CR 2008 SP 3, VS 2008, ASP.Net, javascript errors

[Former Member]

Hello,

I've been working for the last couple of weeks trying to upgrade from CR 10 to CR 2008 SP 3. I have a web application that I developed in VS 2008.

I installed CR 2008. Then I installed SP 1, then I installed SP 3 trying to eliminate the 'bobj' is undefined error. I'm developing on my local machine and using localhost. IIS is not installed on the machine I am developing with. I could run Crystal Reports before the upgrade, but the 'export' and 'print' buttons would not work. I have one module that has a crystalreportviewer, when I select a report for viewing I get the error.

Can someone point me in the right direction? I'm at my wits end with this and pressure is beginning to mount.

Thanks for any help

Thanks for your response.

I have searched, found the threads, tried all of the ones that I could understand and still have the problems. Haven't found any solution that resolves my issues.

It would be helpful if you could mention OS (32 bit or 64) used?

IIS version?

Do you see "crystalreportviewers12" folder in C:\Windoews\Microsoft\Framework\v3.0\ASP.NETCleintFiles or in

C:\Inetpub\wwwroot\aspnet_cleint\ ?

You can check all the framework versions on your system(C:\Windoews\Microsoft\Framework\) for "crystalreportviewers12" folder.

Thanks

XP Pro Version 2002 SP 3

I don't know the bit, or where to find it.

Don't have IIS.

C:\Windoews\Microsoft\Framework\v3.0\ does not contain the crystalreportviewer12 folder.

C:\Inetpub\wwwroot\aspnet_cleint\ does not exist on my machine.

The folder is in here:

c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\ASP.NETClientFiles\crystalreportviewers12

along with folder:

c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\ASP.NETClientFiles\CrystalReportWebFormViewer4

I have moved those 2 folders all over the place trying to get it to work. My site is here:

C:\dev\mysite

I test it using localhost:

[saurabh_pathak · Accepted solution]

Try instaling IIS then proceed further.

I would suggest you do it on a clean machine where IIS exist/installed and try re-installing everything.

(Missing) IIS is the most likely reason for various errors you have with your application.

Thanks,

Saurabh

Saurabh's suggestion regarding the ASP.NETClientFiles\crystalreportviewers12 is usually spot on in cases like this. Is your application configured for the 1.1 framework or something like that?

When the Crystal Report Web Form View is rendered in the casini personal web server, we load all the viewer resource files from C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\ASP.NETClientFiles\crystalreportviewers12. That includes images, js, and css files. In your case, is it only a javascript file error? Or are you not seeing any toolbar or images too?

If it is just the JavaScript problem then you are likely missing the \js folder, or the .js files.

I suggest you use Process Monitor and see what your application is looking for. When you get a result log in proc mon, filter your results on the path that includes "crystalreportviewers12". Then look to see what is failing. It will give you a better idea of what is missing.

If your crystalreportviewers12 is broken, you can download another copy using the link below. This is from one of my test systems. Note: This will only be available for 21 days.

Thanks for all the response. I left work Friday afternoon and tried to forget about my CR problems.

I will try to answer as many questions as I can.

Framework 2.0

When I try to run the reports module, I never see the report viewer. I see the param prompt page, but that's as far as I get. One of the params is the FY(fiscalYear), when I start typing 2011, I get 2-3 java errors for every digit I type then I Click 'OK' and the prompt page just refreshes.

The 'js' folder is inside of the crystalreportviewers12 folder with .js files inside.

Where I work, I cannot install IIS or Process Monitor. They have been using CR with .NET for years. We're just wanting to upgrade.

I am running from VS 2008 IDE. In Solution explorer my site looks like c:\dev\mysite, In browser it looks like:

http://localhost:2567/mysite.

If I type inetmgr in command prompt, I get "Windows cannot find 'inetmgr'".

Process Monitor isn't an application you install. It is an executable that you can run without an install (no reg keys or large footprint). If you aren't able to use a tool like this you are going to have a very tough go at resolving this issue.

I'd suggest completely removing Crystal Reports and re-installing if you aren't able to troubleshoot this. Below is a link to the full installer for Crystal Reports 2008 SP3.

One thing I did notice in your web.config is your image handler is wrong. You have two versions of CrystalImageHandler in your <httpHandlers> section. You need to delete the 10.5.3700 element.

Wrong

I replaced my crystalreportviewers12 folder with the one from the link above. Still have the same error. Below is the line where the first error pops after selecting my report:

pe.init('../aspnetclient/system_web/2_0_50727/crystalreportviewers12/prompting',200);

error says:

Microsoft JScript runtime error:'_pe' is undefined

Given that, can you tell me where the aspnet_client folder should be?my site is at c:\dev\+mysite+

I can't use the Process Monitor, not an administrator. I can't help but think that this is a simple problem that I/we haven't found yet. Those are the ones that drive you crazy.

After I upgraded to CR 2008, is there something that I need to do in VS 2008 to tie those two together.

[former_member208657 · Accepted solution]

As I mentioned in a prevoius post, the correct location is C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\ASP.NETClientFiles\crystalreportviewers12. This is the location we use when you use the personal web server in Visual Studio 2008.

I strongly suggest you find a way around your admin credentials issue so you can use Proc Mon. Otherwise you will have a very hard time figuring out what directory is actually giving you problems.

Remove and re-install of Crystal Reports 2008 is still an option.

[Former Member · Accepted solution]

I removed my CR 2008 and downloaded the SP 3 full build from the link provided up above. When I try to open the .zip I get a warning that says 'Cannot open file: it does not appear to be a valid archive.'

Do you have another link I could use?

[former_member208657 · Accepted solution]

Your download likely was corrupted somehow. I just downloaded the zip file to a test machine and it unpacked successfully.

Can you try downloading again?

[Former Member · Accepted solution]

Ok, I've downloaded the file 3 times now and everytime I get the error.

very frustrated.

[Former Member · Accepted solution]

I'm having trouble getting to the ftp site. I had my Network Admin try to set up the transfer, he's using FileZilla. He can get connected to the sever, but he can't see the directory. He keeps getting this error:

Error: GnuTLS error -53: Error in the push function.

Error: Connection timed out

Error: Failed to retrieve directory listing

We've changed settings back and forth, but still can't see the directory.

Please check and advise.

Thanks.

I've uploaded the file for you to one of our other file sharing servers. You can download the file using the link below. It may take 30 to 60 minutes to become available.

I got the file from the link you provided. Ran the .exe, went through the set up, opened my site in VS 2008 and ran it; 'Debug->Start Debuggin', from the IDE.

I still get the same error.

Microsoft JScript error: '_pe' is undefined.

When I click 'continue' or 'ignore' it just goes to another JScript error.

I think the '_pe' error is relative to the parameter prompt. When I select a report that doesn't have to prompt for parameters, I get the 'bobj' is undefined error.

Did I miss something in the setup?

[Former Member · Accepted solution]

I have the same error if I run the application from Visual Studio in the Development Server. If I change the project properties so the local IIS Web server is used, then the problem disappears...

Hi rlozbim,

Are you running the application from VS2008 IDE? if not, are you typing a url to your app in the browser?

Please describe.

If you are running the application from VS2008 IDE, with the website located on the file system then you really do not need to install IIS. Anyway, no harm in installing it. In solution explorer, how does the website name look like:
localhost\dev\mysite OR c:\dev\mysite\

What happens if you run the inetmgr command in the run box? Please post the contents of the web.config file of your application.

cheers!

[saurabh_pathak]

I may be wrong, while running .NET application (with no CR) you may not require IIS to be installed on the dev machine.

When CR is used in .NET application then we require IIS because crystalreportsviewer12 is also installed in one of the subfolders of aspnet_client.

Thanks,

Saurabh
