DbGrid控件的標題欄彈出菜單
PRocedure TFrmOrderPost.DbgOrderPostMouseDown(Sender: TObject; Button: TMouseButton; Shift: TShiftState; X, Y: Integer);
var
  CurPost:TPoint;
begin
  GetCursorPos(CurPost);//獲得鼠標當前坐標
  if (y<=17) and (x<=vCurRect.Right) then
  begin
    if button=mbright then
    begin
      PmTitle.Popup(CurPost.x,CurPost.y);
    end;
  end;
end; 
//vCurRect該變量在DbGrid的DrawColumnCell事件中獲得
{procedure TFrmOrderPost.DbgOrderPostDrawColumnCell(Sender: TObject;const Rect: TRect; DataCol: Integer; Column: TColumn; State: TGridDrawState);
begin 
  vCurRect:=Rect;//vCurRect在實現部分定義
end;} 
如何將幾個DBGRID里的內容導入同一個Excel表中?
在軟件實際制作中,為節省開發成本和開發周期,一些軟件人員通常會吧DBGrid中的數據直接導出到Excel表中,而先前能看到的函數僅僅只能在WorkBook的一個Sheet中導入數據,不支持多Sheet!。
單元應用:
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls, DB, DBTables, Grids, DBGrids, ActiveX, ComObj,
Excel2000, OleServer;
測試環境:
OS:Win2k Pro;Excel2k;Delphi6.0
源程序:
{
功能描述:把DBGrid輸出到Excel表格(支持多Sheet)
設計:CoolSlob
日期:2002-10-23
支持:CoolSlob@163.com
調用格式:CopyDbDataToExcel([DBGrid1, DBGrid2]);
}
procedure CopyDbDataToExcel(Args: array of const);
var
  iCount, jCount: Integer;
  XLApp: Variant;
  Sheet: Variant;
  I: Integer;
begin
  Screen.Cursor := crHourGlass;
  if not VarIsEmpty(XLApp) then
  begin
    XLApp.DisplayAlerts := False;
    XLApp.Quit;
    VarClear(XLApp);
  end;
  try
    XLApp := CreateOleObject(‘Excel.application‘);
  except
    Screen.Cursor := crDefault;
  Exit;
  end;
  XLApp.WorkBooks.Add;
  XLApp.SheetsInNewWorkbook := High(Args) + 1;
  for I := Low(Args) to High(Args) do
  begin
    XLApp.WorkBooks[1].WorkSheets[I+1].Name := TDBGrid(Args[I].VObject).Name;
    Sheet := XLApp.Workbooks[1].WorkSheets[TDBGrid(Args[I].VObject).Name];
    if not TDBGrid(Args[I].VObject).DataSource.DataSet.Active then
    begin
      Screen.Cursor := crDefault;
      Exit;
    end;
    TDBGrid(Args[I].VObject).DataSource.DataSet.first;
    for iCount := 0 to TDBGrid(Args[I].VObject).Columns.Count - 1 do
      Sheet.Cells[1, iCount + 1] := TDBGrid(Args[I].VObject).Columns.Items[iCount].Title.Caption;
    jCount := 1;
    while not TDBGrid(Args[I].VObject).DataSource.DataSet.Eof do
    begin
      for iCount := 0 to TDBGrid(Args[I].VObject).Columns.Count - 1 do
        Sheet.Cells[jCount + 1, iCount + 1] := TDBGrid(Args[I].VObject).Columns.Items[iCount].Field.AsString;
      Inc(jCount);
      TDBGrid(Args[I].VObject).DataSource.DataSet.Next;
    end;
  end;
  XlApp.Visible := True;
  Screen.Cursor := crDefault;
end; 
 怎樣在DbGrid的左邊,實現像EXCEL那樣的自動編號?這些編號與表無關
unit Unit1;
