**** XSQLMENU: An X-windows frontend for the MiniSQL database engine. ****
**** (c) 1996 Kees Lemmens; TU Delft The Netherlands. ****
**** Version 1.01 (BETA release) ****
General:
The popular MiniSQL database engine by David Hughes Technologies in
Australia is a simple but very robust database engine that supports also
remote access through TCP sockets. The only problem is that it lacks a good
and friendly user interface.
As we planned to make our student administration a little more sophisticated
(up to now we used ASCII files ...) I decided to use the nice Xforms package
by T. Zhao and M. Overmars and try to build such a good, flexible and robust
interface.
This fits into my opinion that although the Unix OS is a very powerful and
reliable OS, it won't be able to hold against the pressure of less reliable
systems if it doesn't come up with more user friendly interfaces.
I hope this package can be of help to setup a good looking and easy to use
database environment on Unix systems like Linux.
WARNING: This package cannot run without having the the msqld (MiniSQL
daemon) running on one of your systems (which not necessarily has to be the
same system you're runing xsqlmenu on !). The msqld it is available on most of
the large sites. (try for more info about MiniSQL http://Hughes.com.au/ )
Install:
The source code is available as Xsqlmenu_1.01s.tar.gz and a distribution
with binaries for Linux is available as Xsqlmenu_1.01LinuxBin.tar.gz.
There are 2 versions in the binary Linux package:
- a statically linked version that can run on any Linux PC (with ELF)
- a dynamic version that will only run if you have somewhere libXforms.so.0.*
- in your library search path.
You only need to have the binary somewhere in your searchpath. Currently no
other files are needed to run this program.
A few notes:
- Don't forget to select a MSQL database server (if not selected it tries to
connect to a server on the local host), a database and a table before
starting to make any selections or else you won't be able to open any of the
subwindows. ( Message: "Select a table first !")
- The primary key field is shown in red, all others fields in black. The
primary key can't be modified with xsqlmenu (although the Mini SQL database
can do that without problems): if you want to change the primary key, you'll
have to delete the record and insert a new one. However, you can copy fields
from one window to another by one using the mouse.
I deciced to keep the primary key field locked to avoid confusion with the
users: It's easy to lose important information if you change the primary key
by accident as I found out here.
- It is no problem to have browsers and search screens open from different
tables or even databases simultaneously. But, if you select a new database
it will be impossible to modify or select records from windows that still
work with the previous database.
If you want to update or modify those records you should simply reselect the
old database and the previous connection will be reestablished.
- If you select a record from the browser and modify or delete it, the
browser won't be updated with the new information: it works on a static
selection that is stored locally. However, every time you select a record
for modification it will be reread from the database server to ensure you
have the latest version.
- In the SQL Query window you can enter a free SQL query. However, I
haven't checked extensively what happens if you use anything else but SELECT
queries. Also, because strange things could happen if you select joins from
several tables or only select a few fields I decided to block the modify
option in the browser. It is simply too difficult to decide what information the
user wants to change in what database.
I considered to enable the 'modify' option for the SQL Query command (it's
only 1 switch in the code !), but I really think this can be too tricky. If
you want to modify information: just select the appropriate record on the
primary key (with the Modify button in Main Window) or use a Search Form or
the normal Browser (Show All).
- In the browser you can change the fontsize. However, if the font actually
changes with every step depends on the setup of your display font
capabilities (scaled fonts, fixed fonts etc.). Also, there is no way to
scroll horizontally yet as the Xforms browser simply doesn't provide that
option. (although there exists a function to "x_offset" a browser !) However,
the browser window is scalable and also the fontsize can be changed, so in
most cases you'll be able to see all information without too many
difficulties.

A much more important factor in the social movement than those already mentioned was the ever-increasing influence of women. This probably stood at the lowest point to which it has ever fallen, during the classic age of Greek life and thought. In the history of Thucydides, so far as it forms a connected series of events, four times only during a period of nearly seventy years does a woman cross the scene. In each instance her apparition only lasts for a moment. In three of the four instances she is a queen or a princess, and belongs either to the half-barbarous kingdoms of northern Hellas or to wholly barbarous Thrace. In the one remaining instance208— that of the woman who helps some of the trapped Thebans to make their escape from Plataea—while her deed of mercy will live for ever, her name is for ever lost.319 But no sooner did philosophy abandon physics for ethics and religion than the importance of those subjects to women was perceived, first by Socrates, and after him by Xenophon and Plato. Women are said to have attended Plato’s lectures disguised as men. Women formed part of the circle which gathered round Epicurus in his suburban retreat. Others aspired not only to learn but to teach. Arêtê, the daughter of Aristippus, handed on the Cyrenaic doctrine to her son, the younger Aristippus. Hipparchia, the wife of Crates the Cynic, earned a place among the representatives of his school. But all these were exceptions; some of them belonged to the class of Hetaerae; and philosophy, although it might address itself to them, remained unaffected by their influence. The case was widely different in Rome, where women were far more highly honoured than in Greece;320 and even if the prominent part assigned to them in the legendary history of the city be a proof, among others, of its untrustworthiness, still that such stories should be thought worth inventing and preserving is an indirect proof of the extent to which feminine influence prevailed. With the loss of political liberty, their importance, as always happens at such a conjuncture, was considerably increased. Under a personal government there is far more scope for intrigue than where law is king; and as intriguers women are at least the209 equals of men. Moreover, they profited fully by the levelling tendencies of the age. One great service of the imperial jurisconsults was to remove some of the disabilities under which women formerly suffered. According to the old law, they were placed under male guardianship through their whole life, but this restraint was first reduced to a legal fiction by compelling the guardian to do what they wished, and at last it was entirely abolished. Their powers both of inheritance and bequest were extended; they frequently possessed immense wealth; and their wealth was sometimes expended for purposes of public munificence. Their social freedom seems to have been unlimited, and they formed combinations among themselves which probably served to increase their general influence.321 The old religions of Greece and Italy were essentially oracular. While inculcating the existence of supernatural beings, and prescribing the modes according to which such beings were to be worshipped, they paid most attention to the interpretation of the signs by which either future events in general, or the consequences of particular actions, were supposed to be divinely revealed. Of these intimations, some were given to the whole world, so that he who ran might read, others were reserved for certain favoured localities, and only communicated through the appointed ministers of the god. The Delphic oracle in particular enjoyed an enormous reputation both among Greeks and barbarians for guidance afforded under the latter conditions; and during a considerable period it may even be said to have directed the course of Hellenic civilisation. It was also under this form that supernatural religion suffered most injury from the great intellectual movement which followed the Persian wars. Men who had learned to study the constant sequences of Nature for themselves, and to shape their conduct according to fixed principles of prudence or of justice, either thought it irreverent to trouble the god about questions on which they were competent to form an opinion for themselves, or did not choose to place a well-considered scheme at the mercy of his possibly interested responses. That such a revolution occurred about the middle of the fifth century B.C., seems proved by the great change of tone in reference to this subject which one perceives on passing from Aeschylus to Sophocles. That anyone should question the veracity of an oracle is a supposition which never crosses the mind of the elder dramatist. A knowledge of augury counts among the greatest benefits222 conferred by Prometheus on mankind, and the Titan brings Zeus himself to terms by his acquaintance with the secrets of destiny. Sophocles, on the other hand, evidently has to deal with a sceptical generation, despising prophecies and needing to be warned of the fearful consequences brought about by neglecting their injunctions. The stranger had a pleasant, round face, with eyes that twinkled in spite of the creases around them that showed worry. No wonder he was worried, Sandy thought: having deserted the craft they had foiled in its attempt to get the gems, the man had returned from some short foray to discover his craft replaced by another. “Thanks,” Dick retorted, without smiling. When they reached him, in the dying glow of the flashlight Dick trained on a body lying in a heap, they identified the man who had been warned by his gypsy fortune teller to “look out for a hidden enemy.” He was lying at full length in the mould and leaves. "But that is sport," she answered carelessly. On the retirement of Townshend, Walpole reigned supreme and without a rival in the Cabinet. Henry Pelham was made Secretary at War; Compton Earl of Wilmington Privy Seal. He left foreign affairs chiefly to Stanhope, now Lord Harrington, and to the Duke of Newcastle, impressing on them by all means to avoid quarrels with foreign Powers, and maintain the blessings of peace. With all the faults of Walpole, this was the praise of his political system, which system, on the meeting of Parliament in the spring of 1731, was violently attacked by Wyndham and Pulteney, on the plea that we were making ruinous treaties, and sacrificing British interests, in order to benefit Hanover, the eternal millstone round the neck of England. Pulteney and Bolingbroke carried the same attack into the pages of The Craftsman, but they failed to move Walpole, or to shake his power. The English Government, instead of treating Wilkes with a dignified indifference, was weak enough to show how deeply it was touched by him, dismissed him from his commission of Colonel of the Buckinghamshire Militia, and treated Lord Temple as an abettor of his, by depriving him of the Lord-Lieutenancy of the same county, and striking his name from the list of Privy Councillors, giving the Lord-Lieutenancy to Dashwood, now Lord Le Despencer. "I tell you what I'll do," said the Deacon, after a little consideration. "I feel as if both Si and you kin stand a little more'n you had yesterday. I'll cook two to-day. We'll send a big cupful over to Capt. McGillicuddy. That'll leave us two for to-morrer. After that we'll have to trust to Providence." "Indeed you won't," said the Surgeon decisively. "You'll go straight home, and stay there until you are well. You won't be fit for duty for at least a month yet, if then. If you went out into camp now you would have a relapse, and be dead inside of a week. The country between here and Chattanooga is dotted with the graves of men who have been sent back to the front too soon." "Adone do wud that—though you sound more as if you wur in a black temper wud me than as if you pitied me." "Wot about this gal he's married?" "Don't come any further." "Davy, it 'ud be cruel of us to go and leave him." "Insolent priest!" interrupted De Boteler, "do you dare to justify what you have done? Now, by my faith, if you had with proper humility acknowledged your fault and sued for pardon—pardon you should have had. But now, you leave this castle instantly. I will teach you that De Boteler will yet be master of his own house, and his own vassals. And here I swear (and the baron of Sudley uttered an imprecation) that, for your meddling knavery, no priest or monk shall ever again abide here. If the varlets want to shrieve, they can go to the Abbey; and if they want to hear mass, a priest can come from Winchcombe. But never shall another of your meddling fraternity abide at Sudley while Roland de Boteler is its lord." "My lord," said Edith, in her defence, "this woman has sworn falsely. The medicine I gave was a sovereign remedy, if given as I ordered. Ten drops would have saved the child's life; but the contents of the phial destroyed it. The words I uttered were prayers for the life of the child. My children, and all who know me, can bear witness that I have a custom of asking His blessing upon all I take in hand. I raised my eyes towards heaven, and muttered words; but, my lord, they were words of prayer—and I looked up as I prayed, to the footstool of the Lord. But it is in vain to contend: the malice of the wicked will triumph, and Edith Holgrave, who even in thought never harmed one of God's creatures, must be sacrificed to cover the guilt, or hide the thoughtlessness of another." "Aye, Sir Treasurer, thou hast reason to sink thy head! Thy odious poll-tax has mingled vengeance—nay, blood—with the cry of the bond." HoME古一级毛片免费观看
