如何将CreateProcess转换为ShellExecuteEx？

我使用 MS detour 库来挂钩 CreateProcess，它在 Win7 上运行良好。然后我想用 ShellExecuteEx 替换迂回的 CreateProcess，以便我可以使用“runas”以管理员权限静默运行该程序。不幸的是，参数类型不一样。

这是函数签名：

CreateProcess( 
         LPCWSTR lpszImageName, 
         LPCWSTR lpszCmdLine, 
         LPSECURITY_ATTRIBUTES lpsaProcess, 
         LPSECURITY_ATTRIBUTES lpsaThread, 
         BOOL fInheritHandles, 
         DWORD fdwCreate, 
         LPVOID lpvEnvironment, 
         LPWSTR lpszCurDir, 
         LPSTARTUPINFOW lpsiStartInfo, 
         LPPROCESS_INFORMATION lppiProcInfo 
      );

这里我调用 ShellExecuteEx：

SHELLEXECUTEINFO ShExecInfo;
ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
ShExecInfo.fMask = 0 ;
ShExecInfo.hwnd = NULL;
ShExecInfo.lpVerb = NULL;
ShExecInfo.lpFile = lpszImageName; // this is obatined within deboured CreateProcess.
ShExecInfo.lpParameters = ""; 
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_SHOW;
ShExecInfo.hInstApp = NULL; 
ShellExecuteEx(&ShExecInfo);

但是，这个赋值有错误： ShExecInfo.lpFile = lpszImageName; VC2005 抱怨数据类型不一样：“无法从 const unsigned char * 转换为 const char *”。

但CreateProcess 中参数lpszImageName 的数据类型为LPCWSTR，ShExecInfo.lpFile 为LPCTSTR。

如果我使用 (const unsigned char*) 转换 lpszImageName，则 lpFile 的值只是 lpszImageName 值的第一个字母。

例如，如果 lpszImageName 是“C:\windows\system32\cmd.exe”。赋值后，lpFile 值仅为“C”。

如何从 LPCWSTR 转换为 LPCTSTR？或者我怎样才能进行转换？

谢谢！！！

原文

I use MS detour library to hook CreateProcess and it works fine on Win7. Then I want to replace the detoured CreateProcess with ShellExecuteEx so that I can use 'runas' to silently run the program with administrator priviledge. Unfortunately, the parameter type is not the same.

This is the function signature:

CreateProcess( 
         LPCWSTR lpszImageName, 
         LPCWSTR lpszCmdLine, 
         LPSECURITY_ATTRIBUTES lpsaProcess, 
         LPSECURITY_ATTRIBUTES lpsaThread, 
         BOOL fInheritHandles, 
         DWORD fdwCreate, 
         LPVOID lpvEnvironment, 
         LPWSTR lpszCurDir, 
         LPSTARTUPINFOW lpsiStartInfo, 
         LPPROCESS_INFORMATION lppiProcInfo 
      );

Here I call ShellExecuteEx:

SHELLEXECUTEINFO ShExecInfo;
ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
ShExecInfo.fMask = 0 ;
ShExecInfo.hwnd = NULL;
ShExecInfo.lpVerb = NULL;
ShExecInfo.lpFile = lpszImageName; // this is obatined within deboured CreateProcess.
ShExecInfo.lpParameters = ""; 
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_SHOW;
ShExecInfo.hInstApp = NULL; 
ShellExecuteEx(&ShExecInfo);

However, this assignment has error: ShExecInfo.lpFile = lpszImageName;
VC2005 complaints the data type is not the same: "cannot convert from const unsigned char * to const char *".

But the data type is LPCWSTR for parameter lpszImageName in CreateProcess and ShExecInfo.lpFile is LPCTSTR.

If I use (const unsigned char*) to convert lpszImageName, the value of lpFile is only the first letter of lpszImageName value.

For example, if lpszImageName is "C:\windows\system32\cmd.exe". After assignment, lpFile value is only 'C'.

How can I convert from LPCWSTR to LPCTSTR? Or How could I do the convertion?

Thanks!!!
