 | Access is more suitable for small, single-user databases. For something of your scale, "thousands of client programs that will modify the database simultaneously" you need something more industrial strength. You need a full blown SQL server. You may be able to get away with the free version of MS SQL … |
| | Why not just use the free version if vb.net? You can create a form and drop all the controls on it. You don't have to write any code to create a mock-up of the GUI.  |
 | I used the same technique as everything else. Practice. The only way to get good at something is to keep doing it. I also had some excellent instructors along the way (and a few really bad ones).  |

 | Re: Favorite song I'm also big on classical. My favourite at the moment is Krystian Zimerman playing Chopin's Ballade #1 in g minor. You can see/hear it [here](http://www.youtube.com/results?search_query=krystian+zimerman+chopin+ballade+1). The pianist is insanely good. |
| | I had a similar problem. I have lost some hearing in the higher frequencies and was looking for a way to adjust the sound over all applications. I found Equalizer EPO.

| | Re: Auto Tags If there is no difference between tags and content text when searching, what is the point in duplicating the text via tags?  |
| | It wasn't me who downvoted but as a guess, I'd say it was an overly complex solution to a simple problem. In my opinion that didn't justify a downvote so I upvoted to cancel it.  |
| | But Americans (and Canadians) eat a lot of beef which requires much more land per pound of protein to produce than other forms of protein so that skews the numbers. Also, what is the definition of "living requirements"? Is it bare minimum to keep alive or comfortably alive? Are we …  |
| | You should be using TRY/CATCH rather than **On Error**. Also, because you haven't included the code for **ExecSQL** or the text of any error message there is no way to offer meaningful suggestions. |
| | Somehow I think we are getting lost in the explanation which is unclear. I can't make heads or tails out of your description. Can you perhaps just give us some sample input and what output you expect to get? I suggest you avoid terms such as "like" because what I … |

| | In true Microsoft fashion they have made the download process so counterintuitive that your chances of getting what you want is near impossible. Fortunately someone has created a "simple" [12 step process](http://www.istartedsomething.com/20140616/the-12-step-process-to-download-microsoft-sql-server-express-2014/).

| | Re: 4K file size? My guess is that 4k files would be around 4\*1024 bytes. Seriously though, the size of 8 minutes of 1080p could vary greatly depending on the bitrate, frequency of keyframes, motion, etc. A video with low motion should have higher compression. A video with lots of motion or frequent scene … |

 | Are you looking for free or are you willing to pay? Before retiring I had to coordinate the scheduling of dozens of processes with varying types of triggers. Some were triggered on a time schedule and others were triggered by the appearance of files in folders. I found [adTempus](https://www.arcanadev.com/adtempus/) a … |
| | Re: Reminder Can you be more specific? What is the trigger? Is it based on date/time? Is it based on some particular action in the database? Is the database on a local machine? What kind of database is it? Does it even matter? Do you know how to access the database? Are … |
| | Re: New Forums Several times a day I browse the vb.net forum (and a few others) to see what's new and to check if there are any questions for which I can provide feedback. What happens to those questions that don't fit into an existing forum? If, for example, I had expertise in …  |
