You'll have to handle the WM_KEYDOWN message in PreTranslateMessage member function.
<br />
BOOL CYourDlg::PreTranslateMessage(MSG* pMsg) <br />
{<br />
if(pMsg->message == WM_KEYDOWN)<br />
{<br />
...
}<br />
return CDialog::PreTranslateMessage(pMsg);<br />
}<br />
I hope it helps,

Hello All,
I have implemented a simple "hello world" WIN 32 Application which displays a tray icon when application is running and removes tray icon when application is closed.
My problem is when i kill the applcation process from task manager, the tray icon still remains in system tray. When I move the mouse cursor over the tray icon then the tray icon is removed.
Will it be possible to remove the tray icon when application is killed from task manager.
Any help is truly appreciated?
Thanks and Regards,
Madhu

you need to call something like this before exiting your app:
Shell_NotifyIcon(NIM_DELETE, &nidIconData);
|
|
|
|
|
ooops, sorry, i guess i am still sleepy, i missed that "when killed from task manager" part
|
|
|
|
|
One important thing: killing an application is a really bad thing to do  . When you kill an application, the clean-up code is not executed and that's why your icon still remains. The best solution to this problem: quit your application normally . Your application isn't supposed to be finished with the task manager killing it.
|
|
|
|
|
If you kill it by your task manager you can't predict what will happen and ensure that the icon is removed ...

Thanks for the reply.
My application is launched from installation. The applcation runs similiar to daemon or service. So, i need to terminate the process during uninstallation. I am using TerminateProcess() to kill the applcation.
Is there any alternative solution?
Thanks & Regards,
Madhu

You have 2 options after TerminateProcess() has killed it:
- Try Shell_NotifyIcon[^]with NIM_DELETE.
- Or force a repaint if you have the handle of the system tray:
<br />
CWnd *tray=FindWindow("Shell_TrayWnd", NULL);<br />
tray->SendMessage(WM_PAINT,0,0);<br />

Why are you using TerminateProcess to Kill the process(Even MSDN caution you tp use that in extreme case), why don't you WM_QUIT/WM_CLOSE or similiar function to close the application

Good Morning,
How can I convert ascii code to char in vc++ for ascii codes between 128 - 255.
|
|
|
|

converting int to char is implicit, it happens by itself.

a char in C/C++ is only an integer which contain the ascii code (1 byte so) of the character it stores.
so, writing the two following lines is equal :
char c = 57;
char c = 0x39;
char c = '9';

Since you mention codes 128 - 255, it is probably better to use unsigned char, since char will be negative in that range.
As other replies have said, char and ASCII codes are the same thing. You can see either a character or a numeric value when using printf (or whatever other output).
To see the difference, try the following:
<br />
char cMyChar;<br />
unsigned char ucMyUnsignChar;<br />
uMyChar = 77;
ucMyUnsignChar = 77;<br />
printf ("Character is %c, value is %i, unsigned is %c, unsign value is %i.\n",uMyChar,uMyChar,ucMyUnsignChar,ucMyUnsignChar);<br />
ucMyChar = 220;
ucMyUnsignChar = 220;<br />
printf ("Character is %c, value is %i, unsigned is %c, unsign value is %i.\n",uMyChar,uMyChar,ucMyUnsignChar,ucMyUnsignChar);<br />
NOTE: I'm not sure if this is correct - I don't have access to a C compiler on my office PC. I'm sure others will help!

What the other respondents are saying is correct, there realy is no conversion required.
I suspect that your probably having a character set (font) problem.

does anyone have a reliable way to detect whether a user's default input locale is RTL?
this is so that i can dynamically switch the direction of a richedit control.

Hello all,
how can I run a program? i want to run the Windows's calculator program which i don't know its location. (i only know that it is in program files).
also, how can run a non-executable program such as html files (Windows itself to run ie)? a function required.
|
|
|
|
|
Windows' calculator program location: %SystemRoot%\System32\calc.exe.
You can use 'spawn' to start new processes from your own program code.

ShellExecute does this for you, the HTML file as well.
