ทำ Form ที่เหลือหมดแล้วแต่มันติดแหงก อยู่ตรงนี้ที่เดียวเลย
คือหนูกำลังทำค่าที่ได้จากการหา Cheat Engine มาใส่ลงใน VB
แต่ที่หนูทำได้คือแค่เปลี่ยนค่าตรง Value ได้แต่แบบ 4 Byte
หนูอยากให้ตรง Value สามารถใส่ค่าจาก 4Byte เป็น Arry of byte ได้หรือเปล่าค่ะ
(ใส่ ReadWritingMemory.vb ไปในโปรเจ็คแล้วค่ะ )
Code (VB.NET)
Private Sub Button18_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button18.Click
WriteInteger("Project", &H957670, Value:=1063172178)
End Sub
Private Sub Button17_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button17.Click
WriteInteger("Project", &H957670, Value:=00 00 00 0F 00 00 00 1B 00 00 00 28 00 00 00 37 00 00 00 03 00 00 00 08 00 00 00 14)
End Sub
หนูลองทำโดยการเอาค่า Arry of byte มาใส่ Textbox แล้วกดปุ่ม Botton มันเกิดผลอะไรเลยค่ะ TT
