How can I delete a file that is currently in use by another process in cpp win32?
问题
在卸载我的MSI应用程序时，调用DeleteFile()函数后，Program Data文件夹中的日志文件(.txt)没有被删除。通过使用GetErrorCode()函数，我可以检查它返回的错误代码32，这意味着文件正在使用中。有没有办法在卸载时删除这些日志文件？任何形式的理论或资源都将不胜感激。
我尝试使用下面的代码，但没有成功。即使是fclose()操作也没有产生任何积极的结果。
SHFILEOPSTRUCT file_op = {
NULL,
FO_DELETE,
dir,
"",
FOF_NOCONFIRMATION |
FOF_NOERRORUI |
FOF_SILENT,
false,
0,
"" };
SHFileOperation(&file_op);

While uninstalling my msi application , the log files(.txt) in Program Data folder are not getting deleted after calling DeleteFile() function. By using GetErrorCode() I could check its returning error code 32 which implies the file is in use.Is there a way I can delete these log files while uninstallation? Theory or source -Any kind of help would be appreciated.
I tried using the below code but it didn't work. Even fclose() operation didn't yield any positive results.
SHFILEOPSTRUCT file_op = {
NULL,
FO_DELETE,
dir,
"",
FOF_NOCONFIRMATION |
FOF_NOERRORUI |
FOF_SILENT,
false,
0,
"" };
SHFileOperation(&file_op);

你无法删除当前正在被另一个进程使用的文件。你可以尝试使用MoveFileEx函数，并设置MOVEFILE_DELAY_UNTIL_REBOOT标志。

You couldn't delete a file that is currently in use by another process. You could try to use Use MoveFileEx with the MOVEFILE_DELAY_UNTIL_REBOOT flag.
