Basic section The basic course of VFP Examples of complementary controls See example VFP: Use edit box control to do a "touch prize machine" Look at the example of VFP: A list box control to make a "Start menu" See Example VFP: Option button Group control Look at the example of

In VFP operation table record, can use the SQL statement, can also use the built-in append, replace, Delete/pack/zap, and other commands and with some record pointer positioning and data sorting commands and functions to use, and in vb/vb.net, use ADO /ado. NET and the properties and methods are available. VFP is as flexible as the C language, but perhaps it is because of this that many of those who have ju

In VFP, you can use SQL statements to manipulate tables, and you do not need to open the database when you use SQL statements to manipulate tables. This example describes the Select query statement (data retrieval), and the format of the SELECT statement refer to the Select SQL command or the SQL language tutorial. In the case of VFP: to locate and find the records in the table, we use the locate statement

In VFP, the system-defined class is called the base class, and the user cannot modify it, but the object can be created directly from the base class to implement the instantiation of the class, such as the class on the form Control toolbar that we commonly use is the system base class. VFP's base class is divided into Container class (Container) and control class (controls) two kinds. Simply put, a container class is a class that can contain other obj

This example in "Look at the case of VFP: To add records to the data table and verify that the input data is legitimate" on the basis of improvements, to achieve the addition of records can not only complete the verification of input data, but also has the function of automatically generating numbers. The code that automatically generates the number is added to the form's Init event and click in the Add button, which is invoked when the form is first

This example applies the knowledge of the GROUP BY clause in the SELECT statement, and for the SELECT statement, refer to the Select SQL command or the SQL language tutorial. This example applies to the Data environment and uses the "People Information table" in the "Data 1" database as the data source for the data environment, and the situation of the database is already looking at the case study VFP: sample database is given in the article, the runn

In the case of VFP: the output of the query results as a table or text file and several previous examples of the SELECT statement application, the combo box control Combo1 properties of the data aspect we set this: the RowSourceType property value is set to "N". The RowSource property value is set to department, gender, education, which means that the data source for the combo box control has been fixed at design time. But this kind of processing in s

This example to look at the case of VFP: more complex Query the article has made further improvements, in meeting the query function, but also the results of the query can be counted. This example also applies to the data environment, and using the "People Information table" in the data 1 database as the data source of the data environment, the situation of the database is already looking at the case of VFP

Looking at the case study VFP: Locating and locating the records in the table and looking at the case study VFP: Create a query with a SELECT statement in two examples, we can select a field to query from the combo box when querying. This example further improves the query by making it possible to select not only the fields to query from a combo box but also the operators (such as The production steps are

In this case, the text box on the form used to receive data is hidden, the Modify button is disabled, as shown in the following figure: Select the field you want to find in the combo box, click the Find button on the right after you enter the lookup in the text box, and then the Find button is disabled, and the Modify button and the text box to receive the data are activated. and displays the value of the current record (the record that satisfies the query criteria) in the text box, as shown

In this example, review the knowledge of the INNER JOIN clause in the SELECT statement, and for the SELECT statement, refer to the Select SQL command or the SQL language tutorial. The main operation of this example is done in the Init event of the form. Make a connection query in the event and output the query results as a temporary table (the table includes the name, gender, base salary, 3 fields of the Personnel information table, and the "bonus, living allowance, Endowment Insurance" 3 fields

We know that the normal VFP menu is displayed in the main screen (_screen), but if you want to use the top-level form to do the main interface of the software, _screen is to be blocked off. This creates a problem: _screen is gone, where should the software menu go? No, you can solve this problem with a menu that can only be called from the top-level form, and the call to this menu is in the Init event of the top-level form, not in the main program. T

Remote views and SPT (SQL pass through) are two built-in solutions for developing client/server programs, and if you use VFP more deeply, the contents of these two parts must be mastered.Because the content is more, the article divides into several articles several times to send out. But personally, the remote view and SPT is indivisible, although the SPT application is more, but if you do not have a more in-depth understanding of remote view, I think
