如何检查一个 com子是否是空洞而不设点?
原标题:how to check if a combobox is empty without setfocus?

一、需要了解是否将任何案文输入“ com”箱

如果是:

If comboReason1.Value <> "" Then

it gives me an error, and 如果是:

If comboReason1.Value <> Null then

这并不奏效。

如何检查是否将案文输入“ com”箱?

最佳回答
If IsNull(comboReason1.Value) then
问题回答

我不能很快地检验这一状况,而是尝试。

if comboReason1.Text<>"" then
