【Answers to general questions】  

1.1 What is the default user ID and password?

The default user ID and password is SUPERVISOR and PASSWORD respectively.

1.2 [Wrong Password] showed when I input [Supervisor] for user ID and [Password] for password?

It happened when the setting of Language Driver of Database Engine is wrong. Generally, it is usually under English version MS Windows or set [Country] to be [non Chinese countries/area] under Chinese version MS Windows.

To fix the problem, please do the followings:

1. To delete the directory of database, e.g. C:\GTC\GBSe\DATA.
2. Run BDE Administrator in Control panel.
3. Select Configuration\Driver\Native\PARADOX and find Langdriver on the right hand side.
4. Change the setting of Langdriver to: 'ascii' ANSI for English; Paradox Taiwan 950 for traditional Chinese; Paradox China 936 for simplified Chinese.
5. Select System\INIT and change the setting of Langdriver as step (4).
6. Close BDE Administrator and save the change.
7. Run the Application again.

1.3 Why there is the message of [System Error: Index out of Date]?

It happened when there is a difference between index file and master file of database. Generally, it caused by the computer shut down inappropriately.

To fix the problem, please use Database Tools under Utilities to correct the database.

If this problem occurs many times, please check:
a) Whether the computer shut down inappropriately for many timesIf yes, please check the installation of hardware and MS Windows.
b) If MS Windows 95 is being used, the version of VREDIR.VXD should be version 4.00.1116, 56,773 bytes, 11 Sep 1997, 11:16 or above and the version of VNETSUP.VXD should be version 4.00.1112, 17,595 bytes, 30th May 1997, 11:12 or above.
New version can be downloaded from support.Microsoft.com/download/support/mslfiles/VREDRUPD.EXE and refer to Microsoft's Knowledge Base articles Q14836 and Q174371.

1.4 Why there are non readable Chinese characters in GTC Application's interface?

Firstly, please confirm the language of GTC Application's interface matching with the language of MS Windows. For example, if the language of MS Windows is traditional Chinese, the language of GTC Application's interface should also be traditional Chinese. To change the language of GTC Application's interface, you can press <Ctrl-E> for English, <Ctrl-B> for traditional Chinese, <Ctrl-S> for simplified Chinese.

If the language of GTC Application's interface is same as the language of MS Windows, there are still non readable characters. Please refer to the followings:

a) For MS Windows 2000/XP, choose <Regional Settings> in Control Panel. Please select desired district in Advance page. For example, select [Chinese (Hong Kong)], [Chinese (Macau)], [Chinese (Taiwan)] for traditional Chinese and select [Chinese (PRC)], [Chinese (Singapore)] for simplified Chinese.

b) For MS Windows 98/Me, execute regedit.exe. Please check [HKEY_LOCAL_ MACHINE Associated CharSet] and change the content of [SYMBOL(02)] to [no].

There is a risk to execute regedit.exe, please refer to the following Warning from Microsoft:

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use [Registry Editor] at your own risk.

1.5 Why there are non readable characters when input Chinese?

Generally, it happened when English version MS Windows 95/98/NT with add-on Chinese Interface System. Since our Installation program will automatically set Language Driver of Database Engine matched with language version of MS Windows. That is, English Language Driver will be installed under English version MS Windows.

To fix the problem, please do the followings:

Run BDE Administrator in Control panel. The default location of the file (BDEADMIN.EXE) is: C:\Program Files\Borland\Common Files\BDE. If not found, please contact your System Administrator.

Please select Paradox in Configuration|Driver|Native and change LANGDRIVER in Definition to Paradox Taiwan 950 (BIG 5) or Paradox China 936 (GB). Use mouse to point at right hand side of LANGDRIVER, a downward arrow will appear. Please use mouse to click the arrow for choosing different language driver.

And then, please use mouse to click SYSTEM to choose INIT.

Here, please also change LANGDRIVER to Paradox Taiwan 950 (BIG 5) or Paradox China 936 (GB).

Now, please select [Apply] in Object menu to save system parameter.

Finally, select EXIT to exit.

Note: Please change the Language Driver of Database Engine before the application creates database files. Otherwise, please delete all database files before execute the change. If you have input a lot of data and you want to retain the data, please contact us to change the database format (chargeable service).

1.8 How to enhance the performance of GTC Applications

The speed of CPU and the size of RAM is the most important factors to affect the performance of GTC Application. Normally, the faster speed of CPU, the higher performance of GTC Application. However, data communication is very frequent when GTC Application executed. Therefore, the performance of HDD is more important than the speed of CPU. At least 16MB RAM is required for GTC Application, exclusive the requirement of Operating System.

To improve the method of data communication, please refer to the followings:

1. Anti Virus applications
Anti Virus applications will automatically scan all files when GTC Application reads or writes the data each time. Therefore, the performance of GTC Application will be affected. Please close Anti Virus applications temporarily or exclude the database files (*.db, *.mb, *.px) from scan lists.

2. System Restore
The database files (*.db) of GTC Application are included in System Restore of MS Windows ME/XP. When GTC Application reads or writes the files, MS Windows will make a backup copy firstly. It slows the performance of GTC Application. It can be solved by these two methods:
a) Close System Restore Function
b) Create a separate and independent partition for the database files of GTC Application

3. The speed of Hard Disk
Normally, the faster speed of Hard Disk, the higher performance of GTC Application. Please choose a higher speed of Hard Disk to enhance the performance of GTC Application. Regular maintenance of Hard Disk is definitely important.

4. The speed of network
If the data is placed in server and will be shared in the network, the speed of network is an important factor to the performance of GTC Application. Please seek for advises from your System Administrator or network vendor. There are suggestions:
a) Faster network card: 10/100MB network card for work stations and 100/1000MB network card for server
b) Faster HUB: If possible, please choose switch that is better than HUB.
c) Quality of network card and switch: Data communication relies on the quality of network card and switch. There may be communication errors or even damage on data caused from bad quality of network card and switch.
d) Qualified network accessories: There is an international standard of different network. For example, Ethernet 100MB network requires the network accessories with Cat. 5 or above standard.

【Answers to questions about printing】

3.1 Why only part of the voucher or invoice can be printed on the left side?

It is because your printer driver can't support custom paper size. This happened frequently in MS Windows 2000 since most default drivers for MS Windows 2000 can't support custom paper size. The best solution is to ask your printer vendor for the driver supporting custom paper size. Of course, there is another alternative: change the paper size to the one your printer driver supported, such as A4.

3.2 Why the content of reports will become to black starting from 2nd page, when HP 4L, 4P, 5L, 6L used to print reports?

Please download the latest printer driver from http://www.hp.com

If you can't download the driver immediately, please try these two alternatives: use HP LaserJet driver or change the RAM of printer driver to 2MB.

3.3 When there is more than one page of invoices to be printed, why there is an error of sending paper?

Please change the driver to Epson LQ-570. It happened only in some MS Windows versions.

3.4 Why do Chinese characters become non readable characters, when EPSON LQ series used to print reports in MS Windows Chinese?

It may be English version printer driver be installed. Some models of EPSON LQ series will bundle with English version printer driver. After this driver installed, unidrv.dll of Chinese version will be covered. You can't recover even un-installation be executed. You can replace unidrv.dll in the directory of Windowsby unidrv.dll in MS Windows installation disk or other version MS Windows.
