VS 2010 What Would Make Something Fail In IDE That Is Already In Production
Mar 7, 2013
What would make something fail in the IDE that is already in production?
I loaded just the aspx file into Visual Studio. it is just the file. It is used as a template on a CMS system (don't ask). The point is that I know that the paths work. So why does it fail in Visual Studio when I try to run it?
I have some asp.net code with a visual basic back end code file. It loads all the associated files located on the server that the aspx file mentions. But when I load the aspx file in Visual studio it says that a mentioned master page file cannot be loaded.
I started the Bakery site demo...everything runs fine on my local machine.When I publish the site to production server in w2k8r2+iis7.5 and with .net 4.0 (integrate) pool, my bakery apps not able to connect to the .sdf file.
Error I got is :
Connection string "bakery" was not found. Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code. Exception Details: System.InvalidOperationException: Connection string "bakery" was not found.
Source Error:
Line 2: Layout = "_SiteLayout.cshtml";
Line 3:
Line 4: FacebookSocialPlugins.Initialize("[xxx]", "[xxx]","bakery");
In my development environment, my CSS loads perfectly. But when I publish the files to the server, the CSS no longer loads.
Originally, when I had this problem, it was because I was denying access to unknown users for all directories. It was also occurring in both environments.
When I fixed that, the CSS started working just fine. But when I publish it to the server, it no longer works.
The website appears to function. I can log in, navigate pages and everything. It's just that the CSS doesn't work.
I checked the permission on the directory and it has access to NETWORK SERVICE, the admin account and IIS_IUSRS.
When I start a new ASP.NET project in Visual Studio 2010, I can either create a new ASP.NET Web Site or an ASP.NET Web Application. What's the difference between these two project types? Why would I choose one over the other?
note: this question is an exact duplicate of this one, but I'm asking specifically about Visual Studio 2010 (there are no answers targeted at VS 2010 in the original question). So are the answers of the other question still valid or are there any changes with VS2010 which results in different answers?
I am currently using Visual Web Developer and have a website with 2 pages which are "Tables.aspx" and Variables.aspx". I was wondering if their is a way to make a specific cell in a gridview clickable/as a hyperlink so that it would take the user to another page and display the required information in another gridview based on what Table Name from the gridview has been clicked on?
The gridview on the "Tables.aspx" page has 5 fields and they are Table ID, Table Name, Table Description, Source and Record Count. The field that I want to make as a hyperlink is the Table Name field and when clicked upon I would like all the relevant information (Table Name, Variable Name, Variable Description) for this field to appear in a gridview in the "Variables.aspx" page. The database table names that would be required are "variables" and "tables". In order to do this would I have to create/run some sort of SELECT command in behind the source tab for the gridview?
NB table name comes from tables database table and variable name and variable description comes from the variables database table.
Is there a way to make a new project file using Visual Studio express 2010 using the files downloaded off a server from an asp.net web site? If so what are the steps? I would like to make a new project out of the old files without starting from scratch, I don't want to just edit a couple of things I would like to create a project file using the files I can get off the server if possible. It would be C#.
I have Oracle 10G express edition. I have configured it on windows 7 system. Now I want to make a 64 bit application using visual studio 2010 and connect to oracle 10 g server. If I run my application in VS2010 explecitly in 86 mode then I am connected to database but I want it to happen for 64 bit
Everytime I try to create a new sql 2005 server project I get this error. Then after I hit ok VS 2010 crashes.
Could not load file or assembly 'System.Data.SqlServerCe, Version 3.5.1.0, Culture=neutrail, PublicKeyToke=89845dcd908080cc91' or one of it dependencies. The system cannot find the file specified
I like the way that the chart control seems to automatically determine the X axis range for me based on the data, but in this case, the data can only be whole numbers.
What is the easiest way to specify whole numbers for this axis?
I want to make my visualwebpart to communicate with other webparts like (Provider and Consumer) I am thinking can I make my VisualWebPart which has a ascx file which is drived from UserControl, can I make it a Provider or a Consumer. I am adding these webparts on Sharepoint 2010 webpartpage.
Using the code such as found below, sometimes certain .PNG files will fail to load. While other images, nearly identical in size, never have any such problem. Build Action set to Resource. Why is that? Anybody figure it out? This is for a datagrid but I doubt the control has much to do with it. Probably certain .png files make Visual Studio 2008 choke because of some attribute set internally. But it's a mystery to me....anybody else notice this? # private void dGrid_LoadingRow(object sender, DataGridRowEventArgs e) { Employee emp = e.Row.DataContext as Employee; FrameworkElement ele = dGrid.Columns[4].GetCellContent(e.Row); string url ="http://localhost:7642/DisplayImageHandler.ashx?id=" + emp.ID; Uri imageUri = new Uri(url, UriKind.RelativeOrAbsolute); (ele as Image).Source = new BitmapImage(imageUri); } private void img1_ImageFailed(object sender, ExceptionRoutedEventArgs e) { Image img = sender as Image; // Display an image for error here }
I have a PageMethod that works perfectly well when it either (a) running in the VS dev server, or (b) deployed but marked with UseHttpGet=false.
What doesn't work, and is driving me mad, is having UseHttpGet=true and then deploying it to a test server (Vista & IIS7). It fails to call through the proxy with error code 404 coming back. But it works find if I set UseHttpGet=false.
I have gone through all of the basic stuff I can think to check, and as noted it works perfectly well on the dev box. So there must be something particular about full-blown IIS7 and its config that I am missing..
anything to check in the IIS manager that would cause this to fail? I've tried with forms authentication enabled and disabled, as a few posts mentioned issues with that.
I am working on my first project with Linq to Sql entities/winforms, and I have little problems updating the entities childs in the main form, when I come back from the entity editor....
I have a list of people, and I can edit them or add new. The edited or new person opens in a new form and can have many addresses that can be added modified from the person editor and it opens a third form...
when I have finished edit the new address, so i return to the person editor and add the address, within the person entity context... so person.address.add(newAddress)...
Then I update the list of addresses, referencing: Datasource= foreach(address adr in person.addresses).And when I have finished editing the person i return to the mainform and save the changes from that entity.
_datacontext.save()
The problems I have are that if there is a new person, and I don't add addresses, the person saves without problem. But It doesn't do it if I add any address. With the updates I haven't any problem, they updates all, adds new addresses, but I can't remove anything with the person.addresses.remove(address)...
I have a problem when user changes the password using the Account Membership implementation from ASP.NET MVC.
I'm creating users from ASP.NET Configuration tool at Visual Studio. Thats works fine. But when my users changes password using the published site, the login process fail, when try to authenticate using new or old password, either.
Have any workaround that I'm forgot to implemento to avoid this?
We are developing an ASP.NET eterprise level application. Customer wants to support for load balancing and fail over. Also customer need that if one server pc fails, end user should not notice that. is this possible? Will there be a timeout for the end user?
I have reasonable experience programming for windows form programs in VB 2005, but I am new in ASP.NET. I have tried the file system website, and it does not seems to have a problem for me. However, when I was trying to create a website to run with IIS, it failed. This is what happened, to start, I chose location:HTTP on the "new web site" dialog box, and using browse button, I opened the "choose location" dialogbox. I choose "Local IIS" on the lefthand side. Then, I create new virtual directory, with the alias name "Test" and folder c:my documentweb site st (new and empty directory). Then I clicked the open button, it was still fine, where it returned to the "new web site" dialog box. However, when I clicked the OK button on the "New Web Site" dialog box, it comes up with this error:
"Configuring web site 'http://localhost/Test' to ASP.NET 2.0 failed. You may need to manually configure this site for ASP.NET 2.0 in order for your site to run correctly"
When I clicked OK, it does come up with a blank website, however if I run it, it will comes up with this error:
"Unable to start debugging on the web server. The server does not support debugging of ASP.NET and ATL Server application. Click Help for more information on how to enable debugging" but there is no Help button!
By the way, all the trials are done in VB2005/ASP.NET 2.0, we are trying to upgrade to VB2010 sometimes next year. The computer is running Windows XP.
I've received 5 error reports from a site overnight. XML Code: Exception information: Exception type: System.Data.SqlClient.SqlException
Exception message: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
It would seem that it's an issue with the server but it was reported to always occur at DomainModel.Services.ConfigService.get_companyName() which occurs when my config service asks the database for the company name using ByName("Company_Name")
Is it just a server glitch or am I going to have to do some debugging today? I can't get it to fail no matter what I try.
edit - I just noticed one of the error reports was from a separate site. The first 4 were a local IP (ugh, probably the site owner) on one site between 11:00-11:04pm while the other was a chinese IP on my site at 11:07.
My masterpage has a loginStatus control to let users log out and it works very well on normal pages .Recently, I created a new content page associated with the mentioned master page. Such new page allows users to add textboxes dynamically through ajax asycpostback. Unfortunately, loginstatus right now fails to work when i click it. I traced the process and i found out that the loggingout event was not fired when i click it.
I follow this video to make such "Dynamically add control" page.
I have several models that implement a array property using null object pattern in the following manner:
[Code]....
The problem is that any time I attempt to bind to a property of this type the DefaultModelBinder.CollectionHelpers.ReplaceCollectionImpl method wants to call ICollection<T>.Clear() and then ICollection<T>.Add() on the zero length array.
The real issue seems to be in DefaultModelBinder.BindComplexModel() method however. The method contains an explicit check for arrays and special handling to account for the fact that they don't support clear/add functionality. The problem is that the check stipulates that the array model must also be null. If it is non-null, normal ICollection<T> handling ensues which presumes support for clear and add. Can any one explain why the null check is there? It seems to me that either 1) the null check should be removed to permit replacement based binding to non-null arrays or 2) an explicit error stating that non-null arrays are not supported should be thrown.
I vote for the former. I can understand that in general, replacing an existing model with a refrence to a different model would be considered a bad thing. The calling code would not expect this in general and it could lead to hard to find bugs. However, in the case of arrays, if the calling code expects the array property to be modified at all, then I think the normal expectation would be that such modification would occur via replacement of the array.
