I have a complex form to allow the user to configure my app.
What's the best way to save the form state & reload when the program next runs.
I mean text he has entered in list boxes, the selected item of combo/list/radio, whether a checkbox is cheeked, etc
I experience very strange behaviour of a windows form written in VB.NET 2005.
The form contais DataGridView with data.
I minimize the form to Windows task bar, then I restore it. The form appears, but the DataGridView and other controls are not displayed. In order recover from this situation, I need to resize the form or maximize it.
I am creating a very simple game for a project. There is opportunity for bonus marks, and one thing I would like to do is be able to "save" the game. The only thing I need to do is save about 4 variables to be recalled the next time the program runs.
What is the best way to do this?
I have searched Google, and there are ways to link the program to an Access database, but that seams a little extreme. I tried seeing if you can make an XML file to hold them, but I can't really find any good information.
I have a search page in one form(Search.vb) and another form(Form1.vb) to display the details of selected data from the search form.
I already have back button in Form1.vb which returns to some other form say (Action.vb).
In case of searching data it returns to Form1 to modify the selected data, In this case if i press the back button in Form1.vb it should return to search.vb with the details that i entered for searching.
Is there any way to save and restore the form whenever needed with its details?
I've created a form with a PictureBox on it and would like to dynamically create another PictureBox on the form while the program runs (to the left of the static one). I've written this code:
Dim temp As PictureBox
temp = New PictureBox
temp.Image = StaticPictureBox.Image
temp.Visible = True
[code]....
When I run this code I can detect that the temp PictureBox does get created. However, it is not rendered onto the form. It seems like it's there but is invisible.
I have a form which has a ListView and buttons to add/edit/delete items from this list. It has a save & a cancel button. On pressing the cancel button, I want to revert all the changes that have been done in the current form. So, while loading the form I keep a copy of the original list like below.
backupMyListView = MyListView
In the cancel button code, I do the opposite.
MyListView = refMyListView
Whats happening is that, the original listview is never restored because everytime MyListView was updated, backupMyListView also was getting updated.
How do I restore the original ListView on pressing the cancel button?
I have an application that has a part of it that modifies several windows services. When the form loads it checks the registry for the current status of the services.
What I would like to do is have it so that the application takes a snapshot of all the defined services when it is first installed and stores the defined settings for each of them. This way the services can be restored at a later time to there original settines. I would also like to make it so that a custom settings file can be created so that this custom configuration could be loaded which contains changes. The result would be the first file made would allow everything to be reset prior to any changes the second file would contain all the setting changes.
Im having some trouble saving and restoring a TrackBars value to my settings.First of all, this trackbar is controlling a WMP components volume.. That works fine, no problems here, i can control the volume with no problems with this
Private Sub TrackBar1_Scroll(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TrackBar1.Scroll Volume.Text = TrackBar1.Value Form1.RadioPlayer.settings.volume = TrackBar1.Value
End Sub
What i want to be able to is for the application to save the value the Trackbar has been set to, when the application closes and the restore that value when it is launched again. And for this i use Application Settings.

View 1 RepliesI have made a program that has an intro screen, moving onto an activity select screen which acts as the main interface to get around the program. After creating the program and installing it on my computer, when I close the program from the activity select screen, using the "X" at the top right corner, the program continues to run under "processes" in the task manager.If I close the program from the intro screen though, it will close everything, including the processes. Is there anyway I can get the same to happen with the game select screen? I can make it work by putting my own "End" button on the form, but id prefer to be able to do it with forms own close button.
