Finding hidden device drivers

Image
By

I believe that Windows is a great interface; it has help spawn some awesome apps, and help many a company grow. However, that said, why do the developers at Microsoft always have hidden features. Even as far back as DOS there where routines that you could call that were called undocumented. I would hate to see a list of these now.

Some times real detective work is required to solve a problem
So how does this apply to me at this point? Well I have a Nokia N82 and have had some problems with the camera and decided to do a reset of the phone (as recommended by one of their forums). After 3 hours of wasted time I have my phone back up and running, thanks to the awesomeness of Active Sync and Exchange I never have to worry about backing up contacts and the like.

Anyway I also use my phone to connect the internet when on the road using the blue tooth modem. And the laptop could not detect the modem. After fiddling and fiddling I started thinking about the reset and that some how Windows had stored somewhere the old phone name and therefore the old modem drvier. Remembering that you could find old device drivers somehow I searched the internet and this is the result.

I found this useful for when you trying to find devices drivers that are conflicting with existing ones, thanks to the internet here is a step by step:
  • Run command prompt as admininistrator

  • Add the following environment variable:
    SET DEVMGR_SHOW_NONPRESENT_DEVICES=1

  • Now run device manager:
    start compmgmt.msc
  • And then select show hidden devices

By the way I swear this was easier in previous versions of Windows.

Needless to say I found the older driver and trashed it, and the blue tooth modem works again.

Bitcoin / Cryptocurrency – what is it and how can I benefit

By
What is it I started investigating Bitcoin when it was worth just over $1000 a bitcoin. I was interested in what it was and how it worked. A lot of people are saying we missed the boat, but I believe that everyone should at least try put a little money in now, or at least use a faucet (see below) to make a little micro-currency. You can read a Wiki article about bitcoin and its history etc. But what you need to know is that it is a currency, that is independent of country. No one really knows who invented the concept of a cryptocurrency since the person who published the paper used a nom de plume. All new cryptocurrencies work more or less the same way as Bitcoin. So as I explain below I interchange these terms. Bitcoin is the original cryptocurrency. How Bitcoin works The currency releases a coin based on a mathematical formula. There will never be more than 21 million bitcoins (other cryptocurrencies do not work like this). Each bitcoin can have divided into one hundred mil...

Access conversion NOTE1: default DateSerial in VBA/Access to SQL

By
I have started slowly converting my Access database to SQL. The reason is that I would like to take the application online. After trying to use Access's (version 2007) transfer tool, which did not work that well. I found Microsoft's SQL Migration Assistant 2008 for Access, nicknamed SSMA. Which you can download here . When you install there is a niggle about the license, which you need to download into their specified directory and it must be the name they provide. So about the create table. My one table would not convert and I could not see why. After looking at the SQL command I saw the problem was the use of DateSerial. I googled a few sites and could not find an answer The CREATE TABLE line was: [RequireUntilDate] datetime2(0) DEFAULT DateSerial(1980,1,1) NOT NULL, I clicked on the whole command and copied it and then in SQL Server Management Studio, I tried to create the table and found that if I specified the date in US date format it worked: [RequireUnti...
