Is there anyway to just include a file from a relative path using JUCE? Between graphics, up and down button states, I have about 40 images and trying to create them through the ProJucer causes thousands of lines (over 20,00 in this particular situation) to be generated and embedded in my GUI component. This is causing huge performance issues in Xcode for me. Is it possible to just include the files via relative path and save all that embedded code? The .cpp is so large even GitHub says they are too large to display. Any help is greatly appreciated.
To use embedded images in your project, but not have them taking up space inside each component's .cpp file as generated by the Projucer, do this instead:
Add the image files to the Projucer project itself.
When you save the Projucer project, the image data will be added to your project's BinaryData.h/cpp file that's located in the JuceLibraryCode directory.
When you want to create the ImageButton, instead of selecting 'create a new image resource' (which would put the binary data into your component's source directly), select the BinaryData resource that you created above:

I'm working in MFC (C++11)in VS2015 and I have a set of standalone GUIs that i'd like to use across multiple projects. I know this is possible by creating a .rc file that can be included in the main .rc file of each project based on this:
Using Multiple Resource Files
While conceptually I understand what it is describing, i can't find any example of creating the standalone .rc file and second resource file. I created a test resource header file that lives globally in my solution and tried to include it using Resource Includes, but it can't find it, even with the path. Can anyone point me to links or examples on how to set this up?
I have either .rci files, that are never used with the resource editor. They are used with #include freely.
Or I have special .rc files that contain standard symbols and messages, that are used over a larger set of projects.
I just simply add the second rc file to the project. This resource file is simply #include'ed into the main .rc file of the project.
To prevent errors in the project. This second .rc file is excluded from the build. In the solution explorer right click on the item. And set Exclude from Build to YES.
Take care about collisions of IDs.
Here is how I do it. If you drop the resource you would like to include on the resource folder in the solution explorer, it will show up as a separate and editable resource in your project
You will have to include the headers in your project that go along with them, of course. So watch out for collisions of your IDs. You may have to go to the new resource and use IDs that have been set aside by adjusting _APS_NEXT_XXX_VALUE. I've never used the 'Resources Includes..'. as described in TN035. I just checked and relative paths to bitmaps seems to work fine. Hope that helps.
I know two approaches of doing it. I will demonstrate it assuming you want it for the need of managing the fact your application supports several languages.
The first one is already described by user #xMRi, and depending on your configuration/platform you will include only the .rc in question. For example you have configurations:
en_GB
fr_FR
pt_PT
de_DE
and files
Project_en_GB.rc
Project_fr_FR.rc
Project_pt_PT.rc
Project_de_DE.rc
For getting this right, you will need to do Exclude from build on them all, except on the Configuration you have selected at the moment on the VS Toolbar combo. If you have fr_FR selected, do Exclude from build of all other .rc except Project_fr_FR.rc files and apply the same logic on every configuration.
The other is to have a VS project (vcproj) for each language, where each project contains the .rc file brlonging to it.
The projects
Project_en_GB
Project_fr_FR
Project_pt_PT
Project_de_DE
contain respectively
Project_en_GB.rc
Project_fr_FR.rc
Project_pt_PT.rc
Project_de_DE.rc
Here at work we use both (I never heard of .rci files before; we use the first with normal .rc files), depending on the project.
I recently started working with WxWidgets (2.9.4) and was working through a tutorial I found, but it seems that I'm unable to load any images. I've already properly used the handler (for PNG) and the problem happens at run-time. Below is an image of the popup that is displayed when attempting to run the program.
Here is the code:
wxPNGHandler *handler = new wxPNGHandler;
wxImage::AddHandler(handler);
wxBitmap exit;
exit.LoadFile(wxT("exit.png"), wxBITMAP_TYPE_PNG);
wxToolBar *toolbar = CreateToolBar();
toolbar->AddTool(wxID_EXIT, exit, wxT("Exit"));
toolbar->Realize();
Connect(wxID_EXIT, wxEVT_COMMAND_TOOL_CLICKED, wxCommandEventHandler(mainWindow::exitProg));
Any help is appreciated.
EDIT: I forgot to mention that when I click Cancel, this happens:
I placed the exit.png file in the build directory (/Debug or /Release) as well as the source code directory, but it still has yet to see it.
What is your working directory?
If you are using visual studio and running using the interface ( F5 or ctrl-F5 or the little run button in the toolbar ) then your working directory is the folder containing the project file. So try copying your image file there.
Or open a command window, cd to one of your build directories, and run your app from the command line.
In general, to avoid this sort of problem, I alter the project properties so that the executable is NOT stored in one of the build folders, but in a new folder ( which I usually call 'bin' - my unix roots are showing! ) and also alter the debugging properties so that the working directory is the bin folder.
There are a couple of advantages to this technique:
Both the release and trhe debug version use the same folder, so you only need one copy of any extra file, like your image file.
It is easy to see the executable and extra files in the working directory without being distracted by all the .obj files that end up in the build folders
IMHO this is well worth the little extra trouble in maintaining non default project properties.
First of all, to avoid problems deep inside wxToolBar, always check the return code of LoadFile() or, alternatively, use wxBitmap::IsOk() to check that the bitmap was successfully loaded.
Second, while adding the handler explicitly as you did is perfectly fine, I'd recommend to just call wxInitAllImageHandlers() as it's simpler and has no real drawbacks unless you are looking to create the smallest program possible.
Finally, to address your real problem, the file clearly doesn't exist at the path you're loading it from. You can, of course, solve this by being careful not to change your working directly (or restore it after changing it) in your program and by placing the file in the correct place. But this is, as you discovered, error-prone, so a better idea is to always use full paths to your resources. To construct them, you will find wxStandardPaths useful, in particular its GetResourcesDir() method.
I am working on a small project and I have a file links to download from server. However, instead of downloading the file I want them open in fixed size pop up. I tried facebox but facebox(http://defunkt.io/facebox/) fail to display pdf files and other text files. any one have any idea what I suppose to do in order to accomplish this task.
Thanks you
I need to store a configuration file that can be changed once the executable has been compiled inside of an executable using C++. I assume the configuration file would need to be stored as a resource for it to be editable once the executable has been compiled.
I have no idea how I can go about storing it as a resource and how to then include it in the main section of my project while still leaving it in the resource section.
Any help will be much appreciated.
Windows "*.ini" files is one way.
But, I suggest use XML files for configuration. Most compilers have 2 or 3 libraries to load & store data from XML files.
Besides, they allow to store information in a hierarchical way, and easy to add or remove configuration options.
EDIT:
Another way are JSON files.
I have a problem with my app here. My configuration is as such I can upload a new release and symbolically link it for production -- however, this means every time I upload a new release, all of the photos that were uploaded in any parts of my entire project are wrapped into the old release and disappear.
How can I save these files to a static file location which does not get wrapped in the release? Thanks in advance.
I guess best for this is keeping your media files out of your source project folder, you could eg have a structure like:
myproject
|
|----media
|----src
There's no need to have the media folder in the same directory as your source code, apps etc. So you have a solution where the dir with your release only contains static files! The same applies to the database, if you are using sqlite... Have a look at this for a more detailled structure!
Of course this no must, but experience shows it makes live much easier!
