Simple encrypted & versioned configuration [Simple encrypted & versioned configuration]

I needed a configuration class for my project that uses the Isolated Storage to store the values, supports versioning and user-specific encryption (using DPAPI) so here it is...

Type.IsDefined required permissions [Type.IsDefined required permissions]

TomasDeml — Mon, 19 Jun 2006 05:37:33 GMT

Hi.

I've created a sandboxed AppDomain with limited permissions and granted the full trust to my assembly. However, I'm not able to get a custom attribute applied on a type from another assembly (not fully trusted). The attribute type resides in my trusted assembly. I've done many assertions but I'm unable to determine what permissions Type.IsDefine method requires. The call does not return false only when the domain gets unlimited permissions. Even unlimited security & reflection permissions do not help.

Can you help me? Thanks a lot.

Tail. calls & Visual Studio lies [Tail. calls & Visual Studio lies]

TomasDeml — Thu, 15 Jun 2006 13:03:50 GMT

Hi!
I've been using tail. calls in my recent IL project and today I came across this post. If you go through it, you can see the performance differencies between call vs. tail. call instructions and the proof that the tail calls are barely optimized by .NET JITer. What a shame! Not only that the tail. calls are slow under .NET, but VS disassembly view lies you about the actual jitted code! Hope they'll improve the performance in .NET v4.0 (still dislike that v3.0 mess :|)

One may wonder what other things VS lies about...

Account specific magic cookie? [Account specific magic cookie?]

TomasDeml — Wed, 31 May 2006 09:25:29 GMT

Hi,
does anybody know if there is something like a magic cookie that is specific to each user account under Windows and IS accessible ONLY when the account is logged in and CAN be retrieved via some API?

I'd like to use some sort of the cookie only accessible to an authenticated user for a password encryption...

Thanks.

XP Copy Problem [XP Copy Problem]

TomasDeml — Wed, 10 May 2006 07:08:35 GMT

Hi.
I just bought a larger hard drive and I wanted to move my existing WinXP installation to it. So I installed the new drive as the Secondary Master and booted to my XPs. Then I used Partition Magic to copy the system partition on the new disk. After that, I installed the new one as the Primary Master and removed the original one.

But now, when the mirrored XPs boot, they just freeze during the logon. The weird part is that when I plug the original drive as the Secondary Master, the boot is ok, except a few crashing svhost processes.

I read somewhere that you have to remove all the disk controllers from the Device manager prior to the copy (?).

Has anybody experienced this problem? I just don't want to reinstall XP and download all the updates :(

Thanks A LOT.

C++ Union Conversion [C++ Union Conversion]

TomasDeml — Tue, 21 Mar 2006 17:40:47 GMT

Hi!

I have this C++ union:
[code language="C++"]
    typedef struct {
    BYTE type;
    union {
        BYTE bVal; char cVal;
        WORD wVal; short sVal;
        DWORD dVal; long lVal;
        struct {
            union {
                char *pszVal;
                TCHAR *ptszVal;
                WCHAR *pwszVal;
            };
            WORD cchVal;
        };
        struct {
            WORD cpbVal;
            BYTE *pbVal;
        };
    };
} DBVARIANT;
[/code]

I converted it to C# this way:
[code language="C#"]
    [StructLayout(LayoutKind.Explicit, Pack = 4)]
    internal struct DBVARIANT
    {
        [FieldOffset(0)]
        public byte Type;

        [FieldOffset(1)]
        public DBVARIANT_SUB0 Sub0;

        [FieldOffset(1)]
        public DBVARIANT_SUB1 Sub1;

        [FieldOffset(1)]
        public DBVARIANT_SUB2 Sub2;
    }

    [StructLayout(LayoutKind.Explicit, Pack = 4)]
    internal struct DBVARIANT_SUB0
    {
        [FieldOffset(0)]
        public byte bVal;

        [FieldOffset(0)]
        public char cVal;

        [FieldOffset(0)]
        public UInt16 wVal;

        [FieldOffset(0)]
        public short sVal;

        [FieldOffset(0)]
        public UInt16 dVal;

        [FieldOffset(0)]
        public int lVal;
    }

    [StructLayout(LayoutKind.Explicit, Pack = 4)]
    internal struct DBVARIANT_SUB1
    {
        [FieldOffset(0)]
        public IntPtr multiVal;

        [FieldOffset(4)]
        public UInt16 cchVal;
    }

    [StructLayout(LayoutKind.Explicit, Pack = 4)]
    internal struct DBVARIANT_SUB2
    {
        [FieldOffset(0)]
        public UInt16 cpbVal;

        [FieldOffset(2)]
        public IntPtr pbVal;
    }
[/code]

But when using, not all fields have the desired value; fields after the sVal member are garbage :(

Can you spot a problem?
Thanks in advance.

VS 2k5 ignores breakpoints [VS 2k5 ignores breakpoints]

TomasDeml — Mon, 27 Feb 2006 18:05:49 GMT

Hi!

My Visual Studio 2k5 suddenly refuses to hit breakpoints. The tooltip above them says that no symbols are loaded but the output window says the opposite. I can't hit a breakpoint in both managed and unmanaged code. I've even double checked all solution and project settings and haven't found anything improper.

Even the Debugger.Break() method call does not break into the debugger...

I've tried to clean or rebuild the solution but nothing helpes...

Do you have any ideas?

Thanks a lot.

EDIT: Seems that other projects can be debugged correctly, weird...

Is here anybody who owns the Panasonic DMC-FZ5 camera?
Can you recommend it to me? What color do you think is better, black or silver? I like the silver one but most people prefer black (it even makes cameras more expensive)...

I've finished my first CP article and just want to ask you what do you think about it and the project - Parser Schemas.

There may (I think there will) be some language mistakes in the article hence tolerate them, please :).

Thanks.
