Crystal Report And Code Optimization?
Jul 24, 2009
Ok, the error I'm getting is "Load Report Failed" and it happens when I need to load a large number of crystal ReportDocument objects. I've searched on this, and there is a property in the registry that you can change to -1 and it allows to load more, however I'm still getting the error, just after I get about twice as many documents loaded.
The report is basically a one page document (for each client in the database with an interest charge). It displays the amount of interest charged, and other information pertaining to the charge. These documents are basically printed out and mailed to the client.
I created a "Print Preview" screen which has a CrystalReportViewer object, and an ArrayList property. The ArrayList property has an array of all reports, and there are next and back buttons to browse through each report. Once they are satisfied, they will print them all out, and I can dispose of the objects.
The solution for this, from everywhere I've seen, is to "Dispose the object after you are done with it". My problem is that I can't dispose it until they are finished with the print preview screen.
Is there a better way to go about this that won't require too much time to code (we are already over the deadline on this project) or a simple solution to get past the ReportDocument limit? Right now it is erroring on report 150., There are 180 records (as of today) that need to be loaded.

I came across the following code recently and would like to optimize it:Public Shared Function ComputeLabel(ByVal Action As Integer, ByVal Flag1 As Boolean, ByVal Flag2 As Boolean) As String
Dim Prefix As String = ""
If Flag2 Then
Prefix = "Conditional "

I have a Crystal Report that I am trying to access thru my VB.Net app. My problem is that I keep getting a "Database Logon" prompt (see screenshot). My code is below and I think I might have more than I actually need. I created the report from with the VS 2008 IDE.
Private Sub rptSingleWorkOrder()
Try
strSQL = "Select A.productName, " & _
"A.productDesc, " & _
[code]....
By the way, this code runs cleanly completely thru from the time the procedure is called until it exits.

The following code takes a timeframe in minutes since midnight and creates an array with minutes pr hour. But, it's slow. Any better suggestions out there? (no, changing language is not an option :-) )
Const clDeparture As Long = 123
Const clArrival As Long = 233
Dim lHour As Long
Dim lMinute As Long
Dim alHour(25) As Long

I'm wondering if you know if there is a better way to write this code in order to speed it up. It has several blocks of if statements filling arrays, like this:
row0: If x < b(1, 1) Then a1(i, j + 1) = 0
If x > b(1, 1) And x < b(1, 2) Then a1(i, j + 1) = 30
If x > b(1, 2) And x < b(1, 3) Then a1(i, j + 1) = 60

I plan on designing a Crystal Report, and then calling it through VB.NET code. Will the end-user need a Crystal license in order to use the crystal report part of the program?

I have created an application using vb.net 2008 and for reports Crystal Reports Basic for Visual Studio 2008 but the problem is, when I run the application in another machine away from developing box, I get the Load report failed notice. I don't have any idea on how I should approach this issue. I tried installing the CRRedist2008_x86 and CRRedist2005_x86 but still the problem won't go away.

I want to display the data from the table, column name "Remarks" in report footer but when I try to call the data it doesn't show the remarks. I'm using VB 6 and mdb files as my back end. Is there any command or fundamental that I've missed?

I need advise on how to solve this scenario. I am not sure whether I should use any Report Application such as Crystal Report or I can just simply use datagridview.My scenario:In a new form, a table will show a least 3 columns.
First, ItemID
2nd, Total Quantity Sold for the Current Month
3rd, Total Quantity Sold: Last month
ItemID Current (Nov) October
ABA1 100 85
ABB1 80 90
Hence, I can compare the figure of the current month with the past few month.Right now, I do not have any problems building SQL_String for calculating the Total Qty Sold for the Current month and display it via DataGridView. But I am not sure how to additional column that calculate the Total for the past few month

I am trying to convert a VB6 Data Report (.dsr file) to a Crystal Report through the migration process within Visual Studio. I have read articles that reference adding a Data Report to a Project from Visual Studio 2005/2008 and that it will convert the Data Report to a Crystal Report, but I have not been successful in doing so. Does the VB6 Data Environment need to be converted too? Has anyone been able to do this successfully and if so, how?

how I can reference a report variable in the Report Properties Code Window of a local report? I have tried Variables!Claimant.Value (for a variable called Claimant) but I get an error "Reference to a non-shared member requires an object reference." I have tried qualifying it with Report. and also with the report name in front of it but I get errors with this also.I have the variable CLaimant defined in the Variables section of the Report Properties.
