Multi-threading in .NET: Introduction and suggestions

This article uses the C# type shorthands throughout - int for Int32 etc. I hope this makes it easier for C# developers to read, and won't impede any other developers too much. It also only talks about the C# ways of declaring variables to be volatile and locking monitors. Developers using other languages can find the equivalents in their own preferred environment, I'm sure.

ArrayList.ToArray fails!


In my app, I have code similar to the following:



               ArrayList alStartFrames = new ArrayList();
                byte[] abytTest = { 1, 2 };


                byte[] abytCombinedFrame = (byte[])alStartFrames.ToArray(typeof(byte));

            catch (Exception ex)

The call to ToArray always fails and the exception is caught even though I'm pretty sure alStartFrames is an array list of byte arrays. Anyone have any insight on why this is happening?! TIA

Use BDC data in list as multi-select column

I have a document library that uses values from another system for its metadata.  Right now, we copy the values from the primary system into SharePoint so users can choose them.  I want to find a way to use the BDC connection that I have set up to automatically pull those values.  The problem is that the current metadata is set to multi-select.  So, I have a file that is in the library and it can be used for multiple clients - clients is a column in my library and users can select many entries.  When I set up a column to pull BDC data, it only allows single entry.  Does anyone have any ideas?

Mission Impossible? Use Javascript to Disable a Multi-Line Rich Text Field


Hey Community,

Here's a tough one that I have struggled with and so far have not been able to find an answer for - how do you use Javascript to disable a multi-line rich text field.  I have customized a SP Edit form by adding a CEWP.  In the CEWP I have added the Javascript below (only a partial code sample provided) to disable several fields in the form.  The code works fine for single line text fields but it does not work for multi-line rich text fields.  Any suggestions?

<script language="javascript">
//This runs the function when the form first loads

//This locks the fields the users should not modify
function lockFields()
  var theInputTFTitle = getTagFromIdentifierAndTitle("Input","TextField","Title");
  theInputTFTitle.readOnly = true;
  theInputTFTitle.style.color = 'gray';
  //alert(" Value: " + theInputTFTitle.value);//for testing

   var theInputDDLReplyStatus = getTagFromIdentifierAndTitle("select","DropDownChoice","Reply Status");
  theInputDDLReplyStatus.disabled = true;
  //alert(" Value: " + theInputDDLReplyStatus.value);//for testing
