Hi - I am trying to get my application to automatically select the item that was last added to my list box but am not sure how to get this done. My code so far is as below. Please bear in mind that I am using Windows Presentation Foundation.
private void btnLoad_Click(object sender, RoutedEventArgs e)
{
//Declare an instance of the open file dialog...
OpenFileDialog dlg = new OpenFileDialog();
dlg.ShowDialog();
string fileName = dlg.FileName;
lstBxList.Items.Add(fileName);
//Once the file has been loaded, select it...
????????
}
|
|
|
|
|
dlg.ShowDialog();
string fileName = dlg.FileName;
lstBxList.Items.Add(fileName);
lstBxList.SelectedIndex = lstBxList.Items.Count -1;
should do the trick.

Try this
private void button1_Click(object sender, EventArgs e)
{
OpenFileDialog dlg = new OpenFileDialog();
dlg.ShowDialog();
string fileName = dlg.FileName;
lstBxList.Items.Add(fileName);
lstBxList.SelectedIndex = -1;
lstBxList.SelectedIndex = lstBxList.Items.Count - 1;
}

Hi Peeps
I created a desktop App and published it with click once, I have a mdf with the published files and I am saving that mdf to a location on my c drive.
I tested the app on 2 different pc's and it works fine but on another pc I get an error, the pc where the error is on does not have SQL installed...
here is my error please help,
Error : a network-related or instance-specific error occured while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.(provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
Thanks

You can't just access mdf file. You need to install MSSQL Server on the machine you're installing application or provide access to the server somewhere in the LAN/WAN.
Or if you don't use advanced SQL Server features you can try SQL Server Compact Edition (3.5 or 4.0). This is light version of the SQL Server. It has some limitations, but for some uses it is enough. It can be provided to the end user as 3 or 4 dll libraries.

Thanks for the reply, I understand that but I'm using the prerequisites in the publish properties and I've selected SQL Server Compact 3.5 and SQL Server 2005 Express Edition, isnt that suppose to sort that out for me?

|

Aaaa. It should. You didn't mention it in first post  Maybe firewall is blocking access to the server?

Sorry  , but its not going to a server, let me explain in detail...
after you installed the app from the network you login on the program then a mdf is saved to that users's pc, so the program reads from that mdf file on that users's c drive

This is starting to be interesting 
The error message you get looks as if the application tried to connect to SQL Server (not using express edition).
Maybe your app.config has some error (for example you don't set provider or something like this).

No beleive me everything is in there, appconfig etc.
This is one of those things I cant get my head around
here is my appconfig : <add name="ConnectionString1" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=C:\Folder\Databse\File.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient" />

You're using SQL Server. ./SQLEXPRESS in DataSource indicates instance of SQL Server. Check the firewall settings and if the SQL service is up. And if the instance of the SQL Server on the machine is named SQLEXPRESS.

Well, you have the basics of a design there. You need to flesh it out a bit.

What have you tried so far?

Real programmers don't work for ruppess.

I disagree.
I work to pay for games.
I like Zelda.
So I work to pay to get Zelda.
The currency in Zelda games is usually rupees.
Ergo I do work for rupees.

Ummm... oookaaayyy... what does that have to do with ruppesses?

Hi,
I am wondering, is there any technique available to copy an object to another object when the objects are of different class but the signature of these classes are same (100% identical) ? For example, if I have
class A
{
public string Name;
public string EmailAddress;
}
and
class B
{
public string Name;
public string EmailAddress;
}
Now, in my code, I have a::A, b::B.
I want to copy all property values from b to a, but I have to do it manually by iterating all properties of b to a one by one like this.
a.Name = b.Name;
a.EmailAddress = b.EmailAddress;
I wish if there were any techniq to automate this task!! I know about Copy/Cloning techniques where the objects are from same class. But as you see my objects are from different class. If my class were so simply like this, I would not have worried, but my class A and B has around 50 properties which is hard to maintain. So, I would appreciate any idea.
Regards.

1) you could inherit from the class that has all your properties then still would be able to use reflection or cloning or etc.
2) in each class have the same sub class which will have the same properties so then pass from one to the other either by using reflection or cloning or etc.
3) one way is to use an interface. implement each property that would exist in each class and use reflection to pass the information by going after the interface in both classes.
