the access data are not getting reflected on the DataGridView unless the form is reloaded again. I am acessing the MSAcess data for back end processing (SELECT,DELETE)using odbc connection and displayin on .NET form using DataGridVew
View 2 RepliesIn datagridview,i want to display the amount without decimals. so whatever values coming from backend,i'm directly assigning to cells value.then in cell formatting event, i'm formatting values without decimals,so here after formatting,the formatted Cell Value not reflecting in Original value. when i read the formatted value , its displaying only assigned value not formatted value..ex :
Public Class Form1
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
DataGridView1.Item(0, 0).Value = Val(12.123)[code].......
I am developing an application on VB2008 with MySql as database. I opened the connection without any errors. I have three fields/columns in my database and on the form. When I am running vb form data is not reflecting on to form fields.
I have written the following code in form load event.
'Dim cn As ADODB.Connection
'Dim rs As New ADODB.Recordset
'cn = New ADODB.Connection
'cn.ConnectionString = "DRIVER={MySQL ODBC 3.51 Driver};" + "SERVER=localhost;" + "DATABASE=in_out;" + "UID=root;" + "PASSWORD=pacvision;" + "OPTION=3;"
'cn.Open()
'MessageBox.Show("Connection Opened Successfully")
'rs.Open("Select * from deptno", cn.ConnectionString, ADODB.CursorTypeEnum.adOpenKeyset, ADODB.LockTypeEnum.adLockOptimistic)
I have a table in Access called 'tblRealTime' with a few rows of data and I want to display it in a DataGridView object on my form. When I run the program I get no errors but nothing shows up in the datagrid. My code is below:

ConnString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|K0201227Project.accdb;Persist Security Info=False;"
SQLStr = "SELECT * FROM tblRealTime"

I have a table I made in MS Access and I want to import/display that table into a DataGridView.I am VERY amateur but I am able to pick apart some code and see what is happening.The thing I know I need is a connection between the two programs but again, have no idea about how to pull it off.I have the free version of VB(2008 Express Edition)

I'm trying to remember how to insert data in to a table. Here is my code
Code:
I get the error
Quote:
Number of query values and destination fields are not the same.
I also get some error about the Insert INTO part not being right somewhere. Am I doing this how you would do it, or how would you do something like this?
Using Access I created a few Data Access Pages. These web pages, once opened, work fine to manipulate data as intended, but they keep generating annoying warning messages.There are two messages that pop up every time the web page is accessed. Before the page opens the first message that pops up states: "This website uses a data provider that may be unsafe. If you trust the website, click OK, otherwise click cancel."After pressing OK on the first, the second message pops up and states:"This website is using your identity to access a data source. If you trust the website, click OK, otherwise click cancel."After pressing OK on both messages the page functionality works just fine.I've tried adding password protection to the database and even signing the project with a digital certificate, but I still get the warning messages. This would be fine except there are multiple end users for the access pages and I am trying to avoid the additional confusion this will create, especially since IT has restricted many of the users from editing the internet options.

I'm using XP and access 2003 and visual studio 2005. I created a project and connect this project with database access file. and I created some textboxes and command button on the form. Is possible to modify and add a new record to the database without using the navigation toolbar by insert a code in the command button.
View 1 RepliesI am new convert from VB6 and needs some help developing a stand alone application in VB 2008 that needs access to stored data values.All applications I have developed so far have been for computers that have either SQL Express or Access installed locally on the computer. This has made development really easy since I could use ADO to access and query the data.
The application I am now developing will be installed on a computer that does not have any of the MS office applications and I do not want to install SQL Express on the computer. But I still would like to use an 'ADO type' functionality to access, query and modify the data stored in the system.I started looking into using XML, but I was unable to find much information on querying and modifying individual elements.
How do I put a large amount of data (we are talking of a datatable with probably 50 columns and maybe 500 rows) from the access database that is bound to a datagridview in my program into textboxes depending on the row of the datagridview row I am clicking on.
What I have in the access database is countries and companies that are attached to several different dates to each company. these dates are supposed to be filled into the textboxes automatically when I click on the company row in the datagridview and also when i fill in a date in the textboxes it is to be written to the access database when I save the update.
I have used the below load code to fill my datagridview. Is there another way or can I use this?
Private Sub MainForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.TCOMHRVT2TableAdapter.Fill(Me.TCOMHRVT2DataSet.TCOMHRVT2)
End Sub
The DataGridView Control only accepts one data source, but there are ways to brake through, ways that I'm not able to find.
View 2 RepliesI have a problem with transfering data from MSSQL Server 2005 to Access.
I need to make a VBScript that can take out all data from one table in mssql and update one table in Access. The tables exist in both databases and looks the same, but there can be more data in the table from MSSQL Server so i need to update the table in Access with this data.
E.g. I have a table called: SMP_Alert in both database's. So i want to do something like this (dunno if that is possiable):
Set objConMSSQL = CreateObject("ADODB.Connection")
conMSSQL = "Provider=SQLNCLI;Server=127.0.0.1SMP;Database=SMP;Uid=SA; Pwd=smp;"
objConMSSQL.Open(conMSSQL)
[Code].....
Or do i need to create a recordset of the table (SMP_Alert) from MSSQL, and loop through it to transfer the data into the table in the Access database?
i am working on my first database program. i believe that I am almost finished, except that i have a remove button like i would like to remove just a single selected row both from the datagridview and the actual database. this is just in case any information is entered wrong, and also to delete all the entries i put in just for testing purposes. the only problem im having is in updating the database after removing the row from the datagridview

I use Visual Studio 8 and Sql server for my database. I have a form with a DataGridView where my records are display on from the database and some text boxes. I want to pass the data from a specific record from the DataGridView to the text boxes whithin the RowHeaderMouseDoubleClick function.
View 3 RepliesI am quite green to VB .NET and it start occuring to me that I am doing things probably in a very ineffective way.Anyway here is the problem I have datasets, consisting of integers there is set 1 which is of format ID, ID2 - ID here is unique but different ID can refer to same ID2. Before I start reading in the data I have unknown number of these entries (ID and ID2 can be at least as high as 99999999)
Then I have a second data set of format ID2 here is the same as in the set 1 and it can contain several PID entries (all integers). In this set the ID2 is unique and again for one ID2 there can be unknown amount of these PIDs, same PID can occur more than once.

Source: DataTable
Destination: Access Database Table
I should mention that the DataTable contains data resulted by an SQL SELECT query and it's not related to the "targeted" Access Database Table.
I have an Access database that is updated directly in Access. I'm trying to write a program to 'monitor' the database, and have a DataGridView control showing the contents. When the program is first started, it shows the current data in the DB fine, however, I've been unable to get it to refresh with any updated data from the mdb file. I have a timer running on 5 second intervals, and if i clear the dataset, the DataGridView refreshes to empty.

I'm presently creating an application which uses Access2007 as the database. No problem there. But Since most use Excel for data-entry, i've created two tables in access linked to excel source file. Any change in excel will reflect in Access database and subsequently in my Application . Until now my application only reads the database and displays records in DataGridView. These records, i then export to excel along with other formatting for direct printing as a report as I have no idea how to make report. Now i want to add data-entry capability to my app using password-protection user-access. So i can directly add new record to source file. Also need to know if There's any way of eliminating Access from the picture entirely....
View 1 RepliesI am creating a reporting app that pulls information off of a Sql database and populates the data in a datagridview control (DVG). I am using tab pages (Tabcontrol), and I have about 10 tabs with within the control. What I have done is created a dynamic control that will populate in each tab page once the tab is selected. I am using a split container and in my split container.panel 1 is where all my buttons and search functionality will be. In my split container.panel2 to is where the main DGV control will be. I have got this to function properly, however now I am unable to add anything to my split container.panel1. I would like to add diffrent labels and buttons in the panel1 one without putting another panel on top of the split container.panel1, and also if i do this when I resize my container the panel will just sit there. I am using the selected index changed event to get my split container to show in each of the diffrent tabs
Private Sub searchTab_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles searchTab.SelectedIndexChanged
searchTab.TabPages(searchTab.TabPages.IndexOf(searchTab.SelectedTab)).Controls.Add(splitContainer1)

i've been experimenting on some WebBrowser stuff on Visual Basic 2010, and after experiencing a lot of things, i still wonder how can i add multiple header modifiers, for instance i've added a mod to the Referer (yes with one r) which actually mods the site's referrer and stuff like that,
I want to know how to change other refs for the same site like user-agent and things like that. but all together for the same site,
This is the code
Quote:
Dim HEADERS As String = "Referer:http://www.google.com/search?q=" + TextBox2.Text + "&oq=" + TextBox2.Text + "&aq=f" + Microsoft.VisualBasic.ControlChars.CrLf
Dim URL As String = TextBox1.Text
WebBrowser1.Navigate(URL, "_self", Nothing, HEADERS)
How am i supposed to add the user-agent change thing, for example next to the referer or something like that. do i need to create a new dim? how is it supposed to look like?
I have (between others) 2 projects in my solution: one WinForm project, that defines a Form (say, MyFormProject), and other a UserControl (MyControlProject).When I modify MyControlProject's code and launch the debug, I see that any modification is not taken into consideration. I need to clear the solution, rebuild, for make it work...
Additional info: I use in the UserControl the Dbi-Tech Components. Also, in the WinForm I use Infragistics components. Are both license files compatible, cause seems that both should user licenses.licx file?When I wrote a new method in the Control, I got a MissingMethod exception in runtime, however, the code compiled without any error.Then I removed the references, re-added them, and the exception in runtime didn't appear.
