我编一个Dll如下:
可我用API调用时出错,原因可能我用了DCOM,可能COM没有初始化?
应该如何初始化呢?library Project2;{ Important note about DLL memory management: ShareMem must be the
first unit in your library's USES clause AND your project's (select
Project-View Source) USES clause if your DLL exports any procedures or
functions that pass strings as parameters or function results. This
applies to all strings passed to and from your DLL--even those that
are nested in records and classes. ShareMem is the interface unit to
the BORLNDMM.DLL shared memory manager, which must be deployed along
with your DLL. To avoid using BORLNDMM.DLL, pass string information
using PChar or ShortString parameters. }uses

Classes,variants,windows,
Unit1 in 'Unit1.pas' {dm: TDataModule};{$R *.res}function SendSMS(telno:string;msg:string):integer;stdcall;
