如何在Windows 7的Inno Setup安装程序中执行“ net use”命令?

[英]How to execute “net use” command from Inno Setup installer on Windows 7?

I'm working on an Inno Setup installer, which calls net use to connect to a shared server. 我正在使用Inno Setup安装程序,该安装程序会调用net use连接到共享服务器。 The installer can connect to the server, if it's running on Windows XP, but not on Windows 7. I think it's related to UAC as I type the same command, the server is connected on Windows 7, but the setup is running with admin privileges. 如果安装程序在Windows XP上运行,但不能在Windows 7上运行,则安装程序可以连接到该服务器。我认为它与UAC有关,因为我键入相同的命令,该服务器在Windows 7上已连接,但是安装程序以admin权限运行。

I'm using the following net use command through Exec or ShellExec script functions: 我正在通过ExecShellExec脚本函数使用以下net use命令:

/c net use \\servername password /user:username

Actually, here is a part of the script showing the net use command call: 实际上,这是脚本的一部分,显示了net use命令调用:

[Code] 
var 
  ErrorCode: Integer; 
  cmdString: String; 
  intvalue: Integer; 
  str: String; 

function InitializeSetup(): Boolean; 
begin 
  cmdString := '/c net use \\servername password /USER:username'; 
  ShellExec('', ExpandConstant('{cmd}'), cmdString , '', SW_SHOWNORMAL, 
    ewWaitUntilTerminated, ErrorCode) 
  if (ErrorCode = 0) then 
  begin 
    MsgBox(ExpandConstant('{cmd}'), mbInformation, MB_OK); 
  end; 
end;

Can anybody suggest how to use net use from Inno Setup on Windows 7? 有人可以建议在Windows 7的Inno Setup中使用net use吗? We just want to connect to a server and let user input name and password. 我们只想连接到服务器,然后让用户输入名称和密码。

Thank you! 谢谢!

How to connect to a remote resource invoking the credentials dialog? 如何连接到调用凭证对话框的远程资源?

Using a different view on your question, which is actually as the title of this answer says, I'd suggest you to use the WNetUseConnection function call with CONNECT_INTERACTIVE and CONNECT_PROMPT flags. 对问题使用不同的观点(实际上就是该答案的标题说),建议您将WNetUseConnection函数调用与CONNECT_INTERACTIVECONNECT_PROMPT标志一起使用。 That will in combination with empty user ID and password parameters invoke the credentials dialog (and that's what you wanted). 这将与空的用户ID和密码参数一起调用凭据对话框(这就是您想要的)。 In Inno Setup script it may look like this: 在Inno Setup脚本中,它可能如下所示:

[Setup]

AppVersion=1.5
