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
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
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

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"
This simple method. I don't know. It's a pity.

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
