In reality, the security of the data is very important, especially in a very important department like the bank,
So the encryption of the data is particularly important, and in the long term, the pen is always the encryption and decryption of the various numbers.

. Interestingly, the various improvements in visual FoxPro in recent years have been more of a work in these areas, with the latest version of Visual FoxPro 7 adding a few features in this area, let me use four questions to illustrate the contribution of visual FoxPro in developing the middle tier:
Question one: Can Visual F
As mentioned several times before, Visual FoxPro 7 was officially released in mid-May 2001 and was listed in the United States in June. Now many netizens have been visual FoxPro 7 of the official version of English, after use, produced a variety of judgments. In the United States, it is believed that visual FoxPro 7 is the most "revolutionary" version of Fox's hi
quite obvious. Both access and assign are creative in controlling the data that is placed in your object. With the new Component Gallery (component library) and foundation Classes (base Class), you can easily move to the task of creating object-oriented applications. Better for COM support, we can create multithreaded COM components with Visual FoxPro after Server Pack 3.

Visual FoxPro 7 support for Web service is implemented through encapsulation of soap (simple Object Access Protocol), embodied in the FFC class library named WEBSERVICES.VCX. Visual FoxPro's support for Web service is divided into two parts: one is to let visual FoxPro act as
First part: Visual FoxPro OLE DB Provider
Speaking of Fox, the first impression is DBF data table, nearly 20 years of development process, do not know how many systems use DBF storage data. When you go to the. NET platform, how to access the Fox series of data is naturally a concern for many developers.
Prior to Visual FoxPro 7, Microsoft only provided Fox's ODBC driver. Using ODBC to access Fox data is i
Application of FoxPro in information management of the Three Gorges ProjectSource: Chinese thesis download center [07-07-20 17:08:00] Author: Li fangqing EDIT: studa20
Abstract: The Three Gorges Project is a world-class giant project with many professional categories, complicated technologies, and huge information management workload, the MIS system must be used to collect, sort, store, collect, analyze, and tabulation information. Over the past few y
Comparison of Visual FoxPro with other development tools
This is really a silly topic, the choice of development tools is entirely due to the tasks faced by programmers and personal preferences decided. As long as the tools you choose are qualified for the project you are engaged in, as long as you have sufficient knowledge of the development tools to cope with the changeable, complex work, as long as the tool continues to upgrade, you have no reason
Visual FoxPro is detached from Visual Studio
February 26, 2001, Microsoft announced the separation of visual FoxPro 7 from Visual Studio, is this good news or bad news? Let's analyze:
What have we lost?
Let's first observe that Visual FoxPro does not become a. NET language, and the technical loss is that you cannot develop a. NET based Web application.

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, ta

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
(iii) A new "connection"
Visual FoxPro 8 Enhancements in heterogeneous database programming, and more directly, improvements to SQL Server support. I think, at least in two aspects: one is through the CursorAdapter object to provide a more flexible than remote view, more easily programmable Cursor management object, another is based on the original concept of "connection", making "connection" processing more independent, "Connect" management more con

I remember the first time I contacted COM component programming, there is the question: there is no good way to pass the dataset. We know that Visual FoxPro is the most powerful data processing system, and its cursor strong, flexible support is unmatched. Since Visual FoxPro is so powerful at data set processing, COM programming, how to simply in various types of client programs and Visual
This article, which I wrote for Programmer magazine, was published in the 9th issue of the magazine in 2002, and it should be the first ever article on Visual FoxPro in the "programmer" magazine, thanks to Mr. Editor ...
Writing this article is very difficult, because the area involved is too new, there is little information to learn from, even the original. Fortunately, since last year I have been on and off a little bit about C #,. NET, and lately

Visual FoxPro 7 has special support for Web service, a major selling point of visual FoxPro 7
Part III: in. NET in the use of VFP written Web service
. NET and Java to be able to sell across different platforms, Java seems to pay attention to the cross-platform nature of the code itself. NET is more concerned with the cross-platform data, so. NET holds the banner of XML Web service in front of us, and in a sense. NET is an XML Web service.
