Crystal Reports images not visible in web viewer

Question

I have some Crystal Reports (V10) in an application (.NET 1.1) I inherited that is deployed in four \"identical\" environments. In three of the environments, they are workin

Answer 1

I could resolve this issue in dev enviroment adding next keys (handlers) to web.config:

<system.webServer>
  <handlers>
    <add name="CrystalImageHandler.aspx_GET" verb="GET" path="CrystalImageHandler.aspx" type="CrystalDecisions.Web.CrystalImageHandler, CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" preCondition="integratedMode"/>
  </handlers>
</system.webServer>


<system.web>
  <httpHandlers>
    <add verb="GET" path="CrystalImageHandler.aspx" type="CrystalDecisions.Web.CrystalImageHandler, CrystalDecisions.Web, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/>
  </httpHandlers>
</system.web>

Answer 2

I recently experienced this very issue: although my resolution was a little different:

• I tried setting the handler in the web.config but that didn't fix it.
• I tried setting scripts & executables in IIS but that didn't fix it.

Once I went into the C:\Program Files\Common Files\Crystal Decisions\2.5\crystalreportviewers10 folder and turned off custom errors I could see the error was coming from an access denied issue on C:\Windows\Temp\

The solution was then to not and handlers or alter IIS to run scripts and executables, it was to allow the Network Service to read permission on C:\Windows\Temp\

EDIT: Think I've found another solution which doesn't require permission changes... just set a virtual directory for aspnet_client; the level at which you select this will very much depend on your IIS layout.

Answer 3

Add the aspnet_client folder in the source folder of the site. Example:

C:\inetpub\wwwroot\myapplication\aspnet_client\system_web\4_0_30319\CrystalReportWebFormViewer4

Answer 4

There needs to be an IIS virtual directory called something like "CrystalReportViewers115". I think that the exact name changes between versions. This needs to be visible to your ASP.NET user. Start looking at the environments that work and see if they have this virtual directory installed, and compare it to the one on the failing environment. As another check, you should be able to enter in the URL for the images into a browser and see them. To find out the URL, right click on the picture and select "Properties". For example:
http://localhost/crystalreportviewers/images/toolbar/export.gif
You should see the picture when you browse directly to the URL.
