首先,請允許我向您提供我的代碼:值不能轉換爲「Microsoft.Vbe.Interop.Forms.ReturnBoolean」
Private Sub txtLatMin_Exit(ByVal Cancel As ReturnBoolean)
Dim i_SelStart As Long
Dim str_Prompt As String
'Save the cursor position.
i_SelStart = txtLatMin.SelectionStart
'Remove characters that we can't use.
txtLatMin.Text = NumericPortion(txtLatMin.Text, True)
'Enforce the maximums:
If Val(txtLatMin.Text) + Val(txtLatSec.Text)/60 >= 60 Then
str_Prompt = "The maximum number of latitude minutes is 59.999."
MsgBox(str_Prompt, vbExclamation, "Notification")
Cancel = True
ElseIf Val(Me.textbox_Latitude_Degrees.Text) + Val(txtLatMin.Text)/60 + Val(txtLatSec.Text)/3600 > 89.99 Then
str_Prompt = "The maximum number of latitude degrees is 89.99."
MsgBox(str_Prompt, vbExclamation, "Notification")
Cancel = True
End If
'Restore the cursor position.
txtLatMin.SelectionStart = i_SelStart
End Sub
它標記錯誤在這個崗位標題取消=真
請記住,我從VB6代碼轉換到VB.NET
會不會有什麼建議的人可以爲我提供?
考慮扔掉,並徹底重寫代碼。遷移助手僅適用於不會更改的代碼。只要您需要進一步開發它,從頭開始並正確執行它會更好,因爲您遷移的代碼總是會變得非常糟糕。你*不*要保持該代碼。 – 2012-03-10 19:55:52
