• Fix Uninstall Issues with Visual Studio Versions

  Have you ever installed a BETA or CTP or an RC build of some Microsoft product such as Visual Studio, and then been faced with the unhappy situation that it could not find the installation sources when you attempted to uninstall the product, or it just didnt uninstall cleanly leaving traces of Registry entries that prevented you from installing a later version?Its certainly happened to me several times.

• How would you code this: Grid-breaking shapes

  - by BeachRunnerJoe

  I'm a person that learns best from example. Currently, I'm diving into the field of Web Development after fifteen years of developing desktop apps. I'm still getting used to all the web technologies used for developing modern web sites and everywhere I look, I see cool little UI elements and question how they're implemented. So I thought I'd ask you, the web experts...the wexperts :) What are some straight forward or creative ways you could code this grid-breaking arrow... The basic layout for this page looks like... What would the html/css code look like? Would you split the image into multiple images or could you use a single image? I'm sure this is a really simple concept and it completely boggles me. I'm sorry if this is a strange question, remember I'm a noob! :) Thanks in advance for all your help! Here's a link to the original tutorial where I found these images

• use file or class for documenting classes in doxygen?

  - by AlejandroVK

  Hi all, This surely is a noob question, but I can't find an answer in Doxygen documentation. I'm not sure whether using: @file or @class when documenting my header files. The reason is that if I put file, then all the comments appear in the Files tab only, but not in the Classes tab (per each). For cpp it's ok, I just use file and it's good, but if I use both file and class in the header (file at the beginning and class right before the start of the class declaration) then I get duplicated entries for the class in the generated documentation... What I'm doing wrong? Any suggestions? Ideas? Regards, Alex

• If timestamp is deprecated, why do none of the current db tools support rowversion?

• MySQL Update Trigger with Conditions

  - by user1760656

  I have a PHP app that inserts 'Pass', 'Fail' or 'NA' into fields TEST1, TEST2, TEST3... through TEST15. I have a field called OVERALL that needs to be automatically updated with 'FAIL' if any of the TEST1-TEST15 fields contains 'Fail'. I'm pretty sure I need to use a trigger containing the update statement and either CASE or IF, but I haven't been able to nail down the exact syntax. Can anyone please help a MySQL noob?

• Web Designer looking to learn back-end programming...

  - by Tabetha Moe

  Hello, my name is Tabetha and I have a question... I am a web designer, but I always find that while designing the layout and coding the design I come up with great ideas for websites. I would like to know where I need to start in order to learn back-end programming not only for the knowledge, but also for the challenge of it. I have searched online but can't seem to find the information I am looking for. If anyone can give me a simple, straight-forward "this is what language you need to learn" answer, or perhaps guide me in the right direction I would appreciate it ten-fold. I am a complete noob when it comes to this, so even the most basic information is probably a pearl of wisdom for me. :)
