本人用下列API函数实现向逻辑字体的转化,其可以设置字高字宽等等一系列功能,现本人更想通过该函数控制字间距的大小,也必须是逻辑字体情况下,请高手加以指点,谢谢!Public Declare Function CreateFontIndirect Lib "gdi32" Alias "CreateFontIndirectA" (lpLogFont As LOGFONT) As LongPublic Type LOGFONT
lfHeight As Long
lfWidth As Long
lfEscapement As Long
lfOrientation As Long
lfWeight As Long
lfItalic As Byte
lfUnderline As Byte
lfStrikeOut As Byte
lfCharSet As Byte
lfOutPrecision As Byte

Private Declare Function CreateFontIndirect Lib "gdi32" Alias "CreateFontIndirectA" (lpLogFont As LOGFONT) As Long【别名】
CreateFontIndirectA【说明】
用指定的属性创建一种逻辑字体 【返回值】
Long,执行成功则返回逻辑字体句柄,零表示失败 【备注】
VB的字体属性在选择字体的时候显得更有效【参数表】
lpLogFont ------ LOGFONT,这个结构定义了逻辑字体请求的属性
