如何在 Crystal Reports 中的 StringVar 中插入换行符 [英] How to insert a line break in a StringVar in Crystal Reports

问题描述

如何在 Crystal Reports 的 StringVar 中输入换行符(或其他通常用转义字符解决的非文本字符)?

How do I enter a line break (or other non-text characters usually solved with escape characters) in a StringVar in Crystal Reports?

想要的输出:

第 1 行
第 2 行

line 1
line 2

我尝试过 StringVar s := "line 1 line 2";，但这不起作用.

I've tried StringVar s := "line 1 line 2";, but that does not work.

推荐答案

可能改进不大，但您可以构建一个字符串格式的自定义函数:

It may not be much of an improvement, but you could build a string-formatting, custom function:

// sf()
Function (Stringvar text)

    Stringvar Array keys := ["
"];
    Stringvar Array values := [Chr(10)+Chr(13)];

    Numbervar i;

    For i := 1 to Ubound(keys) do (
        text := Replace(text, keys[i], values[i])
    );

    text;

//{@ text}
sf("line 1 
 line 2")

如果您需要支持其他转义序列，这将为您提供一些可扩展性.

This would offer you some extensibility should you need to support additional escape sequences.
