从C打开Windows文件/文件夹属性对话框 [英] Open windows file/folder properties dialog from C
问题描述
我有这个小程序,目的是在指定的 info.lpFile
上显示Windows文件/文件夹属性对话框:
I have this tiny programm, which is intened to show windows file/folder properties dialog on the specified info.lpFile
:
#include <windows.h>
main() {
SHELLEXECUTEINFO info = {0};
info.cbSize = sizeof(SHELLEXECUTEINFO);
info.lpFile = "C:\\test.txt";
info.nShow = SW_SHOW;
info.fMask = 0x00000000;
info.lpVerb = "properties";
ShellExecuteEx(&info);
}
当我编译并执行它时,会收到以下错误消息:
When I compile and execute it, I get the following error message:
我正在使用Win7和Mingw gcc编译器。有人知道我的代码有什么问题吗?我错过了什么吗?
I'm using Win7 and Mingw gcc compiler. Does anybody knows what is wrong with my code? Am I missing something?
推荐答案
所示的所有代码中的第1个未正确初始化 info
。
1st of all the code as shown does not properly initialise info
.
要解决此更改
SHELLEXECUTEINFO info;
成为
SHELLEXECUTEINFO info = {0};
第二次使用 SEE_MASK_INVOKEIDLIST
表示 SHELLEXECUTEINFO
的成员 fMask
。

请注意,要看到打开的属性窗口,调用代码不得立即结束。因此,添加以下内容
Please note that to see the properties window open, the invoking code must not end immediately. So add something like
Sleep(10000);
到测试代码的末尾,如图所示。
to the end of your test code as shown.
对我有用的完整代码:
#include <windows.h>
int main(void)
{
SHELLEXECUTEINFO info = {0};
info.cbSize = sizeof info;
info.lpFile = L"C:\\tmp\\tmp.txt";
info.nShow = SW_SHOW;
info.fMask = SEE_MASK_INVOKEIDLIST;
info.lpVerb = L"properties";
ShellExecuteEx(&info);
Sleep(10000);
}
构建选项:
/ZI /nologo /W3 /WX- /Od /Oy- /D "WIN32" /D "_DEBUG" /D "_CONSOLE" /D "_UNICODE" /D "UNICODE" /Gm /EHsc /RTC1 /GS /fp:precise /Zc:wchar_t /Zc:forScope /Fp"Debug\SOxyzConsoleEmpty.pch" /Fa"Debug\" /Fo"Debug\" /Fd"Debug\vc100.pdb" /Gd /TC /analyze- /errorReport:queue
