Basically, I am quite new to autohotkey and was wondering if it was possible to make a script so that when a button is pressed, a file browser pops-up, you then select as many files as you want, but if the size of the file exceeds 1000MB then you cannot select anymore files, after this the files you have are copied to a USB stick in the computer, also, how would i go about making sure the file browser cannot open any files (i.e you cant just right click and click open when browsing for files, you can only select files?
Thankyou,
Ha, I was just looking at that function today!
Take a look at FileGetSize
Here is what is in the docs:
Files of any size are supported, even those over 4 gigabytes, and even
if Units is bytes.
If the target file is a directory, the size will be reported as
whatever the OS believes it to be (probably zero in all cases).
To calculate the size of folder, including all its files, follow this
example:
SetBatchLines, -1 ; Make the operation run at maximum speed.
FolderSize = 0 FileSelectFolder, WhichFolder ; Ask the user to pick a folder.
Loop, %WhichFolder%\*.*, , 1
FolderSize += %A_LoopFileSize%
MsgBox Size of %WhichFolder% is %FolderSize% bytes.
As far as fixing it so the files cannot be opened, well, when you use the FileOpen dialogue (check that out in the docs; it's powerful easy), you can choose exactly what to do with that file.
Basically, you don't "disable" the opening of files, you just do something else instead!
For example, if you run this as a script, it will show the file-browser dialogue, but instead of opening the file in any program, it will run the FileGetSize function on it and then display a messagebox with the file size:
gosub, fileopen
FileOpen:
FileSelectFile, thisfile, 3,startdirectory, Select Files, Any File (*.*; *.gabc)
if(thisfile){
filegetsize, thisfilesize, %thisfile%
msgbox, %thisfilesize%
return
}else{
return
}
return
To get it to work on all the selected files, you'll have to use a loop statement. What I would do is to loop through all the files selected and get their filesize into a variable, and then at the end of the loop, display the messagebox.

I am processing a big images dataset and I'm trying to reorder the files in classes, while at the same time keeping the original directory structure.
To do this, I make a second directory structure with symlinks to the files in the first one.
Everything works as it should but for one small detail: the symlinks created via os.symlink() do not show the image thumbnail, while if I make a link of the same file (e.g., via right click & send to Desktop) I do see the thumbnail.
I wanted to check how the two link files differ (note, the link files themselves, not the linked file), but if I try to drag the os.symlink-generated file in a text editor it opens the linked file instead (while this does not happen with the .lnk file generated via right-click).
What's the difference between the link files? Is os.symlink making something different than a .lnk file? If so, is there a way to get the thumbnail? And if there's no such way, how can I make a .lnk file instead?
Disclaimer: I'm new to using Rumba to access IBM Mainframe.
I have currently set up a library for personal use and I have some code that I want to store in a member of this library, how can I copy/paste from a .txt file on my desktop into this program??? As of right now I can successfully copy/paste one line at a time from documents outside of Rumba.
There are various ways. The best one will depend upon the size of the file/amount of data to be transferred.
If it's only a few lines, block copy and paste should work, but you might have to play with Rumba's 'paste' edit settings such as how to handle new lines, etc.
Bigger files can be transferred with the TSO file transfer program ind£file (maybe ind$file on your system) which essentially copies a file to the screen and then Rumba 'scrapes' the screen for data to put into a file (this is for a mainframe-to-PC transfer; for going the other way the operation is reversed). This can be surprisingly quick.
Lastly there's FTP - either from the command line or via a program such as WinSCP.
Edit:
Based on your comment that the files are about 300 lines long, I'd look into using Rumba's file-transfer option using the ind$file utility. Once you have the files on one system, speak to your mainframe tech support team about the best way to get them to the other systems.
If you need help uploading the files, then the tech support team should be your first point of call.
What mainframe editor are you running? TSO/ISPF?
I copy and and paste from ".txt" files into ISPS all the time with no problem.
Select the text you want to copy (in the ".txt" file)
Press CTRL-C
Open the mainframe file using ISPF Edit (option 2).
Enter line command "Inn" at the line where where you want the copy to start.
(This inserts "nn" empty lines to receive the copied data. Personally, I usually use "nn"=20)
Position your cursor at the first character of the first empty line.
Press CTRL-V
I'm looking for a way to have Excel files in my Matlab folder open 'outside Matlab' (i.e., by MS Excel in most cases) directly by double-clicking the file, rather than right-clicking and selecting 'Open Outside Matlab'.
The .xls files reader built in Matlab can be terribly slow for large files, and an unwanted double-click on a file can cost quite some time in which Matlab is unresponsive.
Thanks.
When you click something in the Current Folder tab, it's actually running the open command, which itself calls finfo to determine what it means by "open" for a given extension. You can see this by creating a breakpoint in open.m directly after the line [~, openAction] = finfo(fullpath); and double clicking - when it hits the breakpoint you'll see it returns openAction as uiimport.
In theory, you can create custom methods for extensions by creating on the path a function openabc where abc is the extension, which should be returned as the openAction.
However, if I look at my finfo.m it first searches for said functions and then regardless of whether or not it finds them if there is an inbuilt method it overwrites them with the standard behaviour. There's even a comment:
% this setup will not allow users to override the default EXTread behavior
If you are willing to muck about in the inbuilts, you may be able to do it like this (backup first! - this could affect other things). I did it temporarily by shadowing the existing finfo like this:
edit finfo.m (Now save a copy to the current folder)
Add these lines after the loop that defines the openAction (in my version, around line 85):
if any(strcmp(['.' ext], matlab.io.internal.xlsreadSupportedExtensions))
openAction = 'winopen';
end
From the folder containing your edited finfo.m, type which finfo -all. You should see two copies, the MATLAB one labelled as shadowed. Opening something from the current folder window should now open Excel externally.
I don't believe there's any straightforward way to do that. It's built in to MATLAB that Excel files will open in the import tool when you double click on them, and there's no way to change that.
You might be able to get around it by changing the file extension on your Excel files to something other than .xls or .xlsx. That would stop MATLAB from opening it in the import tool. Then in Windows, you could associate the new file extension with Excel.
Good day,
I am a CNC program not a computer programer. I am using CAM software to make cutting programs for our CNC router. The router is a bit old and can only take files 200-300 kb big. We are doing carvings that require 1-2 megs text files. I am using a program called GSplit ( http://www.gdgsoft.com/gsplit/ ) to divvy up the text file. It generates 10-25+ files with a custom header that our machine can read. All the files are great and it works, but I have to manually add the closing lines/footer to each file. The files that are created and used are normal .txt files but with a specific extension, .ANC.
Is there any way to automate this process of opening each individual file, scrolling to the end and copy/pasting the same 1-2 lines of code? The files are NAME[number].ANC in a contained folder. Would it be possible to just direct to a folder and say "add this 'text' to every file in this folder"?
Thanks for your time.
What OS are you using? Using Unix you can do a simple script on command line. If you are in the directory with the specific files simply execute:
for file in *; do echo "APPEND THIS" >> $file; done
If you are running Windows you should be able to do the same using cygwin (probably you could also use the power shell, but I don't know anything about the that)
I found a program Notepad++ (apparently the last person to find it...). USed the find/replace files option. A regular expression(note sure exactly what these are but I'm sure you guys do) "\s+\z" as to what to look for. It finds the last space or whatever at the end of all the files and then adds the code I need. Easy, free, and I don't need to write any computer code. Thanks for the attempt to help me Dirkk! :)
I need to insert a generated file into an exe at the time of download. Currently, I create an "empty" file (filled with a repeating character) and package that with the exe. When it comes time to download, I look at the bytes for the installer, find the file by looking for the repeating character, and insert the generated file.
This process however is not working. The repeating character just does not show in the bytes. But I am certain the file is there as it is unpacked if I run the exe. Am I doing something wrong or is inserting a file into an exe even possible?
Also note that I am using Inno Setup Script v5.5.1 to compile the project into an exe.
If you want to change the contents of a file specified in a [Files] entry and compiled into the setup executable, then you must:
Make a dummy file that is at least as large as the largest content you will want to insert.
Fill the file (or at least the first 64 bytes or so) with something unique and easily distinguishable.
Mark its [Files] entry with the "nocompression noencryption dontverifychecksum" flags.
You should then be able to scan the resulting executable for the marker in #2 and then substitute the data that you want. Note however that doing this might invalidate any digital signature on the setup file, although I haven't tested this to be sure.
Note that if the content you are inserting is smaller than the dummy file size, the extra bytes will still remain on the end of your inserted content. So whatever reads the file will have to have some way to ignore that or to recognise the end of the interesting content.
So, if your are making changes in the existing exe file, and if the text is not much, you can probably use some hex editor and make changes at desired location. If text is more , you might want to include some meaningless bytes, just as fillers.
