Error registering Syncfusion.GeckoWrapper.dll

[Joshua]

Hi,

I've been trying to test HTML to PDF conversion using the Gecko engine via the GeckoHtmlRendererControl class, but when I try to register the Syncfusion.GeckoWrapper DLL as described in the online documentation I get the error:

'The application has failed to start because its side-by-side configuration is incorrect.'

When I check the event log I find the error:

'Dependent Assembly Microsoft.VC90.DebugCRT,processorArchitecture="x86",publicKeyToken="1fc8b3b9a1e18e3b",type="win32",version="9.0.21022.8" could not be found'

As far as I can tell the DLL it is looking for is installed as part of Visual Studio 2008, but shouldn't be redistributed as it is for debug only.

Is this correct? Am I missing a step or is there somewhere I can get this DLL?

Thanks

Hi Joshua,

Thank you for your interest in Syncfusion products.

GeckoWrapper.dll requires ATL90.dll & msvcr90d.dll to be present in the machine. You can get those assemblies by installing VC++ 2008 (SP1) Express edition in the machine.

Here are the steps to follow:

1. Install Visual C++ 2008 Express Edition with SP1 from the following link:

http://www.microsoft.com/en-in/download/details.aspx?id=14597

2. Copy the XulRunner-2.0.sdk (shipped with install – {Installed Drive}:\Program Files\Syncfusion\Essential Studio\{version number}\XulRunner-2.0.sdk\bin\) to the server.

3. Register the Syncfusion.GeckoWrapper.dll using the following command in command prompt:

regsvr32 Syncfusion.GeckoWrapper.dll

Please try this and let me know if you have any questions.

Thanks for that, I've been able to register the DLL now and make some progress.

Unfortunately I'm still having problems - when I call the Convert method on HtmlConverter, the HtmlToPdfResult instance I get back has no RenderedImage set, and so when I try to render it I get an 'Image cannot be null' PdfException.

I've attached the code I'm using for the conversion, but I can't see anything in it that would cause the conversion to fail to produce an image.

Please let me know if you can recreate the problem or if there is anything I can check or try.

Thanks

Hi Joshua,

Thank you for the details.

Could you please make use of the following code snippet and send us the HTML if it does not work for you?

Dim document As New PdfDocument

Using renderer As New GeckoHtmlRendererControl()

      Using converter As New HtmlConverter(renderer)

            Using result As HtmlToPdfResult = converter.Convert(sHtmlPath, ImageType.Metafile, CInt(Fix(width)), CInt(Fix(height)), dimension)

                result.Render(document)

            End Using

      End Using

End Using

That did the job, the conversion seems to be working fine now.

Thanks for your help.

Hello,

I had the same problem with with Syncfusion 12.1.0.43.  Will Syncfusion have an upgrade where the Visual C++ 2008 won't need to be installed or is this just a requirements to use the GeckoHtmlRendererControl class?

Thanks,

Jeremy

The link in number one below no longer works, can you provide an updated link please.

In step 2 below you say "Copy the XulRunner-2.0.sdk (shipped with install – {Installed Drive}:\Program Files\Syncfusion\Essential Studio\{version number}\XulRunner-2.0.sdk\bin\) to the server."  

do you mean copy the bin folder of the source to the bin folder on the destination?  If so I really don't want to copy ALL the files as there are so many, I just want to copy the necessary files.  Please provide the list.

In step 3 regsvr32 Syncfusion.GeckoWrapper.dll

returns an error.  Any ideas?

1. Install Visual C++ 2008 Express Edition with SP1 from the following link:

http://www.microsoft.com/en-in/download/details.aspx?id=14597

2. Copy the XulRunner-2.0.sdk (shipped with install – {Installed Drive}:\Program Files\Syncfusion\Essential Studio\{version number}\XulRunner-2.0.sdk\bin\) to the server.

3. Register the Syncfusion.GeckoWrapper.dll using the following command in command prompt:

regsvr32 Syncfusion.GeckoWrapper.dll

Hi Jeremy,

Thank you for using Syncfusion Products.

 

GeckoWrapper.dll is built in debug mode and it requires ATL90.dll & msvcr90d.dll to be present in the machine. Being debug assemblies, these cannot be shipped using xcopy method of deployment. Hence it is required to install VC++ 2008 (SP1) Express edition and VC++ 2010 express edition, in the server.

 

Thanks,

Hi Eric,

Thank you for your update.

 

Please find the modified link in the below location.

http://go.microsoft.com/?linkid=7729279

 

For registering the Gecko Wrapper, we have to copy the XulRunner once in the server and then we have run the XulRunner for registering. The error in Step-3 may due to the missing of assemblies please provide us the error message so that we can provide you the proper solution.

 

Thanks,
