i'm trying to pass a variable between two datagrids. The first is on an main form, and the second is in a dialog form.
I tried using functions and also through public variables like this:
Invoice_new (Parent FORM):
Controls:
DatagridView: invoice_items
Public WriteOnly Property ValueFromChild() As String
Set(ByVal Value As String)

I have been trying to find and/or think up a way for data to automatically update a data table.I have a log that shows all the customers that came in today with various information. There could be twenty or thirty employees adding to this log or updating or doing things with that customer. This information is in a Data Table on a ASPX page in Visual Studio 2010 that the code is binded in the aspx.vb page that is calling a page in my APP_CODE database file that calls a query in my Database to get the information.My question is could someones actions on a different computer make my computer refresh or to re-bind that data.I have thought of some kind of timer/counter maybe that looks to see if the count of the log is different.
View 2 RepliesTry something along these lines:
TextBox1.Text=(dt1.rows(DataGrid1.CurrentRowIndex).item(0).tostring)
where dt1 is the datatable you're using as the data source and you want the data from the first column of the grid to be shown in the text box.

i have a data grid in my form.It has 3 colums.On clicking the second col I want to put a value of 1 in there.I tried using datagrid click event but nothing happens in fact the the program wont even go there.[code]
View 2 RepliesI'm curious what we all are using to display grids of data.I keep falling back to LISTVIEW's in DETAIL mode - they visually look nice to me. But I'm always writing code to load them from datatables and such - lots of work.DATAGRIDVIEW's - not so nice looking. Of course we can edit them easily - and they bind really easily
View 2 RepliesI have looked at the answers in the forum and some seem dated. I an an old vb2 person and need to move up. I understand sql very well and use complex queries. First test project and trying to add multiple tables to a data grid (Only Form in project).I used the Data wizard to add the Access data base and worked by way through to near the end. The query works in the wizard and returns the correct rows. The error message is "The solution returned by the new query differs from the base query."
During the creation process I selected all the tables. Reading some of the old anwsers I get the inpression that VB 2010 does not handle multiple tables in a datagrid (forum items go back to version 2008).
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).
Starting to design an application and wondering if its ok to have only one form as the application which could hold up to 15 gridviews separated in tabs etc. with a navbar as navigation on the left. Is this too much or ok? Is it better to have one gridview per form? What is the norm?

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 need to copy all data from a Table of a Acces mdb (connected with OleDB) to a Table of a MySql DB (connected with ODBC)
I made a working solution, but it's very slow, and so I want to try other solutions to check if they can give me more performance.
The solution connecting to the mdb, using a DataReader, then for each row in Datareader I make an INSERT into the Mysql Table ( before copy I truncate the table to get it empty)
The records are more than 10K and this operation is very slow, and do be onest I need to do the same thing on other 2 tables also very big as this one.
I cannot make a direct sql insert ( as INSERT INTO A in ..... SELECT * FROM B) because the 1 DB has a OleDB conn and the other has a ODBC conn.
So I thought to try to make this operation using TableAdapters and DataSet, but I'm not able to make it working.
The problem is that the Dataset's HasChanges is false
If you need some code I can post, but what I do is following:
Connection to MDb
Create OleDbTableAdapter
Create DataSet

View 11 RepliesPassing data between forms without any public methods or properties on the forms. everything but the "Controller" class, which I would like you furnish. I just changed the title from "Intermediate" to "Beginner" This solution is an example of the Observer Pattern. The "Controller" class is the "observed" class, which in this case means it publishes events.

The program should initially display Form1, and Form2. Clicking of the button on either form will modify the Title Text of both forms. I think that you will find the final end result to be pretty neat, as it works with any number of open forms not just two. I think asking for the Controller class is easier than asking for the code in the forms. My solution for Controller class has 7 lines of content, 9 lines if you include Class, EndClass. A minimal solution could achieved with only 4 lines of content, but it would a textbook example of bad programming.

I need to copy data from one database to another using a VB.NET program. The target database is SQL Server the source database is some proprietary ODBC compliant database.
I need to loop through a list of table to copy. Read the data from the source database table for a given modified date. Delete the corresponding date from the target database table and insert the records from the source table. The databases are of the same structure i.e. table names and field names, but the data types may differ (however they are compliant e.g. double in source, float in target). No primary keys exist.
Heres how I may do it :
Firstly execute a Delete command to the target. I could then use a DataReader to obtain data from the source, loop through the Items and create an Insert Command for each row. Add Parameters to the Command with the appropriate values and execute. And wrap the whole thing in a Transaction.
