Re: Problem in recalling value with array Christian Graus6-Nov-05 11:58 Christian Graus 6-Nov-05 11:58  FoodPrice[MealList.SelectedIndex] is probably what you're looking for, although I'd have done it with a hashtable to be safe. Or perhaps FoodBox.SelectedValue ? A combobox can store name/value pairs, but you'd know if you'd done that, I guess. Christian Graus - Microsoft MVP - C++ Label doesn&#180;t show up on form naglbitur6-Nov-05 8:35 naglbitur 6-Nov-05 8:35  Hi. I put some Label controls on a form and then put Text into them. I also wanted to put a random number into some labels on the same form. So I do this: Random r = new Random(); label6.Text = r.Next(88).ToString(); label6.Location = new Point(90,60); this.Controls.Add(label6); This is what I did to the other Labels that I want on my form except I did not put a random number into them. The problem is that the label (label6) doesn´t show up on the form. Why is that? What am I missing? What do I need to do so that the label shows up on the form containing a random number? Thanks, FJ Re: Label doesn&amp;#180;t show up on form Christian Graus6-Nov-05 11:59 Christian Graus 6-Nov-05 11:59  You don't need to do anything different, so that is not where the problem is. Can you set the location before adding it to the form ? I'd have done those two in the other order. Christian Graus - Microsoft MVP - C++ Speed up?

Lju2 Com+ Problem webhay6-Nov-05 4:15 webhay 6-Nov-05 4:15  Hello All, I made a Com+ component connect over network to insert , update and delete from the Sql serve in the same network. but i got error means that no connectivity between the server and client. I need to know what is the default ports and portocols that the Com+ user it over the network? Thanks Hay Re: Com+ Problem Heath Stewart6-Nov-05 6:21 Heath Stewart 6-Nov-05 6:21  A search in the Microsoft Knowledge Base for COM+ ports to open for firewalls[^] yields what you want. The first result - How to configure RTP dynamic port allocation to work with firewalls[^] is probably what you want. The linked article How to configure a firewall for domains and trusts[^] might also be helpful to solve potential authentication issues. You could also define either a specific unused port for the COM+ component or a static range for all components and open those on the firewall, but the former would be more secure. Don't forget to open ports on the client Also keep in mind authentication. Once you've solves connection problems make sure that you've set up the appropriate authentication and authorization for your component using the Component Services MMC snap-in. Much of that can be configured using the appropriate attributes on your COM+ service, too. This posting is provided "AS IS" with no warranties, and confers no rights.

What I want to to do is only add those folders to the Treeviw that are of the correct type which means I need to query the type. I expected to be able to do something like:- if (currentFolder.GetTypeOfFolder = olMailFolder) { AddChild(...) } but I can't find any reference to a folder type that I might be able to use in this way. Anyone with any bright ideas? Cheers, Goose Re: C# TreeView and Outlook Folders _Goose6-Nov-05 4:19 _Goose 6-Nov-05 4:19  Hold that thought, just answered it myself! For those interested, the answer is:- if (mF.DefaultItemType == Outlook.OlItemType.olMailItem) { AddChild(...) } Transparent Custom Controls Johnny Hooyberghs6-Nov-05 2:30 Johnny Hooyberghs 6-Nov-05 2:30  How do you paint a user control with transparent background?

As regards the component sliding etc it is all ok. However, during design mode the V.S. doesn't let me place controls inside the panel. It places them on top of the panel, not into it. Can any one help out on this. Best Regards Re: Custom Controls Johnny Hooyberghs6-Nov-05 2:28 Johnny Hooyberghs 6-Nov-05 2:28  Try deriving your custom control class from System.Windows.Forms.Panel instead of System.Windows.Forms.UserControl Hope this is what you are looking for...

I wanna have something like this, except it doesn't return the whole row but just the Address: <br /> // Declare a data row to hold the selected customer's record.<br /> DataRow drSelectedCustomer;<br /> drSelectedCustomer = <br /> dsNorthwind1.Customers.FindByCustomerID(SelectedCustomerID); thank you again Gerri Datagrid Binding to an Object wgroves5-Nov-05 20:13 wgroves 5-Nov-05 20:13  I'm really struggling trying to bind a Datagrid to a collection of objects. I understand that for each public property of the objects in the collection, a column will be displayed. But I don't want to display a column for all of the public properties, just some of them. And I also want to add columns to the datagrid for things like an image that is associated with one of the properties. How do you hide columns when binding to objects? How do you add columns to a datagrid when it is bound to a collection of objects? Any help would be greatly appreciated! Thanks Warwick "I hear they've even got the internet on Computers now." - Homer Simpson Re: Datagrid Binding to an Object J4amieC6-Nov-05 0:31 J4amieC 6-Nov-05 0:31  If you databind a datagrid to a list of objects, it will create a column for each property as you said. However, if you first create a DataGridTableStyle and add to it the DataGridColumnStyle objects that you want then only those columns will be shown. This can be done directly in the designer. Re: Datagrid Binding to an Object wgroves6-Nov-05 10:13 wgroves 6-Nov-05 10:13  Thanks! I've just had a look at TableStyles/ColumnStyles and will try it today. Cheers Warwick "I hear they've even got the internet on Computers now." - Homer Simpson Re: Datagrid Binding to an Object n10sive10-Nov-05 12:15 n10sive 10-Nov-05 12:15  Take a look at ITypedList. Adding it to your collection allows you to create property descriptors. The Datagrid will respect this list. This is more "class friendly" to implementers and they won't have to use table styles to get rid of the unfriendly stuff.
