I am in the process of creating a program that is linked to a database. I want to automatically generate a reference number that is not already present in this database, to do this i know i am going to need to search the database to check whether that number is already present or not. But I am unsure of the best way to go about this. I am using an access database and vb.net.
View 8 RepliesIs there a simple method to tell whether a certain word is present in the webbrowser (not the source, but the visual stuff).
I can't use the source because it takes too much time to load when it's a rather large site page. And I believe I can't use instr on webbrowser1.HtmlDocument.
Who can point me in the right direction, I didn't find any solution myself with google. I only need to know if for example the word 'New' is present on this page, so a True or False must be returned
I would like to add a way to see if an entry is already in a connected database in the following code. If it is then don't add the entry and pop up a dialog saying something to the effect of "already been scanned" and if it is not, proceed as usual.[code]

I am currently trying to develop a program, for personal use, that will monitor the lending of items of music equipments to friends and family etc. And, for my program, I have a requirement, which is the ability to search a relational database, for items loaned, through my program, based on criteria entered in a set of text boxes located upon the program's form. I have already set up the form, and have searched the Internet high and low, to no avail (probably didn't look hard enough).e,I would also like to make another request... if possible I would like to achieve this task with use of the 'LIKE' statement, so that I don't have to input the criteria in full, when I wish to search the database.
The database that I am using is a standard Microsoft Office Access database, saved in a '.mdf' format, and the database comprises of three tables; LoanTbl (which specifies the loan details), EquipTbl (which contains information about the equipment loaned) and a LinkTbl (which forms the relationship between these former two tables) - the reason for the LinkTbl, even though it may seem unnecessary, is because the data has undergone 'normalisation', so that it is stored in the most efficient way possible.
Also, whilst I am on the point of linking together my program and database, does anyone also possibly have any ideas as to ways in which to add data to this relational database; I do have coding for this, however, it only applies to a stand-alone table, whereas there are relationships between my tables.
i am using visual basic 2008 with vb.net as language. i have created an application in which i am using oracle 9i sql database. the table is admissioninfo in which the columns are rollno,feespaid,dept,sem,sec. i want to know how i can search a record i.e, rollno from the database through my program and the program will show feespaid,dept,sem,sec in the textboxes.
View 1 RepliesI tried looking up Threads that would search through an access database, but I keep running into this:

The server returned an invalid or incomplete response.Is there any threads that would help me? For example, in my program if I wanted to search for a certain customer I would enter their info in text box and it would search through my Access database. I have all ready added the data source and even added a section where they could add in somebody to the database. But I can't seem to get the search part down?

I need to happen is for whatever is typed in the txtStockBookID text box to be searched in the 'BookID' field in the database (dbStratagem) and for all relevant records to be produced in the datagrid (grdStockResult).

I`m developing an appication which works with a mssql server database.At this stage I don`t have a problem connectiong to a database, because it`s on my computer.But the release version will be installed on few computers, when after installation user will have to choose the correct database to use with the application.

1. How to show databases availabale in th instance?
2. How to separate database designed for my application from all other databases in chosen instance?
how to add and remove entries from a database and now I need to know how to search it. I'm going to be scanning a directory and subdirectories and adding all files found to the database. I need to check if the file has already been entered into the database before adding it.
I though it'd be simple and would just require looping though each entry and checking the item for each entry. I played around with a while loop a bit and ran into some problems. Like when the database is empty.
I don't want to half-ass some code that seems to work, since that'd probably be slow and inefficient.
Also what are the technical terms for a column and row in a database. I'd to use the proper terms in the future.

results:
