Hi Guy
I seen your code in above. i seen may be ur combobox haven't a selected value may be pass null value, so error will raise.
and second may be comboBox haven't records. so verify both condition after get comboBox1.SelectedItem.
when directly to use comboBox value we must do validations.that's give error free to us.
thanks
Cheers

AkmalSyed,
You could do it in a loop.
foreach (string email in emailCollection)
{
string header = "welcome to spammers are us!";
string body = "your message";
Email email = new Email();
email.Header = header;
email.Body = body;
email.EmailAddress = email;
email.Send();
}

It's rude to ask people to do your work for you. The poster gave you some useful advice. I suggest you use it to solve the problem yourself.

If you mean a web page, you can use Img[^] tag
If you are trying to use display it in a form, use PictureBox[^] control

private Bitmap MyImage ;
public void ShowMyImage(String fileToDisplay, int xSize, int ySize)

// Sets up an image object to be displayed.
if (MyImage != null)

MyImage.Dispose();
}
// Stretches the image to fit the pictureBox.
pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage ;
MyImage = new Bitmap(fileToDisplay); HOW TO GIVE HERE FILE PATH WHICH EXIST IN MY PROJECT

Just use the relative path for fileToDisplay. Example: "cool.bmp" or "..\\images\\cool.bmp".

RajeevKumarSharma,
You have to ways. Use Graphics to do it, or use a PictureBox. I am guessing your pretty new to C# so id go with PictureBox.
Regards,
Gareth.

This should do what you want
Bitmap pic = new Bitmap(fname);
xsize = pic.Width;
ysize = pic.Height;
// Adjust the position of the picture box
pictureBox1.Location = new System.Drawing.Point((0, 0);
// Adjust the size of the picture box
pictureBox1.Size = new System.Drawing.Size(xsize, ysize);
// Display the image
pictureBox1.Image = pic;

I have a dropdownlist that contains items ,
each item points to the each tablename of a fixed database.
I simply added a blank CrystalReport1 without adding any table, any logon informatio while creating Crystal Report.
and also added CrystalReportViewer Control.
private void Page_Load(object sender, System.EventArgs e)
{
if(dropdownlist1.Selectedvalue=="Table1")
{
SqlConnection con=new SqlConnection();
con.ConnectionString="Server=.;uid=sa;pwd=abc;database=db";
con.Open();
SqlDataAdapter da = new SqlDataAdapter("select * from table1",con);
DataSet ds=new DataSet();
da.Fill(ds);
//ds.Tables.Add();
CrystalReport1 report2=new CrystalReport1();
//report2.SetDatabaseLogon("userid","pwd");
report2.SetDataSource(ds);
//CrystalReportViewer1.DisplayGroupTree = false;
CrystalReportViewer1.ReportSource =report2;
CrystalReportViewer1.RefreshReport();
}
else if(dropdownlist1.Selectedvalue=="Table2")
{
SqlConnection con=new SqlConnection();
con.ConnectionString="Server=.;uid=sa;pwd=abc;database=db";
con.Open();
SqlDataAdapter da = new SqlDataAdapter("select * from table2",con);
DataSet ds=new DataSet();
da.Fill(ds);
//ds.Tables.Add();
CrystalReport1 report2=new CrystalReport1();
//report2.SetDatabaseLogon("userid","pwd");
report2.SetDataSource(ds);
//CrystalReportViewer1.DisplayGroupTree = false;
CrystalReportViewer1.ReportSource =report2;
CrystalReportViewer1.RefreshReport();
}
}
and so on.........
=====================================================
crystal Reprt is coming without data and columns of the table,(Ensuring the table contains data),i think the dataset is not attached ,
How can i attach database and dataset dynamically
Please solve this.....

Anyone used NDoc, it does not compile help when the C# 2.0 templates are in the code, producing null reference exception. Anyone handled this without removing C# templates?

Don't use NDoc. Microsoft has released SandCastle which takes care of this neatly. At the moment SandCastle is entirely command line driven, but you can find a GUI SandCastle manager here on CodeProject (clickety)[^].
|

|
|
Why with NDoc. I've found its GUI superb. Command line is much tricky to use. Will see the link if I can just with a single mouse click produce help file.

NDoc's GUI is superb - and it's the basis of the link that I put above. If it had continued to be developed fully in .NET 2, I'd have no hesitation recommending it - unfortunately it hasn't.
|
|
|
|
|
Could not run it successfully, see the message board of the link you sent me.
If you can help with the problems. It can not be compiled also, just 4 projects out of 6 as I remember in that solution under VS2008.

|

Have you downloaded the latest version from CodePlex here[^]?
|
|
|
|
|
Yes. It said you need latest sandcastle also to work? It failed to compile entire solution anyway, but GUI was compiled.
Why can not it work with latest sandcastle from microsoft downloads?
I want to run codeproject or codeplex GUI with microsoft downloaded sandcastle.
BTW. NDoc GUI looks more authentic

I don't think you can set the DPI of your printer, it's simply a property of the printer. Instead, you need to scale your image to be the right size to print for that DPI at the size you want.

Hi everybody!
I have a DataTable which has 3 column. First column has type int, the second double, and the third is the product of the first and the second column.
How can i set the third column that the values in it have only 2 decimals after the decimal point?
DataTable dt = new DataTable("test_table");
dt.Columns.Add("column1",typeof(int));
dt.Columns.Add("column2",typeof(double));
dt.Columns.Add("column3",typeof(string),"column1*column2");
dt.Rows.Add(new object[] { 1, 5 });
dt.Rows.Add(new object[] { 2, 4,994 });
dt.Rows.Add(new object[] { 3, 6 });
dataGridView1.Columns.Clear();
dataGridView1.AutoGenerateColumns = false;
dataGridView1.DataSource = dt;
dataGridView1.Columns.Add(new DataGridViewTextBoxColumn());
dataGridView1.Columns[0].DataPropertyName = "column1";
dataGridView1.Columns.Add(new DataGridViewTextBoxColumn());
dataGridView1.Columns[1].DataPropertyName = "column2";
dataGridView1.Columns.Add(new DataGridViewTextBoxColumn());
dataGridView1.Columns[2].DataPropertyName = "column3";
Ex: in the second row the third column expression is 2*4,994 = 9,988 but i want that only 9,98 be the value.
I need this because the user can add rows to the datagridview and i want that also in the added rows to function this.
Thanks for your help!

Hi Noemi Katinka!
Use Math functions. It will round up the values upto given decimal point.
Like Math.Round(ProductAnswer,2)
Hope this will help you.
