4: Design of the application
According to the module established above, it implements its specific function, and should provide the user to provide a selection interface, and there should be the operation function required by the user within each interface, which is the following form design and add code.
(1) form design
In this system, only three forms are mainly designed, namely: the main form, a senior administrator form, a normal operator form. Other specific operations are designed, so that the structure is clear and easy to add code, which avoids the compromise that handles the compromise of a large number of forms.
1, the main form: (mainform.scx)
Provide four controls for users, namely: ordinary operators, senior administrators, help, exit, and achieve different functions. This process and the process of calling a form. For example: do from advancedFomr.scx2, advanced administrator form: (AdvancedForm.scx)
This function form is some of the operations provided by senior administrators, such as bank registration, operator refresh, etc. This series of operations use paging box management to combine each function module. To implement the specific functions within the module, call to change the specific function properties in the paging box in this form. For example: some of the relevant code of the modified function in the second page (operator refresh) is as follows:
If thisform.pageframe1.page2. Modify .caption = 'Modify'
Poss = .f. && recognition is added or modified, modified to .f.
thisform.pageframe1.page2.n.value = Recno ()
* Change the text box to availability in order to modify
slightly
* Change the status of the button to avoid misuse
ThisForm.pageframe1.page2. Modify .caption = 'Save'
ThisForm.pageframe1.page2. Add .caption = 'restore'
ThisForm.pageframe1. refresh && form Refresh
Else && Executes Save Operation
TableUpdate (.t.) && form modification confirmation
* Change the text box unavailable state
slightly
* Recovery button
ThisForm.pageframe1.page2. Modify .caption = 'Modify'
ThisForm.pageframe1.page2. Add .caption = 'Add'
thisform.pageframe1.page2.text2.setfocus ()
* Recording pointer repositions
n = recno ()
Go N
Do Case
Case recno () = 1
THISFORM.PAGEFRAME1.PAGE2. Previous page .Nabled = .f.
ThisForm.pageframe1.page2. Next page .Enabled = .t.
Case recount () = Recount ()
THISFORM.PAGEFRAME1.PAGE2. Previous .enabled = .t.
ThisForm.pageframe1.page2. Next page .enabled = .f.
Otherwise
THISFORM.PAGEFRAME1.PAGE2. Previous .enabled = .t.
ThisForm.pageframe1.page2. Next page .Enabled = .t.
Endcase
MessageBox ('record saving success ", 0,' prompt information")
ENDIF
thisform.refresh
3, ordinary operator form: (CommonForm.scx)
The operation in this form is relatively more, and it is necessary to use a page box. The operation of the programming also considers the operation of different ordinary operators, so when the operator enters the specific deposit, withdrawal, etc., you should enter your operator code and password, and different operators should correspond to their own operations. . This is convenient for senior administrators to manage bankers and bank data.
