如何删除C ++中Word文档的写保护？

Question

I am copying a Word-document from a Server into my %localappdata%\\temp -Directory. But the Document is write-protected, and I can't modify or delete it. I don't want to manually remove the protection, it needs to get done automatically

My code to copy and remove the protection is

CopyFile(strTemplate, userTempDir, TRUE);
        SetFileAttributesA(userTempDir, FILE_ATTRIBUTE_NORMAL);

strTemplate is the PathToFile on the Server, userTempDir is the PathToFile to the copy directory (in this case "%localappdata%\\temp\\copy.doc")

But

SetFileAttributesA(userTempDir, FILE_ATTRIBUTE_NORMAL);

doesn't work. I'm pretty new to C++ so I don't know how to remove that Write-Protection

Answer 1

SetFileAttributes(userTempDir, GetFileAttributes(userTempDir) &~FILE_ATTRIBUTE_READONLY);

如果存在一个只读属性，它将删除该属性。
