首先建立一个工程文件，然后选菜单中的Project|AddClassModule加入一个新的类文件，并将这个类的Name属性改变为APIFont，然后在类的代码窗口中加入以下的代码：
OptionExplicit

PrivateDeclareFunctionCreateRectRgnLib“gdi32”(ByValX1AsLong,ByValY1AsLong,ByValX2AsLong,ByValY2AsLong)AsLong

在工程文件的Form1中加入一个PictureBox和一个CommandButton控件，然后在Form1的代码窗口中加入以下的代码：
OptionExplicit
DimAFAsAPIFont
DimX,YAsInteger
PrivateSubCommand1_Click()
DimIAsInteger
SetAF=Nothing
SetAF=NewAPIFont
Picture2.Cls
ForI=0To3600Step360
AF.Escapement=I
AF.SelectFontPicture2
X=Picture2.ScaleWidth/2
Y=Picture2.ScaleHeight/2
在字符串后面要加入7个空格
AF.FontOut“电脑商情报第42期”,Picture2,X,Y
AF.SelectOrgPicture2
NextI
EndSub
PrivateSubForm_Load()
Picture2.ScaleMode=3
EndSub
运行程序，点击Form上的Command1按钮，在窗口的图片框就会出现旋转的文本显示，程序的效果如图所示：
值得注意的问题是，由于Windows的动态连接库的中英文版本的关系，在一些系统中显示中文可能会有一些问题，大家可能看到，上面程序中的语句：AF.FontOut“脑商情报第42期”，Picture2,X,Y中的字符串后面有7个空格，这是对于“电脑商情报第42期”中的7个中文字符，中文系统计算的是7个字符，但是实际它们占据的是14个字节的空间，所以在输出时要在后面添加7个空格做“替身”。上面的程序在中文Win98，VB6下运行通过。->
