Visual Studio 2012 cannot resolve symbol or Errors control is not a member of class
Visual Studio 2012 Web Site Project (Note not a Web application, so there are not Designer.vb files) > Site works perfectly fine and using IIS and attaching to IIS to debug code.
However, if I try to build the site inside of Visual Studio I am getting lots of Errors ‘pnlName’ is not a member of ‘Page_Name’ In the code behind I am getting errors ‘Cannot resolve symbol ‘pnlName’
.ascx Page
<li style="margin-right:0;" id="pnlName" runat="server"><a href="/cart" title="Checkout" class="global-checkout">Checkout</a></li>
.ascx.vb page
Me.pnlName.Attributes.Remove("style")
I have cleaned, rebuild and nothing gets rid of these errors, but again the site works as designed, but I would like to launch and debug inside of Visual Studio.

Cor,
What I am stating is this is a solution using the Web Site Project instead of a
Web Application Project.
Web Site projects do not require Designer.vb files, Web Application Projects add Designer.vb files in the solution.
Background: I have been hired to support a very successful e-commerce site that was built by a 3rd party vendor (I had no input on the contract or specification, because I would have went with
MVC). The site works 100% correctly, however from my 2003 - 2015 experience with Visual Studio and Web Development being in Web Forms and MVC I have always built ASP.NET Solutions using the Web Application Project Templates, which compiles the code down
to .dlls.
A Web Site project does not compile the code, but simply uses the .vb files and they have to be migrated to the server with the .aspx files. http://msdn.microsoft.com/en-us/library/dd547590%28v=vs.110%29.aspx
Currently the only way I can debug this Solution is to attach to the w3wp.exe process running locally on my work station.
The Solution is comprised of two Web Sites, which I cannot get it to compile because of the following errors -
'webServerControlName' is not a member of '(Protected Code Behind Class Name)' I am reaching out to the MSDN community to see if anyone has experienced this issue with
Web Site Projects.
I hope that clears up the Project Type question.

Error on Form Designer on Visual Studio 2012
Dear Sir,
I have used Visual Studio 2012 to develop my project for a long time.
However, suddenly Designer of all Forms come an error but the system can compile the project.
Therefore, I am not able to change the design of the Form in Visual Studio.
Any Suggestion?
Thank you very much.
The following is the Error of the Designer:
To prevent possible data loss before loading the designer, the following errors must be resolved:
1 Error
The type 'System.Configuration.UserScopedSettingAttribute' could not be found. Ensure that the assembly containing the type is referenced. If the assembly is part of the current development project, ensure that the project has been built.

Best regards,
FelixHello Felix,
The info seems tell us your project is corrupt. May I ask this question, will this error reproduce when you create a new simple project? This can be divided into two scenarios:
Scenario 1: The new project is also corrupt.
In that way, your Visual Studio may already corrupt. It's time for you to repair your Visual Studio from control panel.
If it still not work, try use some common steps below to fix:
Please open an administrative CMD window and navigate to C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE and run these commands:
1.devenv.exe /safemode
2.devenv.exe /resetskippkgs
3.devenv.exe /installvstemplates
4.devenv.exe /resetsettings
5.devenv.exe /resetuserdata
Scenario 2: The new project doesnot get this issue.
In this way, we should focus on this "The type
'System.Configuration.UserScopedSettingAttribute' could
not be found"
See here from MSDN to know how we can use it in our code:
https://msdn.microsoft.com/en-us/library/system.configuration.userscopedsettingattribute(v=vs.110).aspx
Check whether your code list something like below code and check whether you have missed anything here.
//Application settings wrapper class
sealed class FormSettings : ApplicationSettingsBase
[UserScopedSettingAttribute()]
public String FormText
get { return (String)this["FormText"]; }
set { this["FormText"] = value; }
[UserScopedSettingAttribute()]
[DefaultSettingValueAttribute("0, 0")]
public Point FormLocation
get { return (Point)(this["FormLocation"]); }
set { this["FormLocation"] = value; }
[UserScopedSettingAttribute()]
[DefaultSettingValueAttribute("225, 200")]
public Size FormSize
get { return (Size)this["FormSize"]; }
set { this["FormSize"] = value; }
[UserScopedSettingAttribute()]
[DefaultSettingValueAttribute("LightGray")]
public Color FormBackColor
get { return (Color)this["FormBackColor"]; }
set { this["FormBackColor"] = value; }
Or you can copy your project content to a new fresh project and rebuild your project with new settings.

Barry

Hi,
I am getting this error from visual studio 2012 whenever i try to create the following project types:
- Workflow Custom activity
- Web parts
The error is as mentioned below
"The partial project item type does not have a value for this property"
Due to this the when I add above type of items in my project, they show a red cross icon against them.
Please let me know If have you any solution?Hi
I had same issue. Below is the solution
Installing
"Visual Studio 2012 Update 3" usually solves this problem. (You can download it through microsoft's official site at
"http://www.microsoft.com/en-in/download/details.aspx?id=39305")

I am using Sun JDK Version 1.3.0_02" and Apache/Tomcat 4.0. Both the calling and the called class are in the same directory.
Any help would be greatly appreciated.
tnx..
addiIs ConnectionPool in this "cal" package as well as PooledConnection? From the directory you are compiling from it appears that it is. If it is, then you are compiling it incorrectly. To compile ConnectionPool (and PooledConnection similarly), you must change the current directory to the one that contains cal and type
javac cal/ConnectionPool. -
Class error - cannot resolve symbol "MyDocumentListener"

java -cp .;<any other directories or jars>
YourClassNameYou get a NoClassDefFoundError message because the
JVM (Java Virtual Machine) can't find your class. The
way to remedy this is to ensure that your class is
included in the classpath. The example assumes that
you are in the same directory as the class you're
trying to run.I know it's a bad habit but I've put this file (PropertiesTest.java) and the compiled class (PropertiesTest.class) both in my bin folder which contains the javac compiler -

cannot resolve symbol

public pk ejbCreate(Sorry , its not classpath problem. You have to simply import the pk class if its in any package. I am assuming you have packaged your pk class with ejb jar file.
for eg. if your class is

then in your bean class import

Compiling error - cannot resolve symbol
Hi,
I am working on writing out this basic code for a project. When I compile, I get an error "Cannot resolve symbol" for the gpa variable. Please help!
My intention is to use the hours and points from the crHours and nbrPoints methods, and use them to calculate GPA in the grPtAvg method:
public class Student
public static void main(String[]args)
idNum();
crHours();
nbrpoints();
gpa = grPtAvg(hours, points);
System.out.println("Student's GPA is " + gpa);
public static void idNum()
int id = 2520;
System.out.println("Student's ID is " + id);
public static float crHours()
float hours = 5;
System.out.println("Student's credit hours are " + hours);
return hours;
public static float nbrpoints()
float points = 22;
System.out.println("Student's earned points are " + points);
return points;
public static float grPtAvg(float hours, float points)
float gpa;
gpa = points / hours;
System.out.println("Student's computed GPA is " + gpa);
return gpa;That's because you're doing the same thing (in a somewhat different way) with those.
The variables: hours and points have already been returned to main methd, right?Yes, but then the main method ignores them.
So, they should be available at this point in the code, is that right?Available in the sense that you can read them, but not in the sense that there are hours and points variables within scope in the main method.
You want to do this:
public static void main(String[] args) {
idNum();
float hours = crHours();
float points = nbrpoints();
//create a new float
float myComputetdGpa = grPtAvg(hours, points);
System.out.println("Student's GPA is " + myComputedGpa);

App.Xaml cannot be edited in design view(Visual Studio 2012 for Window Store).
App.Xaml cannot be edited in design view(Visual Studio 2012 for Window Store).
The
Simple Application Walkthrough specifically instructs one to edit App.xaml (because it previously had you inject a defect by changing the name of the file StartupUri property points to). So that is the scenario, or one of them. I assume it is 'valid'
to rename MainWindow.xaml to whatever you want it to be.
So there should be some way in the IDE to fix this (short of changing the file name back to match StartupUri). What is it?
Like another person here, I just edited it with a text editor and reloaded it into VS. But... -
Cannot preview SSRS report in Visual Studio 2012 - assembly does not allow partially trusted callers
Hi,
I have an SSRS report that works fine in Visual Studio 2008 BIDS. This report references a .Net assembly namely:
System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a
I use this assembly in some simple Code functions in the report. e.g.
System.Web.HttpUtility.UrlEncode(inURL).ToString
I have converted the SSRS project to 2012 and am trying to preview the report. However, I get an error relating to: "That assembly does not allow partially trusted callers". If i deploy the rdl to my local SSRS it renders fine, but
how do I fix Visual Studio to preview the report without error? This is highly annoying.
My Visual Studio version is:
Microsoft Visual Studio Professional 2012
Version 11.0.61030.00 Update 4
Microsoft .NET Framework
Version 4.5.51641
SQL Server Reporting Services
Microsoft SQL Server Reporting Services Designers
Version 11.0.3402.0
Any help is appreciated on this one.
Regards,
MrHHHi MrHappyHead,
According to your description, you used custom assembly in the report, when you run the report in Visual Studio 2008, the report works fine. When you run the report in Visual Studio 2012, the error message occurred: "That assembly does not allow partially
trusted callers". But the report works fine after you deployed it to report manager.
Only applications that are fully trusted by the runtime code access security system are allowed to access a shared managed code assembly that is not explicitly marked with the System.Security.AllowPartiallyTrustedCallers attribute. A partially trusted assembly
(one that is registered in SQL Server with the SAFE or EXTERNAL_ACCESS permission set) that attempts to access a strong-name signed assembly without this attribute causes a System.Security.SecurityException to be thrown. To troubleshoot the problem, please
refer to the following steps:
Add namespace system.security to AssemblyInfo.cs file
Add [assembly:allowpartiallytrustedcaller] to the file.
Set trust level to "Full" in web.config file
For more information, please refer to the following document:

If you have any more questions, please feel free to ask.

Weird cannot resolve symbol error.
I'm having a problem with the most simple thing, but I really don't know what is th error, maybe I can�t see the error because the lack of rest.
I have two classes, both are in a package and in the same folder.
This is are the problematic lines.
tmpLong = calculateSizeFile("sonido.wav");
tmpInt = calculateSizeSegment("sonido.wav");
SendFile file1 = new SendFile(args[0], "sonido.wav", 2, 32, 2, 2, tmpLong, tmpInt);
The SendFile is the other class and it�s a thread.
The package decalaration is:
package com.sigmatao.gde.batch;
This is the constructor of the other class:
public SendFile(String httpServlet, String file, int numberRetry, int maxTimeWait,int multiplier,int timeMin, long sizeFileToSend, int sizeSegmentFile)
Thanks in advanced for the help.C:\Temp\URL\com\sigmatao\gde\batch>javac BatchTransfer.java
BatchTransfer.java:20: cannot resolve symbol
