Tree Creation

To create the tree view, the table's information schema view is queried and the results are parsed. The table name is created in the format of schema.tablename. This node is created as a single string and to create a shorter version of the table name later requires splitting the name at the decimal point.

Columns are created in the format of name, followed by a comma, and then the data type/length combination (such as "EventID,varchar(10)"). To get the column name requires splitting by the comma between the name/data type. That is useful for later.

Listing 9

foreach (DataRow tableRow in _information.Tables["Tables"].Rows)
      string tableSchema = tableRow["TABLE_SCHEMA"].ToString();
      string tableName = tableRow["TABLE_NAME"].ToString();
      TreeViewItem tableItem = new TreeViewItem();
      tableItem.Header = string.Format("{0}.{1}", tableSchema, tableName);
      DataView columnsView = _information.Tables["Columns"].DefaultView;
      columnsView.RowFilter = string.Format(
          "TABLE_NAME = '{1}' and TABLE_SCHEMA = '{0}'", tableSchema, tableName);
      for (int i = 0; i < columnsView.Count; i++)
            DataRow columnRow = columnsView[i].Row;
            string columnName = columnRow["COLUMN_NAME"].ToString();
            string dataType = columnRow["DATA_TYPE"].ToString();
            int precision = (int)(columnRow.IsNull("CHARACTER_MAXIMUM_LENGTH") 
              ? 0 
              : columnRow["CHARACTER_MAXIMUM_LENGTH"]);
            precision = !columnRow.IsNull("NUMERIC_PRECISION") 
               ? (int)columnRow["NUMERIC_PRECISION"]
              : precision;
            string text = columnName + ", " + dataType;
            if (precision > 0)
                  text += "(" + precision.ToString() + ")";
            TreeViewItem columnItem = new TreeViewItem();
            columnItem.Header = text;

All of the information gets pulled from the information schema views and creates the appropriate tree view items. To get the information back, it is collected from these tree view items and parsed appropriately.

Title: how to get list of tables from database using vb6.0 reply

The table_name is the field returned; in VB 6, you have to use ADO recordset to loop through the rows and get the table_name field, to get the list of the tables.

This presents a good start toward creating Stored Procs; however, I can see several limitations in it. Perhaps the most glaring limitation is the fact that it appears to only facilitate the creation of very basic SP's and, while that is useful, I am assisting C#/ASP.Net developers in the creation of much more complex SP's.

This is interesting and I can see a very good use for this type of programming in my current project. One reservation I have though is the use of the WPF. Specifically the Presentation part of WPF.
