Enterprise Architect not a valid name

I'm now using Enterprise Architect version 15. Recently, whenever I try to create a new project I got the error show that "Not a valid file name":
Although, my file name is not wrong, I've tried many difference names but it's useless. Now, I just able to open the projects which I've create before.
Can anyone help me how to fix this error.
I've just found the answer. That could be the program's fault.
The issue here isn't the way I named the project. It's because the folder where I decided the project located. The folder is named in Vietnamese (which is allowed in Windows) but I guess EA can't read these character when they get the project located link.
In conclusion, It's better for everyone to name not only the project but also the folder the project located in English to prevent this error
I had the same problem with trying to save the file image. I found that when I originally created the Diagram name I unknowingly pasted in as 2 lines.
Once I fixed it as one line it saved fine.

Scratch: How do I produce an ascii text program listing?

My nine year old son is applying to participate in a programming contest. Any language is allowed, and he wants to use Scratch. But the application requires an ascii text listing of a program to solve a specified preliminary problem. They will not accept a PNG screenshot, or Scratch's binary format. So how does he get an ascii listing of his program? If it is impossible (as I suspect) then I will just read his program and retype it into an ascii editor.
You have a few options here.
If you're using Scratch 1.4, you can save a text-only project summary. Shift-click the File menu, then Write project Summary.
This functionality is coming soon (hopefully) to Scratch 2.0. UPDATE: It has been added.
You can also get a text-based representation of all the blocks using the Scratchblocks generator.
Or, you can save the 2.0 project as myproject.sb2, rename to myproject.zip, unpack the ZIP, and take the project.json file.
Unfortunately, none of these methods can easily be imported back into Scratch.
http://scratchblocks.github.io will convert your project into scratchblocks format. It is exactly what you are looking for.
You can download and edit the json script for the Scratch project. It can then be uploaded to replace the existing project. (This is also a great way to back-up and deploy projects)
From the "See Inside" screen, File->Download to your computer.
Rename the file to have a ".zip" extension instead of just ".sb2".
Unzip the file to edit the "project.json" file.
Edit the json code as desired.
Reassemble the zip file
Remove the ".zip" extension. (Back to ".sb2")
Update the Scratch project by going to the original project and selecting File->Upload from your computer.

Netbeans file cannot be safely opened

I get files from friend who don't use netbeans IDE, when i open file that contain special caracter like 'é','à',... it show me this popup message :
if i say yes it open the file and changes those caracters to '�' like or
Any idea how to open the file safely?
The letters you are mentioning seem to be French. You need to open the file, specifying the original encoding, then save the file as UTF-8
I recently encountered a very similar problem (I have some javascript files in Chinese which translated into similar non-human readable text upon re-opening the file in NetBeans).
My OS: Linux Mint (version 17, Cinnamon; Notepad++ not available and gedit did not solve the problem).
Netbeans Version: 8.0.1
However, I was blessed to have found the history feature! I was able to get a former version of my file restored and backed it up immediately.
To access a file's history simply click on the History button found on the left side of the tool bar between the tabs of open files at the top of the IDE and the actual source code. (You can also right click on the file name and selected History -> Show History). Then Double click on a *Timestamp representing a valid version of your file. Just below the table of Timestamps the old 'backup' file and the current 'corrupted' file should appear side-by-side. (You can preview several historical versions of the file until you find one that works best for you; of course, when choosing a file I suggest one which is still usable and has the most current Timestamp associated with it!) ). Right click again on the 'backup' version of your choice -> Revert from History. Click back on the Source button found right next to the History button.
Finally, to change the default encoding, I applied the fix suggested by Sebas and Danny here:
How to change file encoding in NetBeans?
Please note that the path to the netbeans.conf file is different (at least with version 8.0.1 on my Linux machine). The path on my machine was : ~/netbeans-8.0.1/etc/netbeans.conf.
This saved the day for me and I hope it helps someone else out there! Bonne chance.

Can I search Netbeans' local history?

In one of the previous versions of one of my file in a Netbeans project I wrote code that I later removed, and now I want to retrieve it. However now I can't find it when I manually go to previous versions, as I have many versions in the local history of this file, and I don;t remember when exactly I wrote this code.
Is there a way to run a search on the local history of this file?
I saw in this answer that the local history is kept in this path
<HOME>/.netbeans/<NB_VERSION>/var/filehistory where HOME is my user home and NB_VERSION is the version of NetBeans (e.g. 7.0).
I tried running AgentRansack on that directory, but to no avail.
I recently had to solve this problem and figured it out. Netbeans stores local history files in your user directory as mentioned above. Inside that folder are numbered directories. It's pretty easy to guess which one you need based on the modification date of the folder (if you know when you last looked at it, so that doesn't help you much). In side the numbered folders is another folder with a hashed name, and inside of that folder is a set of files: a data file, and numbered files. The data file can be read with a binary file reader, and if viewed in ascii mode will show the filename that this history belongs to. The numbered files are actually zip files and they have full versions of the file in them. Just unzip those and open with a text editor if they are plain text files.
Hope this helps you out, but I realize its probably too late now. I had to figure this out because I had opened a remote file with netbeans (a file that was not associated with a project), and couldn't get back into the Local History because the file didn't have a project. However I could see it in the Local history by reading the data file, and I just guessed that the other files were zipped by the fact that they started with "PK" in the binary viewer. Once I put it all together I was home free.

Renamed Files Still Exist in Xcode

I'm making an iphone app that displays a random picture chosen from pictures in Resources.
I have renamed some files for categorization,
but running console shows that file with a new name and file with old name both exist as separate files.
Of course, I can't see the file with the old name in my Resource folder, nor in the original folder where the pictures are.
Kinda freaky...
How could I remove the files with old names and make it a norm to not keep another file with the old name whenever I rename a file?
Please help me out.
Thanx.
Expand your Target and remove the images from Copy Bundle Resources.
I'm not sure I understand your question correctly, but I recommend cleaning your targets from the project menu and resetting the simulator.
You can also select all the new files in XCode, right click and select compile.
