Use a linked object to dynamically add OLE objects to your presentation. This object could be an Excel worksheet or graph or for example a Visio drawing. The object that will be shown is deducted from the information of your data connection.

Click Insert > Object > Create from file in your PowerPoint menu. Check the Link checkbox and click Browse to select your default file.

At the Insert button you will get more options to choose from after clicking the small arrow in that button. Choose Link to file.

Click DataPoint > Linked object properties to continue.

Select an existing data connection from the list. These items are the data connections you have defined as data sources for this presentation.

Choose a column from the available columns list. These are all the columns that DataPoint could find in the defined data connection. The content of the column refers to the object you want to display.

Enter the row number of the record you want to use. Normally this starts with value 1 but in case you want to display multiple data rows on 1 slide, then you can put multiple objects on this slide and increment the row number for each new row.

Here you can specify what information can be found in the chosen Column field. This field will always refer to an object. This reference or path could be the full path to the object or file but it could also contain only the filename. In that case you can set here what the default folder is to look for the object.

Set Folder, filename and extension when your field contains the full path to the object. Folder and filename can be chosen when the full path is not including the extension of the file (e.g. jpg). When choosing Filename and extension you will be able to set the folder to locate the object. And finally the Filename only can be used to set the folder and the extension to a constant.

Click Clear to remove all DataPoint properties from the object and return to a normal and static shape.
