A process of mine opens a HML file, modifies it and then saves, closes it.
I then need to run an.exe that opens this file right after this.. However, nothing that I find on this forum works that supposedly tests to see if the fie is still open, ready to be used by another process.
Right now, I just Sleep(2000) .
I would like something cleaner than this.
This function, for example, returns False when nothing has it opened or if I open the file with notepad or any other editor.
I am running on a win7 laptop, if that has any bearing.

Computer Plucker is a fork and a "restoration" of Computer stats utility by @Rogue5099 (link)
You can obtain various data about local machine, as from the screenshot.

But my goal is not (only) to provide another PC stats tool, but to develop a very basic remote inventory tool, like (a small subset of) the abandoned Spiceworks or the Microsoft SCCM.
So this script can be deployed on a machine as a standalone executable (yes you need only ONE file to distribute) , and launching the .EXE it installs itself to a folder (es. c:\autoit\computerplucker)
In tools menù you can set two tasks and not only
one for creating every week a file.ini with all the data of the machine. another one  for creating every week a file.ini with all the data of the machine PLUS uploading a CRYPTED record of the machine in a free mysql DB online For my needs, I am  deploying the .exe and schedule the second task, uploading data one time a week.
In tools menù you will find also commands for:
manual creating the .ini data file  to upload the data in crypted records to upload the data in clear text records (for testing..) total uninstall of ComputerPlucker, with a simple security code. many other tasks in not so logical order.. next version I have to tidy the menù... So my plan is to deploy this on my machines, and have the data in a online DB, this DB will be for me only a "cache" for data records to be downloaded (and deleted) by another script.
As today the account of this TEST DB is embedded in code, using the "File to Base64 String' Code Generator" by @UEZ (used also for embedding icons and XML task definitions)
    Local $mysqlhost = "sql11.freemysqlhosting.net"
    Local $mysqlport = "3306"
    Local $mysqldb = "sql11403701"
    Local $mysqluser = "sql11403701"
    Local $mysqlpsw = "QtL7T9U5GV"
The DB is one table of 30 mysql tinytext fields... very simple indeed...
You can try to upload data to this DB and access (phpmyadmin or a random mysql browser app) to see the results.
Or you can use my ComputerPluckerDBbrowser (see at the end of this post) a script to collect and manage the data.

PRIVACY warning: you are uploading data of your PC account and PC data, test as your risk (or test in another account...)
 
I also created a small post in a blog for not so geek friends, and I have a more advanced version of the data browser, you can have more info lookin' here. 😀
Attached you will find the code, and all the necessary includes are at this >link<.

$input = $CmdLine[1] $bytes = 1000000 ; 1000000 for 1 MB, 1000 for 1 KB $size = FileGetSize($input) $file = fileopen($input, 16) $max = ceiling($size / $bytes) for $i = 1 to $max $data = fileread($file, $bytes) $output = $input & '_' & $i & 'of' & $max filewrite($output, $data) next ^file split
file path for a 20MB "video.mp4" is input, it will be output as "video.mp4_1of20", "video.mp4_2of20", etc. change $bytes to affect the split files size, this example made them 1MB (10^6 bytes)
 
$input = $CmdLine[1] $name = stringtrimright($input, 1 + stringlen($input) - stringinstr($input, '_', 0, -1)) $split = stringsplit($input, 'of', 3) $max = $split[ubound($split) - 1] for $i = 1 to $max $in = $name & '_' & $i & 'of' & $max $file = fileopen($in, 16) $data = fileread($file) fileclose($file) filedelete($in) filewrite($name, $data) next ^ file join
file path for any of the "video.mp4_Xof20" segments is input. the "video.mp4_Xof20" segments are read and written to "video.mp4" and then deleted, leaving the newly joined "video.mp4" in the end
 
i made this today because i had a big file that i couldn't really open. i split it into 1000 chunks to make processing and stuff easier. i've also used it to split files to just under 25MB segments so i can attach and mail big files over gmail which is silly but it worked

I like and have been using TeraCopy, a third party program, for many years. Mostly it is a great program, but it does have some issues. On Windows XP for instance, Thumbs.db files could often hold up a copy or move process until the user manually responded to the error prompt. Some other issues I discuss below.
PLEASE NOTE - I am not related to or affiliated in any way with the 3rd party TeraCopy program developers.
ALSO NOTE - I myself have only tested TeraCopy Cure at this point, on Windows 7 (32 bit), and only with the free version of TeraCopy 2.27.
This program, TeraCopy Cure, is related to another one of my TeraCopy assistant programs, TeraCopy Timer, but aims at being simpler and quicker to use ... if lacking its more advanced features.
TeraCopy Cure is a frontend for TeraCopy and sets out to make up for its flaws and limitations.
One of those flaws is queuing order, and the limitation relates to a same destination issue.
You would think that queue order would be the same as add order, but that is not the case, and if you are doing a mix of COPY and MOVE then the COPY process could easily fail. It could fail with some source items, even if the  COPY process has already started before the same source MOVE process begins ... especially if the destination folder is on the source drive ... only the currently copying file is locked to that process.
If you drag and drop another source for a same destination as an existing or impending COPY or MOVE process, then usually TeraCopy nicely adds it for you to that existing job. However, you might wish to avoid that, or it might occur during the testing phase of that active process, and then not be properly processed etc. But you are not given a choice and it just gets added.
 
     
HOW TO USE
See the right-click menu of the 'Batch List' (lowest field) and the right-click menu of the Tree field, for some useful options.
(1) If desired, enable 'Auto Start'. NOTE - Even if enabled, this can be bypassed.
(2) Set the destination folder, either by browsing on the tree or by dragging a folder to the Destination input field or label. Right-clicking on a folder in Explorer will also work, if enabled. The destination folder path will also show in the Tree if that right-click option is enabled.
(3) Then drag & drop source file or folder onto one of three five areas - Folder (Drive) Tree field, or COPY or MOVE buttons ... this now also includes the source input and label.
NOTE - If the Folder (Drive) Tree field is used, then you will additionally need to click either the COPY or MOVE button, to have that job added to the Batch List ... but this avoids 'Auto Start' if it is enabled. Drag & dropping to the buttons instead, saves on clicking, but starts the first job etc immediately if 'Auto Start' is enabled.
(4) If needed and ready, click the START button to run the first job and those that follow.
More information is included in program and in the NOTES etc sections below.
   
WARNING - Depending on the amount of content on your destination drive, and folder level depth, and the speed of your PC, display of the full path in the Folder (Drive) Tree can take a while to show ... if you have that (right-click) option enabled ... it isn't by default. I found this feature quite tricky to get right, and I'm still not 100% sure it is now full-proof.
