In SMExport I added two important features:
- TSMExportToXLSX component supports the merge. You may export a few datasets on different sheets in same xlsx-file
- new TSMExportToExcelXML component generates the Excel XML file. Low memory usage and high speed for large datasets
Today I added the new feature in SMExport – to create the xml file from dataset which is compatible with ADO.NET.
Small sample code:
smeXML := TSMExportToXML.Create(nil); try smeXML.DataSet := ClientDataSet; smeXML.ColumnSource := csDataset; smeXML.FileName := ADOXMLFileName; smeXML.AddTitle := True; smeXML.Format := xmlADO; smeXML.XMLTags.RowTag := 'z:row'; smeXML.DataFormats.CustomDateTimeFormat := 'yyyy-mm-ddThh:nn:ss'; smeXML.Execute; finally smeXML.Free; end;
Today I added the new feature for TSMExportToHTML component – the possibility to generate the html file with embedded images. Unfortunately the old IE (5/6) do not support this feature but FireFox, Opera, Safari will open the file without any problem

Note: large images will not displayed due some limits in browser for encoded string
In SMExport I added the new component to support the JavaScript Object Notation
The format of generated samples are available at http://www.json.org/example.html
For example:
{
“RECORD”: {
“Species No”: 90020
“Category”: “Fish”
“Common_Name”: “CommonFish 828″
“Species Name”: “Fish 275″
“Length (cm)”: 50
“Length_In”: 19,6850393700787
}
}
The dates encoded as the number of milliseconds since January 1st 1970. See the topic for this subject at
http://weblogs.asp.net/bleroy/archive/2008/01/18/dates-and-json.aspx
The binary values encoded in Base64 (same as in xml)
Created the new TAction for export support. Will be included in next SMExport
