如何将INT64写入CString [英] How to write INT64 to CString

问题描述

我正在c ++窗口中进行编码.

I am coding in c++ windows.

INT64 dirID = -1;
CString querySQLStr = _T("");
querySQLStr.Format(L"select * from ImageInfo where FolderPath=%64d;", dirID);

querySQLStr always like this:
select * from ImageInfo where FolderPath=                                                            1214;

使用％64d是否正确? 非常感谢

is it right to use %64d？ Many Thanks

推荐答案

我没有方便使用Windows机器的Windows机器，但是我认为CString应该接受:

I don't have a windows machine handy to test this on, but I think CString should accept this:

querySQLStr.Format("%I64d", dirID);

可能值得注意的是，这是特定于Windows的，但是由于您使用的是CString，所以我认为这是可以的.

It's probably worth noting that this is windows specific, but since you're using CString I guess that's okay.
