I. Question proposalIn a recent project, I encountered an ASP operation problem on the FoxPro database table (*. DBF. In reality, many applications use the DBF table and how to use the data in the network environment makes many friends unable to do anything.I also checked a lot of information and did not find a detailed description of the solution. After testing, we have initially solved this problem and shared it with you.This article attempts to sol
In many Novell networks today, the data platform is still based on DOS FoxPro environment, general workstations are diskless stations, but the leadership of the workstation is often used to prepare a better, and equipped with WIN95 or WIN98 systems, if only for data query or simple processing,
will result in waste of resources, and if other work is done at the same time, it cannot ensure network security.
----In view of this, we have designed a

Part two: in. NET in the use of VFP written COM components
Fox can be flexible, intuitive, fast processing data, making it very suitable for application at the level of business logic. Starting with Visual FoxPro 5, Microsoft has been strengthening the development capabilities of the visual FoxPro COM components. Briefly summarize the features of visual FoxPro i
First, the question of the proposedThe most recent project encountered ASP pairs of FoxPro library tables (*. DBF) operation problem. In reality, many applications use DBF tables, how to use these data in the network environment, so many friends are helpless.I also checked a lot of information, did not find a detailed explanation for the solution. After the test, the preliminary solution to this problem, take out and share with you.This article attemp

Visual FoxPro makes it easy to organize data, define Database Rules, and create applications.Visual FoxPro integrated development environment not only has powerful object-oriented programming toolsAnd Client/Server capabilities, and supports Ole and ActiveX. If you have installed InternetExplorer, and it is the default browser. You can use the foll
---------- DBF import SQL Server table ----------
The following uses SQL2000, VFP6, and above as an example.
Method 1: execute the following statement in the query analyzer (select the corresponding database first)
-- If the SQL table that accepts the imported data already existsSelect * from openrowset ('msdasql ', 'driver = Microsoft Visual FoxPro Driver; SourceType = DBF; SourceDB = c :\', 'select * from aa. dbf ')
-- You can also import the corres
select "MicrosoftOle db provider for ODBC drivers, and then, "1. Select use data source name", select "DBASE" in the listFiles "; 2. "Enter Login Server Information" can be ignored; "3. enter the initial directory to be used. copy the directory path of the DBF file to the directory. The complete connection string is "provider = msdasql.1; persistSecurity info = false; Data Source = DBASE files; initial catalog = {data_path} "(where {data_path} is the. DBF storage path ). Click "test connection"
I went online for a long time and found the driver or something. I used to use Navicat directly.1. Create a database test in mysql.2. Open the plus sign on the left of the database test, which will display tables, views, functions, and so on.3. On the 'table' page, right-click the ---> Import wizard. For example, import foxpro --- here and select the dbase file (*. dbf) option.4. Select the dbf file. Select the encoding. Next step5. Whether to create
If we need to use the writeprivateprofilestring of the Win32 API functionFor this function, we first need to declare this function in the form that calls this function.If we want to execute it in the click function of a button, we should write it like this

In. Net, common VFP functions, no, finding an alternative, troublesome, and time-consuming. One of the learning practices.
With this Tookit, we can also use the same basic functions as VFP in. net. Thanks for your convenience !!
Tookit has been implemented beyond225VFP function.

Some time ago, I helped a student complete a Visual FoxPro Sorting Algorithm assignment question and recorded it here.
I. Question requirements:
The program requires the user to enter n numbers first, finally, the original input series are output in sequence, the series after the ascending order, the series after the ascending to the smallest arrangement, and the series after the large to small arrangement at both ends.

Data | database
The WWW web page of the Internet has a large number of two-dimensional tables, some of which are converted from a database. The author has written a program to automatically realize the database file into the Hypertext table, which is very efficient and is introduced to readers. The design idea of the program is simple: open. DBF database, which reads each field of the database in record order, and then adds the table control character of the HTML file to the. html file
In addition to directly configuring variables to modify the original content, is there a way to fine-tune the content of variables through simple actions? For example, you can delete, replace, and replace variable content! Yes! We can fine-tune the variable content through several simple small steps! Next, let's try it!
This section describes how to delete a variable.
The variable content can be easily dele
