View 3 RepliesHow To Display A Bitmap On Form, And Then Remove It At Times, And Put It Back Again
May 13, 2009I want to display a bitmap on my form, and then remove it at times, and put it back again.
I have the Bitmap in my resources folder.in my form properties, it is selected as background image.
somewhere in my code I set the background image to = nothing (that makes it disappear) but every time I try to bring it back, I get file not found.I got it to display when I hard-coded the entire path and filename.[code..]
Obviously, when I publish and distribute to clients, the file won't be there.[code...]
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?

View 1 RepliesMultiple DataAdapters - Changing One Dataset On A Form Cause All Of The Datasets To Show Changes?
Jul 12, 2010I have a form with multiple DataSets (filled by multiple Stored Procedures) and corresponding DataAdapters. Associated with the DataApters are commands for UPDATE, INSERT......... Before using the DA Update I am using 'If DSxyz.HasChanges(). It seems that when I make a change anywhere on the form affecting 1 dataset, all of the datasets show this to be true. Why should changing one dataset on a form cause all of the datasets to show changes?
View 1 RepliesVS 2010 - MessageBox.show - Maintain Execution And Display Status On Second Window / Form
Dec 2, 2011I've created a form with several controls to specify the inputs to my program. They include TextBox, OpenFileDialog, Button and even a user control for numeric input. When the user clicks the 'GO' button, the program begins it work. Opening several files and processing a bunch of numerical data. This could take many minutes/hours with large datasets.
What I've been trying to do is have another window/form open up and send status information to it for the user to view. The info to be displayed is varied and constantly updated as the program crunches the numbers. Many many programs do just this type of activity.
I attempted to create a second form with a huge TextBox thinking I'd just write stuff to it. I called the .show method within the .click of the 'GO' button and of course the form is displayed but control of the program's execution doesn't return until the form is closed. How to I maintain execution and have a second window/form to display status?

.net - Singleton Initialized Multiple Times
Jun 27, 2012So I took this from an example. GetInstance() is called from hundred different places in my program, and when I debug, the line "Prog = New Program" keeps getting hit for each of those calls. Which I thought was exactly what should NOT happen.. Or do I have some fundamental misunderstanding?
[Code]....
It seems the "New" sub triggers a number of calls to Program.GetInstance, before the first one completes. This is due to me earlier having lots of shared public objects in this class, which are no longer shared since the class was made singleton. And these objects, when initialized, calls the Program class for reference to other of it's objects.

VS 2008 - Getting Data From DB Multiple Times
Nov 25, 2010I have a button where I get data from a database that matches a search string I enter. Everything works fine the first time the button is clicked. However, if I click it again with a different search string, I get the same results as the original search string. I've tried to dispose, clear, and reset my dataset before I load the data each time, but it still finds the original query. This is the code I use to get and request the data:

EditingControlShowing Events Firing Multiple Times?
Feb 24, 2009I have a DGV in VB.Net 2008 connected to an Access DB table. The DGV is not Read Only, but is full of read-only columns except for one, which contains a combo box. The combo box allows the user to select an outcome for that particular row, and then the program copies in a pre calculated value into the "Profit" column depending upon the item selected in the combobox. Then the user hits the Save button and the DB updates (currently via SQL methods in the XSD).
Easy enough so far.
Here is the code.
Private Sub DGUserBets_EditingControlShowing(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles DGUserBets.EditingControlShowing
[Code]....
The problem I have is that it would seem that if a user selects the desired outcome from the combobox but does NOT hit Enter, and simply mouses on to a different combobox to again select the outcome for a different row, the first eventhandler is not disconnected and thus the events fire multiple times. This then causes various default MsgBox errors and brings up problems when the user tries to commit all changes to the DB/exit program etc etc.
What do I need to do? Do I need to .EndEdit somewhere appropriate to force the row to save the changes? And where should I call this?
Events - SelectedIndexChanged Firing Multiple Times
Apr 25, 2012I am trying to programmatically add an unspecified amount of new UserControls to a form. One will be added every time an entry is selected in a ComboBox contained within the UserControl. Problem is, the SelectedIndexChanged event fires completely erratically. Sometimes twice, sometimes 3 times, etc., but never just once. No matter how many times I set the combobox's SelectedIndex to -1, it fires at least once with a SelectedIndex of 0. Sometimes the Itemselected event fires multiple times inbetween SelectedIndexChanged events.
InvoiceEntry.vb snippet:
Public Event ItemSelected As EventHandler
Private Sub cboItem_SelectedIndexChanged(sender As System.Object, _
e As System.EventArgs) Handles cboItem.SelectedIndexChanged
RaiseEvent ItemSelected(Me, EventArgs.Empty)
End Sub
