ok so ive decided to start back at step 1 with a simple text module. and here is what i have:

ascx:
<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="Main.ascx.vb" Inherits="TestModule2.Main" %><h2>DNN TEST MODULE 2</h2>

ascx.vb:
Namespace TestModule2
    Partial Class Main
        Inherits PortalModuleBase
       Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        End Sub

    End Class

End Namespace

I checked the namespace in properties and it is "TestModule2"

Now i put the module into the dnn page and get this error:

Error: testmodule2 is currently unavailable. DotNetNuke.Services.Exceptions.ModuleLoadException: 'TestModule2.Main' is not allowed here because it does not extend class 'System.Web.UI.UserControl'. ---> System.Web.HttpParseException: 'TestModule2.Main' is not allowed here because it does not extend class 'System.Web.UI.UserControl'. ---> System.Web.HttpParseException: 'TestModule2.Main' is not allowed here because it does not extend class 'System.Web.UI.UserControl'. ---> System.Web.HttpException: 'TestModule2.Main' is not allowed here because it does not extend class 'System.Web.UI.UserControl'. at System.Web.UI.TemplateParser.ProcessError(String message) at System.Web.UI.TemplateParser.ProcessInheritsAttribute(String baseTypeName, String codeFileBaseTypeName, String src, Assembly assembly) at System.Web.UI.TemplateParser.PostProcessMainDirectiveAttributes(IDictionary parseData) --- End of inner exception stack trace --- at System.Web.UI.TemplateParser.ProcessException(Exception ex) at System.Web.UI.TemplateParser.ParseStringInternal(String text, Encoding fileEncoding) at System.Web.UI.TemplateParser.ParseString(String text, VirtualPath virtualPath, Encoding fileEncoding) --- End of inner exception stack trace --- at System.Web.UI.TemplateParser.ParseString(String text, VirtualPath virtualPath, Encoding fileEncoding) at System.Web.UI.TemplateParser.ParseFile(String physicalPath, VirtualPath virtualPath) at System.Web.UI.TemplateParser.ParseInternal() at System.Web.UI.TemplateParser.Parse() at System.Web.Compilation.BaseTemplateBuildProvider.get_CodeCompilerType() at System.Web.Compilation.BuildProvider.GetCompilerTypeFromBuildProvider(BuildProvider buildProvider) at System.Web.Compilation.BuildProvidersCompiler.ProcessBuildProviders() at System.Web.Compilation.BuildProvidersCompiler.PerformBuild() at System.Web.Compilation.BuildManager.CompileWebFile(VirtualPath virtualPath) at System.Web.Compilation.BuildManager.GetVPathBuildResultInternal(VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile, Boolean throwIfNotFound, Boolean ensureIsUpToDate) at System.Web.Compilation.BuildManager.GetVPathBuildResultWithNoAssert(HttpContext context, VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile, Boolean throwIfNotFound, Boolean ensureIsUpToDate) at System.Web.UI.TemplateControl.LoadControl(VirtualPath virtualPath) at DotNetNuke.UI.ControlUtilities.LoadControl[T](TemplateControl containerControl, String ControlSrc) at DotNetNuke.UI.Modules.WebFormsModuleControlFactory.CreateModuleControl(TemplateControl containerControl, ModuleInfo moduleConfiguration) at DotNetNuke.UI.Modules.ModuleControlFactory.LoadModuleControl(TemplateControl containerControl, ModuleInfo moduleConfiguration) at DotNetNuke.UI.Modules.ModuleHost.LoadModuleControl() -

Glad you got it worked out.

Normally, Visual Studio should update your designer files for you so that you don't need to manually change them. But, for various reasons, that doesn't always happen. 

In any case, now that you have that basic setup/template squared away, the rest is really just normal .NET stuff for building out the functionality.
