我正在使用Visual Studio 2017 Community v14.0.25431.01 Update 3,并且未显示错误.正如您在VS 2015中看到的,我可以看到下划线但在VS2017中没有的错误.

我有一个用户定义的函数，我想在自定义数据验证中使用它。我的函数工作正常，但是当我在数据验证中使用它时，每次都出错......

有代码：

Public Function AlphaNumeric(pValue) As Boolean
    Dim LPos As Integer
    Dim LChar As String
    Dim LValid_Values As String

    'Start at first character in value
    LPos = 1

    'Test each character in value
    While LPos <= Len(pValue)
        'Single character in value
        LChar = Mid(pValue, LPos, 1)

        'If character is not alphanumeric, return FALSE
        If InStr(REFALPHACHAR, LChar) = 0 Then
           AlphaNumeric = False
           Exit Function
        End If

        'Increment counter
        LPos = LPos + 1
   Wend

   'Value is alphanumeric, return TRUE
   AlphaNumeric …

如何将记录集中的数据填充到列表对象中？下面的代码并不完全有效：

oCN.ConnectionString = "DRIVER={SQL Server};Server=SRVSQL;Database=TEST;"
oCN.Open
Dim sqlString As String
sqlString = "SELECT * FROM MYTABLE"
oRS.Open sqlString, oCN

With Feuil3.ListObjects("TableArticles")
    If Not .DataBodyRange Is Nothing Then
        .DataBodyRange.Delete
    End If

    ' This make a 91 error
    Call .DataBodyRange.CopyFromRecordset(oRS)
    ' This copy data into sheet, not into listobject
    Call Feuil3.Range("A2").CopyFromRecordset(oRS)
End With

当我尝试通过此命令安装less:

npm install less .

我收到一个错误:

您好，不知道如何将光标放在 DatagridCell 内并选择所有文本

下面的代码将焦点设置在单元格上，开始编辑。但光标不在单元格内，因此用户无法开始键入文本。此外，未选择，因此用户必须手动选择文本，而不是直接替换值。

Mainwindow.xaml.cs：

    private void GrdLignes_SelectionChanged(object sender, SelectionChangedEventArgs e)\n    {\n        foreach (var c in GrdLignes.SelectedCells)\n        {\n            if (c.Column.Header.ToString() == "Quantit\xc3\xa9 Livr\xc3\xa9e")\n            {\n                var cellContent = c.Column.GetCellContent(c.Item);\n                if (cellContent != null)\n                {\n                    var dc = (DataGridCell)cellContent.Parent;\n                    dc.Focus();\n                    dc.IsEditing = true;\n                }\n            }\n        }\n    }\n

编辑：我说光标=闪烁插入符
