Get Records From MySQL Using PHP And Send It
Sep 18, 2011
I have a PHP script which accepts an argument and adds record in the mySQL database if its not available and if its already available it gives a message 'Record already found'.How can i read this message from vb.net and do appropriate action such as if data_is_in_db then msgbos("your record already found in the database")if data_is_not_in_db then msgbox("your record has been added in the database")

I was asked to create a program that inserts records into one parent table and multiple child tables. My question is, how do I know what the PK is for the parent table, so that I may add it as a FK in the child? The PK for the parent is an auto number. As I stated in my title, I'm using VB.net, mySQL, through an ODBC connection. I have to do this through the code and cannot use stored procedures.
my transaction looks like this:
Dim cmdText As String = "INSERT INTO candidate(first_name, last_name, phone1, phone2, email1, city, " _
& " state, country, zip,primary_contact_id ) VALUES (?,?, ?, ?,?,?, ?,?,?,?)"

Dim search As String
search = boxSearch.Text = txtSearch.Text & "'"
Dim foundRows() As DataRow
foundRows = taxDS.Tables("Orders").Select(search, boxSearch.Text)
End Sub
txtSearch.DataBindings.Add("text", taxBS, boxSearch.Text)
boxSearch.DataBindings.Add("text", taxBS, boxSearch.Text)

I'm loading my listview with records from a mySQL Table, which works great. But I'm having issues when I try to add records to another listview according the selected row in the first listview.
vb.net
Dim mysqlDataComm As New MySqlCommand("SELECT jan, feb, mrt, apr, mei, jun, jul, aug, sep, okt, nov, dec FROM data_table WHERE datum ='" & frm_main.Listview1.SelectedItems(0).SubItems(1).Text & "'", mysqlConn)Dim mysqlReader As MySqlDataReaderTrymysqlConn.Open() With frm_main.lstv_data.Items.Clear() mysqlReader = mysqlDataComm.ExecuteReader While mysqlReader.ReadDim lvi2 As New
[code]....
It works until ".Items.Clear()"... after that nothing happens and I really don't know what I'm doing wrong. No error, whatever.

I'm trying to make a program that takes my old records from Access and moves them to MySQL. Its supposed to take records from 3 different tables in Access to 3 different tables in MySQL. The first table is "Orders" and it sorts the ones to pull to the dataset, taxDS, by "Where Status = 'Waiting Payment' OR 'Cancelled'". Then the second table pulls its info(this is where i'm having trouble) by the "Control_Number" in the "Orders" table, so basically if the control number isnt already in the dataset its not going to pull the data into the new table "FNF Taxes".

Currently I have been using mysql connectors to send and retreive information from my database. Someone suggested that a web service (wdsl? etc) would be a more efficient way of sending information both ways.

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.

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.
