How can I add data to SQL Compact Database from DataGridView?Striving to do my best.
View 2 RepliesI am new to vb 2008 and I can't seem to figure this out.
When I try to add a database to my project I get this error (Please look at .jpg (Firsterror)
I have selected the correct driver SQL Compact 3.5
It will add the database to the project but the FULL PATH is always incorrect and I can't change it. (Please look at my seconderror.jpg) the correct path is C:SQLSample.sdf
I am using Access database. Now i compact the database by using DAO and sometimes using JRO. But to this both, we have add the COM reference.
View 2 RepliesI have the following code which I hoped added a row to my DataGridView and also a record to my database. It does the first part, but not the second.
Dim row As DataRow = Me.CCLogDataSet.tblLog.NewRow()
row("cc_log_contract") = Me.txt_Log_Add_Contract.Text
row("cc_log_registration") = Me.mtb_Log_Add_Registration.Text.ToUpper()
row("cc_log_milage") = Me.txt_Log_Add_Milage.Text
[Code] .....
It seems to be storing the data in memory? As the data in the DataGridView is persistant, even after a Relaunch of the application. However, why I query the database, there are no records in it.
I'm updating an old VS 2003 project to VS 2010. Part of the application uses the old JRO COM object to compact the database. That seems to be depreciated in 2010.

View 2 RepliesI'm wanting to add an SQL Compact database to a VB project. I am running VB 2008 Express and using SQL Compact 3.5 SP1.I've followed the various tutorials in adding an SQL compact database in VB but in all cases when I add a new item to the database (from within my VB Form1 window), pressing the Save button (via Binding Navigator Toolbar automatically added to Form 1) will save the data to the defined 'DataSet' BUT will not update the main SQL compact database.I've followed the tutorials line by line many times now.Anyone have an ideas why this will not function - the tutorials say it should be automatic?

View 3 RepliesMy VB.NET program compacts and repairs my DB, but somewhere in the process unsets the database password. No problem, just reset it through VB, right? not sure how to go about that task.
So I either need to know how to compact it without losing the password, or how to reset the password after I lose it. Trying the best I can to make the code look decent in my post, let me know if there is a better way.
Dim strAccessDatabasePath As String = System.AppDomain.CurrentDomain.BaseDirectory & "App_DataSquirrel.accdb"

Dim TempFolder As String = System.AppDomain.CurrentDomain.BaseDirectory & "App_Data emp"
Dim TempDB As String = TempFolder & " emp.accdb"

I have a form with a textbox to enter a number and a button called "Create". When a user enters a number and clicks create the form gets populated with the number of buttons entered in the textbox and the title of the buttons are labeled by consecutive numbers. For example if you enter 5 the form will populate with 5 buttons labeled button1, button2, ...button5. When you click on these newly created buttons a messagebox will popup stating the buttons name. Basically I need to know how to create events and populate them with code I guess dynamically.

I want to monitor more than 10 folders on different machines by using SysTemFileWatcher. I create a class called Watcher for doing monitoring. So, for each folder I have to call that class once with a new thread. I want to name each thread with its own name like: T1, T2, T3 ... for easier controlling them. It is not nice if I declare each thread like:
Dim T1 as Thread =new Thread(Address of Watcher.StartWatcher)
Dim T2 as Thread =new Thread(Address of Watcher.StartWatcher)
...
Dim T18 as Thread =new Thread(Address of Watcher.StartWatcher)
How can I declare thread names dynamically with the names just like that. I have tried to use Thread array() but it doesn't work.
