I got a hard time with the Image.FromStream method in my website. The code below works perfect on my computer. But when I uploaded it to the test server, it always gives me "Parameter not valid" exception.
if (!afuImageFile.IsUploading && afuImageFile.HasFile) { System.Drawing.Image imgFile = System.Drawing.Image.FromStream(afuImageFile.FileContent); }
the afuImageFile is an AsynFileUploader control in Ajax Tool Kits. afuImageFile.FileContent is a HttpInputStream.
I tried to install Visual Studio Prof 2010 trail version in my system, but i got an error saying 'Please remove/uninstall Visual Studio 2010 load test controller' to proceed installation. i uninstalled my previous VS2008 software from system and i could not find anything like 'Remove/Uninstall Visual Studio 2010 load test controller' software in my Add/Remove Programs.
I am trying to configure one http module(a vb module) on MOSS site. In this module I have entry like below:
Dim roles As String() = Nothing Dim webIdentity As New GenericIdentity(OracleUser, "Form") Dim principal As New GenericPrincipal(webIdentity, roles) HttpContext.Current.User = principal System.Web.Security.FormsAuthentication.RedirectFromLoginPage(HttpContext.Current.User.Identity.Name.ToString, False) Due to this I am getting 500 internal server and exception on browser is: Exception of type 'System.ArgumentException' was thrown. Parameter name: encodedValue
If I comment "HttpContext.Current.User" related two lines then it redirect to form login.
I need to make a windows application and the requirements is like this: Data is to be entered through one form and those values are to be displayed in a form in different computer.should i use in order to get this done. My main concern is to efficiently transfer the data.
Is there a good way to test and debug these errors. I constantly get them emailed to me from my production site but I can not duplicate them. Below is the entire error.

In the codes below, I got an error on the 2nd line. The "Connection" string is defined in Web.Config.
What does the Exception Details mean? How to solve the error?
Dim strConn As String = ConfigurationManager.ConnectionStrings("Connection").ConnectionString Dim conn As New SqlConnection("strConn") Dim queryString As String = "SELECT CustomerID, CompanyName FROM dbo.Customers" Dim adapter As SqlDataAdapter = New SqlDataAdapter(queryString, conn) Dim customers As DataSet = New DataSet adapter.Fill(customers, "Customers")
Exception Details: System.ArgumentException: Format of the initialization string does not conform to specification starting at index 0.
Background: I use SQL server 2005 developer edition and visual studio 2008. Visual studio 2008 is running on a local machine with Vista business edition. SQL server is running on a remote server using Windows server 2003. Both computers are within the same domain.
Problem: First, I used the server explorer to connect to the SQL server. Everything works as desired. Then I write code to do the same thing. I keep getting the following error 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: SQL Network Interfaces, error: 25 - Connection string is not valid)
However, I used the exactly identical connection string as the one used in the server explorer. So connection string should not be the problem. In addition, I tried the test code in MSDN, which tells whether my domainusername can flow the network. It turns out the user name is fine. I also went to the SQL server management studio and found the login for my computer is NVCWeihao while my computer login name is NVCweihao. I am wondering if this uppercase letter really affects the connection.
I have built visual basic windows forms application with Visual Studio 2010. I want to be able to create a report with a yes/no parameter that show either a detail list or a summary only.I built such a report with a windows form and reportviewer.I used View Report Data in the report design mde to create a "ShowAll" parameter but I am now unable to provide this parameter at runtime because the reportviewer does not prompt for a parameter. I found no visual basic code to set "ShowAll" parameter from a report form checkbox placed on the report form to the reportviewer.
I'm sure but for an individual at home writing web sites I assume I just want Visual Studio 2010 beta 2 and NOT team foundation server, right? What are the minimum system requirements to run this (no doubt beast)? I have a Lenovo laptop running ultimate Vista - and the hardware is Duo Core 2.5 Ghz, and 4 gig of Ram, is that enough of a machine? Last, I own VS 2005, how does the licensing work for 2010, do I pay now, later, what?
I want to get only the current date and not time in asp.net( visual studio 2008). But in 2008 we have the properties associated with time like System.DateTime. How to calulate only system date?
I am looking to add a browse button to a visual studio app something simular to the the dialog box in the 'fileupload' tool. I am looking to be able to graphically select any file from my computer or a computer across a network.
In some of my new websites under .NET 4.0 my Visual Studio does not recognize System.Linq as a valid class. I need to add a reference to System.Core in Web.Config to solve this but there are projects where this is not needed.
I had something happen with my pc and had to do a system restore. This has caused some of the files in my project to be deleted. Is there a way to recover these files?
Is there anything I can do to prevent files from being deleted in the future if I ever have to do a restore again?
My web site used ASP.NET 3.5 SP1, MVC 2, and EF. Last night I tried to upgrade to ASP.NET 4 (& EF4) under VS2010.
If my views are compiled (MvcBuildViews property is true), then the build fails with this error message: Error 5 Could not load type 'System.Data.Entity.Design.AspNet.EntityDesignerBuildProvider'. C:WindowsMicrosoft.NETFrameworkv4.0.30319Configweb.config 129
It's actually complaining about my system web.config file.
If MvcBuildViews is false, then it will run (and compile the views normally just fine).
OS: Server 2008 R2, all updates applied at time of writing.
I am trying to write a macro that accesses an XML file external to the editor.
For some reason, I am getting error messages on everything within the System.XML namespace 'Type XmlDocument is not defined' 'Type XmlTextWriter is not defined' 'Type XmlElement is not defined' ( etc... etc... etc... )
I've imported the namespace at the top of the editing context within the macro IDE:
Imports System.XML
I have also tried to reference the namespace members with a complete namespace reference: System.XML.XmlDocument
It didn't work. It is still being indicated as undefined.
I've tested the code from within a stand-alone console app, and it works fine.
From this, am I to conclude that the System.XML namespace is not accessible from the macro facility?
project was clean after release build, but when i ran "Run Code Analysis" i got 256 errors. the error below is one of them. will be great help. if anybody can explain, what is the meaning of this error?
I'm using Visual Studio 2008 Query Builder and am trying to pass a value to a parameter that uses the IN OPERATOR.Here is my sql from qb:
SELECT COURSE_TITLE, INSTR_NAME, ADMIN_UNIT FROM vwHRIC_EC_ContractSummary WHERE (ADMIN_UNIT IN (@ADMIN_UNIT))
The trouble I am having is that if the parameter @ADMIN_UNIT contains more than one value such as (8X, CV) that the query doesn't return any data. If I run the same query with only one value such as (8X) it works fine.I have tried different formats like (8X, CV), ('8X', 'CV'), (8X; CV) but none have worked.I ran this same query in SQL Server Management Studio and and it returns data no problem but can't get it to work in Query Builder for my aspx application.Does anyone have any experience with this problem and how did you correct it?
