Hi all,
OK, desperate now - I've been on this for days...
I have a large native C++ mobile project I have just migrated from eVC++ to Visual Studio 2005.
I need to integrate Intermec's RFID library into the project but they only have a managed .NET assembly available.
Is there some way I can 'talk' to this code? Can I create a C# project, incorporate the Intermec stuff, create some entry points and access them, dll style?
I was thinking of migrating my project to managed C++ but it seems this is not available in the Compact Framework.
Any suggestions would be much appreciated.
Regards
Jason

do you have clr enabled?
If yes, gcroot is you friend. It will allow you to point to a c# dll that you can add to you project.

I want do create a modeless (non-modal) Dialog. I have tryed this with ShowDailog(), but this ist modal.
How can I create a modeless Dialog?

use Show() instead of ShowDialog().

Yes I know!
The Problem is that the modeless Dailog gets no resources, when the parent dialog is still working:
When I make the following code on the parent dialog, with an endless loop I can not use the modeless dailog. All resources are on the parent dialog
void OnClick()
{
CDia dia*=new CDia();
dia->Show();
do{
// Do some Code
}while(1);
}

Hi,

for proper GUI operation you must limit the amount of work executed on the GUI thread.
If you keep it down to a few dozen milliseconds, the GUI will remain responsive on all
Forms that are visible thru Show() unless there is a ShowDialog() called somewhere.
Hence move your long "do some code" to a separate thread, and let the GUI live.

Use more than just "help please" in your subject line. It is incredibly vague.
As far as your request, it is beyond the scope of a reply.

for some reason the Encoding::ASCII->GetString always returns an empty string. While i was debugging it i verified that the buffer was full with data. in the client, i used this same method to return the string and it returned the data in the buffer (as expected). I'm not sure what i'm doing wrong here 
StringBuilder ^sb = gcnew StringBuilder();
NetworkStream ^stream = (NetworkStream^)result->AsyncState;
stream->EndRead(result);
array<Byte> ^buffer = gcnew array<Byte>(1024);
while(stream->DataAvailable) {
int nRead = stream->Read(buffer, 0, 1024);
sb->Append(Encoding::ASCII->GetString(buffer, 0, nRead));
}

all i am doing there is calling the beginread to listen for any data and when it comes just do an end read and read the data in a loop synchronously. Here is a Screenshot[^] of what i am doing here.

UPDATE:
Pretty wierd...after troubleshooting it further, i got it to work. before i sent the data on the client side, i converted it to a base64 string and on the server side the encoding function worked. what the piece of data is that i am trying to send through is a serialized object using binaryformatter. I guess the GetString function didn't like the format of the data???

What in the hell are you talking about?
Is this a .NET question? This forum is for "C++/CLI managed and mixed mode" questions as the title states, as does the top (first) post.
So far it seems you are in the wrong forum and have no idea what you are talking about, hows that working out for you?

.NET does not use the term, critical section, but uses the System.Threading.Monitor class. Also, task switching is a very low level system activity. Thus, your post is not appropriate here.

Mike is right, even if he was brusque in the delivery, you have asked in the wrong forum. This matters because this forum is a ghost town. Asking in the right forum will help you get an answer.
