Dear Lists,
For data entry I have developed a function in a Delphi DLL, which opens a
form, through which the user should enter attribute data for MapInfo
objects. It seemed not possible to access the MapInfo table from the DLL
while the table (DBF Format) is open in MapInfo. Does MapInfo open dbf-files
only for exclusive use ? How can I realise shared access to a MapInfo dBase
file, when it is opened in MI ? Is it necessary to use ODBC connections ?
In order to develop data entry forms visually, I am testing the possibilites
of using external Delphi DLLs. What approaches other than MapX have MapBasic
developers used to include external forms for data entry in their MapBasic
applications ?
I have chosen the approach of placing most of the attribute tables into a
second dbf table so that the table containing the map objects and the
attribute table are linked through a common field. The result is, however,
that some fields are not directly available for thematic shading anymore,
since I want to keep the second attribute table closed, so that it is
accessible from the external forms.
I hope I have been clear enough to specify the problems. MapX is not an
option, because the client wants to have a MapBasic application working from
within MapInfo.
TIA
