Re: Identifying the value is negative or positive in float number

Hi,

i have the below code in my page.

protected string ConvertPercent(object number)
{
if (number == DBNull.Value)
return "-";
else
if (number == float.Negative)
return "0";
else
return "1";
};

i want the "0" to be return incase NUMBER having negative (exp: -1.236)
i want the "1" to be return incase NUMBER having positive (exp: 1.236)

Please help me......i dont know the syntax for this....thxxx

Is this code working?

If no try following code
this is not a proper way to identify number is negative or positive but it will work.

if(number.ToString().Contains("-"))
return 0;
else
return 1;

best regard

I assume you are taking the **** here? Convert a number to a string, checking if the string starts with a 'minus' symbol to determine if it is negative or not?

You need to cast number from object type to float before doing checking

i did that before.......but was encounter error........

Operator '<' cannot be applied to operands of type 'object' and 'int'

Brooo.....after implement ur code into my page.....got some confusion happen with the result....c below....

Grp1 +0.0071
Grp2 0.0001
Grp3 +0.0047
Grp4 +0.0041
Grp5 +0.0038
Grp6 0.0001
Grp7 +0.0005

for the data 0.0005 it has + sign.......but for data 0.0001 dont have....any idea???

Below is the code.

protected string ConvertRM(object number)
{
if (number == DBNull.Value)
return "-";
else
if (number.ToString().Contains("-"))
return String.Format("{0:F4}", number);
else
return String.Format("+{0:F4}", number);
}

This all looks very bizarre. Please post a sample of the actual data returned from teh database. Don't format it, just post it here as it is stored in the table. You will get a far better solution than the one you are using at the moment.

You have to cast the object type to float.

protected string ConvertRM(object number)
{
   float FNumber = (float)number;
   if ( FNumber < 0 )
      return "0"; //It's a negative value
   else
      return "1"; //It's a positive value
}

ok it seems i found the solution.

protected string ConvertRM(object number)
{
if (number == DBNull.Value)
return "-";
else
if (number.ToString().StartsWith("-"))
return String.Format("{0:F4}", number);
else
return String.Format("+{0:F4}", number);
}

i replace Contains("-") to StartsWith("-")....it looks working....

thxxx 4 d help......

Hi to all,

i have developed one web application with login page. Everything is working well on standalone PC but while on network if somebody logs in with a particular username & password and someone else tries to login on another PC then it automatically logs in with the username of person who is already logged in.

i have used cookies for my login page. Can anybody please tell what is the mistake?

i think the problem is different than cookie as cookies are stored at client side by the browser.
Are you using any static variables or something like that in login page
Again how are you using the cookies in your application ?

Thanks and Regards

I think that there is some problem while creating the application object and session object.

Application object is created for the application(only one) while session objects are created for ecah user separately, that keeps track of the user.

Use a Gridview/DataGrid , put a TemplateColumn and add a TextBox there. Bind Gridview/DataGrid with data from the table. It will give you 3 TextBoxes(depends on no of rows returned). Cool | :cool:
