yeah, i know, i have to read your article about CLI syntax first, otherwise, i'll always stay out of that world.

I am programing a database multi-lang application.
I am slovenian so i am using also other character.

StreamReader ^sr = File::OpenText("test.txt");
MessageBox::Show(sr->ReadLine());

In file are these character:

but i get:

Thanks in advance

Found the problem.

StreamReader ^sr = gcnew StreamReader(File::OpenRead("test.txt"), Encoding::Default);

Nish Nishant18-Jan-06 5:31

18-Jan-06 5:31

Interesting! I'd have thought, that'd have been the default.

So did i...

I have found this in msdn:
ms-help://MS.VSCC.v80/MS.MSDN.v80/MS.NETDEV.v10.en/passport25/NET_Passport_VBScript_Documentation/Single_Sign_In/Advanced_Single_Sign_In/Localization_and_LCIDs.htm

for slovenian i need to set "windows-1250", but i coudn't find any way to change to this encoding, when i have tried Encoding::Default just for fun. And it worked. I think this encoding chose it self based on windows configuration.

Nish Nishant18-Jan-06 5:55

Saksida

I just went through the source (using Reflector). When you don't specify an encoding, it uses UTF8 by default. Hence your problem. Now that makes sense I guess.

Nish

Saksida Bojan18-Jan-06 6:03

18-Jan-06 6:03

I can only specificy (the way i know):
UTF7
UTF8
UTF32
Unicode
ASCII
and of course Default.

but my program requires:
windows-1250

How can i set other encoder like windows-1250 without using default?

You can use Encoding::GetEncoding("windows-1250")

Do you know where can i get entire list for encoding?

Are you trying to use CCW on the Quartz library (I assume it's a COM library). And if so, in what way is it not working? You said Duration failed - do you mean that a call to GetDuration failed?

If the error is more on the COM side, you might have to repost this question in the COM forum.

Strings and other resources

After having such a piss-poor time with VS2005 destroying WinForms whenever I alter resX files, I gave up on it and put string literals directly in code. Now that I'm going back and doing cleanup, I want to remove those and put them into a resource file. Has anybody else had this same problem with C++/CLI projects? If so, how are you managing string resources?

If you can outline the minimal steps to reproduce the problem, I can check if I get it too.

I asked the same question on the MSDN forums and received a good suggestion to create a second resX file and placed localizable strings in there. I think I'm going to do that.

debugging VC6.0 DLL from VS .NET 2003

Hi,

i've made a managed wrapper(Managed Extensions) for a class, that was written in C++ with VS 6.0.

It works very fine but here's my problem:

I'd like to debug code of my C++-class. Any searches with google led to nothing.
Hope here in this discussion board there are some people who can help me ?

My environments:

VC++ 6.0 which i compiled the dll (source is available)

VS++ 7.0 2003 2 project: 1 project defines a managed wrapper which delegates all methode-calls to
the aggregated C++-class.

Thanx in advance

Eddy

VC 2003 does support mixed-mode debugging, but it's slow and doesn't work well all the time. You could force a debugger break by using an __asm int 3
