delphi中的记事本问题
大家好，我们使用的是Delphi5版本。在delphi中打开记事本时遇到问题。我们希望通过单击按钮打开记事本，并将数据传递给它，以便记事本可以显示该数据。我不想保存它。请帮我解决这个问题。谢谢。您可以在按钮单击事件中使用以下命令。指定要在delphi中的记事本问题,delphi,delphi-5,Delphi,Delphi 5,大家好，我们使用的是Delphi5版本。在delphi中打开记事本时遇到问题。我们希望通过单击按钮打开记事本，并将数据传递给它，以便记事本可以显示该数据。我不想保存它。请帮我解决这个问题。谢谢。您可以在按钮单击事件中使用以下命令。指定要在textFileName.txt中打开的文件名 ShellExecute（句柄，'open'，c:\windows\notepad.exe'，'textFileName.txt'，nil，SW_SHOWNORMAL） 如果您想打开一个空白的txt文件并且不想保存
textFileName.txt中打开的文件名
ShellExecute（句柄，'open'，c:\windows\notepad.exe'，'textFileName.txt'，nil，SW_SHOWNORMAL）
如果您想打开一个空白的txt文件并且不想保存任何数据，您可以在单击事件上使用以下方法。
shell执行（句柄，'open'，c:\windows\notepad.exe'，nil，nil，SW\u SHOWNORMAL）
在uses类中添加ShellApi
更新代码
procedure TForm1.Button1Click(Sender: TObject);
var
tempString : TStringList;
begin
tempString := TStringList.Create;
try
tempString.Add('The text you wanted to display');
tempString.SaveToFile('C:\~tempFile.txt');
finally
tempString.Free;
end;
ShellExecute(Handle,'open', 'c:\windows\notepad.exe','C:\~tempFile.txt', nil, SW_SHOWNORMAL) ;
end;
您可以使用以下内容：
uses
Clipbrd;
procedure LaunchNotepad(const Text: string);
var
SInfo: TStartupInfo;
PInfo: TProcessInformation;
Notepad: HWND;
NoteEdit: HWND;
ThreadInfo: TGUIThreadInfo;
begin
ZeroMemory(@SInfo, SizeOf(SInfo));
SInfo.cb := SizeOf(SInfo);
ZeroMemory(@PInfo, SizeOf(PInfo));
CreateProcess(nil, PChar('Notepad'), nil, nil, False,
NORMAL_PRIORITY_CLASS, nil, nil, sInfo, pInfo);
WaitForInputIdle(pInfo.hProcess, 5000);
Notepad := FindWindow('Notepad', nil);
// or be a little more strict about the instance found
// Notepad := FindWindow('Notepad', 'Untitled - Notepad');
if Bool(Notepad) then begin
NoteEdit := FindWindowEx(Notepad, 0, 'Edit', nil);
if Bool(NoteEdit) then begin
SendMessage(NoteEdit, WM_SETTEXT, 0, Longint(Text));
// To force user is to be asked if changes should be saved
// when closing the instance
SendMessage(NoteEdit, EM_SETMODIFY, WPARAM(True), 0);
end;
end
else
begin
ZeroMemory(@ThreadInfo, SizeOf(ThreadInfo));
ThreadInfo.cbSize := SizeOf(ThreadInfo);
if GetGUIThreadInfo(0, ThreadInfo) then begin
NoteEdit := ThreadInfo.hwndFocus;
if Bool(NoteEdit) then begin
Clipboard.AsText := Text;
SendMessage(NoteEdit, WM_PASTE, 0, 0);
end;
end;
end;
end;
procedure TForm1.Button1Click(Sender: TObject);
begin
LaunchNotepad('test string');
end;
如果你不想让他们保存数据，那么最好让你自己的记事本看起来很像，毕竟，这正是TMemo的优点，然后只允许他们编辑文本——如果这是你的要求的话。否则，几乎不会阻止他们保存文件。Delphi中的记事本

您正在尝试打开记事本应用程序还是简单的txt文件？我想打开记事本应用程序，以便根据用户的不同保存记事本数据。谢谢。也许你可以写一个带TMemo的小表单，然后放下记事本？@naren一个带alClient的TMemo，在一个TForm里，和记事本差不多，你可以得到更多的控制。实际上你不想保存文件。我想通过delphi将数据传递到记事本，并从记事本保存数据。谢谢。如果您想打开记事本应用程序，用户将在上面键入内容，但不一定要保存数据。我说的对吗？不，实际上我有一个字符串数据，我想显示在记事本上。在记事本中打开该文件后，用户将决定是否保存该文件。感谢+1提供了一个答案，将文本传递到记事本，而不将其保存到文件，正如OP要求的那样。+1表示WaitForInput。我编辑了您的答案，以满足用户（如我）安装了定制的记事本，如Notepad2、notepad++，等等。。。虽然由于unicode问题，我无法通过WM_SETTEXT使其工作，所以我使用了剪贴板。@NGLN-尝试为一系列文本编辑程序找到（活动）编辑窗口不会有意思，所以剪贴板可能是替代记事本的最佳选择。不过，可能还有其他问题，例如，我在记事本++中有“记住下一次发布的当前会话”，所以它在发布时从不打开空文档。。无论如何，感谢您的编辑，也感谢您没有为我的“开始”换行@Sertac是的，我真的很想知道您希望end-else-begin
语法如何@Sertac在再次阅读您的评论之后，GetGUITreadInfo查找活动窗口似乎不是问题，但我使用剪贴板的原因是发送WM_SETTEXT只会将第一个字符插入记事本*编辑控件，我将其转换为unicode问题。
