I have tested this in Windows XP, Windows 7 and Windows 2008R2. Make sure your account has privileges to install drivers.

On Windows XP the drivers are installed physically to:
C:\WINNT\system32\spool\drivers

And in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Environments

Nu är jag alltså certifierad java utvecklare enligt Sun. Nästa mål är att certifiera mig som Microsoft Certified Technology Specialist (MCTS) i .NET Framework 2.0.

LinkButton lb = ((LinkButton)dgItem.FindControl(”lb”));
lb.Attributes["onClick"] = ”return confirm(‘Do you really want to do that?’);”;

I dont really know why the onClick confirm-box does not fire before the href PostBack. However, the solution was to put the LinkButton inside a span and put the onClick attribute on the span.

// Web page
<span runat="server" id="spanLb">
<Linkbutton stuff/>
</span>

//Code-behind
HtmlControl spanLb = ((HtmlControl)dgItem.FindControl(”spanLb”));
spanLb.Attributes["onClick"] = ”return confirm(‘Do you really want to do that?’);”;

public static string StripTags(string str)
{
return Regex.Replace(str, @”<(.|\n)*?>”, string.Empty);
}

Instead of using firstChild and nextSibling you can use these functions (look below) that searches for the correct element in both major browsers.

Use getNextSibling(element) instead of element.nextSibling.
Use getFirstChild(element) instead of element.firstChild.

function getNextSibling(startBrother)
{
endBrother=startBrother.nextSibling;
while(endBrother.nodeType!=1)
{
endBrother = endBrother.nextSibling;
}
return endBrother;
}

function getFirstChild(elm)
{
if ( !elm.childNodes.length )
{
return;
}
var children = elm.childNodes.length;
for ( var i = 0; i <= children; ++i )
{
if ( elm.childNodes[i].nodeType == 1 )
{
return elm.childNodes[i];
}
}
return;
}

Exempel:

<input type=”text” style=”display:none”/>
