Web Forms: Child form __gc Array

• nurbynerd / 100 / Sun, 05 Apr 2009 11:54:00 GMT / Comments (6)
• Hi,

  I have a VC++ .Net 2003 MDI application.

  I am declaring a __gc Array in the frmChild_load method of the child form. The declaration is as follows

  Double zData __gc[,] = new Double __gc[10,10];

  It compiles and links properly but I get the following run-time error!!!!!

  Error: Method not found: Void System.Array. (System.EventHandler)

  The same declaration of array in the Parent form load method does not give any error

  Please let me know if i am missing something ar the array has to be initialized in some other way

  TIA

  Suneet

• 1. Anybody?

     The 2dimensional __gc array doesnt seem to be working in any child forms

  2. The error message doesn't look like a method at all. Can you double-check the exact wording of the message please?

  3. Hi,

     These were the exact words I got on the error message. I have uploaded the screenshot of the error at this link

     http://grove.ufl.edu/~suneetl/CPP%20Program/Error.jpg

     and for reference, I have uploaded the sample project at following location

     http://grove.ufl.edu/~suneetl/CPP%20Program/ZTest.zip

     Please let me know if there is something that I am missing.

     The error disappears when I comment out the array declaration line

     TIA

  4. I

     poked at your code for a while, using VS2003, SP1. There's

     something really strange going on. I isolated the statement in a

     test() function. The first thing that was weird is that I

     couldn't get a disassembly for the function in the IDE. Next, I

     looked at the IL:

     .method private instance void test() cil managed

     {

     // Code size 27 (0x1b)

     .maxstack 2

     .locals init ([0] int32[,] V_0,

     [1] int32 i,

     [2] int32[,] ia,

     [3] int32 j)

     IL_0000: ldnull

     IL_0001: stloc.2

     IL_0002: ldc.i4.s 10

     IL_0004: ldc.i4.s 20

     IL_0006: newobj instance void

     [mscorlib]System.Array::$MR$16(class [mscorlib]System.EventHandler)

     IL_000b: stloc.0

     IL_000c: ldloc.0

     IL_000d: call instance void [mscorlib]System.Array::Initialize()

     IL_0012: ldloc.0

     IL_0013: stloc.2

     IL_0014: ldc.i4.2

     IL_0015: stloc.1

     IL_0016: ldloc.1

     IL_0017: ldc.i4.2

     IL_0018: mul

     IL_0019: stloc.3

     IL_001a: ret

     } // end of method frmChild::test

     Huh, System.Array::$MR$16? Doing something with

     System.EventHandler? I just have no idea why this kind of code is

     being generated. I'm going to punt and say you are suffering from

     a compiler bug. Call Microsoft Support to get a workaround for

     this. You've got a good diagnostic here. They'll charge

     your creditcard but you'll get it back when they conclude this is a

     MSFT bug, not yours. It isn't yours.

  6. Got a work around from MS Support, but the issue has been registered as a bug and they are trying to fix the same.

     thanks again for the inputs.
