Hi all ,
Please help me i m writing the code in VB6 Plz give me same code in C#.

Open "lpt1" For Output As #1<br />
   Print #1, Chr(27) & "@" 'Initialize printer<br />
   'Print #1, Chr(27) & "A" & Chr(15) ' set to 10/72"<br />

System.IO.StreamWriter writer = System.IO.File.CreateText("lpt1");
// Use Writer
writer.WriteLine("@");
writer.WriteLine("A" + ((char)15).ToString());
writer.WriteLine("M");

writer.Close();

Not sure about this, didn't test.

Next time write: "How to write to a file in c#", instead of "Give me a code", because people here usually do not like to "give a code" Smile | :)

Is there any way to insert objects to a section in the crystal report at runtime?
I can able to add a text object to a section(say section 3) during development time and associate a data table column to that text field. Is there any way to do this at runtime?

Thanks,
Nanda

if you r pass query(parameters) from the form to show the crystal report directly then i have a code for you that may help you.

i m using the same code also you must clear the reportsource(property of crystal repoet viewer) from the page design section.

Re: declaring xmlserializer where typeof is a class derived from arraylist

20-Aug-07 18:04

hi,

if i have a class like below:

[XmlRoot("MyData")]<br />
public class MyData:ArrayList<br />
{<br />
public MyData()<br />
{<br />
}<br />

public MyData(ArrayList shape, ArrayList color, ArrayList coord, ArrayList size, ArrayList gpd)<br />
{<br />
this.ShapeTypeList = shape;<br />
this.ColorList = color;<br />
this.CoordList = coord;<br />
this.SizeList = size;<br />
this.ArrS = gpd;<br />
}.......<br />
<br />

In the Form:

MyData data=new MyData();<br />
XmlSerializer s=new XmlSerializer(typeof(MyData));<br />

generates the error:

An unhandled exception of type 'System.InvalidOperationException' occurred in system.xml.dll<br />
<br />
Additional information: There was an error reflecting type 'DrawShape.MyData'.

How can i declare XmlSerializer for a Class MyData which inherits ArrayList class?

Thanks in advance

Re: declaring xmlserializer where typeof is a class derived from arraylist

20-Aug-07 23:03

Hi cyn8

At first I couldn't understand why you derived MyData from ArrayList !!

and the problem :

it is one of the boring and annoying one.I tested and my brain was going to blown (thank god for saving me) it seems it happens because xmlSerializer can just serialize public class,and it's public memebers no more no less

here is a few things must be paid attention for xml serializtion

1-your class must be public
2-your class must have parameterless constructor
3-all members are chosen must be public and if they are property type they must have both get and set
4-if your class would be embedded in another class Xml in serialization the embedded class must have XmlInclude Attribute or in the outer class type of inner class must be passed through
(another way is pass it's type throught XmlSerializer constructor in extraTypes argument but I'm not sure it works well)

hope the post would be useful

good luck Smile | :)

Re: declaring xmlserializer where typeof is a class derived from arraylist [modified]

20-Aug-07 23:11

and these are the codes I modified and tested (I'm really sorry about what I sent two days ago it didn't work well in desrialization Frown | :(

)

Here is Correct ones

 [XmlRoot("MyData")]
 [Serializable]
public class MyData
 {
     //it seems datas in each arraylist are the same type so if you're codinh in .NET2.0 or above use List<> instead of ArrayList

     ArrayList shapeTypeList;
     ArrayList colorList;
     ArrayList coordList;
     ArrayList sizeList;

     ArrayList graphicsPathDataList;

     [XmlArray("ShapeData")]
     [XmlArrayItem("Shape")]
     public ArrayList ShapeTypeList
     {
         get { return this.shapeTypeList; }
         set { this.shapeTypeList = value; }
     }

     [XmlArray("ColorData")]
     [XmlArrayItem("Color")]
     public ArrayList ColorList
     {
         get { return this.colorList; }
         set { this.colorList = value; }
     }

     [XmlArray("CoorinationData")]
     [XmlArrayItem("Coordination")]
     public ArrayList CoordList
     {
         get { return this.coordList; }
         set { this.coordList= value; }
     }

     [XmlArray("SizeData")]
     [XmlArrayItem("Size")]
     public ArrayList SizeList
     {
         get { return this.sizeList; }
         set { this.sizeList = value; }
     }

     [XmlArray("GPDDataCollection")]
     [XmlArrayItem("GPD",Type=typeof(GraphicsPathData))]
     public ArrayList GraphicsPathDataList
     {
         get { return this.graphicsPathDataList; }
         set { this.graphicsPathDataList = value; }
     }

     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.graphicsPathDataList = gpd;
     }

     private MyData()
     {
     }

     static MyData BinLoad(string path)
     {
         BinaryFormatter binSer=new BinaryFormatter();
         FileStream fo=new  FileStream(path,FileMode.Open);

         object data=binSer.Deserialize(fo);
         fo.Close();

         return data as MyData;
     }

     void BinSerialize(string path)
     {
         BinaryFormatter binSer=new BinaryFormatter();
         FileStream fo=new  FileStream(path,FileMode.OpenOrCreate);

         binSer.Serialize(fo,this);
         fo.Close();
     }

     static MyData XmlLoad(string path)
     {
         XmlSerializer xmlSer=new XmlSerializer(typeof(MyData));
         FileStream fo=new  FileStream(path,FileMode.Open);

         object data=xmlSer.Deserialize(fo);
         fo.Close();

         return data as MyData;
     }

     void XmlSerialize(string path)
     {
         XmlSerializer xmlSer=new XmlSerializer(this.GetType());
         FileStream fo=new  FileStream(path,FileMode.OpenOrCreate);

         xmlSer.Serialize(fo,this);
         fo.Close();
     }

     public enum SerializeTo{XML,Binary};

     public void Serialize(string path,SerializeTo to)
     {
         if(to==SerializeTo.Binary)
             this.BinSerialize(path);
         else
             this.XmlSerialize(path);
     }

     public static MyData Load(string path,SerializeTo to)
     {
         if(to==SerializeTo.Binary)
             return BinLoad(path);
         else
             return XmlLoad(path);
     }

 }

and the GraphicspathData must be modified somewhat like this

[Serializable]
[XmlRoot("GraphicsPathData")]
[XmlInclude(typeof(GraphicsPathData))]
public class GraphicsPathData
{
    byte[] types;
    PointF[] points;
    FillMode fillMode;


    [XmlArray("Types")]
    public byte[] Types
    {
        get { return this.types; }
        set { this.types = value; }
    }


    [XmlArray("Points")]
    public PointF[] Points
    {
        get { return this.points; }
        set { this.points = value; }
    }


    [XmlElement("FillMode")]
    public FillMode FillMode
    {
        get { return this.fillMode; }
        set { this.fillMode = value; }
    }

    public GraphicsPathData(GraphicsPath gp)
    {
        this.types = gp.PathTypes;
        this.points = gp.PathPoints;
        this.fillMode = gp.FillMode;
    }

    private GraphicsPathData()
    {
    }

    public static System.IO.Stream Serialize(GraphicsPathData gpd)
    {
        System.IO.MemoryStream ms = new System.IO.MemoryStream();

        System.Runtime.Serialization.Formatters.Binary.BinaryFormatter bf = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();

        bf.Serialize(ms, gpd);
        ms.Flush();
        return ms;
    }

    public static GraphicsPathData Deserialize(System.IO.Stream stream)
    {
        System.Runtime.Serialization.Formatters.Binary.BinaryFormatter bf = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();

        object obj = bf.Deserialize(stream);
        GraphicsPathData gpd = obj as GraphicsPathData;
        return gpd;
    }

    public static GraphicsPath GetGraphicsPath(GraphicsPathData gpd)
    {
        return new GraphicsPath(gpd.points, gpd.types, gpd.fillMode);
    }

    public static GraphicsPath GetGraphicsPath(System.IO.Stream gpdStream)
    {
        return GetGraphicsPath(Deserialize(gpdStream));
    }
}

good luck

hi, i'm sorry to say that i'm still stuck. The XML file can be generated but it is the same as shown before where there is no root and all the element is "ArrayOfAnyType"

Re: declaring xmlserializer where typeof is a class derived from arraylist

22-Aug-07 0:22

I Saw your code you didn't pay attention to rules I said before

IF YOU SERIALIZE AN ARRAYLIST DIRECTLY IT WOULD GIVE YOU THE RESULTS LIKE THAT!

MyData class actually is scheme for xmlSerializer so you don't need to put each array in serializer (in addition I said before retriving the data would be difficult too)

just put MyData Class in Serializer and all memebers you marked with attributes would be serialized

another thing is Color Struct properties are readonly so you can't seriailize it with xmlSerializer you must create a new Color Class with specific attributes

and Please don't serialize GraphicpathData and then serialize the streams again with xmlserializer i have doubt it works in Deserializing atall and ofcourse it waste the Resources

at last i put a complete code in

http://hjk.4shared.com

or direct link

THANK YOU!!! You are a LIFE SAVER!!!

Man, it is the people like you that makes this world a better place to live in:P

Your codes works like a charm.

However, there is a small problem, there seem to extra shape(exactly same shape) that is overlap on each shape. When i drag and drop on of the shape, the extra shape is temporary will be display at the original coordinate. But later if i want to drag the extra shape, it cannot be dragged and sometimes after i dragged a shape, all the extra shapes that is position on the saved shape original position will disappear. What you think that it is caused by?

Below are the codes in the Load function located in the form( ShapeTypeList,CoordList,SizeList are arraylist that contains the data for the shapes to be drawn on the form):

<br />
<br />
OpenFileDialog openFileDialog = new OpenFileDialog();<br />
			ArrayList arr =new ArrayList();<br />
			ArrayList ColorArr =new ArrayList();<br />
			if (openFileDialog.ShowDialog() == DialogResult.OK)<br />
			{<br />
				filename = openFileDialog.FileName;<br />
<br />
			ClearArrayList();<br />
				MyData deserializeData =MyData.Load(filename);<br />
				ShapeTypeList=deserializeData.ShapeTypeList;<br />
				CoordList=deserializeData.CoordList;<br />
				ColorArr=deserializeData.ColorList;<br />
				SizeList=deserializeData.SizeList;<br />
				arr=deserializeData.GraphicsPathData;<br />
<br />
				for(int j=0;j<ColorArr.Count;j++)<br />
				{<br />
					<br />
                    MyColor myC=(MyColor)ColorArr[j];<br />
					ColorList.Add(Color.FromArgb(myC.A,myC.R,myC.G,myC.B));<br />
<br />
				}<br />
<br />
				GraphicsPath myPath=new GraphicsPath();<br />
				int k=0;<br />
				for(int i=0;i<arr.Count;i++)<br />
				{<br />
					if((TypeOfShape)ShapeTypeList[i]==TypeOfShape.Oval||(TypeOfShape)ShapeTypeList[i]==TypeOfShape.Circle)<br />
					{<br />
						Point[] p=(Point[])CoordList[i];<br />
						Size s=(Size)SizeList[k];<br />
						myPath.AddEllipse(p[0].X,p[0].Y,s.Width,s.Height);<br />
						k++;<br />
					}<br />

Hi
at first thank you Smile | :)

.

and about the problem I don't know I get it or not but it seems you want to draw eeah sahpe in a single path right?

<code>GraphicsPath myPath=new GraphicsPath();</code>
int k=0;
for(int i=0;i {
if((TypeOfShape)ShapeTypeList[i]==TypeOfShape.Oval||(TypeOfShape)ShapeTypeList[i]==TypeOfShape.Circle)
{
Point[] p=(Point[])CoordList[i];
Size s=(Size)SizeList[k];
myPath.AddEllipse(p[0].X,p[0].Y,s.Width,s.Height);
k++;
}

else
{
myPath.AddPolygon((Point[])CoordList[i]);
}

<code>PathList.Add(myPath);</code>
}

//this.Refresh();
panel1.Invalidate();
}

in the code above I marked some lines as red if i was right about what you want to do

in the first red line you create an instance of the GraphicPath and darw all of the shapes inside it but in the second red line with ireratinf in the shapes you add it to a arrayList

so infact you draw all your shapes in just ine Graphic path and then for each shape add it to the arraylist so you have same Graphicpath as many as your shapes and you draw it

I think on your test so it wll make extra shape!

for solving this simply put the first red line in the loop and it would create ab instance of Graphicpath each time and prevent from extra shapes.

hope this helps

Best regards Smile | :)
