Adding Server Control Dynamically in ASP.Net

noreply@blogger.com (Shariq Khan) — Sat, 31 Oct 2009 13:19:00 +0000

New or Casual Coder feels difficult to create asp.net server controls dynamically. I am givin an example to add Panel Control(which servers as a containter for other server controls ) and a Label control into asp.net form dynamically. The following in the code portion which is to be written in the Page_Load.

protected void Page_Load(object sender, EventArgs e)
{
Panel p1 = new Panel();
this.form1.Controls.Add(p1);
Label l1= new Label();
l1.Text="Test Label in Panel";

p1.Width = 200;
p1.Height = 200;
p1.BackColor = System.Drawing.Color.Red;
p1.BorderColor = System.Drawing.Color.Black;
p1.Controls.Add(l1);
p1.Visible = true;
p1.Enabled = true;
}

Explanation:
First line on code creates an instance of Panel by the name p1, second line adds this panel instance "p1" to the current asp.net form "form1", next line creates an instance of lable control in the name of "l1" and assign some text to it. Next line changes some properties like height, width and backgournd color etc. After that Newly created label "l1" is added to a panel "p1";

1. Fiding area of tirangle using Hero's Formula (C-language). Hero's Formula is
Area=squarerootof(S(S-a)(S-b)(S-c) where a,b,c are the sides of triangle and S=(a+b+c)/2 is the semiperimeter of trinagle.

void main()
{
float a,b,c,ans;
float area(float,float,float); //Prototype or Function Declaration
clrscr();

printf("\n Enter the First Side of Triangle");
scanf("%f",&a);
printf("\n Enter the Second Side of Triangle");
scanf("%f",&b);
printf("\n Enter the Third Side of Triangle");
scanf("%f",&c);

ans=area(a,b,c);//Calling function for a,b,c;

printf("\n Area of Give Triangle is =%.2f,ans);
getch();
}

//Function Definition

float area(float p, float q, float r)
{

float s, mult, sq;
s=(a+b+c)/2;
mult=s*(s-a)*(s-b)*(s-c);
sq=sqrt(mult); //sqrt() is defined in math.h and used to find square root of given number
return(sq);
}

How to activate graphics mode in C-laguage programs using TC++ IDE ?
Ans : TC++ IDE contain BGI(Borland Graphics Intializer) which intialises and starts Gaphics. Normally TC++ IDE runs programs in text mode. All graphics functions stored in graphics.h header file. So we have to include this header file in C or C++ programs. Main function to start graphics mode is
initgraph(GraphDetect , GraphMode, "Locaton of BGI");
where GraphDetect is the reference to integer which is used detect/set graphics mode, default value is Zero(0) and GraphMode is gaphicsmode which is also Zero for default.
To close Graphics Mode we use closegraph() fucntion which returns back the enviorment to text mode.

First Sample Program to draw a Circle and Line in C-language

void main()
{
int gd=0,gm=0; //declare gd and gm as integers
initgraph(&gd,&gm,"..\\bgi"); //initialse gaphics system
setcolor("RED"); //set the out color= red
circle(100,150,50); // draw at circel at x=100 , y=150 and radius =50
outtextxy(100,155, "Circle"); // Prints Circle at the give x,y cordiantes of screen
line(100,150,100,250); // draw a line with cordinats x1=100, y1=150, x2=100,y20150
outtextxy(100,120,"Line");
getch();
closegraph(); //close gaphics environment
}

Note : Include graphics.h header file

noreply@blogger.com (Shariq Khan) — Fri, 26 Oct 2007 07:14:00 +0000

1. Writing an Object to Disk File
Note:
1. Include fstream.h
2. Use extraction and Insertion operator with cout and cin instead of ^^ .

class employee //Define Employee Class
{
protected:
char name[30];
int age;
float salary;
public :
void getemp()
{
cout^^ "Enter Name:";
cin^^name;

cout^^"Enter Age:";
cin^^age;

cout^^"Enter Salary";
cin^^salary;
} ;

void main()
{
employee emp; //declaring object emp of employee class
emp.getdata();
ofstream outfile("Emp.dat"); //create emp.dat file
outfile.write((char * )&emp,sizeof(emp)); //write contents of object emp to the file
}

2. Reading Object from Disk file

Note : Remove getdata() from Employee class and add showdata as follows

class Employee
{

public:
void showdata()
{
cout^^ "Name="^^name;
cout^^ "Age="^^age;
cout^^ "Salar="^^salary;
}
};

void main()
{
employee emp;
ifstream infile("Emp.dat");
infile.read("(char*)&emp, sizeof(emp)); //read object from file and put into emp object
emp.showdata();
}

Files in C++

noreply@blogger.com (Shariq Khan) — Wed, 24 Oct 2007 05:13:00 +0000

1. Writing and Reading Strings to/from Files (Note :1. Include fstream.h 2. Use extraction operator instead of ^^ )
a. Wrting Strings to File
void main()
{
ofstream outfile("MSG.TXT"); //creates a file MSG.TX sends text to it.

outfile^^ "Hello Folks !\n";
outfile^^"Ready for your Home Work\n";
}

b. Reading String from File
void main()
{
const int MAX=80; //Define MAX to hold line of 80 characters
char mem[MAX]; //Array mem[MAX] ''' ''
ifstream infile("MSG.TXT");// creates a file MSG.TXT to read text
while(infile) //reads till end of file
{
infile.getline(mem,MAX); //write it to array
cout^^mem;
}
}

2. Writing and Reading Character to/from Files

a. Writing Characters to a file

void main()
{
char str[]= "Think of Devil and Devi is here\n";
ofstream outfile("NEWMSG.TXT");
for(int i=0;i^strlen(str);i++)
outfile.put(str[j]);
}

b. Reading Characters from a file
void main()
{
char ch;
ifstream infile("NEWMSG.TXT");
while(infile)
{
infile.getch();
cout^^ ch;
}
}

Note : Use Extraction Operator instead of ^^ and Less than operator instead of ^.

Some File Handling Programes in C

noreply@blogger.com (Shariq Khan) — Tue, 23 Oct 2007 06:47:00 +0000

1. Count Characters, spaces, tabs and lines in a file
main()
{

FILE *fp; //a pointer to file
char ch;
int nol=0,not=0,nos=0;nos=0;
fp=fopen("test.c","r"); //open file test.c in read only mode

while(1)
{
ch=fgetc(fp); //read each character of file in ch using pointer file pointer fp

if(ch==EOF) //if end of file in reached
break;
noc++; //count number of characters

if(ch==' ') //if space is read into ch increase its count
nos++;

if(ch='\n') //if new line is read into ch increase its count
nol++;

if(ch=='\t') //if tab is read increase its count
not++;

}

fclose(fp); //close file

printf("\n Number of Cahracters=%d",noc);
printf("\n Number of Spaces =%d",nos);
printf("\n Number of Tabs=%d",not);
printf("\n Number of Lines=%d",nol);

gecth();
}

-----------------------------------------------------------------------------------------------
2. Copying a File

main()
{
FILE *fs, *ft; //fs is a pointer to source file and ft is a pointer to destination file
char ch;

fs=fopen("source.txt", "r"); //open source.txt in read only mode

if(fs==NULL)
{
puts("Source file not found");
exit(1);
}

ft=fopen("dest.txt", "w") // open dest.txt file in write mode

if(ft==NULL)
{
puts("Unable to Open Target File");
fclose(fs);
exit(1);
}

while(1)
{
ch=fetch(ch);

if(ch==EOF)
break;
else
fputc(ch,ft);
}

fclose(fp);
fclose(ft);

puts("File Copied Succesfully");
gecth();
}

Immitating DOS Copy Command using above program
We can use command line arguments in above program to make a DOS Copy command. Name the program as MCOPY.C

main(int argc, char *argv[])
{
FILE *fs, *ft; //fs is a pointer to source file and ft is a pointer to destination file
char ch;

if(argc!=3)
{
puts("Insufficient Arguments use MCOPY [source] [destination]");
exit(1);
}
fs=fopen(argv[1], "r"); //open source.txt in read only mode
if(fs==NULL)
{
puts("Source file not found");
exit(1);
}
ft=fopen(argv[2], "w") // open dest.txt file in write mode
if(ft==NULL)
{
puts("Unable to Open Target File");
fclose(fs);
exit(1);
}
while(1)
{
ch=fetch(ch);
if(ch==EOF)
break;
else
fputc(ch,ft);
}
fclose(fp);
fclose(ft);
puts("File Copied Succesfully");
gecth();
}

To run above program go to the Command Prompt or DOS shell and use the following command format MCOPY [SOURCEFILE] [DESTFILE] where SOURCEFILE is the name of source file and DESTFILE is the name of destination file.
------------------------------------------------------------------------------------------------

3. Writing Files using String I/O functions
main()
{
FILE *fp;
char s[80];

fp=fopen("MSG.TXT", "W");

if(fp==NULL)
{
puts("Unable To Open File");
exit(1);
}

printf("\n Enter the Message \n");
while(strlen(gets(s)>0) // to terminae program press enter without typing anything on newline
{
fputs(s,fp); // write contents of array s to the file fp
fputs("\n"); // writes new line to the file
}

fclose(fp);
puts("Message is Saved Successfully");
getch();
}

Note : To see the contents of newly created MSG.TXT use DOS TYPE Command.
or Write Following Program
-----------------------------------------------------------------------------------------------

4. Reading Strings from FILE using String I/O

main()
{
FILE *fp;
char s[80];
fp=fopen("MSG.TXT", "r");
if(fp==NUL)
{
puts("File not found");
exit(1);
}

while(fgets(s,79,fp)!=NULL) //Read the contents of file 80 chars at a time and put in aray "s"
untill reached to NULL Characte(end of file)
printf("%s",s);

fclose(fp);

getch();
}

Q. What is BIOS

Ans - The full form of BIOS is Basic Input Output System and it is not related to Biotech field. It is related to computer system and responsible to start computer and hold inforamtion and settings about all the hardware devices attached to the computer.

Q. How to access individual grid variables(Cloumns) in ASP.Net GridView using C#

Ans- String name;

name=dSet.rows[0].coloum["Name"];

now you can use it to check for specific value like

if(name=="John")

{

//your code

}

Q. During linked list creation a=(node*)malloc(size of node) means?(C/C++)

Ans - Malloc() allocates memory dynamically i.e at run time only when it is required. It is used in creation of linked lists(dynamic) and ques(dynamic).in your statementnode * means - a ponter to the node of linklist/que etcsize of node - means eqaul to size of node i.e a address of variable+ value.

Q. What is URL.

Ans- The fullform of URL is Univarsal Resource Locator and its very common example is web site address http://www.hotmail.com/ (this is a URL). You can see that besides hotmail some other terms are here1. http - i.e Hyper Text Transmission Protoco:- This is a set of rules which is used to send and recive information on the Internet.2. www - i.e World Wide Web : a term used for millions of interconnected computer on the Internet3. com : i.e a domain which show the domain(group) of website.4. hotmail i.e a server/site name all four are pointed to a certain IP(Internet Protocol) address which uniquely indentify computers of Internet. This is someting like 192.144.145.98 and pointed by http://www.xyz.com/

Q. Write a C++ function with a 1Dinteger array as its input parameter, that returns both the largest and thesmallest number in that array. Also show the corresponding function call.

Ans -

void main()

{int ar[10],i;

clrscr();

void getminmax(int[]);

cout<<"\n Enter the elements";

for(i=1;i<=5;i++)

{

cin>>ar[i];

}

getminmax(ar);

getch();

}

void getminmax(int x[])

{

int i,j,k,t;for(i=0;i<=5;i++)

{

for(j=i+1;j<=5;j++)

{

if(x[i]>x[j])

{

t=x[i];x[i]=x[j];x[j]=t;

}

cout^^"\n Largest Number is"^^x[4];

cout^^"\n Smallest Number is"^^x[0];

}

Note: Use Extraction Operators instead of ^^ .

Q. Is it possible to work with C++ or similar programming languages on LINUX?

Ans. Yes, you can get inbuilt compilers and IDE' s for that C, C++, Java. You can also use Eclipse on Linux. Oracle is also available on Linux.

Q.'Column A' and 'column B' should be added in 'column C'. write a formula for entire column at a time , so that, you need not to write formula for every row. As we do format a entire column, is there any possibility to write formula for entire column? If you know, pl help me out.

Ans-Enter formula as an array. To do so select column C from top to bottom adjacent to A and B then type formula for whole range of A and B like =A1:A20+B1:B20 and then press Ctrl+ENTER, this adds c1=a1+b1, c2=a2+b2 ....................
