Problem deploying in a web page a Windows User Control containing a Chart FX for .NET 6.2 Chart object

[User (Legacy)]

Hi,

I have created a windows user control containing, among other controls, a 

SoftwareFX.ChartFX.Chart control. The goal is to deploy my user control in a 

web page to let the user interact, via JavaScript, with the chart contained 

in it.

I configured my strong key signed assembly with the 

AllowPartiallyTrustedCallers attribute. And on the constructor of the user 

control I configured the PermissionSet.

Then on the client side I created, under .Net Configuration, the Runtime 

Security Policy granting my assembly FullTrust permissions by using its 

strong name's public key. I did the same thing with the assemblies of 

SoftwareFX.

I also opened the manifest of my assembly and checked that the 

WindowsControlLibrary1.dll.licenses resource that references my Chart FX for 

.NET 6.2 license was indeed embedded inside the assembly.

Nevertheless I cannot load the control on my page and I keep finding this 

error in the Temporary Internet Files of Internet Explorer 6:

It seems like I have problems with my type of deployment and my Chart FX 

license. Could anybody give me any clues?

Thanks

Thanks for your quick answer. I had already read the articles you mention. 

As for article Q6101001, it seemed to be the solution, but after checking my 

project I corroborated that Visual Studio .Net 2003 had already done the job 

for me and the licenses.licx file had been added to my project and it was 

being included in my assembly as an embedded resource. Anyway, to make sure 

that it was all being done the right way, I also followed the manual 

procedure described in article Q6101010, but that didn't work either.

I would like to know if there is a workaround to this problem. Be it a 

program modification, or an ad hoc configuration of the client computer or 

maybe some sort of license modification as it seems to be alluded in article 

Q6101008 where it says "Please contact Software FX if your specific 

situation requires a different licensing scheme".

Thanks again.

The license must be in the EXE, not in the DLL, in this case the EXE is 

Internet Explorer so you can not put it there.

The license WILL NOT be read from your DLL as this would allow you to wrap 

the control and by-pass the license.

Please contact Software FX for licensing options.
