  hi pete
  i dont remember what report demos are available
  in free report
  but see if you have the printable2 demo.
  when using with a cross data band in conjunction with a master databand
  you need to connect mdband to table/query through frdbdataset
  and the cross databand to an fruserdataset 1 for each horizontal band it crosses.
  mhband.mdband
  the memo containing [Cell] derives its values from the ongetvalue event handler
  of the report component, as does the memo containing [header]
  the range of the fruserdatasets is set to recount and the count value is set to fieldcount of the table.
  that is the basics there are some other requirements shown in the demo
  ways to get field sizing etc.
  Once you understand this demo crosstabs using table/queries is a snap.

  Hi
  
  I saw that the demo was somehow building the report at runtime with code. Is that absolutly necessary? I have not got a clue what the code is doing with the fruserdataset's. Is there a tutorial I could follow somewhere that explained what I was doing and why? The documentation seems sparse, is it better with the fast report package? Am I missing something?
  
  Thanks
  Pete

  Hi
  
  Further to my last post, I have looked and steped through the demo. Am i right in thinking that the fruserdataset is basically being used as a 'counter' to count from 0 to the number of fields in the table/query? Is this because the rangeEnd property is set to reCount?
  
  That is what appears to be happening in the demo. However, in the example I am working on although rangeEndCount is being set to 2, the value of fruserdataset.recNo doesnt appear to change in the ongetvalue event handler.
  
  Am I on the right track? Any ideas why my recNo is not being incremented?
  
  Thanks
  Pete

  Hi Pete
  do you have the demo i mentioned.
  if the answer is yes
  try this with the demo
  select the table object open the fields editor for the table delete the fields.
  now set the table component's databasename to your dbname and the tablename to your table name. open the fields editor for the table again and add all the fields of your table.
  run the demo to see the output.
  what you are probably missing is setting the datasource properties of the cross databand. you need to set the fruserdataset for each of the bands shown in the left hand pane.
  Also look at the events that are used in the reportcomponent, pay close attention.
  the onbefore print event is not written by dblclicking the event and adding code.
  it is just has an onenterrectangle procedure assigned to it.

  Hi
  
  Thanks for this help. I dont think I have the printable2 demo, I have a prntable but it doesnt have an onbefore print event.
  
  You were write about me not having assigned the datasource properties of the cross databand to be the fruserdataset. My report now shows values! However, it is only showing one record's results rather than all the results
  
  Just to explain further; I have two tables, linked by a field called adminNo, the second table has field called 'result'. It is a one-to-many relationship. So there will be two 'result' values for each adminNo. So my first table might have data:
  adminNo fname sname
  001 fred smith
  
  And my second table:
  adminNo result
  001 78
  001 94
  
  and I want my report to be:
  adminNo fname sname result1 result 2
  001 fred smith 78 94
  
  but what i seem to be getting is:
  adminNo fname sname result1
  001 fred smith 78
  
  Is it possible to do what I want?
  
  Thanks again for your help

  further to my last post! I have finally found frdemo and tracked down a doc4.frf that appears to be a cross tab report. I was saving my report in the dfm, not sure what the advantage of saving the report as a frf and then loading it is?
  
  Anyway I notice that that has a cross header, and an object with row 1[Master position] but i can find no reference to this in either the manual (fr_eng.doc: report generator fastReport v2.3), the help or the units! What am i meant to do with it?
  
  Sorry for so many questions.....

  Hi since you don't have the demo i mentioned ,my fault, it doesn't come with free
  report, i'll try to work with you on the one you do.
  The difference between storing a report in dfm and storing ias an frf.
  if you store in dfm, you need 1 report component for each report, and if you make design changes you must send a new exe,file to your end user.
  if you store as a .frf, you can make design changes and never have to recompile the app., just send new frf and you wont have a huge .exe file.
  
  Looking at the memo that contains
  
  row 1[Master position]
  row 1 is just text and the altkey# used to get superscript 1.
  master position is a variable in the datadictionary.
  in design window filemenu-datadictionary to see the variables used in the report and what they are related to. Notice that the "Cell" vaiable has an expression
  attached
  The masterdata data band and cross data bands are set to virtual data sets of n records to suit what we want. if you change the count then the expression in cell variable and others, must be changed to suit.
  This is a totally self-contained report and uses no outside code.
  
  When working with data things change considerably
  the masterdata row connects to a frdbdataset and the programmer becomes responsible for retreiving values and positioning of the cross data bands datasource
  by passing out info to delphi, row = [Line#]. column := column =[Col#], using either report component events or on userfunction event handlers and userfunctions in the obp event of a report band.
  
  Note it is probably easier to supply data from a joined query to retieve
  one dataset with fields ordered by grouping conditions. than trying to control 2 or 3 datasets.
  In Full version there is a cross tab object which makes this process much easier to deal with.
  hope this Helps.
