String replace 'empty' by ends in Access vialotion at addres

[Dick99999]

The following code ends with the message:
Access violation at Address 00419AF5 in module 'msched.exe' Read of address 00000000.

It seems a heavy penalty for substituting 'nothing' by 'nothing'. Probably "a should not happen" case, yet difficult to pinpoint in a large script.

The code b.t.w. tries to delete the extension of a filename, which is not there in the sample.

Code: Select all

let>dataDirNew={"new"}
let>transfFile_VAR_1={"ir"}


    let>fnNew=%dataDirNew%\%transfFile_VAR_1%
    ExtractFileName>fnNew,fnOnly
    ExtractFileExt>fnNew,fileExt

   // next statement will end in a access violation
    StringReplace>fnOnly,fileExt,,fnzOnly

let>dataDirNew={"new"}
let>transfFile_VAR_1={"ir"}


let>fnNew=%dataDirNew%\%transfFile_VAR_1%
ExtractFileName>fnNew,fnOnly
ExtractFileExt>fnNew,fileExt
IF>fileExt=""
StringReplace>fnOnly,fileExt,,fnzOnly
ELSE
// next statement will end in a access violation
// There is nothing to replace ..and nothing to do
Let>fnzOnly=fnOnly
ENDIF

Issue noted. Will be fixed in due course.

Agree, and that should be done for all replace statements where this could happen ...........Wouldn't it be useful if replace 'an empty string' would deliver a defined result like the one you suggest: no change.

Like I said before, this errror takes some time pinpoint the crash location / statement in the script. Or is there a better way then inserting breakpoints?

=== edit
Sorry had not noticed responses 3 and 4. Glad it is on the list of 'will be fixed'.
