Working with Pure Data, trying to record audio output from a patch I've made, and am 1) unable to create a file within pure data to write to and 2) attempting to use the writesf~ object causes the program to freeze after about two to three seconds. I suspect the two things are related- perhaps the program is attempting to write data somewhere, somehow, but it's going in the wrong place or some such and causing the program to freeze?
I've uninstalled the latest Pure Data release (0.51-1) and installed an earlier stable release (0.5-2) and even tried an alternative called "purr data (latest release)" all with the exact same result on my windows 10 acer laptop: no file created, and program freezes after a few seconds.
I'm testing with this patch:
I first click on the message that reads "open rec.wav" then the start then the stop, and if I take longer than three or so seconds to click on "stop" the program freezes, otherwise nothing at all happens.
I have performed system wide search for the audio file, including the folder that the patch is in, all to no avail.
Any trouble shooting hints will be carefully attempted.
Are you sure you have write-permissions on the target directory?
If your example you use rec.wav which has no explicit target directory (and is just using the "current", so it's hard to tell from outside what this directory would be).
#max-n's answer suggests to use /tmp/foo.wav which is an illegal directory on Windows. Due to a known bug, using an illegal (or otherwise non-writable) path will lock up Pd.
If your "current" directory happens to be your system root (aka C:\), you might well lack the permissions to write there.
You could check by starting the Pd from the cmdline and see whether the terminal spits out any weird errors:
⊞ Win+R
type cmd and hit Enter
in the opening terminal type the full path to your Pd-executable, e.g.:
C:\Program Files\Pd\bin\pd + Enter
(ideally leave out the extension (that is: use .../pd rather than .../pd.exe)
If the problem is indeed a permission problem, you can simply work around it by specifying the full path of the output file (and make sure that it is in a writable directory).
The easiest way to do this is by using a file-selector to choose the output file:
[bang(
|
[savepanel]
|
[open $1(
|
[writesf~]
There might be a reason why the helpfile uses a [delay 1000] to schedule a stop message in a predefined time.

I have a strange problem concerning disk size while using the Dos Dir command in Excel VBA.
I am developing a procedure within which, I need to get a directory listing of a directory with all of it's sub directories, on the same computer and save it to a text file. This piece of code will be run several times by the complete routine. The computer is a generic desktop running Windows 10. Excel is running in the C:, the directory to be listed is in the E: (an internally mounted drive) and the file is being saved to the root directory of the N: (a USB drive).
The format I am running is "Dir/s E:\'Directory Name'\ >>n:\Edir.txt"
When I run this manually in a 'Command Prompt' it works perfectly but when I try to embed it in a 'Shell' command I normally get an error message in the Command Prompt pane saying 'Not enough space on the disk'. and the text file is created but truncated at a random point in the listing.
The code line I am using is '''PID = Shell("cmd /k Dir/s E:\Directory Name\ >>N:\Edir.txt", vbNormalFocus)'''
Each of the disks used has more than 150gb free space and the complete text file comes out at about 3.3mb.
I find this very confusing, each of the drives has plenty of free space and the fact that it works every time when invoked manually and sometimes when invoked from the shell command makes it even more so. Any ideas?

I think I've found the answer, although I'm unclear exactly what the why's and wherefores are. The 'Red Herring' is in the Dos error message "Not enough space on the disk".
It would appear that the real problem is the time taken to process the Dos Dir command. If I put a 10 second delay ( "Application.Wait (Now + TimeValue("0:00:10"))") to give time for the 'Dir' command to complete, it works perfectly. A bit of a nuisance because it slows execution considerably but not a great problem.

I know from experience that if I try to open the same file in Vim in multiple terminals at the same time, I get an error. (Maybe because of temporary files?)
And I know from experience that if I open a text file in Python and read through it, I have to reset the pointer when I'm done.
But I've found that if I run the same Python script in multiple terminals at the same time, I don't get any error; it just successfully runs the script in both. How does this work? Doesn't Python need to read my script from the beginning in order to run it? Is the script copied to a temporary file, or something?
I know from experience that if I try to open the same file in Vim in multiple terminals at the same time, I get an error.
That's not actually true. Vim actually will let you open the same file in multiple terminals at the same time; it's just that it gives you a warning first to let you know that this is happening, so you can abort before you make changes. (It's not safe to modify the file concurrently in two different instances of Vim, because the two instances won't coordinate at all.)
Furthermore, Vim will only give you this warning if you try to open the same file for editing in multiple terminals at the same time. It won't complain if you're just opening the file for reading (using the -R flag).
And I know from experience that if I open a text file in Python and read through it, I have to reset the pointer when I'm done.
That's not exactly true, either. If you make multiple separate calls to open, you'll have multiple separate file objects, and each separately maintains its position in the file. So something like
with open('filename.txt', 'r') as first:
with open('filename.txt', 'r') as second:
print(first.read())
print(second.read())
will print the complete contents of filename.txt twice.
The only reason you'd need to reset the position when you're done reading a file is if you want to use the same file object to read the file again, or if you've opened the file in read/write mode (r+ rather than r) and you now want to switch from reading to writing.
But I've found that if I run the same Python script in multiple terminals at the same time, I don't get any error; it just successfully runs the script in both. How does this work? Doesn't Python need to read my script from the beginning in order to run it? Is the script copied to a temporary file, or something?
As I think should now be clear — there's no problem here. There's no reason that two instances of Python can't both read the same script file at the same time. Linux allows that. (And in fact, if you delete the file, Linux will keep the file on disk until all programs that had it open have either closed it or exited.)
In fact, there's also no reason that two processes can't write to the same file at the same time, though here you have to be very careful to avoid the processes causing problems for each other or corrupting the file.
terminal is just running the command you said it to execute, there is no pointer or anything

I am trying to edit the corflags file so that I can run 32bit applications on a 64 bit pc but everytime I try to edit the file using something like corflags.exe assembly /32bit+ it comes up with the error message cf001 could not open file for writing.
Now I have tried a lot of different options such as:
Running in administrator mode;
Finding the file using a search and checking read only is not ticked
Checking that user full control is ticked
Tried to set the whole folder to non read only
When trying the whole folder, it goes through looking like it has set read-only, but then I click OK and re-right click on the whole folder, the box is filled in (not ticked) does this mean that part of the folder is read only and why does it reset to read only?
I just faced the same problem and have tried the same things.
Run cornflags from an elevated ("Run as administrator") Visual Studio Command Prompt. I did the same for a copy of the original .exe just to make sure no other process was using the program.
Create a copy of the file you intend to target with CorFlags.
(e.g. "WcfServiceHost.exe" --creates--> "WcfServiceHost - Copy.exe")
Rename the original file to something else:
(e.g. "WcfServiceHost.exe" --> "WcfServiceHose_Original.exe")
Rename to copy to the original file name
(e.g. "WcfServiceHose - Copy.exe" --> "WcfServiceHost.exe"
For my purposes, I created copies and named them describing their configuration:
Example:
WCFServiceHost_With32BitOn.exe
WCFServiceHost_With32BitOff.exe
Now I can destroy the WCFServiceHost.exe files and create them from these pre-modified copies. No more CorFlags operations necessary.
Note: this is basically a more verbose version of #RMalke answer and that answer should be marked as the answer.
I realise this is years later, but for anyone else looking, I found that the quickest way was to copy cmd and corflags.exe into the same folder as the one you want to edit. Then run cmd as admin from there.
I am trying to open a downloaded .exe file but it closes as soon as it opens. Is there any possible way so that I can open it for a longer duration to read the content.
It's probably a console application rather than a GUI application. Use the command prompt to run the .exe.
Do the following...
Hold down your Windows key on your keyboard and then tap "R".
This will bring up the Run dialog. Type in "cmd" (without the quotes). Hit enter.
(this will work in all Windows versions - browsing the start menu/screen differs in each version)
If you saved the file to c:\downloads and it's called myFile.exe, type
C:
cd C:\Downloads
myFile.exe
Some of the steps are a bit redundant - if you know what you're doing in the command prompt then skip as needed (but then you probably wouldn't be posting this question). This will work even if you saved the file to D:\downloads.
Another example - if you saved the file to D:\folderA\Folder with a space\ and the file is called "my file with a space.exe" then type
D:
cd "D:\folderA\Folder with a space"
"my file with a space.exe"
If there is an issue (eg it's a 64-bit executable and you're on 32-bit Windows) then you may get a better error message at the command line.
There are so many reasons why the executable does not run. Here are some ways to check what is going wrong:
Is it your .exe? Do you known the "normal" behavior?
When you download it manually, it the result the same?
Do you download the .exe manually or via your application?
Do you see any problem in your Windows Event Viewer?
Is it the same result if you try to download the .exe via different browsers (IE, FF, ...)?
More details are welcome!
The nuget.exe file is not a console GUI application but rather a console package. Once you've downloaded it, you'll want to place it in a folder outside your Downloads folder. For example, C:\NuGet\nuget.exe - then set it as a PATH variable so that it's executable from anywhere.
For no reason that I can see, I can no longer run a TortoiseSVN Update on a development directory on my portable Windows XP Professional SP3 machine, getting the error:
Previous operation has not finished; run 'cleanup' if it was interrupted
Please execute the 'Cleanup' command.
If I try running cleanup, I get another error,
cannot process the following paths: cannot move $ROOT_DIR/.svn/tmp/tmp-... to $ROOT_DIR/path/where/thing/should/go: no such file or directory
I have verified that both files exist, and actually from CMD.EXE prompt I am able to issue a MOVE with those two filenames and have it work correctly. It's no use because next time SVN tries to repeat the operation itself after creating a different tmp file name, and while CMD succeeded, SVN fails.
UPDATE: the path lengths are in both cases well below PATH_MAX, target file system is NTFS, and permissions are OK. Maybe I'll now try with FileMon to see whatever TortoiseSVN is really up to.
I tried downgrading TortoiseSVN but to no avail. Other repositories work OK between the same machines.
TortoiseSVN 1.7.9, Build 23248 - 32 Bit , 2012/08/30 18:25:37
Subversion 1.7.6,

Both server (OpenSuSE Linux 12.2) and client now run the latest version of SVN.
On Windows, I also cannot seem to get any more informative logs or information (I'm not very skilled with TortoiseSVN, I have always used the Linux command line version).
I might delete the local copy and run a checkout, but it's about 2 GB of data, and I'm on a slow connection, so it is really more of a "fly physically to server location and hook a copper Ethernet to the local network there" alternative. I'm reserving that as a sort of last ditch, nuclear option; I'd really rather understand what the problem is, for I fear it might happen again.
UPDATE
I've tried to delete remotely the subdirectory involved, committing the deletion on the server; deleting the subdirectory locally, and emptying the .svn/tmp subdirectory where I found sixteen tmp files, all copies of the one PNG causing problems.
I am still not able to perform any SVN subcommand, getting "Run cleanup!" error; on cleanup; I get a failed attempt to copy a tmpfile to the never-sufficiently-damned .PNG file, which no longer exists anywhere, into a directory that no longer exists anywhere.
I tried recreating the directory locally (but not the file!), no changes.
With FileMon, I traced the source PNG to 8e4c2389cf9d85c8b8ee54d49ea053c752a38187.svn-base in .svn/pristine subdirectory, tried removing it and got SVN complaining. I tried copying it to its intended destination (so that the file-as-it-should-be and the file-as-it-is are identical), no joy.
UPDATE
Well, this is weird. I decided to track everything that TortoiseSVN is doing using FileMon. I could see it checking the wc.db and search the item, checking for it in .svn/pristine (and finding it), copying it (unnecessarily if you ask me...) in .svn/tmp, and finally checking $DESTINATION_FILE (with correct case) using Windows Open() API. And getting PATH NOT FOUND. Yet the file is there, I can see it (and the name is less than 8.3 characters). And why PATH not found and not FILE not found?
Okay, it all boiled down to a directory that had been created remotely with a name ending with space. The file in itself was OK; the directory where it stood was not.
When updating, apparently, the directory got created but the name was shortened by Windows to exclude the final space.
To add to the difficulty of diagnosing, while TortoiseSVN did tell me what the problem was, it did so in the dialog box where the Arial font made the space in \path\to\your \file not clearly recognizable (it was, once I knew where to look, and compared that slash with the others. This one stood a little farther from the letter at its left).
Lesson learned: check really carefully the dialog file name, character by character (note to self: find a way of having it in Courier New if at all possible).
You may have two files in the repository that differ only in case. That's a problem on Windows. See this FAQ for details.
