    - PropertyGrid Cloning objects I have a TypeConverter that returns a set of standard values to display a dropdown list of objects of type B for a property of type A. It appears that the PropertyGrid in 2.0 is cloning objects when setting the property for multiple SelectedObjects. In prior levels I was able to get multiple objects of type A to reference the same object of type B via a set in the propertygrid. Is there some way I can do this in 2.0 without implementing ICloneable for class B and making Clone() return this Tag: Visual C# General Dialogs Cause Program to Freeze Visual C#

    - Type Reference and Object Name IAddress KK = new MyClass ( ); Hi, my questions relate to the code above. This line of code creates a new object called KK from the class called MyClass which is defined in another file. I am trying to work out what each element from the code actually mean. Here is my understanding of the elements, please correct me if I am wrong: 1. KK is the name of the object of MyClass. The name KK is used to call methods defined in MyClass. For example KK.DoSomething ( ) 2. new is the keyword used to allocate a space off the managed heap for storing the object KK. 3. MyClass ( ) is the constructor method for initializing the field values of the class MyClass. 4. IAddress is an interface but in this case some authors would call it a ‘reference’, ‘type reference’ or ‘reference type’ for the KK object. What exactly is the ‘technical term’ for IAddress in this instance, is it simply a variable type declaration Is this the same as declaring a string or integer type object or variable Does CLR track object KK through IAddress which is the object type reference for KK Does CLR need to find the location of IAddress before it can locate the object KK which is stored on the managed heap Is it correct to say that IAddress in this case have no use other than helping the CLR to track the location of the object KK Also what I don’t really understand is, if the object KK is identified as an instance of the class called MyClass (since the constructor must have the same name as the class it initializes), why does KK need another ‘type reference’ to identify its location on the memory And isn’t class already a ‘type’ as well I have read several articles and forum posts that have attempted to answer something similar to what I am asking. But I find that the explanations are either too brief (perhaps these concepts are already clear to most programmers out there that they don’t need any further clarifications), or that the terms used by some of these authors are confusing to the reader. By confusing I mean, some authors would call both KK and IAddress ‘reference’ but at the same time use KK as a name for the concrete object. So which name is the reference of what Any attempt to help would be greatly appreciated !! Tag: Visual C# General Dialogs Cause Program to Freeze Visual C#

    - is my code leaking memory? I am running an application, and after a long period of time, it slows down significantly and I am not sure what is causing it. After reading several discussions, I have come to the realization that I might be leaking memory without knowing it. I am running a main application, and there is a thread that is running at an average of 10 times/second performing some task. Do I leak memory every time I call the "new thread" or the garbage collector will clean the thread every time it is dies Thanks! // my thread definition public void ComputeAverage() { // do averaging on an array and store avg in a variable Thread .Sleep(100); //This is done so I can obtain around 10 averages/second } public void timer1_tick( object sender, System. EventArgs e) { timer1.Enabled = false ; if (avgThread == null || avgThread.IsAlive == false ) { // make sure the array list doesn't grow infinitally if (myArrayList.Count => 100) myArrayList.Clear(); // add a new value to the array myArrayList.Add( /*I will add a random number between 1 and 100 */ ); avgThread = new Thread ( new ThreadStart( ComputeAverage)); avgThread.Start(); } // do more work. // enable timer timer1.Enabled = true ; } Tag: Visual C# General Dialogs Cause Program to Freeze Visual C#

    - Visual Studio Set References Copy Local to True Hi, I have a solution which contains many dll and exe. I set the Copy Local properties to each of References of all projects (it depends, some must be true, and some must be false). I build and save the solution, everything is in the right place. The csproj files seem to be good with <Private>False</Private> or <Private>True</Private> in every section. If I close VS and re-open my solution, all References are set to true, despite the value of the csproj. I don't understand what happens, and this is very unconvenient, because I have to re-set Copy Local in each Reference manually. My collegue, who works on the same VSS base, don't have the problem. I have not VS SP1 installed, but I have not seen any improvment in that way. Thanks for any help or suggestion. Tag: Visual C# General Dialogs Cause Program to Freeze Visual C#

    - 2D Drawing Options I'm developing an app that can graph signals (audio, FFTs, etc). Right now I'm using GDI+ and the signal is represented as a series of lines in a GraphicsPath object. I usually draw the lines then fill the path with a gradient. I'm wondering if there are any other options for doing this in C#. I thought about managed DirectX, but it seems that is mostly geared towards 3D drawing. Anyone have suggestions about a better way to go. It's important for me to draw/redraw as quickly as possible.

    - % Operator Here's what I'm trying to acheive. I need to have a condition in an if statement so that it occurs only if the value is divisible by 100. Here's a code snippet of what I'm working with: if (value < 1200 && " ") { _departmentID = value; _rules.MaintainRule("department", false); PropertyColors["department"] = Color.Black; } The condition will be going in place of the quotes. I know it has something to do with % operator but cannot figure out what I need to do. The reasoning is that I only want the if statement to be true if the departmentID is less than 1200 and divisible by 100. Tag: Visual C# General Dialogs Cause Program to Freeze Visual C#

    - Enum.Equals vs == Hi, I have another newbie question. I was looking at documentation for the ' Enum.Equals() ' method at the msdn2 website, Enum , and I was wondering what is the difference between using something like; enum Mammals { Cat, Dog, Horse, Dolphin }; Mammals myPet = Mammals.Cat; Mammals yourPet = Mammals.Dog; if (myPet.Equals(yourPet)) { } // and this statement if (myPet == yourPet) { } Does one method have an advantage over the other At the msdn2 website they don't even mention "==" in the documentation.

    - How to have multiple sets of application settings? Hi, I'm using the standard mechanism to set and retrieve application settings (using app.config, Settings.settings and Settings.Designer.cs). I can set the application settings using the Visual Studio IDE and retrieve them like this: string title = Properties. Settings .Default.WindowTitle; This works fine - for a single set of settings. But now I'd like to run multiple instances of my application, pass them an argument that makes them unique (1, 2, 3, or "master", "slave"), and use that argument to access a specific set of settings. Preferable something like: string title = Properties. Settings .Master.WindowTitle; or string title = Properties. Settings["Master"] .WindowTitle; Is this possible The presense of the "Default" instance gives me the idea that it's possible to have other instances. Thanks very much for any help.

loffing.4

I'm in the process of building a C# program. It uses a ColorDialog and a couple MessageBox.Show's. These dialogs have been working fine for a few days. Now however, whenever one of these dialogs should be displayed, the dialog never comes up and the program just freezes. This happens in both debugging and normal modes.

I know this description is pretty general, but I was just wondering if anyone had come across this before.

Hi,

any multithreaded programming at all in your code

Mark.

Does it say [STAThread] or [MTAThread] next you your program's Main() method

I think it needs to be [STAThread] if you use a ColorDialog in your program.

My program's main method has [STAThread] next to it.

Also, there is some multi-threading in my program. The program is an OpenGL worldbuilder. It's a lab assignment for a class and the instructor provided a camera class that he said was multi-threaded. I don't really know much about how it's written.
