I have added a Report Viewer Control to an aspx page in design view. If I click on the Smart Tag and select "Design a New Report", the Report Wizard starts and immediately displays the error:
The root element of a W3C XML Schema should be <schema> and its namespace should be 'http://www.w3.org/2001/XMLSchema'.
I have Binged and Googled for similar problems to no avail.
Any thoughts on where I have gone awry?
Using VS2010, AspNet, C#, SQLServer2008
In ReportView web application, I want to display only the export to PDF option.
not display Word, Excel!
how to do?
I'm using Visual Web Designer 2010, VB. I'm trying to create a routing whereby I can read an Excel file, manipulate the data (by adding additional columns and information) and output it back to Excel. I found the routine (a starting point) below on the web but cannot get it to work. The first thing I did was to create an empty table in the SQL database named ExtendedBOM. The problem is now with Button3, the "For Each dr AS DataRow In ds1.Tables(0).Rows" , I get the message: "Cannot find Table 0." and I'm at a complete loss as to what the problem is. Does anybody have any suggestions what I can try next? The spreadsheet I'm trying to read in has 5 columns (Item, Quantity, Part_Number, Reference_Designators, Description) and the first line contains the header text. Thanks!

Visual Studio has the option when doing a web deploy to "Execute Code First Migrations (runs on application_start)". When you select that check box, Visual Studio configures the destination web site so that Entity Framework automatically deploys the database or updates it by running the MigrateDatabaseToLatestVersion initializer on application start, as explained in this VS web deployment tutorial.
My question is... How does it configure the site so Entity Framework automatically deploys the database or updates. What is Visual Studio actually doing to the publish to accomplish this?
Dear All,
i have problem when i set identity in web config file like this <identity impersonate="true" userName="userName" password="password" />
intellisense not work in my project ,i am using VS 2013.
can any one help me?
thanks.
I have just completed my first ASP.Net Web application and I need a walk through to use the One-Click deployment to get my application on the server.
Also, when the application is deployed to the server do that mean it will run on the server and do not need any resources on the users PC.
I ask the question because a version of the same application is running on windows on a PC but it can not run on Windows XP because xp does not support certain resources (Framwork 4) etc.
When it is running on the server will the application be able to be access my a pc with XP and still execute OK?
Greetings and Salutations,
I have installed VS 2012. it is slower then molasses in winter. BUT that is not my real issues. After install - one: my vs 2005 has been wiped and only BI studio is left, Two: when I try to debug in vs 08, 10, or '12 I get no errors but no web pages is display unless I click on the root url in the app dev server box that opens when you click on the app dev icon in system tray.
I guess I can re-install vs '05 but how do I get vs to open my web pages in the debugger?
Any advice is appreciated and many thanks for taking time to review my quesion.

Migrated from VS2010 to vs2013, compiled any application and it worked, but when run command gives the following message below:
--------------------------

The Debugger Resource DLL is out of date. If this problem persists, use 'Add or Remove Programs' in Control Panel to repair your Visual Studio installation.

Accessing the site administration tool in visual studio 2013?
I need to create user and functions, I want to configure security! I do not know where is the tool in VS2013.
I'm using Visual Web Designer 2010, VB. I would like to know if there is a way to export selected Sql tables (approximately 13) to Excel, placing them all in the same spreadsheet but placing each table on a separate Excel (2003) worksheet? Can this be done with one single command (I hope) or would it be necessary for a separate command for each table? I'm a newbie and this is above my level at this point. Thanks!
Hi,
I have developed one asp.net application with MVC 5 and I used couple of javascript framework like
Application is running fine when I run from VS2013 on IE & Chrome.
But After I publish my application on web server and if I try to access my application from different computer or client I am facing below errors on Internet Explorer 11 only. I am not facing any error on Chrome of any versions.
But if I try to access my published application from server itself with http://localhost:<port>/ then everything works fine but if I try to access withhttp://<computername>:<port> problem will continue.
Note: I have updated my IE with latest version.
I'm running the free version of TFS via visual studio .com and was wondering if there's a way in VS 2013 to never let it check in web.config. Probably a TFS question but I didn't know where else to post. I did some searching but couldn't find anything that worked.

Hello Everyone
The above code is for my email sending function.
This works perfectly fine.
But as you can see in the from field is Hard coded. (see below again)
.Subject = Me.Subject .Body = Me.Body .From = New MailAddress("noreply@portals.mypbiz.com", "Careers portal") AddAddressString(Me.MailFrom, .ReplyToList) .Sender = New MailAddress("noreply@portals.mypbiz.com", "Careers portal") AddAddressString(Me.MailTo, .To) AddAddressString(Me.MailCC, .CC) AddAddressString(Me.MailBCC, .Bcc) .IsBodyHtml = True
But I want to change it. In my front end there is text box to provide the email address for from field , To field , CC and BCC. But as the from field is hard coded the email always comes from noreply@portal.mypbiz.com
how can I fix it so that the email will be sent from the email address provided by the user in front end.
I have changed hard coded line and tried the following code .but then i don't receive any email i.e the email sending doesn't work.
With Message .Subject = Me.Subject .Body = Me.Body .From = New MailAddress(Me.MailFrom, "Careers portal") AddAddressString(Me.MailFrom, .ReplyToList) .Sender = New MailAddress(Me.MailFrom, "Careers portal") AddAddressString(Me.MailTo, .To) AddAddressString(Me.MailCC, .CC) AddAddressString(Me.MailBCC, .Bcc)
Though I can see that Me.Mail From contains the email address provided in the front end field when I debug the code.
But No email is received and I get the following error with the changed code.
Server Error in '/' Application.
<div align="center">The specified string is not in the form required for an e-mail address.

It is said that with visual studio, perhaps with web essential as well? the web developer can review the html page in the browser during debug/preview? then update the html content in the review page, then the html content updates can be saved to the original html page in visual studo?
How to find the feature and enable it? I tried it with my visual studio 2013 update4, seems it didn't work. if you have the instruction/steps, it is greatly appreciated.

I'm using VSE 2012 Express. VB code placed in class modules have expand/collapse icons ( small box with + or -) which are very helpful.
These icons also show up in the HTML body of .aspx pages, but not in the server script included in these pages.
Is there a setting or option to have those icons show up in server script included in .aspx pages?
Thanks
I know I used to have one back in the days of "classic" VB. It might have been part of a plugin to the IDE.
In the code editor you could put the cursor inside a function or procedure and click this toolbar button and it would pop up a list of all the places in your code that called the thing your cursor was in. Very useful when you have a lot of code.
I can't find it in VS2013.
Does it exist?
I have recently upsized a MS Access database to SQL Server 2008 using the upsizing wizard. Now I want to begin designing my Data Access Layer. I am following a set of tutorials located here as the basis for my design: http://www.asp.net/web-forms/overview/data-access/introduction/creating-a-data-access-layer-vb I am using Visual Studio .Net 2010 and the SQL Server database is 2008. I realize that these tutorials were written for VS 2005 but I have used them successfully with other versions of Visual Studio. I'm not sure what is happening here and I would appreciate any assistance you can provide.
I have created the web site project and added both the App_Data and App_Code folders to my project. I have put a copy of my SQL Server database files into the App_Data folder. Server Explorer shows a successful connection to the database. However when I add a Typed DataSet to my project events do not proceed as they should according to the tutorial. I am prompted to move the Dataset into the App_Code folder and I respond Yes, but the TableAdapter Configuration Wizard does not start as the tutorial says it should, nor as I remember it should from my past experince. I'm not sure what is happening here and I would appreciate any help you can provide.
