hesitation: Exception handling! It is expected that it can have structured exception handling mechanism, limit the exception and its processing to the smallest range, so that the encapsulation of the code better. Visual FoxPro 8 has previously limited exception handling to global on Error routines and object error events, and they all have the problem that once

object-oriented programming and multi-layer development. The idea of the whole frame system is better object-oriented programming and better multi-layer development, so it has structured error handling, CursorAdapter and Statement Handle. Above, I used the term "derivation", from the meaning of the word must be the "connection handle" to explicitly generate a new statement Handle, but from the instance code you can see that the Con1 and Con2

Say in front 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 pro

rather than security management--this is a gentleman. 3._CRYPT.VCX Encryption Class This is MS for us to encapsulate the data encryption class, support string and file encryption, is the Windows API package, the code is very complex, I am not free to see, I will only use (this is the essence of RAD). For its use, you can see: Do FORM Home (2) + "\solution\ffc\crypto.scx" 4. Combining database events with _CRYPT.VCX encryption classes At this yea

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

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

Registering a Web Service in Intellsense Manger I mentioned that Visual FoxPro 7 has special support for Web service, which makes it clear that visual FoxPro 7 encapsulates Microsoft's SOAP components, which you can see in detail: _webservices.vcx (Home () + "FFC \_webservices.vcx ").

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. Visual FoxPro

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

Some time ago, I helped a student complete a Visual FoxPro Sorting Algorithm assignment question and recorded it here. I.
