I love this..

Since Microsoft was only a budding monopoly then, Borland had OWL which was better than AFX at the time.

And if we had OWL for 32-bits, it would STILL be better than MFC/AFX Cool | :cool:

You can use the PlaySound[^] function from the multimedia SDK. Of course, you have first to record your welcome message yourself (or use an existing one).

Maybe off-topic, since I do not know what kind of application you are working on, but if you do something like that, do not forget to provide an option to deactivate it. Seems like a cool feature the first three times you use the software, but can become really annoying.

Insert the Microsoft Agent Activex control (agentctl.dll) into your project and then you can use code like:

CAgentCtlCharacters     m_AgentCharacters;
CAgentCtlCharacterEx    m_AgentCharacter;
...
m_AgentCharacters = m_agent.GetCharacters();
m_AgentCharacters.Load("Robby", _variant_t("robby.acs"));
m_AgentCharacter = m_AgentCharacters.Character("Robby");
m_AgentCharacter.Show(_variant_t());
//m_AgentCharacter.Play("Greet");
m_AgentCharacter.Speak(_variant_t("My name is Robby.  What is your name?"), _variant_t());

You will need to implement an ownerdrawn button, if you need to change the appearance such as the face colour. Try one of the many button controls[^] thats here at CodeProject.

I tried it just then and you are correct, it doesn't work. A more careful read of the documentation (as you often find yourself doing when stuff won't work) reveals the following:
"only owner-drawn buttons respond to the parent window processing this message".

Even I kept trying for sometime.

What puzzles me is that what purpose does it accomplish?

Following the "brute force and pig-ignorance" approach, I do the following to print an image (C code, but it should give the idea):

// get the printer height and width
iPageX = GetDeviceCaps (hdcPrn, HORZRES) ;
iPageY = GetDeviceCaps (hdcPrn, VERTRES) ;

// To make neater printouts, make a border of 10%
iTopMargin = iPageY / 10;
iLeftMargin = iPageX / 10;

// Leaving the area we potentially use as follows:
iPageX = iPageX - iLeftMargin - iLeftMargin;
iPageY = iPageY - iTopMargin - iTopMargin;

// ############################################
// Left out here - do some stuff to get my image and the page into the
// same aspect ratio
// ############################################

// Copy the DI bitmap to the printer
StretchDIBits(hdcPrn, iLeftMargin, iTopMargin, iPageX , iPageY,
	0, 0, iImageMaxX, iImageMaxY, lvpBits, lpBitMapHeader,
	DIB_RGB_COLORS, SRCCOPY);

I hope I haven't missed any relevant steps!

Handling Messages in Dialog

hi how should i handle keystrokes in a dialog???
i handle them with PreTranslateMessage() but it seems that it handles a single keystroke for example twice or more! so the code executes more than once. what should i do??

i do sth like this:

PreTanslateMessage(MSG*msg)
{
switch(msg->wpraram)
{
case VK_UP:
//do the code
}
}
but the code executes more than once

Stephen Hewitt25-Jan-06 22:01

In most cases handling them in PreTranslate message is unusual. If you want to however the code should look something like this:

<br />
PreTanslateMessage(MSG*msg)<br />
{<br />
    if ( msg->message == WM_CHAR )<br />
    {<br />
        switch(msg->wpraram)<br />
        {<br />
        case VK_UP:<br />
            //do the code<br />
        }<br />
    }<br />
}<br />

switch(msg->wpraram)
{

   return TRUE;
}
return FALSE;

Now it will process only once.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
