Is it possible to open files in Emacs in way that Sublime Text 2 does (Cmd+P or Ctrl+P)?
I miss this feature so much.
Have you tried Helm? It provides a unified history and buffer selector, which looks similar to what you want. You could bind the helm-mini command to a convenient key like F5.
You can check out Projectile. It was basically created to provide something similar to C-p, but has a lot of extra project level features as well. Projectile also has a Helm plugin to display project files and buffers with Helm.

MSI database contains set of tables, and I can successfully enumerate File table, which has all deployable file' meta-deta. What I need to extract is the actual contents of those files. msiexec, lessmsi, 7-zip all can do it, but I couldn't find any source/API to do it.
What I've discovered it that all other (resource) files are in Binary table, and Data field can be used to get content of those files (like icons, custom DLL etc).
Further, I found and know that Media table contains information about the .CAB file (MSI has all content embedded with <MediaTemplate EmbedCab="yes"/>. This simply means the CAB file contains the actual content. I probably need to read contents from "Structured Storage" of the .msi file.
How to extract the contents of CAB/MSI file, using native C Msi* functions?
Phil has given you the easy/simple answer but I thought I might give you a little more information since you've done some research. Checkout:
https://msdn.microsoft.com/en-us/library/windows/desktop/aa372919(v=vs.85).aspx
This is where the structured storage is. You'll see something like Disk1.cab as the Name (PK) and binary data. The data is a CAB file with the file entry in the cab matching the File.File column. From there you can use the File.FileName column to get the short name and long name (you'll want the long name no doubt) and do a joint to the Component table to get the directory table ID.
You'll also need to recurse the directory table to build the tree of directories and know where to put the files.
Fun stuff. There's some libraries in C# that make this WAY simpler. Or just call msiexec /a as Phil says. :)
The most straightforward to extract all the files to some location is to install the product in "advertised" mode. If you do a:
msiexec /a [path to msi] TARGETDIR=[some folder]
you'll see what happens.
In C++ call MsiInstallProduct () with that command line.
You have gotten many good answers already, including the use of dark.exe from the WiX toolkit. By downloading the WiX source code you should be able to get the code you need ready-made from there. I assume you may already have done this.
Chris has already linked to the DTF code you can check, but here is a link directly to dark.exe as well: https://github.com/wixtoolset/wix3/tree/develop/src/tools/dark. I would try both. This is C#, you seem to want native.
UPDATE: Before I get to the Win32 features you can use, check out this little summary of the C# DTF features: How to programmatically read the properties inside an MSI file?
Native Win32 functions: The database functions to deal with an MSI file can be found on MSDN (this is to deal with the MSI file as a database). There are also MSI Installer Functions (used to deal with the MSI file as an actual installer).
You can certainly find good examples of native code for this with a good Google search. Have fun!
BTW: It would help with a description of the actual problem you are trying to solve as well as what you need technically. There could - as always - be less involved ways to achieve what you need. Unless you are writing a security software or malware scanner or something super-involved.
And so it is clear: WiX's dark.exe fully decompiles MSI files into WiX source files and the resource files used to build them - you can then text and binary compare the various types of content (text compare for tables, binary compare for binaries, etc...). The process to do so via command line is described in the following answer: How can I compare the content of two (or more) MSI files? (this is about comparing MSI files, but one option to do so is to decompile them - see section on dark.exe - just for reference for others who find your question).
I like to link things together so we can find content easily at a later point in time. Strictly speaking it doesn't seem necessary here, you have what you need I think but others could perhaps benefit from some further links. Here are some related links:

For vim there is a filesystem explorer called NERDtree: https://github.com/scrooloose/nerdtree
Surely an alternative or superior package exists for Emacs?
I prefer dirtree (screenshot below) by Ye Wenbin. It feels pretty close to NERDTree / the TextMate drawer.
It took me a few minutes of trial and error to figure out the dependencies, so take a look at the install instructions (and a few minor edits to the source) I've got in this repo.
You can try NeoTree .

Have you looked at Speedbar ?
The Sunrise Commander seems to be a well written package, and it has a tree extension. For a screenshot of the tree extension in action, follow this link.
Who needs any tree, when you have the mighty ido-mode . If you can train your mind to find the files, rather than just your eyes whilst visually finding it, you will win. NO need to tell me how biology works, i don't care :-) you get the point.
Personally, I prefer the ECB's tree mode.

You should also check out the CEDET stuff.

They contain a lot of other useful stuff that you can use for similar development needs.
I use a little of emacs-nav and a little of dired to navigate my projects' file trees. For file management tasks, I mostly use bash (often from within emacs).
(Shameless reanswer from A good project tree browser for Emacs? - Stack Overflow)
I just now did a word search for "explore" in package-list-packages, and discovered project-explorer. Seems to fit exactly what I want today (I don't code hardly, but getting a grip on the structure of my Jekyll site).
Keys include TAB for folding and unfolding directories. Open files with RET or f, but with prefix, it will prompt nicely for which window, and even from there allow you to decide to use window or open up a new one to any side (I didn't find the prompt string in the package code, so it seems to leverage built in Emacs functionality nicely; indeed it looks like dired even).
It's available on Melpa and Marmalade, and packaged description points to sabof_project-explorer ยท GitHub.
I include the site's image for convenience:
I don't use projectile or helm, but it has some integration.
Try out lusty-explorer. It's a well done plugin.

Which configuration management tool is the best for FPGA designs, specifically Xilinx FPGA's programmed with VHDL and C for the embedded (microblaze) software?
There isn't a "best", but configuration control solutions that work for software will be OK for FPGAs - the flow is very similar. I use Subversion at work and git at home, and wrote a little on 'why' at my blog.
In other answers, binary files keep getting mentioned - the only binary files I deal with are compilation products (equivalent to software object and executables), so I don't keep them in the version control repository, I keep a zipfile for each release/tag that I create with all the important (and irritatingly slow to reproduce) ones in.
I don't think it much matters what revision control tool you use -- anything that you would consider good in general will probably be OK here. I personally use Git for a sizable Verilog + software project, and I'm quite happy with it.
What will bite you in the ass -- no matter what version control you use -- is this: The Xilinx tools don't generally respect a clean division between "input" and "output" or between (human edited) "source" and (opaque) "binary." Many of the tools like to store some state information, like a last-run time or a hash value, in their "input" files meaning that you'll get lots of false changes. Coregen does this to its .xco files, and project navigator (the main GUI) does this to its .xise files. Also, both tools have a habit of inserting or removing lines for default-valued parameters, seemingly at random.
The biggest issue I've encountered is the work-flow with Coregen: In many cases, at least one of the following is true:
You have to manually edit the HDL files produced by Coregen.
The parameters that went into Coregen are stored somewhere other than the .xco file (usually in what looks like an output file).
You have to copy-and-paste the output from Coregen into your top-level design.
This means that there is no single logical source/master location for your input to the core-generating process. So even if you have the .xco file under version control, there's no expectation that the design you're running corresponds to it. If you re-generate "the same" core from its nominal inputs, you probably won't get the right outputs. And don't even think about merging.
I suggest CM tools that support version labeling and binary files. Most Software CM applications are fine with ASCII text files. They may just store a "difference" file rather than the entire file for updates.
My recommendations: PVCS, ClearCase and Subversion. DO NOT USE Microsoft SourceSafe. I don't like it because it only supports one label per revision.
I've seen Perforce and Subversion used in a couple of FPGA-intensive companies.
We use Perforce, and its great. You can have your code that lives in Linux-land checked in side-by-side with your Specs and Docs that live in Windows-land. And you get branching, labels, etc.
I've seen everything from Clearcase to RCS used, and it is really all okay for this kind of thing. The important thing is to get a good set of check-in policies established for your group, and make sure they stick to it.
And have automated nightly regressions. That way, when someone breaks the rules, they can be identified and publicly shamed.
I have personally used Perforce, Subverion, git and ClearCase for FPGA projects. Since VHDL and C are just text files, any works fine. However be sure to capture the other project and contraint files and any libraries you use.
Also think about what to do with the outputs, e.g. log file and bitstreams. Both tend to be big and the bitstreams are binaries.
Previously I used Subversion but have switched to git two years ago. Git handles FPGA design files just as well as it handles every other text and binary file. Git is all you need for version controlling your files and artifacts.
For building the designs, I recommend just using a single ISE project called "ise" (living in a subdirectory called "ise/"). You can take a look at my (very modest) FPGA open-source project on github for the file layout. I don't bother storing the ISE files at all since they are easy to regenerate. The only things I save are the Verilog files and some ISIM waveform config files. In other projects that use coregen I save the coregen.cgp project file and all of the *.xco scripts for regenerating cores. Then I use a Makefile for actually running coregen on the *.xco files. There are a few other Xilinx-specific files you should version control too: *.ucf, *.coe, *.xcf, etc.
I experimented with using Makefiles and the Xilinx command-line tools but found that ISE did a much better job tracking dependencies and calling the tools with the right arguments. Just don't make the mistake of trying to version control your ise/ project files or you will go mad. Xilinx has something like 300 different file types which change every release. If you want to save a file, you can try the ISE project file itself with a .xise extension. Anything that is hard to recreate, like the golden bitfile that you know works and took 6 hours to build, you might want to copy that and configuration manage it explicitly.
Whenever I start a new project, I have to go through setting up the debugger with Eclipse time and time again before I can use it. Isn't there a default setting for all new C projects I can change?
I'm not sure exactly what you mean by "setting up the debugger" (perhaps you can clarify), but under "Preferences -> Run/Debug -> Launching -> Default Launchers" you should be able to select your preferred launcher for different kind of launch modes. This can also be selected individually for each launch configuration.
Typically it is up to the toolchain and/or project to determine which debugger/launcher is suitable to use for that specific project, but I know there is a bug in CDT which prevents toolchains from properly specifying the default launcher to use.
I only use Eclipse for Java, so I can't give you an authoritative answer. But since no one else seems to be answering:
Java projects have a (more or less) hidden file in the project directory called .project and another one called .settings . I'm not sure if this would apply to the C environment as well, but it seems likely. You may want to look at the set of such "hidden" files for a well set up project and a virginal project side by side to find out which settings make the difference.
Given that information, you may be able to simply edit (perhaps with some assistance from a script you can write yourself) the file(s) in question to do the configuration textually without a lot of mouse clicking.
How can I hide the files while installing my application using an Inno Setup made package? It can be hidden by
"[files]
attribs : hidden"
but it again can be seen by activating the windows option
"Show hidden file"
How can I hide it permanently to avoid user tampering with EXE file?
Can't be done. If you nee a detailed explanation why, see this blog post:
http://blogs.msdn.com/oldnewthing/archive/2005/04/19/409620.aspx
If you are really ambitious and you really have an issue with people "tampering" with your exe files you can perhaps encrypt your exe files, play with the PE (portable executable) and loader, or other stuff.
I doubt any of that is worth it. EXEs have been distributed by many software companies over the years. Your application is probably not that special to warrant anything out of the ordinary.
Set those flags, and concentrate on more important issues.
