问题描述

我将参数As@Name传递给vb.net代码中的水晶报告...但是当报告打开时它会提示我输入离散参数值...下面是传递参数的代码行。 />

推荐答案

crReportDocument.DataDefinition.FormulaFields.Item("Dataini").Text = "''" & DTpini.Value.Date & "''"
            crReportDocument.DataDefinition.FormulaFields.Item("Datafim").Text = "''" & Dtpfim.Value.Date & "''"
            crReportDocument.DataDefinition.FormulaFields.Item("Machine").Text = "''" & Trim(TXT_MACHINE.Text) & "''"

在设计参数时，参数的确切名称是什么？它真的有@在它面前吗？因为我认为你不需要它。



如果不是这样的话，你能不能包含更多的代码。在显示报告之前看看你是否正在做其他事情，以及如何显示报告等，这将是很好的。

What is the exact name of the Parameter when you are designing it? Does it really have the @ in front of it? Because I don''t think you need it.

If that''s not it, could you include a bit more code. It would be nice to see if you are doing anything else before displaying the report, and how you are displaying the report, etc.
