That says your trying to store a byte but your data is a byte array

Maybe you can use the ObdbType.Image datatype.

cmd.Parameters.Add("@pic", OdbcType.Image);

Also, MemoryStream can be directly converted to byte array.
byte[] blob = msI.ToArray()

Thanks have done that as well
no change to outcome

string query;
query ="insert into testimage (id_image,pic) values('t', @pic)";
msI.Position=0;
//BinaryReader oReader = new BinaryReader(msI);
System.Data.Odbc.OdbcCommand  cmd = new System.Data.Odbc.OdbcCommand(query,OdbcCon );
//cmd.Parameters.AddWithValue("@pic",oReader.ReadBytes((int)msI.Length));
cmd.Parameters.Add("@pic",System.Data.Odbc.OdbcType.Image);
//cmd.Parameters["@pic"].Value = oReader.ReadBytes((int)msI.Length);
cmd.Parameters["@pic"].Value = msI.ToArray();
cmd.Prepare();
cmd.ExecuteNonQuery();
MessageBox.Show("Image Added");

thanks again for your help so far

Hi,

maybe msI is a stream you just filled with some data and forgot to reposition to the beginning of the data?

try adding msI.Position=0;

Hi,

why is your subject line starting with "MySQL" while your code uses ODBC?

the solution to your problem is in this page[^], read all of it!

PS: don't disable statements by commenting them out, it makes your source unreadable.
the purpose of comments is to clarify things, not obfuscate them.

Hello, I have a problem on the table layout panel control. I wanted to create a program that on run time I could set the table layout panel's number of rows and columns. My Problem is that the spaces of each boxes on the table are not evenly distributed. How do I make it evenly distributed?

This code worked fine for columns, it can also be slightly modifed to fit for rows:

tableLayoutPanel1.ColumnStyles.Clear();
int numOfColumns = 4;
tableLayoutPanel1.ColumnCount = numOfColumns;
for (int i = 0; i < numOfColumns ; i++ )
{
	ColumnStyle cStyle = new ColumnStyle();
	cStyle.SizeType = SizeType.Percent;
	cStyle.Width = 100 / numOfColumns;
	tableLayoutPanel1.ColumnStyles.Add(cStyle);
}

Hello, I have a DataGridView on a Windows Form , it has 3 columns, one of them is a CheckboxColumn, the other two columns are set to be automatically sortable.
The problem is that when I sort one of the sortable columns, the selected checkboxes in the CheckBox column are lost..
How can I keep the checked checkboxes checked after performing a sort on another column.

If I populate a listview with somethinglike:

foreach (DebtorDataSet.DebtorListRow row in debtorDataSet.DebtorList.Rows)
{
  ListViewItem item = listView.Items.Add(row.Code);
  item.SubItems.Add(name);
  item.SubItems.Add(row.IsPostcodeNull() ? "" : row.Postcode);
  item.SubItems.Add(row.IsTelephoneNull() ? "" : row.Telephone);
}

How can I set the backcolor of a row to red if row.Telephone is null please?

Well, The method ListViewItem.SubItems.Add() can take a simple string to create a subitem, but it also can take a ListViewItem.ListViewSubItem object to do the same thing.
So, you can create ListViewItem.ListViewSubItem subitem, set its BackColor property to whatever you want, and then add it to the SubItems collection of your ListViewItem

ListViewItem.ListViewSubItem it1 = new ListViewItem.ListViewSubItem();
it1.BackColor = Color.Red;
item.SubItems.Add(it1);

hello...
my form has a static image like a photo of 100 computers. then my application pings the systems and if the destination is reachable then the corresponding computer must have a green light else a red one.
the problem is that the image has to be the same and only a part of it has to be changed,
i am thinking of doing this with the help of graphics in c# and would be pleased if any other methods work.... thank you .

Add it to IIS as an application.

Post an error-message here if you get stuck, or a specific question. Chances that someone will write a walkthrough are slim.

Because it's a real server-product, whereas XP isn't.

Checklist;
- Did you create a new application in IIS?
- Did you check the permissions?
- Did you install all required components?

Questions;
- Does the server work when you put a plain HTML file in the folder? Does it get served correctly to the browser?
- Can you run a simple aspx-file that only displays the current time, without too much login-logic and stuff?

How about Application_Start in global.asax?

Despite everything, the person most likely to be fooling you next is yourself.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
