Bind against a DataView instead of a DataSet or DataTable. You can easily create a DataView from a DataTable (just pass the DataTable to the DataView constructor) and then set DataView.AllowNew to false. Set the DataView as the DataGrid.DataSource.

I am doing an application in c# where i have 2 picture boxes.
In the first picture box i open a bitmap.
Then ,when i select a rectangle in this bitmap,the part of the image within the boundaries of the rectangle opens in the second picture box.
I cant actually open the part of the image (within the rectangle) as a separate image in the second picture box.
I used :
g=pictureBox2.CreateGraphics();
ImageAttributes remapAttributes;
ColorMap redToBlue;
redToBlue.oldColor = Color(255, 255, 0, 0);
redToBlue.newColor = Color(255, 0, 0, 255);
remapAttributes.SetRemapTable(1,&redToBlue);
g. DrawImage (globalImage,rect,zoomStart.X,zoomStart.Y,width,height,UnitPixel,remapAttributes,null,null);
but this code is giving many errors although its a copy from the one in the msdn.
please help

It seems as if you've copied the code from a C++ article, so this cannot work.
Graphics g=pictureBox2.CreateGraphics();
ImageAttributes remapAttributes = new ImageAttributes();
ColorMap redToBlue = new ColorMap();
redToBlue.OldColor = Color.FromArgb(255, 255, 0, 0);
redToBlue.NewColor = Color.FromArgb(255, 0, 0, 255);
remapAttributes.SetRemapTable(new ColorMap[] { redToBlue });
g.DrawImage(pictureBox1.Image,
pictureBox1.ClientRectangle,
0,
0,
pictureBox1.Width,
pictureBox1.Height,
GraphicsUnit.Pixel,
remapAttributes);
This is at least compilable if you have a pictureBox1 and pictureBox2 (and use using System.Drawing.Imaging; at the beginning of your code).

Hey,
has anybody tried using global hooks with WH_JOURNALRECORD or WH_JOURNALPLAYBACK in c#?
I used the class found at http://msdn.microsoft.com/msdnmag/issues/02/10/cuttingedge/ and it works fine with WH_MOUSE or WH_KEYBOARD (i have modified the code to make system-wide and it works fine).
However, once i set the hook to WH_JOURNALRECORD or WH_JOURNALPLAYBACK the system stops responding (but the mouse still works) and the system only un-freezes when i pres CTRL+ALT+DEL...i also noticed that the journal callback procedure is never called in WH_JOURNALRECORD but it IS called after WH_JOURNALPLAYBACK but ONLY when i press CTRL+ALT+DEL...anybody knows anything about this?
Thanks

try this:
your web page(test.htm):
<html>
<head>
<title>WebForm1</title>
<script>
function ShowHelp()
{
var height = window.screen.height;
var width = window.screen.width;
var aWidth = width * 3 / 4;
var bWidth = width / 4;
window.moveTo(0,0);
window.resizeTo(aWidth,height);
window.open("Help.htm","Help","top=0,left=" + aWidth + ",height=" + height + ",width=" + bWidth + ",status=no,toolbar=no,menubar=no,location=no,scrollbars=no,resizable=no");
}
</script>
</head>
<body>
<a href="javascript:ShowHelp();">Help</a>
</body>
</html>
your help page(help.htm):
<HTML>
<HEAD>
<title>Help</title>
<script>
function CloseHelp()
{
var height = window.screen.height;
var width = window.screen.width;
window.opener.moveTo(0,0);
window.opener.resizeTo(width,height);
}
</script>
</HEAD>
<body onunload="javascript:CloseHelp();">
</body>
</HTML>

Hi duaneye2003,
Your code is working fine... but(o oh) when we refresh the help.htm the body onunload function is getting fired which changes the opener page to its original(full screen) size but we don't want this.
So if possible can u tell me how to stop the onunload function while refreshing the help page.
I hope you are getting me.

Maybe this can solve this problem, but i don't think this is a good method.
change help.htm to this:
<HTML>
<head>
<title>Help</title>
<script>
function CloseHelp()
{
var height = window.screen.height;
var width = window.screen.width;
window.opener.moveTo(0,0);
window.opener.resizeTo(width,height);
}
function ResizeOpener()
{
var height = window.screen.height;
var width = window.screen.width;
var aWidth = width * 3 / 4;
var bWidth = width / 4;
window.opener.moveTo(0,0);
window.opener.resizeTo(aWidth,height);
}
</script>
</head>
<body onunload="javascript:CloseHelp();" onload="javascript:ResizeOpener();">
</body>
</HTML>
if you get a good idea, please tell me.

after click the help,help.htm is not loading.give me a solution.
|
|
|
|

I think u have to add ":" while calling the javascript function like this
body onunload="javascriptCloseHelp();">
change this to
body onunload="javascript:CloseHelp();">
Similarly change others also
Hope now it'll run.

I need to following filter in a dataview:
EventTime > '7:00' AND EventTime < '12:00'
But it simply doesn't work. The result is an empty grid showing up.
All properties have been linked correctly. So it should be something with this filter. Can anyone tell me how to use time as your RowFilter?

Hi,
How can i develop a application which can execute once and the executive file would be removed from device. Like: After program show a message, this executive file is removed. I got a straight way that after the application executes, deleting this application file. But how? Running program couldn't delete itself. Any suggestion is welcome. Thanks!
Regards, ginee

Hi!
I don't think that it is possible to delete a program that's running, but you could add an entry to HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce to delete the file at the next system start.
Regards,
mav

You can't delete the .EXE file if it's running, or any of it's loaded .DLL's for that matter.
Your app would have to launch an external process, that handles changing out the executable you want to replace, then quit. This external process (.EXE) would have to wait for the original app to quit, then it could change out any of the files that it needs to upgrade or modify, then when done, launch the original app, then quit.

A simple solution would be to use a batch file (.bat) to run your application. You could run the executable from within the batch file and when you have exited the main application it could delete the executable. I use something like the following to quickly write a test sample, compile it, run it and then delete it when the app is done:
csc /target:winexe test.cs
pause
test.exe
del test.exe

In my "Drag Enter" method, how can I get the path of the file I dragged? Is it in the IDataObject somewhere or what?
/\ |_ E X E GG
|
|
|
|
|
AFAIK path and name are the dragged String data:
<br />
private void control_DragEnter(object sender, System.Windows.Forms.DragEventArgs e) {<br />
String droppedItem = (String)e.Data.GetData(typeof(String));<br />
}<br />

Dosn't seem to work.....

i want, form another form, and at a specified condition, to create an object from a certain control and add it to the first form, like :
namespace Win
{
public class Form1 : System.Windows.Forms.Form
{
private System.Windows.Forms.Button button1 = new Button();
private System.Windows.Forms.Button button2 = new Button();
public System.Windows.Forms.Panel panel1;
public Form1()
{
InitializeComponent();
}
static void Main()
{
Application.Run(new Form1());
}
private void button1_Click(object sender, System.EventArgs e)
{
this.Close();
}
private void button2_Click(object sender, System.EventArgs e)
{
Form2 f2 = new Form2();
f2.Show();
}
}
public class Form2 : System.Windows.Forms.Form
{
private System.Windows.Forms.Button button1 = new Button() ;
public Form2()
{
InitializeComponent();
}
private void button1_Click(object sender, System.EventArgs e)
{
Button b = new Button();
b.Text = "Hello" ;
Form1 f1 = new Form1();
f1.panel1.Controls.Add(b);
}
}
}
this code does not work. What is the wrong here ?
thanks

In Form2.button1_Click you're creating a new instance of Form1, adding a Button to its panel1 control and... well, that's it. f1 is going the way of the dodo bird when the method exits.
What I think you're trying to do is add the Button to the instance of Form1 that called Form2.Show in the first place. You'll need a reference to that object in Form2. You can pass it in Form2's constructor or as a property. Here's an example:
public class Form2 : Form
{
Form1 _form1;
public Form2(Form1 form1)
{
_form1 = form1;
}
private void button1_Click(object sender, EventArgs e)
{
_form1.panel1.Controls.Add(b);
}
}
public class Form1 : Form
{
private void button2_Click(object sender, System.EventArgs e)
{
Form2 f2 = new Form2(this);
f2.Show();
}
}
