A programming language is a formal constructed language designed to communicate instructions to a machine, particularly a computer. Thousands of different programming languages have been created, mainly in the computer field, and many more still are being created every year. The description of a programming language is usually split into the two components of syntax (form) and semantics (meaning). Some languages are defined by a specification document (for example, the C programming language is specified by an ISO Standard), while other languages (such as Perl) have a dominant implementation that is treated as a reference. Some languages have both, with the basic language defined by a standard and extensions taken from the dominant implementation being common.

Hello Guys,

I developed a simple project where I embebed an IE into a panel, it is ok so far.
I have two problems with my small project:

1) left and top of my IE created into a panel, I can't set it to left=0 and top = 0
2) I would like to have my IE created into my panel without any borderstyle. For this, I tried that command:
SetWindowLong(ie.Handle,GWL_STYLE,  GetWindowLong(ie.Handle,GWL_STYLE) and (not WS_CAPTION) or WS_THICKFRAME);

But I haven't had any success yet.
Web2.rar
the project has only one unit.pas and you can open it in any Delphi version. I use Delphi 2007.

After opening the project, click on the button Browse, it will create a IE into panel1, there is another button named "Mostra Pn" where a panel3 will hide or not and the IE in panel1 should resize automatically.

my code
procedure TForm1.BitBtn1Click(Sender: TObject);
begin
  ie := CreateOleObject('InternetExplorer.Application');
  windows.setparent(ie.hwnd, panel1.handle);
  s:='http://www.microsoft.com';
  s:='https://mercado.khan.com.br/qualidade/historico.aspx';
  ie.Navigate(s);

  ie.fullscreen:=false;
  ie.MenuBar := False;
  ie.AddressBar := False;
  ie.Resizable := false;
  ie.StatusBar := True;
  ie.ToolBar := 0;

  ie.top    := 0;
  ie.left   := 0;
  ie.Width  := panel1.Width;
  ie.Height := panel1.Height+27;


  ie.visible := True;
// SetWindowLong(ie.Handle,GWL_STYLE,  GetWindowLong(ie.Handle,GWL_STYLE) and (not WS_CAPTION) or WS_THICKFRAME);  // I

As will soon become clear, I'm not a master of Git or even Gitkraken. As such, I just have a hotfix, a master and a feature branch. I make changes in hotfix, commit, push, and merge into master (which I then also push). So far I've endeavored not to get more complicated than this.

Even my one feature branch is a bit cowardly, in that that I still keep my feature work separate (in separate files/directories) from my working files, and consistently merge master into the feature branch so I don't lose all the site's hotfixes – all so that my crucial site files are kept whole and untouched regardless of branch. I consider this an intermediate practice as I continue to maintain the site while getting my head around Git. Since now I'm having this bizarre issue, I can see why I hadn't taken that leap yet. Apparently I'm indeed not ready to power-use Git or Gitkraken.

This morning, I did some work on hotfix, and merged it into master. No issue. Then I tried to switch to the feature branch (which I hadn't been in for weeks as it has been all about hot fixes lately), and all hell broke loose. Gitkraken throws the error: "Checkout failed. Could not remove [swf file - one that was there long before my last commit] Operation not permitted." What? Web searches with these key phrases turned up literally nothing... making me the first person to have this happen, I guess.

Then!... immediately, still in hotfix and having done nothing further, suddenly there are 27 file changes staged …

Hi Experts

Could you point a way to join multiple .CSV(s) files into one?

I had tried  to use TXTCollector but it doesn't work fine everytime.

Sometimes this error occurs:
[Error] - File could not be written...

Amazingly the files were generated the same way.

I've been looking into other languages and was wondering which one is the best for locking down and protecting your source code.

Is it even possible to encrypt/lock your source code in any language?

I don't want to learn a language, invest years of time developing something, then have someone immediately copy my source and sell a derivative before I can turn a profit on it.

HI,
Is there any website where one can post there understanding of computer science concepts or explain them and then user can ask questions. Although expert exchange also has article section.
But i want to specifically do it for Java concepts Java 8 features etc.
The idea is to feel motivated to study it... as it helps learning the material in a quicker way
Any alternative suggestions
Thanks

Hi, I'm documenting a change in a web page (not written by my company)and encountered the following snippet. What language is it? JavaScript? Thanks.

i have above code in a method.

i never saw if else inside a catch in earlier.

why some one use if else inside catch
when the catch is thrown as try block simply return true or false

when it has 999 or 888 etc value in the xyze exception

please advise

one registerPhone flow goes through 30 stored procedures. Each stored proc connecting database individually and taking 100 milli seconds to connect.

so 30 multipled by 100 total 3000 milli seconds wasted due to this.

can i make all 30 stored procedures into one call so that only one database connection happens for 100 milli seconds

Like to save those 3000 milli seconds when i can do only with 100 milli seconds

Hi Experts,

there are two approached to pass sheet names vaue
1st approach:

JRXlsExporter exporter = new JRXlsExporter(); exporter.setParameter( JRXlsAbstractExporterParameter.SHEET_NAMES, new String[] {"first","second","third"} ); 

Open in new window


cant we pass this value as parameter in java?

this way(1st approach) i am unable to follow because i am sheduling report for a specificdate. and passing few parameter inputs as well for the same report.

sample:
Util.getParamString(stringBuilder, "GENERATEDON", Date);//similarly few more params i am passing

Open in new window


2nd approach:

iam setting in the report properties like below(2nd approach): Property Name = "net.sf.jasperreports.export.xls.sheet.names.all"

 Property Value = "first/second/third"

is there any chance to pass this property value as dynamic.?

I have tried like below as not works for me

<line> 
<reportElement x="0" y="-1" width="1" height="1"> 
<propertyExpression name="net.sf.jasperreports.export.xls.sheet.name"><![CDATA[$F{course_name}]]></propertyExpression> 
</reportElement> 
</line>

Constructors are not inherited:
The sub class cannot inherit constructors from its super class. Consider the following example:
1
2
3
4
5
6
7
8
9
10
11
public class Super {
    protected String text;
 
    public Super(String text) {
        this.text = text;
    }
}
 
public class Sub extends Super {
 
}
We can create a new instance of Super like this:
1
Super super = new Super(“Hello”);   //OK
But we cannot do the same for the Sub class:
1
Sub sub = new Sub(“Hello”); //Compile error, since constructor is not inherited
The solution is to write a constructor for the sub class and call the super’s constructor, for example:
1
2
3
4
5
6
public class Sub extends Super {
 
    public Sub(String text) {
        super(text);
    }
}

https://www.codejava.net/java-core/the-java-language/12-rules-and-examples-about-inheritance-in-java

i wrote as below

package SuperSub;
public class Super {
    protected String text;
 
    public Super(String text) {
        this.text = text;
    }
}
 

Open in new window


package SuperSub;
public class Sub extends Super {
	//Super super = new Super(“Hello”);
}

Open in new window


i am getting error in line 2 of Sub class
Implicit super constructor Super() is undefined for default constructor. Must define an explicit constructor
package SuperSub;
public class Sub extends Super {

	public Sub(String text) {
		super(text);
		// TODO Auto-generated constructor stub
	}
	//Super super = new Super(“Hello”);

above is fine though not sure why i cannot just have Sub empty class?

The super keyword:
In Java, the superkeyword is used to access members of the super type from the sub type. For example:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
public class Super {
    protected void bar() {
        System.out.println("Super.bar()...");
    }
 
}
 
public class Sub extends Super {
    public void bar() {
        System.out.println("Sub.bar()...");
    }
 
 
    public void test() {
        super.bar();
        this.bar();
    }
}
Here, we can see that both classes have a method called bar() (overriding). Therefore, if we want to invoke the super’s version of the bar() method, the super keyword is used.
