Re: Oracle Data reader with Crystal Report Viewer Ennis Ray Lynch, Jr.3-Jun-09 5:07 Ennis Ray Lynch, Jr. 3-Jun-09 5:07  If you have a databinder then you can automatically create a dataset with the reader. However, creating a data set with a data reader will never be faster than using the data reader alone. A data reader is a fast-forward, read only schema blind cursor (Ok, oracle supports cursor definitios) and is the absolute fastest possible way to retrieve non-bulk data from a database. BTW, Console.WriteLine is slow. One last thing, with Crystal you should be able to bind to a stored procedure to take advantage of the cursor and not require a dataset. Give it a shot.

Actually, i do'nt know how do i assign Oracle data reader as dataset / datasource to crystal report viewer; even is it possible or not, i am not aware of it. I have somewhere read that it is the best way to write the stored procedure to fetch the rows and then call that stored procedure by data reader. This is has been done by me; but now how i go further with this data reader to populate the crystal report viewer. Since dataset consumes a lot chunk of memory on serve i.e. adapter.fill(ds); so i am trying to implement data reader way. I Shall be highly thankful to you for your next valauable replies please. Regards Girish Sharma Re: Oracle Data reader with Crystal Report Viewer Ennis Ray Lynch, Jr.3-Jun-09 5:19 Ennis Ray Lynch, Jr. 3-Jun-09 5:19  In the Crystal Report Designer look in the Data Expert and you will be presented with 100's of ways to connect to data, choose stored procedure. AFAIK, the viewer control has nothing whatsoever to do with creating the report, just rendering it to the screen. Need custom software developed?

So, if i would be able to provide the stored procedure by Data Expert (even this also i have to serach more) then how i will pass these query string parameters to the report please. Regards Girish Sharma Re: Oracle Data reader with Crystal Report Viewer Ennis Ray Lynch, Jr.3-Jun-09 5:26 Ennis Ray Lynch, Jr. 3-Jun-09 5:26  When you bind to the stored procedure using the data expert, Crystal will create parameters for the report. You can then use C# code to map the query string parameters. Crystal Parameters with C#[^] Need custom software developed? I do C# development and consulting all over the United States.

Right now i am at my home and the work is going on office's pc, so i will try to implement your suggestions, and if need any further query, will post the same here or will mail to you by my mail id i.e. gksharma0481@yahoo.co.in. Best Regards Girish Sharma Re: Oracle Data reader with Crystal Report Viewer Girish4814-Jun-09 0:25 Girish481 4-Jun-09 0:25  As you suggested, i have created new report by data expert using stored procedure, which is taking 2 varchar2 arguments. I have placed following code in secm.aspx.vb file: CrystalReportViewer1.ParameterFieldInfo.Clear() Dim parameter As ParameterFields = CrystalReportViewer1.ParameterFieldInfo Dim strtrol As ParameterField = New ParameterField() Dim endroll As ParameterField = New ParameterField() strtrol.Name = "par_strtrol" endroll.Name = "par_endroll" Dim xxx As ParameterDiscreteValue = New ParameterDiscreteValue() xxx.Value = Request.QueryString("startrol") strtrol.CurrentValues.Add(xxx) parameter.Add(strtrol) xxx.Value = Request.QueryString("endrol") endroll.CurrentValues.Add(xxx) parameter.Add(endroll) CrystalReportViewer1.ParameterFieldInfo = parameter CrystalReportViewer1.ReportSource = Server.MapPath("secm1998.rpt") But when it is showing error "The parameter is incorrect." and a blank crystal report viewer control comes on the screen. How to resolve it or any other way by which i can pass query string parameter to crystal report for crystal report viewer; please guide me. Thanks & Best Regards Girish Sharma Web App Builder developer63-Jun-09 3:53 developer6 3-Jun-09 3:53  I've got a requirement to build a fairly simple data entry & retrieval application with a small amount of workflow. Is anybody aware of a tool that would, for example, take a description of the business model and spit out an ASP.NET application? I guess what I've got in mind is something like MS Access for building web apps - hope that makes sense. Another way of phrasing the question would be: How can somebody that is unfamiliar with building web apps get up & running in the shortest possible amount of time? Any pointers in the right direction would be greatly appreciated. Ciao.

Re: Web App Builder RichardGrimmer3-Jun-09 4:55 RichardGrimmer 3-Jun-09 4:55  Ironspeed[^] immediately springs to mind - not sure what its capabilities are nowadays though. C# has already designed away most of the tedium of C++. Re: Web App Builder developer63-Jun-09 5:07 developer6 3-Jun-09 5:07  That looks to be pretty much the kind of thing I'm after. If yourself or anyone else could comment on how easy it is to get up the learning curve, implement user access rights, "record" locking, etc that would also be useful. I will research this as best I can from the link you provided, however, it is always useful to hear from people that have had real-life experience of any given tool. Many thanks. Ciao. Re: Web App Builder RichardGrimmer5-Jun-09 1:03 RichardGrimmer 5-Jun-09 1:03  I didn't use it myself above and beyond installing and having a quick play - it wasn't what I needed for the project. That's not to say it was no good, just didn't fit what I wanted. Just one caveat - downloading the demo obviously put me onto some sort of marketing list - I got bombarded with phone calls and emails from them afterwards - not the usual spam per-se, but more "how can we help you decide to buy" type things - still irritating though.

Is it possible with an http handler or something or in my ashx file to determine what type of content the users request is looking for? Like an so can I pick that up on server side? I need to determine if the image they are requesting(from my ashx page) is in an img tag on their site or if they are loading the direct link like xxxxx.jpg. Thanks Re: Determine the type of request?

Matt Cavanagh3-Jun-09 6:50 Matt Cavanagh 3-Jun-09 6:50  The problem with that is that the referer url doesnt tell the difference between if they have clicked a link and ended up at my site or if another page is loading an image from it. How would I bring SSL into it? Really? Ennis Ray Lynch, Jr.3-Jun-09 8:05 Ennis Ray Lynch, Jr. 3-Jun-09 8:05  http://en.wikipedia.org/wiki/HTTP_referrer[^] Suggests that the referrer would be empty if the user typed it in, populated with a remote site if some one linked to you, and contain your site if you directed it. I believe SSL keeps a browser from spoofing your own URL in the referrer because you can check for a valid secure connection. Need custom software developed?

You need to underatnd the difference between the assesmbly reference and the web reference. When you add a web reference, the visual studio creates a proxy to the web service to help your application communicate.

Extending DotNetNuke Blog module -- Problem in configuring the source code Rocky#3-Jun-09 3:37 Rocky# 3-Jun-09 3:37  Hi everyone, I'm looking to change the FCKEditor inside the blog module and I'm replacing it with a third party control. I need to access some of its properties in there, preferably in the Page_Load event as well. I have Blog_03.05.01_Source.zip (CodePlex[^])package with me and inside that there was another zip file with the name DNN_Blog_Resources.zip which seems to have the actual source code. Now comes the problem: This is a VS 2003 solution which is not getting converted to VS 2008 that I'm using at the moment. So far I want to make changes in the EditBlog.aspx and EditBlog.aspx.vb. and BlogModuleBase. It's the first time I'm customizing any DNN module. So far I've understood from the discussion that I need to build it after modifications and plug in the appropriate dll's in the DNN website's Bin folder. But the question is, can I customize the blog module in VS 2008? if yes then how? or do I have to go back to VS 2003 somehow and make a build in there? and... how do we configure the dnn blog project?
