View 1 RepliesI want to create a textbox which contents are validated every time the text in it changes. And an image is displayed beside the textbox if it is correct and another image shows up if its not correct. Pretty much like ajax.
Heres the method which I called from the class.
Public Sub read1()
cmd.CommandText = "SELECT * FROM testdb WHERE Name='" & name & "'"
Try
[Code]....
Problem is, the method seems to be only called once. And the first image that was displayed stays the same even after inputting a data which does not exist in the database. I'm connecting this program to a mysql database using odbc.

View 4 RepliesI am trying to pass a variable or find someway of displaying data in a datagrid that is based on a textbox.text field in a form.
I have a form that holds Customer details. I want to show relating data in a datgrid on the same form that will vary depending on what customer is selected.
This VS2008 Windows form.
In my form.load event, there is a bindingsource.fill event.After the .fill, there are two or three other lines of code that query the newly filled tablemanager. The code gets the number of total records and displays that number on the form.Here is the problem ....When the .fill statement is executed, control reverts to the form and any statement AFTER the .fill event is not executed.I have tried to stick the remaining lines of code into some other form event with little success. These three lines of code only need to run once.Does anyone have a suggestion as to where to stick these lines?

I was wondering if there is a way to change the Fill command text of a datatable before issuing it.I need this because the table I am opening has over 15 thousand rows and it hangs for a while in the network when filling the table. So I would like to tell it what to SELECT instead of getting the whole table and then applying a filter.If there's a way of doing that without changing the fill command, it will also work for me.

How do I input the cell details from my datagridview column to my login form and submit access to the member page?
I am using VB 2008 Express to connect to an Access 2007 database. I have a combo box that is populated by the database. When I used the Access report VBA, I used the AfterUpdate() event to calculate a sum and place the results in a text box. I need to know how to do the same operation in VB 2008 Express using the SelectedIndexChanged event of the combo box.
The combo box is called "cboYearMonth" and is populated by my database, this is working correctly.
The text box that I want the calculated results to appear in is called "ExactPagesTextbox"
I have a query in Access called "JobTypeExact_Query" that contains all the pages that I need. What I need to do is calculate the total number of "Pages" limited to the YEARMONTH selected in the combo box. YEARMONTH is a value in every record in this query.
For some sort of reason, which I can't seem to spot, this fails and I get a #Name? error. When I tried to do this, I use pretty much the same code in another place in my form; the only difference is the "cbo" and the names of my txt and alike.
[code]...
Can anyone spot my error? What I wish the code would do is when I Select something in my cboVarenummer, the TextBox txtVarenavn changes its text to what the sql statement returns.
For my project i want to i want to export form data to a new database so that i can send it by attaching it to email.
what i want that on click of a button
1) create .mdb file at c:est*.mdb, with the name = "textbox1.text"
2) create table, name = "demo" with column "id" and "job No"
and then i can use insert command to fill the data in the table and email it to client.
I am trying to write codes for new user to fill in the form, then the new data will add into my database.
Below are my codes:
Imports System.Data.OleDb
Public Class NewUser
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
End Sub
[Code] .....
There is no error encountered, however, the adding is failed and no new data can be add in.
how do i change the label text when I select one item from the combobox.
E.g my combobox contain : A, B, and C
When i click "C" from my combobox, my text label will also change to "C"
When the form loads I want to fill the combobox with the data present in the database. So I did the below
Private Sub BindCombo()
con = New OleDbConnection("Provider=Microsoft.Jet.Oledb.4.0;Data Source=C:UsersGautamDocumentsVisual Studio 2005ProjectsF1pracF1pracBank_Account.mdb")
con.Open()
cmd = New OleDbCommand("Select * from BankAccount", con)
[Code] .....
Doing this code the data is added up in the combobox dropdown list. But when I am selecting a data from the combobox dropdown list,the all the corresponding data of the other combobox also get filled automatically. I don't want to let the other combobox filled with their data automatically....
I have successfully navigated to the page I want and now I need to know how to fill in text boxes on the page. I used SendKeys.Send before but that was when the first box was already selected. I can't seem to get the box selected by tabbing at all. I can find the textbox id if that helps.
View 4 RepliesI got a Sub which processes a code, and then it does whatever the code said. Example.
Code = "Black" -> Turns screen black.
Code = "OFF" -> Turns off the PC.
And so on.
If I call that Sub from Immediate console, It works perfectly. But if that Sub is called from an event, It does nothing, and usually throws an Exception. I read somewhere that I can fix this by using Threads, but I don't understand how that can help and make it work.

I have a form with over 100 textboxes that are set in multiple groupboxes and that number grows as I continue working. I am trying to get an event to fire if there is a keydown on any one of the textboxes. other than individually adding all 100 textboxes to the handler, is there a way for me to create a single event that handles all textbox.keydown events on the form?
I want to run something like the code below every time a textbox on my form changes. The code rules out text boxes within groupboxes that I don't want to fire.
If TypeName(SplitContainer1.ActiveControl) = "TextBox" and InStr(ctrl.Parent.Name, "GroupP1Payoffs") = 0 _
and InStr(ctrl.Parent.Name, "GroupP2Payoffs") = 0 and InStr(ctrl.Parent.Name, "GroupP1LoanDetails") = 0 Then
