lpClassName is either an existing class name

e.g.
Button, Edit, SysTreeView32, ...

or a class that you registered via RegisterClassEx().

Use GetDesktopWindow() API to get Handle to Desktop Window, Then create a DC with this handle and enjoy Smile | :)

Imagine that you are creating a fabric of human destiny with the object of making men happy in the end, giving them peace and rest at last, but that it was essential and inevitable to torture to death only one tiny creature..and to found that edifice on its unavenged tears, would you consent to be the architect on those conditions?

Dear friends,

I try to develop a program which can hook into IE (toolbar buttons and/or menu items in IE window) to get all text in all text fields in a HTML page being displayed by IE. This will perform when user click on the toolbar button or menu item.

I don't know how to start and from where to begin. Could you please help me on this and thanks in advanced.

You will have to write a BHO(Browser Helper Object).
You can start from here[^]msdn

Also look for BHO samples here in codeproject also.

Thank you suhredayan very much for your kind help. I'm searching in codeproject for the sample code.

I will go back to this topic if there are some confusion to me and need your help again.

Once again, thank you.

Hi!

I’m creating an ActiveX control in my myapp.aspx-page using the <object> - tag.

<br />
<OBJECT id="objComp" style="Z-INDEX: 101; LEFT: 24px; WIDTH: 974px; POSITION: absolute; TOP: 40px; HEIGHT: 538px"<br />
</OBJECT><br />

At this time I’m only using the ActiveX technology to publish my MFC application on the net. I’m about to make a call to may webpage like this:

http://www.mypage.com/myapp.aspx?user=bill&password=12345

How may I pass the “user” and the “password” into my ActiveX?

Can I how do I access the properties of my ActiveX from my page?

The ActiveX is supposed to run on the client – not on the server.

hi ya its for sure that ActiveX runs on client side
you can access methods as well as properties exposed by your control from your page
e.g. if your control exposes a method like SetUseridPassword(BSTR usrID,BSR password) then you can access it as follows

<OBJECT
     ID="MyActiveXID"
     CLASSID="clsid:your-control-class-id-here"
     CODEBASE="TestAX.ocx"
     TYPE="application/x-oleobject"
>

then on any event (like button's onClick) call the following following function like onClick='InitValues'

don't forget to define this script in head section of your page.

<script language="JavaScript">

function InitValues()
{
MyActiveXID.SetUseridPassword("testusr","tstpassword")
}

</script>

Stopping a thread

Hi All,
I used SuspendThread and ExitInstance to stop a thread created using AfxBeginThread Function. But in some newsgroup messages it is stated that this is not the right method. I've used PostThreadMessage using WM_QUIT, but this is not working. So How to stop a thread created using AfxBeginThread function.
Thanx in Advance

To use PostThreadMessage it should be a UI Thread with message loop. Wot kind of thread you created worker thread or UI thread ?

Hi suhredayan,
Thanx for your reply.
It's a worker thread. TerminateThread is working but i am using critical
section for data handling, so MSDN states that it is a DANGEROUS function. Think that i must have to use waitforsingleobject().

The thread must finish execution on its own based on some condition. Use WaitForSingleObject or WaitForMultipleObjects if you got wait for some signal and u can also give time. There are other methods also that can be used to stop execution like signalling a flag etc.

Sujan Christo27-Sep-04 22:01

Hi Dubey,

You could create a shutdown event to stop the worker thread execution.
Here's an example how to do it:

//In your thread class:
//1. Declare m_eventShutdown variable of the type CEvent.
//2. Add function CYourThreadClass::ShutdownThread { m_eventShutdown.SetEvent();}
//
//In your thread function:
//
int CYourThreadClass::ThreadFunction()
{
while(1)
{
HANDLE h[2];
h[0] = m_eventShutdown.m_hObject;
h[1] = another handle;
DWORD dwRet = ::WaitForMultipleObjects(2,h,FALSE,YOURTIMEOUT)
if(dwRet==WAIT_OBJECT_0)
return 0; //exit thread
else if(dwRet==WAIT_OBJECT_1)
//handle your synchronization object
else if(dwRet==WAIT_TIMEOUT)
//handle timeout
else if(dwRet==WAIT_FAILED)
// handle error
}
}
//
//To terminate the worker thread call CYourThreadClass::ShutdownThread from your UI thread.
