Not getting correct path while using browse button to select directory

Given that your explanation of what you wanted was really unclear, I just focused on illustrating how a callback could be used to change the path, not the precise details of what you wanted (since I didn't know that - you just gave one example of the starting path and what the result would be and no indication of the relationship between the code). I'm not writing your code for you - the point is that you can do whatever string substitution you want in the callback, and you can adapt the idea to whatever you need.

Hello Andrew,

i have tried this way -

path_label=hiCreateLabel(
?name 'path_label ?labelText "Path"
?justification 'left)

path_enter=hiCreateStringField(
?name 'path_enter
?defValue "/pkg/power/test/check/thomas"
?callback "MyTrimPathCB(hiGetCurrentForm())"
)

browse_Entry=hiCreateButton(
?name 'browse_nxperc_Entry
?buttonText "Browse..."
?callback "ddsFileBrowseCB(hiGetCurrentForm() 'path_enter \"\" 'directoryOnly)"
)

procedure(MyTrimPathCB(form)unless(boundp('MyInCallback) && MyInCallback
let((pat (MyInCallback t))
pat=pcreCompile("/[^/]*/[^/]*/[^/]*/[^/]*")
form->path_enter->value=strcat("/pkg" pcreReplace(pat form->path_enter->value "" 1)

although from above test script am getting output as /pkg/check/thomas but /pkg is popping in spite when i want field to be empty...

So , my question is there a way i press browse button then only above string manipulation's should be done otherwise not?

Regards,
Thomas

The code above doesn't work because the MyTrimPathCB procedure is scrambled (the unless has no space after the close bracket) and has missing close parentheses, but other than that I think I understand what you're saying (the use model is very odd, so I'm having to guess a bit). You don't want the callback firing if you type in the field, but only if you use the browse button?

If so, you'll have to use something other than ddsFileBrowseCB for the file browser because the callback which updates the path_enter field is built-in and you can't get it to do additional actions. Calling something after the ddsFileBrowseCB won't help because it is non-blocking and returns immediately. The option would be to launch a file browser yourself using hiDisplayFileDIalog and have a callback for that which does the trimming of the path and updating of the field.

Hello Andrew,
exactly ....above seen is happening ...i don't want callback to be fired i.e.("/pkg") if i type other things in field or if i want field to be empty.

Andrew, for removing the starting characters or path am using 

pat=pcreCompile("/[^/]*/[^/]*/[^/]*/[^/]*")

and for removing back characters we use 

pat=pcreCompile("/[^/]*/[^/]*$")

Suppose if i have to remove character's in between … then how should i modify the above line...for eg-
in   "/pkg/thomas/test/cadence/virtuoso/andrew"
i want only  "/pkg/thomas/virtuoso/andrew"     how i can get that?

also can you help me with an example for hiDisplayFileDIalog or any link where i get to understand how to use.

Thanks in advance,

regards,

thomas

Any help/suggestion for above doubts?
