To do this we will use a database access tool called OleDbDataAdapter. Before adding appropriate controls to our form let us first establish a connection to our dbnames database file.

I barely know how to use them on text files, which leave us no choice but to do everything the lengthy yet easiest way. Though that may seem simple, it is more complicated to use BOF and EOF functions in Visual Basic 2008 than in lower versions of Visual Basic. The record pointer is continuously incremented until a match is found and the end of file(EOF) has not yet been reached.Īt this point we will now apply these pseudo codes into our search module. If the search text is not equal to the first record, the record pointer is moved to the next record and a search text is then compared to that record.Ĥ. If the first record is equal to the search text, a corresponding record is then displayed.ģ. That text is then compared to the first record or beginning of file(BOF). First, a search text is entered in a text box as an input.Ģ. To give you an idea of how to do it, let us first examine the common algorithm shared by most search modules.ġ. Perhaps there are other methods that I may not know but here’s an approach that I discovered through inquiries and experimentation. No wonder why most questions that relate to searching a record values in nearly all web forums are unanswered. I’d been using Visual Basic 2008 Express Edition for a while now but I can hardly find a method appropriate in searching record. Search module allows you to quickly test whether a specific record value exists in a multi-records database. As you may probably know, standard navigational buttons are only effective if you are managing few record values but when it comes to billions of records a search module is considerably significant.
