i have uploaded 3 pics shows 3 diff forms.
1. BaseForm.( Includes 2 button, Buttons Text "Form1" and "Form2")
2. Form1. (Just inherited BaseForm)
3. Form2. (Just inherited BaseForm)
If the Button Form1 clicked then it shows Form1 disable Form1 button. and Hide BaseForm. same action for Button Form1.
When I click the Right Top Cross button then the Background BaseForm Still running. I want to close all form If I click cross.
I 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?
Is there a way to prevent the Enter key from being interpreted as a button click.
I am trapping key strokes at the form level but if a button has the focus and the ENTER key is pressed I cannot trap the enter because the button consumes it as a button click event. I am also unable to trap the enter key in any of the button's key events.
I am interfacing with magtripe swipe and barcode readers that send their information as keystrokes with a CRLF at the end. I have a work around by chaning the focus to a textbox anytime keystrokes are detected but I am hoping for better control.
Is there a way to disable the buttons ability to do this?
How would I enable/disable a button if listbox become populated?
View 1 RepliesI have a login screen (frmLoginScreen) which links to a main menu (frmMainMenu) then to another form (frmUserDetails). Their are two possible usernames. The first one the user logs in as Admin and the password is 4321, then the second one is Guest and no password. This is the code I have so far:
Dim G As New frmUserDetails
If txtUsername.Text = "Guest" Then
G.btnDelete.Enabled = False
End If
There are no errors.
Can we disable the close button on a form ? I can remove the minimize/maximize, but cant find anyway to disable the close button.
View 11 RepliesI am attempting to disable the close button "X" in the controlbox of a form and keep the maximize and minimize buttons. There does not appear to be a way to accomplish this with conventional VB code or using the Form's Properties.
So I ventured into the realm of API's.
I declared the following API Calls and Constants:
Declare Function GetSystemMenu Lib "user32" Alias "GetSystemMenu" _
(ByVal hwnd As Long, ByVal bRevert As Long) As Long
Declare Function EnableMenuItem Lib "user32" Alias "EnableMenuItem" _

So what I am trying to do is to get textBox1 to show which button i have clicked. Because I have Form_Activated I only see changes when i reactivate the Form. So I would like to have Event that is Active all the time and listens to everything that happens in Application and NOT only when something is clicked or some text have changed.

View 4 RepliesI'm writing an MDI app in vb.net vs2010. The MDI form has the default MDIMenustrip menu with several menu items. Each has some subitems. None of the child forms have a menustrip defined. I thought it would be easy to call a public subroutine in the MDI that would disable or enable the MDIMenustrip items. If I execute the routine from the MDI form, the menu items disable/enable just fine. THe problem I have is when I call the routine from a child form. How can I control the MDI menu from a child form?

to open Tabpage 2 when i click button 1 on Tabpage 2, how to do it
View 8 RepliesI have a form to create staff.
Hence after a new staff created, user can click on new button at the bottom to show a new staff form and close the previous one (parent form).
I have the following code under new button click event but i found that the previous form (parent form) somehow is still held in the memory.
What is the correct way to implement this and make sure parent form is released from the memory every time i click on the new button?
Private Sub btnNew_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnNew.Click
Dim frmChildForm As New frmStaffCreate

how to show the tally using radio button on the next form
View 3 RepliesI have a simple login field, which works fine with the exception of one quirk. The form is set up with the tab order to go to the UserID first and the Password text box second. This works fine when the form is used the first time, but when the form is used the second time the focus in placed in the Password field. If the form is used a third time, focus is moved the OK button, that is each time moves to the next tab order. I even tried to set the focus in the Load event as in Me.txtUserID.Focus(), but this doesn't change the behavior. Again, I should note that I close the form and not hide the form.
View 3 RepliesI have been working on a quite complex multiform solution.All of a sudden the start up form (in fact any form I designate to start up) loads, displays and operates fine.
But when I try and show a form using showdialog the form displays behind the original form and I can�t set focus to the ide to close it down. I have to use task manager or alt f4 while the form has the focus.
Calling different forms from this one gives the same result but other forms work fine. I don�t want to redo this form as Ive done a lot of work onit.The only thing I can think of that whist I was changing the startup form in the project propertied page (file>project>properties) I unchecked the �Enable applications framework checkbox.
