i want to use smtp.host = "localhost" smtp.port = 25 and want that in mail."From" portion user should enter email id no matter it is gamil or yahoo ?

i tried this but i have to provide my gmail id and password then mail is sent from my gmail account but it makes gmail account necessary to all users bout what if somee one want to send mail from yahoo or any other domai??

Content moved to question.

S is the text of label and it is M but still not enetring in this block

what is the benifit of using item Comand event here how it is different from my approach
??

i want that if answer type is "M" radiobuttonlist should be shown or if it is "C" checkboxlist should appear!!

i tried this thing
cmd2.Parameters.AddWithValue("@ctext",TextBox6.Text);
cmd2.Parameters.AddWithValue("@ctext", TextBox7.Text);
cmd2.Parameters.AddWithValue("@ctext", TextBox8.Text);
cmd2.Parameters.AddWithValue("@ctext", TextBox9.Text);
but gets the following error
The variable name '@ctext' has already been declared. Variable names must be unique within a query batch or stored procedure
i had tried this before posting the Question and now again geting same error .

cmd2 = new SqlCommand("Insert into Choices(Choicetext,Questionid) Values (@ctext,@qid)");
cmd2.Parameters.AddWithValue("@ctext",TextBox6.Text);
cmd2.Parameters.AddWithValue("@qid",qid);
i am doing with above code. actually i do not know how to get text of each textbox as in above case you see that only one option will be saved i.e text of TextBox6 and what about remaining four textboxes??

thnks for guiding me but i have a seprate table options(optionid,optiontext,Questionid) how i can insert in this table

<asp:DataList ID="DataList1" runat="server" DataSourceID="SqlDataSource1">
<itemtemplate>

<asp:Label ID="QuestiontextLabel" runat="server"
Text='<%# Eval("Questiontext") %>' />
<br />

<asp:Label ID="Label1" runat="server"
Text='<%# Eval("QuestionID") %>' Visible="false" />
<br />
<asp:Label ID="Label3" runat="server"
Text='<%# Eval("Answertype") %>' />
<br />
<asp:RadioButtonList ID="RadioButtonList1" runat="server"
DataSourceID="SqlDataSource1" DataTextField="Choicetext"
DataValueField="Choicetext">

this is my datalist

i have one table Survey(Surveyid,title,Description) and Second is Question(Questionid,Text,Surveyid)i want than when i add detail of survey and question both should be entered . i successfully inserts the first record get the value using Socpe Identity but while inserting in second i get error
.

thanks to all friends plz answer another question of mine that as in www.fluidsurvey.com and in google form we can select answer type of our choice and textboxes , radio buttons etc.appears dynamicly according to answer type selected so can this thing can be done using asp.net and javascript???

the prblm i m getting is this that when i select survey all question are shown at one place i want to show one question then its options and then second questions... not getting the required format??

i have currently used sql data source .. and data grid to show questions and options but it is not working the way i want . kindly share a tutorial plz..

i want to make some controls visible and other invisible depending on the checkbox being selected.kindly can you share some tutorial in which shows how to make some portion of a form visible on the basis of which checkbox is selected.

i want to get four edge points(x,y) axis of corner of one image and then want to translate the sacnned image in a way that edge points of second image become same as of first one so that second image becomes same as first one.

i have two image first is original and second one is scanned copy of first the scanned copy gets rotated and enlarged after scann so i want transformation of second image to become same as first(original) img.

so i should have pictureBox1.Image!=null before that line??

i have tried and my code is given below


private void button1_Click(object sender, EventArgs e)
{

try
{
OpenFileDialog open = new OpenFileDialog();
open.Filter = "Image Files(*.jpg; *.jpeg; *.gif; *.bmp)|*.jpg; *.jpeg; *.gif; *.bmp";
if (open.ShowDialog() == DialogResult.OK)
{
pictureBox1.Image = new Bitmap(open.FileName);
myBitmap = new Bitmap(pictureBox1.Image);


}

}
catch (Exception)
{

throw new ApplicationException("Failed loading");
}
}

private void button2_Click(object sender, EventArgs e)
{
while (pictureBox1.Image != null)
{
pictureBox1.Image = ResizeBitmap(myBitmap, 333, 444);
}
}

public static Bitmap ResizeBitmap(Bitmap sourceBMP, int width, int height)
{
Bitmap result = new Bitmap(width, height);



using (Graphics g = Graphics.FromImage(result))
g.DrawImage(sourceBMP, 0, 0, width, height);

return result;
}

private void button3_Click(object sender, EventArgs e)
{
if (pictureBox1.Image != null)
{
SaveFileDialog saveFileDialog = new SaveFileDialog();


saveFileDialog.Filter = "Bitmap (*.bmp)|*.bmp";
saveFileDialog.FilterIndex = 1;
saveFileDialog.RestoreDirectory = true;


if (DialogResult.OK == saveFileDialog.ShowDialog())
{
pictureBox1.Image.Save(saveFileDialog.FileName);
}
}
else
MessageBox.Show("No images are currently open.", "Alert");


}

}
but i am geeting "outof memory exception" at line : using (Graphics g = Graphics.FromImage(result))
g.DrawImage(sourceBMP, 0, 0, width, height);
plese help me to avoid this exception???

i have drawn circles on image using graphics.drawellipse() method and after saving image i have printed and scanned it but the scanned image is elarged so i want it to be of original dimensions.....

can you share a complete code please!!!!!!!!!!

gr.DrawImage(img, new Rectangle(0, 0, width, height));
herw "img" is which image. mean either it is new one or refernce of the image on which it is to be drawn

yup that is what i want to do but how to get average of colors in c#??

so far i have designed an answer sheet like the one used for filling mcqs answers. i have drawn circles using Drawellipse() method. and i have stored the points which are residing iside the circles now i want to get color of all these pixels and then to get average color of all these points.

cl[0] = myBitmap.GetPixel(array_X[0], array_Y[21]);
cl[1] = myBitmap.GetPixel(array_X[1], array_Y[22]);
cl[2] = myBitmap.GetPixel(array_X[2], array_Y[23]);
cl[3] = myBitmap.GetPixel(array_X[3], array_Y[24]);
now i eant to get average color of these points i.e cl[x] = Average(cl[0],cl[1],cl[3])

is it neccesrry to convert image into grayscale???

as we do average like avg(45,35,40) then avg will be 40 in the same way i want to know average of colors how to do this in c#??

Dear i am OK with GETpIXEL.it is an winform actually now i want to get the color which is more occuring in these pixels i.e if a circle contains 10 points out of which 7 are white and 3 are black then i want a method which should take these points clor and result should be that color is white as majority points are of white color???

yes but i am not having any idea about how to get position of circles inside image with respect to x y coordinates!!!!!!
