Ft?=?New?Font("宋體",?9.0!,?CType((FontStyle.Bold?Or?FontStyle.Italic),?FontStyle))
也可以在設(shè)定粗體前先保存原有字體,可以方便還原;
Private?OldFont?As?Font?'舊的字體
OldFont?=?RichTextBox1.SelectionFont?'保存當(dāng)前字體?
RichTextBox1.SelectionFont?=?New?Font("宋體",?9.0!,?FontStyle.Bold)?'9號加粗宋體
換回原來的字體;
RichTextBox1.SelectionFont?=?OldFont?'設(shè)定回原來的字體
GDI繪圖用字體必須安裝才能使用
在客戶機部署應(yīng)用程序時,安裝該字體就行
能
我們寫exe程序時,默認字體是宋體,比較難看,指定了其他字體,但是其他用戶上沒有你指定的這個字體的話,也會變成默認的宋體。解決的辦法有這么幾個:
1,叫用戶安裝相應(yīng)字體,這個基本不可能實現(xiàn),因為沒有幾個人會進行這樣的操作;
2,給用戶安裝相應(yīng)字體,這個辦法可行,在制作安裝包時將字體打包進去,然后用戶安裝程序的時候連字體也一并安裝上去,一勞永逸;
3,把字體導(dǎo)入到程序資源中,讓程序直接調(diào)用字體資源,缺點是導(dǎo)致程序體積巨大;
4,將字體文件放到程序目錄里,在程序里單獨調(diào)用。
個人覺得第4種辦法比較方便,所以決定采用這種方法,把代碼寫出來給需要的同學(xué)。
引用:
Imports System.Drawing.Text
public sub Setfont()
dim AppPath as string = Application.StartupPath
try
dim font1 as PrivateFontCollection = new PrivateFontCollection()
font1.AddFontFile(AppPath + "\font\msyh.ttf") '字體的路徑及名字
dim myFont as Font = new Font(font.Families[0].Name, 9,FontStyle.Regular,GraphicsUnit.Point, 134)
'設(shè)置窗體控件字體,哪些控件要更改都寫到下面
label1.Font = myFont
label2.Font = myFont
label3.Font = myFont
button1.Font = myFont
button2.Font = myFont
button3.Font = myFont
button4.Font = myFont
button5.Font = myFont
catch e as exception
MessageBox.Show("字體不存在或加載失敗\n程序?qū)⒁阅J字體顯示", "警告",
MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
end try
然后在public sub Form1()
InitializeComponent()
Setfont() '啟動字體設(shè)置函數(shù)
end sub
可以使用GetItemText
方法:返回指定項的文本表示形式。使用形式如下:
GetItemText(item)
Private?Sub?Form_Load()
r=Dir(C:\WINDOWS\Fonts\微軟雅黑.ttf)?‘在C盤WINDOWS文件夾fonts中查找微軟雅黑
If?r""then
...(...填入)確認文件存在
Else
...(...填入)確認文件不存在
End?if
End?Sub
'新建一個VB.NET 項目,把原來所有代碼刪了,把下面的代碼復(fù)制貼上去解OK了

Public Sub New()
MyBase.New()
'該調(diào)用是 Windows 窗體設(shè)計器所必需的。
InitializeComponent()
'在 InitializeComponent() 調(diào)用之后添加任何初始化
End Sub
'窗體重寫 dispose 以清理組件列表。
Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
If disposing Then
If Not (components Is Nothing) Then
