{
DatabaseQueries dbs = new DatabaseQueries();//im calling class
dbs.GetPerson(Convert.ToInt32(textBox1.Text));//gaiving value
Person ps = new Person();
// Person settheperosn;
textBox2.Text =ps.name ;
textBox3.Text = ps.sex;

}

http://www.codeproject.com/Tips/767067/RDLC-Report-Grouping-with-Page-Break-Table-Header

run your program as administrator,
or use sqlite it quite fast ....

thank you so much dear, that is what i was trying to do ,

sorry

thanks bro for your answer,
but here i have to put specific number of rows,
i know there is way i can add new rows to table but !!!!!

thanks man thats so true,but this was just for trying..

okay thanks ,sorry if its not clear.
i wanna have column in datagridview that is buttons type and that
buttons.text = some text from datagridview rows
or more easyly i wanna convert column[a] from text to buttns
thanks

change this
smtpHost.UseDefaultCredentials = true;

thanks for your note sir,
that was just for explain
i tried my data and relation in sql before applay on visualstuido

you wanna delete selected value from datagridview

try to set break page ...
you can check it

hello , i didn't used with access i used it with sql but i think its same..
put this cryRpt.Load("set your crystal path here\CrystalReport1.rpt");and in crystal report there is some change you have to made like embedded or new or from path
that decide take crystal report from where...
and if my question is not clear plz let me know :)

your question is bit unclear but you can create view in
sql server but just adding view and select which column you want
that called join ,
and if you want do that in c# you have to create query and load to view

but what if have many richtexbox this will be only in richtexbox2..
i want richbox be like
richtext={return is=60}// here is available
rechtext={the connectin is not available}//here when roundtirp=0
rechtext={return is=87}// when connection comeback
many thanks again

sorry for all that , but let me tell what exactly what i want to do is show result on richtextbox and that works fine at this point everything is Oky but what i can't do is show this message {the connectin is not available} when total time is =0...
:) sorry man

thanks that make sense but
as you see i wanna put some string between those brace and get that string form elsewhere
thanks

however in here it doesn't do anything but if put something like
{else if(totaltime.ToString()=="0")
{
messagebox.show("you losing connectin");//how i can get this text
}
this will show messagebox every time totaltime became 0
thank

im not so sure about your question do you want to use database to store those data?
if you want save data in some place and the sql is good database to use and easy to use, if this is u question
and here is link you can check

the error is {The type 'System.ComponentModel.Component' is defined in an assembly that is not referenced. You must add a reference to assembly 'System, Version=2.0.0.0}

thank you so much , i hope i didn't toke of your time sorry if i :(
but i have searched for that before and i got some error so i thought you may give me a new ways..

ConnectionStrings["Data"].tostring

im not sure about your question and what type of databse but you may use this if u use sql database
sqlcommand cmd=new sqlcommand("insert into table2 values (select id from table2 where name =@name)",conn)
cmd.parametrs.addwithvalue("@name",combobox.text);
cmd.executenonquery;

when it won't work is there any error appears? and change configuration to any cpu..

you mean i set time to repeat this instruction

no i couldn't find that library and im such stuck here,,,mr,afzaal can i programmatically set target platform version?

mr.afzaal ahmad i have searched a lot and couldn't find solution :( there is not much guidance about mobile windows,,,,, so
i hope so so much i can find solution here

thank you for your replay mr,Afzaal Ahmad Zeeshan
can you tell me which reference?
because added references i think issue is with platform {with windows mobile when i got this error i change target platform to x86 the error would disappear} but in here i use windows mobile 6.5 there is no target platform....
