Differences between .dll , .lib, .h files? .h - header file
a source file containing declarations (as opposed to .cpp .cxx etc. containing implementations)
.lib - static library may contain code or just links to a dynamic library compiled code that you link with your program The static library is included in your .exe at link
time. .dll - dynamic library
Just like a static one but you need to deploy it with your .exe file because its loaded at run time

Configuration tips No need of care about your systems is 64
bits or 32 bits 32 bits applications can run on 64 bits
machines without problems
Use 32 bits OpenCV library

Solutions and Projects Visual Studio provides two containers to help you
efficiently manage the items that are required by your development effort, such as references, data connections, folders, and files. These containers are called solutions and projects.
Visual Studio provides Solution Folders to organize related projects into groups and then perform actions on those groups of projects. Solution Explorer, an interface for viewing and managing
these containers and their associated items, is part of the integrated development environment (IDE).
By Dr. Xinwen Fu 11
CS@UML
Items Items can be files and other parts of your project
such as references, data connections, or folders In Solution Explorer, items can be organized
as project items, which are items that compose your project, such as forms, source files, and classes within a project in Solution Explorer.
as solution items for files that are applicable to your solution as a whole in the Solution Items folder of Solution Explorer.
as miscellaneous files that are not associated with either a project or a solution and that can be displayed in a Miscellaneous Files folder
By Dr. Xinwen Fu 12
CS@UML
Solutions as Containers Visual Studio implements conceptual containers called
solutions and projects to enable the integrated development environment (IDE) to apply its wide range of tools, designers, templates, and settings
Visual Studio automatically generates a solution when you create a new project
By Dr. Xinwen Fu 13
CS@UML
Advantages Solutions allow you to concentrate on developing
and deploying your projects, instead of sorting through all the details of managing project files, components, and objects.
Each Visual Studio solution allows you to: Work on multiple projects within same instance of IDE. Work on items using settings and options that apply to
an entire set of projects. Use Solution Explorer to help develop and deploy your
application. Manage additional files opened outside the context of a
solution or project.

Definition Files Visual Studio stores the definition for a solution in
two files: .sln and .suo In previous versions of Visual Studio, you might have
noticed the group (.vbg) or workspace (.dsw) files in Visual Basic and Visual C++, respectively.
The solution definition file (.sln) stores the metadata that defines your solution: Projects that are associated with the solution. Items available at the solution level that are not
associated with a particular project. Solution build configurations that set which project
configurations to apply in each type of build.
By Dr. Xinwen Fu 15
CS@UML
Definition Files (Cont’d) The metadata stored in the .suo file as you
construct a solution and set its properties is used to customize the IDE whenever the solution is active.
By Dr. Xinwen Fu 16
CS@UML
Projects as Containers To help you to organize and perform common tasks on the
items that you are developing, Visual Studio projects are used as containers within a solution to logically manage, build, and debug the items that comprise your application.
The output of a project is usually an executable program (.exe), a dynamic-link library (.dll) file or a module, among others.

Create a Visual Studio Solution1. In Visual Studio, click File, point to New, and
then click Project.2. In the New Project dialog box, in the
Project types pane, click Other Project Types, and then click Visual Studio Solutions.
3. In the Templates pane, click Blank Solution.
4. Enter the name of your project in the Name field, and then click OK.

Change the color of ink of Powerpoint Change the color of ink before starting a slide show
On the Slide Show menu, click Set Up Show. In the Pen color box, click the color you want, and then click OK.
Change the ink color during a slide show On the Slide Show toolbar, click or tap the pointer arrow, point to Ink
Color, and then click the color you want. Note Changing the color of the ink during the slide show affects the ink
for the ballpoint and felt tip pens only. Change the color of ink on a Tablet PC
Select the ink you want to format. On the Ink Drawing and Writing or Ink Annotations toolbar, tap Select
Objects. Tap the ink. Sizing handles and an outline of the ink shapes indicate that the ink is
selected. On the Ink Drawing and Writing or Ink Annotations toolbar, tap the
arrow next to Line Color. Tap the color you want to use.
Tip After you select a color, the Line Color button displays that color. You can
apply the same color again to any ink selection by clicking or tapping Line Color again.

cv Namespace All OpenCV classes and functions are in the cv namespace. Therefore, to access this functionality from your code, use
the cv:: specifier or using namespace cv; directive:1. #include "opencv2/core/core.hpp"2. ...3. cv::Mat H = cv::findHomography(points1, points2, CV_RANSAC,
5);4. ...
