VS 2008 Handle Saving User Control Settings On Form Close?
Dec 27, 2009
What is the correct way to handle saving user control settings on form close. I have a tabcontrol that a user can add tabpages during runtime. The user control has a few controls (listbox,combobox,textbox) How can I save the created tabpages and the data in each control in the usercontrol? Below is how I am calling my usercontrol
Code
Public Class TabPageEx
Inherits System.Windows.Forms.TabPage
[code]....
I seem to be a little lost as most documentation seems to suggest that I can not save usercontrol settings in the app.config. I have played around with the solution expl. settings tab without much success. But, then again I may be going about it all wrong. So, I am looking for a little direction on the best way to handle this on form close.
Okay so i have a problem with saving the users settings. Okay i have about 50 check boxes on my frm1.So for example if the user clicks on check boxes 1 and 2 the next time when the user starts the program i want check box 1 and 2 to be checked
I need to save some string settings at runtime and read them back. They will need to be changed at anytime during runtime also. The examples I have found says they are obsolete for vs2008. how to save and read some string settings? I found alot for the application settings that to me are ones you set once for the app like in an asp.net site. I need to change these anytime like you would in a registry.
I have a form with 31 checkboxs which i want saved when the user exits the form and two other buttons, One 'OK' and another 'Cancel'How do i save the checkbox settings when the user clicks the 'OK' button and not have them saved automaticly when the user exits the form?
I have setup the controls in the Settings of the application properties, i just need to have the checkbox checkstate saved only when the user clicks the 'OK' button and not saved automaticly by my application.Below is some code with the OK button that saves the settings and the Cancel button.
I have set up a notify icon for my form. I want to make it so that when the user clicks the close button that it doesn't close the form it just takes it to shows the notify icon. They can exit the program from the notify icon. Can someone tell me how to keep it running?
I'm writing a search tool. Setting the search parameters requires adjusting the values of over 70 different controls on my form.I want to make a list of saved searches. Is there an easy way to do so? Does VB have any built in features to save and load the current values of every control on the form?I could code it by hand. But this would be tedious, especially up to 15 listboxes, where I would need to save each item in the list and note whether they are checked or not. I really hope VB has a way of saving the entire form at once.
A while back, I wrote my own settings provider because I was having problems persisting settings in a class library. (Note - I had no problems persisting settings from an application).Today, I just did a test of persisting class library settings and it worked, without my custom provider.The test is:
(1) Create a class library
(2) Add a setting - 'Name'
(3) Add a class with a public shared property 'Name' that reads and writes to the setting 'Name'.
(4) Create an application that references the class library, and use the shared property to read and write the 'Name' setting.
I'm sure that before the 'Name' setting would persist while the application was open but after I closed it and re-opened it, the setting would revert to the default.This is not happening now and I'd like to be sure that I was being an idiot before and not an idiot now.
ETA: I've noticed that the first time I create a test app, change the setting, close, and reopen, the setting is not persisted. Subsequently it is. May be I gave up after one try before. Any ideas why it's not persisted the first time?
ETA2: As an example, I have a class library called 'MyLibrary' and a test application called 'MyApp'. I do the steps 1-4 above, and below are the contents of the user.config file found at C:Documents and SettingsUser NameLocal SettingsApplication DataMyAppMyApp.vshost.exe_Url_vi5gjcooahbdm2ma3dcay0mkexu2suul1.0.0.0. Note: I did not touch the settings in MyApp;-
I have used the below code but its not showing the msgbox. What is wrong with this code ?
Private Sub frmSimple_Disposed(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Disposed Dim result = MsgBox("Are you sure you want to Exit ?", vbYesNo) If result = DialogResult.Yes Then me.Close() End If End Sub
I am trying to close my application and I have coded on the form closing, form closed events to call an exit form which asks the user for confirmation to exit or not. All works fine. When I press the X button on the winform things act different. On the main form where I press the X btn I store some user ID data that I use throughout the app. If I press cancel on the exit form that data is lost from the main form and cannot be used afterwards. So if the user pressed by mistake the X btn and then presses cancel on the exit form the application loses some stored data and many functions stop working.
I am rewritting my application to conform to ms standards. We used to save all settings to registry for user settings, servername, size and locations.so we are now saving them into My.Settings app.config the only problem is that each time there is an update clickonce will isntall the newupdate but now all settings are loist and user has to save everything all over again..
I am trying to follow the book here but it seems i keep getting stuck somewhere. registry has worked fine for years but i understand we must move on, but if stuff like this happens then i just wasted a long time converting all code to conform for it to not work..
I have my form checked if it's dirty when a user goes to close it. If its dirty is true, the user is asked if they would like to save the data. When they click yes, the 'save event' is called. The problem I'm having is trying to get the form to completly close after saving. At the end of the save I put in me.close(), but another form closing event is triggered. Is this the correct way to dictate having the form close immediately after saving the data or is there a better way? If it is, I must have it placed in the wrong part of my code. Immediately after the "success" dialog box is displayed, I am asked if I want to save the data again.
I use VB.NET 2010 I have created a user control which holds a few textboxes, where the user can find articles. This user control is added to several Forms (where ever the search is needed). I have to handle the key down event of the user control, but it isn't working... The usercontrols's Key_Down Event is never fired. - I have set KeyPreview of the form to true, then the Key_Down of the Form is fired.
I have a main form that has a button with which a smaller form is shown. Think of the smaller form as the Find/Replace dialog in many applications, such as Notepad. It's important that the form is (what I believe is called) modal. What I mean is that it always stays on top of the main form. I ensure that by calling the Show method with "Me" as the owner argument. Whenever the small form loses focus it will not disappear into the background but stay visible (albeit out of focus). If you don't understand open up Notepad and have a look at the behavior of the Find/Replace dialog.
Here's my problem: instead of actually closing the form when the X is pressed, I want it to simply Hide itself, so its position and the state of any controls (checkboxes etc) is preserved automatically.To achieve this I simply cancel the FormClosing event and Hide it:
vb.net Private Sub Form2_FormClosing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles MyBase.FormClosing
[code]....
To show the form, I use the following (note the (Me) to make the main form the owner of the form; this ensures that it remains visible even when it is out of focus):
vb.net Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Form2.Show(Me) End Sub
Now. When I run my project, and open the Form2 (small form), then hide it again (by 'closing' it), I can no longer close the main form (Form1)! It seems the main form cannot close when the small form still exists (albeit invisible)...?? When I don't use the Me argument in the Show method, I don't get the behavior I want. I know I can set the TopMost property to True but that will also cause it to become visible on top of all the other forms, even windows not part of my application.
I'm trying to save a setting I've defined under Project -> Settings -> FirstRun, type boolean, scope Application, default value, false,But it doesn't seem to work, this is my(the text box does not stop, every time I open the program it shows)
Private Sub Form1_Shown(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Shown If Not My.Settings.FirstRun Then
I have done this the other way many times as it makes sense (the page knows about the control as it has been added to the page and can handle the 'child' event)
Is it possible to do it the other way? I think not as the control doesn't know what page it is going to be on
The reason i ask this is that I have a modal popup on the page to ask users to login, and it is only when the user has logged in that I want my user control to go away and execute some code but I am not too sure how to tell the control this has happend?
I have the user control that is loaded dynamically. When the user save the data by clicking on the Save button, a raise event is passed.
Public Sub RaiseCloseEvent(ByVal sender As Object, ByVal e As System.EventArgs) RaiseEvent Close(sender, e) Debug.Print(String.Format("The control {{0}} was closed by {{1}}.", Me.Name, sender.ToString)) End Sub
In the save button I have called the RaiseCloseEvent as follows:
RaiseCloseEvent(sender, e)
Now, how can I close the user control form? Any Idea? I have used VB.Net language.
My question is , i have just made a project for my appointments like, Name,Date,Time and Notes and all viewed in a listview grid but how would i save the entrys ?Like to save 1 line i can easly use my.settings but how about mutliple lines ?Here is a screenshot:It would be best to save it into the program like my.settings or something
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim lSingleItem As ListViewItem
I have created several classes and i wanted to know who to store the data enclosed in the classs. For Example [code]If i wanted to store that value past the close of the application, how would I? I already know I cant use the settings class. And what if i have multiple new classes.
How do I save my programs settings in a document? Like total sessions used, Total accounts created. Also, How do I make a text file save and load every time the program is opened or closed? The saved accounts should be like this in the text file.
Account: Account name E-Mail: E-Mail used Password: Password used
Account name, Password, E-Mail will will all be in a textbox or combobox so if you can make it save from there. I have an total accounts created combobox. How would I make that load into a combobox and then when session is closed they all save. So loaded into a combobox then saved into a text file.
When I save settings for an application using My.Settings.Save it saves it in %AppData%LocalCompanyname. Because I don't want my app to be installed and I want it to be a just .exe file, and it leaves some files on that computer. I like it to be in my apps location. Can I change that default location?
I would like to create a program that user can save his settings in the program and not on the computer .I want to make something like icon changer ιnstead it will work for strings not icons String Changer?
ok, I have a "sum" for ading the total prices in list view. The prices are in the sub items. After they are added up ( they display as total: �{0}) how would I save them to add up later amongs other things I have saved in my.settings???
I want to give my end user the abilility to navigate to a web page, and then I need a way for the user to close the web browser control so that I can capture the final url. There must be a way but the obvious candidate (a property named "url" of the web browser control) is not there.
I have a Mdi form and I need to put a control on the form which the user can resize. Now I need a container can be dragged by user to increase it's size. The split container will not work in my case as I have childforms and stuff. I want a container whose size can be increased by dragging it on one side.
