          I have been using WCF LOB Adapter Pack to sync SAP HR data into Microsoft Active Directory. It has been working ok in 32 bit OS. But, when I tried using it in a 64 bit OS, I was gtiteng the error “Cannot Load Microsoft.Data.SAP.SAPClient or any of the dependencies”. I installed 64 bit WCF LOB Adapter Pack before trying it out. I tried installing 32 bit version into my pc and it won’t let me install it as another version of the Adapter Pack was installed already. I will try some other way. But, if anyone have any information regarding this, please post the solution to fix it.

          Needed to put you this very little note so as to give many tahnks again on the lovely tricks you have featured above. It was so tremendously generous of you to offer unreservedly all that a few people would have advertised as an e-book in making some bucks for their own end, principally considering that you could have done it if you wanted. The tactics also worked as a good way to understand that other people online have a similar fervor similar to my own to find out a great deal more in terms of this problem. I think there are thousands of more enjoyable times ahead for individuals that browse through your website.

        (I’m not sure if I’m posting this in the ccrreot place as I was unable to post it from the Dashboard.)The type of physician I would like to work with is a gerontologist. A gerontologist specializes in caring for the elderly. I have a fondness for our older population. They built out society and lived in a time that many of us can learn from. I would take great pride in caring for them as they age. In my opinion, working with a doctor that shares my passion and excitement would be the ideal work environment.The type of physician I would not be as excited to work with would be a proctologist. To be completely honest, I just don’t think I have what it takes to be in that environment. It’s important to be professional in any medical environment. I believe my sense of humor would not allow me to be as professional as I would need to be. I would also prefer not to work with ophthalmologist. Several years ago I spent a week with my grandfather at a specialist to have cataracts removed. I found it very difficult to watch the videos of my grandfather’s up coming procedures. It wasn’t difficult caring for my grandfather after surgery, but I must admit the pre-op was an experience that I would not want to assist in on a daily bases.
