What, doesnt work?

Have you added your new label instance to the controls collection of youre form?

YourForm.Controls.Add(YourLabel);

~~P.S.: * I just cant find the question mark on that french keyboard Im working on!~~

All the best,

You're going to want to use a PlaceHolder.

protected PlaceHolder ph = new PlaceHolder();  //class scope
.
.
.

for(int i = 0; i < numberOfLabels; i++)
{
  Label l1 = new System.Web.UI.WebControls.Label();
  l1.ID = "Label" + i;
  l1.Text = strani.Rows[i][0].ToString();
  ph.Controls.Add(l1);
}

...You're probably not going to want to add it to the form.Controls default placeholder. ...It could screw your formatting up later on

that article pertains to winforms...and it's very convoluted. He was building an ASP.NET app. ..Using a PlaceHolder for his labels is much more straight forward.

loading authentication information from a config file

23-Jan-07 2:08

(I don't want to hijack the OP's thread, so this will be my last post in here unless OP requests my input) Actually, they are not the same techniques. In ASP.NET you can simply put a PlaceHolder control on the page and add dynamic content to it. You can set the PlaceHolder up so that it is dynamically sized, and none of your formatting is broken. The way you describe creating dynamic content using a PictureBox seems to be very, VERY 'hacky'

Hi everybody,
I'm currently developing an API that acts as a wrapper for an external pay-for-use web service. I have to authenticate our account information and the external provider returns an encoded key that I have to pass to every one of their service methods. To make it so that not just anyone can hook into the API and eat up the license, the decision was made that all of the account information had to be passed from the client to the API via a .config file. The thing that I'm concerned with is that the API is just exposed as a class library. Does anyone have have any ideas for best practices on allowing the client to pass configuration information to the authentication method in the API? The idea that I have was that the API shouldn't care and that the client side should worry about loading that info through their config file and just pass it to the interface method as strings. Does anybody see any conflicts with that? Anybody know of more elegant methods?

Get Desktop Layout

Greetings People Big Grin | :-D

.

I need to restore my desktop icons to a certain position.

My problem is that my program changes the resolution of the screen, now, when it closes, it returns the screen to the normal resolution, but by now the Icons on the desktop are all screwed up and out of place.

How can I restore them to their original place. I have searched for about 2 days and can't find anything that seems to do the trick and that I understand.

Thanks in advance.

You should NEVER do this. Your application is running on a shared system and you've written your app to NOT work and play nice with others. When the user hit's Alt-Tab to switch to another application, you've just limited them to the screen size your app imposed on the entire system. Do that on any of my machines and I'll uninstall your app and burn the install CD.

You can't. At least, I've never found a way to do it.

I wouldnt change the screen resolution on any normal app, but this is for a game I am attempting to write. Most games I have seen on my PC change the resolution and take up the whole screen.

If you have another sugestion how my app can take up the whole screen and remain the same visually then please let me know.

Thanks

That's because they use DirectX to do so. DirectX doesn't use the normal screen you see with your Desktop. In a Full Screen mode, it creates an entirely seperate drawing surface, kind of like an entirely new Desktop, complete with it's own video card parameters.

Basically, he's getting a handle to the desktop's listview control then using low level API messages to query the listview into a memory mapped area. Similarly, he's using messaging to the listview control to set the positions. Pretty tricky. Pretty scary.

There's several third party apps out there that save/restore icon positions. I'd see if one of those can be executed directly from your app, or contact the author of one of them for help.

The point of MDI is to be able to open multiple documents. You either want SDI (single document interface) or you need to test if the form is already open. Sort of defeats the purpose of MDI though.

How to change a homebrew screen saver's title?

Lumpie22-Jan-07 1:18

Hi there,

I have a farely simple question that I can't seem to find the answer
to.

I've got a C# Winforms application that after building results in an
executable. This executable is then renamed to an .scr file and used as
a Screen Saver.

How can I get this file to come up with a different name than the
filename in the dropdown list in Display Properties/Screen Saver? My
screensaver's filename is "screensaver.scr" and the dropdown shows
"screensaver", instead of a more friendly name "My Beautiful Screen
Saver".

I've searched everywhere but all I get is things that refer to a
StringTable, where you have to add a row with ID 1 and name "title" and
value "screensaver title". This should result in a different Title
being used in the dropdown mentioned before. However, I don't know how
to add this StringTable to my C# project.
When I open existing .scr files (that come with windows) in VS.Net
using the Resource Editor I see a StringTable that indeed contains this
ID 1 row, but when I open my own executable, I don't even have a
StringTable.

I hope someone can advise me on what to do.

Thanks in advance,

Mark

I have not a tested idea to point so I'll write two idea that i have based on similar situations. maybe they can help. Sorry if it is rubbish

1)You can prevent your application from loosing focus. So when win key is pressed your app must loose focus. If you deny that maybe it is a solution. I believe it is a wrong solution though

2)In previous years i had wirtten an app that hooked on every key and mouse move. Maybe if you create a hook handler and when win key is recognized, you can just consume the event so it wan't be passed to the explorer. But I believe this must be already the case for the exlorer so you is going to handle the message first I don't know.

Aain sorry. Just some ideas.
