I am just starting to look at .NET 4.0 and Entity Framework 4 and having trouble finding the best way to achieve something. I'll explain with a quick example:I got my CategoryManager class that looks like this:

I want a piece of code for asp.net 3.5 using visual basic. and i am using MS access database.
I have two three text boxes and 2 image upload controls and a submit button.
I want a piece of code in which a user can upload images and store it in our database . i want an asp.net visual basic working code. also i need query behind the submit button.
I want to create a search button and put the results in a data grid.

I just made my first MVC3 app, and I thought it would be fun to upload it to my web hotell. So I did a publish locally in visual studio and then transfered the published files to them over ftp. They have support for MVC3, so there shouldn't be any problems there. But what I get when I try to go the the page I get an 403 - Forbidden: Access is denied
I've tried to add the:
<authorization>
<allow users="*"/>
<deny users="?"/>
</authorization>
I am trying to figure out what are the basic assemblies required to run a basic ASP.NET 4.0 website. Say.. a website with just a label in it. I looked online and didn't find a list there. I know installing the framework 4.0 will give me all the dlls but I just need the basic ones that will make a basic site work on ASP.NET 4.0.
View 1 RepliesThis could be very straight forward for some of you, but I got caught up. I am doing very simple test - browsing from IIS Manager to see the default page or "under Construction", however I am being challenged to provide my login credential . When I provide my login credential, I am able to see the default page. I wanted to see the default page without providing my credential since Enable anoymous access + basic authentication I am simply wanted to see the default page asit is working on other servers except this one. I have included screen print to make sure may question is clear.

View 1 RepliesIn regular asp net I can run (debug) the application but I can either "view in browser" that gives me the option to view the application and write code on same time.In MVC I can't find this option.What is the basic DATA MODEL for working with SQL DB.I mean with no any framework (entity framework, Sub sonic, Link to SQL etc')
I look for basic application that works with data but with no fw.What is the popular DB framework that working with data. I am looking on mvc series Like

I am using the ASP.NET3.5 gridview control in a new project. My problem is that the gridview presents data in basic tabular format, whereas I want a grid with row header / grouping behaviors. An example of this would be Outlook web interface, which can group emails by date, as well as allowing you to select individual emails to display.
My problem: I can't see how this could be easily done with Gridview? I did find a product called Telerik that has a seemingly fancy Gridview, but I am hesitant to spend money on a single components that now also locks me into a third-party framework...
I am very new to thegridview control. As while searching for sample coding to edit the Gridview datas during runtime,i got the following codings protected void Edit(object sender, GridViewEditEventArgs e)
View 4 RepliesIs there a way to delete an entire gridview with code? I have a gridview that is created based on a value is selected in another gridview, and the bound columns keep being created on top of the previously created gridview. I would like to completely delete it and create it anew based on the new selection.
View 4 RepliesFor my Dynamic Data site I have a table that has a join to a number of other tables. If I use the standard page for this table I get all of my columns from the primary table and related tables (which is good) and the appropriate literal values from the related table (which is great). The bad part is the order of the columns.
To address the order of the columns I created Custom Folder/Page for the table. I also have a partial class that controls date formatting. This takes care of the ordering of columns fine (which is a step forwared), but now I'm seeing the foreign key IDs instead of the literal values from related tables (which is a step backward).
All I did was copy the standard page to the Custom folder for the table, turn off AutoGenerateColumns, and specify the column order and display name. Why would the foreign key change occur? As a side note, if addressing column order in the partial class is the preferred method I could go that route, but I haven't been able to understand how to do that in VB (I've seen many examples in C#, but that's not my strong point).
I'm trying to pass a value (address) from a listview control using visual basic to a google map address control on the page load event. Here is the code I have so far in vb:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'Pass address from Listview to Googlemap address
GoogleMap1.Address = ???
GoogleMap1.Zoom = "14"
GoogleMap1.ShowScaleControl = True
GoogleMap1.EnableInfoWindow = True

I use a DetailsView control to insert some basic contacts data. If I use ampersand "&" in any of the string fields it is inserted into the database as "&". why? Does it have to do with html encoding "at_inserting" event?
View 7 RepliesI try to use the ADO.net to retrive the basic data in details view or gride view of logged In person using 3-tire architecher. I don't want to use LINQ.

and basic information. after login user while click on the basic information page he will able to see his details only. do i need to bound the details in DLL class file if it is so giude me through sample page coding or or we can join the remote support using team viewer so you can guide me from the web also.
I've been out of the ASP.Net arena since 1.1, and I'm starting to get back into it after a hiatus.
In the past, I would generally create SqlDataReaders, wire them up to pull from tables in a database via direct sql or accessing database views (mostly in MSSQL), grab the data, and display it in some datatable, or datalist.
Modifying data would usually be calling a stored procedure in the database to add/modify data, and then retrieve it afterward.
Now that I read up, I see there are alot of new things in ADO.Net world; strongly typed datasets, auto-generated adapters, etc.
My question is, does anyone have a good reference on best practices (or a book recommendation) on how to handle data access, and data manipulation and display now? I'm assuming that there are more automatic ways to show and manipulate data than before, but the new details are quite vast (which is good), but slightly overwhelming for me.
I'm using a basic date picker control in a gridview and using an sqldatasource, I don't get an error but the date selected is not saved only null is saved. why that might happen or make any suggestions on what I might try to correct this?

View 7 RepliesHere's a short explanation of my asp.net project.
1) the default page loads, it will read the Windows Login of the user opening the page.
2) I'll check if this login exists in a table stored on the webserver.
In this Access Database, there's a 2nd linked table, pointing to another access table on a network location. Now, I want to read data from this linked table. However, at this moment I receive an error:
"The Microsoft Jet database engine cannot open the file '\<ip><shared-folder>statistics.mdb'. It is already opened exclusively by another user, or you need permission to view its data".
Some extra info:
- The network folder has read and write permissions for everyone
- the user and group permissions on both access files are set to read/modify/administer for the Admin user (on the tables I want to read from)
- IIS authentication on the server is set to "Windows Authentication" (this is needed so I can read the Windows Login from the user). All other authentication modes are disables (like anonymous, ...)
- When the error occurs, no other program or process has access to the statistics.mdb (so, it can't be locked by someone else)
- the web.config files access connection string looks like:
<add name="AccessConnectionString" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\<IP><shared-folder>statistics.mdb;User Id=admin; Password=;" />
Like I said before, in this statistics.mdb file, there are 2 tables. One normal table, and another linked table (pointing to a network location)
Searching for solutions, I discovered the following:
- if I don't use linked tables, everything works fine (however, I have to use this linked table)
- even if I connect directly to the table in the network I receive the error. So, I'm pretty sure I don't have sufficient rights to read from this table.
I read that not the Admin user is opening the file, but actually a user called ASP.NET. This user doesn't have the correct rights to do this. However, I'm not sure if this is true.
I made a project to use the access membership provider from [URL] and it works. But I need to edit my database but when I configure my database, I cannot see the tabel, I can only see the queries in mdb file. when I select the field from query, I am unable to update it. My code is as follows:
[Code]....
I have a data type mismatch while inserting into a number field in an access database using a parameterized query.I think this should be pretty simple but I am still learning a lot.
[Code]....
I have some commented out as I am working one field at a time. The working fields are textboxes and the non working ones are dropdown lists. But I think it may be the field that the list is drawing from? Not sure.
I have one question here.I created a registration form using asp.net and c#.
when I entered all the fields in that form and hit the register button the data will be inserted in to the database table called xyz table
in that table I have an id field which is a text field in access database consists of guid starting with letter P
when I inserting the data from aspx form...the guid is not inserting into the table.
one of my datarecord in that table with the id field is like this.(.P11111111-1BBB-4444-A9D1-111111111111)
need to insert anoother record in that table that field must be generate with the ID starting with P..its an guid.. the creating guid in the aspx.cs page..??
I have a form wilh couple of Drop downs and text boxes and a Data Grid View which displays data from Access Table. When I hit add button on the form, I can see the data being added to the Grid View. But when I close the form and open the Access Database File (.mdb), the respective table is empty. The Access Table is not being updated. Second time if I open the form, the Grid View is also empty.I am pasting my code here.
