How this can be do in asp.net???

Hi all
pls solve out this problem.
if user enter some data in text field.
then there will some complex eqn
input will be compute and then
accoring to that data
output will be produced.
but this will not be in simple text.
it will be in wave graph form.

IN A SIMPLE WAY

data enter in digit > digit compute in complex eqn like log e power x > ans generated > ans converted n grphs form > user get the graph .

You will need a third party control to produce graphs in ASP.net. Is that what you want?
Take a look at http://www.dotnetcharting.com/ it is free I think and may do what you need.

How do i input quadratics on a casio fx1500?


  • You have several memory locations you can use to store values in them. The memory locations are A,B,C,D, M, X, and Y. You use [SHIFT][RCL] and one of the variable names above. Example store 78 in C location: 78 [SHIFT] [RCL] [HYP]. To recall that value press [RCL] [HYP]

  • If you want to use the EQN (equation solving mode, press [MODE][5:EQN] then select the equation type . For example [3:aX^2+bX+c=0] will display a template wher you input the three coefficients.

  • You can also enter any type of equation and solve it with the SOLVE command. In that case you use the keyboard to enter the expression (see above how to enter variable name X). To type in the equal sign (=) use [ALPHA][ CALC]. Once the whole equation is typed in, press [SHIFT[ [SOLVE], and the calculator will prompt SOLVE for X? Confirm and press the main = sign. Press = again to get a second, a third root (if any)

How to do equations the papers that come with it doesn't explain it very well. Is there someplace where I can get a better explaination?


You can solve equations two ways: The EQN computational mode or the SOLVE application.
IN the EQN mode you can solve linear equations in one, two and three unknowns; the quadratic equation; and the cubic equation.
Enter the EQN mode by following the instructions on the following screen capture. Press 5:EQN
6_25_2011_1_06_32_pm.jpg
You have three types of equations.
6_25_2011_1_08_15_pm.jpg
Once you select the type of equations, a template is displayed where you enter the relevant coefficients.

6_25_2011_1_10_10_pm.jpg
Under each label (a, b, etc. ) enter a coefficient and press ENTER to move to the next. With a cubic equation, or a linear equation in 3 unknowns, you have to use the Right arrow to display the cells where you enter the value of d.
After you input all necessary coefficients press the = sign to get the solution.

To use the SOLVE feature, see the screen capture that follows. It comes from the Casio manual.

Solve a matrix of complex numbers using ti89 or any other ti calculator


Well, the equation is Ax=b and we want so solve for x
There are several ways of entering the data, but this is one way
Code: A=[15+35i 29+1i; 46+13i 62+3i]
b=[0;0]
x=A\b which has the trivial solution x=[0;0] (the ";" means "next row", a space next column.) To input a matrix use APPs then Data/Matrix Editor then New. Then change Data to Matrix. Put in the name such as "AA" in the variable field. Then enter row and column dimensions. Then edit as a spread sheet. Use F6(util) to delete a column or row. To manipulate matrices, exit the matrix application, then go to MATH then Matrix. Notice that J(RowOpps) is available. Good luck and thank you for using FixYa! We would sure appreciate a 4 "thumbs-up" rating for this answer. Happy holidays!

Text box restriction


I hope this helps and thanks for rating my effort...any other questions...shoot em to me....The Fang.

Restricting character input You can use the SetInputTextType command to restrict the characters that the user can enter in the text input dialog box. For example, suppose an application contains an input text field for users to provide a numeric value, such as their age, and that the input text field has the variable name ageVar. To ensure that the user enters only numeric values in the text input dialog box, you could add the following code to your application:
fscommand2("SetInputTextType", "ageVar", "Numeric");
When users open the input text dialog box, they can enter only numeric values in the text fields.
For more information, see SetInputTextType in the fscommand2 function entry in the Flash Lite 2.x ActionScript Language Reference.

What if i want user to only enter character in a textbox?


The field should be set as an ALPHA ONLY field! I am talking from the data base side of programming. In data bases you set a field as Alpha, Numeric, or Text. I am not sure if you will have the same options.

Validating in jsp


JavaScript Form Validation JavaScript can be used to validate input data in HTML forms before sending off the content to a server.
Form data that typically are checked by a JavaScript could be:
  • has the user left required fields empty?
  • has the user entered a valid e-mail address?
  • has the user entered a valid date?
  • has the user entered text in a numeric field?
Required Fields The function below checks if a required field has been left empty. If the required field is blank, an alert box alerts a message and the function returns false. If a value is entered, the function returns true (means that data is OK):
function validate_required(field,alerttxt)
{
with (field)
{
if (value==null||value=="")
{
alert(alerttxt);return false;
}
else
{
return true;
}
}
} The entire script, with the HTML form could look something like this:
<html>
<head>
<script type="text/javascript">
function validate_required(field,alerttxt)
{
with (field)
{
if (value==null||value=="")
{alert(alerttxt);return false;}
else {return true}
}
} function validate_form(thisform)
{
with (thisform)
{
if (validate_required(email,"Email must be filled out!")==false)
{email.focus();return false;}
}
}
</script>
</head> <body>
<form action="submitpage.htm"
onsubmit="return validate_form(this)"
method="post">
Email: <input type="text" name="email" size="30">
<input type="submit" value="Submit">
</form>
</body> </html>
E-mail Validation The function below checks if the content has the general syntax of an email.
This means that the input data must contain at least an @ sign and a dot (.). Also, the @ must not be the first character of the email address, and the last dot must at least be one character after the @ sign:
function validate_email(field,alerttxt)
{
with (field)
{
apos=value.indexOf("@");
dotpos=value.lastIndexOf(".");
if (apos<1||dotpos-apos<2)
{alert(alerttxt);return false;}
else {return true;}
}
} The entire script, with the HTML form could look something like this:
<html>
<head>
<script type="text/javascript">
function validate_email(field,alerttxt)
{
with (field)
{
apos=value.indexOf("@");
dotpos=value.lastIndexOf(".");
if (apos<1||dotpos-apos<2)
{alert(alerttxt);return false;}
else {return true;}
}
} function validate_form(thisform)
{
with (thisform)
{
if (validate_email(email,"Not a valid e-mail address!")==false)
{email.focus();return false;}
}
}
</script>
</head> <body>
<form action="submitpage.htm"
onsubmit="return validate_form(this);"
method="post">
Email: <input type="text" name="email" size="30">
<input type="submit" value="Submit">
</form>
</body> </html>

MS Access and ASP.net application


You probably need to be inserting the value of a text object (ie, a String) , not the object itself. In VB.NET, a String object is an actual, not unlike a Java String object. In "classic" VB, a String object isn't really handled by the interpreter as an object in the C# / Java sense, so it can be referred to directly without resolving the value via a method call. So attempting to insert an object reference into a database field from C# code will probably not work unless the database knows to call toSting() on the object, which I am 99.99999% sure it cannot (depends on the database-- in this case Access, and more particularly, what version you are using, and if there is any .NET framework interoperability).

Calling myString.toString() though returns a String object in C#, so using that is likely not going to work. What you may need to do is return a character array using the 'chars' and 'length' properties of the C# String object.

Finally, after all this, your problem could be a lot simpler: the value(s) you are trying to insert may not be right for the field-- check the length of the values being inserted, etc. Use .trim() to eliminate leading and trailing whitespace, for example. If you post your INSERT statement and an example of the data you are using, I may be able to tell you more. Also, you are in ASP.NET and data transfer from web containers to Access databases is notoriously bedeviled work.
