I have a program that prints raw code to Zebra printers. We are adding some Intermec printers. So I would like to be able to pull the Model of the Printer (selected from a standard printer dialog) and use that to chose the code that would be sent to the printer.

I already tried using the "PrintDocument.SetDevMode". it seems not be working.
1. Detect if my printer is busy, because my code tells the printer to print more pages that it can cope with, so I need to delay the command for 'Print the next page' until the printer has finished printing the previous one.
2. Shift the output to my printer so that it gets printed in it's entirety on the paper, instead of seemingly being anchored to some nebulous point on the A4 page. It starts printing at X = 29mm from the left edge, and Y is 28mm from the top, and stops at X = 22mm from the right edge and Y stops at 22mm from the bottom edge, leaving (aprox) 50mm of X and 50mm of Y unprinted.
3. Get useful information on Bounds, which I'm fairly certain is what I need to control where my printing should start and finish.
I've hunted through this forum, MSDN, 'Help' (a misnomer if ever there was one) the VB Library and one or two other forums, which either baffle me with reams of code or suggest code to try which either just don't work or which doesn't declare all the variables and usually don't suggest what type of variable I need, it's all very frustrating

View 2 RepliesAssuming an architecture as such.MODEL > BLL > DLL
Trying to implement lazy loading in my MODEL I have run into a circular dependency between my MODEL and BLL..Basically imagine a property in my model that I want to implement as follows
Public Readonly Property ProjectCategory As ProjectCategory
Get
If Me._ProjectCategory Is Nothing Then
Me._ProjectCategory = ProjectCategoryBLL.GetProjectCategoryByID(Me._ProjectCategoryID)
End If
[Code]...
I have my MODEL, BLL and DLL in separate projects and because of the fact that my BLL references my model I can not reference my BLL from my model as this would create a circular dependency.
I'm quite new to MVC and while I've been trying to follow the best practices , I believe I may not be understanding certain fundamentals of either
-a. Using models and viewmodels appropriately
-b. Passing models into a controller for validation purposes.
The general purpose of my program is to select a stored procedure from a list of stored procedures, create a form where the user can fill out all the appropriate input variables, and then to execute that stored procedure. The tool is for non-technical people, so I'm eventually going to have to do a good deal of input validation.
As such I have four models: A Script Model, a Parameter Model, a Parameter Enum model and a Query Model, and two viewmodels: a paramviewmodel that generates the form to fill out, and a scriptviewmodel that creates a listbox filled with the possible script choices. I am using a prewritten database system to fill out my viewmodels in an init method in my controller (which I'm not sure is the proper way to do this?).
The viewmodels are as follows:
Imports System
Imports System.Collections.Generic
Public Class ScriptViewModel
[Code]....
I'm trying to work out the functionality. Also, I think this may be too much code in the view, even though most of it is display code.
Anyways, I have two main questions. One, does creating a model in my controller, calling an init method on it, and then passing it to the view make any sense in an mvc context (if not, how would I proceed?). Two, if I want to perform validation on the form I output in my htmlhelper, but I want to use my query model validation (and not my paramviewmodel), how can I do that? Most of the examples I've seen involve a controller that recieves an appropriate model variable, and the binding is performed outside the controller itself. They then just check modelstate. Is there any way I could do something similar here?
Edit: Is there any way I can make the syntax highlighting less crappy?
I am trying to figure out the best way to implement a certain part of my model.I have an entity named Customer which has CustomerLocations (1-*) which have SalesOrders (1-*) which have Invoices (1-*).I want to allow them to have multiple addresses (Billing and Shipping) per customer and per location. I want to store those values in the sales orders and invoices, not a foreign key, what if they delete one of their addresses later down the road.I have tried complex types, but then they can't have multiple, can they? And having an Address entity, customer --> address (1-*) is ok, but a bit clumsy. How would you have a collection of billing and shipping addresses.?
View 1 RepliesI have a repository class that defines some basic Get/Save/Delete methods. Inside these, I use NHibernate to do the work on my business entities. For example:
[code]...
However, on my User class I have some properties and collections of other objects that ideally I'd like to be lazy loaded. But of course, the ISession is created and disposed within the repository, which I guess is why, outside of that, when I try to access those properties I get a "Could not initialize proxy - no Session" error.Is my only option then to disable lazy loading when using repositories? Or is it possible (or just foolish) to somehow get the session into scope in the business layer?I do like the repository model, and NHibernate is growing on me (after lots of initial frustration trying to make it work), so what's the best way you gurus have found of using them together?

To make this easier I will use a concrete example using movies and genres. A genre can be associated with many movies. Genres can increase over time and so can movies.
The use case is as follows. The user wants to filter movies by selecting his/her desired genres.
So, I have a page where at the top there is a section where the user can pick any combination of genres to filter on using checkboxes. Below that is a list of movies that are in those genres.
In MVC I am trying to implement this using a ViewPage(of IDictionary(of Genre, Boolean)) where the boolean is whether or not a particular Genre has been selected for filtering.
I then go into loop that creates checkboxes for them to select:
<% for each genre As KeyValuePair(Of Genre, Boolean) in Model %>
<%=Html.Hidden("genre[" & i & "].Key", genre.Key.ID)%>
<%=Html.CheckBox("genre[" & i & "].Value", genre.Value)%>

I am aware this can be done using Ajax and I will most likely do it using Ajax but I would still like to know why this doesn't work.
I have a misunderstanding somewhere with the Entity Framework. This code is from my unit testing:
Public Sub UpdateRosterLinkTest()
Dim target As PlayerAdmin = New PlayerAdmin()
target.PlayerAdminManager = playerAdminTestManager
target.Team = playerAdminTestManager.GetAirForceMensBB()
[code]....
When I run this code, I can see the changes saved to the SQL Server this pulls from (RosterLink = Roster Link, like I set in the unit test).However, my unit test is failing, because team.RosterLink is still Nothing. The function GetAirForceMensBB() returns the Team with TeamId = 12434:
Function GetAirForceMensBB() As DAL.Team
Return (From team In Container.Teams Where team.TeamId = 12434).SingleOrDefault
End Function
I'm sure I'm using the entity framework incorrectly and it probably has something to do with the fact that I am calling the PlayerAdminTestManager in different places, but I don't understand why. Although, I set the PlayerAdminManager to be the PlayerAdminTestManager. PlayerAdminTestManager extends PlayerAdminManager, fyi.Why is team.RosterLink not showing the update from UpdateRosterLink?
EDIT:Container is my ObjectContext. This is how I access the information stored in the database.Container.Teams represents my Teams table.

I am in the process of using a two-dimensional array to find wind chill factors. My application uses a nudTemp for temperature and nudWind for Wind Velocity. When temp and wind are chosen from the nud list, it is supposed to display the wind chill temp in a text box and then display a message box. Right now it does everything it is supposed to do except that it does not display the proper wind chill factor.
I know it is an issue with my arrays so I was provided with an example but I don't know how to modify it so that it matches my code. I have added all of the array values but it is naming the array variables I am having issues with.
