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()
End Sub

Change All Properties Of A Form To Properties Of Other But Don't Change Important Properties?

Get Custom Properties For A Custom Control Into The Visual Studio Properties List?

Using 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'".

View 17 RepliesHow To Use Get/Set Properties
Apr 14, 2010I am using an array with four elements and I need to know how to do the get / set properties in the vb 2008 syntax.
When I try the above I get the error 'no longer supported. use the new property declaration syntax"
When I create a new instance of the class I would like to be able to set what is in each element in the array inside the form.
Here is what I have, without the finished get / set properties:
Public Class StdCondition
Public FilePaths(3) As String
Public stdImageList(3) As ImageList
[Code]....
So how would I set what goes into the array after I have created a class?
Background info: I need the array to store filenames (as strings) that point to images located on the hard drive. I will then use the imagelist, populated with the filenames from the array, to display the images on the form. (I hope to add the images to the image list with code inside my form)

C# - How To Serialize Only Some Properties In .Net
Mar 15, 2010This is for a web project so i have several classes that inherit from Web.UI.
I only want to serialize very particular properties (basically, only local properties)
I'm aware of the XMLIgnore property that can be placed on a property to ignore items, but this won't work in my context since that would require modifying a bunch of stuff that i really don't want to modify (and probably can't).
So how do i tell the xml serializer to ignore everything except for X and Y or tell it to seralize just X and Y?
i could just create my own xml in a string builder or something and if that's the only way, so be it. however i'm looking for a method that will employ the built in XML stuff.
Can XML ID Properties Be Duplicated

Class Properties Won't Set?
Jan 22, 2010as you might guess from the variable names I'm making a game (but this problem isn't game related!) which involves multiple "bullets" moving along straight trajectories. This is my attempt at changing my code for firing one bullet into one for firing many bullets at once. It works perfectly except for one thing.The class I made (BulletClass) to contain all the things needed to move the bullet isn't setting all of its properties correctly. I apologise for the walls of code however I wasn't entirely sure whether I should chop bits out. I wanted to colour code my code so that you could scroll through and see the subs where things have gone wrong, but apparently I can't even code a new thread. Let alone a video game. Instead I'll just list them, you can search for them if you like or just scroll through at your leisure.
[Code]...
In a nutshell: the properties TargetPosY, TargetPosX, ShipPosX and ShipPoseY are not working properly. As a result the calculations involving them are skewed and the bullets always travel directly downward.
