Isn't that what document.write does?

No, I dont think so. This page will say "Hello world!" not just "world!":
<html><br />
<body><br />
Hello <br />
<script type="text/javascript"><br />
document.write('world!');<br />
</script><br />
</body><br />
</html>
But if I inject similar code into control, it will just say "world!". This happens because script is deferred, but this is what I am trying to do, I need script to be able to execute but not to erase previous content.

Of course because the script is inline and run at that point when the browser is loading the page but that's not what you are doing because you are injecting the script after the page is finished loading. Your scenario is more like this script which will only display "world"
<head>
<title>Untitled Page</title>
<script type="text/javascript">
function loadPage()
{
document.write(" world");
}
</script>
</head>
<body onload="loadPage();">
hello
</body>
</html>

Right, now I get it, but how do I inject something that can write into the page without erasing it? Should I override some event like DocumentComplete? Can I make loaded page to get "busy" again and inject something then?

Well you already have the inject part working correct? So you need to figure out how to modify the HTML using javascript without using document.write. AFAIK you would use the HTML DOM[^] to do that. So for example say you had a page with span element in it and you wanted to change the text in the span to say "Code Project". You would get the reference to span element using the HTML DOM and then:
theSpan.innerText = "Code Project";
something like that for IE but all browsers are not equal. Of course how you get the reference to the span element depends on the page you are working with.

I want to use the .Net class "Math" functions in my vc++ SDI application like "Round" etc.
What header file and library I need to include for this?
Thanks,

If it's a normal C++ function, I think the answer is just plain "tough".
If you're using C++/CLI, then the other forum would be more appropriate.
There's nothing stopping you writing match code in C++ though - and lots of examples in the internet...

Hi All,
When there is a global HANDLE to an Event(unnamed) in a exe and another HANDLE in DLL to an Event(named) with the same name, will ResetEvent/SetEvent called in exe trigger the event wait in DLL?
Hope you understand the Q. Here is more explanation.
EXE --> declare HANDLE g_evt= CreateEvent()
DLL --> declare HANDLE g_evt = Createevent(name)
Exe(main thread) { <br />
SetEvent(g_evt); <br />
call to dll function x()...<br />
}<br />
<br />
<br />
<br />
DLL(main thread) x()<br />
{ <br />
ResetEvent(g_evt)<br />
waitforsingleobjectex(INFINITE, g_evt,TRUE);<br />
dosomething();<br />
}<br />
<br />
<br />
<br />
newthread()<br />
{<br />
log<br />
setevent(g_evt);<br />
}
when setevent is called in the exe, I see that the there is no wait
and dosomething() is called rightaway. Actually it should be waiting for the newthread() to execute and set the event. Since the call is commented it should be waiting for ever.
Setevent in exe is called for some other thread that is part of the exe. But it is signalling the dll wait object. Please kindly let me know if my reasoning is correct?
Thanks & Regards,
Dhana

I fell over at your first sentence.
You have two handles, one named, and one not named.
If you have two named handles, with the same name, then they would be the same underlying object. But you don't, so your two event handles will point to different things.
If you really want to talk to the same object, you will have to use the same name for both. And no-name != some name.

I am very very sorry.
Both the HANDLES have same names. One is defined in exe and one in a dll which the exe uses.
handle in the dll is pointing to a named event and other handle in exe is pointing to a unnamed event.
Hope now you can relate to my previous message.
Thank you.
Thanks & Regards,
Dhana

HANDLE 'names' are usually called identifiers.
However, as long as DLL symbol is not exported, they refers to different variables.

Unless you are talking about GetTickCount(), you'll need to explain what you mean by this.

When I needed to do this I used the Event Logging Functions API to read the system eventlog.
I created an eventlog class to wrap the Event Logging Functions.
You will need to look for the following events in the system eventlog from which you can determine the startup and shutdown times.
Start 6005
Shutdown 6006

You've only waited 26 minutes... That'd be good service if you were PAYING for the answer...
I presume you're talking about vista prettiness? If so, you need to include a manifest with your software - which is just a resource with certain parameters.
Try googling for MFC, 6, vista and manifest.

Are you wanting to be notified of such a change? If so, check out the WM_SETTINGCHANGE message.

Manifest can help.
