I have an assignment where I have to develop a Windows application using Visual Basic .NET. From the form that I have designed, it should save all records in a table in a MySQL database. How should I do this? Here's what I've got so far:
Imports System.Data Imports System.Data.SqlClient Public Class AddMember
I'm trying to add a name of a product to a Textbox...the name of the product is stored in a database. Now there is a Combobox with number in them....1 2 3 ect. Now if you select one of the numbers it must display that product name?
I have a single form in Visual Studio 2010...in that form...
TextBox = txtSearch Button = cmdSearch DataGridView = GridView1 GridView1 is bound to a View, tblAccounts.
tblAccounts includes multiple columns, including a text field for 'AccountName'...this name can be in one of two columns.I'm trying have a user enter any part of an AccountName in txtSearch, click cmdSearch, and return all matches in tblAccounts to GridView1.
I have setup a page in Excel with several textboxes for data entry. I would like to be able to tab from textbox to textbox so I can enter this data as quickly as possible.
That code works to read the entry data and to recognise the correct data, and the incorrect. However, even if entry is correct, the error msgbox will appear (x times of how many records there are in file), despite being navigated to the menu. Anyway that the Else isn't triggered when data is correct. Also for it to appear just one instead of (x times of how many records there are in file.)
Back on my form with a ton of financial data entry textboxes but I want to have the data formatted at runtime, as I enter the data.I have a format declared as Public Const cFmtCurrency = "##,###,###" ' don't need decimal for the local China currency What would be the least compicated way to have these textboxes (19 of them) format the Long Integer values as I enter the data. I think a Lost Focus event would be silly; there must be a better, more efficient way.Also want to use this format when I retreive records from the db (don't see a reason to mask data in db)
When the user clicks to start a ticket I want to be able to display an autonumber from mysql that corresponds with the current ticket being filled out, so that the user can track their ticket later on. I have everything set up but I'm not too sure how I can display the Ticket ID in a textbox.
Right now I have it so that the query is being ran to get the next Ticket Id number when the form loads, but I'm not sure how to display it as text in the textbox.
'QUERY FOR NEW ID TICKET NUMBER Private Sub Suggestions_Load(sender As Object, e As System.EventArgs) Handles Me.Load Dim idQuery As String = "SELECT MAX(itID)+1 AS Expr1 FROM(TableName)"

How do you get a textbox being using for password entry to display the black circle that you often see in web forms, on the iphone etc etc?
I can change the PasswordChar property to an asterisk no problem and even copying and pasting symbols inserted into Word seemed to work - just couldn't find a symbol that looked like a bullet point!
Can this actually be achieved for a standalone exe, or is it something unique to web forms? Surely copying and pasting symbols from Word isn't actually the answer?

I'm creating a project for my brother's thesis for his VB subject.Now, the thing is, I'm trying to display row data from database to the (already binded) textboxes in form1. As you may know, this procedure requires that the program:
1. Declares an sqldatareader, sqlcommand, and an sqlconnection.
2. open the sqlconnection.
3. ....and use the sqldatareader to fetch the data from the source file.
The database file is made using sql server compact 3.5 and is located on same pc as where I'm making the program.The problem is, I'm getting stumped in trying to connect to the sql server. I'm getting a 26 error "error locating server/instance specified". installing sql server 2008 management studio to allow remote connections (which was already allowed in the 1st place), enabling TCP/named pipes protocol in the config manager, and enabling sql server browser service. I dont have spi firewall on since my isp has its own firewall on and xp fwall is off too. What I'm not sure about is my connection string as it might have been impeding me to connnect to server. How do I form out the correct connect string?

I am receiving RS-232 data from serialPort1.Readbyte and want to display the incoming data on a textbox on a form. This causes a "...cross thread..." error.
I been google search for a while (a month at least). My problem before is how to read raw data from access. however, i find out that access not suitable for my project. I more interested in using Excel, because for later analysis i would came out with graph using excel rather than using access. Since, i been develop a GUI Program for Battery Cyclic Test. The part for Cyclic Test and DAQ Interfacing is done already.
My weakness is not been able to understand/know how to read raw data for particular column, and display it into textbox. In many out there forums or discussion, they explain about this kind of database by using class in VB. But, i would like to implement excel data manipulation in VB-Window Form Application.[code]...
I am new to VB2008 Express, I have been trying to get data from the Serial port, i have tried for days to get it working. I have read lots of articles but most seem to be for Console applications and I am using an Application. All I am trying to do is create a form with a Textbox and this should display the data received from the serial port.
The data i am trying to receive is "ABC" on Com1 Can anyone either send me a project, as I am sure its something to do with how i am configuring it, or if thats not possible, show me in code?
I have a form with 1 DataGridView and 3 TextBox control which is txtName, txtAddress and txtDesignation. I have also MS Access Database Table with StaffName, Address and Designation. What I want is when I Double click firstrow DataGridView RowHeader.. the data from database will display in the txtName, txtAddress and txtDesignation respectively.. means StaffName for txtName, Address for txtAddress.
I am working on a project. Part of my project requires me deal with datagridview in windows form. I used 'Choose Data Source' wizard to display data from Microsoft SQL Server 2005 and into the datagridview. In my windows form, I have a datagridview with the columns - Email , CustomerNam e and Select. I also have a Add Contact button.
I have 2 questions which is:- 1) How do I insert checkboxes in the Select column 2) Upon inserting checkboxes in the Select column how do I display the rows, that I have selected using checkboxes in the Select column, to display into the textbox in another windows form?
I'm not sure how to do it, I keep on getting the wrong output.My required solution is to click a name from the combo box and display bits of information.How would I loop it so if one entry is smaller than the previous, it doesn't affect it?
Dim filename As String = "subject.txt" 'Declare where the text file is' Dim objRead As New System.IO.StreamReader(filename) 'Make objRead read the text file' Dim array() As String = System.IO.File.ReadAllLines(filename) 'Make array a string'
[code]....
Now I know this is definitely wrong, but this is only part of the program.
