Populate powerpoint presentation with database values

Question

Somewhere in my application I need to create a powerpoint slides and populate it with DB values. I am able to create the slides using a local template. But I am not getting any idea how to populate it with DB values. I searched web and found this but it isn't helping me out. There is no chart or graph I want to populate. It is just simple text based on DB values.
Can someone help me here ?

This following code allows you to create a new slide, to select it and to add values to a table. You simply need now to read the DB and fill it in.

int newaddslidecounter = 0; // checking how many new slides have to be inserted in order to split the table
int startmultiplicator=1; // used in order to return current table row that must be pasted in new table
int amountrowsshown =7; // amount of shown rows per table
int fontsize = 12;
// set position of new table/chart
int topsize = 100;
int leftsize = 100;
int widthsize = 150;
int heightsize = 150;
Boolean alreadycreated = false; // checks if a table has already been created
//Resizing all tables
//and insert new Excel table instead while importing data from Excel table
//used for visualization of data
foreach (PowerPoint.Slide slide in presentation.Slides)
            {
                slide.Select();
                //loop through all shapes in slide
                foreach (PowerPoint.Shape pptshape in slide.Shapes)
                {
                    //Console.WriteLine("Shape type : " + pptshape.Type.ToString());
                    //check if current shape is a table
                    //in order to do the manipulation
                    if (pptshape.Type.ToString().Equals("msoTable"))
                    {
                        for (int i = 1; i <= pptshape.Table.Rows.Count; i++)
                        {
                            for (int j = 1; j <= pptshape.Table.Columns.Count; j++)
                            {
                                /// checks if the module of the current row and the amount of maximum
                                /// shown rows to be visible in table is the same
                                // Console.WriteLine("row= " + i + " col= " + j);
                                if ((i % amountrowsshown) == 0 && alreadycreated == false)
                                {
                                    PowerPoint.Table objTable = null;
                                    /// Add new slide if table requires more than one slide
                                    if (newaddslidecounter == 0)
