Set the ShowEditingIcon property to False. I think that's what you are looking for.

Editing glyph IS NOT the black arrow, showing the row selected! The question is still actual. And I think the solution is to draw in row header. But what exactly? I'm sure somebody had already fixed this issue.

The one that indicates which row is selected? I haven't yet found a way.

And DataGridViews are for talentless hacks anyway, so I don't bother.

Have you another decision besides DataGridView to show information in table-style?

I solved the problem. As my CellPainting has already been overriden, I added such construction to clear the arrow:
using (Brush backColorBrush = new SolidBrush(e.CellStyle.BackColor))
{
e.Graphics.FillRectangle(backColorBrush, e.CellBounds.X+1, e.CellBounds.Y+1, 20,40);
}

How to create ".eml" file using desktop application in .net to use it to send E-mail?

9-Jul-08 4:49

There's not much you can do apart from drawing the X-button yourself and react to mouse clicks in the proper area. For this you need to derive your own control from TabPage.
See this articles how to do some owner drawing on a page control:

How you create a file, is up to you. What is an eml file ? I have no idea.

You need to know how to send a file via email ? There's tons of articles online that cover this.

hashtable within a hashtable

Just looked it up in Thunderbird by saving an e-mail in this format. It's basically just the mail header as received from the mail server (from, to, subject, mime, content-type, return-path) and the message body.

I don't see how this can be used to send e-mail.

Hi, i got a hashtable within a hashtable. How do i retrive the property from the inner hashtable

I got this orderTable which store a Order object.

Inside my Order object, i have a Hashtable itemList as a attributes. The itemList will store a product object which have the property ModelNumber

foreach (Order order in orderTable.Values)
{
    if (order.ItemList.ContainsKey(Convert.ToString(p.ModelNumber)))
    {
        uint modelNum = ((Product)order.ItemList[p.ModelNumber]).ModelNumber;
        string cellValue = Convert.ToString(p.ModelNumber);
        if (cellValue == Convert.ToString(modelNum))
        {
            dataGridProduct.Rows[currentRow].Cells["colSelect"].Value = true;
        }
    }
}

this is what i do, but i get

Object reference not set to an instance of an object.

on this line

uint modelNum = ((Product)order.ItemList[p.ModelNumber]).ModelNumber;

This, by definition, returns a hashtable, not a Product. That's what you said, right ? That returns a hash table, so you need to pull the value out of that hash table. I am surprised you don't get an invalid cast exception.

i cast a (Product) infront already and i just do a .ModelNumber

issint this pulling out the value? i tried many ways but cant seems to work. Probably you could help me with it?

Christian Graus9-Jul-08 4:14

The other response makes sense. I think what you said is wrong, I don't think you have a hashtable of hashtables. I think you're using a bad key, or a key to a value that was stored as null.

I guess ItemList is already the inner hashtable which will, when accessing the indexer, return a Product

I guess so, I was just looking for the code that does what he asked about - accesses an object that is two hashes deep.

This may have several reasons:

- order is null
- the returned Product may be null: You are checking ContainsKey with a string (Convert.ToString(p.ModelNumber)), but pass some other data type to the hashtable key (p.ModelNumber)

Try this:

foreach (Order order in orderTable.Values)
{
    string modelNumberStr = Convert.ToString(p.ModelNumber);
    if (order != null && order.ItemList.ContainsKey(modelNumberStr))
    {
        uint modelNum = ((Product)order.ItemList[modelNumberStr]).ModelNumber;
        string cellValue = modelNumberStr;
        if (cellValue == Convert.ToString(modelNum))
        {
            dataGridProduct.Rows[currentRow].Cells["colSelect"].Value = true;
        }
    }
}

Windows Service accessing DMZ resources

Apologies if this is not in the correct forum, but hopefully someone can help with the below issue:

I have a C# Windows Service (.Net 2.0) that is to be installed on a collection of web servers in the DMZ. The Windows Service implements a FileSystemWatcher to check for changes to a set of specific CSV files held on a network share, and will copy locally any updated files before importing these to a local SQL database.

The distribution server that will hold the updated CSV files is also in the DMZ.

The problem:
How can I set up the Windows Service / distribution server so that the service can access the network share securely? It seems that no matter how I set the service up i.e. running as LocalSystem, LocalService, NetworkService or a specific user account (can only be a local account as no access to AD in the DMZ) I get System.UnauthorisedAccessException's occuring when attempting to set up the FileSystemWatcher.

Any help would be greatly appreciated.

Clean code is the key to happiness.
