Lets hope my MC++ app is not screwed up in some other way huh? ;) regards, Paul Watson Bluegrass Cape Town, South Africa The greatest thing you'll ever learn is just to love, and to be loved in return - Moulin Rouge Alison Pentland wrote: I now have an image of you in front of the mirror in the morning, wearing your knickers, socks and shoes trying to decided if they match!

It is going to serve a couple of purposes, firstly give me more experience developing a proper software application (as opposed to programming/software development theory that I've covered at Uni. Originally, the idea for the application came from my Uncle, who wanted to do something, but didn't know of any existing software package that would do what he needed -- so I took it up as a bit of a part-time project. I'd imagine that the majority of the code would be unmanaged, and ideally I'd just go with MFC and ATL. However, developing COM servers in ATL appears a little daunting, so I thought about delving into Managed C++. I prefer the UI functionality in MFC, as well as the stricter Doc/View architecture. However, the .NET framework encompasses all the "other stuff" pretty well (from what I've seen through developing the odd C# app and ASP.NET app), so it seems an ideal solution. All I've got to do now is pick up a copy of VS :)

Glad to help - I spent some time last night implimenting a typed dictionary if XmlNodes to paths and values, so it was perfect timing.

Hi Paul, Create an MC++ console test-app and put the same code into it and see if it works from there. It's prolly easier to debug too. Regards, Nish Author of the romantic comedy Summer Love and Some more Cricket [New Win] Review by Shog9 Click here for review[NW]

But still it is a good practice to have it in the InitInstance Yes, in fact I did not add it myself. The app wiz had put it there for me. Rama Krishna wrote: MFC requires AfxOleInit in order for control containment to work and I am surprised to see that in VS.NET it is automatically called during CreateControl I had looked at the different overloads of CWnd::CreateControl but had not found any call to AfxOleInit, but just now I found that COleControlSite::CreateControl does indeed call AfxOleInit Rama Krishna wrote: Now to the actual answer.

Nishant S wrote: I hope some of my MC++ intro articles were useful Most definitley Nish. You are a great editor and article writer. You should check the messages on your articles, I posted one (the MC++ intro that that one idiot wrote that nasty post on.) Nishant S wrote: Cool! I am submitting one too Ahh damn, and here I was hoping I was going to win, and then you come along.

I don't think that's what the lounge is for.

Hello Rama/James It's a well know bug it seems. It happens when you use gcroot in an MFC application compiled with /clr. See this reply from a Microsoft guy in reply to a similar question that got asked in the dotnet mailing list. From: "Mark Hall (VC++)" markhall@MICROSOFT.COM Subject: Re: gcroot template with warning C4244? This is a mismatch between the way the GCHandle class is defined and the way C++ implements the -Wp64 warnings. In short, intptr_t and System::IntPtr were not recognized as fully compatible. This will be fixed in the next release. Author of the romantic comedy Summer Love and Some more Cricket [New Win] Review by Shog9 Click here for review[NW]

Don't ya hate it when that happens. Regardz Colin J Davies Sonork ID 100.9197:Colin I am sick of fighting with Martin, I think I will ignore his posts from here on in, and spend the time working on articles instead. Christian Graus

It's not about bad design here Alex. I don't have a choice here. A remote client may do what it wants to. We cannot dictate to it to close after a minimum while :-( I like your periodic flush idea. I'll do that. And yeah, I'll take a look at your Dataset article too :-) Thanks Nish Author of the romantic comedy Summer Love and Some more Cricket [New Win] Review by Shog9 Click here for review[NW]

That's right. :) I found the answer in the .Net SDK. But there is one requirement - both threads must be in the STA apartment, otherwise the function call on the interface will fail. 43 68 65 65 72 73 2c 4d 69 63 68 61 65 6c

Thanks. This really looks like a solution. Best regards, Alexandru Savescu

Well 20 Mb is not so bad given that it does a LOT! And in newer versions of the MS Operating Systems, they'd have the runtime by default! Nish Author of the romantic comedy Summer Love and Some more Cricket [New Win] Review by Shog9 Click here for review[NW]
