excel - Pagesetup.printquality 导致类型不匹配错误

Question

我录制了一个用于页面设置的宏，它生成了一整套要设置的属性。然后我运行了这个宏，处理了一些信件，去了洗手间，喝了一杯咖啡，然后坐下来等待页面设置宏完成。不用说，处理速度非常慢。

我做了一些谷歌搜索，发现它的运行速度非常慢，并发现了三个建议。

1. 使用内置 VBA 4 宏来执行大部分页面设置属性，因为它运行速度更快。
2. 限制您要更改的属性
3. 仅更改需要更改的属性

3 与 2 有点相似，这是我决定采取的路线。基本上我会通过 if 语句运行每个属性更改。

IF .property <> wanted.value then .property = wanted.value

因此，通过一些文本操作，我快速转换了录制的宏，其中它将所有属性值设置为 IF THEN 检查，然后再设置相应的值。

当我运行代码时，出现错误“类型不匹配”。它没有带我到任何特定的线路。然而，当我单步执行代码时，它在以下行崩溃了:

If .PrintQuality <> 600 Then .PrintQuality = 600

没有 IF 的行工作正常，没有错误

.PrintQuality = 600

IF THEN 编码在这一行之后的几行中起作用。 抛出错误的 PRINTQUALITY 检查出了什么问题？

Answer 1

来自 PageSetup.PrintQuality 文档，

Horizontal print quality (1) or vertical print quality (2). Some printers may not support vertical print quality. If you don't specify this argument, the PrintQuality property returns (or can be set to) a two-element array that contains both horizontal and vertical print quality.

所以.PrintQuality <> 600返回 Type Mismatch由于600的比较到一个数组。

由于文档提到如果打印机不支持，尝试设置垂直打印质量可能会失败，我想这样的答案可能是答案(但未经测试，因为我的打印机支持两者):

On Error Resume Next
If .PrintQuality(1) <> 600 Then .PrintQuality(1) = 600
If .PrintQuality(2) <> 600 Then .PrintQuality(2) = 600
On Error GoTo 0
