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.

Sql Server - SSRS Code Shared Variables And Simultaneous Report Execution?

Dec 28, 2009

I've found out that if two instances of an SSRS report run at the same time, any Code variables declared at the class level (not inside a function) can collide. I suspect this may be the cause of our report failures and I'm working up a potential fix.The reason we're using the Code portion of SSRS at all is for things like custom group and page header calculation. The code is called from expressions in TextBoxes and returns what the current label should be. The code needs to maintain state to remember what the last header value was in order return it when unknown or to store the new header value for reuse

.net - SSRS Report Called From ReportViewer Control Displays No Data In The Report When Called With A Parameter

Apr 11, 2012

Can you look at my coding and let me know what I'm missing or doing wrong?I have a SSRS report that is called from a ReportViewer control and the ProcessingMode for this control is Remote. The report also has 1 parameter in it's DataSet.In the code I placed a MsgBox to make sure the code is finding the parameter and returning the parameter name. I am trying to stick the value of 10 into the parameter for playerID 10. Data for this player does exist.

I believe I need to add some more code to make this work but I'm not sure what else to add.

When the code executes the report is displayed but no data is shown in the report.

.net - SSRS Report Expression - Null Being Treated Like Zero?

Apr 11, 2012

Consider this SSRS value expression :=IIF(First(Fields!MyCol.Value, "MyDataSet")=0, "yes", "no")

MyCol is a Nullable column. I want "yes" to be output only when MyCol equals 0. The code above correctly evaluates to "yes" when MyCol is 0. However, it also evaluates to "yes" when MyCol is Nothing (i.e. NULL in SQL Server). Is this expected behavior ?

I had to resort to the following longer expression to get the desired result :

=IIF(Not(First(Fields!MyCol.Value, "MyDataSet") is Nothing) And First(Fields!MyCol.Value, "MyDataSet")=0, "yes", "no")Is there a shorter version of this which also works ?

Asp.net - SSRS Reporting Loads Slowly The 1st Report

Apr 30, 2012

I have a website(asp.net) which displays ssrs reports. Howevery everytime that I try to run the report from the website it takes about 2 min to load, but if I click on the report again , it will load up in seconds. I have tried to run a query that is used by the report and I get the results in second as well.

Is there any configuaration that I need to change or any tsql code that I need to add?

I have gone through to solutions provided here on stackoverflow but still had no luck.

String Parameter With Space In Between Passing To SSRS Report?

Nov 2, 2010

my users to view, send (via email), export SSRS reports. I have set up date parameter boxes with calendar drop down and they are able to send via email a URL link that would either display the report via ReportViewer or send a link that would let then view the report in Excel or PDF. This is working just fine. Now I just added another report with a procedure prompt using a text box. Report works fine when I run it in SSRS. If I enter say carotid stent, it displays all records that have the word "carotid stent" in the procedure name field. Now, when I added code using VS 2005 to accommodate this new parameter, here's my code -

ProcedureName = txtProcedureName.Text
msg.Body = "Please click on the URL link to view the report - " + Chr(13) + Chr(10) + "http://SERVERNAME/ReportServer/Pages/ReportViewer.aspx?%2fReports%2f" + ReportName +

Local SSRS Report (.rdlc) With Object Data Source?

Apr 15, 2011

i created more projects using ReportViewer 2005 and 2008 in local processing mode than I can count on my hands. All Visual Studio 2005 or 2008 ASP.NET web forms projects. I always used some flavor of Object data source for the reports.Tonight, I attempted to add the same functionality to a Visual Studio 2010 MVC 2 project and am failing miserably. First, the Add New Item > Reporting > Report is now a 2008 RDLC and not a 2005 RDLC report. Secondly, when trying to add a DataSet, my usual method of create a data proxy class with static methods that return IEnumerables(Of Stuff) will not show up as sources in the DataSources drop down

Thirdly, my only option is to add a Database connection. There is no "Object Data Source" to pick from: Like I kind of alluded to, I have no problems whatsoever actually rendering a report using the ReportViewer control. What I can't do is figure out how set up a Data Source in these new-fangled 2008 reports with Visual Studio 2010 so that I can pump a list of domain objects into the ReportViewer and display the report.

UPDATE: With some more research, I've found that MVC projects do not allow object data sources to be used within them. One solution for my issue is to create a separate project in the solution -- a web application, a service, or even just a class library, to add the report to and design it accordingly.'m still looking for alternatives here, so don't run away too fast!

Asp.net - Unable To Load Control With Report Viewer (for SSRS 2k5) And Vs2010?

.net - Optimization With Visual Studio Or A Logic Bug?

Feb 3, 2011

I have an small physics toy application I am developing. It works fine except the particles will not push each other away, only pull towards, I debugged that sub going through it command by command and realised the value 'H' would not change, what ever it was set to during the first pass through the sub is what it kept, the only way to change this value is to manually set it i.e 'h = 1'. Once the calculation is redone on the 'H' value it resets to what it was previously, even though the x1,y1,x2,y2 are all different, thus meaning H should be different.

I think it is me that has made a mathematical mistake somewhere, but I cannot see where it is. I need a fresh pair of eyes to look over my work. Please let me know if you find anything.

Does anyone know of any kinds of optimization I can do so that I can scroll faster? Like what is the DataGrid doing when you scroll? Does it repaint every screenful? Does it validate every row? It seems like it is doing something unneeded when a user scrolls.

Jul 3, 2011

This is my first time writeing a program and i am stuck. i am just looking for were i should go next. i can't figure out how to write in code for the days in the getDay function.

Write a program that computes the cost of a long-distance call. The cost of the call is determined according to the following rate schedule:

a. Any call started between 7:00 A.M. and 9:00 P.M., Monday through Friday, is billed at a rate of $0.30 per minute.

c. Any call started on a Saturday or Sunday is billed at a rate of $0.10 per minute.

The inputs will consist of (1) the day of the week, (2) the start/end time of the call, and (3) the length of the call in minutes. The output will be the cost of the call. Input will come from the user and outputs will be displayed via the console window.
