Hi,
Here is the architecture.

There is a business layer set up as a peoject with a class i.e. class1

Class1 has two functions. One to populate a hashtable with 10 data and the other to count the data in the hashtable.

There is a windows service i.e. WindowsService1 that calls the populate function in the business layer.
The count on the hashtable is 10

There is another windows service i.e. windowsService2 which call the same businesslayer to count the hashtable. The couont on the hashtable is 0
Do you know why this is the case and is there a solution to this please?
Thanks

He's saying that each webservice will have an instance of hte class in their own process space. If you start Solitaire twice on your PC, the cards in one game won't change what the cards are in another. That's what you're trying to do, to make two programs share data.

Yes, I have now come to that conclusion. And that is exactly what I am trying to do. i.e. applications to shhare the hashtables from a common dll.
1)
What is the alternative and how can I do this please?
2)
Would you say it is better if I save the data into files on the disk and share it that way?
4)
Someone said it is possible to share the hashtable data via a webservice. What do you think?

How to show a "Process with ..." entry in the File-Explorer context menu

Hi,

I want to allow the user to right click on one or more files in the Explorer and then select a custom context menu entry like "Process with myProgram" (beside "Open", "SendTo" etc.).

I found out that it is quite easy to add such an entry for a Folder. To do this you just have to set up a new SZ entry in the System-Registry under "HKEY_CLASSES_ROOT -> Folder -> shell -> Process with myProgram -> Command" which contains the path to the program as value.

But that does not work with special file types. Does anybody have an idea how to do that?

Thanks in advance!

Active Directory access

Hi,

I have a small windows application that connects to the local directory and retrieves the list of users. Then, it is possible to display the data of the user by clicking on a button. I use LDAP://DomainName to connect and things "seem" to be working fine. I manage to get the different data of the user I select (name, country, address, email, phone etc...) however I am having a problem with the "memberof" property. For some users, I am able to retrieve the list of groups he belongs to but for other users the property returns an empty collection. I am using the following piece of code:

<br />
 SearchResultCollection src = ds.FindAll();<br />
 SearchResult sr = src[0]; // I am filtering per username so only one match possible<br />
 ResultPropertyValueCollection memberOf = sr.Properties["memberOf"]; // this sometimes returns zero items<br />
 ResultPropertyValueCollection givenName = sr.Properties["givenName"];<br />
 ResultPropertyValueCollection lastName = sr.Properties["sn"];<br />
 ResultPropertyValueCollection email = sr.Properties["mail"];<br />
 ResultPropertyValueCollection address = sr.Properties["homePostalAddress"];<br />
 ResultPropertyValueCollection zip = sr.Properties["postalCode"];<br />
 ResultPropertyValueCollection country = sr.Properties["co"];<br />
 ResultPropertyValueCollection title = sr.Properties["title"];<br />
 ResultPropertyValueCollection city = sr.Properties["l"];<br />
 ResultPropertyValueCollection state = sr.Properties["st"];<br />
 ResultPropertyValueCollection phone = sr.Properties["telephoneNumber"];<br />
 ResultPropertyValueCollection otherPhone = sr.Properties["otherTelephone"];<br />
 ResultPropertyValueCollection fax = sr.Properties["facsimileTelephoneNumber"];<br />

Then I filter the memberof collection like this:

<br />
 foreach (object role in memberOf)<br />
            {<br />
                string[] roleItems = role.ToString().Split(',');<br />
                foreach (string temp in roleItems)<br />
                {<br />
                    int i = temp.IndexOf("CN=");<br />
                    if (i >= 0) // found string<br />
                    {<br />
                        listGroups.Items.Add(temp.Substring(3));<br />
                    }<br />
                }<br />
            }<br />

This will give me the group name. I have tried displaying the whole "role" string without parsing, I thought maybe my parsing was not complete, but I didn't get anything either.

I am new in Active Directory stuff and I have no idea if there is another way to do things.

Any help would be greatly appreciated.

Web, Dynamically Gridview creating Eventhandling

Greetings,

On a web page I have create several Gridviews dynamically as a result of a stored procedure.
The gridviews are building well and filled with data.
I also created the select and edit button on every gridview.
I also created several eventhandlers, delegates etc for these gridviews.

But what button's) I press on the grid, I never get into the subroutines I created for these purposes.
Do I also need to create something (a connection) for the dynamically created buttons and the events?

Thanks for every advice

Code:

//GridViewSelectEventHandler Delegate; Represents the method that handles the SelectedIndexChanging event of a GridView control.

//Delegates END ====================

Hi fellows, You may have seen printing option, 2 sheets per page on Microsoft Word. Well, if not then these are the steps for what i am talking about are: File--->Print--->Properties. The thing that matters to me is that I have found the exact same options and layout for Print 2 Sheets Per page on Acrobat Reader software. Does microsoft provide those functionality or is it also built by Acrobat. I want to know if I can provide the smiliar options for my small application would be nice. I would appreciated your answers.

Help with binding combo box and datarow column

Matthew Cuba23-Mar-07 3:59

23-Mar-07 3:59

Hello,

I've got a combobox that needs to provide the following choices:

choice1
choice2
choice3

I've also got a dataRow with some columns, one of them is called "choice".

I want to do two things, and I believe it is possible to do but I don't quite know how to set this up. First, I want to make the "choice" column update to the selection made in the combobox. Additionally, I want to update the combobox to display the current value in the "choice" column, as it might have changed via another source - assume that there are two displays both providing the same controls and both pointing at the same dataRow. I'm wanting to keep this combobox "in sync" with the choice currently in the dataRow. How do I do this?

Thanks,
Matt

For the datarow to change when you select something in the combobox, it's easy, just add some code to the ComboBox.SelectedIndexChanged event.

table.rows[x][y].value = comboBox1.Value

but to do it the other way around, you either have to use events too (f.e. DataTable.RowChanged...) or you can use a timer that checks the datasource for change and updates the combobox.

Visual Studio can't evaluate this, can you?

public object moo<br />
        {<br />
__get { return moo; }<br />
__set { moo = value; }<br />
}

I suppouse the datarow is in a datatable..
if you have a datatable then you can bind it using BindingSource.
set the DataSource of the BindingSource object to the table object.
then set the DataSource of the ComboBox object to the BindingSource object and the DataMember and DisplayMember to proper column names from the table.

<br />
someBindingSource = new BindingSource();<br />
<br />
someBindingSource.DataMember = "tableName"; // if the table is in a dataset<br />
someBindingSource.DataSource = someDataTable; // or DataSet<br />
<br />
someComboBox.DataBindings.Add(new System.Windows.Forms.Binding("SelectedValue", someBindingSource, "Column2name", true));<br />
someComboBox.DataSource = someBindingSource;<br />
someComboBox.DisplayMember = "Column1name";<br />
someComboBox.ValueMember = "Column2name";<br />
someComboBox.DropDownStyle = System.Windows.Forms.ComboBoxStyle.DropDownList;<br />

Listview control flckering in .NET 2.0

pliu_200023-Mar-07 3:27

pliu_2000

23-Mar-07 3:27

Hi,

I have an urgent issue with an activeX control I have written in .NET 1.1 based on the listview. When I run the control on .NET 2.0 there is very bad flickering whereas on .NET 1.1 there isn't any. I am updating the listview asynchronously using BeginUpdate/EndUpdate along with a separate class that gets the data in a separate thread. The listview is then updated using the BeginInvoke approach.

I have dissassembled the .NET 2.0 listview and found that for some reason on every item add it executes a control.invalidate() hence forcing a repaint. Therefore, this leads me to believe that there is no way to avoid the flickering.

Does anyone have any information on this as I am surprised that the listview could be released with this problem?

Anyway, this also leads me to believe that to resolve my problem is to force the application to use .NET 1.1. However, my control is hosted as an activeX object in IE. Therefore, I cannot just use the IExpore.Exe.config file to force IE to use of .NET 1.1 framework for obvious reasons. Therefore, my second question is.

Is it possible to configure an assembly to use a specific .NET framework version?

My third question is.

If I am constrained with using an executable (having my own app domain) so that I can use my own config file to force the .NET framework version. Is it possible to host my activeX.exe in IE withing the <object> tags as I am now with my activeX control?

I hope you understand my post and hope someone out there can help.

Many thanks in advance
