You don't want links, but you should maybe do some
research into Serialization[^].

I doing this project that i have no idea in my mind at all. U guy out whoever pls help me..Thax alot.. get back to me asap Thax alot=)
The router n parents are all button. Once the sever click at the router, it will than show it deter how many parent it have or link and when the sever click at the parent is will show how many children the parent link to or have and it detail of it also like temperature, terminal ID and other. The symbol for the children is a circle. We need to connection them with arrow shown. It just like a family tree from router link to parent and from parent it show how many children it have. We need to use Visual studio 2005 and C# to create own button n image. This project is like a piece of empty sheet of paper/form and our duty is to draw family tree on it.

Hi,
This seems to be a 2D drawing related project, therefore, the best thing I could suggest you to is to use Drawing classes of .Net framework.
Please take a look at the following article which shows how to drawing classes of .Net framework.

Hope this helps  .

Hi,
This seems to be a 2D drawing project. The best thing I can suggest you to go throuhg the Drawing Classes of .Net framework (i.e, their methods, properties etc.) which can help you to draw the drawing ojects on the canvas.
Take a look at the following article, this might help you in understaing the capabilities of drawing classes of .Net.

Hi i am writing a C# class library which i want to use in my VB Client
So i wrote class like this
[Guid("0AA209CD-D713-4336-8804-F7D4888F58BD")]
[InterfaceType(ComInterfaceType.InterfaceIsIUnknown )]
[ComVisible(true)]
public interface IClass1
{
void Temp1([MarshalAs(UnmanagedType.LPArray, ArraySubType=UnmanagedType.LPStr )] String[] IDs,int size);
}
[Guid("CCDAD140-DD55-4047-A925-A1B539396A01")]
[ComVisible(true)]
[ProgId("CommonCatalogue.Class1")]
public class Class1:IClass1
{
public void Temp1([MarshalAs(UnmanagedType.LPArray, ArraySubType = UnmanagedType.LPStr)] String[] IDs, int size)
{
string TempDate = "dfdf";
}
}
but when i referenced this library (.tlb) in VB the temp method singnature coming as
Temp1(IDs As String, size As Long)
i am unable to fix this. Please can any one help me in figuring out this.

Thanks for the response.
Ya using ref in the method's declaration of C# we can get the correct syntax in VB but is there any other way which does not require any ref in the method declaration.

Hello!
My name is Alla. I'w working as a programmer in New Hampshire. I've just started doing Word and Powerpoint Automation (never done before Office Automation). The application I'm working on now creates document-packages,containing one or more Word documents and export these documents to particular locations.
I created Word Application Instance only once at the beginning, so I use this Instance for all documents that I'm going to create for exporting. Everything was fine so far, but when I'm trying to export a huge amount of documents,the following error appears - RPC SERVER UNAVAILABLE and any reference to existing Word Instance throws an error ( it happens when during processing some documents for some reason Range.Paste method throws an exception (RPC server failed)., then I get MS Word warning message and Word trying to recover documents. Immediately after that I get RPC SERVER UNAVAILABLE - means that any access to my Word Instance fails. May be it makes sense to create many Word Application Instances for each document, but we have problem with performance.I tried to send this question to microsoft forums, but nobody responded..Could you, please, help me to solve this problem?
Thank you very much in advance and best regards.
Alla

Hi,
I'm not very knowledgeable on threading...
I'm using Invoke to receive Serial Port data. The form locks when I try and call "this.Close()". Do I have to remove/stop the Invoke thread before using "this.Close()" to automatically close the form?
private void serialPort1_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
{
serialPortData = serialPort1.ReadExisting();
this.Invoke(new EventHandler(SerialPortEvent));
}
thanks,
Ron

If you have any active threads, it good to stop them while you close the form. You can do this in the Dispose method of your form.

Thanks Navaneeth,
What code would I use to stop an "this.Invoke()" thread?
Ron
|
|
|
|
|
If you use myThread.IsBackground = true; the thread will close automatically after this.Close()

Hi Mo,
I'm using "this.Invoke()". Should I be using a different type of thread? If not, how do I stop "this.Invoke()"?
Ron

Hey Ron.
I'm using IsBackground property for closing Thread with closing form.

I don't know exactly.

Control.Invoke puts a serialised delegate onto the windows message loop.
How much work are you doing in your SerialPortEvent method? If you are doing enough work to block the UI up then you are probably blocking the serial library as well.
Consider taking data in the DataRecieved event, placing it on a queue, and perhaps Monitor.Pulse a background thread and returning out the event handler immediately to return control to the serial port code. Then your background thread can consume the data events that are on the queue, and process them. Then when you want to make UI changes, you either use Form.Invoke, or .BeginInvoke to make the required changes.

Thanks Mark,
The SerialPortEvent calls on a Method to parse the c/c swipe data. Is Method run through the Invoke thread, or the main thread?
private void SerialPortEvent(object sender, EventArgs e)
{
SwipeMethod(serialPortData);
}
Also, if I use ShowDialog() (instead of Show()) to open the Form, there is no issue with using this.Close().
Ron

SerialPortEvent is executed on the UI thread. So SwipeMethod will run on that same thread.
Not sure on the ShowDialog vs Show deal... but I haven't had very much coffee today 
My worker thread/queue setup was based on the assumption you were processing bunches of data from a serial port. If you are popping a form with "Swipe CC now" then it might be worth looking at just using Delegate.BeginInvoke and IAsyncResult. This will use a thread from the pool.

Yes, I've been playing around some. I'm not sure if it's a bug in .NET 2.0. After the transaction is approved, I want to exit the Form with "this.Close()" but it locks the app. If I switch to BeginInvoke it works ok. Also, I can use Invoke, if I open the form with ShowDialog instead of Show.
