So, I've created a form that allows for the user to save his or her settings after closing it. When using Visual Basics to run the program, there is no problem and it works wonders. When I run the program not in Visual Basics, when I go to open the form, it fails. At first, it was because I didn't update the configuration file to include the new settings. Which was dumb, of course, but I updated the file and made sure to put it with the program.
However, when I opened the program again, it failed. So, I tried putting an error message in the form so I know why it failed. This time, it would come back saying "Error Occurred. The Following Error Occurred:" and that is it. No details at all why it was having any problems reading my new user settings. Once again, the user settings work fine in visual studios. It has the updated configuration file in the same place it is.

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.
I am creating an application for a company and this CD will be distributed to hundreds of people. Many users will have different computer screen size and different screen settings such as their resolution set to 1024 x 728 and their monitor size 17" inches.
I noticed when I loaded the application on a different computer with different settings the application was to big for the screen and did not work. I notice that lot of other programs from microsoft resize their controls and text but never knew how they did it. How can I resize the form and control according to the user's setting.
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 created a user control with a label and 2 combo boxes, and a public property called ControlDataSource that accepts a dataset - which it populates the combo boxes with. I added the reference to the VB project I want to use it on and to the toolbox. I was able to draw it on the form with no problem and use it. However, after changing the backcolor on the control and recompiling it, it is no longer seen by the form. When I bring up the form it's used on, I get a white screen with a bunch of xml. The problem seems to be in the designer, and I get an "object reference not set to an instance of an object" error. Here is the code from the designer:
[code]...
The reference error is pointing to the line: Me.UcDx1.ControlDataSource = Nothing
Here's the wierd part. If I hover the cursor over that property, it correctly identifies it as a dataset. So it does know what it is, but it can't seem to use it.
I am jsut adding bits on to a Windows Service we are making here at our company, its an Asset Management tools with a few built in extras. It runs as a service on everyones machines but we can also do things like request a reboot etc through it.At the moment when We send a Reboot/shutdown etc command to it the Service on the machines calls 'C:WindowsSystem32Shutdown.exe' with the appropiate switches. This displays the windows shutdown warning to the users but nothing they can do about it.
What I was wondering if I create a seperate exe (or even better built into the service but I am not sure if this is possible) instead of the Service Calling 'shutdown.exe' it calls this form up to the user which states that we have requested a reboot etc but there is a 'Cancel' option. The Cancel can just end the form/program and nothing more, if the timeout that we specify is reached then that form/program then calls shutdown exe for an instant shutdown.
I know that the Service runs in a different user Space and we have no telling of who is logged on to that machine so I will need a way to just launch the form to any logged on users. Doesn't matter to much if there is no one logged onto the machine but if it does display this form while noone is logged on that is not a big deal.
1. I can't find the file which reflects changes to user settings. This might be because I just can't find it (I can see a bunch of user.config files but they are all empty - weird!), or...
2. I'm not actually saving them when I think I am.
Regarding 2. - do I need to invoke
Is this all I need? And if so, why are my user.configs empty?
I can double click on the Setting.settings and the projects Settings grid appears in design. I change the value of a user scope setting yet when I run the application in debug it picks up a value I set initially instead of the current value of the setting.
When the app starts I set a connection string to the path of the .SDF file that I set in the Settings.settings grid and accesss it with
mRootSDFPath As String = My.Settings.SDFConnectionString
how to reset user settings in My.Settings to the default value, because when i checked if the user settings works i have altered the settings so now i want the settings to go back to default, because i am going to distribute the software.
I am attempting to create an application in an attempt so it could be run as the user and preserve individual settings, by this what i am trying to achieve is when the application is installed, it is installed once but each user has their own settings saved within their own profile - a bit like Office applications. How could i start with this?
I'm trying to save a collection of key/value settings in my application's "user settings" (they're column widths), but while I see no errors, when I run the code (in the IDE) my collection in "My.Settings" is always nothing at startup. I do a "My.Settings.Save" when the application exits, and barring the "serializers not found" errors in the IDE, no other errors occur. When I run my application as an exe, it behaves the same way..
I don't even know where to begin describing this. I have a project, that uses settings, for some paths, settings that I retrieve with the My.Settings. function.In my laptop, when I change the .exe.config file, the settings are updated accordingly, but when I try that on the production server, it just shows the default value used while compiling.
I tried changing the solution configurations to debug and other custom configs with no effect.Tried to use the same folder copied and pasted without version control, still the same result.Tried a co-workers laptop, by using the last svn revision, it works there too. But on neither of the servers works.
I have some System.Collections.Specialized.StringCollection 's in my.settings and the won't do anything: I have tried adding things to them and I get a null reference, now I have used these before and they worked fine I have tried reading from them, like I have in the past, and it dosen't read anything; the strings come out emtey as in one emtey string when there is three full strings
I have a application that requires access to a tablet, the tablet in order for it transfer data accurately needs to be calibrated from time to time. Users have expressed intrest that once calibration has been done and has been validated to be correct that those new settings be ready for use in the main application. However, the only way I have been able to do this is to physically re-start the application. I have not had any luck with My.Settings.reload(). The settings I can confirm have changed but the application after saving them and calling the reload do not reload them. Am I doing something wrong? Does reload only work under certain conditions?
... the value remained the same, unchanged.1 thing though, my app is started via Sub Main() in module file, instead of "Enable application framework". Does this affect the saving of Settings file?
I am using VB.NET 2005 and running non embedded crystal reports from the SQL server and have following variables database name, server name, user name and password in the application settings editor and given the default values.
I have created a form that allows these settings to be changed by the user and the probem that I am having is that, the reports are still running with incorrect credentials. The following code runs when the user modifes the values and clicks OK button
I am a beginner using 2008 Express and I am trying to get my application to remember and restore some combobox values. It seems to work fine if the application is opened and closed normally but for some reason it loses the settings if it is opened from the startup folder.
Here is how the startup link is formed:
Dim shortcutFile As String = Environment.GetFolderPath(Environment.SpecialFolder.Startup) & "FBNav.lnk" If Not IO.File.Exists(shortcutFile) Then
I have an application that uses user settings and I have a button that gets a value (long) and writes this in a textbox I then have a setting called StoredKey with the data type of long I then pass this to the setting like this:my.settings.StoredKey=cLng(textbox1.text)this all works well in debug, but when I deploy my application and try to store the value in my.settings.StoredKey the value never gets written in!by deploy I mean packaging the exe in a setup and deployment project type and performing the wizard install to c:program files.[code]
I have a NumericUpDown Control on a form. In the Application Settings / Properties Binding, for the value parameter, i can't select my USER setting called : Heures (Integer / User).
[Code]...
But it's not saved.No problem for other settings (String / User). But i don't understand why the settings (Integer / User) are not saved.
I have a Boolean, user scoped setting. I access it through a referenced class library, called Settings. This class library has a Module with properties:
[Code]...
While the code is running this works. But after a restart of the application the new value is not persisted.
I'd like to know if there's a better way to read/write various user settings to disk. My program loads up a bunch of settings during load but also during execution from a few different forms, encrypted string values, boolean values, different types. The code seems to work okay but I have a feeling it's just not the best way to be doing this. Some of the settings are encrypted strings that have to be decrypted/encrypted so the code to read/write the text file is a bit different on some items. The data read from disk usually goes to a public string, a textbox, or a up/down type control. Below is about 1/10th of the settings that get loaded/written at various times. Anyone have a better way that might be more efficient that I should look at?
This has 2 ComboBoxes, 2 Buttons, a FontDialog & a RichTextBox.The code I used :
Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load ComboBox1.Items.AddRange(New String() {"London: 51N30, 00W07", "Paris: 45N38,5E44", "Colombo-Sri Lanka: 06N55,79E50", "Chennai-India: 13N05,80E17", "Sydney-Aus: 33S53, 151E13", "Toronto-Canada: 43N40,79W25", "New York-USA: 40N42,74W00"})
I am trying to save a custom object as a user setting in a VB.net app. This object consists of a List(Of Pair(Of String, Object)). Pair is a custom class which has two read/write properties (a String and an Object).
If I put simple types like int, string, datetime as the second value of my pair, the setting is saved without any problem. But if I try to put something more complex, like a list, there seems to be a problem during serialization and my setting is not saved.
String values in my pairs are serialized like this:
<value1>Priority_1</value1>
Object values are serialized with a special attribute:
<value2 xsi:type="xsd:int">2</value2>
Seems like values of type Object are serialized differently, to "remember" what is the real type of the object. Why can't it do the same for more complex types like List(Of T)?
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
