This sounds weird.
Can you try the application on another PC? That would tell you if your 'machine' permissions are broken.
What happens when you try load that XML file from a simple console application from your PC?
What is the filename you pass into it?
|
|
|
|
|
The error is caught on the following statement.
Doc.Load("c:\\vs\\Employees.xml");
If I try to run the code from a different .NET Windows Application on my PC it works fine. I did not setup that application, I inherited it from someone. Any new Windows Application that I setup the File IO Permissions does not work.
I really appreciate all you thoughts and suggestions. Thanks, Lisa

It sounds like your security permissions is messed up. You say someone else worked on that PC? Then it is likely the administrator didnt 'clean' the previous users permissions, and thus conflicting.

Is this Vista or Windows XP? Is the XML file in the root of c: ?
|
|
|
|
|
I'm using Windows XP. The file is not in the root of c:, however I have also tried to get the Selected Path from a FolderBrowserDialog and I have the same problem.
When I try this in the Windows Application that I inherited I do not have the problem; that's why I think it is an "environment" problem.
Thanks for your help, Lisa

Hey guys,
is it possible to change the color of individual rows in a DataDridView?
The data will be employees loaded into my application, the idea is to keep the row color of active employees white, make inactive - grey, make temporary - light green & make terminated - Red
any ideas where to start?
thanx

You could certainly do it via the 'CellFormatting' event by modifying the CellStyle.ForeColor and CellStyle.BackColor to whatever you desired. However, in that event you would need to change all the cells in the row to impact the entire row. There might be a way to do it automatically for the entire row as opposed to doing it cell-by-cell.

|

yeah cell by cell wouldn't be the best solution for this particular problem because each row has about 20 cells, and there will be a few 1000 rows at a time...

I need select from list containing product code and name but show only code in combo textbox.
Tried code below but dropdown list shows only code.
How to display both code AND name in selection list ?
using System.Collections.Generic;
using System.Windows.Forms;
class testForm : Form
{
testForm()
{
ComboBox cm = new ComboBox() { DisplayMember = "DisplayMember", ValueMember = "Code" };
List<Product> prodList = new List<Product>();
prodList.Add(new Product() { Code = "001", Name = "Wine", Cb = cm });
prodList.Add(new Product() { Code = "002", Name = "Beer", Cb = cm });
cm.DataSource = prodList;
cm.DataBindings.Add("SelectedValue", prodList, "Code");
Controls.Add(cm);
}
class Product
{
public ComboBox Cb;
public string Code { get; set; }
public string Name { get; set; }
public string DisplayMember
{
get
{
if (Cb.DroppedDown)
return Code + " " + Name;
else
return Code;
}
}
}
static void Main()
{
Application.Run(new testForm());
}
}

Thank you. I tried the code below but TextBox in combo shows name also.
How to show only code ?
using System.Collections.Generic;
using System.Windows.Forms;
class testForm : Form
{
testForm()
{
MultiComboBox cm = new MultiComboBox() ;
List<Product> prodList = new List<Product>();
prodList.Add(new Product() { Code = "001", Name = "Wine" });
prodList.Add(new Product() { Code = "002", Name = "Beer" });
cm.DataSource = prodList;
Controls.Add(cm);
}
class MultiComboBox : ComboBox
{
protected override void OnSelectedIndexChanged(System.EventArgs e)
{
Product product = (Product)Items[SelectedIndex];
SelectedItem = product.Code;
base.OnSelectedIndexChanged(e);
}
}
class Product
{
public string Code { get; set; }
public string Name { get; set; }
public override string ToString()
{
return Code + " " + Name;
}
}
static void Main()
{
Application.Run(new testForm());
}
}

When the code runs, the value of Cb.Dropped is always false. Stepping through.

Hi Vladimir Afanasyev,
I read your article .NET - Diving into System Programming.It is really intresting.You had mention some links in order to gain the Intial knowledge of System found all three of the articles to be very informative. I am working on a little project that requires listing all the drivers for a certain device (much like the device manager in windows does) but I have been unable to accomplish it. Can you point me to a resource that explains this or give a brief explanation of how you could do it ? You mentioned Some of msdn but it does not work
