My asp.net app used Crystal report to display as pdf file.
If I open the report in my pc (newest version, Adobe reader 9), it is ok but once I open app in web server (Adobe reader 8), it display a blank screen.
I have got a desktop application which was build in vs2005, now i am doing conversion of it to web application (vs2008). i have got around 40 crystal reports in it (desktop application).
tell me can i use them (rpt files) directly in web application or i will have to create all new reports?
How to determine whether the Adobe Acrobat Reader has been installed or not on the client PC?
View 7 RepliesOur ASP.NET application allows the users to review any number of PDF forms. A simple listbox holds filenames and the forms are displayed inside a standard iFrame. The setup is simple and effective: when the user clicks on a filename, that filename is loaded into the iFrame, and shown to the user.
Users are allowed to digitally sign the forms. For appearance purposes, a bitmap of the user' signature is generated and placed in the appropriate location of the PDF form.
The bitmap file format is GIF, and the background is transparent.
We use iTextSharp for form-filling, and we also use iTextSharp to place the bitmap on the forms. Nothing special.
We can readily verify that the signature bitmap is correctly placed on the form, and that the bitmap itself is definitely transparent.
Problem 1:
After placing the bitmap of the user' signature on the form, the form is reloaded and displayed to the user (for verification) and, in most cases, the forms do not display the bitmap. Opening the PDF reveal that the bitmap has been placed and is definitely visible in Adobe Reader (9 and 10 - these are the versions available for testing).
Experimentation and quite a bit of research seems to suggest that the problem lies in caching. One of the possible solution/suggestion is to append a time-stamp or a GUID to the URL, when loading the form after applying the bitmap. In theory, this should prevent Adobe Reader from using a cached copy of the PDF form.
We have tried appending a time-stamp and/or a GUID, without any success: the forms still display without the bitmap. At the risk of repeating myself: the PDF form is correctly signed, and the bitmap is correctly placed. It is just not visible.
This problem seems common to users running the application on intranet web servers (IIS 7). The one application instance running on public web server (IIS 7) does not seem affected by this problem.
Problem 2:
As mentioned, the GIF file generated by our application has a transparent background. In almost all cases, Adobe Reader (9 and 10) seems to understand and respect the transparency of the bitmap.
In one very peculiar case (when the application is running on a Windows 7 64 bit machine with IIS 7), when the bitmap is placed on the form, it becomes opaque (complete loss of transparency).
Again, the problem seems related to Adobe Reader, because the bitmap being applied positively sports a transparent background.
I am using the code from: [URL] ....
Everything seems to work, expect when I try to open the PDF file Adobe Reader says:
"Adobe reader could not open 'filename.pdf' because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded)."
I tried opening it in Adobe Photoshop and was not able to there either.
In a VB.Net project I use the Adobe PDF Reader (AxAcriPDFLib) control to display a preview of a selected PDF document whereafter the user can double-click upon the selected listbox item to enjoy a full screen view of the relevant PDF document. see the attached sample in this regard. Is there any way to emulate this in ASP.Net?

Runtime Error Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off". Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL. ----------------------------------- This error will be display when I am try to show the Crystal Report. Can anybody tell me what Property I have to ser in Windows Server 2008 R2 or in IIS7???
View 1 Repliesa myth has been passed to me by a senior who told me to 'always' design a crystal report using Add command and not through the table view (like selecting tables and linking them manually).I have been having a hard time writing the queries for master detail reports and making sub report links manually. It gets pretty confusing sometimes.I find it easy to design reports by just selecting two tables and dragging and dropping the link in crystal report designer.
