    1. COWhere exactly are you getting exceptions 2 and 3? I remember getting those exceptions while working with SQL Server Reporting Services building reports full of images. The exceptions fired after the process tried to consume more than 2gb of memory on a 32bit Windows install. Remember that processes are limited to how much memory they can address (no matter how much memory you actually have in your computer). Also, you might want to look into disposing your GDI objects. I've worked with unmanaged GDI+ before and you need to clean up after using the objects.

    2. CO@Ernriquein I get those error after processing of some file, let say the folder contains 30 images, after processing 17 images it gives this error. i have 64 bit windows 7 installed.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
