hi guys.
i am trying to use pointers to functions in my dll to call a function in my .exe
i am storing my pointer in a global variable, so it can be called by any function.
the trouble is, i am finding that it can be only called by my addeventCallback function
i.e.
Code:
#include "dll.h"
EVENTCALLBACK evtcb = NULL;
BOOL WINAPI AddEventCallback(EVENTCALLBACK ptr) {
evtcb = ptr;
evtcb("pass on the message!");
evtcb("pass on the message!");
}
LRESULT CALLBACK GetMsgProc(int nCode, WPARAM wParam, LPARAM lParam) {
if(nCode < 0)
return CallNextHookEx(0, nCode, wParam, lParam);
evtcb("pass on the message!");
this displays "pass on the message" twicein the console, but when i try to cal evtcb() from GetMsgProc, it does not show again, meaning it has failed somewhere.
i know my GetMsgProc is fine as i have used other indicators such as MessageBepp(0) to show it is working.
what is the problem here?
cheers.

What do you mean by that ? You mean Microsoft Word ? If yes you have to look for 'Word automation'. Otherwise be more specific.

i want to retrieve the text from any text editors notepad, wordpad.
i want to retrive the text when the cursor is over the letter.

You'll need to use the EM_CHARFROMPOS message.

I have a pattern brush I would like to modify. The brush itself is to be used by windows internals.
My question is if it's at all possible to do something like
<br />
LOGBRUSH lb;<br />
::GetObject(hBrush, sizeof(LOGBRUSH), &lb);<br />
hbm = (HBITMAP) lb.lbHatch;<br />
::SelectObject(hdc, hbm);<br />
and the draw to the dc? If I already sent the hBrush to a win API function, will it be the very same I am trying to modify, or is windows using a copy of it (which means there's no point in doing the above)?
The win func is SetMenuInfo() but I doubt that matter.

To play mp3, I use MCIWndPlay macro. I want to make the tune to be played repeatedly until user wants a stop. Does anyone know how to do it?

(I am bing daft here - I have not much knowledge of mm programming.)
I wanted to use mci functions but hit a rock, because I do not know how to retrieve device id, and the device id is required to send the commands. Can you shed some light or point me to relevent sites? I tried but could not find any example telling me how to get the id, i.e. what name should I use in
MCIDEVICEID mciGetDeviceID(
LPCTSTR lpszDevice
);
I think once I know how to retrive the device Id I should be able to cook. PS I looked at the system.ini file, as a few internet findings suggest, but found nothing under the [mci] section.

Assuming you know the name of the .mp3 file (I'm boldly assuming it's a file), you can simply do:
<code>
char szMp3File [MAX_PATH];
strcpy (szMp3File, "C:\\myFile.mp3");
VERIFY (::sndPlaySound (szMp3File, SND_LOOP | SND_ASYNC));
...
<code>
VERIFY (::sndPlaySound (NULL, 0));

I tried the sndPlaySound(...) and passed in a .mp3 file but the mp3 file did not get played. instead, a wav file was played. I guess it is because this func works only for wav file so a default sound was played rather than the mp3 specifed.
In fact before I use the mp3, I was playing a wav file instead, using the PlaySound(...), which is similar to this one you suggested. I thought I should move up the ladder a bit by tackling more advanced multimedia stuff, which means the application can be more flexible. This is the background info of how I got here...
Do u happed to know how to get device id? It is really nice to know.

Perhaps this[^] article will help? Btw, I use BASS[^] to play MP3 files. I've also heard good things about FMOD[^]. Good luck!

I haven't much read about its architecture. But Generally interfaces should be exposed, as it is COM based architecture. Look for interface of your interest and use it. It should have api's like sendmessenge.

1. You better go for custom message box, the code you can get it by google search.
2. Or if you use windows NT based operating systems, you can try to use French localized dlls.

Declare a data member for your dialog:
NOTIFYICONDATA nid;
Then
<br />
ZeroMemory(&nid,sizeof(nid));<br />
nid.cbSize = sizeof(NOTIFYICONDATA);<br />
nid.hWnd = m_hWnd;<br />
nid.uID = 0;<br />
nid.uFlags = NIF_ICON | NIF_TIP;<br />
nid.uCallbackMessage = 0;<br />
nid.hIcon = LoadIcon(AfxGetInstanceHandle(),MAKEINTRESOURCE(IDI_....));<br />
lstrcpy(nid.szTip,"...some text ...");<br />
Shell_NotifyIcon(NIM_ADD,&nid);<br />
... and do not forget to remove the icon from tray when ready

If you do not get any response, you might consider sending an e-mail to Mark Russinovich or Bryce Cogswell.
