Visible "wrapper" DLL, which is Com registered and seen by Com clients, wraps another DLL, does this other DLL also need to be COM Visible, registered via regasm /codebase, etc.? My Com DLL references another which references several others. Do all the DLLs need to be COM Visible? I thought that it was only the wrapper that had to be visible but maybe this is not the case?
2) And are there any bad side effects for other .Net applications that also consume a COM-Visible DLL (but not through Com)?
Thanks!

1) No, if it's wrapping it through .NET code.
2) Not that I know of, depends on how you code it mostly. Situation dependent (e.g. accessing shared resources).

Thanks, Ed!
I will put in some logging or something to try to figure out why the calls to my wrapper dll seem to do nothing on the com machine, but have the intended effect on the .Net machine.
Glad to hear it took you 2 weeks to get this working; I have been pulling my hair out over it since Friday!

THAT WORKS! You're a genius!
Now I have to debug the assembly, which doesn't seem to work, but at least I can compile!
THANK YOU!!!!

Don't worry it took me 2 weeks to get that little gem working to call a C# dll in Delphi 5.

How do I keep people from browsing sub folders on a .net website?

how about adding a simple index.htm file in each of them?

Index.html won't do it because it's a .net site. Right now, I'm using a Default.aspx file set in each sub folder.

Authentication and a web.config in the subfolders you want to be protected.

But the catch is non-ASPNET parseable resources still bypass aspnet_isapi.dll and web.config may not be able to halt them. An IIS level control is required.

True - but John is working on a .NET site so he's probably got the necessarys right there.

There is also a hidden catch.

Need authentication integration, or something simple?
Theres a couple of free .htaccess solutions kicking around.
If you want the integration have a google for the wildcard mapping in IIS to convince it to push all requests thru the ASP.Net isapi dll...
Messy though... are you sure you can't stream the files out (using URL rewriting if you really need nice paths)? Actually you could probably have a generic handler using URL rewriting to pick the file off disk and stream it out. Messy again though heh.

Am I missing something? What about the "Directory Browsing" check box in the IIS console properties?

You must have forgotten that I'm not using IIS...

I am starting with .net and I wonder how I can load a menu from my resources.
I'm looking for something like CMenu::LoadMenu() of MFC.

Hello,
I have created the shared assembly by giving it a strong name and then registring it with gacutil -i TestAssembly.dll
My issue is how can I reffer the shared assembly in the .net applicaiton.
Do I need to browse the path of the dll and add a reference to it? If yes then what shall be this path? The c:\windows\assembly?
Please let me know.
Regards,
Pavas

No. Just open up the Add References tab in Visual Studio and refer to it in the .NET Assemblies tab. If you've added it properly, it should be visible here.

|
|
|

How can I get the Assemblies in .NET Assemblies Tab?
I have created a stong name key and then I used the gacutil -i "Path of the Bin\Release\Tetassembly.dll"
Is this correct?
Regards,
Pavas
