I have a c++ console project with all the models, and program logic.
I would like to create an interface that will enable user interaction.
Is there an easy way to import all my classes and code to be used in the Qt project? Or should I download the Qt plugin for VS?
EDIT:
I am targeting Qt 5.2, and VS 2012.
Maybe my question isn't to clear. I'd rather leave the console project alone, and just use the models and logic.

I believe, the plugin would make your life somewhat simpler. Please note that they do not work with the free express edition though, so if you can only use that, it is not your piece of cake.
You can download the Qt 4 add-in from here, and the Qt 5 add-in from here.
You can leave the console project as is, and you can link against the common functionality in your Qt frontend by selecting the desired library path and name of your library covering the models and the business logic.

Code has been developed and deployed from environments for many years without any source control. Now a source control solution is needed. I am thinking of using Git. I know the hooks have to be written and I am fine with that. But where do we start?
If you are using recent (2016.2+) versions of Caché, consider using Atelier as IDE. Atelier is based on Eclipse, so you can use any existing source control plugins for Eclipse.
If your IDE is Studio the good start is

Is there anyway that we an use visual studios source code into Qt source code? to develop a application on image processing.
i had a program on visual studio but i don't understand how to use that code in Qt 5.
can anyone please tell me how can we use it
Thank you in advance
actually, it depends how is your project.
if you previous project is C++ and design good. UI just a present layer, it should not be heavy work.
but if your image processing logic are strong related to MFC, you might spend lots of time on your migration.
I am interested to write a GUI based tool which would generate code in return. Something similar to VB GUI interface or Xcode's Interface Builder. I am going to use QT tookkit which is cross platform.
Can you help me to point out some resources which could be helpful to make such tools?
Thanks
Qt creator comes with an integrated UI Designer. The designer can be used stand alone or integrated into Visual Studio as well.
I want to play around a bit with FLASH for app development. I'm looking for a good IDE for that. Someone suggested Flash Develop.
Flash Builder
Pros
better debugging and profiling
visual designer for MXML
because of Eclipse: support for other languages (eg. with Aptana, PDT...) and usage of plug-ins for the Eclipse Platform with features not shipped with FlexBuilder (code snippets with CFEclipse "Dynamic Snippets", "auto-code" for getter/setters with Monkey scripts...)
support of virtual folders/files (links to external files/folders handled intern by Eclipse, so also working on Windows)
refactoring (renaming of classes, functions, properties with automatic changing of dependencies)
Cons
Commercial license
Big and because of Eclipse problematic with newer Eclipse versions for the FlexBuilder plug-in version (eg. not working with Eclipse Ganymede 3.4.1)
adding and configuring the missing features with Eclipse plug-ins needs time and searching in the Internet (which plug-in? settings etc.)
Code assist only average and sometimes buggy eg. if correct imports are missing ("java.lang.NullPointerException")
missing of a code formatter or automatic get/setters (but there are solutions with other Eclipse plugins like Monkey Scripts, CFeclipse, Flexformatter "FlexPrettyPrintCommand"...)
sometimes a bit sluggish if background tasks in Eclipse are working
no package explorer
AS2 and AS3 only - no Haxe
FlashDevelop
Pros
free and Open Source (developed with C#)
lightweight and snappy
best available Code Assist for ActionScript
supports all flash languages - AS2, AS3, haxe
"auto code" for automatic getter/setter, variables, code for event handlers
code snippets with integrated snippet editor
extendible with plug-ins
support for asdoc comments
package explorer (show classes, symbols from a SWC file)
basic refactoring
multiple source code folders per project
useful plugins : ANT integration, SWC creation, mini map, quick navigate
Cons
only for Windows
no visual designer for MXML
no support of virtual folders/files inside the project
weak refactoring
changing classpaths must be done manually
plug-ins often not working in newer versions and many plug-ins are only rarely updated
limited support for debugging Haxe applications
Common
Pros
projects for full range of flash apps : websites, AIR (desktop, mobile)
debugging of FP/AIR apps with breakpoints and stepping
debugging with watch windows and locals
support for ASDoc comments
automatic adding of imports and organizing of imports
class wizard
SVG/GIT integration
Cons
no editing of graphics or animation (use Flash IDE for that)
Summary
For debugging, visual design of MXML forms : Flash Builder
For coding AS2/AS3/Haxe projects under Windows : FlashDevelop
Major reason to use FlexBuilder: has a real debugger you can set breakpoints and single step and watch/edit variables.
Unless FlashDevelop has .. developed .. don't think it got any of that yet.
BTW - if you are a student/teacher FlexBuilder can be had for free
Flex builder has a design view for MXML so you can build more visually. Flashdevelop on the other hand is free!
I've been using Flash Developer. Trying now FlashDevelop. FlashDevelop is fast and light, and I'm trying to switch just because of that.
I'm using HG + TortoiseHG for source control. I have 2 screens, so having external source control is not a big problem. Also the IDE stays a little cleaner by not having all the little source control icons.
DesignView helps with not having integrated design.
Also, I can debug with FlashDevelop and see the variables. I'm using FD3.2.1.
Along with what was already mentioned, Flex Builder has some nice tools that helps a developer to learn how to create a data enabled Flex application in form of the Data Wizards and also a nice web services introspection tool that automatically creates an ActionScript 3 client for a web service.
I'm using the new Jetbrains IntelliJ 8, and it's great (especially if your used to java developement). Has a lot better XML/JavaScript editors that any other IDE.
The latest version of IntelliJ also has a good flex/javascript debugger.
Here are two objective contrasts between FlashDevelop (with the Flex 3 SDK) and FlexBuilder. First, only FlexBuilder includes AdvancedDataGrid. Second, FlashDevelop has no source control integration.
AdvancedDataGrid is not included in either the free or open source Flex 3 SDKs; if you want it, you have to buy FlexBuilder. (I assume it is probably possible to use it via another SDK if you possess FlexBuilder.)
FlashDevelop doesn't have any source control integration, FlexBuilder possesses the existing, stable source control options for Eclipse. This includes Subclipse for SVN, as well as a lot of other things. As a longtime Visual Studio and Emacs user, in FlashDevelop I'm beginning to feel unsatisfied with leaving the editor to check in.
Flash Builder, even in version 4.5, has primitive, useless syntax coloring and customization features. From a 700$ package I was expecting at least what I can do with my free text editor.
In the syntax coloring preferences, there is a total of 6 keywords, and you cannot add any custom one.
How am I expected to code having variable names, function calls, and classes look exactly the same?
I will stick to Flash Pro CS5.5 and SciTe.
I have created a desktop app and now I need to install in on a client's computer.
However, the client would like to have a wizard to install. Like Visual Studio setup project allows you to add an installer.
Does Qt allow you to create an installer or do I need to use a 3rd party installer like InstallShield or Wise?
You should use the Qt Installer Framework :
http://doc.qt.io/qtinstallerframework/ifw-overview.html
I use Inno and like it a lot. I've tried a few others and this one worked well for me. (and free)
You definitely need a third party installer. A few good ones have already been mentioned. If you decide to go with a paid solution bitrock's installer is a perfect choice and they are also Qt centric and their main business is around Qt.
As an open source alternative I would suggest NSIS
If you only target Windows, you can use WiX (Windows Installer XML), which can be integrated into Visual Studio and MSBuild, so relatively easy to use. It's free and produces valid MSI files, which may be a requirement anyway.
If you rather need a simple wizard setup, give InnoSetup a try.
I think better to use a third party software like installshield. They are optimized for the packaging purpose and provide much customizable options.
If you have Visual Studio already, you can continue to use a setup project to distribute your application. The tools are built in. This is the technology that WiX "replaced" (more on that later), and it's what I do. It's not an ideal solution, but it gets me an MSI, which is how Windows software should be installed these days. Using InstallShield or something might be better, but to be honest I've never had a good experience with any third party installers. This is why I just stuck with the less-than-ideal setup project; it beats spending a lot on expensive, ugly and often frustrating third party installer creation tools. In short, it's a very pragmatic solution, and pragmatic solutions make sense.
As for WiX: I really don't recommend it at all. It seems like a great idea, but after a few months I found myself switching back to the setup projects. Even though he's been using WiX for a year more than I have been using setup projects, our WiX expert takes twice as long to get anything done. (He's a terrific programmer, too, just a bit blinded by open source.) You end up with thousands of copied text lines that you need to maintain. With a couple different projects, it becomes an unmaintainable mess.
I would not suggest attempting to build an installer in Qt yourself. In addition to having to get a lot of behavior just right, as a Qt application it will require the Qt libraries. Unless you statically link them, which is possible with the commercial edition (not LGPL) but difficult and not recommended. Plus then you'd be including two copies of the Qt libraries in your download.
Qt itself seems to use the nullsoft installer. That alone should tell you building your own is not a good idea. :)
