Hello all,
In my html page I want to add an image say of 800x600. Now I want that
when ever I am given two coordinates on this image say (x1, y1)=(50,
100) and (x2, y2)=(200, 300), the java script code will trace these
coordinates on the image and draw the line between these two points.
Can anyone please help me in writing the javascript code of this
problem?
Thanks and Regards
Atif

I have a text field in a form. I want the user to be able to click
a DELETE button and have the character at the cursor position deleted.
This would be just as if the user had pressed the Back Space key on the
keyboard... But this is for a kiosk application with no keyboard :-(
so I need to program a delete button.
I have code that lets me insert text at the cursor position.
And I can move the ABSOLUTE cursor position from the start and...

I am new to C# and GDI+ so I may have missed a simple way of doing this.
I am trying to use the mouse to pick object up by seeing if the mouse position is Inside the object.
However, I am using the Transform method as follows

Matrix x = new Matrix();
x.Scale(shift,shift);
g.Transform=x;

I would like to set the caret position in a (single-line) textbox to a
position based on the number of pixels from the left of the control.
For example, I want the caret to be positioned 50 pixels from the left (or
as near to there as possible based on the characters in the control).
I basically have the position in which the user has positioned the mouse
cursor within the textbox, and want to react as if they had actually clicked
it....

Hi there,
I'm designing a winforms app in VB.NET 2.0 and have a textbox control and
also some toolbar buttons. I want to have it such that when the user clicks a
toolbar button, some predefined text - such as the date - is inserted into
the textbox at the point where the caret is. (It's assumed that the user will
be typing and then click the toolbar button.) From my research the textbox
control doesn't seem to support any method of...

Hello,
I've some geographical coordinates and I'd like to put them on a map.
Example: I've the map of the USA. Once I've selected Chicago, I'd like a
point-cross or what ever, on the Chicago point over the map.
How can this be done in PHP ?
I know you can do everything in GD, but does something similar already exist

QUESTION:
I have a web page containing a form that contains an image instead of a
submit button, e.g.
<form name='myform' action='get' method='otherpage.asp'>
<input type='image' src='picture.gif' name='myimage' id='myimage'>
</form>
When forms with image types are submitted, the value is not returned;
instead, when the form is submitted, the XY coordinates of the where
the user clicked on the image are sent. For example, if the user

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
