foxpro programming

FoxPro 7, I slowly have the feeling that with visual FoxPro 7 I will never use Visual FoxPro 6, which is also my judgment on visual FoxPro 7, though it is imperfect, Some places are not satisfactory, I still think give it a 80 points should always be. Next I will talk about the use of feelings: Great development envi

of Visual FoxPro programming! Record-oriented and set-oriented contention According to the author's shallow cognition, the relational database processing can be divided into the oriented recording operation and the set-oriented operation. The client cursor system supported by various development tools is a record-oriented operation that supports absolute positioning between records, and more clearly, it

, not how to Chinese, the general Fox fans are not installed , so in terms of help, for friends who are unfamiliar with English, the English visual FoxPro 7 is the same as the Chinese visual FoxPro 6; Visual FoxPro 7 is not visual FoxPro 6 comparable in all respects, and the upgrade development tool is inevitable. So,

has indeed spent a lot of effort! IntelliSense. I used to envy Visual Basic programmers, who had the IntelliSense tools in Visual Basic 5 o'clock, so they didn't have to memorize a lot of commands, functions, external ActiveX, COM programming can easily get the object's methods, attributes, Event. In Visual FoxPro, if there is no difficulty in remembering the things of Visual

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

my experience, the MDB database for access applies to 200,000 data/table applications (its only advantage over the Visual FoxPro database is that all of the database components are in the same MDB file, and Fox's database may be composed of multiple files, which is messy). And the amount of data added, it's not that access can't handle it, it's inefficient--queries, indexes are slow. Visual FoxPro can hand

, looks so pale, really "sea change Kuwata" Ah! With only this enhancement, visual FoxPro 8 is already dazzling, believing that no developer will be tempted to "structured exception handling" to upgrade to Visual FoxPro 8! (ii) CursorAdapter class The CursorAdapter class provided by Visual FoxPro 8 is also a popular delight. CursorAdapter is an object-oriented

(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 mo

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 processing, COM

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

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 support for XML Web service is based on MS XML and SOAP components, and the core of writi

visual| Data | questions Topics: Multiple users and data buffering issues in Visual FoxPro Shaoxing Many Fox friends (foxers) are from DBASE―FOXBASE―FOXPRO―VFP such a road come over, if say from FoxBase to Foxpro is a leap, then from the Foxpro to VFP is a sublimation. The two major changes in the long

Objective Many friends may have the understanding that Visual FoxPro has limited support for Graph objects-it's hard to use it to make rich, beautiful icons; there are some problems that seem insurmountable: print charts--visual FoxPro does not provide a way to print a form, graph Does not provide a way to print or Save as a picture ... I have this idea, but with the gradual establishment of "object-orien

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. The Vi

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

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

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

Say in front have been trying to write something about visual FoxPro 7, but not the pen. There are two reasons: one is busy, lazy to write, and then visual FoxPro 7 new features do not float on the surface, a very difficult to understand, not to mention written article. Difficult, or to write. I am not a professional Visual FoxPro programmer, I am a fan, so I d

The definition of Web service in this article is part of the "C # asp.net" Book of Taiwan's Peak Information Co., Ltd. Visual FoxPro 7 full support for Web Service Visual FoxPro 7 has special support for Web service, a major selling point of visual FoxPro 7

Where does the data sequence occur? Data series is based on a very critical issue, which refers to a set of related data points that are plotted in a chart. Each data series in a chart has a specific color or pattern and is described in the legend of the chart. (You can draw one or more data series in a chart, but there can be only one data series in a pie chart.) ） In terms of the previous example data source table, we can specify "quarter" as the basis for the data sequence ("quarter" as the
