That's a big vague. Start by defining what you want this inventory system to do.

Hi, I'm new to asp.net and C# and am having problems understanding how to create custom events. I have looked at various sites and the most basic examples that I have been able to find are far too complicated for novices.
The tutorials that I have found all seem to suggest that, to create custom events, I need to write delegates and event handlers to start with but they are unclear and not specific.
Also, some of the code I have downloaded is dated and does not work with VS2005 and what happened to starting with the basics?! I.e. right from scratch.
Does anyone know any sites/links that might be useful to me.
Specifically, I want to be able to have to separate controls (ascx) linked to a parent control. Where one of the child contols contains a textBox and a button to submit text which will make the said text appear in the label of the other child control.
Any help truly appreciated,
Dave

Here's quite a good article on the subject (skip down to the step-by-step bit)

Me: Can you see the "up" arrow?
User:Errr...ummm....no.
Me: Can you see an arrow that points upwards?
User: Oh yes, I see it now!

Hi all,
I have Visio 2007 installed in my system. I would like to know how I can proceed in generating skeletal code from my Class diagrams designed in Visio.
Even I tried to do reverse engineering using Visio tool bar available in Visual studio 2005. But it resulted in blank Visio project.
Thanks in advance,

Hello!
When using a virtual listview, is it possible get new items added to the top of the listview instead of the bottom?
|
|
|
|
|
Hi!
Of course it is. With a virtual LV you handle the collection of items yourself.
If you insert new items into your element collection at the beginning, then these elements should appear at the top of the LV as well (if you create the ListViewItems according to the order of your element collection, which usually is the case).

But then I guess you mean I have to store all elements in some list (with the newest items first) and clear the listview every time I want to update it.
|
|
|
|
|
You don't have to clear the LV on every update. When the LV is in virtual mode, you're getting notified every time the LV needs to show a ListViewItem.
In this event handler you create a ListViewItem and return it to the LV.
In order to be able to know which element to create a ListViewItem for, you get an index into the list of elements. If you insert elements at the beginning of your list (and set the VirtualListSize accordingly), you'll be able to see the results immediately.

mav

Hi
I have spent the last few days surfing the net on WCF and on how to configure it, but I can't seem to find the correct solution.
I have made an application, that is used on internal lan (Client/Server). I would like to use the existing windows logon, and integrate with the local domain controller.
Additional I would like to have the option to enter an other windows logon, than the one the user is currently logged on with.
Security is not that big a concern, because all traffic is internal and the information is not very sensitive - but of cause it should not be ignored.
I would like to avoid having to setup SSL and manage certificates - It makes it harder to deploy, and if I have to purchase a certificate for every customer, it raises the price of the product.
How would you recommend setting up WCF in this scenario?
|
|
|
|
|
For a start, as it is internal, I would use NetTcpBinding. I'm not sure what else you want to know, but it's easy enough for you to get the windows user.
When it comes to using the user information, you can retrieve the users identity back like this:
WindowsIdentity id = ServiceSecurityContext.Current.WindowsIdentity; If you want to perform some impersionation with this value, you would just use:
using (id.Impersonate())
{
}

Hi Pete
Thank you for the speedy reply!
Is it really that simple? - I looked at message security configurations, that seemed far more complex.
E.g http://msdn2.microsoft.com/en-us/library/ms789011.aspx
Do you know how to specify the credentials on the client side, if entered manually?

Hi,
My code is
string connectionString = "Data Source=.\\SQLEXPRESS;AttachDbFilename=C:\\Documents and Settings\\venki\\My Documents\\Visual Studio 2005\\Projects\\CallCenterProject\\CallCenterProject\\new.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True";
SqlConnection conn = new SqlConnection();
conn.ConnectionString = connectionString;
SqlCommand cmd1 = new SqlCommand();
cmd1.Connection = conn;
cmd1.CommandText = "SELECT * FROM CustomerDetails WHERE OwnerId='" + label4.Text + "'";
cmd1.CommandType = CommandType.Text;
SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = cmd1;
DataSet DataSet2 = new DataSet();
da.Fill(DataSet2, "CustomerDetails");
ReportDocument rpt = new ReportDocument();
rpt.SetDataSource(DataSet2); crystalReportViewer2.ReportSource = rpt;

You have got to be freaking kidding me.
If you can't figure out what the problem is from that error message, you shouldn't be programming in the first place.

Your attitude stinks and it doesn't surprise me you received little help.
Plenty of hard feelings.

Whatever it is.... We got plenty of help from most of the subscribers of this site......Because its not our attitude but the perception is stinking...
Dont get surprised....By the way its better if you get to know that this is not the platform to demoralise others....
If you want to respond to for any messages just see whats the problem regarding the subject not the way it is portrayed.
We least bothered about the replies for this message!!!!!!

I have created service using WCF named pipe binding. I want to check whether any of my end point for the service with particular address is in use or not? How I can do it?
e.g. I have configured the endpoint using address "net.pipe//localhost/Test/ABC". Now if client tries to connect to the same end point again I want to catch this situation.
Can any one suggest the idea or direct me towards some documentation on it.
Thanks

All data in items of ListView is contained in ListView.Items collection.
private void Form1_Load(object sender, EventArgs e)
{
for (int i = 0; i < 100; i++) {
listView1.Items.Add(new ListViewItem(new string[] { "Product " + i.ToString(), i.ToString()}));
}
}
private void label1_Click(object sender, EventArgs e)
{
int sum = 0;
listBox1.Items.Clear();
foreach (ListViewItem item in listView1.Items) {
sum += int.Parse(item.SubItems[1].Text);
listBox1.Items.Add(item.Text + ": " + item.SubItems[1].Text);
}
label1.Text = "Sum: " + sum.ToString();
}
This code assumess that you have a listBox1, listView1, label1 and the listView1 has two columns : "Product Name" and "Price"

hi all,
I am trying to display a xml file in a datagridview.
i am using windows application with C#.
say for example, i have a xml file like this,
<xml version="1.0" encoding="UTF-8">
<maincategory>
<cat1>
<title>Category1</title>
<link>http://www.w3schools.com</link>
<description><img src="http://static.ibnlive.com/pix/sitepix/09_2007/flames_ramsetu90.jpg" >some description</description>

<description><img src="http://static.ibnlive.com/pix/sitepix/09_2007/rahul_gandhi_white90.jpg"
>some description</description>
</cat2>
</maincategory>
in the description i have a img tag containing a image from any site.
i have columns to display title,description.
i need to display the image along with the text in the same column description.

Hello...
I have a problem. I have a form, the form has 2 panels. Left and right. Left has 50% of form width, right also. I want to keep this 50% always. If someone resize the form, after resize, the size of left panel must be 50% of form and right 50% of form also. How to do that ?
Thanks...

Handle Resize event of a form
void Form_Resize(...)
{
panLeft.Width = this.Width / 2;
}
... assuming that:
panLeft.Dock = ...Left
panRight.Dock = ...Fill
