Modifying a particular line (content) of data in a file.

[suneelkv]

Hi All,

I've a requirement with file modifications, but i'm new to Labview so couldnt correctly fix it...

My req is something like this.....

I've a file named mytemplate1.txt which is added to this post....

In that i've a line, i.e no. in attacehd is 153

"modelLanguageCode=ENU"

In that i wanna put a control to the bolded one above.

So whenever i modify that control to SPA, GER, JPJ .....

It should update the content respectively.

I tried with different file functions available in Labview 8.2 but unable to find the solution ...

So my temporary approach for this is

Concatenate string

where
Part 1 is data above modelLanguageCode=

part 2 ENU

part 3 data after "modelLanguageCode=ENU"

But this doesnt looks ideal for my req.

So please suggest any good solution....

Yep my fault,

In between the file read and the file write operations.  set the file position back to 0 using "set file position.vi" under the advanced sub pallette within the file pallette.  I have verified this works correctly.
