I have been struggling with this all day

My code runs fine and works OK but when I try to publish my site it fails with error :

Object reference not set to an instance of an object.

No File name or line information

The output window has the following

Building directory '/DotNetNuke/App_GlobalResources/'.

Building directory '/DotNetNuke/App_Code/Reports/'.

Building directory '/DotNetNuke/App_Code/GR_Marquee/'.

Building directory '/DotNetNuke/App_Code/GR_EMail/'.

Building directory '/DotNetNuke/App_Code/GuestBook/'.

Building directory '/DotNetNuke/App_Code/'./: Publication (web): Object reference not set to an instance of an object.

Pre-compilation Complete

It looks to me as if its trying to compile the App_Code directory - why there isnt anything there???

I have followed Michael Washingtons tutorials and cant see what I have done wrong

The config has the following in it

<codeSubDirectories>

<add directoryName="Reports" />

<add directoryName="GR_Marquee" />

<add directoryName="GR_EMail" />

<add directoryName="GuestBook" />

these appear in the codeSubDirectories in the compilation section of the config

Most confused as I dont know how they got there

I have looked at that there is nothing that tells me how to get round the problem I am having

I will look at the aspnet compilation over view but I still dont understant what its trying to do compiling this directory

This was compiling OK earlier  until I took the unwanted SQL provider and controller code out

No you have assumed correctly - I have followed the dev tutorials and everything seems to work fine then I look at the packaging tutorial - I was using the term publish from the comment below

"Create the compiled assemblies

From the Build menu, select Publish Web Site"

So I am trying to package my modules properly - which I have also accomplished without problem as long as I do not precompile and replace the .vb .ascx and files with "compiled" ascx and dll files

As soon as I try and compile my module when I retrieve the said code, install and run it  then errors occur

I have reviewed the tutorials and set up a new instance using 4.5.1 install  - I overwrote that with the 4.5.1 source which I then used the project.sln to open Viual Studio ( The source download did'nt seem to be able to set up the database for some reason)

I installed my module as a source code PA and tried compiling and building a PA with dll's (as in your packaging Tutotrial)

I now get anothererror on installing the compiled module ( again the source PA seems to behave fine)

DotNetNuke.Services.Exceptions.ModuleLoadException: c:\hosting\w\m\u\clientdnn\DesktopModules\GR_EMail\ViewGR_EMail.ascx(20): error BC30456: 'Page' is not a member of 'ASP.desktopmodules_gr_email_viewgr_email_ascx'. ---> System.Web.HttpCompileException: c:\hosting\w\m\u\clientdnn\DesktopModules\GR_EMail\ViewGR_EMail.ascx(20): error BC30456: 'Page' is not a member of 'ASP.desktopmodules_gr_email_viewgr_email_ascx'. at System.Web.Compilation.BuildManager.CompileWebFile(VirtualPath virtualPath) at System.Web.Compilation.BuildManager.GetVPathBuildResultInternal(VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile) at System.Web.Compilation.BuildManager.GetVPathBuildResultWithNoAssert(HttpContext context, VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile) at System.Web.UI.TemplateControl.LoadControl(VirtualPath virtualPath) at System.Web.UI.TemplateControl.LoadControl(String virtualPath) at DotNetNuke.UI.Skins.Skin.InjectModule(Control objPane, ModuleInfo objModule, PortalSettings PortalSettings) --- End of inner exception stack trace ---

I am also a litte confusd- the tutorial indicate's that l the dll's will have the folder name in their title somewhere - when I look for dll's  - there are 2 - the names are of the form App_Web_viewgr_email.ascx.96aa4f0a.dll, App_Web_settings.ascx.96aa4f0a.dll

is this correct? - I would also like to tidy these up if at all possible.
