View 6 RepliesCombo Box Read Write MySQL?
Feb 25, 2009for starters not sure if this is the right place for the post considering that it includes MySQL and VB, its here.I'm trying to load data from one table into a combo box as the data you can select, this i have been able to do "tbl_Wind" using "WindDirID" and "WindDir"
also, I am trying to select (if it exists) a value from "tbl_date" "WindDirID" to select a value from the existing data in the combo box loaded from "tbl_wind"and finally, I want to be able to change the value in the "tbl_Date" depending on if a value is selected in the combo box.when a new record is created in tbl_date it uses default values, so there is always something in the field.below is about how far i got, and its the only part that works (extracted and edited of course to exclude the other queries)

Apr 6, 2010So, what I'm trying to do is to connect to a remote database using the MySQL connector. Dim c As New MySqlConnection c.ConnectionString = "Server=" & URL & ";Database=" & "" & ";Uid=root" & ";password =" & "" c.Open()I know the connection string is correct. I can access the phpMyAdmin through a web-browser just fine. For some reason however trying to open the connection throws an exception 'Unable to connect to any of the specified MySQL hosts'. I tried disabling the VS debugging process, as I thought maybe it's blocking my MySQL access for some reason, but no.

VS 2010 - MySQL Connector As A Resource On My Application - Connect To My MySQL Server
Jun 21, 2012What 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

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

Application Can't Connect To Local MySQL But Can Connect From Command
Sep 30, 2011We have a VB.Net application which works fine in our tests in different Windows XP SP3 machines. However there is one machine in which is displaying this error:
Unable to connect to any of the specified MySQL hosts
Using the mysql command, we can successfully connect to the database. We already checked for any other application or firewall that could be blocking the connection but it seems fine. We also reinstalled the system (no errors during the installation) but the MySQL error message doesn't change.
The system settings are exactly the same as in the other computers. We are using "localhost" as server in the connection string. The "hosts" file has its default values (nothing strange in there).

Read/write Some Data ?
Feb 13, 2012My first question has to do with the opening lines needed in a VB program in order to connect to Excel 2007 and read/write some data from/to it. I know the process only slightly and reading and writing to the cells is not my real concern for the moment. What I need to become familliar with are the lines like this:
CODE:
This is just one of the examples I have read through and to be honest I only follow this slightly. The trouble was that with each new article I read, people did this differently, not the variables on the left mind you, just that some left out lines, which I can see could be done based on circumstances. Still others said the Imports line was not needed....etc...and other loaded up at least 3 or four more Imports lines insisting all were needed.
I'm looking for some straight-forward advice on what is the minimum needed to access an existing Excel spreadhseet and to just read some of it's cells to variables in the code and then writed some data back to certain cells within the spreadsheet and then save and close it.
Also, please note that I am using VB 2010 Express. Why, because I'm a broke developer who spent most of last year out of work. I have a new contract assignment which is so far going well but will go even better if I can master this technique with VB.NET, not VBA. And all the docs I've read said that even though VB 2010 Express is a watered down version of VS, I should be able to do medium level tasks such as this with it.

Read / Write Data From RS232 Port?
Aug 23, 2010I need to write and read data from a RS232 port. On the RS232 port there is a RFID Card reader-Writer connected. So I need to send hex codes to the device, and have to poll every 1sec if there is a card in the system. If there is a card I need to read the info that is on the card. My biggest problem is I think is that I am not sure how many characters there will be in return after the read command (maybe it is always the same length this I am not sure). What is the right way to read-write to the com port. So I always got the same result and not skipping a code.

Read From CSV File, Write Directly To Data Source
Sep 7, 2011I'm trying to "convert" an Access DB to a stand alone application. I have under estimated the differences between VBA and VB. Although I have many questions, I'll focus on this topic first.
The Access DB collects and maintains SNMP traps from a radio station. I import CSV files from a remote Unix server via FTP, parse the text line-by-line, and add to a table as a new record. So far, I can parse the text and add to a dataset but I want to write directly to the data source. I also need error handling that will trap errors for duplicate records. There is a Reconcile function that ensures that all lines in the CSV files are added to the table before the files are permanently deleted. Here's what I have so far:
Public Class clsRnm
Private msTrapTable As String
Private moTrap As clsRnmTrap

Write Code That Will Control And Read Data From Applications?
Mar 22, 2010I'm having difficulty figuring out how to run different programs with my VB program. Using Excel and other MS office programs is easy enough since I just add in the relevant COMs, but I can't for the life of me find out how to run other programs. I promise I spent many hours searching before bothering you kind folks here! I'd think this is a common issue so maybe I haven't been searching for the right thing.how to write code that will control and read data from applications.I know you can do "Process.Start" to open any application, and it looks like there are ways to determine the controls available on an open application, but I can't figure out how to do it. Is this possible? Or do I have to import a .dll file for every program I want to control? Or are both possible?
