Calling Properties Of Form1 Into Another Form (loginform)?
Dec 1, 2009
I have 2 forms, main Form1 and a loginform. When I start the application, first "Form1" is loaded and then with a button click, user can load "loginform" if required to enable/disable some features/controls on Form1.The sequence is like this:
1) Load main form Form1
2) click a button on Form1
3) Load the loginform.
4) enter user/pwd and click OK button
5) enable/disable "GroupBox" control on Form1 if login sucessful.
For this,I made a click event for OK button in loginform, so once user clicks the OK button, I want to call one function which is defined in Form1 as a Public, which enables/disables the "GroupBox" control on Form1. The code structure is like this:in main Form1, i created a function like this:
Class Form1()
Public Function DoThis() ' Function to enable/disable GroupBox control
....some task...
[code]....
I am not able to call the DoThis() function in loginform. Please suggest me with a piece of code how to do this?? remember that Form1 is my main form which is loading first.

I need to be able to start with Form1, move to LoginForm, then back to Form1 taking 2 variables and the "values" they have in the LoginForm back to Form1 and using the variables. I start with the main form (Form1) and have the user enter some information. Once they click OK I have the LoginForm open. After they enter their credentials I will check to make sure they are legal users, then go back to Form1 (here is where I need to take the Username and Password with me) to log onto a server using the same credentails from the login form.

I have an exceptionhandler function that basically just writes a line to a textbox on Form1. This works fine when being run normally but the second I use a thread to start a process it cannot access the property. No exception is thrown but no text is written to the textbox:
Public Sub ExceptionHandler(ByVal Description As String, Optional ByVal Message As String = Nothing)
' Add Error To Textbox
If Message = Nothing Then
Form1.txtErrLog.Text += Description & vbCrLf
Log_Error(Description)
[Code] .....
Is it possible to access a form's properties from a thread this way or would it be easier to write to a text file or similar and refresh the textbox properties every 10 seconds or so (Don't see this as a good option but if it's the only way it will have to do!).

I'm trying to elaberate on some basic examples of .Net programming in using VB. The basic example of creating a new instance of Form1 is:
Dim x as New Form1
x.Show
I've added some OptionButtons to set the StartPosition of the Next Instance of Form1 as well as some Labels that display the Top, Left, Width and Height properties when the new instance of Form1 is Shown.
This is the code I'm using.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim x As New Form1
If Me.RadioButton1.Checked = True Then
x.Top = 0
x.Left = 0
[Code] ......

I'm trying to call the windows properties page of a selected network card from a combobox, so it shows the current settings of the selected networkcard. I mean, like if someone would go to the network settings - right click on the appropriate connection, and go to the properties. For a file properties, one can call the properties by using the shellexecuteinfo function.

Using VB 2008:Situation: A Form1.BackgroundWorker calls a Form1.subroutine. That sub starts a Form1.Timer with Me.tmrOK_BlinkForm.Enabled = True...fires Timer code in event: Public Shared Sub tmrOK_BlinkForm_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles tmrOK_BlinkForm.Tick
Form3.Visible = True
Form3.Label1.Text = gNowButtonDispText
Form3.BackColor = Color.White
Form3.Refresh()
[Code]...
There must be a way to do this, I just need the correct BackgroundWorker Syntax send Stop commad to Form1.Timer from Form3.Click_event...all inside a Form1.BackgroundWorker thread started in Form1.

Currently, I have a LoginForm that authenticates a user and it works fine. I have a MainForm, which is displayed if a valid username and password is entered. I have done this by using the following code in my LoginForm:Private Sub OK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles
[Code]...
Now this does exactly what I want except I fear it's a work around and it's not the best approach. Also, note that I am using Me.Hide() to hide the LoginForm, is there a way to show the MainForm and then close the LoginForm instead of hiding it? Doesn't Me.Hide() call creates an overhead?

Picked up a legacy VB.NET project originally written for version 1.1 of the .NET framework. I'm running Vista with .NET 3.5. I have cleared out all the original error and the project will build; it just wont run.
As far as I can tell, it is trying to run 'LoginForm' but putting breakpoints in doesn't work because the error is thrown before the breakpoints are reached, regardless of where in the file they are placed.

The following code does create a form within a form and does place NotePad inside the child form. You have to manually start NotePad prior to execution (I work on that later) but the code does workŠ My problem is now I want to manipulate the properties of notepad i.e. focus, size, location, etc. but I cannot figure out how to reference notepad and its properties.

All I want is to update the selected row data in form1 to another form2
Form1 Objects
Form1 = MainAppForm
DataGridView = DGVMain <= binded
Button = btnUpdate
Form2 Objects
Form2 = frmUpdate
Button = btnSubmit
15 textBoxes = you can see its name in the code below and all of them are data binded
MainAppForm Code
Pass the selectedrow data to form2 (frmUpdate)
Private Sub btnUpdateDouble_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUpdate.Click
If DGVMain.SelectedRows.Count = 1 Then
Try
frmUpdate.ItemIDTextBox.Text = DGVMain.CurrentRow.Cells(0).Value.ToString()
frmUpdate.PartTypeTextBox.Text = DGVMain.CurrentRow.Cells(1).Value.ToString()
frmUpdate.PartNameValueTextBox.Text = DGVMain.CurrentRow.Cells(2).Value.ToString()
frmUpdate.PackageTypeTextBox.Text = DGVMain.CurrentRow.Cells(3).Value.ToString()
frmUpdate.QuantityTextBox.Text = DGVMain.CurrentRow.Cells(4).Value.ToString()
frmUpdate.UnitTextBox.Text = DGVMain.CurrentRow.Cells(5).Value.ToString()
frmUpdate.DescriptionTextBox.Text = DGVMain.CurrentRow.Cells(6).Value.ToString()
frmUpdate.LocationTextBox.Text = DGVMain.CurrentRow.Cells(7).Value.ToString()
frmUpdate.ProjectBoardTextBox.Text = DGVMain.CurrentRow.Cells(8).Value.ToString()
frmUpdate.CommentsTextBox.Text = DGVMain.CurrentRow.Cells(9).Value.ToString()
frmUpdate.OrderCodeTextBox.Text = DGVMain.CurrentRow.Cells(10).Value.ToString()
frmUpdate.CurrencyTextBox.Text = DGVMain.CurrentRow.Cells(11).Value.ToString()
frmUpdate.UnitPriceTextBox.Text = DGVMain.CurrentRow.Cells(12).Value.ToString()
frmUpdate.SupplierTextBox.Text = DGVMain.CurrentRow.Cells(13).Value.ToString()
frmUpdate.ManufacturerTextBox.Text = DGVMain.CurrentRow.Cells(14).Value.ToString()
frmUpdate.Show()
Catch ex As Exception
System.Windows.Forms.MessageBox.Show(ex.Message)
End Try
ElseIf DGVMain.SelectedRows.Count = 0 Then
MsgBox("Please select one item to update!", MsgBoxStyle.Information, "Update")
Else
MsgBox("Updating multiple Items is not allowed!", MsgBoxStyle.Information, "Update")
End If
End Sub
Form2 Code
I want to update the data by this code, but it refresh only the data in Form1
Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
Me.Validate()
Me.SparePartsBindingSource.EndEdit()
Me.SparePartsTableAdapter.Update(Me.InventoryDBDataSet.SpareParts)
'Refresh
MainAppForm.SparePartsTableAdapter.Fill(MainAppForm.InventoryDBDataSet.SpareParts)
End Sub
No problem in updating the data if I put the code below in Form2 load event
Me.SparePartsTableAdapter.Fill(InventoryDBDataSet.SpareParts)
but the problem is, it will refresh all the data in the Form2, and my code in Form1 becomes useless.
Thanks in advance!
