Auto-refresh Windows Form - Sub Form With A Datagridview ?
Apr 16, 2009I am working on VB.Net. I have a sub form with a datagridview, that is being loaded with the criteria taken from another form. Hence this form is called with parameters.
Here is the code that calls the sub form.
Code:
where ds is the dataset to fill the datagridview and rb is the string from a radio button on this form.
Here is the code in the sub form.
Code:
Now, I need to refresh this sub form every -- minutes, depending on how the user wants it to be. For this I have given a NumericUpDown control to select the mins. All this works fine. But how do I refresh the dataset and the datagridview?
Form Don't Auto Refresh When Change Certain Values
Dec 23, 2010i am currently making a project which is to make a cinema screen booking system. My main problem is that although i have most of what is working i need to find a formula to give the full result (overall price) in a label. My other problem is the fact that when i interact with my form certain things dont auto refresh when i change certain values e.g i change number of seats but it doesn't auto refresh the price or anything OR i click one discount then another but nothing changes and it keeps the old value.
Okay in my menu i have a CombBox (ComboBoxScreen) for choosing the film and there are 3 films to choose from in the drop menu each with their own price. I also have a Textbox (NumberSeats) for inputting a number of seats you want to book for chosen film. And lastly there are 3 radio buttons each with different discounts. e.g No discount, 10% off and 25% off. A formula to work out the overall price uses all three functions/tools above. [Code]

View 9 Replies.net - WebBrowser Control Auto-refresh?
Oct 8, 2009I want to make a program in Visual Studio 2008 in Visual Basic. It involves a web browser and I want to make it auto refresh and allow people to choose the time period in which they want to auto refresh. It won't take user input but I have checkboxes that are preset. I think this may be possible using a timer and the WebBrowser1.Refresh() method. If I am mistaken, please correct me and tell me how to do this.

View 6 RepliesC# - DataGridView WinForms Auto Reload/Update/Refresh?
Feb 16, 2012I have a windows form with a DataGridView control.I bound it into an attached DB file (.mdf).I perform insertion by generating a dynamic Insert statement. I then pump this sql statement into a SqlCommand object and perform ExecuteNonQuery() method. All of these is performed by handling a Button click event. The button and the gridview is located on the same form.
Public Sub InsertRow(ByVal param1 As String, ByVal param2 As String, ByVal param3 As String)
Dim strConn As String = (the connection string)
Dim sqlConn As New SqlConnection(strConn)
[code]....
After the code execution, the DataGridView is not updating (remains intact). I have to exit the form and reload it to have the updated gridview.For certain reasons, I can't use DataTable object.But I would like to have this gridview updated everytime I run the insertion.

Mar 23, 2010I have an issue that I can't seem to tackle. Going on 3 weeks. I have a VB.NET app with an sqlce 3.5 database. I have created several tables in this database. I have attached them to my form using DataSet then BindingSets and so forth. Done this many time before. VS automatically created a TableAdapterManager for me.I was having an issue getting the Refresh of the primary key value of a newly inserted row. Ok, find out that sqlce does not do big transaction, or multiples rows at a time, found Beth Massi's blog on how to work around this:Ok, got it somewhat to work, but I had to take one of the tables out of the tableadaptermanager so I can update it by itself so insted of doing this:

View 3 RepliesStop Webbrowser Objects From Stealing Focus If Auto-refresh Header Is In Use?
Jul 12, 2010I have a VB.net form which has two webpages embedded. The webpages have a 5 second auto refresh built into the HTML header as the information is constantly changing.
The problem I have is when I pull up a secondary form, I lose focus to the 'Main' form everytime the webpage refreshes.
Is there any way to stop the webpages autorefreshing in the form and I will build in a refresh command into a timer I already have in place and then I can start and stop the refresh at will.
Unfortunatly I cannot amend the source code of the HTML as this is required for a different process elsewhere.
Accessing Datasets Loaded In Main Form From A Child Form?
Aug 11, 2009I have a program I've been working on for some time now and I'd like to try to streamline it somewhat. I have a main menu form that has a split panel, in the left panel is a treeview that displays forms you can open and when one is selected, it opens in a child window in the right panel. Each time I open form I called DWNForm, it does a series of dataset loads which are the populating items for a series of listviews.
What I would like to do is have these datasets load once during the mainMenu load and then have the DWNForm be able to access the datasets once it is called from the treeview selection.

DB/Reporting :: PopUP Form Refresh Combobox On Parent Form
May 31, 2008I have a parent form that has a combobox. Whn the form loads I get the data from the db and bind to the combobox. that works fine and here is the code I use in form load to cause this to happen: [code] Now if there is not an Account Type, I have a button that will pull up a small form to allow the addition of an account type. The popup form adds the data back to the database just fine, but I am now trying to get the combobox to refresh its data. So I call a public Sub that is located in the parent form to from the popup form to accomplish this task and I have walked the code and the sub is called and appears to work correctly, but the new data never appears in the combobox. Here is my public sub that i call to try and refresh the combobox on the parent form. [code] But when I go back to the parent form, the combobox is not updated with the new account. How can i get the combobox to refresh from the database with the new data?

Hiding / Unloading Form When Next One Loaded
Jun 8, 2011I am learning VB.NET and as a first task I am creating a login form. I've been trying to link it to another form once a correct username and password are entered. However, despite that I still cant be able to hide it or unload it once the next form is loaded.
Here is the Code
Private Sub OK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OK.Click
If UsernameTextBox.Text = "chris" And PasswordTextBox.Text = "chrispass" Then
Me.Hide()
Form2.Show()
End If
Me.Close()
End Sub
The Form2 appears as coded above but the 'Me.Hide()' manages to hide the login form but then it appears again.

I'm adding a label, that will tell you if there's anything in your clipboard or not, but the problem with that is that I don't know how to make it check the clipboard all the time.I'm still a beginner, so I only know how to make the app do something when a Form has loaded up, or clicked etc., but how do I make it so it checks the clipboard when it has changed? If I can't do it, how do I make it so it checks the clipboard like maybe every second. Do I need to use threads (I'm not sure, because I don't quite fully understand threads).
