GDPicture Start slow

[kyosukec]

Dear Sir,

In one window 2008 server, after I install the GDPicture and start the sample application "Document Viewer.exe", it takes around 1 min in order that the form show up.

Attached please find the screenshot, it is find that the process is started in the task manager,
it CPU cost is zero during the time it waiting, and then it finally pop up. It seems that it wait for something to timeout

In fact not only that application, all application reference to GDPicture also takes 1 min to start up. Is there any hints what would affect this? Many thanks

Hello,

The problem is probably caused by the authenticode verification process.

Some information from http://msdn.microsoft.com/en-us/library/cc656914.aspx

Authenticode verification adds to the startup time. Authenticode-signed assemblies have to be verified with the certification authority (CA). This verification can be time consuming, because it can require connecting to the network several times to download current certificate revocation lists. It also makes sure that there is a full chain of valid certificates on the path to a trusted root. This can translate to several seconds of delay while the assembly is being loaded.

Consider installing the CA certificate on the client computer, or avoid using Authenticode when it is possible. If you know that your application does not need the publisher evidence, you do not have to pay the cost of signature verification.

Starting in .NET Framework 3.5, there is a configuration option that allows the Authenticode verification to be bypassed. To do this, add the following setting to the app.exe.config file:

Code: Select all

<configuration>
    <runtime>
        <generatePublisherEvidence enabled="false"/> 
    </runtime>
</configuration>

Kind regards,
