Textboxes Not Displaying Correct Record Values?

Nov 29, 2011

I got 100+ textboxes that display record values. Most of the textboxes display correct values but several textboxes doesn't. These are the same textboxes. And they only display wrong values if I edit a record for the first time. After correcting the wrong values in the textboxes the first time, they display correct values in succeeding editing of records. Tried to compare their properties and all but they are the same with textboxes that worked...

Private Sub english_proficiency_answersheet_Form_Activated(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Activated
Me.Text = "EPT Answer Sheet of " & gsLastName & ", " & gsFirstName & " " & gsMiddleName

Datagridview Bound To Bindingsource: Displaying Both Old Values And The New Values

Mar 23, 2011

I bound datagridview to bindingsource. The bindingsource has its datasource a collection Called Rates which is a collection of Rate items. The rate object has a property called VALUE. I need the user to be able to edit different values for the collection; However, on the datagridview, i need to keep displaying on one column called OldValue the existing Rate value before the change while allowing the user to edit that value in a second column called NewValue.

In other terms, One colum OldValue will keep the existing values from the DB before being edited by the user, this column OldValue is readonly. Another column NewValue will display, the 1st time, the old value from the DB (similar to OldValue when we do the Fetch from the DB), but it`s editable column, so the user can modify each value in the column NewValue without overriding OldValue cells. For now, I bound both columns OldValue and NewValue to the same property VALUE of the Rate object,

Displaying Data In Textboxes Based On?

Nov 5, 2011

I'm not quite sure where to begin with this. This is basically how I'm trying to get it to work. I will enter the ID of a Hire Record in a textbox, hit the show hire record at which point it will materialise that hire records details in their associated textbox fields.I attached a screenshot of the form in question. I can also create a new record as you may be able to see by typing in the details and hitting create record (this is not a problem, i already understand how to do this), but I also want to be able to display an existing records details in the textboxes again

DB/Reporting :: Adding New Record On Form Load - Show Correct Row ID

May 5, 2008

In an attempt to learn VB I'm trying to build a database project for a friend's business. This db will be used to track customer information, predominantly for targeted marketing purposes. So far, the development has been slow (I'm still trying to adapt from VBA to VB), but its all starting to make sense now. I'm using two different forms for adding new customers and reviewing the information of existing customers, mainly because the database will grow by about 2,500 customers per year and we wanted to be able to search the records without returning every record when the forms load. Most of this works so far, but I'm having trouble with two issues.

When I open the new customer entry form, I want the form to automatically begin entering data without clicking the "Add New" button. The second problem involves the row ID from the database. It keep showing up as "-1", "-2" etc. The row ID records properly in the table, so no big deal. I have read that this problem is a bug in VB and that its nothing to worry about. However, down the road I will need to access the correct row ID from this same form in order to print out a report for the customer (as needed).

For what its worth here is the code I have so far:
Code:
'Update current record when the form closes
Private Sub frmNewCustomer_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
Me.TblCustomersBindingSource.EndEdit()
Me.TblCustomersTableAdapter.Update(Me.dsNewCustomer.tblCustomers)

Multithreading - Single WinForm Displaying Two TextBoxes

Jun 15, 2010

Here's the setup: I've created a class that represents a temperature and humidity monitor. This class handles all of its own operations (connects to the monitors via TCP, reads the temperature and humidity values at set intervals, logs the data, sends email notifications, etc.). I've got a single Windows form that has two textboxes for displaying the values of temp and humidity. When I start the application, I simply instantiate an object of this class and let it do its thing. Every five minutes, it opens up a socket connection, pulls in the data I want, sets the Temp and Humidity properties of the object to the values it obtained, and fires a DataUpdate event which is captured in an event handler in the Windows form.

When this event occurs, the textboxes on the form are updated with the values from the Temp and Humidity properties of the object. Works like a champ. However, I've been playing around with multithreading. Since a disconnected device will cause my entire application to block when it tries to connect, I decided to place the socket connection/data acquisition method into a separate thread. If it can't find the device, no big deal -- at least it doesn't lock up my UI. This thread is instantiated and started inside the object code, NOT the Windows form.

Here's my question, the socket connection/data acquisition method is run inside this new thread and sets the properties of the object when it's done. So, why do I get an illegal cross-thread exception on my Windows form, now, when I try to update the textboxes? It seems to me that the instance of the monitor class is running in the same thread as the Windows form. I only employ a separate thread when I want to run the socket connection/data acquisition method. Is my understanding flawed? I can display the updated property values in message boxes that are called from the Windows form. I just can't manipulate the textboxes.

How To Set Some Of Correct Values

Apr 17, 2012

My VB code uses a timer with a slider, and uses AddSeconds. I am trying to use the slider with a min value of 0 and max value of 600, and set up ticks every 30 seconds between 0 and 600.At a beginner level coding VB,I am not sure how to set some of the correct values in the slider's property box.Min, Max and Value, I am guessing are 0, 600 and 0 (sets the slider thumb starting positionat the far left). But I am not sure what other values, like tick and small and large change, etc. need to be set and set to what value? I've read online, but so far cannot find how to configure this.
