QDateTime to QString conversion

[Maaz Momin]

Just remove currentDateTime.

QDateTime buildtime = fileInfo.lastModified();
qDebug() << "buid month " << buildtime.toString("yyyy-MM-dd");
qDebug() << "it is a build path " << buildtime.toString("hh:ss:mm");

@Maaz-Momin

buid month ""
it is a build path ""

qdebug display this one sir not display the date and time

[Maaz Momin]

@Rameshguru Can you check fileInfo.exists() ?

@Rameshguru said in QDATETIME TO QString conversion:

("hh:ss:mm");

Also note you have seconds before minutes. Is this what you wanted?

[Rameshguru]

@Ratzz i want last compile time of build file

@Rameshguru
This works for me https://forum.qt.io/topic/98741/qdatetime-to-qstring-conversion/2.
Can you check fileInfo.exist() as @Maaz-Momin suggested?

[Rameshguru]

@Ratzz"
error
QFileinfo no member name exist

@Rameshguru said in QDATETIME TO QString conversion:

QFileinfo no member name exist

Can you show your code?

[Rameshguru]

@Ratzz
QFileInfo fileInfo;
fileInfo.setFile("D:\WorkingCode\build\Release\sample.exe");

	QDateTime buildtime = fileInfo.lastModified();
	
	qDebug() << "buid month " << buildtime.toString("yyyy-MM-dd");
	qDebug() << "it is a build path " << buildtime.toString("hh:mm:ss");

It's called exists() not exist()...

@Rameshguru This is you problem. Please verify your file path. Try adding one more '' in your path. e.g. D:\\WorkingCode...

@Rameshguru said in QDateTime to QString conversion:

  fileInfo.setFile("D:\WorkingCode\build\Release\sample.exe");

\ is an escape character in C++ strings. Your path is invalid.

In Qt, you should use / instead: "D:/WorkingCode/build/Release/sample.exe"
