First of all I would like to thank administrators/moderators of this site. When i was new to access database, i find best answers and solutions here most of the time. Now, i try C# programming language and have to find access database codes counterparts. Inserting record in C# i think is 10 times harder compared to access database. Textbox currency format, Using enter key to goto next control, Manage null values like nz() and so on.. Months of searching and browsing , i have not found a site like this.
