Do you have experience that after you have successfully published your application but the target folder is empty?

1. Click "Publish Web Site", enter "Target Location", and click OK
2. Site builds successfully
3. files in destination directory are deleted

ASP.NET Cookies is domain dependent

Cookies is Domain dependent. Cookies created under subdomain beta.mydomain.com will not able to retrive when access to www.mydomain.com. To ensure that we can retrive the same cookies, we need to specify the domain
For example, we want to write the information to cookies under mydomain when we access to url beta.mydomain.com

HttpCookie cook = new HttpCookie("mydomain");
Response.Cookies.Clear();
Response.Cookies.Add(cook);
cook["UserId"] = userId;
cook["Name"] = username.Text;
cook.Expires = DateTime.MaxValue;
Response.Cookies.Add(cook);
To retrive the cookies information:

if (Request.Cookies["mydomain"] != null)
{
if (Request.Cookies["mydomain"]["UserId"] != null && Request.Cookies["mydomain"]["Name"] != null)
{
Session["UserId"] = Convert.ToInt32(Request.Cookies["mydomain"]["UserId"].ToString());
Session["UserName"] = Request.Cookies["mydomain"]["Name"].ToString();
}
}

If err.number <> 0 then
If document.all.RadDynamic.checked Then
strLogoID = strLogoID & "," & document.all.RadDynamic.value
End If
Else

After some antivirus activities, my partner development machine face issue above.

This may due to some permission setting in Temp folder. To solve it,

1. Go to %Systemroot%, normally C:\WINDOWS or C:\WINNT
2. Right-click the Temporary folder (mine is C:\WINDOWS\Temp) and select Sharing and Security. Select the Security tab and take a look at the list of “Group or user names:”
3. NETWORK SERVICE should be in the list. If it is not, click Add and type Network Service in the text box:

4. Make sure NETWORK SERVICE have Full Control in the Permissions list.

5. Click OK.

6. Restart IIS (Run iisreset)

Test on the web, and it solved.

If you still have the same problem, please check whether you are using McAfee antivirus. If yes, it's probably cause by the access protected properties setting in mcAfee antivirus. Please make sure you unchecked "Prevent execution of scripts from the Temps folder" in "Access Protection Properties"

To do so, right click on McAfee icon in Taskbar and Click on "VirusScan Console..."

Double click on "Access Protection" and a new "Access Protection Properties" window will pop out. Make sure you unchecked "Prevent execution of scripts from the Temps folder" under Block column. Click OK to close all the window.

Problem should be solved.

Create failed for Login 'xxx'. (Microsoft.SqlServer.Express.Smo)

I was trying to create a user with weak Login Name and password. Error message below shown.

Create failed for Login 'xxx'. (Microsoft.SqlServer.Express.Smo)
ADDITIONAL INFORMATION:
An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.Express.ConnectionInfo)

The MUST_CHANGE option is not supported by this version of Microsoft Windows. (Microsoft SQL Server, Error: 15195)





What i do is uncheck the "Enforce password policy" when create the new user. This way you will not get the error message, but this is not the recommended way for the production Login Name and Password.





Problem solved.
