Title: Export contents of DBGrid to Excel or ClipBoard
Question: I've been asked a quite a few times by the users if it would be possible to see the contents of a grid in excel because they want to do additional operations and not mess with the DB.
Answer:
The example dbgrid (DBGrid1) has a popup menu connected that allows to select the options "Send to Excel" and "Copy"
// NOTE: this method must include the COMObj, Excel97 units
// UPDATE: if you use Delphi 4 you can replace xlWBatWorkSheet with 1 (one)
//-----------------------------------------------------------
// if toExcel = false, export dbgrid contents to the Clipboard
// if toExcel = true, export dbgrid to Microsoft Excel
procedure ExportDBGrid(toExcel: Boolean);
var
bm: TBookmark;
col, row: Integer;
sline: String;
mem: TMemo;
ExcelApp: Variant;
begin
Screen.Cursor := crHourglass;
DBGrid1.DataSource.DataSet.DisableControls;
bm := DBGrid1.DataSource.DataSet.GetBookmark;
DBGrid1.DataSource.DataSet.First;
// create the Excel object
if toExcel then
begin
ExcelApp := CreateOleObject('Excel.Application');
ExcelApp.WorkBooks.Add(xlWBatWorkSheet);
ExcelApp.WorkBooks[1].WorkSheets[1].Name := 'Grid Data';
end;
// First we send the data to a memo
// works faster than doing it directly to Excel
mem := TMemo.Create(Self);
mem.Visible := false;
mem.Parent := MainForm;
mem.Clear;
sline := '';
// add the info for the column names
for col := 0 to DBGrid1.FieldCount-1 do
sline := sline + DBGrid1.Fields[col].DisplayLabel + #9;
mem.Lines.Add(sline);
// get the data into the memo
for row := 0 to DBGrid1.DataSource.DataSet.RecordCount-1 do
begin
sline := '';
for col := 0 to DBGrid1.FieldCount-1 do
sline := sline + DBGrid1.Fields[col].AsString + #9;
mem.Lines.Add(sline);
DBGrid1.DataSource.DataSet.Next;
end;
// we copy the data to the clipboard
mem.SelectAll;
mem.CopyToClipboard;
// if needed, send it to Excel
// if not, we already have it in the clipboard
if toExcel then
begin
ExcelApp.Workbooks[1].WorkSheets['Grid Data'].Paste;
ExcelApp.Visible := true;
end;
FreeAndNil(ExcelApp);
DBGrid1.DataSource.DataSet.GotoBookmark(bm);
DBGrid1.DataSource.DataSet.FreeBookmark(bm);
DBGrid1.DataSource.DataSet.EnableControls;
Screen.Cursor := crDefault;
end;
well those are my $2c.
please post if you have comments or it could be better written.
thnks..
