vb.net - Dataadapter for each datagridview wont work -


i have 3 datagridviews

datagridview1, datagridview2, datagridview3

each datagridview being bind using different data adapters , different bindings

datapter1, dataadapter2, dataadapter3, binding1 binding2 , binding3

'binding dgv1  datapter1.selectcommand = mycmd datapter1.fill(dset, "something") binding1.datasource = dset.tables("something1") datagridview1.datasource = binding1  'binding dgv2  datapter2.selectcommand = mycmd datapter2.fill(dset, "something") binding2.datasource = dset.tables("something2") datagridview2.datasource = binding2  'binding dgv3  datapter3.selectcommand = mycmd datapter3.fill(dset, "something") binding3.datasource = dset.tables("something3") datagridview3.datasource = binding3

when time wanted update datagridview1

dim firstbuilder new mysqlcommandbuilder(me.dataadapter1) me.dataadapter1.update(me.binding1.datasource) me.binding1.resetbindings(false)

it prompts me error that

missing datacolumn 'located in datagridview3' in datatable 'of datagridview3' source column 'located in datagridview3'

i don't see why have error since used different bindings , different dataadapters each datagridview. need fix issue...

i have struggled same issue days years ago... created custom class in end. created separate dataadapters , -commandbuillder each datatable. not sure if efficient way, works:

'1 dataset full db public dbdataset new dataset {.casesensitive = false}  '1 datatable, dataadapter en commandbuilder per table private listof_datatables new list(of datatable) private listof_dataadapters new list(of oledbdataadapter) private listof_command new list(of oledbcommand) private listof_commandbuilder new list(of oledbcommandbuilder)  public sub load_table(tablename string)     'load accesstable dataset     dim sqlstring string = "select * " & tablename.toupper     dim dbcon new oledbconnection(_dbconnstring_full)     dbcon.open()     listof_dataadapters.add(new oledbdataadapter)     listof_command.add(new oledbcommand(sqlstring, dbcon))     listof_dataadapters(listof_dataadapters.count - 1).selectcommand = listof_command(listof_command.count - 1)     listof_commandbuilder.add(new oledbcommandbuilder(listof_dataadapters(listof_dataadapters.count - 1)))     listof_commandbuilder(listof_commandbuilder.count - 1).quoteprefix = "["     listof_commandbuilder(listof_commandbuilder.count - 1).quotesuffix = "]"     listof_dataadapters(listof_dataadapters.count - 1).fill(dbdataset, tablename)     listof_datatables.add(dbdataset.tables(tablename))      'get primary keys     dim ucollist new list(of string)     dim myschema datatable = ctype(dbcon, oledbconnection).getoledbschematable(oledbschemaguid.primary_keys, new object() {nothing, nothing, tablename})     dim columnordinalforname integer = myschema.columns("column_name").ordinal     each r datarow in myschema.rows         ucollist.add(r.itemarray(columnordinalforname).tostring)     next      'set primary keys     dim keycolumn(ucollist.count) datacolumn     index = 0 ucollist.count - 1         keycolumn(index) = dbdataset.tables(tablename).columns(ucollist(index))     next     dbdataset.tables(tablename).primarykey = keycolumn      dbcon.close() end sub public sub update_tables()     dim nradap integer = listof_dataadapters.count     adapterindex = 0 nradap - 1         listof_dataadapters(adapterindex).update(dbdataset.tables(adapterindex))     next end sub

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
