MapXtreme2004 code reads the elements in the TAB table

For example, use notepad to open the TAB file "Ranan. Tab" to be accessed, you can see the following:

! Table! TABLE

Version 300

Charset WindowssimpCHinese

Definition Table

Type Native Charset "WindowsSimpCHINESE"

FIELDS 2

Geographical Code Char (10) Index 1;

Name Char (10);

Let's take a look at all "name" elements of the table. And add it to the DropDownList control.

Private static string _findlayername = "Ranan";

Private static string _findcolumnname = "name";

MapInfo.data.Table Table = mapinfo.Engine.Session.current.catalog.getTable (_FindlayerName);

IF (Table! = NULL)

{

MidataReader TR;

MicroNection Con = New MicroNection ();

MicMmand tc = con.createCommand ();

Tc.commandtext = "SELECT" _FindColumnName "from" _findlayername;

C.Open ();

Tr = tc.executeReader ();

While (Tr.Read ())

{

DropDownList1.Items.Add (tr.getstring (0));

}

Tc.cancel ();

Tc.dispose ();

Tr.Close ();

C. close ();

}
