检查单元格是否为空

Question

I am trying to check if the cell (A5) in sheet tstDash is empty. 我试图检查表tstDash中的单元格（A5）是否为空。 Currently the cell contains a formula but sometimes it the result is blank and sometimes is a number. 目前，单元格包含公式，但有时结果为空白，有时为数字。

If it is blank, I want a message box. 如果它是空白的，我想要一个消息框。 Otherwise perform other function. 否则执行其他功能。

I have this code but it is completely ignoring the line and giving me fits. 我有这个代码，但它完全忽略了这条线，让我适合。

If chk25thPercentile.Checked = True And Globals.tsdDash.Range("A5").Value Is DBNull.Value

Answer 1

尝试这个 ..

If chk25thPercentile.Checked And IsDBNull(Globals.tsdDash.Range("A5").Value)

Answer 2

What language are you writing in ? 你在写什么语言？ VBA or VB.Net ? VBA还是VB.Net？ VBA won't accept IsDBNull. VBA不接受IsDBNull。 If you are in VBA you want to be testing for the blank result of the formula, which is probably just an empty string "" I expect you need something like 如果你在VBA中，你想要测试公式的空白结果，这可能只是一个空字符串“”我希望你需要像

If chk25thPercentile.Checked And Globals.tsdDash.Range("A5").Value = ""

That is assuming that the result of your formula is an empty string, if the cell is actually blank, ie, without a formula you might want to look at ISBLANK 假设您的公式的结果是空字符串，如果单元格实际上是空白的，即没有公式，您可能需要查看ISBLANK
