I need to get a filename of the own installation package within an InstallScript function. How can I do that?
SETUPEXEDIR and SETUPEXENAME are MSI properties. You can obtain their values through the MsiGetProperty function. If you are not using an MSI then you can use the PACKAGE_LOCATION system variable, as in
ParsePath(svSetupExeFileName, PACKAGE_LOCATION, FILENAME);
I have found a way to get the filename:
function ShowInstallerFilename(hMSI)
NUMBER maxPath;
STRING originalDatabase;
begin
maxPath = MAX_PATH;
if(MsiGetProperty(hMSI, "OriginalDatabase", originalDatabase, maxPath) == ERROR_SUCCESS) then
SprintfBox(INFORMATION, "Deferred Execution", "Original database is %s", originalDatabase);
endif;
MessageBox("Done", INFORMATION);
end;

I'm trying to retrieve raw physiological data (hand dynanometer) from Acqknowledge to be able to preprocess and analyze them in R (or Matlab) in an automatized way. Is there a way to do that ? I would like to avoid having to copy/paste the data manually from Acknowledge to Excel to read them in R.
Then I would like to apply a filter on the data and retrieve the squeezes of interest in R. Is there a way to do that ?
Any advice is very welcome, thank you in advance!
I had a similar problem. The key is the load_acq.m function, you can find it here -> https://github.com/munoztd0/fusy-octave-memories/blob/main/load_acq.m then you can just loop through them and save them as .csv or anything that you can load and work with in R.
As for how to do that I have put together a little routine to do that.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% Create physiological files from AcqKnowledge
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% SETTING THE PATH
path = 'your path here'; %your path here
physiodir = fullfile(path, '/SOURCE/physio');
outdir = fullfile(path, '/DERIVATIVES/physio');
session = "first" %your session
base = [path 'sub-**_ses-' session '*'];
subj = dir(base); %check all matching subject for this session
addpath([path '/functions']) % load aknowledge functions
%check here https://github.com/munoztd0/fusy-octave-memories/blob/main/load_acq.m
for i=1:length(subj)
cd (physiodir) %go to the folder
subjO = char(subj(i).name);
subjX = subjO(end-3:end); %remove .mat extension
filename = [subjX '.acq']; %add .acq extension
disp (['****** PARTICIPANT: ' subjX ' **** session ' session ' ****' ]);
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% OPEN FILE
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
physio = load_acq(filename); %load and transform acknowledge file
data = physio.data; %or whatever the name is
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% CREATE AND SAVE THE CHANNEL
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
cd (outdir) %go to the folder
% save the data as a file text in the participant directory
fid = fopen([subjX ',txt'],'wt');
for ii = 1:length(data)
fprintf(fid,'%g\t',data(ii));
fprintf(fid,'\n');
end
fclose(fid);
end
Hope it helps !
I am using Octave 5.1.0 on Windows 10 (x64). I am parsing a series of directories looking for an Excel spreadsheet in each directory with "logbook" in its filename. The problem is these files are created by hand and the filenaming isn't consistent: sometimes it's "LogBook", other times it's "logbook", etc...
It looks like the string passed as input to the dir function is case-sensitive so if I don't have the correct case, dir returns an empty struct. Currently, I am using the following workaround, but I wondered if there was a better way of doing this (for a start I haven't captured all possible upper/lower case combinations):
logbook = dir('*LogBook.xls*');
if isempty(logbook)
logbook = dir('*logbook.xls*');
if isempty(logbook)
logbook = dir('*Logbook.xls*');
if isempty(logbook)
logbook = dir('*logBook.xls*');
if isempty(logbook)
error(['Could not find logbook spreadsheet in ' dir_name '.'])
end
end
end
end
You need to get the list of filenames (either via readdir, dir, ls), and then search for the string in that list. If you use readdir, it can be done like this:
[files, err, msg] = readdir ('.'); # read current directory
if (err != 0)
error ("failed to readdir (error code %d): %s", msg);
endif
logbook_indices = find (cellfun (#any, regexpi (files, 'logbook'));
logbook_filenames = files(logbook_indices);
A much less standard approach could be:
glob ('*[lL][oO][gG][bB][oO][kK]*')
I'm trying to use SQLitePCL package to develop a simple UWP app that executes database commands (create-select-update-delete). I created a database sql file that contains some sqlite commands and I'm trying to execute them in my code:
Uri appUri = new Uri("ms-appx:///Assets/db.sql");
StorageFile sFile = StorageFile.GetFileFromApplicationUriAsync(appUri).AsTask().ConfigureAwait(false).GetAwaiter().GetResult();
string sSQL = FileIO.ReadTextAsync(sFile).AsTask().ConfigureAwait(false).GetAwaiter().GetResult();
ISQLiteStatement cnStatement = dbConnection.Prepare(sSQL);
cnStatement.Step();
But when I run the program, it only executes the first statement in the sql file which is CREATE command and exit without executing the rest of the commands. Here is the sample content of the sql file:
CREATE TABLE Superhero (
Type TEXT PRIMARY KEY,
Picture TEXT
);
INSERT INTO Superhero (
Type,
Picture
)
VALUES (
'batman',
'batman.ico'
);
Anyone knows if there is a way in SQLitePCL to execute a sql file?
Any help would be very much appreciated!
Thanks!
According to the description of sqlite3_prepare interface:
These routines only compile the first statement in zSql, so *pzTail is left pointing to what remains uncompiled.
So that it seems like only the first statement in the commands is actually executed. The remainder is silently ignored. Since every command is ended up with symbol ";", for a quick and simple solution, you may just split the sql commands into single statements and then execute one by one. For example:
string sSQL = FileIO.ReadTextAsync(sFile).AsTask().ConfigureAwait(false).GetAwaiter().GetResult();
var dbConnection = new SQLiteConnection("sun.db", SQLiteOpen.READWRITE);
//using (ISQLiteStatement cnStatement = dbConnection.Prepare(sSQL))
//{
// var result = cnStatement.Step();
//}
var statements = sSQL.Split(new[] { ';' });
foreach (string onestate in statements)
{
using (ISQLiteStatement cnStatement = dbConnection.Prepare(onestate))
{
var result = cnStatement.Step();
}
}
Otherwise, you may need to update the SQLitePCL Nuget package.
We know U-SQL supports directory and filename pattern matching while extracting the files. What I wanted to know does it support pattern matching based on date of creation of the file in ADLS (without implementing custom extractors).
Say a folder contains files created across months (filenames don't have date as part of the filename), is there a way to pull only files of a particular month.
The U-SQL EXTRACT operator is not aware of any metadata (such as create date) about a file - only the filename.
You could probably build a solution using the .NET SDK. For something rather simple you could use PowerShell to create a file which will contain all the files that meet your date time criteria. Then consume the content as desired.

Currently there is no way to access or use file meta data properties. Please add your vote and use case to the following feedback item: https://feedback.azure.com/forums/327234-data-lake/suggestions/10948392-support-functionality-to-handle-file-properties-fr
it's been a while since this question was asked, and I'm not sure if this is what you were looking for originally, but now you can use the FILE.MODIFIED U-SQL function:
DECLARE #watermark string = "2018-08-16T18:12:03";
SET ##FeaturePreviews="InputFileGrouping:on";
DECLARE #file_set_path string = "adl://adls.azuredatalakestore.net/stage/InputSample.tsv";
#input =
EXTRACT [columnA] int?,
[columnB] string
FROM #file_set_path
USING Extractors.Tsv(skipFirstNRows : 1, silent : true);
#result =
SELECT *, FILE.MODIFIED(#file_set_path) AS FileModifiedDate
FROM #input
WHERE FILE.MODIFIED(#file_set_path) > DateTime.ParseExact(#watermark, "yyyy-MM-ddTHH:mm:ss", NULL);
OUTPUT #result TO "adl://ADLS.azuredatalakestore.net/stage/OutputSample.tsv" USING Outputters.Tsv(outputHeader:true);

I need to isolate the file extension from a path in SQLite. I've read the post here (SQLite: How to select part of string?), which gets 99% there.
However, the solution:
select distinct replace(column_name, rtrim(column_name, replace(column_name, '.', '' ) ), '') from table_name;
fails if a file has no extension (i.e. no '.' in the filename), for which it should return an empty string. Is there any way to trap this please?
Note the filename in this context is the bit after the final '\'- it shouldn't be searching for'.'s in the full path, as it does at moment too.
I think it should be possible to do it using further nested rtrims and replaces.
Thanks. Yes, you can do it like this:
1) create a scalar function called "extension" in QtScript in SQLiteStudio
2) The code is as follows:
if ( arguments[0].substring(arguments[0].lastIndexOf('\u005C')).lastIndexOf('.') == -1 )
{
return ("");
}
else
{
return arguments[0].substring(arguments[0].lastIndexOf('.'));
}
3) Then, in the SQL query editor you can use
select distinct extension(PATH) from DATA
... to itemise the distinct file extensions from the column called PATH in the table called DATA.
Note that the PATH field must contain a backslash ('\') in this implementation - i.e. it must be a full path.
