delphi中怎么调用函数过程
delphi中如何调用函数过程
------解决思路----------------------

不明觉厉,直接调用不就好了么,感觉好像是来搅乱的。。。
procedure TForm1.Button1Click(Sender: TObject);
begin
Button1.Caption :=function GetFileCount;
end;
改成
procedure TForm1.Button1Click(Sender: TObject);
begin
Button1.Caption :=inttostr(GetFileCount);
end;
------解决思路----------------------
错误:
function GetFileCount(srcPath, srcFileName: string): Integer;
定义在FormCreat事件 中,
Button事件是不能调用的。
修正:
你应该将它拉出来,放在
private
或
public
{ Public declarati
均可:
单元代码:
