INSERTING - Accepting Both The Forms Data And The TabControl Data
Jul 22, 2010
I am INSERTING into 2 different tables with 2 different buttons (One after the other by clicking each button). I have a form with 1 button directly on it to INSERT into tblCustomers from a field that is directly on the form as well. I then have a TabControl with another button with other fields (5 to be exact).
After I add data to the data base by filling out the field on the form and then by first clicking the add button located directly on the form and then add data to the fields directly on the TabControl the data will not INSERT itself into the tables in the data base for the 2nd table. Only the first table get data in it and not the one related to the TabControl.
BUT if i add data in the TabControl and then click the button on the TabControl it adds data into to the 2nd table. Is there a way to refresh my program so that it will accept both the "forms data" and the "TabControl data"?
I had all my fields on a form. THey became to many for the one form, so i moved them to a Tabcontrol. I split the fields over 5 Tabs. I did not change the code.Now , when i load the form, it does not connect to the data until i click on the tab. How can i fix this.
I am using VB.Net 2010 and SQL Server 2005 Enterprise Edition I have created a table named customer having columns (id int, fullname varchar(50)) and id is my primary key I have created a Class Library for inserting data into the customer table. to insert data I am using following code...
Public Function insertData(ByVal TableName As String, ByVal LinkToDb As SqlConnection, ByRef Adapter As SqlDataAdapter, ByRef DS As DataSet, ByVal MyArray As ArrayList) As Integer ' ----- inserts data into table Dim sqlCmd As SqlCommand
Quite a few threads on passing data from one form to another, but I'm struggling to work out how to share data between the two - back and forth.
For example:
Class1 is a class with 10 string properties
Form1 has 10 labels ("Label1", "Label2" etc) and a [Configure] button. Form2 has 10 textboxes and a [Apply] button.
I want to load with Form1, and create an instance of Class1. Click the Configure button and load Form2, passing Class1. On Form2 I want to manually fill in the 10 textboxes and hit Apply. The Apply should update the Class1 instance and close the form.
Form1's Label controls should then be updated with the data from the Class1 instance.
I'm fine creating the forms and classes, as well as passing the class into Form2 with a custom Sub New(EmptyClass as Class1) constructor. This gets the empty class into Form2, but how can I get the populated class back to Form1?
As Form1 already exists I don't want to create a new instance with another custom Sub New(PopulatedClass as Class1)
It's also key to be able to use the Form2 multiple times, basically ending up with a Data class being displayed as part of Form1 but updated using Form2? (For example if the Class has already been created and populated with data when it's passed back to Form2 for the second time I would pre-load the Textboxes with the values already in the class).
I am developing a program that will contain a TabControl on a form. The TabControl will have multiple TabPages that will represent forms used in the mental health field by clinicians. What I have done so far is created a SQL Express 2005 database that contains a table for each TabPage. To start off, I am working with only 2 tables to see if I can make this work. The tables are called EvalPage1 and EvalPage2. Each table includes a field called ClientID which I have named Key Indexes. I am also using these fields to create a relationship:EvalPage1.ClientID (Parent) and EvalPage2.ClientID (Child)
The problem That I am encountering is when I use the BindingNavigator to enter and save a record, it only works for EvalPage1 and not for EvalPage 2. Here is the code that I am using:

I have just started with vb and would like to know if there is a way to input several boxes of data on one form and display individual pieces of that data on several other forms at timed events in the future?
I am pulling data from one SQL Server database, formating the data and then inserting it into another SQL Server Database. I am looking for a faster way to do this than the one I am currently using. The data pull is about 37,000 rows, so formating it and inserting it one row at a time is very time consuming. I was hoping I could format it into a datatable and insert the datatable into second database essentially inserting all rows at the same time as if they wre within the same databse, but I have not found a way to do this.
Essentially the code (I have simplified it) that I am using... Dim cn1 As New SqlClient.SqlConnection Dim cn2 As New SqlClient.SqlConnection Dim cmd1 As New SqlClient.SqlCommand Dim cmd2 As New SqlClient.SqlCommand [Code] .....

I'm trying to find an easy way to export data from my database using VB. I already managed to write some textbox values into excel, but since this takes a lot of time and is not practical in my program, I need to learn how to export masses at a time...
So, I need to write 6 different values from the database table (shown in the picture in red) that are decided by 3 other values (shown in the picture in blue).
I have a Form1 where I can choose the "ProjHenkID", "Ty�Nro" and "Pvm:" (shown in blue)...
Started the code like:
Dim MyExcel As New Excel.Application MyExcel.Workbooks.Open("C:Tuntilappu.xls") MyExcel.Visible = True
but don't know how to call values from the database and insert them into specific cells in Excel...
