想读取第三方软件里面stringgrid里面的刷新数据，最后一条。跑不通
delphi代码。gpt给的。报错。
procedure TForm1.Button1Click(Sender: TObject);
var
hWebslin: HWND; // Webslin.exe main window handle
hStringGrid: HWND; // StringGrid handle
RowCount: Integer; // Number of rows
ColCount: Integer; // Number of columns
RowIndex: Integer; // Row index
ColIndex: Integer; // Column index
CellTextLength: Integer; // Cell text length
CellTextBuffer: PChar; // Cell text buffer
GM_GETROWCOUNT,GM_GETCOLCOUNT,GM_GETCELLTEXTLENGTH:integer;
GM_GETCELLTEXT: PChar;
begin
hWebslin := FindWindow(nil,'webslin.exe'); // Get webslin.exe main window handle by title (you can also use other methods such as EnumWindows or GetWindowThreadProcessId)
if hWebslin <> 0 then // If webslin.exe main window handle is valid
begin
hStringGrid := FindWindowEx(hWebslin,0,nil,'Tstringgrid'); // Get StringGrid handle by class name (you can also use other criteria such as title or ID)
if hStringGrid <> 0 then // If StringGrid handle is valid

for ColIndex := 0 to ColCount -1 do // Loop through all columns in last row
begin
CellTextLength := SendMessage(hStringGrid,GM_GETCELLTEXTLENGTH ,RowIndex * ColCount + ColIndex +1 ,0); // Get cell text length by row and column index (note that index starts from one)
GetMem(CellTextBuffer ,CellTextLength +1); // Allocate cell text buffer memory space (note that one extra byte is needed for null terminator)
SendMessage(hStringGrid,GM_GETCELLTEXT ,RowIndex * ColCount + ColIndex +1 ,LPARAM(CellTextBuffer)); // Get cell text by row and column index and store it in buffer
ShowMessage(CellTextBuffer); // Show cell text (you can also do other things with it)
FreeMem(CellTextBuffer); // Free cell text buffer memory space
end;
end;
