vb.net - vb .net using excel automation to paste data into opened workbook -


is possible paste data opened worksheet using office automation vb.net? (i done using oledb slow.)

        dim folder string = "c:\users\gm1\desktop\"         dim filename string = "raw2eng.xlsx"         dim connectionstring string = "provider=microsoft.ace.oledb.12.0;data source=" & folder & "\" & filename & ";extended properties=""excel 12.0;hdr=yes;"""         dim myconnection new oledbconnection(connectionstring)          myconnection.open()         dim cmd1 new oledbcommand         cmd1.connection = myconnection         cmd1.commandtext = "drop table [sheet2$a1:e1027]"         cmd1.executenonquery()          cmd1.commandtext = "create table [sheet2$a1:e1027] (hiresangle float, ch2 float, ch4 float, ch5 float, ch6 float)"         cmd1.executenonquery()          j integer = 0 trimmedsegmentsize - 1             sb = new stringbuilder             sb.append("insert [sheet2$a" & 1 & ":e" & j + 1 & "] (hiresangle, ch2, ch4, ch5, ch6) values ( '")             sb.append(eng(i, j, 0)) : sb.append("' , '")             sb.append(eng(i, j, 1)) : sb.append("' , '")             sb.append(eng(i, j, 2)) : sb.append("' , '")             sb.append(eng(i, j, 3)) : sb.append("' , '")             sb.append(eng(i, j, 4)) : sb.append("' )")             cmd1.commandtext = sb.tostring             cmd1.executenonquery()         next         myconnection.close()

oledb way faster automation. show code, may there problem.

[edit] if want use automation (because want keep workbook opened), may read article : how transfer data excel workbook using visual basic .net
