DbGrid控件的标题栏弹出菜单
procedure TFrmOrderPost.DbgOrderPostMouseDown(Sender: TObject; Button: TMouseButton; Shift: TShiftState; X, Y: Integer);
var
CurPost:TPoint;
begin
GetCursorPos(CurPost);//获得鼠标当前坐标
if (y<=17) and (x<=vCurRect.Right) then
begin
if button=mbright then
begin
PmTitle.Popup(CurPost.x,CurPost.y);
end;
end;
end;
//vCurRect该变量在DbGrid的DrawColumnCell事件中获得
{procedure TFrmOrderPost.DbgOrderPostDrawColumnCell(Sender: TObject;const Rect: TRect; DataCol: Integer; Column: TColumn; State: TGridDrawState);
begin
vCurRect:=Rect;//vCurRect在实现部分定义
end;}
如何将几个DBGRID里的内容导入同一个EXCEL表中？
在软件实际制作中，为节省开发成本和开发周期，一些软件人员通常会吧DBGrid中的数据直接导出到Excel表中，而先前能看到的函数仅仅只能在WorkBook的一个Sheet中导入数据，不支持多Sheet！。
单元应用：
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls, DB, DBTables, Grids, DBGrids, ActiveX, ComObj,
Excel2000, OleServer;
测试环境：
OS：Win2k Pro；Excel2k；Delphi6.0
源程序：
{
功能描述：把DBGrid输出到Excel表格（支持多Sheet）
设计：CoolSlob
日期：2002-10-23
支持：CoolSlob@163.com
调用格式：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;
怎样在DbGrid的左边，实现像EXCEL那样的自动编号？这些编号与表无关
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
Grids, DBGrids, StdCtrls, Buttons, Db, DBTables, ExtCtrls, jpeg;
const ROWCNT=20;
type
tmygrid=class(tdbgrid)
protected
procedure Paint;override;
procedure DrawCell(ACol:Integer;ARow:Integer;ARect:TRect;AState:TGridDrawState);override;
public
constructor create(AOwner:TComponent);override;
destructor destroy;override;
end;
TForm1 = class(TForm)
BitBtn1: TBitBtn;
DataSource1: TDataSource;
Table1: TTable;
procedure BitBtn1Click(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
mygrid:tmygrid;
implementation
{$R *.DFM}
{tmygrid}
constructor tmygrid.create(AOwner:TComponent);
begin
inherited create(Owner);
RowCount:=ROWCNT;
end;
destructor tmygrid.destroy;
begin
inherited;
end;
procedure tmygrid.Paint;
begin
RowCount:=ROWCNT;
if dgIndicator in options then
ColWidths[0]:=30;
inherited;
end;
procedure tmygrid.DrawCell(ACol:Integer;ARow:Integer;ARect:TRect;AState:TGridDrawState);
begin
inherited;
if (ARow>=1) and (ACol=0) then
Canvas.TextRect(ARect,ARect.Left,ARect.Top,IntToSTr(ARow));
end;
procedure TForm1.BitBtn1Click(Sender: TObject);
begin
mygrid:=tmygrid.create(Self);
mygrid.parent:=self;
mygrid.left:=0;
mygrid.top:=0;
mygrid.Height:=300;
mygrid.DataSource:=DataSource1;
end;
end.
