Feb 27, 2011

I am trying to make a very simple program that connects to a MySQL database using VB.NET. My program only has one form and one label. I setup my MySQL database to have a table and one field (a VARCHAR)called "Tab1". I manually inserted the value "CLOSED" into the Tab1 field using PHPMyAdmin. I want my program to change the value of the field to OPEN/CLOSED and I also want the label text on my form to change too when it's clicked.

Mysql Functions - SELECT Statement And Make A Function ?

Jul 12, 2010

I am trying to clean up my code a bit.

I made the following function:

Public Sub sqlUpdate(ByVal table As String, ByVal column As String, ByVal var1 As String, ByVal column1 As String, ByVal var2 As String)
Public CN As New MySqlConnection
Public cmd As New MySqlCommand

[CODE]...

Which is fine, if I want to use mysql update all I have to do is call something like: sqlUpdate("test", "test", 0, "test", test) I was wondering if I could do the same with the SELECT statement and make a function. I cant think of a way to do it though...

sqlConnect()
Dim cmd As New MySqlCommand
With cmd
.CommandText = "SELECT * FROM users WHERE username=""" & lblAccountName.Text & """"

[CODE]...

The data I would want to extract would be different every time.

Use AJAX With Aspx Backend?

Apr 5, 2011

I have to use VB.Net. Microsoft provides black magic tools (in the Visual Studio IDE) for making AJAX work, but using these seems hopelessly complicated and documentation for these tools covers only the simplest examples. By contrast, writing the scripts myself seems much easier, and I will understand what is going on.

So my question is, is it possible to write my own AJAX javascript (creating the XMLHttpRequest object, etc.), and have the server-side function be written in VB.Net instead of PHP?

Make A Program That Takes Old Records From Access And Moves Them To MySQL?

Feb 2, 2012

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".

Imports System.Data.OleDb
Imports MySql.Data.MySqlClient
Public Class Backup

[code]....

So now after my 3rd edit and no answers, I'm finally at the point where I'm only stuck on my For..Next statement not working, How can i get this statement to run for each 24,000 controlnumbers?

VS 2008 Make MySQL/DataTable Handle Norwegian Characters?

Oct 4, 2009

I'm populating a DataTable from a MySQL-server. One of the columns contains norwegian characters (�, �, �), but they don't display correct in my datatable. I've been searching google for some answer, but I haven't found any. I've never had this problem before. Actually I'm not quite sure exactly where the problem is. It's either in the datatable or in the MySQL .NET-connector as far as I can tell. If I do the same query in the MySQL Query Browser, the characters are shown correctly, so it can't be the server.

Can't Send Cookies From Page To Php Backend

May 16, 2011

I'm trying to create a proxy for cross-domain AJAX POST queries and, in order to do that, I need to be adding the cookies from my client (browser)'s request into the POST request I send to the PHP backend, which is using HttpWebRequest. In order to do this, I'm adding each of the Request.Cookie into the HttpWebRequest.CookieContainer object. For some reason, none of the cookies I add to it ever get to my PHP backend.

I understand from some searches that the CookieContainer object is URI-dependent (I'm not sure how to even explain it!), so perhaps that's the cause of my issues. However, I've tried setting the domain on my cookie to different things and it doesn't seem to affect it. So maybe URI means something different than the Cookie's Domain parameter. If that's the case, I'm stuck.

I'm really struggling here - I'm trying to create a connection string to my TD backend and this is not working unless I create a data source in the project and enter my username & password.

I keep receiving the error:"No error message available, result code: DB_E_ERRORSOCCURRED(0x80040E21)" [code]

Admin Backend Approve / Reject Content

Mar 7, 2009

I'm creating an admin backend on my site. All the user content that goes on the site will be stored in a database table called Pending. There are other tables where the content will go once approved (Guestbook, Quotes) but if the content is rejected, it'll just be deleted.I know how to delete the content from the database, but I'm having problems will the approval system.On the approval screen, the admin will see a DataGrid that's databound to the Pending table. There's a button that the admin will click to approve the content (based on a checkbox selection or input of a uniqueidentifier entered into a textbox.Can anyone give me an idea on how to move the content from one table to another? Some sample code would be very nice.I'm using VS2005 with SQL Server 2005 Express.

Backend Server Detection After Project Deployment?

Mar 30, 2010

I have recently learnt vs '05 and am creating a project in vb.net '05.my question is-During project development, we connect it to MS SqL server 2005 express installed on my system and it works.( I use add datasource wizard,add sqldataadapter,add gridview control,generate dataset,connect dataset to gridview method). But after the project is finished and we create its executable, the project will be run on adiffrent machine with a different server name and hence a new connection string will be required.

How can i make my project detect server details and connect to it, at runtime ? because the user is only expexted to start the server and open my application.the app must connect to the new server on its own. If anybody has an answer or if you know some resource where i can find it, please post here. Any suggestions are welcome.

Connect A VB Frontend With A Python Backend Using Sockets?

Oct 26, 2009

I have some really nice Python code to do what I need to do.I don't particularly like any of the Python GUI choices though. wxPython is nice, but for what I need, the speed on resizing,refreshing and dynamically adding controls just isn't there. I would like to create the GUI in VB.NET.I imagine I could use IronPython to link the two,but that creates a dependency on a rather large third-party product. I was perusing the MSDN documentation on Windows IPC and got the idea to use sockets. I copied the Python echo server code from the Python documentation and in under 5 minutes was able to create a client in VB.NET without even reading the System.Net.Sockets documentation, so this certainly doesn't seem too hard.

Excel As A Database Backend To Load Into A Datagridview

Mar 8, 2011

I'm using Excel as a database backend to load into a datagridview.

This is how I connect and bind to the dgv:

vb.net Dim sFileName = filelocation & "checks.xls"
Dim connectionStringTemplate As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=""Excel 12.0 Xml;HDR=Yes;IMEX=1"""

[CODE]...

It connects and populates fine. I have a button for the user to "refresh" the datagridview. I cannot get it to correctly refill the dgv. I have tried setting the bindsource.datasource to Nothing along with the datagridview datasource, but I get an error that brings up the Visual Studio debugger with no real error message...
