$comcall calls a member of an open COM connection with the specified method and parameter, it is multithreaded and won't halt the script, an alias is called once the call returns.

If $comcall() fails when calling an object and $com() does not, this means that the object is not compatible with the threading model of mIRC, so $com() must be used. You can check the $comerr value in the alias to determine if a $comcall() failed or not.

Synopsis[edit]

$comcall(name,alias,member,method,type1,value1,...,typeN,valueN)

Parameters[edit]

• name - The name of the connection or the Nth connection
• alias - The name of an alias that will be called once the call returns
• member - The name of the function of the object
• method - A combination of the following value added together:

Value	Method
1	DISPATCH_METHOD - Call a member of an object
2	DISPATCH_PROPERTYGET - Return a value
3	(1+2) Call a member and return a value *
4	DISPATCH_PROPERTYPUT - Set a property
5	(1+4) Set a property with a member call *
6	(2+4) Set a property and return a value *
7	(1+2+4) Set a property and return a value with a member call *
8	DISPATCH_PROPERTYPUTREF - Set a property by reference
9	(1+8) Set a property by reference with a member call *
10	(2+8) Set a property by reference and return a value *

• type1 - The variable type, can be:

Type	Description	Values
i1	single byte signed integer	-128 to 127
ui1	single byte unsigned integer	0 to 255
i2	two byte signed integer	-32768 to 32767
ui2	two byte unsigned integer	0 to 65535
i4	four byte signed integer	+/- 2147483647
ui4	Holds unsigned 32-bit (4-byte) integers	0 through 4,294,967,295
int	integer	-2147483648 to 2147483647
uint	unsigned integer	0 to 4294967295
r4	real, 4-byte floating point number	1.17549435E-38 to 3.40282347E+38
r8	double real, 8-byte floating point number	2.2250738585072014E-308 - 1.7976931348623157E+308
cy	eight byte curreny number	-922337203685477.5625 to 922337203685477.5625
date	contains date and time, stored as an 8-byte floating-point number	+/-79,228,162,514,264,337,593,543,950,335
decimal	Holds signed 128-bit (16-byte) values representing 96-bit (12-byte) integer numbers.	+/-79,228,162,514,264,337,593,543,950,335
bool	contain any string or numeric representation.
bstr	null-terminated unicode character string value.	A string can contain from 0 to approximately 2 billion (2^31) Unicode characters.
variant	can contain string, date, time, boolean, or numeric values. When used, a data type must follow it: for example: variant int 5
dispatch	This data type indicates a pointer to an IDispatch interface on an OLE object (DBTYPE_IDISPATCH).
unknown	This data type indicates a pointer to an IUnknown interface on an OLE object (DBTYPE_IUNKNOWN).
error	This data type indicates a 32-bit error code (DBTYPE_ERROR)

You can pass a binary variable by prefixing the type of the variable with an '&' sign eg. $com(name,member,method,&bstr &binvar)

To make a variable by reference, postfix the data type with an asterisk and a variable name, for example: int* pIntOfBeer.

• value1 - the value assigned to the variable type

Properties[edit]

None

Example[edit]

alias runVbs {
  var %s = $mircdir $+ foo.vbs
  write -c foo.vbs  Dim c $lf c = 0 $lf Do While c < 10000000 $lf c = c + 1 $lf Loop
  .comopen x WScript.Shell
 
  ;mode 1 = comcall
  if ($1 == 1) noop $comcall(x, cbthread, Run, 1, bstr*, %s, int, 1, bool, 1)
  else {
    noop $com(x,  Run, 1, bstr*, %s, int, 1, bool, 1)
    .comclose x
  }
}
alias cbthread echo -a done | .comclose x

Compare //var %t $ticks | runvbs 1 | echo -a $calc($ticks - %t) vs //var %t $ticks | runvbs 2 | echo -a $calc($ticks - %t)
