I want to add a context menu entry with C++. I've been searching but all I can find is some jackass trying to sell me some BS program that does it for me which is not what I am looking for. I'm not looking for anything that uses .NET or Visual C++ either. I want the straight C++ way of doing this.
You can add a right-click menu item that just runs a program, simply by registry editing. No need to do shell extension for that. E.g. I used to have an extract icon thing (copy to clipboard),
HKEY_CLASSES_ROOT\*\shell\copyIcon\=Copy icon to clipboard
HKEY_CLASSES_ROOT\*\shell\copyIcon\command="path to the program" %1
Cheers & hth.,
A decent tutorial, ignore the jackass title, is available here. This kind of shell programming requires COM, no escaping that. Trying to write COM code without MSVC support classes is character-building. But possible, as long as you know COM really well.

I made a simple regex search in Netbeans 7.3 on Windows (using Ctrl+F):
\{\{.*?\}\}
The results get highlighted correctly and the question is - how to extract highlighted text search results? Let it be copying to clipboard, saving as file or whatever else.
Is there any method doing this?
Maybe someone has any suggestion of alternative quick approach to such task in Netbeans? (or other editor)
What OS are you running? If OS X or Linux, read on!
I'm not sure about automatically copying the highlighted results to the clipboard, but I do workaround this quite a bit as well.
The easiest way to accomplish this for me without leaving NetBeans is to simply open a built in terminal window through Window>Output>Terminal (in 7.2.1) - I then navigate to my project, and run the RegEx that I built in the Find feature with my tool of choice. In fact, I use the built in terminal for this type of quick stuff in NetBeans quite a bit. If running Linux, using clipboard tools like xsel (http://linux.die.net/man/1/xsel) in combination with a built in terminal emulator can allow for devising some nice workflow shortcuts within IDEs if you are more comfortable working/coding at a terminal. Note that built in terminal emulators like the one in NetBeans is likely not going to play nicely with cut/copy/paste using the mouse, for various reasons that I won't get in to here.
As far as a built in/extension based solution for something like this, it would be helpful! I am not aware of one.
Hope this workaround helps in the meantime.
I am not new in C++ but this is my first time developing a Win32 program. It has to be graphical and so I have been attempting to get user input using an input/dialog box with no success.
I have read this topic on MSDN and found it helpful, but I get an error about IDD_PASSWORD and IDE_PASSWORD not being defined. Declaring them in resource.h and giving arbitrary values (like 110, 111) yields no results. Other attempts I have tried to modify the auto-generated about box, which also yields no results after modification, I noticed that if i change the value of IDD_ABOUTBOX in resource.h from 103, this also does not work. I also tried using the .rc under Resource View, but still no results.
So I'd like to know if the resource box templates have predefined constant numbers that i have to use, if so where because I searched that too or if there is another way to obtain user input in a windowed application. I just want to obtain an integer, that's all.
There is nothing magic in the numbers assigned to resources. The numbers are what the code actually uses to identify the resources. Visual Studio just allows you to assign symbolic names to those numbers through the use of C macros (i.e., #define) to make your code easier to read. These values are all defined in the file resource.h by convention, and although you can modify that file manually, you usually should not do so—let the Visual Studio Resource Editor handle that for you.
The problem you're running into is that you actually have to create those resources first before the numbers will mean anything. When you create a new Win32 project, Visual Studio will automatically create an about box dialog and give it the symbolic ID IDD_ABOUTBOX. However, there is no such IDD_PASSWORD dialog created by default in a new project, and there isn't one built into Windows.
You can create this dialog yourself using the Dialog Editor (part of Visual Studio's Resource Editor), which is pretty easy to do as it allows you to drag controls around on the dialog where WYSIWYG. When you add a new dialog box to your project's resources, you will be given the option to name it anything you like. You can use IDD_PASSWORD if you want, or any other name. A numeric ID will be assigned automatically based on an algorithm; generally the lowest available number is used.
The article you linked to is assuming that you have already added a dialog to your project with the symbolic name IDD_PASSWORD (which is probably a mistake on the part of the author). All it shows you is how to display that dialog once it exists as part of your project's resources.
It's going to be somewhat difficult to learn Win32 programming just by reading the MSDN documentation. I strongly suggest getting a book that explains it more clearly and in a more logical order. The canonical text is Charles Petzold's Programming Windows, 5th Edition. Note that you will need to make sure you get the 5th edition, as the newer editions digress from their Win32 roots and start talking about completely unrelated things like C# and Silverlight.
If you absolutely must learn by trial-and-error and MSDN, start reading about dialog box resources here.
i am writing (using C++ and GTKmm) a simple photo browser that is available on GitHub:
https://github.com/jjkrol/ZPR
Currently i am working on creating a button, which will allow user to open currently displayed photo in external editor (for example GIMP). Because of this, i have two questions:
Are there any examples of using Gtk::AppChooserDialog class? I couldn't find any and it's hard to start working on choosing the editor without them.
Most important question - i am thinking about a way to launch an application with photo in command line. The only solution that comes to my mind is using system() call to do something like this: system("gimp /path/to/current/photo.jpg"); , but it is probably not the best way of doing this. Anybody knows a better way? I would like to port my application to Windows someday and a more portable way would be great.
Thank you very much in advance.
Instead of system, you might want to use Glib::spawn_command_line_async. There are other similar functions that gives more control if you need it.
For examples, you might want to look the source code of an application like glom.
Thank you very much for answers, gpoo and ergosys! In the end i decided to use Gio::Appinfo as it looks more OOP-like. If anyone would face the same problem - this is what i have end up with:
Glib::RefPtr<Gio::AppInfo> editor = Gio::AppInfo::create_from_commandline("gimp",
"GIMP", Gio::APP_INFO_CREATE_SUPPORTS_URIS);
Glib::RefPtr<Gio::File> photo = Gio::File::create_for_path(
(*currentPhoto)->getPath().string());
editor->launch(photo);
Of course choosing the editor with Gtk::AppChooserDialog is not yet implemented.
I start Microsoft Visual Studio 2010. I chose to start a new project on the Welcome Page. Ofcourse my preferred language is Visual C++ and I'm chosing to begin a Windows Forms Application. I give up a name like Calculator for this one. I do not touch the other options on this dialog. The project gets created and a new Form1.h is automatically added to the project, and a Form1.resX is also added. Because 'Form1' is useless to me, I'dd like to rename it to something more VB6 style, like "frmMain.h". So I right click the Form and simply chose "Rename". After accepting my new name, the necessary changes seem to be occuring. first impression But now, when I try to build this project, It gives a BUILD FAILED. When I look into my files.. Form1 is still mentioned..
So my question is: How do you actually/OFFICIALLY rename Forms?
I've been reading a lot about this and mostly the answer is to delete the form, and re add a new with the right name.. I've heard also that VS asks to rename all references to it, but that doesn't show up to me. Some other people say, you have to use the quick replace function, and rename all references to this class and its file.. This is not a good way to me.. Or is it really the standard procedure?
I have programming experience in C++ and I know about classes and polymorfism and so on. But this is one of the simplest things that keeps me annoying!
You are using VC++.NET to create .NET applications (Windows Form in your case). I must warn you that VS is not very friendly for VC (refactoring, renaming, and little intellisense).
In this case, you renamed the form which will make VS also rename the Form1.resX, but it will not rename the class. It will do it if in C# or VB.NET. Just open the .h file and rename the class itself to match the name of the file.
You also need to update the main .cpp file where "main" resides, and update the Application::Run(gcnew Form1()); in there as well include the "#include".
A solution replace will work (Ctrl+Shift+H), but be careful with this.
click on the form -> properties -> text (usually named as Form1) -> change it.
I have a simple question (that I don't seem to be able to answer),
I am a new VIM/Linux user, and since I do c++ development I decided to install the C.VIM plugin to speed up my development time. The problem is, it says in the plug-in (c++) menu that to do a switch statement I have to write \ss (for me the leader is ",", so it's ",ss") but when I do this it just puts me in insert mode and nothing happens. I know the plugin is well set up because when I open a new c++ file it generates a comment box where I can give the description of the program.
I would love it if I would be able to use the shortcuts, because using the menu just losses the point of using vim.
Oh and please, just keep in mind that I am new to vim, I still have hard time figuring out what means <c-r> + TAB (which is, if i'm not mistaking "ctrl-r <tab>"), so if you could just try to explain the solution clearly without to much jargon I would appreciate it. (while i'm here, does anyone know of a good vim tutorial where I could understands all of the vim jargon, thanks!)
I appreciate all the help.
I use this cheat sheet:

Please add the below line to .vimrc and
helptags ~/.vim/bundle/c.vim/doc
Note: I have pointed to my c.vim doc and I use bundle, it may differ for you :)
