Infopath form closes as soon as you open it in sharepoint workflows.

I had a strange error as soon as a VS 2005 workflow that I wrote for Sharepoint would try open an InfoPath form it would close without giving any errors. The only error was the following in the logs: EventType ulsexception12, P1 w3wp.exe, P2 6.0.3790.1830, P3 42435e74, P4 microsoft.office.infopath.server, P5 12.0.6219.0, P6 4845c8d9, P7 9573, P8 194, P9 fileloadexception, P10 82lz.
To resolve this issue ensure that there are no empty parameter floating around in the ItemMetadata.xml files that the InfoPath form is not using. Once I removed all unwanted parameters the issue was resolved.

System.InvalidOperationException: The event receiver context for Workflow is invalid.

If the below error come up while creating sharepoint worflow:

System.InvalidOperationException: The event receiver context for Workflow is invalid. at Microsoft.SharePoint.SPEventReceiverDefinition.ValidContext() at Microsoft.SharePoint.SPEventReceiverDefinition.ValidReceiverFields() at Microsoft.SharePoint.SPEventReceiverDefinition.GetSqlCommandToAddEventReceivers(IList`1 erds) at Microsoft.SharePoint.Workflow.SPWinOESubscriptionService.CommitNewSubscriptions(Transaction txn, IList`1 erds)

The cause of this is either you didn't associate properties for TaskID, TaskProperties, or CorrelationToken activity to your createtask token. The other scenario that this comes up is when you don't assign a unique id to your Taskid. If you code looks like below:
public Guid createTaskInitiation_TaskId = default(System.Guid);
to
public Guid createTaskInitiation_TaskId = Guid.Newguid();
This should resolve the error.

Some issue with Title when generating a Excel file from a crystal report.

Two issues I spent some time resolving was:

1. When an excel file was generated from crystal reports some times the assosciated title for the column does not appear correctly.
   
2. Every time I generated an Excel file from crystal reports. The titles in the excel file were never in the same order as I had created them in crystal report.
   

Fig 1 : This will not work

Resolution to the issues above:

1. For all the columns that you require to appear in excel they must touch the details section.
2. For the Titles to be in the same order as in crystal,all fields must have the same height. For some reason the order seems to be based on height.

Below is the corrected crystal report Image.

Fig 2. This will work
