I want to put my referenced assemblies in a subfolder of \bin .. like \bin\assemblies. My application is in \bin.
By fefault .NET puts my app/assembly in same folder as my referenced assemblies. i use "Local Copy" of all references.
Is there a way to tell .NEt to use other locations?

You may try using config file for that.

 I'm using THE api(SendMessage or PostMessage) to send a custom message between 2 C# exe's. The called exe is subclassed to listen to the custom message. In the calling exe, I'm trying to pass a string in the 4th parameter. At this stage the 2nd exe is already running. The api call keeps crashing the 2nd exe. Can it be done across exe's or only within the same exe, thanks.
thanks for your apply or provide sample code( the best  )

Using SendMessage API to control external app:
have an external application that I need to be able to control. I've tried using SendKeys but due to the obvious limitations of this function the behavior is erratic. I know you can do this using the SendMessage API ( find the handle of the external application's window ，first ) ,but I'm not sure how to do it.
can you provide the sameple code to me ,please?

By trying using SendMessage API i got:
C:\Projecti\test\Form1.cs(77): 'System.Windows.Forms.Control.SendMessage(int, int, int)' is inaccessible due to its protection level
This API is from Platform SDK and i think it doesn't support in C#.
To get handle, you can call GetActiveWindow or FindWindow

I can do it now
I can use FindWindow,GetWindow and SendMessage to send message to a notepad app,just like this:
hWnd1 = FindWindow(null, "Untitled - Notepad");
hWnd2 = GetWindow(hWnd1, GW_CHILD);
sText =this.textBox1.Text;
SendMessage (hWnd2, WM_SETTEXT,sText.Length, sText);
but I don't know how to excute a word app's dictate by another app,help me please ,thank you!

I'm learning to program in C# w/ VisualStudio.NET 2003.
I've just bought a MCAD Certification book (70-316) Kalani.
Just started reading the self-assesment portion:
Here's some questions...
What the heck is the difference between the Framework SDK and VisualStudio.NET??
How do I "practice" working with the Framework SDK, as suggested in the book??
I know I'll get hammered for this Q. but so what...would I know the difference just by looking at the screen?
--thanks

The Framework SDK can be downloaded without buying VS.NET. It comprises everything you need to write programs in C# using a text editor and the command line, or a third party IDE, of which one or two exist ( free ware ).

Write code.

The study guide said make sure you practice with BOTH VS.Net and
The Framework SDK.

OK, then I did answer that, and rgraham explained it in more depth than I did.

Visual Studio NET is an Integrated Development Environment - an environment that supports creating applications by providing graphical tools, debugging facilities, project management tools etc.
The NET framework is a family of classes that provide libraries of functions that provide the foundation of the programs you create using NET languages.
The NET framework is an integral part of any application you create. Visual Studio is an environment that assists you in creating those applications.

Example in psudocode
new myHugeObject HugeObject();
.....
myHugeObject = null; //no GC between this statement and the next
fixed int i;
//CLR calls garbage collection here
In this case will any more memory actually be made available to the application (would require a c/c++ style linked list style heap), or will all the memory freed from MyHugeObject and any other GCed variables be unavailable until i goes out of scope?
I'm assuming it would be the latter, in which case prior to allocating fixed variables with long lifetimes might be one of the handful of exceptions to the general rule against forcing manual GCs.

The CLR uses a special large object heap to handle large objects, so doing a collection probably wouldn't have the effect you are expecting.

Forgot about that. I'm more interested in the behavior of the GC itself than in a particular circumstance that would cause it though. modified example.
//allocate lots of small-medium sized objects, and release them all at once (ie stuff them into a container, etc)
fixed int i;
//CLR calls garbage collection here
If the CLR is smart enough to do a GC before creating fixed variables this wouldn't matter, but if the freed objects were around long enough to become Gen2 and needed finalizing there'd be a major performance hit in a potentially unneeded call, so I doubt it would.

In your example, you're creating an int32 after you allocate and release a large number of objects. AFAIK, in the IL code thats generated, the space for the int32 value type is allocated at the beginning of the method its declared in, not when your code specifies its creation, I THINK! I haven't verified this with a test though...
If this is indeed the case, your question isn't valid because it describes a situation that never happens.

I'm not sure how it would affect it. Probably the best way to figure it out is to fire up windbg and sos to see where all the allocations are.

I don't think having fixed variables affects collection of other objects. The GC walks the heap and traces roots to those objects. In your case, if the GC happened at the point you indicated, then it will notice that HugeObject has no outstanding references and hence will garbage collect it.

You've misunderstood my question. My concern was that the fixed variable would be placed after HugeObject in memory. Since the fixedvar can't be moved, freeing HugeObject wouldn't actaully provide any more memory to be used without the memory manager using a freelist type structure to allocate memory in the space between the nonGCed objects and the fixedvar.

No, it wouldn't. HugeObject would end up on the Large Object Heap. Your int would not be allocated on the same heap.
Also, fixed can only allocate pointers. You can't use it to allocate an int, but you can use it to allocate a pointer to an int. In order for the pointer to be valid, the fixed statement pins the target of the pointer so the GC can't move it. Once the fixed statement is no longer in scope, the pinned object is released.
Point pt = new Point();
fixed ( int* p = &pt.x )
{
*p = 1;
}

In client and server environment. My client make a request to the server, then server need to create a new Appdomain object "ad", then create an object "so" from this new Appdomain for client to use, My questions are:
(1)How to create a new channel and register this server object "so" in the new domain, I went through all the Appdomain class members, still don't have a clue.
I am thinking to use "ChannelServices.RegisterChannel(new IpcChannel(portName))", but how to associate this to new Appdomain object "ad" or "ad" event(I am guessing)?
(2)If (1) succeed, how I let my client know or pass the reference of new registered object to the client since client won't be able to know the channel information in advance?
You help is highly appreciated!

That's about US$1,104 a year. It sounds like you're worth it.

You sound like a real candidate for www.rentacoder.com. They get people with little skill in the third world, and pay them badly, to write bad code. You should check it out.

I've developed a simple C# program (for PocketPC), and It sometimes crashes with an unhandled exception... and I thing it is related to UI matters. The message is this:
Exception
Application::Run+0xf
Form1::Main+0xa
Mi application read info from serial port (from a GPS), with this event handler:
private void OnDataReceived(object sender, SerialDataReceivedEventArgs e) <br />
{ <br />
while(port != null && port.BytesToRead > 0) <br />
{ <br />
int Cnt = port.Read(portBuf, portPos, 1); <br />
<br />
if (Cnt != 0) <br />
{ <br />
if (portBuf[portPos] == '\n') <br />
{ <br />
string sentence = Encoding.ASCII.GetString(portBuf, 0, portPos-1); <br />
AddResult(sentence); <br />
<br />
portPos = 0; <br />
} <br />
else <br />
{ <br />
portPos++; <br />
} <br />
} <br />
}
} <br />
<br />
After much investigation, now I am able to cause that exception by clicking a button. The code is this, simple one:
<br />
private void btnClosePort_Click(object sender, System.EventArgs e) <br />
{ <br />
Cursor.Current = Cursors.WaitCursor; <br />
<br />
Thread.Sleep(1000); <br />
<br />
try <br />
{ <br />
port.DataReceived -= new SerialDataReceivedEventHandler(OnDataReceived); <br />
Thread.Sleep(1000); <br />
<br />
port.Close(); <br />
port.Dispose(); <br />
port = null; <br />
} <br />
catch (Exception ex) <br />
{ <br />
AddResult("-->Failure"); <br />
AddResult(ex.ToString()); <br />
} <br />
<br />
Cursor.Current = Cursors.Default; <br />
<br />
AddResult("-->Closed"); <br />
}<br />
Notes: AddResult simple does add strings into a ListBox.
The really strange thing is this: if I remove the AddResult(sentence) call in "OnDataReceive", the exception is not thrown.
Could it be any bug related to UI ?

Hope you can help me 
Thanks to all!
