Add Delete From String Function to LabVIEW

[Ryan_Wright_]

If I'm not mistaken, there currently isn't a single function that deletes a certain number of characters from a string. This can be done in a variety of ways using existing string functions, such as the example shown in the picture below. It would be really nice if LabVIEW contained a Delete From String function with offset and length inputs as illustrated in the same picture below. If you didn't wire up the length, maybe it could delete the remainder of the string and maybe an unwired offset could default to 0, similar to the String Subset function.

Another option is to use the String To Byte Array (which is a no-op), Delete From Array, and then Byte Array To String (another no-op).

Use "Replace Substring" with an unwired or empty replacement string:

As described by raphschru, the Replace Substring function can be used to remove a section of a string based on index and length. Additionally, you can use the Search and Replace String function (with an empty 'replace string') to remove a section of a string based on its value.

Thanks for the feedback, everyone. I had forgotten about these ways of deleting characters from a string.

It's not entirely a no-op.

The combination turns a sub array into a normal array, and this could significantly effect performance:
