In addition to what Alex Said, also make sure the assembly you are trying to debug actually what you are debugging. The assembly Debug Mode (in the project properties -> Configuration Properties -> Debugging -> Debug Mode) needs to be set to the 'Wait to attach to an external process' option. , The 'Start Application' should be the name of the 'caller' .exe. If the assembly is in the same solution as the 'caller', then it needs to be the active project in the solution.
You should also try to make sure that the assembly you are debugging is only running in a single thread (ie. the 'caller' has only instantiated one instance of the class within the assembly) for testing purposes. Otherwise you'll find that the breakpoint will get hit multiple times (hitting the F10 key to step through the code will result in you ending up on your breakoint again - albeit in a different instance)
Hope this helps,
Stefan

Thanks for the aswers, but it still does not work.
I had forgotten to write:
When I call the eventshelper directly, the debugger is doing fine.
When I call the eventshelper with the eventpool, the debugger don't stopps.

I created a Web Service that has a method that takes string arrays for ex:
public void CalculateModel(string[] stringList1, string[] stringList2)
{
//code here
}
When I add this web service as a web reference to my C++ application it generates a proxy class, in the proxy class it displays the array parameters like this:
BSTR* stringList1, int __stringList1_nSizeIs,
BSTR* stringList2, int __stringList2_nSizeIs,
Then it does the following: checks these pointers for NULL
if ( stringList1 == NULL )
return E_POINTER;
if ( stringList2 == NULL )
return E_POINTER;
So my question is how do I prevent the proxy file from adding these checks for NULL? because I do allow the user to pass in an empty string array which is defaulted to NULL on the C++ side.
Thanks

A check for NULL isn't going to hurt you, is it? It doesn't look like the wsdl.exe tool has an option like this.

Yes, it does effect me the check for NULL because it returns if the array is NULL & does not continue processing the data.

Hi,
I have a timer that I want to run in the main frame of my windows HMI application to execute a complex operation.
I chose a System.Windows.Forms.Timer timer so that it'll run on the main application thread.
I added a tick event :
this.timerPlot.Tick += new System.EventHandler(this.timerPlot_Tick);
and the timer woks fine on calls to timerPlot.Start() and timerPlot.Enable=true.
But... when I try to start the timer from a seperate thread in the application the timer function timerPlot_Tick is never called!!!
Does anyone know the reason why a timer can not be started from a sperate thread?
Thanks.

As MSDN states: "This Windows timer is designed for a single-threaded environment where UI threads are used to perform processing. It requires that the user code have a UI message pump available and always operate from the same thread, or marshal the call onto another thread."
Use one of the other two Timer types. Here you find a short overview on timers.

Hi,
I am looking for a way to write Excel spreadsheets in a c# program without having Excel installed on the computer. Presently, the Excel sheets i create are in XML, but versions of Excel under 2002 don't support XML.
So, i am looking for articles or documentation that shows how i could do that
<pr>
Thanks!

Is the investment in time really worth the effort?
You better be sure before you tackle this... Google - "Excel File Format"[^]

There are several native functions like EnumWindows or EnumChildWindows that could be used. Take a look here to get an overview. More information on how to use the native functions in C# are provided by pinvoke.net.

The C# compiler is included in the .Net Framework - the name of the compiler executable is csc.exe (for C Sharp Compiler).

created a setup project for my comapny (windows based application) using .NET Setup and Deployment project (Setup Project). I want to change the registry enviroment variables for the current user, which I easily add in their registry editor. When I install the setup in fresh computer, its instals ok and shows the updated environment variables (Right click on my computer -> properties -> Advanced -> Environment variables) but they did not work. If i open the dos window (cmd.exe), and run "set", its did not display the updated environment. Even reboot didn't fix it. I have to manully edit those value in order to take effect, which is not acceptable at user point.
It seems like very basic feature to me, when you deploy the application, you want to change the environemnt variables. Is this a knows bug or I am missing something.
Please help me..

I have to concatenate an unknown number of byte arrays, into a large byte array.
Do you know how can i accomplish this, optimally?

performance-wise?
I guess get pointers to arrays' bases and use them (the array sizes too) with the memcpy function, accessible from C++ (i think it's in memory.h).
Simplicity?
Create a big array and copy inputs into it with the Array.Copy(Array, int, Array, int, int) method

Use a memory stream:
byte[] arr1 = new byte[] {1,2,3,4};
byte[] arr2 = new byte[] {9,8,7,6};
byte[] arrFin;
using (MemoryStream ms = new MemoryStream())
{
ms.Write(arr1, 0, arr1.Length);
ms.Write(arr2, 0, arr2.Length);
arrFin = ms.ToArray();
}

I used GetBuffer and it returned an array larger then the actual number of bytes inside (it grows by doubling the current size).
Thank you!
