I'm working on a vb.net application that executes an Oracle stored procedure. The stored procedure displays a value using dbms_output.put_line. How do I retrieve that value from the oracle database into my vb.net code?

I have some stored procedures to execute that use dbms_output.put_line() to put data into the output buffer.I know I need to use dbms_output.get_line(:line, :status) to retrieve that output.I'm using ystem.Data.OracleClient to avoid headaches with Oracle deployment.So what am I doing wrong with the code below?
Dim cmdSproc As OracleCommand = cnOracle.CreateCommand()

View 2 RepliesI 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.

View 2 RepliesI am in need of a small application, that will allways be topmost and will send keystrokes to the last active application (typically notepad or an explorer window). My problem is retrieving the current active form (or application), when my application is started up. Every search seems to return old and rather complex solutions using Win32 library functions, but I was kinda hoping, that .Net allowed for a neater and more simple solution.I need a code example or link on how to retrieve the currently active application window from another application just starting up.
View 2 RepliesCurrently working on a web-service with Oracle10g as back-end. Here is my problem.
1. The table I need to populate has 100 columns. I have no control over the design of the table.
2. I wanted to use the "deriveparameters" method of OracleCommandBuilder, but found out that this is "costly" in terms of performance. What I initially planned to do was to derive the parameters from an open connection, close the connection, then maybe cache the parameters obtained but I don't know if this is possible.
I am unsure how big of a hit the performance will get if I continue using the "deriveparameters" method WITHOUT caching the parameters driven. The environment is as follows
-intranet
-around 2000 users
-users spread out in different parts of the country
I am not familiar where they will put the web pages of the application, the web service and the database. I don't know if they'll be putting it in different servers or on one server, but that's something we cannot control too, that's why I am looking for the best approach.
I just don't want to hard-code all that parameters and if, for instance, we need to change some properties/parameters, it will be a pain to maintain the code. It would be nice if someone here can point a way to automate the whole thing w/o the performance of the system taking a hit.
I want to (SQL) select from a table in an Oracle database, and show the results of the query in the VB application, in a Excel like manner (rows, columns, selectable, etc.). Or in a SQL developer manner. How can I do that? Browsed through a lot of tutorials and howtos on the internet, did not get anywhere. I think (and correct me if I am wrong) that it's gotta be something with DataGridView. But I don't know how to create and populate a datatable with the result of as Select statement, how to create a dataset.

I need to retrieve the actual text of a message box from another application. When using WM_GETTEXT, the values returned are the title of the message box, and the text of the control button (in this case "OK").
My issue is that what I really need is the actual text message from the box itself. I've been researching this for days and can't find a way to do this. Nothing I have found so far tells me how to do this.

I'm using VB.NET in Visual Studio 2008 in a Vista 64-bit OS. I'm trying to find an easy way (there must be one) to quickly retrieve from the registry the application file name and path to use in a Shell command to open a particular file. Specifically, I want the user in my app to be able to click on a PDF file and have the app open that PDF file using the application associated with PDF file types - Acrobat Reader, for example. Anyone have any suggestions as to proper coding & syntax for the following sequence?:
(1) Get name of .exe file associated with .pdf file type (most likely from the HKey Root Classes hive)
(2) Get path for the .exe file
(3) Shell("[pathname]appname.exe filename.pdf")
I've spent a couple of hours looking through the forums and haven't found what I'm looking for.

I am a biologist and I have a collection of dive data. It is very simple data...just time and depth (m). However, from each data set, I need to retrieve the onset of the dive, onset of the bottom phase, length of dive, etc. For years I have been finding these points through visual inspection of the data. It is extremely tedious and in know way efficient. I am interested in expediting this whole process and am more than willing to learn VB...but only IF it is the best approach for this application.I have attached two dives worth of data, so we can see what the data looks like. Each data set can contain from 1 to 8 hours worth of data.
