Label To Show Data Located In Another Form
Apr 25, 2012I am new to VB. I have created some labels/textboxes in my Form1. I use them to do some calculations. Basically, this is my calculation area (in Form1) and then I want some of the results that have been calculated and showed in these texboxes to be shown in labels which are in another form (Form2). So here is what I have done in terms of coding:
Label12.Text = Transactions.ComboBox1.SelectedItem
Label13.Text = Transactions.ComboBox2.SelectedItem
Label14.Text = Transactions.ComboBox3.SelectedItem
Label15.Text = Transactions.TextBox1.Text
Label16.Text = Transactions.TextBox2.Text
These codes are in Form2 and Labels 12-16 are in my form2 as well. My form1 is called Transactions as you can see. Everything looks OK, when i run no errors, also when do the calculations and I go from form1(Transactions) to form2, labels 12-16 show the results from form1 but the problem when I go back to form1 and change the values and go back to form2, the labels 12-16 are not changed. They simply show the old values regarding of the fact that they have been changed in form1. So how can I make form2 to show them correctly, to refresh the form or what?

Get Form Name The DataGridView Is Located On
Jan 15, 2012I have a DataGridView that is embedded in a TabPage of a TabControl and the TabControl is embedded in a SplitterPanel of a SplitContainer and the SplitContainer is embedded in a ToolStripContentPanel of a ToolStripContainer which is on a Form. I want to get the name of the form the DataGridView is on, how do I do this?
Note: Sometimes in my application the DataGridView will not be embedded in any control other than the Form. So I would need this code to work no matter what the DataGridView is embedded in. For example, if I send my DataGridView as an argument to a function how can I get the name of the form the DataGridView is located on?

How To Access Variable Located In Private Sub On Same Form
Jul 25, 2009How to access a variable that is located in a private sub and then display that variable in another private sub located on the same form.
My actual code is:
Public Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click
Dim strFileName As String
strFileName = OpenFD.FileName
OpenFD.InitialDirectory = _
[Code] .....
Obviously, the sub in blue has nothing in it currently and so this is the one I would like to access the variable in. The variable I want to use again is 'FILE_NAME'.

Multiple Forms - Declare And Instantiate Second Form On Program Start - Use Button Simply To Show Form?
Jan 14, 2010I have a program that uses two forms. The program opens to the Main form, and the user can navigate to the other form from the Main form through use of a button. Here's the way I've currently written it: When the Main form loads, it declares and instantiates the other form during the load procedure. When the user presses a button, the second form is displayed by means of the ShowDialog method. On the second form, there is a Return to Main Screen button which closes the second form, bringing the user back to the Main form.
So, here's the structure of the code:
Code:
Public Class frmMainForm
Dim frmSecondForm As New SecondForm
Private Sub btnSecondForm_Click(blah, blah, blah) Handles blah, blah, blah
[CODE]...
Here's my reasoning: Originally, I wrote the code so that a new instance of the second form was created every time the button was pressed. The problem was that whatever data was displayed on the second form, previously, was lost when the user returned to it a second time. Since the user would be switching back and forth between these forms, frequently, I needed that data to persist.
What is the best practice for accomplishing this:
1) Declare and instantiate the second form on program start, as I have done, and use the button simply to show the form?
2) Declare and instantiate the second form each time the button is pressed but maintain the variables on the Main form and pass them ByRef to a custom constructor for the second form? Is this even possible?
3) Something else?

Use A Progressbar To Show On Main Form And Then Finish When Next Form Is Loaded

.net - Open A Form With Form.Show First Mouse Click Is Ignored?
Nov 12, 2009Using the code below:
Private Sub ShowDropDown()
Using f As New DropDownForm
f.Visible = True
Do While f.Visible
Application.DoEvents()
[Code]...
This was a guess, after looking at the Form.ShowDialog method in reflector.My question is, is there a managed call I can make to acheive the same result, and what does a button click do that other clicks don't?
ETA: The problem does not occur if I open the form using a key.
Form.show() Loosing Context In Originating Form?
Nov 8, 2011This is a database app where I am trying to check for possible duplicates and give the user the option to keep the new record or assign to an existing record.In form1 the user will enter data into a textbox. I use this information to build a bindingsource.filter. Then I call another form (form2.show()) to display results to user and get user response. This part all works correctly.
The problem is that as soon as form2.show() executes, I loose the contents of the textbox - and it appears that I am no longer in the bindingsource.addnew() method.

VS 2008 Form.Show / Form.WindowState?
Oct 26, 2010I have a dual monitor setup on my computer. My program has multiple forms. I've designed the program to check which monitor the main form is currently on and to open the secondary forms on the current monitor. When the main form is on the primary monitor the secondary forms open as FormWindowState.Normal which is the design-time setting for the secondary forms. If the main form is on the secondary monitor and I click to open a secondary form then the secondary form is to be displayed as FormWindowState.Maximised.
[Code]...
So I moved the Form.Show line to after the Form.WindowState line. This works fine when the Form.Show process is very quick. The problem is that one of the secondary forms downloads some information from the internet so it takes about a second to finish the Form_Load process. When I had Form.Show first the form would not appear on screen until the Form_Load process is complete, so the delay was in the form appearing at all which is how I prefer it. With Form.Show last the form appears on screen immediately but appears mostly blank and unresponsive until the Form_Load process completes.
I would prefer that the form not appear at all until the Form_Load process is complete but I would like it to appear in an already Maximised state. Is this achieveable? It doesn't seem that complicated but I just can't figure it out.
