Database - Create Model Container Object?

Sep 9, 2011

So I create the model container:

Private mdbContext As PFModelContainer
Private mdbTransactions As Object

Before I did it this way:

Private mdbContext As New PFModelContainer
Private mdbTransactions As mdbContext.Transactions

Thinking maybe I was doing something wrong I changed it over to the first way, then I do:

Public Sub New()
mdbContext = New PFModelContainer
mdbTransactions = mdbContext.Transactions
End Sub

Once I hit mdbContext = New PFModelContainer it takes me over to the PFModel.Designer.vb Where it steps through the following:

Public Sub New()
MyBase.New("name=PFModelContainer", "PFModelContainer")

At which point it terminates execution of the code. This is the error it gives me on the Immediate window:

A first chance exception of type 'System.ArgumentException' occurred
in System.Data.Entity.dll

Is there something I can do to make this error go away? I tried deleting the project and recreating it with my old .edmx model that I downloaded from Mozy from when it used to work. It stopped working (as far as I can tell) after I changed the .edmx model and updated it. Maybe I did something else in the other project too, but I'm not recalling anything.This is what is in the app.config:

<connectionStrings>
<add name="PFModelContainer" connectionString="metadata=res://*/PFModel.csdl|res://*/PFModel.ssdl|res://*/PFModel.msl;provider=System.Data.SqlServerCe.3.5;provider connection string="Data Source=|DataDirectory|inDebugMyDatabase#1.sdf"" providerName="System.Data.EntityClient" />
</connectionStrings>

Should I be referencing System.Data.EntityClient and System.Data.SqlServerCe.3.5 somewhere?The EDMX property Entity Container Name is PFModelContainer and the Namespace is PFModel.

Recommendation For Object Container

Sep 28, 2009

I need a recommendation for a data container. I am loading a sequence of letters (Latin characters) into a text string.I then want to pass the individual characters into a 2-D matrix-like container (i.e. populate left to right based on # column assumption).I then want to search for patterns within this matrix using rules similar to that of a crossword puzzle (Left to Right, Top to Down, Left to Right Diagonal).What is the best container to do the anlysis in?I am assuming the decision to this will be based on the search flexibility of the container.My initial goal is to use crossword puzzle rules as noted above.But I may want to expand this to search backward as well (ie. Right to Left).

Business Model Class Object Relationships And Communication?

May 7, 2012

I'm developing a business model for an application where I am representing physical entities. The hierarchy created from this is neat, but as I'm doing this, I'm beginning to think about things like, what properties should be included in one that may already be apart of another? Or what if some properties are expected to be in one object, but another object needs to return that value, how does it communicate that request through the hierarchical chain? And what is the best practice for this design?

[Code]...

But then I got to thinking, what if I have a ConnectionPoint entity and I want it to return which Panel it has? Should it have it's own Panel association as well? Or should there be a method/pattern for communicating the request up the chain? And again... what's typical best practice?

Sharepoint 2010: Updating From Client Object Model?

Feb 17, 2011

I am not sure where to post this as I didn't see a forum for SharePoint on here. I hope someone can help me with this.I have a form sitting on a webapp outside of the sharepoint server (which is why I am using the Client Object Model). To make a long story short the form is sending data to a SP list. This list is made up of regular string fields, date fields, lookup lists, choice lists and user data.

I am able to insert data that isn't part of a list with no issues. However, when I update any of the lookup lists i receive the following error:Invalid look-up value. A look-up field contains invalid data. Please check the value and try again. So I then wrote code that went to the list and got the entire item as follows (please bare in mind this is not very eloquent, but it gets the data)

Windows Script Host Object Model's Interop.IWshRuntimeLibrary.dll Referencing Same Directory As Executable

May 10, 2011

I have an application that creates desktop shortcuts. To do this I have to reference the Windows Script Host Object Model. When I add it as a reference, it always creates the DLL, Interop.IWshRuntimeLibrary.dll, in the objx86Debug directory, then references itself to it, rather than looking at wshom.ocx. Even if I add reference wshom.ocx it reverts to saving the file in the objx86Debug directory. The problem is if I move my application to another computer without that DLL being present, the program fails to run.

Create FK To Model, From Aspnet Forms Validation Tables

Jan 17, 2012

I've recently created a MVC 3 ASP.net application (using VB). I have also created forms validation by running aspnet_regsql. I used this to create the table in the same database as my application uses. I am trying to work out how to create a new model, with a FK from the Users table. Do I have to reverse engineer the validation tables to create models in my application? right now, the tables only exist on the SQL 2008 database, as they were created by running the aspnet_regsql command, and do not exists as models in my ASP.net solution. Here is the code I have now, for a model I would like to add a FK to (as a one-to-many relationship):

Imports System.Data.Entity
Imports System.ComponentModel
Imports System.ComponentModel.DataAnnotations

In Entity Framework, We Can Use Model First, DB First, Code First But How Can We Create Table Programmatically?

Jun 9, 2012

In entity framework we can use 3 approaches model first , code first , database first but each one of them needs manual hand touch(means creating database or create model or write the POCO class codes or entity class codes) before proceeding to the next step ( using EF in context ).What if I want to create database and tables and table relationships programatically and still want to have to features of EntityFramework 4.3.

To be more specific ,from this example http://support.microsoft.com/kb/307283 we can create database , tables and everything using SQL command but we can't have the advantages of entity framework. So if we want to have that what should we do? To give the ability to create dynamic table fields those steps will not be sufficient. In all 3 steps database , table and table columns are fixed. There is no way that a user can create new tables or columns dynamically. http:[url].... in this post , it shows how to create manual db, tables and etc using SQL but it is based on ADO.NET but I want Entity Manager to do that.

Client Object Model: Uploading File To Drop Off Library Doesn't Apply Content Organizer Rules

Jun 29, 2011

I am currently developing a service using the SharePoint 2010 Client Object Model to programmatically upload Excel worksheets to a Drop Off Library and then set the properties on the file. This process is working well. However, the Drop Off Library is governed by Content Organizer Rules that aren't being applied to the uploaded file. I have examined every property I thought I could have missed: [code] What's most frustrating is that if I edit the document properties using the Web UI and check it back in without making any changes, the file is moved to its final location. What might I have overlooked that is preventing Content Organizer Rules from being applied to newly uploaded files when using SP2010 COM?

Create A Digital Terrain Model From ESRI ASCII Grid Format Into An Array?

Dec 14, 2011

I need to create a Digital terrain model from ESRI ASCII grid format into an array. First I need to use the column and row values (from the header information) to read into my file to specify which values to put into the array. I think i have to use both counters simultaneously, and although Ive read in the first line (columns) I can't get the next line in. Do I have to use a counter under a different name, and can I do it in a nested loop?

vb.net
Private Sub Input_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Input.Click
dlgOpenASCII.ShowDialog()

Find "People's Contacts" Folders Via Outlook's Object Model?

May 24, 2010

I have some code that locates all the contact folders that a user has access to by iterating through the Application.Session.Stores collection.This works for the user's contacts and also all the public contacts folders. It also finds all the contacts folders in additional mailbox accounts that the user has added via the Tools -> Account Settings... menu command.

However, this requires the user to have full access to the other person's account. When a user only has access to another person's contacts, then that person's contacts show up under the "People's Contacts" group in the Contacts view. How do I find those contact folders that don't show up under Session.Stores?

In order to see the other user's contacts folder without adding access to their full mailbox, click File -> Open -> Other User's Folder... from the Outlook menu. In the dialog box, enter the other user's name and select Contacts from the Folder type drop down list.

Here's the code (minus the error checking and logging) I'm using to find a list of all the user's Outlook contact folders. I know this can (and maybe should) be done using early binding to the Outlook.Application type, but that doesn't affect the results. EnumerateFolders is recursive so that it searches all sub folders.

Dim folderList = New Dictionary(Of String, String)
Dim outlookApp = CreateObject(Class:="Outlook.Application")
For Each store As Object In outlookApp.Session.Stores
EnumerateFolders(folderList, store.GetRootFolder)
Next

Create An Object Of A Class In Which There Are Properties And Functions That Do Database Selects, Updates And Deletes?

Oct 22, 2010

how to implement UI, BL and DAL in a project the way that I see it as a requirement for some projects. The way I am able to do a project now is from a form create an object of a class in which there are properties and functions that do database selects, updates and deletes. Looks to me that doing a project like that is separating the UI from the DAL. In an update button click event I may call Obj. Delete (txtCustID.txt) for example. I don't understand the part of further breaking it down to include a Business layer; in which a vb solution is made up of three solutions.What goes in the BL?Does the BL call the DAL?

Create A System-wide Independent Universal Counter Object Primarily For Database Keys?

Apr 5, 2010

I would like to create/use a system-wide independent universal 'counter object' that can be called via COM in a thread-safe manner. The counter object will be passed an ID to identify which counter to return, handle the counting, 'persist' the count (occasionally), have reasonable performance (as fast as possible) perhaps capable of 1000 counts per second or better (1mS) and be accessible cross-process/out-of-process. The current count status must be persisted between object restarts/shutdowns.

The counter object is liklely to be a 'singleton' type object implemented in some form of free-threaded dictionary, containing maybe 10 counters (perhaps 50 max). The count needs to be monotonic and consistent, (ie: guaranteed unique sequential values).Each counter should have a few methods, like reset, inc, dec, set, clear, remove. As a luxury, I would like to have a variable-increment (ie: 'step by' value). To support thread-safefty, perhaps some sorm of critical-section or mutex call. It just needs to return a long/4byte signed integer.

I really want something that can be called from anywhere, including VBScript, so I figure COM is my preferred solution.The primary use of this is for database keys. I am unable to use autoinc or guid type keys and have ruled out database-generated counting systems at this point.I've spent days researching this and I have really struggled to find a solution. The best I can find is a free-threaded dictionary object that can be instantiated using COM+ from Motobit - it seems to offer all the 'basics' and I guess I could create some form of wrapper for this.

C# - Accessing Office Word Object Model Through Asp.net Results In "failed Due To The Following Error: 80070005 Access Is Denied."

Aug 13, 2010

I have developed a website that allows users to upload office documents then uses the office object model to convert the document to an HTML file that it then displays in an iFrame. I have, of course, included references to Office.interop.word, and the site works fine on my development machine. When I uploaded it to my production server the site functions fine until I try to upload a document. I initially got a similar error that said "COM object not registered". I realized that Word wasn't installed on my production server. So I installed word and now when the server tries to access the word object model I receive the following error:

Retrieving the COM class factory for component with CLSID {000209FF-0000-0000-C000-000000000046} failed due to the following error: 80070005 Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))

I searched the registry for the corresponding CLSID and found a corresponding folder. I added full control to the IUSR_ account and due to the persistence of the error I eventually added full control to "everyone" and ensured these permissions inherited down to the rest of the folder. I then added full control to IUSR_ and again eventually added full control to "everyone" to my microsoft office folder.

I don't know what other permissions to grant and where in order to make this "Access is denied" error go away. I must be granting them in the wrong place, because as far as I know I can't be any more permissive than "Everyone" "Full Control".

Label Size - Drag The Label Object From The Toolbox And Drop In The Tab Control Container

I have been using vb6 for a while, I am following a tutorial by MS to develop a basic application and a simple task cannot be completed for whatever reasons! The tutorial asks to drag the label object from the toolbox and drop in the tab control container. Then, go to the label size property and adjust the size to some different dimansion. Basic stuff, right? It won't let me do it! After I enter the new dimensions (which by the way are not large or very small), the label size (both width and height) resets back to its original dimensions! I have the vb.net sp1 installed.
