may be using Win32 Old API 
it can be possible !!

I have an old Win32 legacy app. I’m able to start the process and send key presses to it (via sendmessage) from another app. What I would like to do is remove this program from the taskbar. An ideas?
setting CreateNoWindow=true; does not work
I start the process with this:
mp = new Process();
mp.StartInfo.FileName = AppPath+"\\Win32App.exe";
mp.StartInfo.WindowStyle= ProcessWindowStyle.Minimized;
mp.StartInfo.CreateNoWindow=true;
mp.Start();

Can anyone explain me what this mean? Is it related to Dispose()?

Take a look at the MSDN article "Gozer the Destructor"

So I have to implement the ~Class for my component or just override the Finalize()?

A component derived class should already implement IDispose, override Dispose() (if and only if you have unmanaged resources that need to be freed)

Here[^]) is an article that is newer than the other one, which has a nicer design pattern for handling disposing and finalizing.

Arun,
Thanks for pointing that article out. It is much better. (If fact one example in the older article will not compile w/ .NET 2003).
Thanks again.

Hello,
I'm looking for a way to get the memory adress of a C# object.
Any idea is welcome  .
Thanks,

This is specifically hidden to the user as object address change continuously due to the GC. If you debug a program with CorDbg, these addresses will be shown, but like said, unlike C/C++ they are likely to move during each garbage collection.

Hi Leppie,
I was expecting something like that. It makes totally sense. I'm now sure.

You wont believe it, but I'm stuck with this issue as well (building a VM emulating the CLR VM on top of .NET). If you are intereseted look at the ld.XXXa IL instructions. There seems to be no highlevel functions for this. Maybe something like this would work (no it wont dammit). Maybe...
load an address on stack and then return that as IntPtr, but you have to carefull...
As you can see I'm bit lost too! What I do know (think rather) is that be default GetHashCode() returns the signed addr of a non Value /String object.
I could be wrong.

Hi Leppie,
What is this crazy idea of yours to build a VM on top of the VM of .NET ?
Nevertheless, thank you for sharing with me your researches.
By the way, for your nBass project, the BASS library has just been updated to 1.8a.

This does the job perhaps:
.method private hidebysig static void*
GetAddr(object& o) cil managed
{
.maxstack 1
ldarg.0
ret
}
You need to pass a ref object, so cast the 'o' to object.

Just what you say: Crazy! But the ideas change all the time! The new idea is to have a Side by Side VM, with a different IL language (read more simplified).

Thnx, I havent worked with it for ages... maybe when I'm bored...

Actually from that previous IL method it appears that when passing any object by ref, the CLR creates a pointer that holds the object, still not what you are looking for though.

OK here is what works:
.method private hidebysig static void*
GetAddr(object& o) cil managed
{
.maxstack 1
ldarg.0
conv.u
ret
}
Output from Cordbg (after calling meth, but passing only c1, NOT ref c1):
object c1 =(0x00c41910) <testing.class1>
void* h = 0x00C41910
I cant see a way to do this via C# though.

I dont know how one would call a ref object without adding the ref keyword in C#???

Hi Leppie,
I'm amazed  !
Thank you very much for this. Coding at the IL level looks very hardcore for me . Good for you. .NET has no secret for you  .

Microsoft Word XML Content Development Kit.[^]
WordML Opens Up the Word File Format
Word 2003 can use standards internally as well as externally. When you save a Word document, one of your choices is to save it as an XML file. By default, this will use Word's own XML schema, informally called WordML. WordML is now a completely open, non-binary format that captures all of the information and formatting from a document. For the complete WordML schema, download the Microsoft Word XML Content Development Kit.
