I want to ask from users to load an excel file as an input data. this process must be done by opening a browsing window to select excel file.
what can I do?
You can use open_dialog_native from Gtk.jl.
julia> open_dialog_native("Choose the input Excel file", GtkNullContainer(), ("*.xlsx",))
"/path/to/myfile.xlsx"
It opens the file chooser interface appropriate to the user's OS, and once the file is chosen, returns the chosen file's full path as a string.
The ("*.xlsx",) is a tuple that constrains what type of files are shown by default in the file chooser. (The GtkNullContainer() argument just specifies that you're not running this as part of an existing GTK app.)

I saved the data in txt file. Everything is ok. Now, I want to show the data on the chart then that data send by email.
First, I select the txt file from the dialog and then show it on the chart or graph which is ok till here. Then, I want to attach that file automatically and after 5 sec sends it to a specific email. my problem is that I don't want to create a control for attach to choose the txt file, I want to select once the file , then read, then that file email.
Normally, I must select once to read and another time again to select that file (2 times) but I want to select one time the txt file then read and after 5 sec that file attaches and email. I cannot connect attach file wire (RED Wire) to the file dialog because the type of attach is 1D array file path and the type of file dialog is path, I don't know what should I do.
Thanks for helping me.
Use Build Array function to convert your single path (which goes from path select dialog) to 1D array of paths.
I'm trying to build a program that gets users name at first. This user names are kept in a text file. After user logins, according to the user's name, I want user to be lead his/her specific informations. I figured out that I can only do it with a file that is created when he sign up for an account which I direct him with my sign up button in Livecode. While he/she create his account I want to create a specific file for his/her. Can you help me with it please?
PS: I don't want to do it with a database right now. I just want to learn how to create a file without a specific name like
put specialFolderPath("documents")&"/userLoginCridentials.txt" into tFile put URL("file:"&tFile) into myFile
Instead of this "userCridentials.txt" I want something user can create with his own name :)
Having a little problem to understand your question. Are you targeting mobile or desktop? Are you having problem saving or reading the data?
If saving is you problem
On desktop you can use:
ask file "Save file as:"
then you get the filename back in it so you can use:
if it is not empty then
# We have a complete file path in 'it'
put it into tFile
put tData into url ("file:" & tFile)
end if
If you targeting mobile and would like to save into the specialFolderPath("Documents")you can get the filename from a field and then save to that file. E.g. if you have a field named 'fileName' you can use something like:
put tData into url("file:" & specialFolderPath("Documents") & "/" & field "fileName"
Of course you should do some error checking to ensure that a user don't overwrite existing files without at least asking for permission, etc.
You can of course use a variable instead of a field...
If reading data is your problem
On desktop you can use:
answer file "Open File:"
Same as above but you now read data instead:
if it is not empty then
# We have a complete file path in 'it'
put it into tFile
put url ("file:" & tFile) into tData
end if
on mobile you probably would like to present a list with the user-created files. In LiveCode you can list all files in the defaultFolder with the files. But you must set the defaultFolder to the folder you want to list.
set the defaultFolder to specialFolderPath("Documents")
put the files into tFiles
Now tFiles contains every file in that folder and you can filter it, display it in a list etc. E.g:
filter tFiles with "*.txt"
put tFiles into
If your problem is how to remember the "current" file name
Whenever you restart your app every variable is reset. So everything you want to remember between runs needs to be saved before your app quits. And for that you need a predefined filename. SO then your procedure will be:
Read in the predefined file.
Grab the file name from within that file
Read the file
If your problem is something else
Sorry, then I misunderstood your question...
I am working on developing an expert system using CLIPS. For the case at hand I need to read data from a excel file. How do I do that? Or what solutions do you propose? Thank you in advance.
You can use the open command to open a file for reading in either text or binary mode. If you opened a xlsx file in binary mode, you could use the get-char function to retrieve individual characters from the file. There's no built-in functionality for parsing a xlsx file, so you'd have to add code to do the parsing and create appropriate CLIPS values from the data. If possible, it would be easier to save your excel file as tab-delimited text. If each cell is a valid CLIPS token, then you can use the read function to retrieve the cell values. If each cell is not a valid CLIPS token (for example, a cell representing a string that has spaces but lacks quotation marks at the beginning and end), then you need to use the readline function to grab an entire row of data and then use some of the string functions to locate the tabs and split the string into valid tokens.
Stack!
I'm currently trying to code a neat little function in Visual Basic that deletes my entire file system for my program depending on the contents of one text file.
If my text file contains the number 0 by itself, my file system will be deleted. If it contains a 1 by itself, it will not delete the file system and carry on with its pathway of execution.
the problem I'm having is reading the file, then assigning the text file's contents to a variable (string), which then is used in an if statement to decide whether it deletes (then immediately recreates) the file system, or keeps it. Ideally I'd be using this primarily for when the user installs. By default, it is set to 0 so that it clears any stored content, then after creating my directory, the number turns to 1 so that it does not reset my programs content directory.
Here's my code. The first line is giving me difficulties -
Could not find file 'C:\Users\110fa_000\documents\visual studio 2013\Projects\Novation_Launchpad_Emulator\Novation_Launchpad_Emulator\bin\Debug\0'.
fileReader = File.ReadAllText(My.Resources.FirstTimeUse)
If fileReader = "0" Then
FirstTimeUse = True
End If
If you can help me, that'd be absolutely brilliant. I don't think there's any more information I can give sadly, but everything regarding the function, purpose, and error is there.
I have used the "Hex Editor to modify DPB to DPx" many times in the past to bypass VBA project security on my old Excel VBA projects (.xls), so I definitely know how to do it and know that I can do it.
However I have just tried to do it yesterday and found that it no longer seems to work. I tried using both Excel 2011 (Mac) and Excel 2003 (Windows) and in both cases, I got the same behaviour;
Opening the VBA editor gave a message saying that the project is corrupted and that the project will be removed. The VBA editor then opens and, sure enough, all VBA is stripped out from modules and worksheets.
I have tried this method:
Is there a way to crack the password on an Excel VBA Project? (ie. creating a spreadsheet with a known password and then copying across the relevant fields)
But find that the length of the "GC" key created on my 'dummy' spreadsheet is shorter than the "GC" key on the spreadsheet that I am wishing to access (the "target"). I had read elsewhere that in cases where the "target" keys were longer, you could pad the "dummy" keys to the same length but there is nothing i can find to say what to do in the reverse case.
So - my questions (s);
Is anyone aware if a patch has been applied that makes the "hex editor" approach invalid?
Can anyone help with what to do when the dummy keys are longer than the target keys?
Can anyone else provide any updated onsite into this issue?
EDIT
Having now solved this (to some degree) i thought i'd add a summary here.
I HAVE NOT been able to get this to work on Mac Excel 2011. Something about changing the file from filname.xlsm to fielname.zip and back again results in a corrupted excel file which Excel 2011 refuses to recognise.
I DID manage to get this to work on an old windows machine (XP/Excel 2007) by modifying the .xlsm file name to .zip, editing the DPB= AND GC= values in the vbaproject.bin file with a hex editor then saving this in the .zip file before renaming the .zip back to xlsm. I used the "test" example given by Ricko at the bottom and it worked with ONE CAVEAT - i had to 'pad' out my GC value to make it that same length as the original one in my file.
ORIGINAL: GC="0F0DA36FAF938494849484"
NEW: (TEST) GC="BAB816BBF4BCF4BCF4" (from Ricko below)
NEW: (TEST) GC="BAB816BBF4BCF4BCF40000" (what i used and what worked)
I have your answer, as I just had the same problem today:
Someone made a working vba code that changes the vba protection password to "macro", for all excel files, including .xlsm (2007+ versions). You can see how it works by browsing his code.
This is the guy's blog: http://lbeliarl.blogspot.com/2014/03/excel-removing-password-from-vba.html
Here's the file that does the work: https://docs.google.com/file/d/0B6sFi5sSqEKbLUIwUTVhY3lWZE0/edit
Pasted from a previous post from his blog:
For Excel 2007/2010 (.xlsm) files do following steps:
Create a new .xlsm file.
In the VBA part, set a simple password (for instance 'macro').
Save the file and exit.
Change file extention to '.zip', open it by any archiver program.
Find the file: 'vbaProject.bin' (in 'xl' folder).
Extract it from archive.
Open the file you just extracted with a hex editor.
Find and copy the value from parameter DPB (value in quotation mark), example:
DPB="282A84CBA1CBA1345FCCB154E20721DE77F7D2378D0EAC90427A22021A46E9CE6F17188A". (This value generated for 'macro' password. You can use this DPB value to skip steps 1-8)
Do steps 4-7 for file with unknown password (file you want to unlock).
Change DBP value in this file on value that you have copied in step 8.
If copied value is shorter than in encrypted file you should populate missing characters with 0 (zero). If value is longer - that is not a problem (paste it as is).
Save the 'vbaProject.bin' file and exit from hex editor.
Replace existing 'vbaProject.bin' file with modified one.
Change extention from '.zip' back to '.xlsm'
Now, open the excel file you need to see the VBA code in. The password for the VBA code
will simply be macro (as in the example I'm showing here).
New version, now you also have the GC=
try to replace both DPB and GC with those
DPB="DBD9775A4B774B77B4894C77DFE8FE6D2CCEB951E8045C2AB7CA507D8F3AC7E3A7F59012A2"
GC="BAB816BBF4BCF4BCF4"
password will be "test"
Open xls file with a hex editor.
Search for DPB
Replace DPB to DPx
Save file.
Open file in Excel.
Click "Yes" if you get any message box.
Set new password from VBA Project Properties.
Close and open again file, then type your new password to unprotect.

If you deal with .xlsm file instead of .xls you can use the old method. I was trying to modify vbaProject.bin in .xlsm several times using DBP->DBx method by it didn't work, also changing value of DBP didn't. So I was very suprised that following worked :
1. Save .xlsm as .xls.
2. Use DBP->DBx method on .xls.
3. Unfortunately some erros may occur when using modified .xls file, I had to save .xls as .xlsx and add modules, then save as .xlsm.
