Question

frm1 中的代码， 这是在 orderId 的地方创建子 在 TbOrderMedicine col orderId 中

Sub New(ByVal orderId)

    ' This call is required by the designer.
    InitializeComponent()

    ' Add any initialization after the InitializeComponent() call.
    CrystalReportViewer1.SelectionFormula = " {TbOrderMedicine.orderId}='" & orderId & "' "
    CrystalReportViewer1.RefreshReport()

End Sub

btn 打印机 BillN 中的代码

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Dim Frm1 As New Form1(lbserviceid.Text)
        Frm1.Show()
    End Sub

Answer 1

尝试从选择公式中删除单引号。就像：

CrystalReportViewer1.SelectionFormula = " {TbOrderMedicine.orderId}=" & orderId
