filename change and extraxct 5 char from name

Post by worldwide » Tue Jul 24, 2007 12:30 pm

Hello

new topic .... and im gettin or better to say im already addicted to MS

I have a file, it has a filename like asdf_xxxx_assd.DAT
And the x can change from 4 till 8 times x, like : asdf_xxxxxxxx_assd.DAT

I have another file, this one i want to rename into xref_xxxxx.DAT, where the xxxxx is the one from the otherfile.

Is this possible ?

I checked out Position, Length and so on, but since the amount of x changes im stuck at the moment.

Any help or tipps ?

Thanx in advance

This is the long-winded, but probably easier to understand, method:

Code: Select all

//play around with different values between the underscores
Let>fname=asdf_123456_assd.DAT

//extract the part between the underscores (_)
Position>_,fname,1,start
Let>start=start+1
Length>fname,lf
MidStr>fname,start,lf,temp
Position>_,temp,1,end
Let>end=end-1
MidStr>temp,1,end,midPart

Let>newfile=xref_%midPart%.DAT
MessageModal>newfile

//RenameFile>sourcefile,newfile
Change the value of fname and it will always extract the part between the underscores.

If it's guaranteed that those are the only two underscores in the filename, then it's simpler to use Separate>

Let>fname=asdf_123456_assd.DAT
Separate>fname,_,parts
Let>newfile=xref_%parts_2%.DAT
MessageModal>newfile

This is what i finished, the only thing is maybe that if there are more DAT files in the directory, but it still works :-) ;-)


---------------------------------------------------------------------------------
---------------------------------------------------------------------------------

GetFileList>c:\directory\*.DAT,aantal,;

Let>fname=%aantal%

//extract the part between the underscores (_)
Position>_,fname,1,start
Let>start=start+1
Length>fname,lf
MidStr>fname,start,lf,temp
Position>.,temp,1,end
Let>end=end-1
MidStr>temp,1,end,midPart

Let>newfile=XREF_%midPart%.DAT

RenameFile>c:\directory\XREF.DAT,c:\directory\%newfile%
-----------------------------------------------------------------------------
-----------------------------------------------------------------------------


Thanx again for the help :-) ;-)

I'm confused, which part do you want to re-use, 'xxxx', 1, or 'xxxxx' ?

Those would be parts_1, parts_2, but then you would need to Separate> again on '.' to get the 'xxxxx' without the .DAT

Ok,

now it doesnt work so well as i thought......

this is the error...

i have 5 files with different start names but the same ID(but the ID ispossible from 3 till 8)
Like :

abc_ID1_ID2.dat
def_ID1_ID2.dat
ghi_ID1_ID2.dat
jkl_ID1_ID2.dat
mno_ID1_ID2.dat
XREF.dat

I want to rename that XREF.dat into XREF_ID1_ID2.dat

What i tried was to get the first file, takeout the ID1 and ID2.
I did that with :
---------------------------------------------------------------------------------

GetFileList>c:\directory\*.DAT,aantal,;
Let>fname=%aantal%
Position>_,fname,1,start
Let>start=start+1
Length>fname,lf
MidStr>fname,start,lf,temp
Position>.,temp,1,end
Let>end=end-1
MidStr>temp,1,end,midPart
Let>newfile=XREF_%midPart%.DAT
RenameFile>c:\directory\XREF.DAT,c:\directory\%newfile%
-----------------------------------------------------------------------------
But ... as MS it works somehow, but if i compile it into an exe it gives an error

As you maybe can think im a beginner, so my "coding" if you can speak of it is more the less very basic, but im triing ;-)

Maybe some thoughts ?

Ok, now i got a solution, but also a problem :

I did it now different, i did a readout of the file and the proper position.
I got the info i needed.
--------------------------------------------------------------------
--------------------------------------------------------------------
ReadLn>C:\directory\XREF.DAT,3,text
MidStr>text,69,11,show
Let>rest=show
//MessageModal>show
Position>\,rest,1,start
Let>start=start+1
Length>rest,lf
MidStr>rest,start,lf,temp
Position>.,temp,1,end
Let>end=end-1
MidStr>temp,1,end,midPart
Let>newfile=%midPart%
//MessageModal>newfile
RenameFile>C:\directory\XREF.DAT,C:\directory\XREF_1_%newfile%.DAT
---------------------------------------------------------------------
---------------------------------------------------------------------

As a macro i works, but as soon as i convert it into an exe-file it doesnt work, could someone help me why this is ?
Aspecially the rename function doesnt work !!
