There are 2 new wxDB Functions :

wxColInf *wxDB::GetColumns(char *tableName, int *numCols, const char *userID)

This Function stores all (int numCols) information from the Table (char *tableName).
It returns the result in a wxColInf Stucture (Class)

int wxDB::GetKeyFields(char *tableName, wxColInf* colInf,int noCols)

Tries to find out if any (int noCols) of the columns (wxColInf* colInf)
in the Table (char *tableName) are  Primary or  Foreign Keys.
This Function is only called from GetColumns().

wxColFor

- This Class stores how this Column should be formated in a String :
- Output String (wxString s_Field),
- Formatted Objects (TIMESTAMP needs 7) (wxString s_Format[7]),
- Formatted Objects (wxString s_Menge[7]),
- Formatted Objects (TT MM YYYY HH MM SS m) (int i_Menge[7]),
- National (0=timestamp,1=EU,2=UK,3=International,4=US)int i_Nation),
- Datatype (from wxDB) (int I_dbDataType),
- Datatype (from SQL) (SWORD i_sqlDataType),
- int Format(int Nation, int dbDataType,SWORD sqlDataType,short columnSize,short decimalDigits);
- The Formatted Objects receive Standard Values and Format() is called.
- The Programmers can, if they want something special , change these Values and call Format() again -

This class is most definitely very much underdeveloped !
It was made so that the DBGrid could be realised.
Changes here are probable. (Suggestions welcomed)
