have you tried the openFileDialog? It has the same view as the explorer window, with a dropdown to select views such as details/large icons etc.

The problem is the way you are handling the atomic number...it crashes because when you add an item it has its atomic number saved incorrectly: [CODE] if (m_theTable.ElementHasData(atomicNum - 1)) m_theTable.getElement(atomicNum).Print(); [/CODE] you are checking to see if 'atomicNum - 1' has data..then trying to print 'atomicNum'. A quick fix …

Hi, this is giving me a major headache and my boss wants the project wrapped up asap : / I have two views pulling data from several tables.

Rather than trying to iterate through the datagrid's rows, use the underlying datasource: [CODE] foreach (DataRow dr in ((DataTable)dataGrid1.DataSource).Rows) { if ((bool)dr[0]) { strFName = dr[1].ToString(); strLName = dr[2].ToString(); } } [/CODE]

It depends a great deal on the way the mobile's OS works, what access it grants to the camera etc. Considering the time frame youhave and what's riding on it, i'd steer clear of something that could hit a major issue and fall apart. Also, what if the camera is …

if you are using the DataGridView control then adatapost's code will work for you. However, you refered to a DataGrid; does this mean you are using the older DataGrid control or (like so many) did you drop the 'View'? :p If you are using a DataGrid then there is no …

The qustion seems a little ambiguous, i would check a few points with your lecturer. Primarily, 'Function' is a very ambiguous term: - in plain English it means a role or purpose for an object. - in a proceedural coding paradigm a 'Function' is a named code block which returns …

An excellent explaination DdoubleD :) And a great attitude from CyberPirate1. So many people paste the code, see that it works and move on. Its great to see someone stop to say "great, it works...but why does it work?". That attitude will serve you well as a coder :) Oh, …

You have started on the right track. Just break down the question. Often it helps to map out the required operations in pseudocode. Just focus on what you need to read in, process and output at this stage, then worry about the syntax afterwards. Your question already tells you everything …

One of the key benefits of type casting is that you know how the compiler will treat your variables. In the classic example: [CODE] var x = 5 var y = "37" var z = x + y [/CODE] Some compilers would treat both variables as strings and concatenate them …

You can check out [URL="http://msdn.microsoft.com/en-us/library/e2c9s1d7(VS.80).aspx"]this article[/URL] over at msdn. It outlines adding embedded resources to a project. Embedded resources are stored in a resource file rather than in their native format on the harddrive. They cannot be editted so this is only suitable for non-changing resources. Never used it myself …

Just a thought, but wouldnt it be better to have a seperate table for the additional fields in a zero-to-many relationship?

What values do you need to pass? Unless you right a custom event handler, the click event has a defined argument list.

Hi, I had a similar issue on a project. I overcame it by handling the datagridview's CellValidating and CellValidated events.

One way would be to limit the keys the user can press: [CODE] private void TextBox_KeyPress(object sender, KeyPressEventArgs e) { //only allow numbers and control keys if (!char.IsDigit(e.KeyChar) && !char.IsControl(e.KeyChar)) { e.Handled = true; } else if (char.IsControl(e.KeyChar)) { e.Handled = false; } else { //using this rather than TextBox.Text.Length …

You are adding a MosueHover event to the form. Try: [CODE] this.simpleButton1.MouseHover += new System.EventHandler(this.simpleButton1_MouseHover); [/CODE] if you want to change the back colour when the mouse is over the button you would be better to look at MouseEnter and MouseLeave so that you can change the colour back when …
