  9. Visual Report Writer and The Web (I)

    At the just ended Synergy 2013 conference held in Nashville, Tennessee we have shown how easy it will be to make Web Based Applications using the DataFlex Web Application Framework. One of the parts of a Web Application will be reporting. Data Access advises two reporting solutions; Dynamic AI and Visual Report Writer. During the Synergy sessions (symposium and trainings) demonstrations were given how relative easy it is to integrate the two reporting solutions in a Web Application made with the ...
  10. Report Data Sources

    This blog contains information on choosing and changing the data source in the Data Access report writer.

    Data Source?
    During the creation of a new report a data source needs to be selected. A data source makes it possible for the report writer to access the rows of data in tables. Currently 3 data source categories are available; DataFlex, ODBC and RDS.

    DataFlex
    For the DataFlex database the data source is either the list of tables (usually named filelist.cfg) ...

  11. How to Create a Checkbox in Your Report?

    Often a picture says more than a 1000 words... Well, a checkbox is not a picture but if well used it can draw the same kind of attention to the reader of the report results. Assume you want a checkbox on results of your Visual Report Writer report, how could you do this?

    First look at the following screenshot that shows what I mean with using a checkbox in your report output.

    If the phone ...

  12. A Line Around Your Report

    In this short blog I want to show you how you can make a line around the output of your Visual Report Writer report. Visual Report Writer does not have a box - or a line - object that can go over multiple sections. The development team has granted to need for such a feature and will implement this via a page layer. In general: objects should not go over sections.

    A Fake Box
    What is a box? A box is a rectangle consisting of two horizontal and two vertical lines. This means it is ...

  13. Saving Error Messages in Text Form

    Did you know that in Windows most error messages can be converted to text using the Copy (Ctrl+C) function? This is a tremendous, yet somewhat hidden and thus underutilized, feature of Windows.

    Most importantly, it works with standard Visual DataFlex errors and all messages based on the standard Windows MessageBox interface (see Message_Box, Info_Box, Stop_Box, etc. in the Visual DataFlex help index).

    So, for example, if you run the Order sample workspace and try to ...

  14. Recursive Use of Structs and Arrays

    In a recent post at the forums the question was given how to make use of a recursive struct. Years ago I wrote a training manual about Structs and Arrays and in one of the exercises the trainees had to write a routine that could read the files in a folder from a disk. A folder can have 0-N files and 0-N sub-folders. In this blog I will explain you how you can build the code to read the information using arrays and structs.

    Nested Structs
    Because a folder can have 0-N files and ...
  15. Fonts in Visual DataFlex

    There are many aspects to the discussions about how the new font system in Visual DataFlex works when compared to the old. This is actually a complex topic with a lot of different perspectives so this blog might be on the long side. I promise to do my best not to ramble (too much).

    Ill start by stating that the main goal in wirting this is to get everyone to a common understanding of the way fonts work: how the old system functioned, what we changed in moving to the new system and ...

  17. Use of Runtime Data Source with Visual Report Writer

    One of the new features of Visual Report Writer version 2.0 will be support of a Runtime Data Source (RDS). A runtime data source is a virtual table that is defined during report definition while the data is supplied via integration. This opens the way to report of data that does not come from a "real" database. In this blog you will read how to make a report based on the filelist.

    Report Definition
    Start Visual Report Writer and press Ctrl+N for a new report (or choose New Report ...
  18. Displaying Country Flags in a cDBCJGrid

    In september 2011 I published a blog about using other graphics in a cCJGrid class object.

With this short blog I will tell you how you can do this.

  19. How to Use SOAP Headers to Limit the Lifespan of a WebService Call

    In this blog I will show you how you can limit the amount of time that an application can call a webservice function. It is a small contribution to security and helps you against unwanted webservice calls.

    SOAP Headers
    A SOAP based WebService call always contains a body section and optionally can contain a header section. The use of a SOAP header section on both the Visual DataFlex server as well as client side is good documented in the help provided with the product. The good ...

    Do you use Windows 7 or Windows Vista? Are you having problems compiling your application in the Studio?

If you are seeing that problem then read on, I may have the solution (or at least a little good advice)...
