[RESOLVED] PLZ help meeeeeeeeeee

when we do this system generate error
Operator '+' cannot be applied to operands of type 'object' and 'int'

if (dReader.Read())
{
return dReader[0] + 1;
}
And
when we do this system generate error
Cannot implicitly convert type 'string' to 'bool'

if (strTableName = "")
{
dAdapter.Fill(dSet);
}

this one.

VB Code:

return (int)dReader[0] + 1;

and for your second problem please try to explain in details so that it is easy to identify. :bigyello:

The solution to the second one is :

Code:

---

if (strTableName == "")
{
dAdapter.Fill(dSet);
}

---

double equal sign for comparison .

In C# it would be something like :

return int.Parse(dReader[0]) + 1;

if (dReader.Read())
{
return dReader[0] + 1;
}

fret showed you howto . Did that work for you ???

our purpose is auto generate Id we pick max id in data reader and add one in max id

we do this but system generate error
The best overloaded method match for 'int.Parse(string)' has some invalid arguments
Argument '1': cannot convert from 'object' to 'string'

if (dReader.Read())
{
return int.Parse(dReader[0])+ 1;
}
