Hi guys. I spended all day for listening podcasts about japan live. I want to go to japan, if you want to sponsor me you can send me money(for more information chat via icq:444220842) :) or give me freelance work(rails, asp.net, java or other technologies, preference to c/c++ qt job) :)

See you later.

Write simple expander for text area(Very simple effect).

Today I started to recollect my knowledge in javascript and for simple training I wrote expander for html element textarea.

// library/expander.js
expander = {
_init : function() {
var elements = document.getElementsByTagName('textarea');
for(var i = 0; i < elements.length; i++)
{
var area = elements[i];
if (area.className.search(/\bexpander\b/) != -1)
{
expander.addActions(area);
}
}
},

addActions : function(area) {
area._rows = area.rows;
area._cols = area.cols;

area.onkeyup = expander._onkeyup;
area.onfocus = expander._onfocus;
},
_onkeyup : function(e) {
var area = e.target;
if ((area.value.length - area.rows) / area.cols > area.rows)
{
var count = (area.value.length - area.rows) / (area.cols * area.rows);
var lines = area.value.split('\n');
var line = lines[lines.length - 1];
if (line.length > area.cols)
{
var n = Math.floor(line.length / area.cols);
for(var i = 0; i < n; i++)
{
lines[lines.length - 1 + i] = line.substring(0, area.cols);
line = line.substring(area.cols, line.length);
}
if (line.length != 0)
{
lines[lines.length - 1 + i] = line;
}
area.value = lines.join('\n');
}
else
{
area.value += '\n';
}
area.rows += count;
}
else
{
if (area.value.length + area.cols <= area.cols * area.rows)
{
var count = area.cols * area.rows / (area.value.length + area.cols);
area.rows -= count - 1;
}
}

area._rows = area.rows;
area._cols = area.cols;
},
_onfocus : function(e) {
var area = e.target;

area.rows = area._rows;
area.cols = area._cols;
}
};

window.onload = expander._init;

Today I found very good information about audit in sharepoint,

3 exam is approved by lecturer

It's beatifull day today)). Now I'll start to prepare for my evening basketball because 3 examination is approved.

exams))

Now I'm preparing for my exams. I try to inside out learn all having information about politology, sometimes I'm parsing wiki for additional knowlegdes but I haven't time, aaaa what do I have to do???

Music for this day.)

Information for anonymous readers.)

You might have noticed that my blog are writting with long break and sometimes with extrimly posting information(such as that day). Now I'm studing and have't time to write more pretty post. But фs soon as the opportunity I'll start to type more intresting and .NET article)).

The day after tomorrow)

Today I take my first task in new project.
M: "Go to read books about features in SharePoint;)"
One of the most abilities given to me that's chance working with ASP.NET and javascript, css and other crap) as you know it's black line for me.

Please approve my death.

Now I'm sitting on new project about 3 days.
1 day - Aaahhh, My death is so closely;) (I started to learn share point technologies:)).
2 day - all tired, we are alone in this cruel world.
3 day - I feel good, 6 hours and I'm going to sugar holiday.

Before using the program, you have to create flopic.cfg file that's contain data(" ", between params olny space).

sorttable.js bugs in ASP.NET with ms ajax

Hi all, 1 month ago I worked in project, where I wrote custom widget(table with header sort event).
And I downloaded very pretty javascript library(sorttable, http://www.kryogenix.org/code/browser/sorttable/), but I couldn't understand, why when I include this library in page with Ms Ajax control's, exceptions try to fuck my browser and brain.
After google, I found blog of japan guy(don't remember link, butthankful for him) some information about forEach method, that's uses in MS Ajax and sorttable library. For fixing this bug, you may try to replace forEach method in sorttable library to simple for loop, example (in init()):

/*forEach(document.getElementsByTagName('table'), function(table) {
if (table.className.search(/\bsortable\b/) != -1) {
var index = table.id.indexOf("_header");
var sortingFields = table.id.substring(0, index);
sorttable.makeSortable(table, sortingFields);
}
}); */

for(i=0;i < document.getElementsByTagName('table').length;i++)
{
table=document.getElementsByTagName('table')[i];
if (table.className.search(/\bsortable\b/) != -1) {
var index = table.id.indexOf("_header");
var sortingFields = table.id.substring(0, index);
sorttable.makeSortable(table, sortingFields);
}
};

That's all, thanks for reading.

Day of qt

Not so long ago I've start to write different programmes based on c++ qt framework.
It's very great full, very thoughtful, very similar to C#, java. But Qt haven't event model or delegate model. But it have more flexible model, SIGNALS and SLOTS.
For example:
You have model (A) and (B) and (C)
(A) have to send data to model (B) and (C).
and you write:
QObject::connect(A, SIGNAL(sendDataSignal()),
B, SLOT()));
You can also subscribe for example: signal to signal, signal to slot. It's build a chain.
It hasn't long been seen nothing convenient.

Hi, all.

It's my the first blog but not last. I'm tring to write sometimes artices that's devoting .NET programming. Sometimes .NET is voodoo. And you can see what I mean).
