The most important trait for a Software Engineer
When you are dealing with other people in life, you need to treat them how you expect to be treated. Projecting a positive attitude will most of the time reflect it back at you. However, the world can present you challenges, and you have to handle them graciously, especially if you’re a team leader (Carpenter, Bauer, & Erdogan, 2010).
As a software engineer, you build the roadmap for other software developers to follow when constructing a software product. While a balanced combination of all five personality traits: Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism is essential (2MinutePsychology, 2013), it is smart to adjust the dimension to suit based on the situation.
An essential personality trait as a software engineer would be openness. Being open with your team covers most of the spectrum. When you are engineering software, most of the time, you don’t have the complete picture instantly. On the one hand, this situation would require you to be open to receiving ideas, criticism, and suggestions. On the other hand, you will need to be transparent with your team about problems, evaluation, and cost (Iqbal, Aldaihani, Shah, 2019). Any software that does not establish this two-way route in openness will face many hurdles when dealing with his developers. While a software engineer might see the bigger picture, the developer sees the details and is the first in the line of offense (Iqbal, Aldaihani, Shah, 2019). Therefore, feedback from and to your developers is critical.
Openness can also streamline motivation, innovation, and trust. When you are honest, the team of developers wants to help you achieve the final goal because the benefits are clear on the table to everyone. Openness can also be a pillar for innovation, which is at the center of programming. The power of openness to achieve imagination and interest for your team can catalyze to produce the best product (Carpenter, Bauer, & Erdogan, 2010).
A smart team leader generally or a software engineer specifically can be at the center of innovation for their firm (Iqbal, Aldaihani, Shah, 2019). Through a routine practice of openness, the daily tasks at hand can make the workplace an enjoyable and pleasant bond based on trust and mutual respect.

The Greek Poleis
0Archaic Greece was the period that witnessed the rise of the polis states. Archaic Greece thrived during the era around 800-480 BC (Brand, n.d.). The founding of these city-states was a breakthrough for human civilization. A study of all the occurrences of the word polis in the Archaic and Classical sources showed that there are some 11,000 which shows the importance and relevance of this new way of life (Hansen, 2006). This period brought people into a well-structured community and away from poverty living in small rural villages as nomadic groups.
A new form of Government: During Greek dark ages people lived scattered in small farming villages (History.com Editors, 2010). The Archaic period brought two revolutionary forms of government, the Oligarchy in Sparta and the Democracy in Athens. Sparta was predominantly an Oligarchy where the military men in a democratic vote appointed the Ephors to supervise the kings and legislative branch of the government. Sparta had a complicated form of government that consisted of predominantly Oligarchy, Democracy, Monarchy and Tyranny (Hornblower, 2019).
On the other hand, Athenian democracy was separated into three parts: The Assembly, The Council, and The Courts. Athens was the first city-state to have a proper and effective form of democracy. It was very straight forward, mostly every Athenian citizen had a vote, the majority ruled (Brand, n.d.). There was abuse by wealthy aristocrats and noblemen but Athenian democracy was far from perfect with characteristics like slavery, gender bias, and control by rich aristocrats.
Community-based life: The community became more important than any individual. The loyalty to a polis central government was cherished as a central value of life. The new world they lived in within the city-state was regarded as a form of life-improving factor. In Sparta it is evident with practices like the Syssitia where Spartan men were eligible to join exclusive dining, men competed ferociously to get into a group (Brand, n.d.).
The people make up the polis: In contradiction with any prior civilization in Archaic Greece, the people were more important than temples, structures, and stones. People were the essence of the existence of the polis. This is evident during the evacuation of Athens “Themistocles organized the naval resistance and the evacuation of the city of Athens itself” (Brand, n.d.) it showed that Athens itself was not important as a polis that can be rebuilt but rather the people that lived in it.
Economic powerhouse: The polis city-state was an economic powerhouse promoting a marketplace for trade and agriculture (Hansen, 2006). The olive oil and pottery industries were booming and served as an export market to pay for the large amounts of grain that were used to feed the Athenian growing population (Brand, n.d.). Democratic Athens attracted immigrants that enriched the city intellectually and in trade. “They worked as merchants, craftsmen and in other lucrative trades such as philosophers who served as private tutors to the sons of wealthy Athenians” (Brand, n.d.).
In conclusion, Greece during the Archaic period did not always have the same shape and size polis. Poleis changed over time in shape, size, and location. Governance was also another aspect that had a progressive momentum at times and a controlled Monarchy in others (Brand, n.d.). Wars internally among Greeks and with external powers like the Persians were certainly the most important factor that shaped the change in the structure and governance of the city-state.

Searching through all columns in datagridview
0Assuming you are searching for the name John, the following procedure will search all existing columns regardless
Dim x As Integer = 0
While x < DataGridView1.Rows.Count
Dim y As Integer = 0
While y < DataGridView1.Rows(x).Cells.Count
Dim c As DataGridViewCell = DataGridView1.Rows(x).Cells(y)
If Not c.Value Is DBNull.Value Or Nothing Then
If CType(c.Value, String) = "John" Then
MessageBox.Show("Found!")
End If
End If
System.Math.Min(System.Threading.Interlocked.Increment(y), y - 1)
End While
System.Math.Min(System.Threading.Interlocked.Increment(x), x - 1)
End While
MessageBox.Show("Search complete!")
End Sub
Filtering a datagridview
0assuming you have a datagridview that has data in it.
you want to avoid recalling sql from the database & just want to filter the datagrid.
you can do the following, What you need (1 datagridview (data), 1 button (search), 1 textbox (string to search), 1 variable to precise the criteria your searching for)
Dim findcrit as string
Dim dt As DataTable = Ds_Pos.Employees
Dim dv As New DataView(dt)
Dim _RowFilter As String = ""
Dim _FieldType = dt.Columns(findcrit).DataType.ToString
Select Case _FieldType
Case "System.Int32"
_RowFilter = "convert(" & findcrit & ", 'System.String') like '" & Me.TextBox1.Text & "'"
Case "System.Int64"
_RowFilter = "convert(" & findcrit & ", 'System.String') like '" & Me.TextBox1.Text & "'"
Case "System.Double"
_RowFilter = "convert(" & findcrit & ", 'System.String') like '" & Me.TextBox1.Text & "'"
Case "System.String"
_RowFilter = findcrit & " like '" & TextBox1.Text & "*'"
End Select
dv.RowFilter = _RowFilter
EmployeesDataGridView.DataSource = dv
The cases are to cast the type of variable from any type to string because you can only use the method on string data types.
the idea is to move the content to a data table then filter then return it back to the datatable.
using c# and vb in the same web project
0Can you have both c# and visual basic in the same web site project?
Definitely! It simply wouldn’t make sense from a new project standpoint, code reviews, coding standards, continuity, project maintenance, etc.
however, people still want it. to-date i never really tried (and that’s been my answer). i was presented with a usable scenario of why you may need (not want, need) to do this, so i finally tried it. the answer: yes…kinda…sometimes.
let’s assume we have a web site structure like this:
we have the App_Code folder and a .cs and a .vb file in the same projects (separated into sub-folders). note that the project sees them as folders (yellow folder icon) in the special folder. each class within there basically has a “hello world” function only, like this in the c# file:
public string SayHelloCS()
{
return "Hello from CS";
}
and the visual basic file has a similar function emitting "Hello from VB."
now, if you run default.aspx in this structure, this is what you will see:
The files ‘/WebSite5/App_Code/VBCode/Class2.vb’ and ‘/WebSite5/App_Code/CSCode/Class1.cs’ use a different language, which is not allowed since they need to be compiled together.
interesting? probably not, but it makes sense…so how do we overcome. we use a configuration option called codeSubDirectories. here’s what we need to add to our <compilation> node in our web.config:
<compilation debug="false">
<codeSubDirectories>
<add directoryName="VBCode"/>
<add directoryName="CSCode"/>
</codeSubDirectories>
</compilation>
once we add those codeSubDirectory nodes, let’s “look” at what the project structure looks like now:
as you can see the code folders are now “special” in the eyes of visual studio. now if we browse default.aspx we will see:
Hello world from CS. Hello world from VB
Custom error pages using .htaccess
0We’ve all seen the dreaded Error 404 message – the result of broken links and mistyped URLs. You’ve probably been on some websites where the error pages are customised with their own logo and message, and I’m sure you’ll agree that it looks far more professional than the standard one.
In this article we’ll show you how to use Apache’s .htaccess file to make your own customised error 404 pages.
Create a new text file on your computer, and call it “htaccess.txt”. Enter the following lines:
<Files .htaccess>
order allow,deny
deny from all
</Files>
Now you need to create the 404 page. Make a new web page called “error404.htm” and enter “This is my 404 page”. Enter it a few dozen times, as Internet Explorer won’t display it unless the file is over 512 bytes.
Once it’s done, login to your webspace with your FTP client, and create a new folder called “errordocs”. Upload the file “error404.htm” to this directory. Upload “htaccess.txt” to the root of your webspace and rename it to “.htaccess” — there’s no .txt at the end, no name in front, just “.htaccess”. If the file seems to vanish don’t worry, some FTP clients don’t display it — the file’s still there.
ErrorDocument 404 /errordocs/error404.htm
The first part stops people viewing your .htaccess file. The second part tells Apache to redirect any 404 errors to the file “error404.htm”.
Split Command Sample Code (VB NET)
0Preparations : 1 Textbox and 1 Button
Code :
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim strInput As Array 'make array variable
Dim strResult1 As String 'text variable
Dim strResult2 As String 'another text variable
Try
strInput = Split(TextBox1.Text, " ")
'split the textbox if there is space.
'you can also use chr(32) to replace " "
strResult1 = strInput(0) 'split first text
strResult2 = strInput(1) 'split second text
MsgBox(strResult1 + strResult2)
'combine first and second text with no space
Catch ex As Exception
End Try
End Sub
Test the code, type space character between 2 words :
What we have done here?
Explanation :
- We have 2 words with a space character (“jenni” and “fer”)
- We split those words using “Split” command into array, the process is identified with space character, so we had 2 lines.
- We combine those words back together in one line, but this time with no space character in it.
Getting IP Address (VB NET 2008)
0Note: if you’re not a beginner and just want to look for the code, you may skip these 1-6 steps and go straight to the sample code.
1) Let’s start with new project “Windows forms application”
2) Put one TextBox and a Button in the Form
3) Add reference to our project by clicking : Project –> Add Reference
4) Scroll down and select “System.Net” as our reference. Click OK to proceed.
5) Open the Coding Window or you can just simply double click on the Button1, or you can also use F7 for shortcut.
6) Type “Imports System.Net” in General as shown in the picture below
7) Now the code part, on your Button1_Click event add this code as shown in the picture below
8) Run your program or press F5
