Closing Wordpad via Powershell

funkey_monkey

Hi,

I am working with a script which parses a document and prints its output into a Wordpad file.
I have elaborated on this to allow it to iterate over a number of documents. It all works fine.

I would like to improve on the implementation as there is a flaw in that the original script which I picked up on opens an instance of Wordpad, populates it, but then leaves it open. This is an issue as my modified version of this script can be iterating over hundreds of documents.

pushd %~dp0
...
powershell start wordpad %outputFile%
popd

How do I close each instance of the document?


Thanks.

powershell (get-process wordpad).CloseMainWindow()

Although that won't work if you have unsaved changes in the wordpad document

Thanks - I've almost got it complete now, just need to tidy some parts up.

for /f "delims=" %%x in (C:\Work\tmp.txt) do set docTitle=%%x
                
REM Trim space and parenthesis characters from document title string
echo Document Title is %docTitle%

set docTitle=%docTitle:(=%
set docTitle=%docTitle:)=%
set docTitle=%docTitle:/=%
set docTitle=%docTitle:\=%
set docTitle=%docTitle:-=%
set docTitle=%docTitle: =%

What the above does is it reads tmp.txt into a variable called docTitle. The subsequent steps are to remove characters that cause the filename to be rejected.
Is there any single line command that will remove all non alphanumeric characters from the string. There are some odd ones being returned (y with an umlaut) which I am struggling to remove - they cause the script to fail, so I need to remove them.

Thanks.

Much easier in Powershell

set docTitle='test This!é{}.txt'
for /f "delims=" %a in ('powershell -command "\"%doctitle%\" -replace '[^a-zA-Z0-9\.]',''"') do Set "doctitle=%a"
echo %doctitle%

The last line will print

testThis.txt

Great thanks - I'll try that in the morning.

That seems to be working - thanks.
I'm running it from within a batch file so I had to double up on the % within the for do command.
