As you've discovered, CWairCursor won't work in a separate thread.
If you look at CWaitCursor, all it does is call SetCursor, and then restore your old one when its destructor is called.
If its in the same thread as the message pump (99.(% the main thread), then no messages are processed, including WM_MOUSEMOVE & WM_SETCURSOR.
If its in a separate thread, then the first time WM_SETCURSOR is processed, your cursor will be reset.
The solution is to override WM_SETCURSOR / OnSetCursor in your main program, or view (as appropriate).
BOOL CMyWndOrView::OnSetCursor (HITTYPE ht, CPoint pt)
{
if (ht == HTCLIENT && m_bMyThreadIsActive)
{
SetCursor (m_hMyThreadyCursor)
return TRUE;
}
else
return CWndParentClass:OnSetCursor (ht, pt);
}
This is off the top of my head - check the function prototype using MSDN, and you may also need to create the window class using a NULL cursor. See OnPreCreateWindow for MFC.
I hope this guides you in the right direction....

I'm currently using a dialog based application. May i know how do i open a file or link to the file by just selecting one of the items listed in the combo box?
For example, my program is to test IC. The combo box will contain different type of IC. Therefore, by choosing one of the items listed in the combo box, i will be able to send appropriate data to the hardware to do the testing process. So, is there anyone who may advice me on how to link the appropriate file corresponding to the chosen item in the combo box?
Thanks.

Hi,
Have you tried using the onclick event of the combo box? (I'm assuming you are using VS 2005).
Hope this might help you

Are you handling the CBN_SELCHANGE notification? If so, in that handler function, use the GetCurSel() and GetLBText() methods.

Use ClassWizard (Ctrl+W) to create a handler function for the CBN_SELCHANGE notification. In that handler function, call GetCurSel() and GetLBText(), like:
void MyDialog::OnSelChange()
{
int nIndex;
CString strText;
nIndex = m_combo.GetCurSel();
m_combo.GetLBText(nIndex, strText);
}

this doesn't mean anything. a combo box contains strings only, so when the Combo is populated, you have to store the source list, to recall the data selected later...

CBN_SELENDOK is the notification you want to be looking for. It is sent when the user selects and item, and confirms the selection. Do not respond to CBN_SELCHANGE because the user can select items and not confirm the selection (e.g. drop down the box, mouse over items to select them, and then press <esc> to cancel).
What you need to do after determining the user's action is another thing...

After declare CBN_SELCHANGE and get string of combobx you need to path of this string
|
|
|
|
|
We usually assign String value to an ID in the String table. e.g.
**************************************************
STRINGTABLE
BEGIN
IDS_ABOUTBOX "&About..."
IDS_VALUE "Value"
END
**************************************************
We use LoadString() method to retrive the value of IDS_VALUE.
However, how can we allocate a new value to IDS_VALUE in the code side? maybe "New Value"
thx!

Either change the .rc file and recompile, or use BeginUpdateResource() and UpdateResource().

Ok,
After googling my brains out, asking all my friends on ICR, Yahoo, AIM, and MSN/Live!, I stand corrected when i say "If you know how to use good keywords, you can find anything on google". I know in VB6, the MS-Winsock ActiveX control can become an array item simple by making
Winsock_Control.Index = 0
but i'm a Newb to networking in C++, and after reading a million articles, still have no clue how to make an array of sockets, or how to respond to incomming data from each one, without writing a seperat function for each one. i managed to get 1 to work after reading an article i found here on the site ( HUGE thanks to the author of "Programming TCP.doc" ) but, now i am left with the question, and a handful of hair...where are the arrays?? either a snippit of code, or a link to a good article would truely make my day

i opend the harddisk like this
sHardDisk.Format("\\\\.\\PhysicalDrive1");
HANDLE hDevice = CreateFile(sHardDisk,GENERIC_READ,......,0,OPEN_EXISTING,0,0);
then i read the Partition table using ReadFile
Everything is fine i can read all the partitions and extended partitions directly from harddisk but my questions is
How can i find out the logical drive name corresponding to the Partitions and extended
partitions that i read directly from hard disk?
Thank you in advance.

Hi,
Are you talking about something like this [^] ?

You got me curious now whats the difference between
"\\Device\\HarddiskVolume1" and "\\\\.\\PhysicalDrive1" i suspect one is a logical drive and the other is a device.
what i am doing is opening the harddisk reading directly from the sectors and loading the partition table and then reading the MFT.
I dislike feeling at home when i am abroad.
To all the virgins in the world thanks for Nothing.

hi all
i'm developping an application wich use a lot of xml documents...i want to parse a file xml, but i didn't find any function or Api to do it..
can you help me please...
thanks

You can use TinyXML[^] for this purpose. It's a nice cross-platform XML parser.
|
|
|
|
|
it's ok..thanks a lot
(merci beaucoup:->)

Depending on the features you want in a parser, there is Xerces/Xalan (which you can get off of www.apache.org), MSXML (which comes with Windows -- very similar API to Xerces), and TinyXML.

thanks Zac, i resolved my problem with Xerces, i'm now trying to find an application for converting from xml to C++ classes..if you know any tool for this, it will be a great day for me..
thanks again

use Serialization for this...

There are some tools that will generate these for you, but none of them are worth recommending. Personally, what I've always done when dealing with XML is to first write an .XSD file (schema), and then to write my class heirarchy by hand (which really shouldn't take you too long) and then to write a parsing routine to fill in the data as I march through it. When I've tried a few of the code generators, I've found myself fixing and changing much of the code anyway, so they really aren't all that useful.
