RESTORE cannot process database 'db name' because it is in use by this session.

My issue was I was restoring a database that I also was using as my default database.

So, by changing my user default database to the master db, I was able to restore.

The selected stored procedure returns no columns

The reason was, selecting from a temp table and EF can’t figure out the shape of the results at design time.

The solution for this write this line "SET FMTONLY OFF" in begin part of your Stored Procedure but it will not work in selecting data from another database.
Example : Create procedure SPname

      as

      SET FMTONLY OFF 

ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

I got this when i trying to read a CSV file and trying to get the data in a DataSet using Microsoft Text Driver in your 64 bit machine.

Solution

1. Go to IIS and Application Pools in the left menu.
   
2. Click the project name in the listing.
   
3. Click the Set Application Pool Defaults.
   
4. In General Tab, make the Enable 32 Bit Application entry to "True"

How to Run WAMP Server Parallel with IIS 7 on Windows

When you already have IIS running then you may not be able to run WAMP Server at Localhost. You need to shutdown IIS in order to run WAMP Server properly.

To run WAMP Server parallel with IIS 7, we need to assign port 8080 to WAMP Server so that it runs on http://localhost:8080 and IIS 7 runs on http://localhost

To do this, click on WAMP Server icon on taskbar and go to Apache > httpd.conf
httpd.conf file will be opened. Change ‘Listen 80’ to ‘Listen 8080’ (As shown in the screenshot). Save and restart WAMP.

Now you can access WAMP Server access on http://localhost:8080
And at http://localhost IIS 7 will be running.

5.Go to the properties of the c:\inetpub\wwwroot\dotnetnuke\ folder, click on the Security tab, be sure to add the permissions for the appropriate user (WinXp/2000 uses the local ASPNET account, Win2003/Vista/2008/7 use the local Network Service account). Give this account modify permissions on the folder
6.Open up the the web server IIS Console, start->run->INETMGR
7.Expand the websites node
8.Expand the default website node
9.Right click on the dotnetnuke folder under the default website, click on Convert to Application, if you don't have that option, choose properties and then add the application.
10.Open up SQL Management Studio (2005/2008), or Enterprise Manager (2000)

1. If you have only one instance of SQL running on your server, and you intend on using the SQL instance on your machine, you can enter a '.' for the database location or use (local) as the local instance name (the brackets are necessary(. Otherwise, if you have more than one instance of SQL running on your localhost (SQL2005, SQL2008Express, SQL2008) and you are going to use one of the local instances enter a period followed by a slash and the instance name. For example '.\SQL2008'

1. Integrated Security (no changes)
2. Not using Integrated Security

How to add new tables to NOPCommerce

I spent plenty of time for delving into this problem' depths. I can summarize the solution as follows:

1. Create The Entity Class (e.g Entity.cs)

Path : Nop/Core/Domain/Entity.cs

2. Create The Mapping Class (e.g EntityMap.cs)

Path : Nop/Data/Mapping/EntityMap.cs

3. Create a Model for MVC (e.g EntityModel.cs)

Path : Nop/Admin/Models/EntityModel.cs OR Nop/Web/Models/EntityModel.cs

4. Create a validator for model (e.g EntityValidator.cs)

Path : Nop/Admin/Validators/EntityValidator.cs OR Nop/Web/Validators/EntityValidator.cs

5. Create A Mapping Configuration On AutoMapperStartupTask.cs for Entity and Model

Path : Nop/Admin/Infrastructure OR Nop/Web/Infrastructure

6. Apply Mapping between Model and Entity on MappingExtensions.cs

Path : Nop/Admin OR Nop/Web

7. Create a service class and service interface (e.g EntityService.cs , IEntityService.cs)

Path : Nop/Services/EntityService.cs AND Nop/Services/IEntityService.cs

8. Update DependencyRegistrar.cs

9. Finally Create Controller and View for given model

Cannot implicitly convert type 'int?' to 'int'. An explicit conversion exists (are you missing a cast?)

I got this when i use linq query
query is below
public IQueryable<GasUtilGas> LoadAllForkliftGasUtilByDetailId(int id)
        {
            var res = from gu in db.tblForlkliftGasUtils
                      join g in db.tblGas on gu.GasID equals g.GasID
                      select new GasUtilGas { GasNo = g.GasNumber};
            return res;
        }

It seems like g.GasNumber is a nullable int field in the database.  Change the model to this:
public class GasUtilGas
    {
        public int? GasNo { get; set; }   
    }

The data source does not support server-side data paging

You can't use an IQueryable object to data bind to a GridView and still use Paging and Sorting. You must return a List to the GridView using the ToList() method. Thanks

My latest issue was how to integrate CKFinder for image upload in CKEditor. Here the solution.

1. Download CKEditor and extract in your web folder root.

3. Then add references to the CKEditor, CKFinder and put
 <CKEditor:CKEditorControl ID="CKEditorControl1" runat="server"></CKEditor:CKEditorControl>
 to your aspx page.

4. In code behind page OnLoad event add this code snippet

protected override void OnLoad(EventArgs e)
{
CKFinder.FileBrowser _FileBrowser = new CKFinder.FileBrowser();
_FileBrowser.BasePath = "ckeditor/ckfinder/";
_FileBrowser.SetupCKEditor(CKEditorControl1);
}

5. Edit Confic.ascx file.

public override bool CheckAuthentication()
{
return true;
}

// Perform additional checks for image files.
SecureImageUploads = true;
