Ado.net - Execute A Stored Function In Oracle Or Sql - Adding The Parameter Values Of The Function

Dec 13, 2011

I need to execute a stored function in oracle or sql through vb.net. I created a command object. Depending on the database type(oracle or SQL) i am preparing the Command text as Select functionName(?,?,?,?,?,?,?,?) from dual; (For Oracle) Adding the parameter values of the function. Now performing the ExecuteScalar which is not working saying invalid parameter. This works with ODBC connection string. But ODBC doesn't with 64bit. My Requirement: Code should execute a user defined stored procedure by taking the values at runtime.

How To Pass A Function To A Function Is Functors/function Objects Avaiable In VB2010

Oct 12, 2011

I want to make an numerical integration method with takes in an analytic function and integrate it over a specific interval. For the numerical integration procedure I want to use some procedures in nr.com. The problem is that these are programmed in C++ and they uses functors to pass a function to the integration method. How can I do this in VB 2010?

I want to initialize the function (i.e. set a=1,b=0 for function y(x)=a*x+b) and then pass the function to the integration method. Then when the integration method call the function it only calls the function with one parameter (i.e. x since a,b is already set)

What is the best way to do this in VB2010?I want to make a general integration method where I can pass any single valued function and integration limits.

I have just started using VB, and from what I have found so far it seems like the tools you have is

- to us a delegate for the function
- to use a lambda expression for the function
- send a pointer/adressOf
- to create a function class/structure and submit this to the function

As for now I am most inclined to create a function-class. But I am not really sure how.F.ex. I make different classes for each "uniqe function" I want to integrate, but how can I pass them to the integration function when I need to specify the argument type in the integration-function-call?This seems like a basic problem which applies to many Math operations, so I think it would be very useful to clarify this.

Function Syntax - Call A Function With 2 Arguments When The Function Is Only Defined For One

Apr 1, 2010

I'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net. Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.

My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for

Here's my call:

<script type="text/javascript">

function HelloWorld()
{

var yourName = $get('txtYourName').value;

Replace Function Runs Out Of Memory?

Apr 18, 2012

I don't use VB.Net very much, still mostly do VB6, but I am doing this project in .Net. I have a huge string of data, 168 Mb that I stream in from a file to a string variable. Then I have to perform a number of replacements on it before using the data to compile statistics. Because of the nature of the data, I can't break this up into smaller strings.

The problem is that I get a system out of memory error after a few replacements.

I've used both Replace(x,y,z) and X.Replace(y,z). The second one gets a little farther in the code before it crashes, but they both crash.

When I run it in the IDE, the IDE is using about 130 Mb of RAM, the Exe of the app is running about 350 Mb, and one svchost.exe runs about 300 Mb

Other than that there are no major RAM uses going on. The PC has an i7 980x cpu with 12 GB of RAM.

VS 2008 Memory Leak In Short Function

Nov 9, 2009

I have this relatively short function, triggered when the mouse is moved over a picturebox. When being called, it slowly increases the RAM and PF usage of the program which never recovers.[code]I just wanted to report back and say that I did solve this issue (more or less).I added a manual garbage collection call at the end of the loop and it kept the resources usage under control. It did seem to slightly slow the response time, but it's worth it to avoid the program hogging multiple GBs of RAM.

ASP Function That Returns Result From Stored Procedures

Apr 15, 2010

I am working on a project that requires me to hop into to separate DB's. So I have figured that I need to have multiple functions inside of my VB page. The only problem I am having,is I am not to sure how to get this all accomplished. So far I have figured out the overall structure, just need to implement that structure.

Here is my idea:
The main Function would call two other functions. We can Call them Sub Function 1 and Sub Function 2. So, the main Function takes the saved sessions information for the E-mail address and dumps in into Sub Function 1. It needs to open up a new connection to the db/stored procedure and RUN the following procedure and then return the result. Here is the stored procedure and what I think is correct.

CREATE PROCEDURE WEB_User
(@EMAIL_ADDRESS varchar(80) = [EMAIL_ADDRESS])
AS SELECT MEMBER_NUMBER
FROM WEB_LOGIN
WHERE EMAIL_ADDRESS = @EMAIL_ADDRESS

So my question is, what is the function suppose to look like? how do I send the session information to the procedure? and finally, how do I return the stored procedure results and push back into the main function so it can be carried into sub function 2?

Call An Oracle 10g Stored Function Not Procedure

Nov 10, 2010

I've been trying to figure out how to call an Oracle 10g stored function and insert the return value into my VB.NET application. Stored procedures I've been already able to figure out, but I have no idea about functions.I have the parameter set to send to the function, the oracle function works perfect, but what VB coding to I need to get that return value. The return value is a CHAR.

Again the Oracle DB is in their 10g release.

My version of VB.NET Is Visual Studio 2010.

Also I've beent trying to use the Imports System.Data.OracleClient namespace but it comes up with an error saying its not available. Right now I use System.Data.OleDb. How can I import the oracleclient?

Measuring Memory Consumption Of A Function That Accesses A Database?

Sep 16, 2011

I have a VB Function (in Visual Studio 2008 with .NET 3.5) that opens up a connection to an Oracle database and queries the database for information. Apparently after some trial and error, I discovered when the SQL statement is being processed and filling the dataset, it apparently is taking up too much memory trying to complete the task. I'm running into System.OutofMemory exceptions and other unpleasantness.I'm wondering, is there some sort of program out there to measure memory consumption of your SQL code that is being processed in a Visual Studio application?

Setting A Variable To Accept The Result Of A Function By Calling The Function With Many Parameters

Feb 17, 2011

I'm currently working with a client's VB.Net code, which was developed for them by a small development shop a few years ago and which they purchased and have been maintaining and uprgrading since. This client's primary developer is out on indefinite (likely permanent) medical leave and I'm now filling in until they bring in a full timer (as I'm a contractor here). My current task is to add some functionality to a the VB.Net code they purchased. I'm finding practices and techniques in the code that absolutely baffle me and can't make the code do what I want. I'm starting to wonder if it's me and was hoping to get some thoughts on the code I've encountered.

For example: Setting a variable to accept the result of a function by calling the function with many parameters, clearing the parameters in the function, setting them to some value, calling another function with those new values, then never using the values returned by the functions. I'll add a code snippet in the first comment since this is already getting long.
