1. Hello

the company's sales adopt the regional agency system, and the price is set by the local agents or dealers according to the local sales situation and economic level. The company does not set the price uniformly. In addition, e to the rapid upgrading of electronic procts, the price will fluctuate in different periods of time. This business will decide according to the actual situation of the local, which will bring you inconvenience. Please understand
please feel free to contact us if you have any questions. Thank you very much for your support to vivo. I wish you a happy life!

2. 55si2mn spring steel silicon and manganese improve the elastic strength and yield ratio, improve the hardenability, anti tempering stability and anti relaxation stability, overheat sensitivity is also small, but decarburization tendency is larger, especially when the silicon and carbon content is high, carbon is easy to graphitize, making the steel brittle. 55si2mn spring steel can be used as damping leaf spring, coil spring and cylinder safety valve spring for automobiles, tractors and vehicles, and can also be used as heat resistant spring below 250 ℃

3. There is no difference between MAC and PC Internet. Except for the driver
Apple notebook, almost all wireless routers are compatible

feel very comfortable. Buy a wireless router

several wireless routers such as cercomm, tp link, Netgear and Airport express, you can use Apple's system normally.

If not, it means that you lack this control in your new computer and need to it to the original computer. Click the control and locate below to get the file name of the control.

5. Please press the power button for more than 10 seconds to force the restart. If it still doesn't work, it is recommended to try Shuangqing. You can press and hold the volume up key + power on key at the same time, and wait for the mobile phone to appear vivo. Release the power on key, and continue to press and hold the volume up key until the robot interface appears. Select wire data / factory reset, and then press the power on key, and wait for the interface to jump, Then select reboot system now to restart the phone. This operation will lose all data on the mobile phone, including installed applications, phonebook, SMS, etc. If it doesn't work, please take your mobile phone to our after-sales service center. The address and telephone number of the after-sales service center can be accessed to the home page of vivo official website service network inquiry.

7. There is no need to use the integrated water-cooled radiator at all. The effect of a good air-cooled radiator is much better than that of an ordinary integrated 240&# 65532; Limin Fengying ta140 radiator, 5 heat pipes, 339 yuan, and then buy Xinyue 7921 silicone grease, 19 yuan, so you can play rainbow 6 with the highest image quality special effects,

8. IFIX database into SQL or other databases
(1) iFIX real-time data into SQL
establish SQT SQD in iFIX database
SQT for basic configuration (equivalent to the scheme configuration of triggering data collection)
SQD contains the list of data to be imported
look at the top post, Historical report
(2) iFIX real-time data in and out or into other databases
you can call iFIX vdba.dll programmatically
for details, please refer to iFIX development manual

through this method, you can access iFIX real-time database in real time

you can directly access iFIX real-time data in delph

the first method Methods belong to indirect methods, but are easy to

the second method belongs to direct method, which needs a lot of resources to support.
