FUNGSI DALAM VISUAL FOXPRO Beberapa Fungsi yang diginakan dalam Microsoft Visual FoxPro adalah sebagai berikut: 1 Fungsi Tanggal Dan Waktu Visual FoxPro menyediakan sejunlah fungsi yang berkaitan dengan operasi tanggal dan waktu. Tabel berikut ini mencantumkan nama-nama fungsi yang berkaitan dengan hal ini beserta kegunaannya. Nama Fungsi, Keterangan dan Contoh sebagai berikut.
Options within this mode shall be only Cancel & Save. The Normal Mode shall enable the user to. Options within this mode shall be all else Next, Previous, Top,Bottom, Search, Print, Browse, Edit, Add, Delete, Exit, etc.2 For educational purposes, let us add two temporary buttons to our Restform. (See Below!).The valid event for the Edit Mode button should beDo SetEditMode. The valid event for the Normal Mode button should beDo SetNormalModeNormal Mode Should Allow No Option To Change The Record Fields - ScatterMemvar Memo1 It is customary to work with a copy of the data in the edit mode; thisgreatly facilitates the ease of canceling the process with no damage to theoriginal data. Some databases, such as FoxPro, have the option to easily createa set of local variables which contain a copy of the information in the currentrecord; this function is called Scatter in the x-base languages.In other database applications, such as Access, the programmer has to manuallycreate and assign the needed local variables.2 As you already know, Display Memory, will display all of the localvariables - followed by all of the system variables, etc.
In the screen capturebelow, you can see that local variable NewName was assigned the value Dr.ThomasE.Hicks; Display memory shows this immediately before all of the systemvariable. (See Below!)3 The current record is record 1 of 54.
The Customer record has 9 fields;the notes field is a memo field. Scatter Memvar Memo creates 9 new local variableswhose names are the same as those in the current record and whose values matchthose of the current record. Scatter Memvar makes a copy of all fieldsexcept memo fields.(See Below!)3 The database field Name takes precedence over the local memory variableName; therefore,? Name will display the contents of the field variable Name and?M.Name will display the contents of the local memory variable Name.In the screen capture below, both Name and M.Name contain Abstruse SteakHouse2 because of the scatter. Name = 'Joes' will change local memory variableM.Name to 'Joes'.
Replace Name With 'Mikes' will change the field Name of thecurrent record to 'Mikes'. See Below!Change Control Source Of All 10 Fields To Be Local Variable1 A good application must enable the user to enter the edit mode, make somechanges, and then discard those changes thus returning to the originalstate. Change the control source of each of the variables on the Rest form. Thismeans changing the control source of the Name1 field from Rest.Name to M.Name.Do likewise for all 9 fields; don't forget the Credit Card and Reservations!2 Program Main must Scatter Memvar Memo prior to launching the form!

Among theprocedures that you will have to alter will be Next, Previous, Top, & Bottom.The scatter should occur after the pointer is moved and before the form isrefreshed.3 Functions such as GoTo, Seek, and Skip are among the items that move therecord pointer. I leave it to you to decide exactly which functions need to bechanged.

Ifyou hit the Next and Previous buttons, you will find that the original recordhas not yet been changed; we will get to that in due time.Buttons Available In Edit Mode1 Once a user enters the Edit Mode, the record will soon be locked; otherswill not have access to this record.
