Hello,



I know this is off topic, but thought I would ask anyway.





I am writing my first C application which will be used to initiate a phone
call from my iseries application to a c++ pgm on the users pc. I want to
pass the phone number as a command argument, then pass that argument to the
dialer. My code is as follows:



int WINAPI WinMain( HINSTANCE hInst, HINSTANCE hPrevInst, LPSTR lpCmdLine,
int nCmdShow ) {



WCHAR szAddressToCall[] = L"201";

if ( S_OK == MakeCall(szAddressToCall) )





Right now, I have cardcoded 201 as the number to dial. I would like to pass
lpCmdLine. I have no idea how to cast a LPSTR to a WCHAR.

here is the win32 way to do it:

http://msdn2.microsoft.com/en-us/library/ms776413.aspx

wchar_t wideCmdLine[9999] ;
int nLx = ::strlen(lpCmdLine) ;
::MultiByteToWideChar( CP_ACP, MB_ERR_INVALID_CHARS, lpCmdLine, nLx,
wideCmdLine, 9999 ) ;

but you really want to look at using C#. get the free languages, sdk
and visual studio express from MSFT. use the wizard to create a
console application. then use p-invoke to call from c# into your phone
dialing dll function.
