you also forgot to return a value from you operator+()
TOXCCT >>> GEII power

Generally I would implement:
class CTimeCode
{
CTimeCode& operator+=( const CTimeCode& rhs )
{
m_lTimeCode += rhs.m_lTimeCode;
return *this;
}
};
CTimeCode operator+( const CTimeCode& lhs, const CTimeCode& rhs )
{
CTimeCode ret( lhs );
ret += rhs;
return ret;
}Using a global- or namespace-scope operator+ allows conversions to happen on both operands (say, if you have a conversion operator or a single-operand constructor) whereas a class member only allows conversion on the right-hand operand.

i'm really tired of manual converting which make me doubt whether am i a man or a machine.

Hi,
I have SDI app that load files through CWinApp::OnFileOpen.
When the file dialog opens it is in the last opened directory. Normally this is the wrong directory.
When My program starts and File open is selected I want it to open in my default directory.
How can I set this without overriding OnFileOpen and using a CFileDialog 
Thanks

You could override CDocManager::DoPromptFileName, but bear in mind that CDocManager is an undocumented class and could change.
Note that Windows itself is providing this default behaviour, which users may have come to expect from their other applications. See the documentation for the OPENFILENAME structure's lpstrInitialDir member (MSDN Library[^]).

Yep thats what I have done,
and that works fine (as long as CDocManager doesnt change)
Thanks

Anybody been able to get CLSID_WebBrowser to work without having to use MFC and ATL but instead with CoCreateInstance? Mainly, the problem I see is that Navigate or Navigate2 seems to fail.
My code looks something like this:
//hr = CoCreateInstance(CLSID_InternetExplorer, NULL, CLSCTX_SERVER, IID_IWebBrowser2, (void**)&Browser);
hr = CoCreateInstance(CLSID_WebBrowser, NULL ,CLSCTX_INPROC, IID_IWebBrowser2, (void**)&Browser);
CLSID_InternetExplorer seems to work fine but the only problem is I cannot query IHTMLElementRender which is a problem because I want to do a SaveToDC. I can query IHTMLElement perfectly fine though. Here's some more code I have on that.
if (FAILED(hr) || (HtmlElement == NULL))
{
printf("Error: IHTMLDocument2::get_body failed\n");
return FALSE;
}
hr = HtmlElement->QueryInterface(IID_IHTMLElementRender, (void**)&HtmlRender);
if (FAILED(hr) || (HtmlRender == NULL))
{
printf("Error: Unable to QueryInterface for IID_IHTMLElementReader\n");
return FALSE;
}
Has anybody else had this problem? I've checked all over the web and have found little for using CoCreateInstance in conjunction with IHTMLElementRender.
Thanks,
Nathan

What's the return value of CoCreateInstance in this case?

Yes, the clipboard uses it, or at least it used to in earlier versions of Windows. A cursory glance at the documentation indicates it probably still does.
quzi wrote:
...or is some thing newer?
There are a variety of IPC mechanisms, such as COM, Mailslots, Pipes, and RPC, just to name a few.

Here is but one. Try Googling for others.

Use of DDE is discouraged on Windows Server 2003.
The DDE is a gaping security hole, as I understand it.
You are supposed to use the Micosoft Message Queue, or the other methods as David suggested.

Try this one: http://www.naughter.com/smtp.html
Very simple to use (nice C++ interface), and it even supports attachments, MIME, and some authentication protocols. Works very nicely for me.
Best regards,
Dominik
_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do?? 
(doesn't work on NT)

Check Dominik's post again. Did you notice the link he provided? It is a class for programmatically sending e-mail via SMTP. You can also find examples here.

Dominik and DavidCrow,
thanks. i downloaded a sample before which has the same name as your sample - an exe active control for VB - i don't know VB.
but this sample is totally wonderful, i think it is exactly what i need.
one Q:
when i run the program, it asks for configuration - host name/address, is it my PC's ip address?
thanks again.

Only if your PC is also the host.

Is there any way I can use a custom draw type technique when drawing an owner drawn tab control???
I only want to change the color of the text and allow the system to draw the rest...
Is this possible any hack or something I can use?
Thanks
How do I print my voice mail?

|

I have done the same thing with a customised button.
Try the following:-
Make a new class which is derived from CTabCtrl let it be
CCustomTabCtrl
let your tab be of type CCustomTabCtrl
then override DrawItem in the CCustomTabCtrl
in this DrawItem() call the default
CTabCtrl::DrawItem(lpDrawItemStruct);
just before writing your own code to color the text
I hope it will work
Even the word impossible says I am possible.
