Create a Bitmap, create a Graphics object from the bitmap and use methods on the Graphics class to draw on it

There is no background color property in a bmp image.

You can load the file into a Bitmap object and use the GetPixel method to get the color of specific pixels. You have to choose a method to determine some color that can be used as background color. I would suggest that you examine the corner pixels of the image.

GetPixel should do it, if you assume that a particulal pixel ( such as 0,0 ) is always the background color. Otherwise, it can't be done, not without a ton of work. How do you define the background color ? How do you detect which color is the 'background' ?

You could find the color that is predominant in the picture and assume that it's the background color. Most of the time you'll be right. Also, as a second test, checking the corner pixels and other regions near the edges for that color would be a good idea.

Sometimes, the predominant color may be that of human skin, so you could have an range of skin color, and rule out a possible background color if it falls in between that range.

hi
I'm trying to do this:
for (i=0;i<100;i++)
{
Point p = new Point(i,100);
this.Location = p ;
}

but the form is not responding ,
I put this code after calling initialized component method.
in the constructor of the form

what is the problem?

It's happening so fast that you cant see it, try to break every loop using
System.Threading.Thread.Sleep(20);

Checking checked list box

27-May-07 22:14

Try adding Application.DoEvents() to force the page to redraw itself.

I'm also not sure if the Location property is the right one, try setting the Top and Left properties instead.

Hi,
How do you check/uncheck all the items in a check box list control?

Loop through the items in the Checkbox list

<br />
  ListItemCollection list= CheckBoxList1.Items;<br />
        foreach (ListItem item in list)<br />
        {<br />
            item.Selected = true;<br />
        <br />
        }<br />

But when you want to make all items to be selected ?

Thanks and Regards

First Register that control in your aspx page
<%@ Register tagprefix="tagprefix"
namespace="namespace"
assembly="assembly" %>

Then use it in your aspx page
<code><tagprefix:YourUserControl id="Give ID " runat="server" /></code>
IN Code behind (.cs) file use this id

Thanks and Regards
