我有以下函数,它应该返回我正在搜索的文本第一次出现的位置。问题:
- 返回 -1
- 当我将整个文档内容用作范围(或使用具有文档内容边界的范围)时,抛出 AV-s
我做了什么:
- 大量谷歌搜索,以找到问题的根源,或此代码的替代方案
- MSDN 挖掘
- 试错
这是代码:
function FindTextWord(wordApp: TWordApplication; afindText: OleVariant; startIndex, endIndex: Integer; findEndOffsetFast: Boolean): Integer;
var
matchCase : OleVariant;
matchWholeWord : OleVariant;
matchWildcards : OleVariant;
matchSoundsLike : OleVariant;
matchAllWordForms: OleVariant;
fWd : OleVariant;
wrap : OleVariant;
format : OleVariant;
replaceWith : OleVariant;
replace : OleVariant;
myRange : Range;
startSearchOffset: OleVariant;
endSearchOffset : OleVariant;
begin
WordApp.Selection.Start := 0;
WordApp.Selection.End_ := 0;
result:=-1;
try
if (Assigned(WordApp)) then
begin
if (startIndex<1) then
begin
WordApp.ActiveDocument.GrammarChecked:=true;
WordApp.ActiveDocument.SpellingChecked:=true;
WordApp.ActiveDocument.ShowGrammaticalErrors:=false;
WordApp.ActiveDocument.ShowSpellingErrors:=false;
startSearchOffset:=WordApp.ActiveDocument.Content.Start;
end else
begin
startSearchOffset:=startIndex;
end;
if (endIndex<1) then
begin
if (findEndOffsetFast)or(startIndex<1) then
begin
endSearchOffset:=WordApp.ActiveDocument.Content.End_;
end else
begin
endSearchOffset:=startSearchOffset+1;
WordApp.Selection.Start:=startSearchOffset;
while (WordApp.Selection.Start=startSearchOffset)and(endSearchOffset<WordApp.ActiveDocument.Content.End_)and(endSearchOffset-startSearchOffset<4000) do
begin
endSearchOffset:=endSearchOffset+1;
WordApp.Selection.End_:=endSearchOffset;
end;
endSearchOffset:=endSearchOffset-1-Length(afindText);
end;
end else
begin
endSearchOffset:=endIndex;
end;
myRange:=WordApp.ActiveDocument.Range(startSearchOffset,endSearchOffset);
myRange.Find.ClearFormatting;
myRange.Start:=Integer(startSearchOffset);
myRange.End_:=Integer(endSearchOffset);
MatchCase := False;
MatchWholeWord := TRUE;
MatchWildcards := False;
MatchSoundsLike := False;
MatchAllWordForms := False;
fWd := True;
Wrap := wdFindStop;
Format := False;
ReplaceWith := '';
Replace := wdReplaceNone;
if MyRange.Find.Execute(aFindText,MatchCase,MatchWholeWord,
MatchWildcards,MatchSoundsLike,
MatchAllWordForms,fWd,
Wrap,Format,ReplaceWith,Replace)
then begin
if (myRange.Start>=startSearchOffset) then
begin
if (myRange.Find.Found) then
begin
result:=myRange.Start;
end;
end else
begin
result:=FindTextWord(wordApp,afindText,startIndex,endIndex,false);
end;
end;
end;
except
end;
end;
更新
问题不在于替换文本(我必须删除可能出现在 word 文档中的所有 HTML 标签,但有以下变化:如果我遇到格式化标签,例如 b、i、u、s、strong 等,我必须删除它们并相应地格式化文本)
