Re: How do you display separator bars in a StatusBar?

If you want seperators, why not add them as a border on the controls, you can specify different widths for the border, so put 10,0 on the middle one to get 10 on each side. Otherwise, I expect you'd need to specify widths on the seperator itself, and specify a width of 10 on your column definition.

WPF is a PITA, it's way too hard to get stuff to appear at the size you asked for.

Borders on the controls are a last resort possibility, but my question was, why don't the Separator elements show up? I shouldn't have to specify a width on them, as their constructor should specify a default width. In no other code I've ever seen do you have to specify a width for a Separator.

But I experimented by setting a width and was shocked to discover that the Separator in a StatusBar is a horizontal line, not a vertical line as one should expect. One should expect that, right? I suppose a horizontal line will work, but I wonder who's brilliant idea it was at Microsoft to make a Separator a horizontal line in a WPF StatusBar? Isn't that totally nonstandard? You'd expect horizontal lines only between items arranged vertically, like the separators between menu items.

I tried an explicit width on the column definition and it didn't work, so went back to Width="Auto". When I specified a width on the separator itself, that's when I discovered the very strange thing that the Microsoft developer has done, in making separators horizontal lines in status bars instead of vertical lines. This almost seems like a bug to me. I should just put a vertical bar in there.

It isn't. It's orientation is based on the ItemsControl it is used as an item in.

You didn't use them as ItemsControl items so you got the default horizontal
orientation.

See my other replies for two ways you can use the separators in a more correct fashion.

I took the Separator elements out. Those horizontal lines just look like a kludge.

Why would you take the separator elements out if you want separators?

I gave you two working examples - one that you can totally customize
the style of the separators, and another that uses the default style.

I took them out before I saw your examples. After I saw your second example, I put them back in. Now they look great. Thanks for your attention.

*Edit*
With your Separators wrapped in StatusBarItem, they default to a horizontal orientation, so
you'd need to give your separators a vertically oriented style, otherwise you can't see them...

Shouldn't that style then be a template, so it gets reused ? :P

OK, so a seperator is invisible without a style ? I've never used one, so I had no idea about that.

To use the default Separator style, remove the StatusBarItem
wrappers from the Separators:

           Height="23"

How to find the temparary drives created

Okay, now we're talking. Good answer. Thanks, Mark. Looks good. I just make them invisible when the middle TextBlock is empty. Sure was a lot of screwing around for a lousy pair of Separator elements.

Hi,

I am working on a WPF application. In this I need to find the temporary drives created i.e., like drives created when some mobile or pen drive are created. From this Temporary drive created I need to get the image files.

If any one have any idea to get the names or path of the temparory drives created please reply me.

Thanks in advance.

This is not a WPF question.

Take a look at DriveInfo class[^], especially DriveInfo.GetDrives[^]. You can check for the Drive having DriveType as DriveType.Removable.

A WPF browser application runs in the browser ? I would assume that the issue is the application being sandboxed then.

How to connect a XPAP application to the Northwind database

20-Jun-09 13:09

I'm sorry if I misunderstood you at first, someone else has been posting about a browser application in WPF, and asking the same thing for days. I am trying to help you here, there's no need to delete your posts, or feel unwelcome. I am sorry for the misunderstanding, I do suspect that you're saying the app is running inside your browser, and that sandboxing is why you can't access a local DB, but you can probably access a network one. Have you had any luck with that avenue ?

CBenac20-Jun-09 15:34

Re: How to connect a XPAP application to the Northwind database

20-Jun-09 15:34

There is a sample application that uses the DataGrid (from the WPF Toolkit) and displays the customers table from the NorthWind database. It runs fine if it is created as an EXE which is the original intention of the author. However, since I need the application to run in the browser, I recreate the same project as a XPAP but the browser displays the bellow error message (snipet) from the "More information" link. It appears to be a connection issue with the database. I'm using Windows authentication mode.

Re: How to connect a XPAP application to the Northwind database

21-Jun-09 0:39

OK - well, if you're in the browser, then I assume you're serving your app over the web. You're going to need a connection string that connects to a remote machine, not one that relies on Windows security, because the browser is sandboxed from the rest of the machine. It's basically the security in the browser that is hitting you. Have you tried using a username/password to connect to the DB ?

CBenac21-Jun-09 12:58

Re: How to connect a XPAP application to the Northwind database

21-Jun-09 12:58

I changed from Windows to SQL Server authentication and logged as User: sa and the password, but it didn't make any difference. I'll look into this remote machine you mentioned. But any additional sugestion is welcomed. It is surprise to me the few online documentation regarding WPF.
Thanks so far for your input.
