关于路径的问题!请斑竹速回答~(100分)

ShellExecute(handle,ExtractFilePath(Application.Exename)+'/htcp.chm','-s','',SW_MAXIMIZE)   为什么出错?相对路径不可以用在这里吗?请斑竹速回答~

ShellExecute('Open', ExtractFilePath(Application.Exename)+'/htcp.chm','-s','', SW_MAXIMIZE)  

应该用ExtractFileDir，最后才不会有两个“//”出现。<br>ShellExecute('Open', ExtractFileDir(Application.Exename)+'/htcp.chm','-s','', SW_MAXIMIZE) &nbsp; <br>或者这样应该也可以：<br>ShellExecute('Open', ExtractFilePath(Application.Exename)+'htcp.chm','-s','', SW_MAXIMIZE) &nbsp; <br>

建议用showmessage显示一下得出的路径后面是否已经包含了'/'

关于ShellExecute函数：<br>&nbsp; &nbsp; 在ShellAPI单元中，ShellExecute函数的定义为：<br><br>function ShellExecute(hWnd: HWND; Operation, FileName, Parameters,<br>&nbsp; Directory: PChar; ShowCmd: Integer): HINST; stdcall;<br><br>作用：打开或打印一个指定的文件；<br>参数说明：<br>&nbsp; &nbsp; hWnd hwnd, &nbsp; &nbsp; &nbsp; &nbsp;//指向父窗口的句柄；<br>&nbsp; &nbsp; Operation: PChar, //指向一个null结尾的串以指明要执行的操作;<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 可以是"open"，"print"，"explore"，NULL;<br>&nbsp; &nbsp; FileName: PChar, &nbsp; &nbsp;//指向文件名或文件夹名串;<br>&nbsp; &nbsp; Parameters: PChar, //指向一个null结尾的串以指明可执行文件的参数;<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 如果FileName参数为文档，此参数应为NULL;<br>&nbsp; &nbsp; Directory: PChar, //指向一个null结尾的串以指明默认目录；<br>&nbsp; &nbsp; ShowCmd: Integer &nbsp; &nbsp;//文件在打开时是否显示；<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 如果FileName参数为文档，此参数应为0;<br><br>&nbsp; &nbsp; ExtractFilePath函数的返值已经包含了'/'，因此题目中ShellExecute函数<br>的正确写法应是：<br><br>ShellExecute(handle,'open',ExtractFilePath(Application.Exename)+'htcp.chm',<br>&nbsp; '-s','',SW_MAXIMIZE);<br>

多了'/'
