我想问一下大侠们：<br>这是我定义的一个函数，<br>function A(ServerName : PWideChar;<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;MsgName &nbsp; &nbsp;: PWideChar;<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;FromName &nbsp; : PWideChar;<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;Buf &nbsp; &nbsp; &nbsp; &nbsp;: PWideChar;<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;var BufLen : Integer) : Integer; cdecl; &nbsp; <br>可它编译时出现错误：<br>Unsatisfied forward or external declaration: 'A'

如果是自己写的函数,请在implementation部分写函数的实现.<br>如果是从Dll中连接,请<br>我想问一下大侠们：<br>这是我定义的一个函数，<br>function A(ServerName : PWideChar;<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;MsgName &nbsp; &nbsp;: PWideChar;<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;FromName &nbsp; : PWideChar;<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;Buf &nbsp; &nbsp; &nbsp; &nbsp;: PWideChar;<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;var BufLen : Integer) : Integer; cdecl; &nbsp; external 'dllname.dll';

LeeChange说得对，你的A函数没有写完整。请继续...

同意LeeChange的，如果自己写函数，不能放在Form类中，必须在implementation中实现<br>你的错误是因为将函数声明放在Form类中了

在implementation部分写函数体时用以下声明：<br>function [red]tform[/red].a(....);<br>begin<br>...<br>end;
