I was using 2 forms, the first one has general data capture and the second one is a calendar form. On Form1 I have mulitple windows controls. A Textb ox and beside a Calendar button. When I click on a Calendar Command button, it should open calendar form and once the user selects the date, the date should be placed in the text box on the form1. Identical to this on Form1 I need multiple textboxes that needs date to be captured.I cannot use a global variable for this as I need to validate mulitple text boxes. To explain this, I have a Transaction Date and Date Received. I need to validate whether Transaction date is prior Date Received or not? I dont want to use several global variables b'coz I might need multiple validations as above. Please help me on this.

I have a Main Module that loads a form. I want to update text on a Label, my code is:
Public mFormSplash As Form = New FormSplash
Sub Main
With mFormSplash[code]....
The code loads the form OK but does not update the Label's text (LabelStatus)I am getting an error Error:
'LabelStatus' is not a member of 'System.Windows.Forms.Form'.
This worked ok on a previous project and I can't work out what is different.

I tried to update the button text on a form from a backgroundworker.do_work event, and it failed, with the usual cross-thread exception message.However, by pure chance, I also tried to update text in a system.windows.form.toolstripstatuslabel also from this backgroundworker.do_work event, and it DOES work. Question: why is this? Is it perhaps because theres some kind of implicit shared behaviour with system.windows.form.toolstripstatuslabel?

I have 3 forms, one frmMain - main form, second is frmUserType- childform, and the last frmCreateUserType. In the main form I have a menu item to open my frmUserType, In this form I have a button to open another form which is my frmCreateUserType, In this form I have a button to add records then update the listview in frmUserType. The problem is the listview will not access with my add button control in frmCreateUserType.

I have a webbrowser and on a form I need it to fill text. The problem is, in order for the submit button to activate, you have to atleast type in 1 letter for it to update and make it send. The problem is when I do document.getElementById("p1").innerHTML= "SSSS" it works but it wont update the submit button to allow me to submit the form. What should I do?

I load a bunch of files into a wpf listview and want to update the content of the listviewitems after loading the files, eg:
1. load the files from a directory into the listview - that's okay
2. Start a background worker and replace the full filename with only the filename and extension on each listviewitem. How could i achieve this using dispatcher or background worker?

I can't find a proper answer on how to update the ListView after I inserted another item. When I add ListView1.Clear() and DatabaseSelect() in Button1 there was nothing to view.
How do I refresh my ListView everytime I insert new items?
Here is the code of filling the ListView:
Function DatabaseSelect()
Try
myDA.SelectCommand = conn.CreateCommand()

I am trying to update a ListView control from 10 background worker progress. It is working well if there is only 1000 list in ListView control. But when the list is big then the update is not working properly. The different value is not updating the appropriate list index. Here is my partial code of worker progress:
Private Sub worker1_ProgressChanged(ByVal sender As Object, ByVal e As System.ComponentModel.ProgressChangedEventArgs) Handles worker1.ProgressChanged

Imagine you expand onto 'Sofas and armchairs' and click 'fabric sofas', it will redirect to next page on click and it will send data '10661' to the next page. Then the listview will updated with reference '10661'. After that click on another link, maybe leather sofas. The listview will re-update table with new reference '10662'

I'm trying to use a BackgroundWorker process to update the status on servers once a Refresh button is hit.add all ListViewItems to an ArrayList and pass that ArrayList to the worker process to update. Once it was done updating, I would clear all items from the ListView, and then refresh the ListView with the new ArrayList with the updated ListViewItems.When I get to this line of code in the RefreshListView function:
'POS_IP_ADDRESS is just a constant I created with the column index in the event I decide to change the layout of the list view columns at a later time
objItem.SubItems(POS_IP_ADDRESS).Text = strIPAddr
I get a InvalidOperationException stating Cross-thread operation not valid: Control lstStatus (my list view object) access from thread other than the thread it was created on.Do the ListViewItem objects have a tie back to the original ListView items when I pass the ListViewItems to the ArrayList? I just want to edit the objects in a buffer and refresh the ListView... does this make sense to do? Why can I not update the item in an ArrayList?
