MVC - Rendering Textbox For Complex Type?
Nov 2, 2011
I have been reading the various blog posts on how to deal with a Complex Type. However I don't really get it. I am using EF code first development, MVC and VB. From what I have read so far to render a editor field for a complex types requires a custom object, right? However I don't really understand what code I need to put into the custom template. What code needs to go into custom template so I can render a textbox for the PostTags icollection?
My classes:
Public Class Post
Inherits EntityBase
<Key()> Property PostId As Integer
<DisplayName("Title")> <Required()> Property PostTitle As String
<UIHint("MultilineText")> <DisplayName("Text")> Property PostText As String

I am using IIS 5.1 on server 2000. I have set the asp.net page for custom error in IIS which is directing to C:InetpubwwwrootCustom_ ErrorIIS_Error.aspx. Custom error page appears when user keyin wrong password for 3 times.When i access the error page directly (for testing) from my laptop using following URL then i can see the page text and the text box.
//192.168.0.10/Custom_Error/IIS_Error.aspx
But when user keyin wrong password for 3 times, system shows the custom error page with text only and doesn't show the asp.net controls.Also, is there any way to show the local path from where the user has been redirected to the custom error page? For an example; we have got 10 folders under website called TestWeb, so when the user is accessing folder number (3) called webtest3 and custom error page should show webtest3 on the page.Can i do it either on asp.net or on asp classic page?

Working on some UI stuff, but I am having a problem drawing 'Top rounded' rectangles when the two top corners are rounded. I have methods to draw all four corners rounded and bottom rounded rectangles and they render fine.
I have attempted the graphics methods in CreateTopRoundedRect() in a variety of different orders, drawing the other corner first, the bottom line first, the bottom line before the left line, etc. In this function you can see a diagonal line splitting the shape. If you were to switch the bottom and left lines only half of the shape would be filled.

I'm getting a strange problem with an ASP.NET web application that is in production. The problem is that pages intermittently don't render correctly (see screen shot below). It isn't one particular page in the application or one particular use that is having the problem.

I'm trying to bind UI controls to a business object exposed as a property on an ASP.NET page in a null-safe manner.Using the 'If' operator is null-safe, but results in compiler error:
Compiler Error Message: BC30201: Expression expected.Using 'IIf' succeeds, but isn't null-safe. I've tried both the render expression syntax ('<%= %>') binding expression syntax ('<%# %>'), but there was no difference.Can someone explain this inconsistency and perhaps provide an alternative?
Sample code:
This works:
<%=IIf(Me.Foo Is Nothing, "", Me.Foo.Id)%>
This throws the compiler error:
<%=If(Me.Foo Is Nothing, "", Me.Foo.Id)%>

I am having a problem setting up my combo box to pull its menu from a SQL Server table and store to the main data table.Currently my drop down list displays correctly but saves 'System.Data.DataRowView' to the data table. My main data table is called 'Survey' with staffname as a column, then I have another menu table of staff member names which populates the drop down menu.I found that when I remove the DataSource and populate the Items collection instead the combo box saves the correct value as expected but when I use the datasource it saves the words ''System.Data.DataRowView',[code]

In my spare time i give myself programming stuff to do. Today i want to write a function that goes through a string, if the string contains any numeric value the function must return false, if the string has any special characters it must also return false else return true. For example the following strings would return as follows:
String Return Value
Travis True
78* False

I am currently working on a project, which purpose is to call a webservice through a VB script. VB is by far not my first language and I simply reach the point where I do not know how to go on from here.
I have a Webservice descriped in a WSDL document that defines a service that takes a complex type as parameter and returns such one as answer.
The complex type is basically just a string that is wrapped inside a class object. So what i did was to create a new class module and added a public variable to it. I created a new instance of this class, gave it for the purpose of testing a value and tried to call the webservice. Everything goes well untill i reach the call to the webservice, where the program throws an exception that says:
"Class does not support automation or does not support expected interface"
My first thought was that the initialization of the object might have gone wrong but i am quite able to set and get the values on it. So i have to assume that the object is okay. I know that the url to the WSDL document is correct, due to the fact that I can call the document via the browser and it will throw an exception of "wrong type" when i feed the soap method with a primitive.
With out luck I browsed several pages on the net to find a clue what this could. So now i wanted to give this forum a shot.
You should know that i am not able to alter the WSDL file. I have to go with the way it is. In addition am supposed to stick to VB 6.0.
I used a Form in VB to make the call to the webservice.
Here is the call procedure:
Private Sub Command1_Click()
On Error GoTo ErrorHandler

I have a custom modelbinder built to handle my accountRequest class.This class consists of some boolean values and a UserViewModel.The UserView Model is made up of strings such as Firstname, Last Name, Address.Originally I was just passing the UserViewModel as the action parameter but I now I need to package UserViewModel inside of accountRequest.however, now my modelbinder will not map the strings in the httpContext.Request to my UserViewModel inside of AccountRequest. All of the booleans map just fine.Is there an easy way to get his data to map to the UserViewModel properties other than hardcoding it? [code]

I'm trying to save some settings in a complex object. If I make a dll of the class I can then add it in the projects properties settings list as that type.When the program runs though it won't show up as anything other than nothing. I read you have to have a sub new empty constructor which I have but don't know why else this would fail.First question is how to you do this. Second is there anyway to use a class inside the project as the target of the settings type or do you have to bring a in an external dll to do this every time? [code]

I suppose this is more of an opinion question, but, when you start a big project, what do you think about before you even start Visual Studio? Do you setup structure and files before actually coding them, or do you code them one-by-one?

I have a web application that works in our stage/test environment fine but once we moved it to our production environment something weird happens. All the control ids change. a label went from ctl00_cphMainContent_lblPetName to _ctl0_cphMainContent_lblPetName. Why would this happen? What could cause something like this to happen. The only two differences I know of are the production environment has HTTPS and I've disabled debugging.

I'm wondering what the best way to render a scene made up of multiple-sized tiles, from back to front, with different heights. [code] Objects are sorted based on not their initial X/Y value, but their X/Y+Height value. That way, objects are rendered based on where they 'touch' the playing field. E.g., X/Y = top of a tree object, X/Y = trunk of the tree object.People (including the player) will be just normal map objects that get rendered and updated within a huge sorted list every frame. Right now, fudging around with my code allows my Player (32x64 pixels) to stand infront of a building but has her feet get overlapped with a patch of grass, which doesn't work. However, changing the sorting algorithm makes the player disappear in the building but you can see her feet.Also, should my players be included with the list of map objects? Granted, these will only be graphical representations of their data stored elsewhere (won't be cleared when map changes), or should I throw them into a whole new rendering list (which might open whole new problems). url...From what he says, he has 4 different layers and then draws the actor between Layer 3 and 4, with layer 4 being objects that will always appear on-top of the person.So, it appears that his player isn't a map object but an actor rendered separately from everything else.

I'm having a few problems with the layout of my new browser. I have a WebBrowser control which is docked 'Fill', and a MenuBar at the top docked 'Top'. When I run the program and go to Google (which has a dark bar at the top), a white gap becomes visible. I think that this is because the MenuBar's RenderMode is set to 'System'. When I click on it in the editor the bottom of the background is a few pixels away from the MenuBar's bounding square.Also, the MenuBar's RenderMode has to be set to System other wise the control is drawn as a rounded-rectangle and there are gaps in the background image in the corners. That said, I could change it, if someone could provide a solution to showing the background image in another control and set the MenuBar's background to transparent.
