VS 2010 : Adding Additional Records Listview Via MySQL?
May 20, 2010
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 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 (?,?, ?, ?,?,?, ?,?,?,?)"

Im practicing a database and I have a 3-column table. Im using binary formatting to save/open the file. I cant see what is wrong with my code“
I can display records ok when I press the save button
I can also save the records ok when the save/close button is pressed.
When I reopen the programme and press the reload button to reload the dataset, additional records will not be displayed nor saved though original records will be showing.[code]...

I am trying to search through records of my database in a VB form and I don't have any errors or warnings but it doesn't work.
Here is the code and a screenshot:
Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click
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 have records in my datagridview (from database(ms sql server 2008 r2)). What i want to do is to insert the records selected by my datagridview checkboxcolumn and IF POSSIBLE automatically delete a record if the records to be inserted are equal to the records inside the database. (Hoping you got what I want to say.) For example. I have an A,B,C(child) that is under XXX(parent) in my database and I'll be inserting the A,B(child) again but it will be under YYY(parent). The old record in XXX will be deleted except C. I just want a possible DELETE STATEMENT These are what I've done so Far :
Insertion of record to database
Try
connectionString = "Data Source=***;"
sql_connection = New SqlConnection(connectionString)

I'm adding records to my table which works fine. However, when I want to add a lot of records it takes some time and it looks like nothing is happening. I want to add a progressbar to show the progress.
For Each dgvrow As DataGridViewRow In mydgv.Rows
progress.Maximum = mydgv.Rows.Count

I'm am very new to Vb.net, I have coded in VBA.I have created a form that will open Microsoft Excel, add header text to the columns, and insert the text from a few of the controls located on my form ("not finished adding controls") when I click the Submit button.
My problem is that when I enter different data into those controls and click the submit button again, I get a new Excel Workbook with the new data.I need the new data the be submitted to the .Activecell.Offset(1,0) of the already open workbook.Ultimate Goal of Submit button is to open new Excel workbook, Enter multiple rows of data via Visual Basic Form.

I need to make a custom control and decided, before that, to see if there were any additional components that I could utilize.When looking through the list, I found a component called an Expander. So I decided to add it and see how it works.
After adding it, I couldn't find it at all within the toolbox. I went back to Choose Items and it was checked, but still not in the toolbox.It's probably important to note that it is a WPF component and this is not a WPF Project. Would that make a difference?Is there something else I may be doing wrong?

I am not able to add records in an Access 2007 database using VB 2010 Express Edition. I have read other posts and followed them but still I am not sucessful. I have the connection to the access database as MS Access Database, therefore it has the OLEDB connection (not the Jet 4.0). I am using the project instance in binding the text boxes to the fieldnames in the Access database. Did I miss something? I am also using Windows Vista Ultimate.
Below is the code.

I have a line of data that represent a data import. When the import is done, I would like to keep that exsisiting line, and add another line for the next import. So I have a display of mulitiple lines, showing multiple Imports.So this is one I have for the first section, it loops through the data so you see the rows incrementing
TextBox1.Text = clsDatRow.iFirstVal.ToString + " ROWS:" + iCountRows.ToString + " " + Date.Now.ToString
TextBox1.Refresh()
Now, I can I keep the line of data, and add a new line so for the next import, it does the same thing. It ried vbnewline, but it just clears that line, it doesn't move down to a next line.

I'm copying code from one VB project to another PC but the 'datagrid' on the copy insn't inserting into the new PC. When the form loads the datagrid is missing. The error I got was that there was something missing from the machine. When I tried to add the datagrid using the 'Additional Controls' it doesn't seem to exist. Any chance I can download the control? The version of VB is 6.5 and its part of a graphics package I'm using.

I'm running some if statement but I have hit a brick wall with what I'm doing and trying to do. If textbox1 has a value then I run different coding to if textbox1 and textbox2 have a value - Textbox1 will always have a value. [Code] What I'm trying to do is add an additional statement if both Textbox1 and Textbox2 have text, then to run code 1 if the last four characters in textbox2 ends in .jpg else to run code 2. [Code]

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'm sure there is an easy answer to this, and it may be "no," but is it possible to create an install file in VB Express 2010 and have that file deploy additional .exe files?
I developed a windows form program that calls fortan routines (in seperate .exe files) for different purposes. I would like to create an install file that deploys not only my VB program, but all of the supporting code.
Is this possible with VB Express 2010? I tried to search for threads about this, but didn't find any that explicitily answered this question.
