Locking down your file system to protect your files is not optional. If someone can get hold of your QVW they will have the opportunity to hack into it. If you do want to scramble the string I would suggest that you look on-line for a command line encoder, you can then put a call to this in your load script. This will mean that you need to allow external scripts in your load script though. I suspect that there are on-line encryption/decryption APIs – but then you are sending your connection details off to someone else’s computer to be processed.

Hi Dmitry,

I am exactly going through the same problem of security with the external text file in an enterprise solution. Did you find any way to secure the connection, other than making sure the server is secure?

There was a mention on scrambling the password within the external text file, any idea on how this can be done? Would really appreciate if you could share what you have done in this aspect, thanks!

Unless you are using sub routines all variables are globally scoped, regardless of whether they are created in an include file or not.

I can use two includes in same script, but can i use any variable in one archive and use this same variable another?

thx! hugs!

This scenario shouldn’t cause an issue, as neither app will be writing the file so will not need exclusive access to it. The best way to find out would be to try it out. You could put a wait statement in the include file, to ensure it was open by both apps at the same time.

I’ve another question regarding the Include statement. What happens, if two two instances of qlikview access the txt at the same time. F. ex. there are running two scripts at the server and by accident the both access the include script at the same time?
Will both scripts fail, becaus they have no exclusive access to the txt file?

Thanks a lot in advance:)

This functionality can be quite useful at times – where you want it to put in a fixed value – other times you want to avoid it. The simplest way to not have it do the replace is use a different character for the $ symbol, and then replace it afterwards, ie:

set vMyVariable = sum(¬(vSelectedMeasure));
let vMyVariable = replace(vMyVariable, ‘¬’, ‘$’);

If you use a let for the initial creation of the variable you can do it in one go, but the set is useful as you can have single quotes and carriage returns in your variable definition.

Hope that helps.

When I define a variable that includes a variable, QV replaces the $(variable) with the actual value during import.

SET vKPI_AATotalCost = ‘=Sum({$<RMonth={"} If(AcctCode >= 6000 AND AcctCode <= 6999, InvAmount))';

Here for example the $(vActualMonth) is replaced with the value of that variable during import. How can I prevent that and define the variable as it is?

Hi Oli. Glad you found it useful!

Wow thanks!!! You just saved me a load of b*** ache with that little nugget of info regarding the white space.
