Dear my friends.. I am still confused how to use the QDate and QDateEdit. 1. How can I issue the current date with QDate. 2. I want to add the currectDate with some days (addDays() ). 3. I want to detemine the output of the QDateEdit to become "yyyy-MM-dd". Here what I've done: ============= QDate tgl; QDate appdate = tgl->currentDate(); if ( appdateEdit->isEnabled() ){ appdate = appdateEdit->date(); } else{ if ( hari1radioButton->isChecked() ){ appdate = tgl->addDays(1); } if ( minggu1radioButton->isChecked() ){ appdate = tgl->addDays(7); } if ( hari14radioButton->isChecked() ){ appdate = tgl->addDays(14); } if ( minggu4radioButton->isChecked() ){ appdate = tgl->addDays(28); } } QTime apptime = apptimeEdit->time(); QString warned = "N"; QString sqlapprep = QString("insert into appointment (noapp, custid, salesid, date, time,done, warned) values('%1', '%1', '%1', '%1', '%1', 'N', 'N')") .arg(noapp) .arg(cid) .arg(sid) .arg( appdate.toString("yyyy-MM-dd") .arg( apptime.toString ); =============== And here is the error message as I compiled my code: In file included from .ui/funonseqform.cpp:38: funonseqform.ui.h: In member function `virtual void funonseqForm::sendreportSlot()': funonseqform.ui.h:279: error: base operand of `->' has non-pointer type `QDate' funonseqform.ui.h:287: error: base operand of `->' has non-pointer type `QDate' funonseqform.ui.h:290: error: base operand of `->' has non-pointer type `QDate' funonseqform.ui.h:293: error: base operand of `->' has non-pointer type `QDate' funonseqform.ui.h:296: error: base operand of `->' has non-pointer type `QDate' make: *** [.obj/funonseqform.o] Error 1 patrixlinux@patrix:~/arsip/proyek/qt/kv/client> ======== Please tell me where my mistake. Thank you very much in advance. __________________________________ Do you Yahoo!? Yahoo! Mail - 50x more storage than other providers! http://promotions.yahoo.com/new_mail
