View 20 RepliesI have some deprecated code in visual basic when connecting to an oracle database. I am using a OracleDataAdapter but it says that this has been deprecated. Does anyone know what the new supported code is to connect to a database?
View 2 RepliesWell for some reason when i try to add a reference so that the oracle database can connect to the VB.NET 2010 program.In other words it shouldn't highlight certain code as if the database is not connected.Here is a clear summery as best as i can say what the problem is.
1. Connection from Visual Studio 2010 to Oracle plus server
2. Adding References will not be allowed for some reason.
3. The code (See example below on what it might be) is still highlighted even when i added the references several times.
I'll show just a small snip of the code coz it's more or less the same on most of the forms if i want to either update, delete, add or amend to the database. I'll show a few screenshots so to be clearer.I've tried by even looking over the notes and followed step by step and nothing works.Since i am not registered in this module this time i can't seek help of the lecturer so don't bother telling me to go and ask my teacher I've pestered the supervisor that i'd have to present this project to and she hasn't replied to my email at all so i have no clue what else to do in the matter.
I have a vb.net application that will not connect to an oracle database on the PC that I publish the app too. It works fine under my pc both in design and when I publish it to myself. But it will not connect under the pc I publish it too. I do have oracle installed on the pc and have the connection setup exactly as I have on my own pc. I am sure it is a file path issue, or at least I believe it to be that.

then send it to datagridview
I've the data in Datagridview (2 column - wavelength, absorbance) and i need to display in text box based on some reference. let say my first reference (soot it has wavelength value plus minus 2000 (range 1998 until 2002), 2nd ref NO2 plus minus 1630 (range 1628 until 1632) and others ref.
Firstly the system will find the specified wavelength in column1 (datagridview). if wavelength(column1) found in that range it will display the value in the textbox (column2- absorbance). then the information in the textbox, need to be save in oracle.
I am trying to create a console application that does the following:
1) read a text file
2) Save the content over to a SQL Server database
3) Use command line arguments to allow user to specify any delimited file
