c#-2.0

I have two C#.net projects project 1 and project 2 (names changed) in single solution. I am using Visual Studio 2005. I have added reference of project 2 in project 1 by right clicking and choosing 'Add Reference'. Both projects are of 'Application' project type not Class library type. I have some classes in project 2 which I want to access in project 1. After adding reference I tried to use import namespace of project 2 in project 1 but I guess its not available. Visual studio Intelisense is not showing me the desired namespace. Can anyone please suggest about how to access namespace and

I have a ComboBox with AutoCompleteMode = suggest and handle the KeyPress event like so: private void searchBox_KeyPress(object sender, KeyPressEventArgs e) { if (e.KeyChar == (char)Keys.Return) { // do stuff } } However, it does not catch the Enter key. It catches everything else since the autocomplete dropdown works perfectly. I also tried the suggestion offered here : http://social.msdn.microsoft.com/Forums/en-US/netfxbcl/thread/2db0b540-756a-4a4f-9371-adbb92409806 , set the form's KeyPreview property to true and put a breakpoint in the form's KeyPress event handler: private void Form

There is probably a really straightforward answer to this but I'm having difficulty finding it. Simple, I have a TreeNode and I would like to make its visibility false. (or another way of not allowing it to be shown until required). Edit - Another Question? I'm confused as to how there isn't a Visible attribute but then there is the property: Node.PrevVisibleNode; What is the difference between this and Node.PrevNode ? Thanks, I don't think you can do that. There is an IsVisible property, but it is readonly and will indicate whether the node is currently visible within the client area of the

I would like to call a sql statement such as: Select * From Table Where Column in ('value1', 'value2', 'value3') Is it as simple as setting a command parameter's value equal to " ('value1', 'value2', 'value3') "? David @Charles: You're going into the right direction, but we're using parametrized queries to mainly prevent SQL injections. Putting 'external' values ( params string[] args ) hardcoded in queries is asking for trouble. You can iterate the arguments, but you still have to use parameters like this: string[] values = new [] {"value1", "value2", "value3", "value4"}; StringBuilder query

I using List<T> in my project, this list contains hundreds of entries. I am using List.Contains method quite a lot and this is hurting performance, I replaced the List with dictionary but it resulted in memory bottleneck, thus made performance even worst. Is there a better solution that one can suggest for searching in List? Is there a replacement of HashSet<T> in C# 2.0 or some other way that is better both memory and speed wise? A Dictionary<T,bool> can be used in place of a HashSet<T> . Whether you add items with a value of True or False is a coin toss, the value is not relevant. It's more

I've got a base class: public abstract class StuffBase { public abstract void DoSomething(); } And two derived classes public class Stuff1 : StuffBase { public void DoSomething() { Console.WriteLine("Stuff 1 did something cool!"); } public Stuff1() { Console.WriteLine("New stuff 1 reporting for duty!"); } } public class Stuff2 : StuffBase { public void DoSomething() { Console.WriteLine("Stuff 2 did something cool!"); } public Stuff1() { Console.WriteLine("New stuff 2 reporting for duty!"); } } Okay, now say I've got a list of items: var items = new List<StuffBase>(); items.Add(new Stuff1());

i wanna save a picture that loaded in a picturebox to stream .when i save in png format it work properly but when i want save it in other formats i get A Generic error occured in GDI + exception its my code: Image Img = pictureBox1.Image; byte[] inputImage = new byte[Img.Width * Img.Height]; System.IO.MemoryStream ms = new System.IO.MemoryStream(); ms.Read(inputImage, 0, Img.Width * Img.Height); if (System.Drawing.Imaging.ImageFormat.Jpeg.Equals(Img.RawFormat)) { pictureBox1.Image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg); } else if (System.Drawing.Imaging.ImageFormat.Gif.Equals(Img
