Display Dynamic QR Code In Crystal Report In .net Page C# Code-behind

Mar 14, 2011

I'm using CRv9 and want to make use of Google Charts API for generating QR code on fly (in asp .net) and display it in the Crystal Report in a PDF format.I have spent the whole day looking for solution with no luck. The way we output the report is we use .rpt file, feed it with data and use Response.OutputStream to feed to browser. No CrystalReportViewer control hence CSS solution is not an option.

Now, I got as far as added an OLE Object from file with Link, which I would be overwriting every time the new QR code is generated. I apreciate that CR requires it to be a bitmap, so I was planning to download and convert the google's generated PNG file to BMP, that's not an issue. The problem is that Image in the report does not update after I replace the file. Meaning, it displays the original image, which was added as an OLE Object.

If I open this report in CR designer, the image gets refresh/updated and I'd have to save changes to the report to see this new image next time I generate a PDF file.The question is really how to achieve a dynamic image in Crystal Reports 9? Remember, Picture object did not have a Graphic Location property until vXI, so I cannot use that.

Manipulations with DataSets is not an option either as we're not giving report a datasource, instead we just map the fields with FormulaFieldDefinitions.

sample qr code url: https://chart.googleapis.com/chart?chs=150x150&cht=qr&chl=Hello%20world&choe=UTF-8

Mar 11, 2011

I create an ASP.NET Crystal Report Web application using VS.NET 2010. In ASP.NET page, I stored two values in Session state and need to pass them as input parameters to Oracle stored procedure.

Detail code:

1. ASP.NET page store the values in the Session:

Sesion.Item("CourseNumber")
Sesion.Item("StudentNumber")

2. I like to pass above values to the store procedure with IN parameters named P_CourseNo and P_StudentNo to print out the Crytal Report with Store Procedure as data source.

2) Is there a way that I can use one Report viewer and 25 Crystal reports display according to the condition?

Web Forms :: How To Generate HTML Code By Commands From The Code Behind Page

Dec 30, 2010

how to generate HTML code from the code behind?

I would like to build a form that generate an html code inside a for loop.

I will let the user enter the photo name and No. of photos

Then I will generate an HTML code like this:

<a href="http://www.mzinj.org/images/gallery/Photo%20(1).jpg" target="_blank"> <img src="http://www.mzinj.org/images/gallery/Photo%20(1).jpg" alt="" width="345" height="247" /> </a> <br /> <a href="http://www.mzinj.org/images/gallery/Photo%20(2).jpg" target="_blank">
<img src="http://www.mzinj.org/images/gallery/Photo%20(2).jpg" alt="" width="345" height="247" /> </a> <br /> <a href="http://www.mzinj.org/images/gallery/Photo%20(3).jpg" target="_blank"> <img src="http://www.mzinj.org/images/gallery/Photo%20(3).jpg" alt=""
width="345" height="247" /> </a> <br />

depending on the No. of the photos the code will be duplicated in the loop

Then I will display the result of the loop in label or in a textarea to let the user copy it any where

The problem is that while compiling my code it considers the HTML code as a part of the behind file and gives errors on the single quote, the double quote and on the parentheses
