prucedure TvcGetCallerId(ch:integer;szBuf: PChar; want: Integer;stdcall;我这样传参数行吗？拜托大家教教我！procedure getNo;var aPchar : PChar; s : string; iLen : integer;begin s := '012345678901'; iLen := length(s); aPchar := Char(s); TvcGetCallerId(1, aPchar, iLen);end;

好像你没有加载dll吧prucedure TvcGetCallerId(ch:integer;szBuf: PChar; want: Integer;stdcall; external ‘ffd.dll’;aPchar := Char(s);//好像也有问题应该是 aPchar := PChar(S);
