Hi,

i'm not sure if there's an easier way of doing this. but here's what i would do:

<br />
MemoryStream blah = new MemoryStream();<br />
dset.WriteXml(blah);<br />
string xmlStuff = System.Text.Encoding.Default.GetString(blah.GetBuffer());<br />

Hi,
Use the GetXML() method of dataset.

I'm doing this coding and its running properly. This coding is to create a chart that can be drag and drop. I create the Panel as the bar. The panel will be generated depend on input. But the problem is the Panel is generated too many as it like there is nonstop loop. Can anyone solve this problem...plz

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;

namespace CMSMS
{
public class mypanel:System.Windows.Forms.Panel
{
private bool isDragging=false;
public int x,y;

protected override void OnMouseDown(MouseEventArgs e)
{
base.OnMouseDown (e);

isDragging = true;
x = e.X;
y = e.Y;
}

protected override void OnMouseUp(MouseEventArgs e)
{
base.OnMouseUp (e);
isDragging = false;
}

protected override void OnMouseMove(MouseEventArgs e)
{
if (isDragging == true)
{
this.Left= e.X + this.Left - x;
this.Top = e.Y + this.Top - y;
}

}

}

}

using System;
using System.Drawing;
using System.Drawing.Imaging;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;

namespace CMSMS
{
///

/// Summary description for GranttChart.
///

public class GranttChart : System.Windows.Forms.Form
{

...
private mypanel [] bar = new mypanel[60];

...

public void GenerateGranttChart()
{

GenerateChart();

}

private void GenerateChart()
{

for (int i = 0; i < 10; i++)
{
int xPosition = 100;

for (index = 0; index < 10; index++)
{

for (int j = 0; j < 10; j++)

{
DrawPanel( xPosition, yPosition,j,brush, length);

xPosition += length;

}

yPosition -= range;
}
}
}

private void DrawPanel(int X,int Y,int j,SolidBrush brush, int l)
{
bar[j]=new mypanel();
this.bar[j].Size = new Size(l,20);
this.bar[j].BackColor = brush.Color;
this.bar[j].Location = new Point(X,Y);

}

rotected override void OnPaint(PaintEventArgs e)
{

...

GenerateChart();
...
}

First thing that I see is that you have 1000 iterations of DrawPanel. You have three nested loops, so you get the following logic:

for each iteration of the outermost loop 
  for each iteration of the next loop
    for each iteration of the inner loop
      DrawPanel
    end for
  end for
end for

BTW - you have declared an array with a fixed size of 60, so you will get an overflow. You would be much better off declaring this as List<mypanel> bar = new List<mypanel> and then using this instead.

Avoid splitter being focused?

Hello!

I've got a main dialog with two splitters. The problem is that after opening and closing a sub-dialog, one of the splitters gets the focus.

Before opening a sub-dialog: Screenshot[^]. After closing the dialog: Screenshot[^].

How can I avoid that the splitter gets the focus?

Best regards
Dominik

Hi
set the canFocus Property to false, the splitter shouldn't get the focus then

Hehe, tried that already Smile | :)

Unfortunately, the CanFocus property is read-only. You also cannot override it in a derived class Cry | :((

Another idea?

well what you could try in a derived class would be the setStyle method:

<br />
public class myFocusAvoidingSplitter:Splitter<br />
{<br />
    public myFocusAvoidingSplitter()<br />
    {<br />
        SetStyle(ControlStyles.Selectable,false);<br />
    }<br />
}<br />

hope that helps

How to extract data(characters) from image

Thanks for the tip! The splitter doesn't get the focus any more after the sub-dialog is closed.

One problem remains, though. When clicking the splitter with the left mouse, it appears like this: Screenshot[^].

But I guess this can be solved somehow by handling the mouse events. Thanks a lot again!

Hi ,
Please give me some guidance.How can we extract characters from image(which is in JPEG format) using image processing algorithms and how to remove noise from image. Could u please tell us how to proceed to reach our requirement.

Using OCR.

You can't do anything with the compressed file. You have to open the file so that you get the uncompressed data.

JanapatiBalu wrote:

That can be done using the same technique as programs like Raw image converters and Neat Image uses. I doubt that it will remove the kind of noise that you are trying to remove, though.

Build a program that noone in the world has managed to build so far.

I guess it would be much easier to build a clone of the system that you are trying to hack into, than it is to build the program that would hack into it.
