Error: Error calling method on NPObject!

[donesc...@gmail.com]

Hi all,

 

Windows 7, FF 21.0.

I want to use the CAPICOM ActiveX (installed upfront on the PC) with Mozilla. This control is used for digital signatures etc.

I wrote some code using the example from the Wiki and I also enabled logging.

I create the objects HTML, giving the first one some size, the other objects are hidden.

I get this error: Error: Error calling method on NPObject!

 

When I load the Webpage I get this log:

 

AxHost.NPP_New: debug level set to 5
AxHost.verifyClsID: verified successfully
AxHost.setClsID: CLSID {94AFFFCC-6C05-4814-B123-A941105AA77F} set
AxHost.verifyClsID: verified successfully
AxHost.setClsIDFromProgID: PROGID CAPICOM.SignedData resolved and set

AxHost.verifyClsID: verified successfully
AxHost.setClsIDFromProgID: PROGID CAPICOM.Signer resolved and set
AxHost.CreateControl: control created successfully
AxHost.UpdateRect: failed to attach control

 

Then I click the SIGN button to digitally sign some text and get Error: Error calling method on NPObject!.

I have attached both my code files

How can I fix this problem?

I saw this reply: https://groups.google.com/forum/#!searchin/ff-activex-host/AxHost.UpdateRect$3A$20failed$20to$20attach$20control|sort:relevance/ff-activex-host/-vkl4MWcNAk/6QRt-QuRWsIJ. I am wondering if the same solution will work for me, my scenario is not like theirs.

 

Thanks,
