Columns Appear In Alphabetical Order In Data Source Based On EF4 Model?
Jul 13, 2010
I use Visual Studio 2010 and SQL Server 2008 R2. I have created an Entity Model in a class library which I have referenced in a VB Winforms project. I created a data source in the project based on the entity model in the dll. However, all columns in the data source are listed in alphabetical order instead of the native order from the SQL Server database. I cannot locate the cause of this as much as I try.
This might not seem a huge problem, but it is costing me valuable time in rearranging controls dragged to forms and reindexing their tabstop indexes.

I am using LINQ queries inside a WCF service to return data to a Silverlight frontend. Problem is the columns being returned using LINQ are in alphabetical order and I want them the way they are ordered in the database instead. Does anyone know how to stop the alphabetical ordering of column names?

I am creating a project in VB.NET in which one of the reports require that the name of employees should be displayed as column names and whatever work they have done for a stated period should appear in rows below that particular column.Now as it is clear, the columns will have to be added at runtime. Am using an ODBC Data source to populate the grid. Also since a loop will have to be done to find out the work done by employees individually, so the number of rows under one column might be less or more than the rows in the next column.Is there a way to create an empty data table and then update its contents based on columns and not add data based on addition of new rows.

I have the following code that sorts a number of names in alphabetical order(A to Z) Q,
1-How do I change it and make it from Z to A??
2-How do I cut back on the number of loops by placing -1 or whatever, because when I do that I tend to get a messy order
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

For a project, I need to extract all the frames of an AVI video. This I have accomplished by with free program. The problem: it took a 30 second clip and spit back 5400 some frames, and the image only changes every 20 frames or so. I really only need about 270 frames, but I didn't want to go through each one manually. So, I wrote a small program using Visual Studio 2008 and VB to open each image in binary and compare it to the one before that. If there is a discrepancy of more than 55000 (to accommodate slight errors in capturing), it leaves the file be. If not, it deletes it.
After much troubleshooting, I got it all to work. I ran it on the directory containing the images, but when it finished, only the first image remained. I checked into it, and found that the FSO loop I have set up to loop through each file was pulling the files in apparently random order. It will give me the image "bg(01).bmp" and then immediately "bg(1362).bmp" and so on. And the order changes every run.
I tried setting up an array to generate a list of all the files and then sort them, so I could pull off the name of the file, then the next one, ect. but it took over 3 hours to finish processing the array, and then It was using a huge chunk of RAM.Is there some way to "force" vb to pull off files in alphabetical order? here is my, code, it belongs with a form. fPath is a global variable, simply pointing to the source directory.

I re-wrote this to make it more readable. If you want to skip right to the chase, look at the ALL CAPS comments in the code blocks. All necessary code has been included for debugging. I've searched multiple forums (including ASP.NET), and the MSDN library and cannot fix this >.<

I work on a vb.net winforms app where we currently are using simple roles for security. We enable/disable specific controls based on if the current user has the required role. We are to the point where this is no longer granular enough.Our application is based on different physical locations we call sites. A user might have permission to do something (for example, edit a site's configuration) at one site but not another. Therefore, we now need to lookup permissions based on current user AND current site. Also, a certain user's permissions may be very specific to themselves ie. no other user's permissions are exactly the same as another user's. Therefore we need a security model that's more permissions based rather than role based.
What's the best way to design a new permissions model that can meet these requirements? I want to make sure that it's easy to implement the checking in the code (I don't want a million if statements sprinkled in our SetUIPermissions methods) and we don't want to have to update every user (400+ and counting) each time we add a new permission. Because of this last requirement I think we need to keep the idea of roles but possibly add/remove exceptions for particular permissions for specific users

I have a dgv with 5 columns (combos) added with the wizard, then in the form constructor i set the datasource, value member, displaymember and datapropertyname for each one, after this i fill the main data table and set the dgv datasource with it.If i just do this and don't use the display index, the columns show in an wired order, doesn't show up like i defined in the wizard neither in the order of the sql statement.
For example, i add this columns (names):
B,C,E
Then if i use this select statement

I have a form containing a datagridview and a groupbox containing 2 radiobuttons.If radiobutton 1 is selected only the order headers are shown.If radiobutton 2 is selected only the orderlines are shown.There also is a button called "show". When clicked the dgv gets filled with data.When I first select radiobutton 2 (orderlines) and I press the show button the columns in the DGV are in the right order (as shown in the code "strview").If I select radiobutton 1 still the columns are in the right order.HOWEVER...when I now select radiobutton 2 the order of the columns get all messed up.

I have a databound Datagridview. The DGV is bound to a datatable of a strongly typed DataSet created using the wizard. Is there any way to re order the columns before displaying them eg: the Columns are displayed in the DGV in this other Col4, Col6, Col3, Col1,Col5, Col2
But I want to it to show as Col1, Col2, col3, Col4, Col5, Col6?
I realise that the display order followed the Column order in the database table and by extension, the datatable. I have re-arranged the columns in the Database but the Datatable still retains the old order.

I am reading a record from a database into a datagridview.I have changed the column "ComputerAwareness" from a textbox column to a combobox column.This column is at the 21st position in the database but after changing it to a combobox in datagridview it is diplayed as the first column in the datagridview.How can I keep the position of this column same as in the database?I have googled a lot for the solution and tried all the possible ways but none seem to work.One of the ways I tried is in the code below.
Private Sub DisplayButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DisplayButton.Click

I'm still trying to get my head around the whole "Lambda Expressions" thing.
Can anyone here give me an example ordering by multiple columns using VB.Net and Linq-to-SQL using a lambda expression?
Here is my existing code, which returns an ordered list using a single-column to order the results:
Return _dbContext.WebCategories.OrderBy(Function(c As WebCategory) c.DisplayOrder).ToList
Note: The WebCategory object has a child WebPage object (based on a foreign key). I'd like to order by WebPage.DisplayOrder first, then by WebCategory.DisplayOrder.
I tried chaining the order bys, like below, and though it compiled and ran, it didn't seem to return the data in the order I wanted.
Return _dbContext.WebCategories.OrderBy(Function(c As WebCategory) c.DisplayOrder).OrderBy(Function(c As WebCategory) c.WebPage.DisplayOrder).ToList

I have an application with various datagrids. I have a specific need for the order of the columns (which I set at design time) but for some reason Visual Studio regularly changes the order of my columns on me when opening the project is VS. So, every time I compile I have to go make sure the columns are still in the correct order. Sometimes they are, sometimes they aren't.
I remember this same behavior in 2002/03 version of Visual Studio with tabs and tab order. If it makes a difference, these datagrids are created at design time with LINQ2SQL Data Sources. I did this all the time with VS2008 and never noticed this behavior.

When user clicks on a button on my form, it sends the datagridview on that form to another class that [basically] does a bunch of stuff and shows a dialog with a print preview. Everything works perfectly fine, except that if a user switches around columns it won't print them in that current order. For example, if user moves the LastName column before FirstName column, then it should print in that order, but it prints in the column order that the datagridview was originally loaded. The dgv1, is the datagridview that was originally loaded, not the current one. [Code]

I have a datagridview that I'm populating from a SProc. The data coms back fine and is presenting in the DGV without any trouble, but I don't like the order the data is being returned in.A long solution might be to modify the SProc to return the data in a different order, but I prefer to handle this on the UI for simplicity. Also, I know the user can re-order but that presents a specific poblem in the way the columns are structured.Is there a way to programmatically change the order at runtime?Here's the ode I have on the UI. If you need to see the adapter class also, please let me know and I'll present it, too.
Code:
Private Sub UpcomingInspections()
AddHandler mAdapter.ErrorOccured, AddressOf HandleDataError

I refreshed my data sources to include additional items from the SQL Server databases and it appears that my entire data source from my VB.NET project disappeared.I am using Entity Framework. I may have clicked on something wrong, not quite sure. Unfortunately I can't recreate the Data Source without creating a new Entity and Data Model.I can delete the entry in the App.Config file and recreated it, however things aren't quite right.Is there a way that I can recreate my Data Source from the entry that is in my App.Config file...since that appears to have remained intact.BTW, I can go to my Data Model and successfully refresh from there, however my project isn't connecting to the database so I have quite a number of errors until I can get reconnected.
