Hi, for most (if not all) data types MaxValue+1 and MinValue have the same bit representation. If your code is not detecting overflows, incrementing MaxValue will just result in Minvalue; if your code is organized to detect overflow, an OverflowException will be thrown. :) Luc Pattyn [Forum Guidelines] [My Articles] Sorry for any delays in replying, I currently don't always get e-mail notifications.

I try to explain you my view, A wrapper class enables reusability because you add an "interface" beetween implementation code and the use of it. If it's well designed, you can change implementation and its impact on use is minimal. If not, you will have to do a lot of changes in use code.

Hi, the fundamental idea of multithreading is to perform multiple tasks in a rather asynchronous fashion, i.e. without predetermined order of execution; the goal is to make optimal use of available resources e.g. performing calculations on data as soon as such data is available. If the subjobs must be executed in a very specific order, multithreading simply makes no sense, since now the logic makes everything fully predictable. Examples of unpredictable execution could include: - some long winding calculations; - some user interaction; - a background printjob; - a database query; all of the above combined in one app. It would not make much sense to orchestrate this in a fixed manner since one never knows which subjob will take what time to execute, hence asyncrhonous execution, using several threads. In a typical application, there may well be a need to synchronize two or more threads from time to time. Several mechanisms are available for this, typically one thread waits for something (say a consumer needing some data), and another thread signals something (say a producer providing some data). Known mechanisms include: AutoResetEvent, ManualResetEvent, Queues, Semaphores, ... Joining two threads is a drastic synchronization since now one of the threads no longer runs. I would suggest you: - search and read some articles on multi-threading, here on CodeProject; - experiment with a more appropriate example. Hope this helps.

here is an example on xmlSerialization http://www.4shared.com/file/22596905/834df73f/XmlSerializationExample.html[^] good luck :)

your welcome :) have a nice day too

hi, now i've tried to create the MyData class. However, i'm stuck on how to change the codes in the form to do the serialization. below is some of the codes: MyData Class: [XmlRoot("MyData")] public class MyData { public MyData() { } public MyData(ArrayList shape, ArrayList color, ArrayList coord, ArrayList size, ArrayList gpd) { this.ShapeTypeList = shape; this.ColorList = color; this.CoordList = coord; this.SizeList = size; this.arrS = gpd; } public enum TypeOfShape { Square, Rect, Parallelogram, Trapezoid, Diamond, Triangle, RightAngleTriangle,Circle,Oval,Hexagon,Pentagon,None } // XmlSerializer serializ() // { // XmlSerializer s = new XmlSerializer( typeof(ArrayList),new Type[] {typeof(Coordinate),typeof(ColorL),typeof(SizeL), typeof(ArrSave)} ); // return s; // } XmlSerializer s = new XmlSerializer( typeof(ArrayList),new Type[] {typeof(Coordinate),typeof(ColorL),typeof(SizeL), typeof(ArrSave)} ); ArrayList ShapeTypeList=new ArrayList (); ArrayList ColorList=new ArrayList (); ArrayList CoordList=new ArrayList(); ArrayList SizeList = new ArrayList(); ArrayList arrS = new ArrayList(); ArrayList PathList =new ArrayList(); //[XmlArray("CoordinateData")] [XmlElement("Coordinate",typeof(Coordinate))] public ArrayList coordList { get{return CoordList;} set{CoordList=value;} } public class Coordinate { public Coordinate(){} public Point[] point { get{return point;} set{point=value;} } }..................... MovePosition Function in Form: private void MovePosition(int position,int BshapeNo,int sztotal,int szOrd) { if((TypeOfShape)ShapeTypeList[shapeNo]!=TypeOfShape.Circle&&(TypeOfShape)ShapeTypeList[shapeNo]!=TypeOfShape.Oval) { alDrawingObjects.Insert(position, new Polygon((Color)ColorList[shapeNo], (Point[])CoordList[shapeNo], 5,(GraphicsPath)PathList[shapeNo] )); } else if ((TypeOfShape)ShapeTypeList[shapeNo]==TypeOfShape.Circle||(TypeOfShape)ShapeTypeList[shapeNo]==TypeOfShape.Oval) { alDrawingObjects.Insert(position, new Ellipse((Color)ColorList[shapeNo],(Point[]) CoordList[shapeNo], (Size)SizeList[sizeOrder], 5) ); SizeList.Insert(sztotal,(Size)SizeList[sizeOrder]); SizeList.RemoveAt(szOrd); } CoordList.Insert(position, (Point[])CoordList[shapeNo]); ColorList.Insert(position,(Color)ColorList[shapeNo]); ShapeTypeList.Insert(position,(TypeOf

hi, After i serialize a few arraylist, my xml file seem to look like below: 1 40 18 110 18 110 68 40 68 142 256 is this an error? why does is the elements is named '' Besides, how do i deserialize arraylist of different types. first i declareas shown below:(this is declare in Form, i did not use MyData class, instead all arraylist is declared in the form) XmlSerializer s = new XmlSerializer( typeof(ArrayList),new Type[] {typeof(Coordinate),typeof(ColorL),typeof(SizeL), typeof(ArrSave)} ); then in Load function: filename = openFileDialog.FileName; Stream myStream = openFileDialog.OpenFile(); ShapeTypeList = (ArrayList) s.Deserialize(myStream); ColorList = (ArrayList) s.Deserialize(myStream); CoordList = (ArrayList)s.Deserialize(myStream); SizeList = (ArrayList) s.Deserialize(myStream); arr=(ArrayList) s.Deserialize(myStream); arr=(ArrayList) s.Deserialize(myStream); for(int i=0;i

hi there, Thanks for the reply. Your solution works perfectly for binary serialization. However, i was wondering, does this concept works the same if i want to use XML serialization? Thanks.

The thing you are doing is going to work and is ok and Yes if you are using arrays you must know what data is where for preventing this you can use HashTable and use Enum or string names for keys these are wrote down here are just suggestions how about to create a GraphicsPathDataCollection Class and pass those GraphicsPaths to it and Serialize/ Deserialize the GraphicsPathDataCollection and take back your array of GraphicsPath after Deserializing. this needs some coding but is the correct way because you have a collection and maybe some other time you simply modify it for other use (like import and export...) there is an easier way too just like you did, but you can put all your GraphicsPathData inside a ArrayList not their serialized streams then Serialize the Array because as you know serializing is not such a fast job exeptionaly if you use SoapFormatter and in this way lots of resources going to be wasted. and one another thing if you are using .Net2.0 why we don't use List<> instead of ArrayList if all of our data are the same!. enum myPhases {gpData /*and other things you need to serialize */}; HashTable tableMustbeSerialized=new HashTable(); List gpList; //your Graphicspaths List gpdList=new List(); foreach(GraphicsPath gp in gpList) gpdList.Add(new GraphicsPathData(gp)); . . . //other things must be Serialized tableMustbeSerialized.Add(myPhases.gpData ,gpdList); . . . //add other Data too formatter.Serialize(myStream, tableMustbeSerialized); myStream.Close(); and of course after deserializing it can be easier retrieved object deserializedObject; HashTable myData=deserializedObject as HashTable; List gpdList=myData[myPhases.gpData] as List; if you need help I'm here :) good luck

I'm just curious who is hiding behind this name. I think he is also active with an other name and just wants to play the "bad boy"! All the best, Martin

What you need to do is, in your mouse down event, iterate over the objects again,... can you explain further? The problem is that for all the shape drawn before, i can't seem to save the area which they contained. if i mouseclick on the form, how can i check that the mouse click in within the area of the previously drawn shape. Please help, i've been cracking my head for hours. Thanks
