VB ShellExecute 函数应用技巧

ShellExecute
声明:
Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" _ (ByVal hWnd As Long, ByVal lpOperation As String, _ 　ByVal lpFile As String, ByVal lpParameters As String, _ 　ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long
原型:
HINSTANCE ShellExecute(
　　HWND hwnd,　　　　　　　　　 //父窗口句柄
　　LPCTSTR lpOperation,　　　　 //操作,"open","print","explore"
　　LPCTSTR lpFile,　　　　　　　//文件名,前面可加路径
　　LPCTSTR lpParameters,　　　　//参数
　　LPCTSTR lpDirectory,　　　　 //默认文件夹
　　INT nShowCmd　　　　　　　　 //显示方式
);

打开一个应用程序
ShellExecute(this->m_hWnd,"open","calc.exe","","", SW_SHOW );
或
ShellExecute(this->m_hWnd,"open","notepad.exe","c:MyLog.log","",SW_SHOW );

打开一个同系统程序相关连的文档
ShellExecute(this->m_hWnd,"open","c:abc.txt","","",SW_SHOW );

激活相关程序，发送EMAIL
ShellExecute(this->m_hWnd,"open","mailto:[e-mail]","","", SW_SHOW );

打开文件夹

ShellExecute(handle, "open", path_to_folder, NULL, NULL, SW_SHOWNORMAL)

用系统打印机打印文档
ShellExecute(this->m_hWnd,"print","c:abc.txt","","", SW_HIDE);

本函数还可以用来连接到网页，照下面写就行了：
ShellExecute 0&, vbNullString, "", vbNullString, vbNullString, vbNormalFocus

　　或者这样写来发送Email：
ShellExecute me.hwnd, "open", "mailto:[e-mail]", vbNullString, vbNullString, SW_SHOW

另外有ShellExecute的替代用法，更加简单实用，不用API，一句Shell搞定！

连接到网页：
　　Shell "rundll32.exe url.dll,FileProtocolHandler "
打开文件：
　　Shell "rundll32.exe url.dll,FileProtocolHandler " & App.Path & "SHELLTST.TXT"
