VB 2010 Express - Create A Simple Local Data File On PC Using Mysql
Jul 15, 2010I have been reading about ADO, SQL, datasets, data adapters etc and have gone into information overload. My next step is to create a simple data file of my own that I can manipulate, update, sort etc in VB Express. Do I need another piece of software? I read about MySQL, which I understand is primarily used to access databases on the net, but can that be used to create a simple local data file on my PC? Can you simply hard code something in VB Express?
View 6 RepliesMySQL And VB 2010 (.NET/Express)
Mar 8, 2011I am trying to connect my application to my database that's hosted on my website through another host. I am using the System.Data.SqlClient Namespace, and I have tried about every connection string possible, and I either get a long delay (About 30 seconds) before the main form displays with a warning in the Console box or it just gives me the warning and loads fast. Either way, it's not connecting.
code:
The x's represent just a masking. The server value is the ip address of my website. Basically, I am wanting this app to connect to my database of my website and it will be used to compare login information as well as the status of the logged in account (blacklisted, active, or needs to be activated).
Accessing MySQL Database Through 2010 Express
Sep 16, 2011I am trying to follow this userguide url... to basically build an application that will allow users to connect to my database, from an exe file. I'll try to explain as best i can. The plan is, users will launch an exe file that i have built in Visual Basic(VB) 2010 Express. When they launch the application they will see a 'login screen'.I am following the example guide (see link above), and will customise it once i can connect to the database. For some reason whenever i connect to the database it gives me two errors, the first is if i use the 'debug' mode in VB to test the script (note it doesn't produce any build errors), the second is if i build the application and run it as my users would.
1)Error Connecting to Database:Access denied for user 'mike'@'92.**.**.***' (using password:YES)
2)Error Connecting to Database:Unable to access any of the specified MySQL hosts..The ip address starred out (*) is my local machine ip address.The server is the server in which my Database runs on. 'mike' is a listed user on my 'user' table, the password i use is the password assigned to this user on my table.
3)I've rebuilt the whole VB project, but still no joy, wern't expecting it to as there were no errors generated.
4) I've read, but don't really understand that it could be something to do with my database not being able to be controlled remotely, only locally. I started digging into 'Access Your MySQL Server Remotely Over SSH', didn't really know if i was going completely off the mark, it didn't mention needing to do any of this in the guide i've been following, but just a thought. It might be the case as i've tried to access my database through a programme called MySQL Administrator. I punch in the host,username etc and connect to my database, for some reason it won't allow me to add new users, could this be because i can't control my database remotely? Would this stop what i'm trying to do working?
5) When trying to install the MySQL.Data.dll file i had great difficulty in choosing one and finding it, adding it to my project using the 'Add reference' in VB. Finnally got it how it should be (i think), installed MySQL.Data.dll Ver 6.1.2.0 into my project.

2010 Express Data-set / Data-view With XML
May 11, 2011I am a co-op student learning vb.net and I have a project which retrieves data from an xml file within the program (based on selections made from combo boxes) and calculates and displays prices.[code]I have one combobox that loads data from the Processes section just fine, but then another uses the same method and gets an "IndexOutOfRange" error or "Column AB12345Bed_Size Not Found" even though I am using the same method for both. For "Processes" I am using DataView.Sort on "<12345Material_Process>" which reflects the selecteditem in the combobox. The program retrieves that row without a problem. [code]

View 2 RepliesPrinting Data In Express 2010
Aug 2, 2010I'm trying to print from VB Express but it seems to be so difficult. I tried the printform component only to see the end result being blurred. I have data in one table (which will be used as the header) and data in another table (the body) which I need to print out. Seeing that the express edition does not have any reporting capabilities, I turned to several other open-source projects providing "free" reporting tools, such as MyNeoReport. MyNeoReport is acclaimed to be so good but the developer lacks a detailed tutorial for it. And the tutorial's I did manage to find are all in C#. Not helping.
How do I go about printing the data? The design is simple. Extract the company information from table A to display as the header, extract the body from table B to display as the results. I also need to calculate the totals of the body and add it to the footer or bottom of the report body. I can't seem to find any relating forums or questions similar to mine on any forum. Currently on the form, I've got a few labels, textboxes and a listview. I know I need to load the filtered data into a data grid at some point.
Is it possible to give me a detailed example of how to do this? I'm really frustrated with this whole printing thing. I don't have the finances to buy these other reporting products and the one's claimed to be free all comes with a price-tag in the small print.

View 3 RepliesFilter ComboBox Data [2010 Express]?
Jan 7, 2011I have started a form application using visual studio 2010 express, vb programming. I'm using Access as my database.My goal is to have ComboBox1 display a ProjectID and ComboBox2 display a TestNumber. Once the Test Number is selected I want my textboxes in the form to display fields from the row that the selected Test Number is in.I have 2 tables set up right now "Projects" and "TestData". The "Projects" table has a [ProjectID] field, the remaining fields are just misc. project data. The "TestData" table also has the [ProjectID] field, and then the [TestNumber] field, then the remaining fields are misc. data.
Filling [ProjectID] in textbox1 is easy, in the properties I select DataSource from the Projects table, display [ProjectID] field. Where I'm having troubles is ComboBox2 displaying the TestNumber from the other "TestData" table. If I select that field, it fills the ComboBox with EVERY TestNumber there is. So for Project 1 there is a test 1... over 500 projects, that combobox lists 500 Test 1's, no way to tell what project it belongs to...How do I make ComboBox2 only display Test Numbers that pertain to the Project number selected in ComboBox1?Using this code I can get it to work:
Dim ProjectNo, SQLString As String
Dim dtTableData As New DataTable()
Dim dbDataAdapter As OleDbDataAdapter
[code]....
I also imported system.data.oledb Problem with this code is it will only filter data in ComboBox 2 but when you make your selection from ComboBox2 it won't activate the row so none of my databinding textboxes fill anymore. Before the code/query is ran it fills up the textboxes perfectly after every selection I just have no idea what project that report number belongs to because the whole field is displayed in the dropdown. I can fill the form with ComboBoxes and they display the corresponding row data because I use a "datasource" instead of textbox "databindings" but I don't want to use 20 comboboxes as my entry form...
VS 2010 Using VS2010 Express / Best Data Type?
Dec 16, 2010I'm working on a small project - a database program to track and log the progress of some experiments. I'm using VB 2010 Express, and I'm pretty much just learning as I go. I'm getting ready to learn about the data models available, and am having trouble navigating the info I find.Is it best to develop the data within the SQL CE environment, or does that require the end-user to download additional libraries/programs? Is there a better data model for my needs (not much complex data processing, but a sizable amount of records/tables)?

Connecting To An ODBC Data Source In VB 2010 Express?
Jun 20, 2010I need to connect to an MySQL database in my VB.NET application (VB 2010 Express). When I attempt to use the Data Sources wizard to establish the connection, it does not provide an ODBC data source. I'm using Add New Data Source/Database/DataSet/New Connection which shows the Add Connection dialog. The only options it gives me for data sources are Access & SQL Server and the OLEDB data provider. It does not appear to give me the option of adding a new data source provider. Attached is an image of my current Change Data Source dialog. Where do I get the ODBC data source provider and how do I install it into Visual Studio?
