 Delphi+Word解决方案参考

    使用前,先根据需要建立一个空的WORD文件作为模板,在模板文件中设置好各种格式和文本。另外,其中的PrnWordTable的参数是TDBGridEh类型的控件,取自Ehlib2.6
    其中用到的shFileCopy函数(用于复制文件)和guiInfo函数(用于显示消息框)也是自己编写的,代码也附后。
示范代码如下:
    代码完成的功能:
1. 替换打印模板中的“#TITLE#”文本为“示范代码1”
2. 并且将DBGridEh1控件当前显示的内容插入到文档的末尾
3. 在文档末尾插入一个空行
4. 在文档末尾插入新的一行文本
5. 将文档中的空行去掉
if PrnWordBegin('C:/打印模板.DOC','C:/目标文件1.DOC') then
begin
PrnWordReplace('#TITLE#','示范代码1');
PrnWordTable(DBGridEh1);
PrnWordInsert('');
PrnWordInsert('这是新的一行文本');
PrnWordReplace('^p^p','^p',true);
PrnWordSave;
end;
源代码如下:
//Word打印(声明部分)
wDoc,wApp:Variant;
function PrnWordBegin(tempDoc,docName:String):boolean;
function PrnWordReplace(docText,newText:String;bSimpleReplace:boolean=false):boolean;
function PrnWordInsert(lineText:String;bNewLine:boolean=true):boolean;overload;
function PrnWordInsert(var imgInsert:TImage;sBookMark:String=''):boolean;overload;
function PrnWordInsert(var chartInsert:TChart;sBookMark:String=''):boolean;overload;
function PrnWordTable(var dbG:TDBGridEh;sBookMark:String=''):boolean;
procedure PrnWordSave;
procedure PrnWordEnd;
//Word打印(实现部分)
{
功能:基于模板文件tempDoc新建目标文件docName并打开文件
}
function PrnWordBegin(tempDoc,docName:String):boolean;
begin
result:=false;
//复制模版
if tempDoc<>'' then
if not shFileCopy(tempDoc,docName) then exit;
//连接Word
try
wApp:=CreateOleObject('Word.Application');
except
guiInfo('请先安装 Microsoft Word 。');
exit;
end;
try
//打开
if tempDoc='' then
begin
//创建新文档
wDoc:=wApp.document.Add;
wDoc.SaveAs(docName);
end else begin
//打开模版
wDoc:=wApp.document..Open(docName);
end;
except
guiInfo('打开模版失败,请检查模版是否正确。');
wApp.Quit;
exit;
end;
wApp.Visible:=true;
result:=true;
end;
{
