We are using the Planner.NET Calendar control in an application.

I have a new 64 bit Windows 7 build machine. Our source repository contains the Calendar.dll (v4.0.2357.25124, referenced in the Visual Studio 2008 project) and the licenses.licx file which contains an entry for the MindFusion Calendar:

MindFusion.Scheduling.WinForms.Calendar, Calendar, Version=4.0.2357.25124, Culture=neutral, PublicKeyToken=abcdef0123456789

(PublicKeyToken changed)

When I attempt to rebuild the application, I get the following message:

Exception occurred creating type 'MindFusion.Scheduling.WinForms.Calendar, Calendar, Version=4.0.2357.25124, Culture=neutral, PublicKeyToken=abcdef0123456789' System.ComponentModel.LicenseException: Couldn't get design-time license for 'MindFusion.Scheduling.WinForms.Calendar'
C:\Users\Me\MyProject\licenses.licx Line 1


After searching the forum, I have tried exporting the "HKLM\SOFTWARE\MindFusion\ComponentLicenses" key and corresponding "Planner.NET" value, but this has not resolved the problem.

Can you tell me what I need to do to fix the problem?

Thanks.

Thanks for your suggestion, Meppy.

I have tried your suggestion, and imported the "Planner.NET" value into your suggested registry key, but this did not fix the problem.

At the moment, I have simply copied the library and licx file from our source control repository? Do I need to install Planner.NET on the new build machine?

I have tried the following:

MindFusion.Scheduling.WinForms.Calendar, Calendar, Version=4.0.2357.25124, Culture=neutral, PublicKeyToken=null

MindFusion.Scheduling.WinForms.Calendar, Calendar, Culture=neutral, PublicKeyToken=123456789abcdef

MindFusion.Scheduling.WinForms.Calendar, Calendar, Culture=neutral, PublicKeyToken=null

None of which fixed the problem.

Yes, that registry key exists.  I have no idea what the "correct" value is for the "Planner.NET" string value, but I copied the value from the old machine which the build does work on.  Not sure if I am allowed to say what the value is on an open forum?

I'm really not having any luck with this.  I've renamed the key as you suggest, even rebooted my machine, but it still doesn't work.

Ok, another suggestion. Unfortunately the version you are using is around 5 years old and I'm having some difficulties figuring out how things worked back then.

Replicate the Planner.NET value under the "HKEY_LOCAL_MACHINE\SOFTWARE\MindFusion Limited\ComponentLicenses" registry key as well. At the end this value should be present under both keys:

HKEY_LOCAL_MACHINE\SOFTWARE\MindFusion Limited\ComponentLicenses
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MindFusion Limited\ComponentLicenses

Well that's interesting ... I just created a new Visual Studio 2008 project, added a reference to the same library file as the Visual Studio project I am having problems with, copied the licenses.licx file into the new project's folder, and the new project works:

Public Class Form1

    Friend WithEvents m_CalMain As MindFusion.Scheduling.WinForms.Calendar

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
       m_CalMain = New MindFusion.Scheduling.WinForms.Calendar
       CType(Me.m_CalMain, System.ComponentModel.ISupportInitialize).BeginInit()
       m_CalMain.Date = Now.Date
       Me.m_CalMain.Dock = System.Windows.Forms.DockStyle.Fill
       Me.m_CalMain.EndDate = New Date(2007, 5, 2, 0, 0, 0, 0)
       Me.m_CalMain.Location = New System.Drawing.Point(0, 0)
       Me.m_CalMain.MonthRangeSettings.HeaderStyle = MindFusion.Scheduling.WinForms.MonthRangeHeaderStyles.Title
       Me.m_CalMain.MonthSettings.HeaderStyle = MindFusion.Scheduling.WinForms.MonthHeaderStyles.Title
       Me.m_CalMain.Name = "m_CalMain"
       Me.m_CalMain.TabIndex = 0
       Me.m_CalMain.TimetableSettings.TwelveHourFormat = MindFusion.Scheduling.WinForms.State.Disabled
       Me.Controls.Add(m_CalMain)
       CType(Me.m_CalMain, System.ComponentModel.ISupportInitialize).EndInit()
    End Sub
End Class

Produces a dialog with a calendar in it.

Unfortunately, recreating the project which doesn't work is NOT an option because it is very large and complex.

Does this help you identify what is causing the problem?

Does it still give the same compile-time exception - LicenseException? Can you try deleting and re-adding the references to the Calendar assembly in your project?
