i tried it with two ways.
given below:

std::string str=
"attribute vec4 Position;\n"
"attribute vec2 TexCoord;\n"
"varying vec2 vTexCoord;\n"
"uniform float ScrollOffset;\n"
"uniform float Depth;\n"
"void main()\n"
"{\n"
" vTexCoord = TexCoord;\n"
" vTexCoord.s = vTexCoord.s * 0.125 + ScrollOffset;\n"
" gl_Position = Position;\n"
" gl_Position.z = Depth;\n"
"}\n";

const char *test= str.c_str();
char * writable = new char[str.size() + 1];
std::copy(str.begin(), str.end(), writable);
writable[str.size()] = '\0';

both test and writable character pointer stored truncated string of the real str string.
that is:
Result is given below
test= writable= "attribute vec4 Position;
attribute vec2 TexCoord;
varying vec2 vTexCoord;
uniform float ScrollOffset;
uniform float Depth;
void main()
{
vTexCoord = TexCoord;
vTexCoord.s = vTexCoord.s * 0.125 + ScrollOffset;
gl_Position = Position;
gl_Posi "

not whole data is assigned to test and writable (char pointer) variables. this time i did it with little simple method but the result is same

but unfortunately it works fine for 32 bit system.. thats bugging me.. if it had some misinterpreting character, it should had failed in 32 bit compile too.

I tried other methods too but the result is same.. thank you for your consideration.

no idea... i am not being able to figure out why only part of the total string is assigned.

Thank you for your support

Thank you for your help

thank you for your help I will try to solve the problem

how can i check if there is a client request ?

Actually my idea was to sort a paged gridview. for an example my table ins tblForum with topicName and NumberofComment as an attribute. and with 26 records in the table and i have pagged the gridview to show only 5 records in one page.
suppose my first page displays topic name from a to e and there are records of topicname from a to z in the table. now if i click topicName the sorting should occur in e to a not in the form z to v in the first page. In summary i want to sort only the content of the page that is displayed. I hope i made my problem more clear. thank you for your reply

ya this is a good answer...

ya inline messaging could be better than messagebox

yes in case of the albert comment...yes sometime the user have to know what was wrong with their input and providing the example of the valid inputs or inputs that are not acceptable should be shown to the user for the better understanding of the program by the user. thank u

yes thanks

yes it must depend on the situation... if a text box should be filled with numeric data then i prefer to not giving right for user to enter alphabet or other character.. i added my question for the justification of my solution..
thanks

will it be a good programming practice?

i know what it does.. it is used for making better looks of the interface design... but i was unable how to install it in vs2008. now i know ho to install it

thank you for your help

thank u for your help.

thanks i never thought to make change in program.cs thank u very much now i will try it

sorry i didn't understand u. i have never tried #if...i tried it but it produced more problems

frmEntrySecretKey is my first form..

i tried doing in this way but it also didn;t helped

public partial class frmEntrySecretKey : Form
{
public frmEntrySecretKey()
{
InitializeComponent();
initialevent();

}
public void initialevent()
{
string sk = BllLoginHelper.checkSecretKeys();
if (sk == null)
{
frmLogin frmlogin = new frmLogin();
frmlogin.Show();
this.Hide();
}
else
{
MessageBox.Show("there is A KEY");
}

}

how can we program the barcode for different key?

ya maybe i am not a pro..just learning so can't properly explain sorry... but i got my answer

thanks pal....u solved my big problem...thanks alot...

thank you for your help i will work out on it...if u have some refrence database can u send it to me in amsainju@gmail.com or arpan_s@hotmail.com..
thank u again

public static void insertNewStudent(string name,string clas,string section )
{
int STATUS;
SqlConnection con = GetConnection.getcon();
string qry = "insert into tbl_student(stud_name,stud_class,stud_section) values( @name,@clas,@section)";

SqlCommand cmd = new SqlCommand(qry, con);
cmd.Parameters.AddWithValue("@name", name);
cmd.Parameters.AddWithValue("@clas", clas);
cmd.Parameters.AddWithValue("@section", section);
STATUS= cmd.ExecuteNonQuery();
if (con.State == ConnectionState.Open)
{
con.Close();
}
}
public static string getId()
{
string stud_id=null;
SqlConnection con = GetConnection.getcon();
string qry = "select @@IDENTITY";
SqlCommand cmd = new SqlCommand(qry, con);
SqlDataReader sdr = cmd.ExecuteReader();
while (sdr.Read())
{
stud_id = sdr. ; //??????????????
break;
}
if (con.State == ConnectionState.Open)
{
con.Close();

}
return stud_id;

}

am i doing it right?? i can't figure out how i can retrive the data from sdr..

am i doing it right??
the error was introduced in

hey i did as u said... but the code show only one problem..
in the following line

reportViewer1.LocalReport.ReportPath = Server.MapPath(rptName);

the error is
the name Server does not exists in current context...

i am using these class libraries

+5

good ans john
+5

my too +5

if (dgvSearch.Rows.Count > 0)
{
dgvSearch.Rows.Clear();
dgvSearch.Rows.Add(15);
}

i had forgetten to use dgvSearch.Rows.Add(15); in my code
the error was shown because dgvSearch.Rows.Clear() clears or say deletes all the empty rows that i used for a better design...
thank u all for your help

ya not working in windows application :(

it didn't worked :(

there is no such property such as datbind in c#...

hey sorry john i was just testing what these voting does.

i tried dgvSearch.Clear() too but it didn't helped...i am still nowhere.

i tried to use that but when i executed the program it showed this problem


Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

in this part of the code:

dgvSearch.Rows[j].Cells[0].Value =table.Rows[j].ItemArray[0].ToString();

so any ideas???

i heard that databind is not necessory in c# it is only used in asp.net..... and i have seen the property named databind in c#..so what should i do

i reached to a good link surfing through them thanks for ur help

hi,
i didn't get it...
how this could disable the selection of the cell if the cell is null

the code didn't showed any problem in it..i rechecked my steps with the given steps in the tutorial but i did exactly what stated in the tutorial....
though i use c# but the code was given in vb so i used converter to change the vb code to c#
this is the website i used for the conversion

http://www.developerfusion.com/tools/convert/vb-to-csharp/

In the code,

private void ExecuteSql(string DatabaseName, string Sql)
{
System.Data.SqlClient.SqlCommand Command = new System.Data.SqlClient.SqlCommand(Sql, masterConnection);

// Initialize the connection, open it, and set it to the "master" database
masterConnection.ConnectionString = My.Settings.masterConnectionString;
Command.Connection.Open();
Command.Connection.ChangeDatabase(DatabaseName);
try {
Command.ExecuteNonQuery();
} finally {
// Closing the connection should be done in a Finally block
Command.Connection.Close();
}
}


but this line didn't worked i think due to the framework version compatible issues...
masterConnection.ConnectionString = My.Settings.masterConnectionString;
....
it specified the error as "the name 'My' is not in the context"
so i changed the code with
masterConnection.ConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings["dbCustomAction.Properties.Settings.masterConnectionString"].ToString();
adding a refrence of system.Configuration
so this code didn't showed any problem...
now i don't know where specifically my problem resides...
can you now help me with this??

thanks for the suggestion..i will check it out again

hey i visited
http://msdn.microsoft.com/en-us/library/49b92ztk%28v=VS.90%29.aspx#Y1075
for my solution i did as stated in the page with little modification in the code to manange the problem that occur with different version of .net framework...
at the end the whole code didn't show any error but when i executed the output the following error occured in the middle of the execution
Error 1001.Object reference not set to an instance of an object

if you like to see the code i did i can send you in your email...

do you have any example can you send it to me in amsainju@gmail.com
thanks for your support

thank u...for the help :-)

thanks for the links i will check it out...thank u
