Unless Palm releases a 64MB handheld, it's probable that a .NET runtime for the Palm will never happen. My m100 has only 2MB of memory, and even the largest memory capacity the I've heard of on a Palm (16MB) still wouldn't really be enough. The .NET runtime was built with C#, and the Palm documentation says upfront that you should be weary of object orientated programming due to the memory restrictions. Frankly, if you want to do OOP for the Palm, I'd suggest mobileStudio[^], which provides a fairly MFC like framework, compiles relatively small for a object orientated system, and only costs $29.95 to register (the nearest competitor is over $100).

Would anyone here be able to tell me if uploading a file from a client to a server using a webservice is possible, and of course there would be a client program contacting the webservice. Is this possible? Or would i have to fiddle with remoting etc?
|
|
|
|

I'm presuming this is for a Win32 environment and not web?
If for Win32, maybe have a look at the Stream objects as a way to move a file around.
Cheers,
Simon

Hmmm, thank you I'll check into streams.
|
|
|
|

I don't know much about web services cause I usually use remoting. But try passing the filestream to the server as a parameter.

Hope this is the right forum for this sort of question...
We've been running VC 6.0 and are considering upgrading. My boss has a dual CPU machine, and VC 6.0 doesn't take advantage of it because the compiler is not multithreaded. We were wondering if this has been address for the .NET version of the compiler. Anyone got any ideas on this?

While compiling my CPU usage goes over 50% on my dual, but not to 100%
This means that it is not multithreaded, but some tasks are being done in seperate processes. I would assume the compiler is some sort of console utility running in the background, with VS listening and echoing (which takes cycles from the tool on a single cpu).
And performance isnt the only reason to go dual!
Being able to use photoshop, browse the net, review code, etc. while vs.net does its thing is just as valuable.

Thanks for the feedback. Yeah, that's the same behavior we noted in 6.0. Oh, well...

Which is the reason, of course, that he went dual. Er, did I mention he was the boss? (In fairness, we all have screaming machines and ours, while not dual, have faster CPUs that actually build the system quicker than his. I think we got the better end of the deal.)
Thanks, man!

By Microsoft's own admission, the C# compiler is not much of an optimizer. I need to get a particular class working blazing fast, so I'm using ildasm to get the IL, modifying it and ilasm-ing it back to a PE.
I need to know what's a faster way to push two references to the current object onto the stack:
ldarg.0
ldarg.0
OR
ldarg.0
dup
Thanks

I'm going to ask a dumb question:
If you're requiring performance only, why not go for C++ (or even inline C) ?
I don't see the benefit of doing IL manually.

After disassembling the Managed C++ code, I realized that I can optimize it better than the compiler. However, the MC++ included some native code which can't be disassembled with ildasm so I can't compile it with ilasm. Besides, since the stuff is managed, it doesn't really matter what language I write in; I like C#.
|
|
|
|
|
I think it does. Only memmory is managed, but the Managed C++ code is more optimized that C#, actually I think is the only optimized language from .NET. Also with managed you can combine managed and unmanaged code so you can obtain native code for real time actions.

Could you direct me to where ms says mc++ is more optimized?
I cant seem to find reference to that.

The 2nd part is faster since dup doesn't need to be verified and it's considered type safe

And since you are interested in Il, check the Ecma-335 specificationthat deals with the Commom Language Infrastructure, in which IL instruction set belongs, here Common Language Infrastructure

I don't think there will be any observable difference between the two. I will really be surprised if your hand optimization gives you more speed than the unoptimized code.

Excuse my (!knowledge ) of WebServices.
Let's say I have a simple WebService that accepts 2 integers and give you back the result of addition.
What's the way to make this service known to other applications. Do you need to setup some central server, so it would keep track of all services (let's say in an Intranet), or is there a standard way to do it ?
Thanks
Venet.

Hi Venet
Have a look at UDDI.
If you're doing this more for a test, then maybe link your webservice from XMethods.

I've extended the TreeNode control to add an additional property. Now, what
I'd like to do is capture the MouseDown event so I can perform some tasks
when either the left or right mouse button is clicked. However, I can see
that the TreeNode doesn't have any events to override. I tried capturing it
with the TreeView control, but can't get the underlying object that was
clicked.
Any ideas? I was thinking about creating my own custom event in my extended
control (TreeNodeExID)... but I can't find any examples or documentation...

Override the WndProc procedure and handle the Windows Message WM_LBUTTONDOWN:
class TreeNodeExID : TreeNode
{
...
public const int WM_LBUTTONDOWN = 0x0201;
protected override void WndProc(ref Message m)
{
if(m.Msg == WM_LBUTTONDOWN)
{
}
base.WndProc(ref m);
}
}

How can I fill ( or create ) a Enum using DB records as items ??
Or How can I override a enum declaration ?
( I want to add items to an Enum declarated in other class )

This may be possible by progmatically writing code and then using Emit() to generate a runtime assembly, and then using that code.
But really, you shouldnt add so much complication. Better to keep the records in their native format.

Agreed.
It might also be an option to check out Typed Datasets.
