I've started to write an application in Visual Studio 2010 (VB) and I have trouble finding a way to create a button that starts a timer that after 3 sec displays next record of a database (something like slide show). I have a form with 3 textbox (id, field1, field2) and 2 buttons (start and stop).
View 4 RepliesI have a form called studentForm which has a studentCombobox, studentTextbox and a studentDatagridView
In the constructor of the studentForm I need to bind studentCombobox to the StudentbindingSource of the main form and to bind studentDataGridView to appropriate binding source in the mainForm.So that this datagrid view displays all the bookings for the studentID currently selected in studentComboBox
studentComboBox.DataSource = MainForm.StudentBindingSource
studentComboBox.DisplayMember = "StudentID"
studentDataGridView.DataSource = MainForm.StudentDataSet
studentDataGridView.DataMember = "Names "
This is the code I wrote in the constructor
In ASP.NET, what is the definitive way to pull one record from the database and bind it and HTML tag?
View 2 Repliesthis code
Me.vendorLookup.DataSource = vendorBAL_C.vendorTable
Me.vendorLookup.DisplayMember = "SimpleId"
Me.vendorLookup.ValueMember = "VendorId"
Makes the combobox have a list of Names (simpleid) and PK (vendorid)
How do you make the combobox also be bound to a specific row of a record in an "case management" table? I've already used the datasource for a table of vendors - right?Or is this where I put two tables into a DATASET and make that be the DATASOURCE?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim asm As String
asm = ComboBox2.Text
cmdOLEDB.CommandText = "SELECT * FROM sale "
cmdOLEDB.Connection = cnnOLEDB
Dim ab = DateTime.Now.ToString("MM/dd/yyyy HH:mm:ss")
Dim dr = cmdOLEDB.ExecuteReader

I choose one record from combo box... that is bind from name after that when i select another it gives error
I have a timer in vb.net and it's interval is 1000ms ,. i have placed in it's timer_tick event a code that will print screen the screen and save it to a database.The problem is when i click outside of the form, or loosing the focus of the mouse to the form containing that timer/printscreen, the timer stops. As a result the printscreen also stops.here are it's properties:
generate member = true
interval = 1000
modifiers = friend
I have created a project that has an add a new record, edit record and a search form, that has multiple text, combo boxes and is working great.Last nite I have added a checkbox under my add new record form and i am saving the checkbox value to my database, so far so good. I would like to be able to search any record that is mark with a checkbox to show up in my search screen when I do a search: [code] The problem that i am having is that now that I have added the code to my project to search for the checkbox field in the search screen and if I leave everything blank and click on the the search button I get no record found. I expected to see all that data, since I have nothing selected. Now if I click my checkbox, as soon as I click on my search button I see that two records that I have added for my test.

I am leaning VB and have created a basic inventory app for work that consist of 4 tables, CurrentInventory, Surplus, Staff and Category. Each of these tables have a corresponding form. My question is with the CurrentInventory and Surplus form/tables. I want a button on the CurrentInventory Form that when clicked the current record would be transferred to the Surplus table and deleted from the CurrentInventory table.I am assuming that I could somehow use the INSERT command to copy the current record to the surplus table but I am not sure how to accomplish this.

Using VB 2008. We have an app with a third party grid on it works well enough. This is a small utility within a bigger suite, and adding/updating it involves a simple EXE copy. The issue I am trying to address is that not all customers will have the 3rd party controls on their systems, and we want to avoid deploying them if we can.
Can I build the app so that if the controls are present, the app uses them. But if they are not present, I use a simpler control? I picture using a 'launcher' form that tries to load Form2 with 3rd party. if it errors, then just load Form3 with common controls. But can I even get to that point? With missing controls, will the app even load? I understand Late Binding for objects, but this is a control right on the form. Can I late bind a control and add it to form dynamically perhaps?

I am creating AutoSave functionality for an application. Its an mdi application. it needs a seperate form where the user can turn AutoSave onoff and set the interval in minutes for it to execute. The users values for these i plan to saveupdate etrieve into my.settings.
I plan to put a timer on the form that needs to be AutoSaved. If the user turns off the timer from the options form, how would i go about stopping the timer on the form that needs to be saved? Should I change the timer to be "Shared Friend" and access it directly from the options form or what?
