How to run the demo for testing

A: The software development kit(SDK) is available in two forms:

A) Provided as .exe application suffix, in this situation you need to double-click the installation and pay attention to the installation directory. After the installation is complete, you can find the demo in the installation directory under the path of C: \\...

B) Provided as compressed package, you can open the demo test after decompression.

*The B/S architecture development kit needs to run the signature service program in the directory first, then open the Web to run normally; the C/S architecture can directly run the project examples or Exe demonstration programs. Both B/S and C/S architectures need to connect the signature pad/display before testing.

What browsers does the SDK support?

A: Most common browsers on the market are supported. Google Chrome uses Websocket for communication, and IE uses OCX plug-ins or HTTP for communication.

PS: IE11 and above browsers support websocket communication

What valid information should I provide before obtaining the Software Development Kit (SDK)?

A: A) The architecture of the business system (B/S or C/S).

B) Information of the computer operation system (Windows 7 / Windows 10 / Linux, etc.). If it is a Linux system, additional CPU architecture or model name is needed.

How do I get the Software Development Kit (SDK)?

A: Please go to our Github to download: GitHub - Hyan-hub/SDK, or contact our technical support via email signature.software@ugee.com to obtain.

The pen grabs mouse cursor when opening demo test

A: You don't need to install any other drivers in SDK for secondary development. Please check whether your computer has installed [pentablet] driver. If so, please uninstall it.

Web_NSV occasionally returns a blank image after the callback function. 

A:The reason is that the plug-in service is initialized and connected multiple times. It is necessary to ensure that there is only one connection when signing. If there are multiple-page signature requirements, please destroy the connection in time after callback is successful. 

* This issue applies to all B/S architectures.

(Individual cases) Interface function requests Timeout under Web_NSV?

A:To ensure the normal and stable operation of the plug-in service, at most two interface functions are called simultaneously in one event response request. If more interfaces need to be called, a delayed response is required. 

* This issue applies to all B/S architectures.

Web_NSV cannot connect to Websocket

A:You need to check whether the service plug-in is running normally and whether there is any running port conflict.

Handwriting area can not correspond to the demo signature box under Web_NSV or/and ActiveX

A:You need to set the mapping area according to the API document.

Example: setDisplayMapMode(mode, callback);

DisplayMapMode(); etc.

The computer reminds “No device is connected” when opening demo with ActiveX.

A: The OCX control needs to be registered when it is installed for the first time. Open the compressed file path \\Plugins, run RegOCX.bat as administrator, register and then reopen it.
