Changing Database location
I need to be able to change the database location in Crystal 10, in vb code I have searched for solutions here
and have found one that would be just right for my problem.
I get the following error when I try to print a report on the mySQL data base which is located on the web.
Run-time error '-2147189180(80047e44)'
The table 'tblproject' could not be found.
this is the code I am using:-
Dim crx As New CRAXDDRT.Application ' creates an instance of the Crystal Report application
Dim rpt As CRAXDDRT.Report 'will hold the report object later
Dim i As Integer
Set rpt = crx.OpenReport(strReport) 'asks the crystal application to open a report file named C:\blah\CoverPage.rpt and returns it to rpt
rpt.DiscardSavedData 'throws out any saved data the report might already have
For i = 1 To rpt.Database.Tables.Count 'the database.tables collection is all the tables used by the report
------------------ The following Line Gives The Error --------------------------
rpt.Database.Tables.Item(i
'SetTableLocation sets where Crystal will look for that table. g_objcon is just an ADO connection I've already opened on my dataset
'the connectionstring could simply be specified here, e.g. "provider=SQLOLEDB;server=
'I use theg_objcon.connectionstri
'connection is open, I simply use it's connection string to avoid repeating the logic to choose which database.

Although not related Using the same code but the connect string below I have a strange problem with the same code but attempting to print a report from a local Access database for each table in the report it asks for database location ans user and password the connect string is:-
myDBConnectString = "provider=Microsoft.Jet.OL
username and password are not required as the program generates the data

Who is Participating?
well yes but I am using the code twice in different forms, one form for the mysql database, and a different one for the Access.
In Access:
But essentially if I create a report and then place it in a different location the the problem arises for each table in the report it asks for user name and password to be entered.
In mysql:
The mysql problem is that it does not seem to find the first table in the report as it falls over at that point I cant say it wont find any other table.

ok will try that, am I correct inthinking that I dont need to use the connect string and should I just use the code as you have written it except use my database name.
I think so. That should work for Access. If MySQL has the same type of file then it may work for that also.
If you are trying to use 1 report against 2 different types of databases that won't work.

Yes thank you it worked for the access database, now all we need to do is to get the mysql working, this is important because most of the reports will be run for there.
Hi
I recieved an email with a possible solution, but have lost it I thought the solution worked but have just tried it against a second database and the report printed the data from the original database, this is the code I am now using
Private Sub Form_Load()
Dim App As New CRAXDDRT.Application
Dim rpt As Report
SetReportConnection (strReport) ' strReport is the path to the file and the report name
Set rpt = App.OpenReport(strReport)

my appoligies I could not find the thread that your code came from and as I could not get the code as presented to work. I did mention that I couldnt find the thread and in the end did not use the code although the ideas from the code did come in usefull. if it is possible please divide the points between the two of them

When changing the Access database, is it using the same MDW file?
Try it this way for Access
rpt.Database.Tables(1).Loc
Also fo the user/password (default user)
'sets the database password enabling the report to connect
rpt.Database.Tables(1).Set
