Mail subject with non-standard characters

-

I was thinking about good example uses for the Base64 Encoding utility I posted last week, and then I remembered: e-mails!

Sending an e-mail from your application is a pretty common task. Let's say your client wants to be automatically informed when some conditions are met in the plant. So you do it, and probably use the Send Email using SMTP Cient.vi that comes with LabVIEW (since LV2013) and allows the use of secure mail servers, as Gmail.

So far, so good. But what happens when you put some non-English characters in the subject line? This is usual for us Spanish speakers, and the results are not as intended, but garbage text on the other side.

The answer is to use an encoded-word syntax. In this case we'll use Base64 and the VI I uploaded. The change needed in the mail client VI is minimum:

Just encode the text in Base64, encapsulate it as indicated, and your subject line will be readable in any mail client, as you can see in the lower image.

SNMP library for LabVIEW

-
Imagen
SNMP (Simple Network Management Protocol) is a fairly common protocol for communicating with network equipment. It's fast, lightweight and standardized. Unfortunately it's not quite as simple as its name implies and LabVIEW doesn't support it natively. Some years ago I was in the necessity of using SNMP from a LabVIEW system to control some hardware. I started looking for already implemented solutions and found a library developed by Mark Yedinak (great work!). It was useful since it demonstrated it could be done and how, but I needed more control over the operations, so I had to read the protocol down to the low level bytes and implement what I need by myself. Yeah, pretty hard and with time constraints no less. Anyway, here it is. Download (Library in LLB file for LabVIEW 2016) See the examples folder to grasp the basic use. Probably you'll need no more than these sets of VIs to send and retrieve data and to get traps sent by your equipment. To integrate

Base64 Encoding

Long time no see! Today I'm here to talk about Base64 encoding and how to do it in LabVIEW. What is Base64 and what is used for? Base64 is a six-bit based encoding mechanism that uses only printable characters from the ASCII table (lower and upper case letters, numbers, and three more characters, usually "+/="). This means it can be represented in any textual environment, though obviously adds an overhead respect to the original code since two bits of every byte are unused. You will find B64 mainly in mail applications (to send attachments), but lately it's been popular in URLs and HTML too. The concept is to insert small chunks of data directly as B64 text to avoid recurrent callings for files through the web. For example, you can embed an image inside your HTML or CSS file. It's not my intention to delve too deep in this aspect, but for an image tag the resulting HTML code would look like this (let's assume a JPG file): <img src="data:imag

Retrieve CPU temperature

Lately I had to check the CPU temperature in a critical acquisition system, and I thought it could be a good thing to share here. I know there are several applications to do this and much more, but getting it from our code allows to react conveniently to any event. Now, IMPORTANT, the VI doesn't work on its own. First you must download the Open Hardware Monitor . Extract OpenHardwareMonitorLib.dll from the zip file and put it in the same folder the VI is located. The objects exposed in it use .NET Framework 2.0 and above, but that shouldn't be a problem in any modern machine. On the other hand, this works only for Windows , obviously. And remember, the application (either an .exe or the LabVIEW IDE) must run with administrator rights (otherwise you'll get error 1172 ). Download (VI for LabVIEW 2016) Now, if you haven't worked with .NET functions in LabVIEW, this can be a good opportunity to familiarize with them. Let's take a look at the code. First we
