View 1 Repliesi have a webproject to work on and it requires quite a few applications, windows explorers, etc. to work on..
what i was wondering is, if i can open my applications, like shelling them, but in a tab control, so when i start my app, it has firefox loaded in tabpage1, notepad ++ in tabpage2, graphics program in 3, and so on.that way they're always in a set order, which is sometimes hard to do with the taskbar.
I have created at form with a tabcontrol. On tabpage 1 and tabpage 2 there are a textbox, each containing a setting. When the form loads only the setting on tabpage1 is loaded. Tabpage2 remains empty. What am I doing wrong? Does form_load not work with a tabcontrol?
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
My.Settings.textbox1 = TextBox1.Text

I have 1 tabcontrol with 2 tabpages, 2 different datagridviews (2 tables)on each tabpage.
Tabpage1 is Always ok. On the tabpage2, I did several delete records and went back to do the add record, WHEN I did the second add, the cursor won't move on the textbox, I COULDN'T DO THE ADD ANY MORE. Why?(this is on the 2008 vb express)[code]...
I'm attempting to create and populate a table in a new Microsoft Access (Jet) database using VB.Net 2008 Express under Windows XP Pro SP3. The database and table are being created properly, but loading the table proceeds VERY slowly. When I am loading the table, no complicating factors that might impact performance, such as indexes or table relationships have been defined. The table to be loaded is made up of relatively short rows consisting of three single byte columns, and one (four byte) integer column. I am loading approximately 16 million rows, and this is literally taking hours, while the same data can be interactively imported into Microsoft Access from a .csv file in minutes. I am trying to batch load the rows, 64K rows at a time, in order to avoid the overhead of individually transacting/committing each row individually, but suspect that I must not be doing something right. Key code that I am using for this process is provided below.

I must have inadvertly messed up my data connection but not sure how to fix it. when I check the table adapters I can view data but when I load the app I get these errors and no data loads, how can I look at this log and make sense of how to fix this?

I build my project and i got some problems. First i want to print barcode for books(toolstripmenu item). but i cant. here's the code that i found:
[code..]
second problem is printing again. i want to print my MS ACCESS .mdb from child datagridview's records.
third one i want to save and load(with dialogs) my database from main form to child forms' datagridview.and the last one is help provider. i prepare my own .htm help file, when press F1 it opens. but i dont know how to call provider to toolstripmenuitem and help provider keep my computer's path so when i call provider another computer, the programme cant find the path.
I have a user control which consists of a dataviewgrid with some extra panels controls etc.I have just updated this program from an old version of vb where the tab control was just a row of tabs with no actual child pages attached.so to use several of these userControls (called 'Pages' from now on) a Panel was created and placed underneath the tabs to give the illusion of tabpages.when a user clicked a tab the relevant 'Page' was brought to the top of the Z order. This was accomplished with a directory of the 'Pages'..This all worked fine until I decided to change to using the TabControl in VS 2010.
So I didn't need the Panel anymore I just added the 'Pages' to the TabPages instead and I could also get rid of the directory to access the pages as it is not needed for display purposes anymore and for other access I could use the Tabcontrol.TabPages collection instead.Now when each 'page' is created and setup the dataviewgrid is loaded with a Table and the columns are re-ordered.I am loading approx 20 'pages' to the tabcontrol 1 to each newly created tabpage obviously. this is done using using a for each loop from a DB table.now the problem is that the first 'page' dataview grid has the columns re-ordered but none of the others do ! the Data is fine it's just the column order that's wrong.the same code is used for all (The setup is method of the 'Page') and i have stepped through the code and it all works OK with no exceptions. no code is missed but the grid order is OK for the first 'page' but not the others.everything else works fine the 'Pages' are all on the TabPages and the data is OK..Now comes the really weird bit! if I add the 'page' to the old unused panel before i add it to the Tabpage all the grids are re-ordered fine as in [code] Now the Panel is visible but not on screen if you see what i mean obviously if i move it on screen it's empty as the 'page' control can only be in one place and it's on the Tabcontrol..so why is it working ONLY when I add it first to the unused Panel? what is happening here? Oh BTW it only works for this Panel - not if i create a new one and add it to that..AND if the Panel Visible property is set to false the columns are not re-ordered again? I have tried deleting the panel and all code that uses it but the grids are not ordered properly till i re-instate the panel?
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:
Public Class MainForm
Private Sub EvalPage1BindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles EvalPage1BindingNavigatorSaveItem.Click

I'm using VS 2010, and I did a project using VB and a database in Access. The problem is that when I try to put that "application" on other computers, sometimes, is not working. I thought it can be because on these computers they don't have access, but on one computer, is running another app which is using Access and there is no Access installed. How can I check if my application requires Access to be installed or not?
Here is a example of how I did the connection:
Public AccessOLEDBConnString= "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & myfullpath & ";Jet OLEDB:Database Password=password"
Function getConnection() As OleDb.OleDbConnection

what do you think would be the best way to load a fixed length text file into ms access? this is how i would normally do it if it was comma delimitted:
