To be exact, functions are stand-alone procedures while methods are procedures that belong to an entity (class, struct, etc.). It's not just a .NET term but a procedural vs. object-oriented naming convention.
I've done some searching but can't seem to find what I'm looking for. I have a solution with roughly 30 projects (all C#) in it. Fairly often, perhaps every 5th or 10th debug build, I get errors in 1 to 3 of the projects that say that the /debug/obj/<projectname>.pdb file is in use and the build couldn't complete. I cannot delete the file without shutting down VS, but once I do and restart, the projects build fine. In using VS.NET 2003 on W2K. Is there something causing this in what I'm doing? Is it an IDE bug? How can I fix it or efficiently circumvent it? I realize that this may not neatly fit into the C# newsgroup topic, but it seemed the best match. Any help would be greatly appreciated. Thanks!
More info. This happens with code behind a Windows Form. When this problem arises, close all of the Windows Forms documents in the IDE and the file is released by whatever is holding it. Seems like a bug...
Thanks for the reply, but I don't have FXCop and the above seems to negate 'a'. I'm puzzled.

I am working on a Windows application in C#. I have to develop a component which can display the text in multiple languages like Sapnish,Russian,French. I just started looking into it and one way I found is using the resource file somehow. But I create my component runtime by reading a XML, and all the contents are shown in grid. So I think I cant use the resource file way.
Another way is by using the unicode, but I couldnt figure out how to use it. Any help will be highly appreciated.
You don't reall use Unicode, per se. Strings are either ASCII or Unicode. In .NET and Java, all strings are natively Unicode. You really only have to worry about this when marshaling strings to native calls or with stream encodings.
If you're creating your component at runtime using an XML file, when you read the values of properties use the TypeDescriptor to get the PropertyDescriptor or use reflection to see if the property is attributed with the LocalizableAttribute and the value is true. If so, use an instance of a ResourceManager that specifies a Type (this doesn't have to be the Type of the component you're essentially deserializing) and use GetObject to read the information from the resources file.
I know this is probably really stupid, but I am looking for a way to reference a control from a class. If I change the control from 'private' to 'public static', I have no problem using the control. Except that I have to change all the reference from this.myControl to myForm.myControl.
When I switch back and forth between code and design view, the IDE will remove all of my changes.
Can anyone lend a quick helping hand. Thanx In Advance
If this is an instance of a control, you shouldn't access it from a static. Just have an public instance property that returns the control from the instance of that class. It would be much better, though, if you only expose what you need from that class. This is known as data-hiding - you don't want to expose too much information or allow unverified code to change the behavior of your class. If you want the property to only be visible in your assembly, use the internal access modifier instead of public.
A control and a window are distinct window classes with different window styles. Instead of having to modify window styles and going to the work of implementing a pump, simply host the control in a borderless form and return the dialog result from the form:
publicstatic DialogResult Load(MyFakeWindow window)
Form f = new Form();
f.FormBorderStyle = FormBorderStyle.None;
window.Dock = DockStyle.Fill;
DialogResult result = f.ShowDialog();
I was wonder if anyone ran into this problem before, if so could help me. I am trying to insert data into a database from a textbox. Once the user enters the data and presses the add button the database sould be updated and move to the next record. My problem is when the user presses add,I get the following error:
An unhandled exception of the type 'System.Data.SqlClient.SqlException occurred in system.data.dll
The code is as follows.........Thanks in advance!!!!!!!
If you're filling a DataSet with a SqlDataAdapter, may I also assume that you're binding it to your controls? In this case, just call SqlDataAdapter.Update passing the changed DataSet (the adapter will get the changes and execute the appropriate SqlCommand for the type of change, then will accept the changes on the DataSet). This very easy. To move to the next record, get the CurrencyManager for the bindings (see Control.BindingContext for more information) and increment or decrement CurrencyManager.Position to move forward or back respectively (check the curren position for 0 or Count - 1 before setting it, though, or an exception will be thrown for extending beyond the range of data).
missed dot must have caused compile time error so sth different occured.. I think you din't use right order to get access data in db. I mean you may not define sth properly such as a dataset.. We could not see the whole code. Good luck.
Is there any way to handle tcp syn packets without setting SIO_RCVALL socket options ?
The following works with icmp and udp msg but not with tcp connection requests.
System.Net.Sockets.Socket srv_socket=new System.Net.Sockets.Socket(System.Net.Sockets.AddressFamily.InterNetwork,System.Net.Sockets.SocketType.Raw, System.Net.Sockets.ProtocolType.IP);
new System.Net.IPEndPoint(System.Net.IPAddress.Parse("127.0.0.1"), 2000)//whatever you want
srv_socket.Receive(ReceiveBuffer);// handles udp and icmp message but no tcp syn
Just about everybody will have seen or used this functionality I am trying to replicate, most likely in Acrobat viewer - or a variant which is [CTRL + Cursor] in most scrollable windows.
I am working on a simple image viewer, that overrides the onPaint for the form and renders a given image directly onto it (i.e. no picture boxes etc). Image display is working as it should but I am now looking for a way to scroll the form using mouse events. For example, the user clicks and holds on the form, when they move the mouse pointer the form is scrolled in the direction of mouse travel.
The mouse events to do this are relatively simple :
