Daily Tip - Update AddRemoveProgramsIcon (and other properties) in a Visual Studio Installer Project

6/11/2019 8:35:00 PM -- Ted Krapf

So this one drove me nuts.  It seems soooo simple. I have a Visual Studio 2017 solution with a Window Service Project and a Installer Project.  For the life of me, I could not figure out where to update the specific properties that would allow the installer to: Name the application correctly (if a friendly name) Specify other text values like Author, Description, Manufacturer, Title, ProductName, etc. ...

ZeroSSL with IIS 10

5/3/2019 5:11:00 PM -- Ted Krapf

I have an IIS 10 server behind a VPN/Firewall, and was bound and determined to use Let's Encrypt even though the server can't be reached by Let's Encrypt to authorize the SSL certificate request. I ran across www.zerossl.com, but was very confused has how to successfully complete the process.  Here's my suggestions that allowed me to get it working:   In IIS, create a Certificate Request (CR).  Copy the contents of the CR to the clipboard....

MinerGate.com Review - Mixed Emotions

2/3/2018 6:44:00 AM -- Ted Krapf

During the 2017 Q3 Crypto-boom, I finally decided to look into cryptomining.  I understood it at a very high level, but had never gone past understanding it conceptually.  As with any good project, I first started with research.  I wanted to know things such as: Is it worth it? What kind of hardware do I ideally need? What hardware can I get away with to get my feet wet? What coins can be mined, which cannot? ...

Account Breach Monitoring

9/20/2017 3:36:00 PM -- Ted Krapf

As a software developer that has to deal with user accounts, one of the topics always in my mind is security.  Is the box/vm/host secured? Did we implement strong enough password/login rules? What ciphers are enabled? Have the rules changed? Are the users doing something crazy that could compromise the security of the system? As with social engineering, the weakest link in a well designed security model is usually the users.  So, what happens if one of the us...

DBML Visualizer VERY Slow - solved!

3/29/2017 8:15:00 PM -- Ted Krapf

Greetings fellow coders! I've had this super annoying recurring issue with Visual Studio (2010, 2013, not sure about 2017 yet as I haven't started using it on a daily basis yet), the DBML visualizer, and Windows 10 --- the DBML visualizer is just dog slow and frustrating to work with. After some snooping around and looking through task manager, I realized that tabtip.exe was interfering with Visual Studio's DBML editor. T...

Excel Column Letter To Number.com

4/8/2016 3:06:00 PM -- Ted Krapf

Have you ever been working with a large Excel or other spreadsheet document and think, "man, I wish I could look up what the number equivalent of column BD is!"?  Me too! So I built a crazy simple web app that converts an Excel column letter (or letters) to its numerical value.  For example, BD = column #56.  I frequently use this for figuring out the column number when doing a VLOOKUP.  Or when I'm working on very wide spreadsheets. You can find the free E...

asp:Menu Flicker on Page_Load - Solved

Have an asp:menu that is flickering on (showing all the sub menus) on page_load and/or post back?  Of course you do, because that server control is pretty squirrely.   Here's the simple CSS fix that corrects the issue: /* fixes ugly menu flicker */ .menu ul li ul { display: none; } .menu ul li { position: relative;  float: left; list-style: none; } .menu ul li ul li { width: 100%; }

Offline ClickOnce app with command line parameters

3/9/2015 9:46:00 PM -- Ted Krapf

So the need for a client's offline ClickOnce app to have command line parameters came up again. (oh boy). The Microsoft docs initially spec'd out that you can't do this when the ClickOnce app is an "offline" app.  But since .NET 3.1, there is a trick you can use to make offline ClickOnce command line parameters function. The scenario is this: Client has a ClickOnce app that gets updated (redeployed) by their developer fr...

IIS7 FTP 530 Home Directory Inaccessible SOLVED!

So this post is definitely going to fall into the "rants" category of my blogging.   I can't tell you the number of times that I've attempted to setup Microsoft's IIS FTP services.  IIS6, IIS7, IIS7.5.  Now, don't get me wrong, if you want a simple FTP site so you can maybe publish web content or simply have one user account, it's a quick solution without adding any software to your box.  But the second you even start to think about user directory ...

Project Time Tracking - The Best Solution

Dynamic PayPal Buttons without using tags

10/16/2013 3:21:00 PM -- Ted Krapf

A client of mine recently wanted to collect payments on her website for event registration with her PayPal account.  The catch was, Adults were $10 ea, Children (3-12) were $8 ea, and Children (3 & younger) were $5 ea. So I set out on an adventure to figure out how to do this.  Obviously we didn't want to make a PayPal button for every possible combination of registration possible, that would be of been maddening.  Instead, ideally I wanted to build a form on her site using...

Oh Silly Hyphen - Prevent Line Break on Hyphen

4/29/2013 7:27:00 PM -- Ted Krapf

Here's a cool thing I learned today.  I had an issue where a customer's webpage contained a word that required a hyphen to be grammatically correct: pre-plated.  The word pre-plated appeared at the end of a line in a set width column.  Internet Explorer would render the word on two lines instead of one.  This would also happen when zoom levels other than 100% were set in other browsers and/or when the responsive design would kick in. In other words,...

Sounds simple enough right?  The first thing we tried together was scouring the web for a VBA script to do this.  Seems simple, get a list of the files in a directory, open each doc, and copy and paste its contents into the m...

End of the World?

12/18/2012 4:18:00 PM -- Ted Krapf

So, the Mayan's 'predicted' the end of the world?  Seems strange that they would do such a thing.  I guess every civilization has thought of their beginning and their demise.  As advanced as the Mayans were, their mathematics didn't take leap year into account.  The actual number of days in a year is 365.2425, not 365.  This is because a day is not precisely 24 hours. Now, since the Mayan's didn't take this into consideration, they had a roundi...
