Change Path To Save Mysettings?
Apr 15, 2010I am using mysettings to save user settings.
This config file is saved in this path:
c: Documents and
Settings [Local
Settings] Application
Data\
Is possible to change this path? For example, in my case I save app data in "ProgramData" folder (Vista & W7) and I would like save this config file in the same folder.

Apr 27, 2010At first I was using this as an extension method to update my detached entities...
Public Sub AttachUpdated(ByVal obj As ObjectContext, ByVal objectDetached As EntityObject)
If objectDetached.EntityState = EntityState.Detached Then
Dim original As Object = Nothing
[code]....
Everything has been working great until I had to update non-scalar properties. Correct me if I am wrong but that is because "ApplyCurrentValues" only supports scalars. To get around this I was just saving the FK_ID field instead of the entity object relation. Now I am faced with a many to many relationship so its not that simple. I would like to do something like this...
Dim Resource = RelatedResource.GetByID(item.Value)
Condition.RelatedResources.Add(Resource)
But when I call SaveChanges the added Resources aren't saved. I started to play around with self-tracking entities but it seems they cannot be serialized to ViewState and this is a requirement for me.how to either save my many to many relationships or serialize self-tracking entities?
Put Form Size In The Mysettings Of Vb2010express Application?
May 19, 2010I've been tortured with this question for few days. As I understood, you could put some of form's properties to mysettings, actually binding them with some named values as strings.It's not very hard, and it was well documented. I tried it and it works fine.Only, not all properties are offered to be bound with mysettings, only some of them. For example, you could bind starting position and windowstate, close your application, and when you open it again, it will open the same window on the same place on the
View 4 RepliesSwitching Database Dynamically - MySettings.Connection
Oct 20, 2011I have a connectionstring in MySettings which all my datasets use. The project has three copies of the same database: LIVE, WHATIF and TEST. I need to have a dialog in my startup that asks the user which db they want to use and then I thought I could amend MySettings.Connection string dynamically. Hey-ho it's read-only! Is there any other approach I can use where I change a connection string once and all my datasets will then point to the selected db?
View 3 RepliesVS 2008 Save Combobox Items In MySettings?
Jun 15, 2009Well currently I'm needing to store various settings, strings, integers, items, etc, within the program settings. So far this has gone without a snag and is working as planned except for one thing, Comboboxes. I have browsed through the various types of settings I can save to and the closest is a "System.Collection.Specialized.StringCollection", however VB is throwing up an error saying that:

Error1Value of type 'System.Windows.Forms.ComboBox.ObjectCollection' cannot be converted to 'System.Collections.Specialized.StringCollection'.C:UsersUserAppDataLocalTemporary ProjectsProjectForm1.vb1234Project
How would I go about saving the items in a Combobox?

Authentication - .NET - Accessing MySettings.Default Changes Thread.CurrentPrincipal?
Nov 14, 2011It appears that when you access My.Settings.Default in VB.NET, your thread's CurrentPrincipal changes. Consider the following code.
[Code]...
Is this expected? Is it documented anywhere? I couldn't find any references to it.It also seems to only do this the first time My.MySettings.Default is accessed, which means that a workaround might be to touch the property to initialize it before attempting to set the thread's CurrentPrincipal. Would there be any undesirable side effects to doing that?
How To Implement Find On IList And Update Object Properties
Dec 7, 2010I am declaring an IList:
Dim OrigVendors as IList
OrigVendors = new List( of IVendors)
I populate the OrigVendors variable and what I want to do is find all the objects that have the ID I am looking for. Then I need to update a property on that object for only the ones found. Is this do able with an IList or do I need to use some other type of collection? I am using VB.net.
Implementation - Loop To Update Properties Of Each Object Of A Set Of Custom Objects
Jan 4, 2010I am using a loop to update properties of each object of a set of custom objects. The routine knows which controls to update because the controls value is not empty, I don't want the routine setting the corresponding properties to nothing when the control is empty. Now I know how to do this perfectly fine with IF statements such as:
CODE:
But this feels really redundant doing that same IF block over and over for each property/control combination, I thought about creating a separate routine that takes the control as an argument and does all the repetitive IF blocks but I don't know how I could also pass an object property to tell the routine to update that particular property.

View 2 RepliesUser Control Properties - Finalize My Design Time Properties Grid
Apr 27, 2011I'm making a control and I am trying to finalize my design time properties grid. I have several List(of Class) items as public properties and when I click on the design time menu (while testing the control) there is the word "Collection" and a button with an ellipsis (...) that brings up a neat pop up with the buttons Add/remove and all of the public properties of the collection's class on the right hand side. Basically for a non-collection instance of a class (with public properties) I'd like a similar button to show up. I know I could put all of the properties in the main control class and group them, but I like the pop up box feature. Anyway to duplicate this? (think font grid item etc.)
View 3 RepliesVS 2010 Express - PictureBox Design Properties Box Shows Properties That Cannot Be Accessed?
Mar 5, 2012In the form design I set up a TableLayoutPanel, 20x20 cells and in cell (1,1) a PictureBox (called Target) containing the image of a small target. The properties box for Target shows some very promising properties, Column and Row - and if you overwrite the values in the properties box, the PictureBox obligingly shifts to the corresponding cell position in th design. However in VB it is not possible to refer to Me.Target.Row or .Column - neither appears during coding in the menu of properties, and deliberately coding either of them produces an error like
Error 1 'row' is not a member of 'System.Windows.Forms.PictureBox'.
1. Why does the properties box show properties that cannot be altered programmatically?
2. How can my program move Target around in the TableLayoutPanel?

View 3 RepliesSet The Transparent Property Via Label Properties Properties Not Via Code?
Jan 16, 2009I'm working on a Hazardous Materials label printing program. One of the options is to do an "NFPA" label. Since there are 4 values required with 4 or 6 options, the ratings are entered via radio buttons in a group box. That's working okay. I display values in the NFPA diamond as they're entered: left quadrant blue, top quadrant red, left yellow, bottom red. I'm having trouble with the label in which the rating will be displayed on top of a jpg diamond for the white. In this quadrant the text can be up to 4 characters. I can accept the text going into an adjacent block a little, but the corners of the label overlap into another quadrant/color. I reduced the font size which solved the overlap problem but the font is then too small and looks terrible. I tried to make the background of the label transparent to let the color come through correctly but that's not a valid value for label.background. I'm figuring that the transparent background is the best solution. What can I use that will accept a transparent background so the color shows through?
I'm trying to set the transparent property via label properties properties, not via code. Here's the code if it makes any difference:
Public Class NFPA
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Close()

View 2 RepliesUsing AutoMapper To Map DAL Properties To BLL Properties?
Oct 8, 2009I have a BLL class which contains properties for the fields in a Country table (CountryCode, CountryName, etc). It also has a property ioDAL, which is a reference to a DAL class (created with SubSonic 2.2), which has same named fields.
I have a LoadRecord() method which calls the DAL's FetchById() method that populates the DAL properties by calling the database (SQL Server 2005 FWIW).What I then want to do, rather than writing code to populate each BLL property from its DAL equivalent, is to use AutoMapper (from CodePlex). I think the line should be something like
Mapper.CreateMap(ioDAL, Me)()but this gives errors "Value of type (DAL class / namespace naming) cannot be converted to 'System.Type'" and "Value of type (BLL class / namespace naming) cannot be converted to 'System.Type'".
