Crystal accepts data in many forms. Personally in like to collate the data into a typed dataset and then pass the dataset to crystal.
Writing reports with Crystal is a big topic all of its own, and there are many good books on the subject.

You should try to Create Report by using PrintDocument Control.
Because CRYSTAL REPORT and Report Viewer are not sutable for VB 6.
Secondly you can use Microsoft Access Report Viewer for Generating Report.

hi... im trying to convert a code according to my list.. my list in a table are:
<folder> <portal>
C0014 SEJATI
BRT04 BRT01
MBS01 MBSB
MBS02 MBSB
C0015 SEJATI

convertCoop(coop, portal)
error "Value cannot be null.Parameter name: dataSet"
what does it mean?
Private Sub convertCoop(ByVal coop As String, ByVal portal As String)
Dim conn1 As New SqlClient.SqlConnection("Data Source=10.0.0.70;User ID= sysadm;Password=sysadm;Initial Catalog=SPGA_Latihan;Persist Security Info=True;")
Dim comm As SqlClient.SqlDataAdapter = Nothing
Dim ds As DataSet = Nothing
Try
Dim strSQL2 As String = "SELECT folder, portal FROM kodPortal WHERE folder ='" & coop & "'"
conn1.Open()
comm = New SqlClient.SqlDataAdapter(strSQL2, conn1)
comm.Fill(ds, "kodPortal")
portal = ds.Tables(0).Rows(0).Item("portal")
conn1.Close()
Catch ex As Exception
MsgBox(ex.Message)
Finally
If Not conn1 Is Nothing And conn1.State = ConnectionState.Open Then
conn1.Close()
End If
conn1 = Nothing
comm = Nothing
End Try
End Sub

It means you have no idea what you're doing. At a guess, it means that the parameter cannot be null. so, try Dim ds as DataSet = new DataSet()
From MSDN "[Visual Basic, C#, C++] The following example uses the SqlCommand, SqlDataAdapter and SqlConnection, to select records from a database, and populate a DataSet with the selected rows. The filled DataSet is then returned. To accomplish this, the method is passed an initialized DataSet, a connection string, and a query string that is a Transact-SQL SELECT statement."
Did you bother to read the docs. The dataset needs to be initialised. You're getting an error telling you the same thing.

whether you check the dataset contain any row? First create a instance of dataset.

hey i have created my own custom property
the property is of type collection ,
it displays a form which allow the user to add a list of images and strings,
it stores the data in a collection ,
my problem is , i have noticed that after adding items to the collection at design time , there is no code generated in the .Designer file of the form and there for when i close the for / save it and reload it , all the items that i added to my custom property are gone.
my question , what did i miss here ? how do i make my custom property generate code at the .designer file for the items i have added to my property?
thanks.

You have to tag the public properties you want the designer to write code for with the DesignerSerializationVisibility attribute. Like this:
DesignerSerializationVisibility(DesignerSerializationVisibility.Visible) _
Public Property MyControlProperty() as Integer
....
End Property
You can find the docs on the DesignerSerializationVisibility Attribute class here[^].

Your settings is a collection of arraylists ? Are you sure ?

i has about 20 different arraylist in it, just trying to remove a section out of each 1

Perhaps My.Settings is not a collection you can for each over, you can only access the values by name ? Or does My.Settings have a property that IS a collection, which you could use ?

well i had a look and could not find anything, sorry to ask this but can you give me a little more of a hint?

I am on my Mac, I'd have to go and boot windows to have a dig around for you. I really don't know what My.Settings returns.
The Property Grid can iterate over your settings, so there has to be a property. Just hit . after My.Settings and look through, there's got to be something, otherwise your other option ( as it appears to be a machine generated class from a config file ) is to use reflection.

Hi , I’m doing a little experiment.
I created procedures that can create new forms at run time.
------------------------------------------
Private Sub createForms()
Dim i As Integer
For i = 1 To 10
newform = New Form
newform.Name = "Form_" + i.ToString
newform.Show()
Next
End Sub
------------------------------------------
Now I want to move those forms on the screen, close them one by one, change size etc.
I cant find the way to acces the forms that I just created. I tried using newform.Name property but it dosent work.
Any suggestions???
Thanks

Thanks

The newform variable can't be accessed outside of the FOR loop. I recommend making the form a global variable.
How many bytes of text have I typed in my lifetime??? Man, I wish I kept track...

But, he's creating 10 of them, not just one.
