สวัสดีค่ะ ตอนนี้กำลังทำโปรแกรมบันทึกรายรับรายจ่ายจากCode::Blocks แล้วติดปัญหาที่แก้ไม่ได้สักทีเลยอยากขอความช่วยเหลือจากชาวพันทิปค่ะ TT
โดยในโปรแกรมจะมีการใช้เรื่องการบันทึกค่าดึงค่าจากไฟล์มาเกี่ยวข้อง ซึ่งเมื่อเวลาปิดโปรแกรมไปแล้วเปิดมาอีกครั้ง จะมีการโชว์ค่าสรุปการบันทึกครั้งล่าสุดก่อนปิดโปรแกรมให้
แต่ปัญหาตอนนี้คือ ถ้าบันทึก2เดือนติดกัน โดยไม่ปิดโปรแกรมระหว่างเดือนหรือวันสุดท้ายของเดือน เมื่อเปิดโปรแกรมมาอีกที วันที่ที่โชว์จะขึ้นแบบไม่ถูกต้อง
อันนี้คือรูปที่เปิดโปรแกรมมาอีกครั้งหลังจากบันทึกตั้งแต่วันที่ 1/1/2019 -2/1/2019 แล้วปิดโปรแกรม
อันนี้คือรูปที่เปิดโปรแกรมมาอีกครั้งหลังจากบันทึกตั้งแต่วันที่ 1/1/2019 -3/2/2019 แล้วปิดโปรแกรม
อันนี้คือโค้ดนะคะ
