 | I found a bug in the PL/1 compiler (verified by my professor) that caused me to had in an incomplete project. I spent two days trying to figure out what I was doing wrong until I finally approached my professor. Anyone remember PL/1?  |
 | I presume the error you got was regarding incorrect SQL syntax. You didn't post the error message. Without seeing the actual query, determining the problem will be, well, a problem. The actual query passed to the database engine depends on 1. the constant strings like "UPDATE tbl_System" etc 1. the … |

| | Lacking code, I would hazard a guess that it is not doing a running calculation (1+2+3) but only displaying the result of the last operation (2+3).  |
| | I can't take it anymore. At first it was only occasionally. Now it seems that every time I turn on the TV someone else is doing it. Doesn't our school system teach English anymore? I am referring, specifically, to pronouns. At least three times today I have heard expressions like … |

| | Skype used to have a setting that would allow me to block all unsolicited contact requests. Shortly after Microsoft acquired Skype this feature was removed. I used to get 2-3 requests per week and it was easy enough to delete-and-report-abuse although I suspect nobody ever actually looked at these reports. … |
| | Re: 4*4 Board Game I'm not sure I follow the logic but I'm going to offer a suggestion to see if that simplifies things. The user is expected to click on a textbox and "Click" is not an event associated with a textbox. It's more of a button thing. My suggestion is to create … |
 | If you scan the folder when the app first starts and build a list of the files you can have your app notified when any new files are created. Here is an example (VB 2010) you can run. Just create a new project and add a listbox control named `lbxFiles`. … |
| | In my experience your boss determines whether your workplace is heaven or hell, or somewhere in-between. In my 29 years at one corporation I had four different bosses (for the same job). I was part of a group of 5-7 real-time system software specialists. My first boss (male) tried to … |

| | From what I've read, the upgrade uses your existing registration (available from your current installation). The upgrade can be done (supposedly) without having to reinstall any of your existing apps. Once you have done the upgrade, a hash value of your current basic hardware is sent to Microsoft where it … |

| | At [ConnectionStrings.com](https://www.connectionstrings.com/access-2013/) the string for Access 2013 (standard security) is Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\myFolder\myAccessFile.accdb;Persist Security Info=False; Try specifying the fully qualified file name for the database. It also might help (more info) if you comment out the try/catch logic and get the actual error message instead of masking it with your own. |

| | It is one thing to point out perceived shortcomings of someone else's work. It's another entrely to get personal. I'm always in favour of rational and constructive criticism. However, referring to a feature, or lack of one as "stupid" is not rational or constructive. It is just rude. I can … |

| | Fields are zero-relative. You *could* index them by (using the correct syntax) healthlbl.Text = reader(0) strengthlbl.Text = reader(1) but this is bad practice because if you change the query you might brreak the code. You should, instead, index using the field name as in healthlbl.Text = reader("health") strengthlbl.Text = reader("strength") … |

| | I use Skype frequently for voip. After I reboot, and for an indefinite time after, everything works fine. But eventually my microphone (Dell built-in) stops working. The party at the other end no longer hears me. It's not just Skype. Windows Sound Recorder doesn't pick up anything. Neither does Audacity. … |

| | What do you mean by "connect it to the database"? Are you saying that you cannot connect with the database or that you cannot encrypt/decrypt data to/from the database? It would also help if you commented your code. When I see code with no whitespace and no comments I mostly … |

| | In 29 years at my former place of business (approx 5000 employees) I've seen two times when consultants came in to administer personality tests. Each time we were given a fancy pop-up card with a colourful graph to display on our desks for the dubious benefit of promoting better interaction …  |

| | One time I was able to recover the text only from a corrupt word file by using strings.exe which is available as a free [SysInternals](https://technet.microsoft.com/en-us/sysinternals/bb842062.aspx) tool. That program will extract all text strings from any file. If the file is compressed then you are likely out of luck. |

 | That happens with technology. At first it is a convenience, then we become dependent on it. Think about modern agriculture. We are so dependent on non-sustainable techniques that we will eventually be unable to feed everyone (and I'm not talking just third world countries). What happens when antibiotics are no … |
| | Re: Nature's Temper Here in Winnipeg we used to have occasional floods from the Red River. The one in 1950 caused widespread destruction. Since then we built the Floodway which diverts the water around the city. In terms of construction, it was a larger project than the building of the Panama Canal, however, … |
 | Just a thought - I think you would be better off parsing the numbers as integers rather than strings. To get the two "parts" of a number you can do num Mod 1000 'for num = 98765 this results in 765 num \ 1000 'for num = 98765 this results … |

| | I can't try your example locally but I have a couple of suggestions. First, I suggest you have a look at [this tutorial](https://www.daniweb.com/software-development/vbnet/tutorials/477520/how-to-use-backgroundworker-to-create-threads) about Background Threads. It explains how to use delegates to update foreground controls (which you will need to update a progress bar). The second thing is a … |
