Get next available number using a workflow

Posted By:      Posted Date: October 18, 2010    Points: 0   Category :SharePoint
 

Hey everyone,

Here is the case.

Lets say I have item 1, 2, 3 and 5 in my list.
I want my workflow to set the next Item to 4.
Currently my workflow will set the number to 6 and so on.

Any ideas how I can achieve this with a workflow?

Before I forget, I have a List that serves as a counter.

Workflow History list - Huge number of entries.

  

Hi there,

Does anyone know if there is an issue with having a large number of entries in the workflow history list. I've got 2 sites that have only been in existence for 9months and the workflow history lists are already at 14000 entries?

Is this list size an issue?

Would growing at this rate cause an issue in the future?

Is there anything we could do about it? settings, delete routines..

Any ideas/suggestions gratefully received!

Cheers

dynamically adding sql server columns based on number of files in fileuploader

  

I want to create a new table to sql database at runtime.  The column names would be "Name", "Date", "Event".  I would also like to have one more column name "Image" but the problem is that since the amount of images will vary, I want the application to count the amount of files in the Multiple fileuploader and then add a image column to the table for the respected amount of files. 

For example if i am uploading 3 files in the multiple fileuploader, the names should be "Name", "Date", "Event", "Image1", "image2", Image3"

I also would like that table name to be name dynamically from the textbox Name when the user enters the information.

 

I have the following code to make a new table, but I dont know how to name the fields at runtime like previously asked please help!!!

 

Dim objConn As New SqlConnection("Server=<servername>;uid=<userid>;pwd=<password>;database=master")

objConn.Open()

Embeb a variable number of videos

  

I need to provide some alternate content for my non-Flash users.

I have a directory of video files that is scanned using the DirectoryInfo() function, and I want to use the results to embed all files ending in ".mov" in QuickTime players on a web form.

How would you approach this? Right now I am using the count on the array of videos to determine how many times to repeat the embed code.  But this seems inelegant.

Is there a way to have a single QuickTime player.ascx control that gets duplicated according to the number of videos available for display?


Article commenting by line number

  

I'm wondering what's the best way to approach an online article system that allows users to comment by clicking on the line they are commenting about? Essentially the same way Adobe Acrobat works with comments where you can click anywhere and the text is saved for that location.

I'm assuming a mix of jQuery would be the crux of the interface. The system would need to save comments so that when another user logs in, they will also see the other comments but they can´t edit them - only add their own.

Any suggestions would be great.


The number of members in the conceptual type ... does not match with the number of members on the ob

  

 Hello,

I've added a scalar property to an entity and now ASP.NET Dynamic Data scaffolding throws this error:

The number of members in the conceptual type 'TrainingModel.Users' does not match with the number of members on the object side type 'TrainingModel.Users'. Make sure the number of members are the same.

This happens at the following line in global.asax:
model.RegisterContext(typeof(TrainingModel.TrainingEntities), new ContextConfiguration() { ScaffoldAllTables = true });

Please help!
Thanks

Foundations: Workflow Services for Local Communication

  

This month's column describes how to use WCF for communication between a workflow and a host application in Windows Workflow Foundation 3. This knowledge should help developers with their efforts using WF3 and prepare them for WF4, where WCF is the only abstraction over queues (referred to as "bookmarks" in WF4) that ships with the framework.
