Raul Team Elevate | Just a guess but check your files (do a text search in both wbf and wbs
file ) for the "parent" string. In my case i think i did not notice my focus was on property list and typed something funny there so a component property ended up with invalid value - EWB did not complain until compile time. Unable to re-produce though. Raul On 3/14/2013 7:17 PM, Paul Waegemans wrote: > I receive without any reason that I could imaging the errorcode hereby attached. > |

Paul Waegemans IMS bvba | Tim,
Thanks but as I just started with my project I did a restart from the beginning. My project is the following: I have a DBISAM database who is already in use in a back office application that I developed in Delphi. Now I want to make a web application where my contacts can login (name+pasword) and can in first instance update their personal information (for ex telephone, adress email) and see the history of the seminars on which he participated. The next step will be that the contact can register ONLINE for the next seminars. So the login is already working properly but I have a problem to show the history of seminars (see attached error) procedure TFrmAanmelden.BtnLoginClick(Sender: TObject); begin ZoekContacten.Params.Clear; ZoekContacten.Params.Add('Volnaam='''+ TRIM(EdtZoekVolnaam.text)+''''); ZoekContacten.Params.Add('Paswoord='''+ TRIM(EdtZoekPaswoord.text)+''''); Database.Load(ZoekContacten); PnlLogin.visible:=false; Label1.caption:='Welcome '+TRIM(Zoekcontacten.Columns['Volnaam'].asstring); PnlInfo.visible:=true; PnlInfo.top:=0; PnlInfo.width:=FrmAanmelden.width; GrdSeminars.width:=PnlInfo.width; Seminars.Params.Clear; Seminars.Params.Add('Contact_ID='+ ZoekContacten.Columns['Contact_ID'].asstring); Database.Load(Seminars); end; With the code above I have the following problemes: label1.caption is not shown properly Dataset Seminars gives ERROR (see hereby) If I change the code in: Seminars.Params.Add('Contact_ID='+ TRIM(IntToStr(ZoekContacten.Columns['Contact_ID'].asinteger))); Then I have no ERROR but no records in the Grid !?!? I must be missing something basic ... Attachments: error.jpg |

By Tim: << You must always remember that the web browser environment is *always* asynchronous relative to events, especially events that require server requests/responses like the commit operation. >> That's why you get an error when you are trying to use values of your first query in a second query. Use the AfterLoad event handler of your dataset for code that uses values from this dataset. That makes sure that the resulting records have been returned by the server. Ui |
