Only buttons send BN_CLICKED (BN = button notification). You need to set the "notify" property for the static, and then handle the notification the control sends, STN_CLICKED.

OK this is what I did. I open class wiz and overrid the OnCommand() function. I then check to see if hte wParam is equal to my static control. If it does then call what ever function I want. It worked out extremly simple. Just make sure you set the noify in the static control settings.

You just need to make sure the control has a unique ID on the form and has the Notify style set for it in the resource editor.

17-Sep-02 14:55

I did a GetClientRect(&rect) in the OnInitialUpdate(), and got a set of values. In the OnSize event, I did the same and got a different value!! I did not resize!

OnSize() ran first, then OnInitialUpdate() when the app first started. I debugged and found that the values dont match! The OnSize rect is more accurate than the other, though (I believe)

Confused | :confused:

After I put the getClientRect of OnInitalupdate into an if, it worked predictably:

if(NULL != m_listdisplay.GetSafeHwnd())
{
        GetClientRect

}

Any idea why? Outside the if rect is different from that inside the if

try moving 'memDc.SelectObject(pOldBitmap)' before the clipboard calls.

i think selecting objects into a dc puts a lock on them until you deselect them; certainly, if you try to delete a bitmap selected into a dc it will not work, so this is worth a try.

It turned out to be declaring ClientDC instead of using GetDC()

C:\>tcpserver
We are awaiting a connection on port 5150.
accept failed with error 10014

here is the code where its failing...

<snippet>
// Accept a new connection when one arrives.

if ((NewConnection = accept(ListeningSocket, (SOCKADDR *) &ClientAddr,

{
printf("accept failed with error %d\n", WSAGetLastError());
closesocket(ListeningSocket);

This error code means "The system detected an invalid pointer address in attempting to use a pointer argument in a call.". Could post more code, particularly the declaration and initialization of the parameter you pass to accept()?

It is a lovely language, but it takes a very long time to say anything in it, because we do not say anything in it, unless it is worth taking a very long time to say, and to listen to.

And I would advise the use of the select() function if you don't want to block on accept().

TAPI voice recording problems

17-Sep-02 12:05

Hi,

I'm using TAPI 2.0 and the wave API to record voice conversations. This seems to work fine with the voice modems that I tried it with, but for some modems, the speaker is silent during the recording process. With other modems, the audio file contains garbage, no matter what audio format I use (I tried 8kHz mu-law and PCM). Is there a driver problem?

Thanks!

Printing on custom paper size

17-Sep-02 11:04

Dear Forum,

I have made a MFC application for a client that runs under all windows
os's.
Recently I have added functionality to print to a matrix or line printer
with a special paper size.
However the client must manually add a form (WinNT) or set a special
custom paper size (Win98/95) in which the paper size is defined.
Now I want to programmatically set the paper size.
Does anyone have an idea how to do this?

Greetings

Huub Sepers

Look at CView::OnPrint(...) and CPrintInfo::m_rectDraw. You may set the print area in OnBeginPrinting. You will have to set the print area in logical units.
Good luck!

Bold text in Owner Draw ComboBox

17-Sep-02 9:51

Hi All,

I've got an owner drawn combo box, and would like to draw the text in the box in bold, or normally, depending on the value of the DWORD in the item data. If 1, draw it bold, else draw normally.

So, how do I go about doing this? Get the selected font from the DC and modify it?

Thanks,

Aaron

I would create a new font, that contains the bold text, then select it in to the DC when you are ready to paint. And when you are done, replace the font with the old font. That is because you can never be certain where the DC may come from and you should restore it to its original state when you are finished using a DC.

1. get the font from the dc (or if thats null then grab a stock font like ANSI_VAR_FONT).

2. then get its logfont:

LOGFONT lf;

pFont->GetLogFont(&lf);

3. then modify the weight:

lf.lfWeight = FW_BOLD;

4. then create your own temp font and use it:

CFont font;

if (font.CreateFontIndirect(&lf))
{
:
:
}
