Sim,
Crie um formulário tabular que ficará mais fácil a visualização das alterações. Crie também um relatório que servirá de base para a criação do documento em PDF.
Baixe os arquivos da internet: StrStorage.dll e dynapdf.dll
Coloque esses arquivos na pasta onde está seu arquivo .mdb ou .accdb
Coloque uma caixa de texto em seu formulário com a fonte de controle ="NomedoSeuRelatorio"
Dê um nome a esta caixa de texto: lstRptName
Código do botão que gerará o arquivo em PDF:
No evento Click de seu botão no formulário:
Dim blRet As Boolean
blRet = ConvertReportToPDF(Me.lstRptName, vbNullString, _
Me.lstRptName.Value & ".pdf", False, True, 0, "", "", 0, 0)
Por fim, crie um módulo que contenha a função ConvertReportToPDF:
Dê o nome de : modReportToPDF
Cole este código que eu acredito que seja do Stephen Lebans no ambiente de código deste módulo:
Não fique pasmado pois ele é bem longo.
