The method and initialization of using GDI + in vc6.0

GDI + is a sub-system in Windows XP. It is mainly responsible for outputting information on the display screen and the printing device. It is a set of application programming interfaces implemented through C ++ class. As the name suggests, GDI + is the successor of the previous version of GDI. For compatibility considerations, Windows XP still supports the previous version of GDI, but when developing new applications, developers should use GDI + to meet the graphics output needs, because GDI + has optimized the GDI in previous Windows versions and added many new features.

Unfortunately, vc6.0 does not allow you to use GDI + directly. The following describes a convenient method for using GDI + in vc6.0. The procedure is as follows:

1.copy the files in the uplodes and Lib files to the uplodes and Lib folders in the VC directory;

GDI + for vc6.0 SDK:

2. Complete the initialization in the project where you are going to use GDI +:

Add the following code to the stdafx. h header file:

// Added header file
# Include <comdef. h> // initialize the comport.

# Ifndef ulong_ptr
# Define ulong_ptr unsigned long *
# Include "gdiplus. H"
Using namespace gdiplus;
# Endif
// End

3. Add the xxxdlg. h header file to the public file.

Ulong_ptr m_pgditoken;

 

4. Add in program Initialization

// Two variables used by GDI +
Gdiplusstartupinput m_gdiplusstartupinput;
// M_pgditoken;
// Load GDI +
Gdiplusstartup (& m_pgditoken, & m_gdiplusstartupinput, null );

5. Add it before exiting the program

// Uninstall GDI +
Gdiplusshutdown (m_pgditoken );

6. Add gdiplus. lib to project> stting> link> Object/libary.

In this way, you can use GDI + for your project. There is no technical content!
