You can do it with some javascript, BUT that will work only against totally non-tech users. Anyone who know how to disable javascript or view page source in browser will be able to steal whatever you send to client.

there you go:
document.oncontextmenu = function()
{
return false;
}
if ( document.layers )
{
window.captureEvents(Event.MOUSEDOWN);
window.onmousedown = function(e)
{
if ( e.target == document )
return false;
}
}
else
{
document.onmousedown = function()
{
return false;
}
}
// -->

how about ctrl+a to select all then ctrl+c to copy
or, view source and copy it all from there.
You will never ever stop someone dedicated to copying the text froma web browser, the best you will achieve is hindering the non-techy.

there must be a way of stopping some using ctrl c and a
how bout the below code i jus need to integrate it into asp.net
do you know how i could put on key down for asp.net?
function noCopyKey(e) {
var forbiddenKeys = new Array('c','x','v');
var keyCode = (e.keyCode) ? e.keyCode : e.which;
var isCtrl;
if(window.event)
isCtrl = e.ctrlKey
else
isCtrl = (window.Event) ? ((e.modifiers & Event.CTRL_MASK) == Event.CTRL_MASK) : false;
if(isCtrl) {
for(i = 0; i < forbiddenKeys.length; i++) {
if(forbiddenKeys[i] == String.fromCharCode(keyCode).toLowerCase()) {
alert('You are prompted to type this twice for a reason!');
return false;
}
}
}
return true;
}

Hello everybody,
I am developing an C#.NET application and i want to change the background color of message box that shown on button click....
Is there any way to change background color of MessageBox.....
|

No - you will have to create your own dialog (a window-form shown with .ShowDialog )

Hi,
I think that any customization on MessageBox beyond standard Image and Buttons options is not available.
Create your own messagebox by deriving from System.Windows.Form class
hope that helps

You'll have to create your own and open it with the ShowDialog() method. This is best approach since it will allow you more flexibility and control that with MessageBox.

I have a picturebox (imgViewer) which is displaying an image. Now i want to display another image (a smaller one) on top of this image. This is what i was doing:
private void btn_Path_Click(object sender, EventArgs e)
{
Bitmap path = new Bitmap(@"C:\Engg\Path.JPG");
Graphics graph = this.imgViewer.CreateGraphics();
graph.DrawImage(path, 0, 0);
graph.Dispose();
}
But nothing happens when i push my button (btn_Path). But when i change the code to draw on my form (instead of my picturebox), it works:
Graphics graph = this.CreateGraphics();
it properly paints on the form. What is wrong????? How can I paint on my picturebox which is already displaying an image?
|

change to:
<br />
private void btn_Path_Click(object sender, EventArgs e)<br />
{<br />
Bitmap path = new Bitmap(@"C:\Engg\Path.JPG");<br />
Graphics graph = Graphics.FromImage( this.imgViewer.Image );<br />
graph.DrawImage(path, 0, 0);<br />
<br />
graph.Dispose();<br />
}<br />
This should draw the "Path.JPG" on top of the stored image in the PictureViewer.

hey awsome dude.......... ur brilliant. it worked!!!!!
could u do me a favour and tell me what the difference was. I mean why was it working for the form and not for the picture box. they are both controls isnt it.
Thanks once again!!!!!

I guess the PictureBox get's an Invalidated message after you painted in it's client-area - so it just did what it should do after it's client-area got invalid - it painted it's internal image in it - and so undid your changes.
Even if your code worked - everytime the picturebox would repaint itself your changes would be gone.

Look for controls that exist on this site, or write your own.

You can search for an existing one or just create one yourself.

I create a user control that shows some different pictures(it look like just animation ). Here the code :
Bitmap dblbuffer;
g1=Graphics.FromImage(dblbuffer);
g1.Clear(this.BackColor);
g1.DrawImage(bmp1,...);//maybe next time it will draw anothe picture
g.DrawImageUnscaled(dblbuffer,0,0);
When backColor is not transparent,it works well.
But if backColor is transparent,the problem appear.That is,it cannot appropriately draw background when to draw smaller picture after bigger one.
So, how to copy the appropriate portion of the image(or background) of parent control onto my control's own surface.
thanks a lot

I mean that the code of "g1.Clear(this.BackColor)" dose not work well when BackColor is transparent.
