【问题描述】:
我已将拼写检查合并到我的 win forms C# 项目中。这是我的代码。
public void CheckSpelling()
{
try
{
// declare local variables to track error count
// and information
int SpellingErrors = 0;
string ErrorCountMessage = string.Empty;
// create an instance of a word application
Microsoft.Office.Interop.Word.Application WordApp =
new Microsoft.Office.Interop.Word.Application();
// hide the MS Word document during the spellcheck
//WordApp.WindowState = WdWindowState.wdWindowStateMinimize;
// check for zero length content in text area
if (this.Text.Length > 0)
{
WordApp.Visible = false;
// create an instance of a word document
_Document WordDoc = WordApp.Documents.Add(ref emptyItem,
ref emptyItem,
ref emptyItem,
ref oFalse);
// load the content written into the word doc
WordDoc.Words.First.InsertBefore(this.Text);
// collect errors form new temporary document set to contain
// the content of this control
Microsoft.Office.Interop.Word.ProofreadingErrors docErrors = WordDoc.SpellingErrors;
SpellingErrors = docErrors.Count;
// execute spell check; assumes no custom dictionaries
WordDoc.CheckSpelling(ref oNothing, ref oIgnoreUpperCase, ref oAlwaysSuggest,
ref oNothing, ref oNothing, ref oNothing, ref oNothing, ref oNothing,
ref oNothing, ref oNothing, ref oNothing, ref oNothing);
// format a string to contain a report of the errors detected
ErrorCountMessage = "Spell check complete; errors detected: " + SpellingErrors;
// return corrected text to control's text area
object first = 0;
object last = WordDoc.Characters.Count - 1;
this.Text = WordDoc.Range(ref first, ref last).Text;
}
else
{
// if nothing was typed into the control, abort and inform user
ErrorCountMessage = "Unable to spell check an empty text box.";
}
WordApp.Quit(ref oFalse, ref emptyItem, ref emptyItem);
System.Runtime.InteropServices.Marshal.ReleaseComObject(WordApp);
// return report on errors corrected
// - could either display from the control or change this to
// - return a string which the caller could use as desired.
// MessageBox.Show(ErrorCountMessage, "Finished Spelling Check");
}
catch (Exception e)
{
MessageBox.Show(e.ToString());
}
}
拼写检查器运行良好,唯一的问题是当我尝试移动拼写检查器时,主窗体由于某种原因变得模糊。此外,当我关闭拼写检查器时,主窗体恢复正常。似乎它正在打开 Microsoft Word 然后隐藏窗口,只允许看到拼写检查器。请帮忙。
