Did you mean that you cannot get/read this link?

If you are reading from a Spreadsheet file, try this:



Then just write the new array to the file.

Jeyanthi,

Dont keep repeating the same que even after you have got the clearest of the answers.

Read the text file into a Str indicator, convert it into a Str Arr [1D or 2D based on your file contents], then rip the corresponding column [if it is a 2D Str Arr], do a search & delete operation for the required element inside a while loop, stop the loop if the condition that all the instances of the required element are removed from the array and then stop the VI.

I hope this is clearer than the diagrammatic explanation of Mike.

After all, a picture is worth a 1000 lines.

Well, to remove all lines with cde from a text file, there is no need to make it into an array.

Simply replace all instances of "cde/n" (in \-codes display) with nothing and write it back to the file.

You might need to adjust things, depending on the end of line definition (\n vs. \n\r for example).

Hey MIKE I just built the exact same block diagram that you have posted because I am wanting to resolve a similar issue but I keep getting error 74, does it appear that anything is wrong with mine?

Thx,
