Sql - Calling MySQL SP's With In And Out Parameters In .Net?
May 8, 2011
Mysql stored proc is
DELIMITER $$
CREATE DEFINER=`root`@`%` PROCEDURE `Check1`(
IN P_Name VARCHAR(50)
,OUT P_Id INT
[code]....
as various columns I need use VB .Net to call this procedure, insert value into the database and get the ID (primary key - company ID).Whenever I insert a row, I need to retrieve the ID. Right now, I am able only to insert the row, but don't know how to call a SP with both input and output parameters from VB.

I am writing a alternative to GDI, and rigth now i am working at a logging function. The idea is that while you use the class to draw, it will write a logg of what you have done, which can be used to draw it back later. In that way i would be able to store a drawing with weary little disk usage.

I am interacting with VB code on a different tier, using a client-side c# program. The VB function signature looks like this:
Public Sub toggleExclusion( _
ByVal mouse As Double, _
ByVal study As Integer, _
[Code]....
I get an error saying no overloaded method of toggleExclusion takes 2 arguments?

For the last couple of days I've been having problems inserting data into my MySQL database. I'm using parameters to insert the data and have done so in the past without any problems, but for some reason I haven't been able to get it to work this time.I have a form that the user inputs data to be inserted into the database. This data is then pushed into an array and sent to my class (CastProduction.VB) via a Public Sub. The data than pushed into a datarow and than pushed into a datatable. Once this is done I send the dataset and sql insert statement to a private sub that inserts the data into the database.

I'm program to handle ftp multiple file transfers. What I had in mind was to create an array for each type of file I need to process. There are 8 file types each needs to be transferred to a unique host.
' Each array contains in order: FILENAME|SOURCE PATH|DESTINATION PATH|HOST|USERNAME|PASSWORD
Dim arrA() As String = {"*a*.dat", "/destpath1/", "host1", "id", "pass"}

Let's say I have a MySql stored procedure that inserts a record with some nullable CHAR fields. In VB.NET if I don't check for Nothing (or Null in other languages), I get an exception from the db driver, so I write:
command.CommandType = CommandType.StoredProcedure;
command.Parameters.AddWithValue("_name", if(name Is Nothing, "", name)).Direction = ParameterDirection.Input;
And this is the first thing I don't like; I'd like to pass Nothing and the driver knows it has to put NULL in the Db. But then, in the stored procedure, I have to check back the field if it is empty:
INSERT INTO mytable
(name, -- other 200 char fields)
VALUES
(NULLIF(_name, ''),
-- other 200 char fields
)
I have to check for nothingness/emptiness twice. Is there a better, more direct, way? Even worse, for non reference types (i.e: Integers) the check for nothingness makes no sense, since a primitive type can't be nothing (yes, I could set an Integer to a non meaningful value, say -1 for a positive id, but...).

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.

I'm writing a query to select all records that has any part of parameter. I have one table called Employees. Some people have name like this: John David Clark If the parameter is
[Code]....
I should be able to get result back as long as there's a match in the parameters. If I use Function Contains (q.FirstName & " " & q.LastName).Contains(employeeName), I will not get any result back if employeeName is "John Clark" Function Contains looks only for next words from left to right. It doesn't match a single word at a time. So that's why I used this in the Linq to SQL:

Basically Commands has Parameters and parameters has functions like Add, AddWithValue, and etc. In all tutorials i've seen, i usually noticed that they are using Add instead of AddWithValue.

since it saves my coding time. So which is better to use? Which is safe to use? Does it improves performance?

I have determined thanks to the last q & a that there is something wrong with my "save to db" code as well as my "retrieve to picture" code. Even If I manually save the pic in the db it stil wont retreive. This is code i patched together from 3 or 4 examples around the net.
Dim filename As String = txtName.Text + ".jpg"
Dim FileSize As UInt32
Dim ImageStream As System.IO.MemoryStream[code]......

MySQL databases exists for saving values as strings (text only). Is there any way that i could store files with the same speed as a mysql command ? I know that it depends on the file size but lets say that the file is "Avatar.jpg" 50KB... I ve tried FTP but this is not what im looking for. e.g. You want your users been able to upload a file like the [Add This Attachment] button does in dreamincode.net and you dont have any background on PHP/HTML/Javascript/ASP.NET just VB.NET and the basics of MySQL plus you dont want to use it for a website. How do you accomplish this? Something silly that ive tried was opening an image as text then update the mysql server with that text but it didnt work backwards after i wrote the text on the file and oppened it ...it said that the image was corrupted.

What i have going on, is i have a MySQL connector as a resource on my application, and im basically trying to connect to my MySQL server, to either a) register a new account, or b) check that the account exists and they are premium, and login, Now what i have run into problems with is: My MySQL Database Name has a _ in it which VB is not allowing for some strange reason.
The code i am using is below
Imports MySql.Data.MySqlClient
Public Class Form1
Function UpdateRecord(ByVal query As String) As Integer
[CODE]...
How i can allow the _ into the application, because the only databases that don't have a _ in the user or dbname are a) Paid ones which i DO NOT have the money for or self hosted ones, i cannot leave my computer on 24/7

I have a query from within my vb.net code which searchs for a record by date. The date being entered via the code is in format dd/mm/yyyy, i need to search in the database using yyyy/mm/dd? Ideally i thought there may just be a function within MySQL which will convert this. If not in vb.net to convert the string 01/01/2011 to 2011/01/01?

I'm connecting to my mysql server using ODBC in vb.net, the database is shared throughout the company because it is used in an accounting program (simply accounting), each user has their own account user/pass to login to the database. I have developped a program that uses the accounting database and combines it with other information, my problem is that at least once a day I get this error when I run my program: "(10061) ERROR [HY000] [MySQL][ODBC 3.51 Driver]Can't connect to MySQL server on"and the error persists for at least 4 hours, for some reason it starts to work again later on in the day.

Now I have my databases in .sdf-files. These files are located on a server and loaded into several listviews. It has worked fine for a while, but I found out that last week one of the computers didn't close the connection with the database, which resulted in (a bunch of) errors on the other computers.
I have a mySQL server (external) where I can add the data into, but I think that it would slow down the loading severely, but it's very important that people can import the data at the same time.

I've got a project in c# which is making use of another project written in vb.net. I am currently able to modify both.I've got a method in the VB project like:
Public Sub MethodName(ByVal param1 As String, ByRef param2 As String)
param2 = param1 + 1
End Sub
I am not able to call this method using the out keyword from C#:
public void CallOtherMethod()
{
string param1 ="test";
string param2;
provider.AddTransaction(param1, out param2);
}
Shouldn't the ByRef keyword in VB.Net have the capabilities of both "ref" and "out"?
