The Database 'DB Name' Is Not Accessible?

Jun 13, 2010

I am getting following error each time I tried to select database. The database 'DB Name' is not accessible. (Microsoft.SqlServer.Express.ObjectExplorer)

Note: My OS is Win Vista.

When I tried to open SQL Mgmt Studio as Run as administrator than I can able to access database properly.

why it is giving error.

I am also getting following error when my asp.net application is trying to access database.

Cannot open database "DBName" requested by the login. The login failed. Login failed for user 'PCNameabcd'.

I am not very good with SQL Server, how to create user and grant them permission in case that is what causing the problem.

Installation :: Intranet Database Application Not Accessible?

Feb 6, 2010

I have created an ASP.NET database application using SQL Server express on one of my home network PC's. I can access SQL Server Express from the other PC's (using SQL Server Authentication) so I know it is set up ok for network access. I can run the web site on the host PC under IIS & everything works ok.

When I try to access the application from another PC using http://192.168.0.8/TestApp/Default.aspx it is not available. I can ping 192.168.0.8 & it is accessible.

why I can not view the web site from another PC on the network?

Dynamic PDF And Accessible Via .net

Feb 5, 2011

I have been doing dynamic PDF creation via ASP.net for some time -- in the form of HTML to PDF conversion. It works well for us, but we have accessibility requirements from the State to make everything is accessible. For static PDFs, we simply "tag" the files manually using Adobe's accessibility tools. Of course this does not work for dynamically created files. PDFs that I create dynamically fail the Acrobat Pro Accessibility test.

want to create PDFs dynamically in ASP.net, but producing PDFs that are tagged and can pass the Adobe Accessiblity test? I have researched many components, but none that I have found support tagging.

I have developed a WCF .NET web service. It has evolved from a console application, hence some shortcuts were taken in VS 2008 rather than establishing the project from scratch as a WCF Web Service.

Web Forms :: Value Of The Textbox Is Accessible During Page_Iniit?

Apr 1, 2010

lets say I have the following code:

[Code]....

So - to start with textbox1.text is set to 1. But - If I do a postback, the value of textbox is lost - it's just empty. I need to pick up the value of the textbox during "DoThis()" but it only works the first time round.

Surely the value of the textbox is accessible during Page_Iniit?

I'm doing somehting stupid here.

(And BTW - I have to call DoThis from page_Init as that method also adds other controls to the page but I need to get this code working first)/

Server Control Not Accessible In Code-behind?

Apr 16, 2013

I have a web page that I am converting from classic ASP to ASP.Net. There are a bunch of "Select" controls (DropDown Boxes) that I am changing to DropDownList controls. I have set the "runat='server'" in all of these controls. However, when I go to the code-behind, they are not visible/accessible. I have tried to "clean" the solution and rebuild it and the controls still won't show.

Make SQL Server 2005 Accessible Via Internet?

Mar 23, 2010

I have an application that runs on a client's server built on a SQL Server 2005 database.We have now developed an ASP.NET v2 application which connects to this database. This web application will be hosted on an ISP's server but needs to access the SQL Server database on the client's server.

The client's server has a firewall and so forth so I assume it should be possible to make the SQL Server accessible via the Internet but of course I am woriied about security. Can someone point me to some best practices to achieve this.

Overload Resolution Failed Because No Accessible DrawImage?

Feb 2, 2011

After looking at about 200 examples on this and other sides, I combined several pieces of code that I found and created one to upload an image, give it a random name, verify that a file with that same names doesn't already exists on the server, resize the image 3 different ways; one keeping aspect ratio and two square thumbnails; and save them to different folders in the server. This is the code:

[Code]....

I'm getting an error on line 95 and 112:

MediumGraphic.DrawImage(Original_Image, MediumRectangle, xm, ym, am, am, GraphicsUnit.Pixel)

I get the error on intellisense: Overload resolution failed because no accessible DrawImage can be called without a narrowing conversion. ..... Argument matching parameter 'srcX' narrows from 'Double' to Inter... narrows from 'Double' to 'Single'.

C# - Controls In A Telerik Control Not Accessible From .cs File?

Oct 28, 2010

I am using telerik controls in my c# asp.net project. I am trying to disable a div in a telerik navigation menu from the .cs file. For example:

if (Emp_Role == "1" || Emp_Role == "5")
{
DivLeave.Visible = true;
}

I try run the project I get this error:

CS0103: The name 'DivLeave' does not exist in the current context

Here is an example of the aspx code

<telerik:RadMenu runat="server" ID="RadMenu1" Skin="Sitefinity" OnClientItemOpened="itemOpened"
Width="670px" Height="26px" EnableShadows="true">
<Items>
<telerik:RadMenuItem Text="Expenses" PostBack="false">
<Items>
<telerik:RadMenuItem CssClass="Stores" Width="640px">
ItemTemplate>
<div id="DivLeave" class="Wrapper">
<h3>
Expense Management</h3>

AJAX :: Image Behind Modal Popup Is Accessible?

Feb 25, 2010

I am using master page, and there is an image on top

<div
id="header"><a
href="http://www.google.com"><img
src="image.jpg"
alt="abc"
style
="border :0px; height :80px;"
/></a></div>

There is content page where I have grid, when I click on it, I am displaying modal popup. Everything works fine. The only problem is: I have close button on top of the modal popup window. If modal displays on top of the image, and if I click on close button, then close button event will not fire, insted it redirect to google.com. All other controls besides image are not accessible. If image is not behind of modal (if I scroll down the page), then close button event works fine.

C# - Particular Information Accessible At Masterpage, Page And Usercontrol?

May 6, 2010

I'm fetching some settings out of the database based on a value passed from a query string. Out of these settings, a few will be used in master page, few on my Page and few in my user control (say login control which is a web user control).I've an entity class MySetting for it and there is a method in my data access layer which returns me an instance of MySetting when I pass the value I got in query string.

I don't want to fetch settings from the database multiple times for one request. I'm using asp.net web forms with C# and sql server.

CodeBehind Class Not Accessible To Code In App_Code Folder?

Jan 31, 2010

I have a PlannerShiftView user control in the root folder of my ASP.NET web site. In my App_Code folder, I have a ShiftViewTemplate class that needs to instantiate a PlannerShiftView (for a TemplateField in a GridView). The problem is, the following code doesn't compile because the PlannerShiftView type is not available in what I deem to be the App_Code 'phantom namespace'.

Please can somebody explain to be what is happening here, as well as what to do. I know I can just move the ShiftViewTemplate out of App_Code, going against convention and without explantion, but that is something of a hollow victory.
