كود لجعل برنامجك في المقدمه
ضع الكود التالي في قسم التصريحات General



Private Declare Sub SetWindowPos Lib "user32" (ByVal hwnd As Long, ByVal hWndInsertAfter As Long, ByVal X As Long, ByVal Y As Long, ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long)


ثم ضع على حدث تحميل الفورم Form Load


Timer1.Interval = 1


ثم نضيف اداة التايمر

وعلى timer1 ونضيف في حدث التايمر هذا الكود

SetWindowPos Form1.hwnd, -1, 0, 0, 0, 0, 3

كود يقوم بحماية برنامجك حيث يعمل عدد من المرات (تحددها بنفسك)



Private Sub Form_Load()
retvalue = GetSetting("A", "0", "Runcount")
GD$ = Val(retvalue) + 1
SaveSetting "A", "0", "RunCount", GD$
If GD$ > 3 Then ' الرقم (3) يحدد عدد مرات التشغيل
MsgBox "انتهت مدة تشغيل البرنامج .. عليك بشراء النسخة الاصلية"
Unload FRM '
End If
End Sub




If GD$ > 3 Then ' الرقم (3) يحدد عدد مرات التشغيل

هنا رقم 3 نقوم بتغييره الى عدد المرات التي يقوم برنامجك بتشغيل فقط [ اي بعد ثلاث مرات من تشغيل برنامج بعدها تضهر رسال للمستخدم [ نتهت مدة تشغيل البرنامج .. عليك بشراء النسخة الاصلية ]

كود منع الزر الايمن بالماوس في برنامج
نضـع هذا الكود في الفورم في حدث .. MouseDown



Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
If Button = 2 Then
MsgBox "ممـنوع استخدام الزر الايمن بالماوس"
End If
End Sub

كود لمنع المستخدم من ادخال في مربع النص غير ارقام




Private Sub text1_keypress(keyascii As Integer)
If (keyascii < 48 Or keyascii > 57) Then keyascii = 0
End Sub


نضع هذا الكود في [ صندوق النص في الحدث keypress ]


كود لمعرفة عدد الاسطر في مربع النص [ صندوق النص ]
