用VB创建/读取INI文件，并利用INI文件汉化程序，设置程序显示语言方法(一)

公司有些日文程序需要汉化，但如果直接手动在程序中汉化，下次程序修改了，还得再次汉化，这样肯定是不行的。

想到用INI文件来设置程序显示语言，但在网上找来找去，也找不到相关的例子，只好自己做了。

经过多次测试，终于实现了，在这里总结一下，应该有人会用到。

(没有细研究，只能实现对Label，CommandButton，Frame控件的汉化处理)

1，首先要根据窗体创建INI文件。

Public Sub prCreateIni() '根据窗体控件生成ini文件，可在文件中设置窗体显示字体

Dim pFileName, pstr As String
Dim pFileNum, pI

pFileName = App.Path & "ini" & App.EXEName & "_lang_" & Me.Name & ".ini"
pFileNum = FreeFile

Open pFileName For Output As #pFileNum

pstr = " "
Print #pFileNum, pstr

'设置节名
pstr = "[" & Me.Name & "]"
Print #pFileNum, pstr

'设置窗体标题
pstr = " Form." & Me.Name & " = Me.Caption
Print #pFileNum, pstr

Dim pCtr As Control
For Each pCtr In Me.Controls

If (TypeOf pCtr Is Label) Or (TypeOf pCtr Is CommandButton) Or (TypeOf pCtr Is Frame) Or (TypeOf pCtr Is CheckBox) Then
pstr = " " & pCtr.Name & " = " & pCtr.Caption
Print #pFileNum, pstr
End If

Next pCtr

Close #pFileNum

MsgBox "Ini file for [" & Me.Name & "] have created success!"

End Sub

然后，在窗体上添加一按钮，执行以下代码，对每个窗体生成ini文件

Private Sub Command1_Click()
form1.prCreateIni
form2.prCreateIni
form13.prCreateIni
End Sub

将各窗体生成的ini文件合并，命名为App.EXEName_Lang.ini。保存目录：App.Pathini

生成的ini文件内容示例如下：

[COMMON]
'此部分为公用过程，请直接添加
LANGUAGE = CHINESE
'LANGUAGE = JAPANESE

'系统语言
WINDOWS=CHINESE
'WINDOWS=JAPANESE

'控件caption字符集
Proportional Font = Simsun
'Proportional Font = MS PGothic

'控件文体内容字符集
Regular Font = Simsun
'Regular Font = MS Gothic

[FORM1]
cmdBatch = 批处理
cmdCancel = 取消
cmdSave = 保存
lblMax = Max
lblMin = Min

[FORM2]
cmdBatch = Batch
cmdCancel = Cancel
cmdSave = Save
lblMax = Max
lblMin = Min

2，使用INI文件设置窗体显示：在每个窗体中添加以下过程，并在form_load中调用此过程。

Private Sub prSetDisplay() '从INI文件中读取数据，设置窗体显示内容，需要在form_load中调用此过程
'Read ini file to Set form display. ( Need add in FormLoad)
'从INI文件中读取数据，设置窗体显示内容。(需要在FormLoad中调用此过程)

Dim pIniFile$

pIniFile = App.Path & "ini" & App.EXEName & "_Lang.ini"

If Dir(pIniFile) = "" Then
MsgBox "Ini file of [" & pIniFile & "] not found!"
Exit Sub
End If

Dim pLang$, pPrp_Font, pReg_Font, pWin$
Dim pCharset_data

pLang$ = cfReadIniFile(pIniFile, "COMMON", "LANGUAGE") ' "JAPANESE" or "CHINESE"
pPrp_Font = cfReadIniFile(pIniFile, "COMMON", "Proportional Font")
pReg_Font = cfReadIniFile(pIniFile, "COMMON", "Regular Font")

pWin$ = cfReadIniFile(pIniFile, "COMMON", "WINDOWS") ' "JAPANESE" or "CHINISE"

If (pLang$ = "JAPANESE") And (pWin$ = "JAPANESE") Then
pCharset_data = 1
ElseIf (pLang$ = "JAPANESE") And (pWin$ = "CHINESE") Then
pCharset_data = 1 '128
ElseIf (pLang$ = "CHINESE") And (pWin$ = "CHINESE") Then
pCharset_data = 1
ElseIf (pLang$ = "CHINESE") And (pWin$ = "JAPANESE") Then
pCharset_data = 128
End If


'使用示例
'Label1(0).FontName = pPrp_Font
'Label1(0).Font.Charset = pCharset_data
'Label1(0).Caption = capt_data(1, 1)
'txtPrt.FontName = reg_font

Dim pCtr As Control
Dim pSection As String

pSection = Me.Name
'设置窗体标题
Me.Caption = cfReadIniFile(pIniFile, pSection, "Form." & Me.Name)
'设置各控件标题
For Each pCtr In Me.Controls
If (TypeOf pCtr Is Label) Or (TypeOf pCtr Is CommandButton) Or (TypeOf pCtr Is Frame) Or (TypeOf pCtr Is CheckBox) Then
  ’pCtr.FontName = pPrp_Font
’pCtr.Font.Charset = pCharset_data
pCtr.Caption = cfReadIniFile(pIniFile, pSection, pCtr.Name)
End If
'If (TypeOf pCtr Is SSTab) Then
'pCtr.FontName = pPrp_Font
'pCtr.Font.Charset = pCharset_data
'pCtr.Caption = cfReadIniFile(pIniFile, pSection, pCtr.Name)
'End If
Next pCtr

End Sub

3，需要以下过程支持,请将以下代码添加到公用模块中。

Public Function cfReadIniFile(iniFile$, header$, item$) As String '从INI中读取数据

Dim n As Integer
Dim dat$, a$
Dim flag As Boolean

If Dir(iniFile$) = "" Then
n = MsgBox("File:" + iniFile$ + " not found !!", vbCritical + vbOKOnly)
End
Else
n = FreeFile
flag = False
dat$ = ""
Open iniFile$ For Input As n
Do While Not EOF(n)
Line Input #n, a$
a$ = Trim(CutQuote(a$))
If a$ <> "" Then
If Not flag Then
If UCase(a$) = "[" + UCase(header$) + "]" Then flag = True
Else
If Left$(a$, 1) = "[" Then
Exit Do
Else
If UCase(GetItem(a$, 1)) = UCase(item$) Then
dat$ = GetItem(a$, 2)
Exit Do
End If
End If
End If
End If
Loop
Close #n
cfReadIniFile = dat$
End If

End Function

Public Function CutQuote(dat$) As String

If Left$(dat$, 1) = "'" Then
dat$ = ""
End If
CutQuote = dat$

End Function

Public Function GetItem(record$, orderNo) As String 'Get string from string which devides by commas

Dim a$, item$
Dim j, pnt
Dim dqflag As Boolean

item$ = "": pnt = 1: dqflag = False
For j = 1 To Len(record$)
a$ = Mid$(record$, j, 1)
If a$ = Chr$(34) Then ' chr$(34) is bouble quotaion
dqflag = Not dqflag
End If
If dqflag Then
item$ = item$ + a$
Else
If (a$ = ",") Or (a$ = "=") Then
If pnt = orderNo Then
Exit For
Else
item$ = "": pnt = pnt + 1
End If
Else
item$ = item$ + a$
End If
End If
Next
If pnt <> orderNo Then
item$ = ""
Else
item$ = LTrim(RTrim(item$))
If Left$(item$, 1) = Chr$(34) Then
If Right$(item$, 1) = Chr$(34) Then item$ = Mid$(item$, 2, Len(item$) - 2)
End If
End If
GetItem = item$

End Function

这样就可以了，这样你可以修改ini文件中的各控件的caption，来设置窗体显示的字体内容了。

只要程序控件没有变化，即使程序修改了，我们不用再修改汉化了! 还是很方便的。
