Hi you can use AfxGetInstanceHandle() if u r using MFC or if it is Win32 HANDLE hModule in dllmain function is the HINSTANCE.

your Question : "Now another problem is how to get HINSTANCE in activex control?

Please help me out"

Answer:

To get the instance of an activex control you can use AfxGetInstanceHandle() in MFC.

eg: g_hInstance = AfxGetInstanceHandle();

or if u are developing a Win32 ActiveX Control you can use HANDLE hModule in dllmain function is the HINSTANCE.

like this way -

int Dllmain(HMODULE hModule...)
{
g_hInstance = (HINSTANCE) hModule;
......................
......................
}

i think now u got what i mean?

If you're using MFC, it'd be easily done with the CString::Mid() function:

CString str = _T("Name: Rajesh");
int iPos = str.Find(_T(":"),0);
AfxMessageBox(str.Mid(iPos+1));

Or, if you aren't using MFC, then perhaps this helps you:

TCHAR *tch = new TCHAR(20);
tch = _T("Name:Rajesh");

while(tch++)
{
    if(*tch == ':')
    {
        ::MessageBox(NULL, (tch+1), _T("Message"), MB_ICONINFORMATION);
        break;
    }
}delete tch;

If CString is used, write

CString str;
str.Mid (str.Find (':'));

If not using CString, write

char* pszName = strstr (variable, ":");
if (pszName != NULL)
{
  pszName is valid pointer.
}

Hi All,
"<Name>get input from user </Name>"
is it possible to get input from user as depicted in the above method.

The console will echo the "Name" tag and the cursor should be blinking in between the start and end of "Name" tag where in the user should enter a valid input.

kindly let me know. Thanks.

Regards,

lgatcodeproject

May be you could use gotoxy() to put the cursor in between.

Join microsoft's design team?

More usefully, for an application to get the Vista look, it need to include what's called a manifest.

Do a search for vista, application, manifest etc, and that should help.

Good luck,

Iain.

So should the OP be removing the manifest then (if he doesn't want the new look)?

My reading was that he had a "classic" application, which was just fine when the OK and other apps matched.

Now he has it on a "shiny" os, the "classic" look doesn't fit in.

And I'm pretty sure that vista requires a manifest for the app before it will apply the new user controls look to it. Beyond that, it gets beyond me. I *think* a manifest is just some xml in the resources or in a similarly named (eg. myapp.exe.manifest) file nearby. Which is why I pointed him at google with the search clues in order to preserve my illusion of omniscience.

WaitCommEvent() and new line

rp_suman12-Feb-08 21:00

I am debugging the application dealing with COM port.
The WaitCommEvent() function is called after setting mask with EV_RXCHAR and EV_TXEMPTY.
Even when there is no data coming from outside to COM port, WaitCommEvent() returns with new line character(10) continuously and the CPU usage becomes 100%.
Does anybody know why the new line character is coming?
Any help would be greatly appreciable!!

Best Regards,
