Enabling Multiple forms in ASP.NET

The ASP.NET Control/PostBack Architecture is excellent for most Web . However, there are a few limitations that can sometimes be quite significant.One of the most fundamental problems has been the restriction to one server Form. This is very annoying for me i tried different methods but none of them worked, finally i tried with the panels and worked perfectly. I'm sharing you steps for enabling multiple forms in a single page. This article is a review of solution to the problems:

Use Panels inside the form tags....

Sample Code

< id="Form1" method="post" runat="server">
< id="panel1" runat="server">
< id="Textbox2" runat="server">Form1
< runat="server" id="Button1" name="Button1" text="Click to see Form2">

< id="panel2" runat="server" visible="false">
< id="TextBox1" runat="server">Form2
< runat="server" id="Button2" name="Button2" text="Click to see Form1">

Just try it and give feedbacks...

Programming with Parallel Port LPT

Now i'm working on a project to create a C/C++ software for communicating to the Parallel Port [LPT1]. Here i'm giving you the source code part which can be used for Parallel Port Programming. I'm sure that this may help you in some ways for your projects. Later i found that there is a library file named ParaPin which it easy to write C code under Linux that controls individual pins on a PC parallel port. but i didnt use that coz my whole system must be changed in order to do a small program. But Parapin is really helpful file for developers.

Source Code

#define port 0x378 //data port 8pins 2,3,4,5,6,7,8,9
#define status 0x379 //status 5pins 11,10,12,13,15
#define control 0x37A //control 4pins 17,16,14,1

void main()
long int value;
int ch;
cout<<"** AD9851 Programming with LPT1 **";
cout<<"\n1. Send values to LPT";
cout<<"\n2. Set all data pins HIGH";
cout<<"\n3. Set all data pins LOW";
cout<<"\n4. Reset";
cout<<"\n5. Exit";
cout<<"\n Choose your entry :";
case 1:
for(int i=0;i<5;i++)
cout<<"\nEnter W"<<<"=";>
outport(control,0001); //clock high
cout<<"Setting Word Clock High!!!\n";
outport(control,0010); //freq update high
cout<<"Setting Frequency Update as HIGH !!!";
cout<<"Word Entered Successfully....";
goto go;

case 2:
cout<<"\n Setting all data pins to high...";
cout<<"\nPress any key to continue...";
goto go;

case 3:
cout<<"\n Setting all data pins to low...";
cout<<"\nPress any key to continue...";

goto go;

case 4:
cout<<"\nResetting Complete...";
cout<<"\nPress any key to continue...";
goto go;

case 5: exit(0); break;
default : cout<<"\nWrong entry...";


void checkstatus()

unsigned int far *ptradr; /* Pointer to location of Port Addresses */
unsigned int address; /* Address of Port */
int a;

ptradr=(unsigned int far *)0x00000408;

for (a = 0; a <>
address = *ptradr;
if (address == 0)
printf("No port found for LPT%d \n",a+1);
printf("Address assigned to LPT%d is %Xh\n",a+1,address);


Internet Activity Monitor Wizard

This software is developed for interet users. Now-a-days

there is a small problem for dialup users(usually) ie. if we
have connected the system to internet for downloading
in the night time and if the mobile battery power is running
lower, the mobile will be powered off and the net wil be
disconnected and the system will be in the ON state till
furthe user interactions, this will charge a lot of power.
So i developed this software to counter this, it will monitor
the system and will power off automatically whenever
the net connection is terminated.
