• Software Development for Windows Vista Send reminder mail through workflow and log History for each activity

  Hi, 1. I have attached a workflow to a sharepoint list. I want to send out reminder mails to people at specific intervals, say every 2 days, if a particular column in the list is not updated. My question is how do I model my above requirement of sending reminder mails If possible, kindly provide sample code. I have onWorkflowActivated activity as my starting activity and have also included onWorkflowItemChanged activity in my wf, which will trigger once an item is changed in the list. I considered using Listen activity (with delay activity in one branch and rest of the execution code in the other) or wrapping onWorkflowItemChanged event in a while loop but am unable to get it correctly. Can somebody assist 2. Another small quer ...Show All

• Software Development for Windows Vista Remote Desktop still an issue

  According to some MS documents (e.g. http://www.microsoft.com/whdc/system/vista/services.mspx), it should be possible to use CreateProcessAsUser() API in a Vista service to create a process in user session.

• Internet Explorer Development Info targeted to frame by host app - opening in a new Window in IE7

  I have a host based application which when called from one frame, returns forms and/or information into another frame. IE5 and 6 work fine. When used in IE7, the returned html stream is sent to a new window (not tab) instead of going to the target frame in the original document. Is there a problem with IE 7 in handling these interactive streams targeting frames Thanks, Steve   After some experimenting and research, I discovered the problem. There are several sites under the URL regis.state.va.us . Some of the pages that were pointing to the sites underneath using the URL www.regis.state.va.us .

• SQL Server Function that returns table

  Hello, Is there any way to write a function where I can write some code and at the end of the code return a entire table as parameter Looking at the options for Create Function there are two choices that return a table. The first is an in-line function. In this case you do not have to define the columns of the table, but you can only have a single select statement. So, that won't work. It is possible to have a general multi-statement function that returns a table, but that requires that the columns be known in advance. Assuming that there was value in having a function that had constant columns, but came from different tables -- maybe you have a number of name-value-pair type tables -- you now ha ...Show All
