vb6 - Link ActiveX to Excel -


hope can help!

i programming in vb6 , trying write activex control indicator. indicator should change color relative excel open workbook cell being true or false. indicator should auto updating i.e. indicator needs link live excel cell.

i can place several of indicators c/w links different cells on userform. workbook opened , tested in userform , object references set ok.

i can't figure out how link indicator excel cell.

this part of larger project trying. other control such bargraphs, switches etc. added if can first 1 working.

thanks in advance

you need first add reference microsoft excel x.x library in control's references.

next, should add private module level variable of type excel.worksheet, , declare withevents, e.g.

private withevents m_oworksheet excel.worksheet

you should create property set procedure called worksheet sets variable.

then should add code change event, e.g.

private sub m_oworksheet_change(byval target range)     if target.column = 1 , target.row = 2 ' m_oworksheet.range("a2")         'do coding here     end if end sub

obviously, .column = 1 , .row = 2 replaced cell coordinates interested in. used coordinates "a2", found objects returned m_oworksheet.range("a2") cannot directly compared target object, e.g.

if target m_oworksheet.range("a2")

i tried extract cell reference "a2" target, can't seem find way it, unless write function conversion of column/row string reference.

note previous answer provided very wrong, since testing

if target = m_oworksheet.range("a2)

... worked because default value properties identical. fall on if changed cell had same value "watched" cell.
