event receiver errors to set list item permissions

Remove your line: base.ItemAdding(properties);
this has nothing to do with your code, you already wrote base.ItemUpdating(properties); at the beginning which is at the right place.

If you where customizing the ItemAdding (and all other -ing events) event receiver, you should not call the base.Method in the SPSecurity.RunWithElevatedPrivileges() method (base.ItemAdding();). Just put it at the beginning of your method overrided for the native validation fields.)

Hello again, for your 2nd warning (or first) you should use your ex variable:

here is an exemple, I write the error in the sharepoint logs files (because it is a sharepoint event and not a webpart):

catch (Exception ex)
 {
      Microsoft.Office.Server.Diagnostics.PortalLog.LogString("Une erreur est survenue. Source : {0}, message : {1}", "DemoAttendanceEventReceiver.EventReceiver1.EventReceiver1", ex.ToString();

 }

The logs can be found in the folder:
HardDisk:\Program files\Common files\microsoft shared\web server extensions\12\logs

In french, the folder Common files is called "fichiers communs", maybe you will find another name if you don't work with the english version of sharepoint

thanks so much.

now I'm getting this error:
Error      1      The type or namespace name 'Office' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?)      C:\temp\DemoAttendanceEventReceiver\DemoAttendanceEventReceiver\Class1.cs      64      30      DemoAttendanceEventReceiver

I think my VS environment is lacking the proper sharepoint setup.

I cannot install the sharepont sdk - I keep getting an error because I'm running an x64 environment/server

Hello,

Visual Studio does not add sharepoint's references in projects by default, you must manually add this one:
right click on reference, and choose Microsoft.Office.Server (or find it in the computer where sharepoint is installed:
"C:\program files\common files\microsoft shared\web server extensions\12\isapi\microsoft.office.server.dll"

ok. but shouldn't I be able to create a custom workflow using visual studio?

I do not have any of the sharepoint content specific project types listed when I open visual studio.

oops - that was an answer to a different question

Thanks so much - that seems to have rebuilt ok.

is applying [Full Control] to this item what I should be doing? Should it be a lesser permission level? Just to edit or something?  Just curious

Also I need to apply item permissions to a group I created on the site called "Attendance Managers" they need to be able to see everything.

Once I have this built, I will need to deploy it (GAC the dll, correct?) I would appreciate some guidance as well.

I will repost my code:

using System;
using System.Security.Permissions;
using Microsoft.SharePoint;

namespace DemoAttendanceEventReceiver.EventReceiver1

    ///<summary>

            try
            {
                //stop other events from firing while this method executes
                this.DisableEventFiring();
                //add code here
                //{

how do I set permissions for the group 'Attendance Managers'? And I think I want to set requester to read once it's submitted, authorized by to edit and the group to full control.

here is my updated code:
 

using System;
using System.Security.Permissions;
using Microsoft.SharePoint;

namespace DemoAttendanceEventReceiver.EventReceiver1
{
    ///<summary>
    ///list item events
    ///</summary>

    {
        public override void ItemUpdating(SPItemEventProperties properties)
        {
            try
            {
                //stop other events from firing while this method executes
                this.DisableEventFiring();
                //add code here
                //{
                base.ItemUpdating(properties);
                //}
                ///<summary>
                ///an item being addded
                ///</summary>

ALSO - my other issue is how do I create a unique GUID when I can't install the sharepoint project sdk extensions on a x64 machine?
