Squeak Win 7 Error: No content to install - smalltalk

So I decided to take a look at Smalltalk. Googling led me to Squeak and Squeak By Example. Squeak By Example tells me to drag the .image file onto the Squeak.exe icon. I do this and get an error:
"Error: No content to install"
If I load squeak.exe by itself, no error message occurs. I assume this is because it uses the image file that was included in the download from squeak.org instead of the on I'm trying to use. I've verified that the .image and .changes files are not read only and are unblocked (you know, that little button that exists on the properties dialog of a file that was downloaded from the internet).
Squeak version: Squeak-4.2-All-in-One
SBE: 1.3
What's next?
Edit:
Proceeding with the book a bit, I got to the part where you save the environment, then try to open your recently saved image. I got the same error. So it must be an issue with how I'm opening it, or an permissions thing or something. I made sure both my user and the system user have full control over the image and changes files. I also tried forcing squeak.exe to run as administrator. Still having problems.
Saving the default image while exiting instead of a save-as and simply loading squeak.exe (and the default image) worked without error. I'll look at it some more later.


It seems that when an ImageFile is specified in Squeak.ini (as is the case in Squeak-4.2-All-in-One) that image file is always used. And if you pass a file as an argument to Squeak.exe (or drag and drop it) that file is passed to the image as a source file to be executed instead.
If you want to open an image file by dropping it on the Squeak.exe icon remove the ImageFile directive from Squeak.ini

Vue.js file error "The file will not be displayed in the editor because it is either binary, very large or uses an unsupported text encoding."

I was working on a Vuejs project. So this morning when I opened the project it wasn't compiling anymore and it was reporting an error in one of the components. When opening the component, this message appeared in the VSCode editor "The file will not be displayed in the editor because it is either binary, very large or uses an unsupported text encoding." Clicking on open anyway appears a lot of code with strange symbols as shown in the image. When I try to open the file in another editor, the same problem also happens, but the symbols change. I would like to know what might have happened and if there is a way to recover my file?

Looks like your file is corrupt. Restore from a backup, or re-pull from git.

Embedding an image as a resource in a FireBreath plugin

While using VS (2010), I used to be able to add an image as a resource simply by going to the Resource view and then: Right click project > Add > Resource > Import.
I even asked a question about how to then load it: Loading an image from a resource embedded in a dll, but that changed for some reason.
Now when I try the same thing and save the .rc file, I get this message:
"The resource script FILE_PATH.rc was not created using Microsoft
Visual Studio. Comments, macros, preprocessor directives, and
conditionally included information may be modified and/or removed from
this file during the build process. Replace existing file?"
Even if I click "yes" (in order to just test things) then I get all kind of error messages at compile time:
ResourceCompile:
gen\firebreathWin.rc(8): error RC2144: PRIMARY
LANGUAGE ID not a number
gen\firebreathWin.rc(16): error RC2135: file not found VS_VERSION_INFO
etc...
I have two questions:
What is the correct way to add an image resource which will be added to the compiled plugin using CMake? I searched about it and couldn't find any helping information.
What can be the cause for this change in behavior? since I was able to use the same exact steps before and it worked.
Thanks.

First of all, I wouldn't do this; instead, I'd just put the file in the same directory as your DLL and use the path of DLL to find it.
That said, the "correct" way to do this would be to see what changes are made to the .rc file when you add it in the IDE, copy the .rc file from gen_templates/ in the root of the firebreath directory into your project, and then make those changes to your copy of the file. Any changes you make to the generated file will be overridden any time cmake is run again, which can happen any time your cmake files (CMakeLists.txt, *.cmake) change.

vwnt pop up in smalltalk

When I try to open my smalltalk project file vwnt pops up. The project wont open. I did save the project properly last time I was working on it. Please help if anyone know how to resolve this issue.

what do you mean by smalltalk project files? VisualWorks doesn't have anything like that. What it has is an .im and .cha file. the .im file is the image, which contains VisualWorks and all the changes you did to it. So when you open the .im file, it'll open VisualWorks. You create classes and methods in VisualWorks and by doing so you modify the whole system. When you save the image, the whole VisualWorks system gets persisted and when you open the image file again, the system is restored.
The .cha file is a text file that contains all the changes that you did to the image.

Icon specified in info.plist not found under the top level app wrapper

I'm trying to upload my binary to iTunes Connect using Applicaton Loader. When I select the file and hit send, it sends for about a second and then this error pops up,
Icon specified in the info.plist not found under the top level app wrapper: Default -Landscape#2x~ipad.png
What does this mean? How do I fix it?

Another setting that can cause the issue:
You have to make sure the icon files are also found under build phases/bundle resources

Edit your projects .plist file "as source code" i.e. open it in any old text editor. Then manually edit the icon file names until they make sense.

The .plist is case-sensitive when validated and archived for upload to the App Store.
If you have this in the .plist:
icon-72#2X.png
the file name can not be
icon-72#2x.png
owing to the the case change of the x character .

I rename the file and corresponding change the name of icon file in the info.plist and this solution works for me.

Clean your build
Make sure the file is actually on the file system
Make sure you can see the file in the project navigator.
Most likely step 3 will fail. If so, drag the icon from the finder onto the Project Navigator. When asked, uncheck the "copy ..blabla" option because since the file is already there where you are dragging it to, it would fail. Once the file shows up in the Project Navigator you should be golden.

Also check that you dont have 2 icons with the same name anywhere in your project folders.

I am thinking that the answer to this question will vary in time because Apple constantly changes the application validation rules. These validation rules will surface only when you are submitting your app to the AppStore.
In this particular situation, the validation error happened to me while uploading the app on 08/03/2012.
The solution was fairly straight forward. I had to move to icon files which I had located in a folder nested within the project directory all to way up to the TOP LEVEL project directory - one that has the project file in it. Once I did that and readded the files back to the Resources in my project the validation error went away.
Of course you should check that this issue is not caused by misspelled filenames i.e. differences between your plist file and true names of icon files on your file system.

Another little issue that caught me out was an empty string. I got the cryptic failure message ...
Icon specified in the info.plist not found under the top level app wrapper:
And found this lurking in my plist
<string></string>

I was similar problem's. I have resolve to do this
1/ delete your application Icone in your Target
2/ rename your icone ex: applicationNameSmall.png
3/ add your icone in your application.
This, works for me.

Error is coming up because the App Store is checking names of icon files based upon yourProject-info.plist. If they don't match, error message.
To resolve this issue: Go to yourProject-info.plist in xcode and check BOTH "icon-files" and "icon-files(IOS5)" arrays. You'll want to make sure that each string corresponds with the icon files you have in the file directory.
Change or delete mismatched string names (I had to delete a blank string). Rebuild. As other posters have noted, names are case-sensitive, so be mindful of that too.

Sometimes Icon.png files needs to be open in some image editing tool (e.g Adob Photoshop) and save as a new image. This works fine. Check attached images some times image properties don't change by renaming image file manually.

I had the same issue. I just added the image files it complained about to the project in the viewer. Not sure if that was the right thing to do, but it resolved the issue for me.

I had a silly mistake, in my info.plist the i had Icon.png, and the real file name was icon.png (no uppercase)

Fix the images issues it suggests.
Clean your project.
Build and run to make sure nothing has broken.
Delete the previous archive
Make a new archive (Product -> Archive)
This worked for me. I had to rearchive my application cause the previous one was not updated.

I had the same problem. I gone to Targets->Build Phases and deleted from there old (test) icons which I had pushed early. Good luck:)

How to listen to Screen Captures

Is it possible for me to listen to listen to OSX's built in screencapturing so I can handle the files myself rather than osx doing it?

There are a few options.
Just use Ctrl-Cmd-Shift-3 or 4 instead of Cmd-Shift-3 or 4. This does not save the file to the desktop, instead it saves the data in the clipboard/pasteboard. I don't know where's the official mention of this, but here is one. Then you can get the data through NSPasteboard, see here.
You can use FSEvents to be notified whenever a file is created in a specified folder. Then you can rename the screenshot file soon after it was saved to the desktop by the system. Note that the file name of the screenshot depends on the language environment you choose in System Preferences. So, be very careful if you want to make your program work on a non-English machine.
If you just programmatically take the screenshot, you can use the command line tool screencapture, see the man page.
Of course you can hack into the system and take over the handling of Cmd-Shift-3,4, as Snapz Pro does, for example. You know what you're doing if you choose that way.
