赖立谦·青竹软件</font></span></p><p> 大家知道用Deiphi开发应用程序时标签是必不可少的，但是Deiphi提供的Label构件只支持横排方式的标签，而不支持竖排方式标签。</p><p> 编写一段简单的函数就可以把标签从横排变成竖排。因为中文字符集是用两个字节表示一个字符的，所以应在字符串的每两个字节之间加入回车换行符。这个函数的参数是一字符串，返回值是在中文字符之间添加了回车换行符的一个新的字符串。</p><p> 下面就举例说明：我们以竖排方式显示一首诗。</p><p> 新建一工程。</p><p> 首先在implementation部分定义一个字符串数组常量poemary，该数组的每一个成员顺序存放了诗中的一句。</p><p> const</p><p> poemary: array[0..6] of string = ('游子吟', '慈母手中线','游子身上衣', '临行密密缝', '意恐迟迟归', '谁言寸草心','报得叁春晖');</p><p> 随后，在implementation部分加入字符串转换函数，代码如下：</p><p> function convertstring(source:string):string;</p><p> var</p><p> i,j:integer;</p><p> a,b:array[0..50] of char;</p><p> begin</p><p> StrPCopy(a, source) ;</p><p> j:=0; i:=0;</p><p> while (a[j] <>＃0) do begin</p><p> b[i]:=a[j];</p><p> if (j mod 2=1)and(j>0) then begin</p><p> Inc(i); b[i]:=＃13;</p><p> end;</p><p> Inc(j); Inc(i);</p><p> end;</p><p> b[i－1]:=＃0;</p><p> result:= strpas(b);</p><p> end;</p><p><br> 最后添加Form1的OnCreate事件。注意：要在uses子句中添加单元名称stdctrls。</p><p> procedure TForm1.FormCreate(Sender: TObject);</p><p> var</p><p> labary:array[0..6] of Tlabel;</p><p> i:integer;</p><p> begin</p><p> for ⌨️ 快捷键说明
