If the account your code is running under isn't recognized by the server, you MUST supply a username and password to it in order for it to let you into the Share. You simply have no way around this.
You can find an example of logging into a remote server here[^].
If you don't have appropriate credentials recognized by the remote server, you're outta luck until you get an account that IS recognized.

How do I get the user's current wallpaper bitmap? (keeping in mind that the user might have set the wallpaper with either the desktop properties control panel applet, or with the SetParametersInfo method in user32.dll) Is there an API call that returns a bitmap or a handle that I can use to create a Bitmap object?
I'm not wanting to change or alter the wallpaper, I'm wanting to display it as a Bitmap object on a Form.

Microsoft.Win32 is used for accessing the registry, while System.Runtime.InteropServices is used for accessing the unmanaged user32.dll.
Next comes the preparation of the unmanaged function SystemParametersInfo() - this should be located at the top of the class definition:
[DllImport("user32.dll", CharSet = CharSet.Auto)]<br />
<br />
static extern int SystemParametersInfo(int uAction, int uParam, string lpvParam, int fuWinIni);
First thing is to retrieve the current desktop wallpaper, and to do that we don't need to use a function, but simply read a value in the Windows registry. Let's create the method for that:
private string GetCurrentWallpaper()<br />
<br />
{<br />
<br />
<br />
RegistryKey rkWallPaper = Registry.CurrentUser.OpenSubKey("Control Panel\\Desktop", false);<br />
<br />
string WallpaperPath = rkWallPaper.GetValue("WallPaper").ToString();<br />
<br />
rkWallPaper.Close();<br />
<br />
<br />
return WallpaperPath;<br />
<br />
}
Next comes the definition of the method that actually sets the wallpaper, Additional for you . And it's only a few lines of code:
private void SetWallpaper(string WallpaperLocation, int WallpaperStyle, int TileWallpaper)
{
// Sets the actual wallpaper
SystemParametersInfo(20, 0, WallpaperLocation, 0x01 | 0x02);
// Set the wallpaper style to streched (can be changed to tile, center, maintain aspect ratio, etc.
RegistryKey rkWallPaper = Registry.CurrentUser.OpenSubKey("Control Panel\\Desktop", true);
// Sets the wallpaper style
rkWallPaper.SetValue("WallpaperStyle", WallpaperStyle);
// Whether or not this wallpaper will be displayed as a tile
rkWallPaper.SetValue("TileWallpaper", TileWallpaper);
rkWallPaper.Close();
}

I only needed to get the wallpaper. I didn't know that the registry's value was updated that well (I just looked on mine and it's correct, despite me circumventing the control panel applet), so I'm good to go. I already know how to set the wallpaper (and I have a handy app available for free download from my blog). Thank you for the info! It helps me greatly!

System.Media just contain classes for Sound Player but not 4 vido files. If u know how to play video files , can u give me a short codes

You should look into WPF it has some fantastic ability to handle media files. Try this article

Greetings
I am trying to make threads that run loops to be at the exact same step as the other threads. For example an output to the application could be the following:
Thread 1 = iteration 1
Thread 2 = iteration 1
Thread 3 = iteration 1
Thread 4 = iteration 1
Thread 1 = iteration 2
Thread 2 = iteration 2
Thread 3 = iteration 2
Thread 4 = iteration 2
and not
Thread 1 = iteration 3
Thread 2 = iteration 2
Thread 3 = iteration 1
Thread 4 = iteration 1
Thread 1 = iteration 4
Thread 2 = iteration 3
Thread 3 = iteration 2
Thread 4 = iteration 1
I am thinking of an implementation such as:
the first thread runs the iteration and waits
the second thread runs the iteration and waits...
the last thread runs the iteration and notifies all the other threads to wake (and go to the next step)
I have tried the following but it doesnt work:
<br />
CommonClass commonObject = (CommonClass)o;
for (int i = 0; i < 4; i++)<br />
{<br />
Console.WriteLine("Thread " + Thread.CurrentThread.Name + " is in iteration " + i);<br />
lock (commonObject)<br />
{<br />
if (Interlocked.Decrement(ref threadCounter) == 1)
{<br />
threadCounter = 4;
Monitor.PulseAll(commonObject);
}<br />
else { Monitor.Wait(commonObject); }
} <br />
}<br />
Do you find this approach correct?
Can you please suggest feasible solution?
Thanks in advance

Disclaimer: although I have studied threading, I am no guru, so take my suggestion with a grain of salt.
Also I'm not sure of .NET threading syntax, so everything will be in pseudocode.
---
Have one thread act as a scheduler for the rest of the threads, telling them when they are allowed to run.
1. Start running each thread.
2. When a thread completes an iteration, tell it to Wait on some condition variable that is regulated by the scheduler thread.
3. The scheduler thread will do nothing until the wait queue is "full" IE all available thread are waiting, or the "running" queue is empty.
4. The scheduler broadcasts to all waiting threads, telling them to wake up and start running.

To do what you want you can use a locking mechanism on a data object and start the threads in order. Essentially the locking mechanism causes a side effect of putting the threads in the order that they are received at the lock.
HOWEVER, the order that the threads arrive at the lock is not guaranteed and thus your program may not run the order that you want.
I don't understand why you would use separate threads if the order that these operations be done is critical. If the order is critical, then you should use a single thread to process the operations in order to guarantee the order.

hello C# community,
I have a windows form with a tab control in it, that acts as the container for 6 or 7 tabs. I would like to add shortcut functionality, so that when a user presses the F3 key on the key board it will go to tab1 of the tab control, F4 to tab2 of the tab control.....and so on.
I know I read how to do this somewhere, I have been having trouble locating where that was. Is it a property on the individual tab page or is it in the tabcontrol?
perhaps someone knows off the top of their head.
thanks in advance,
FG

Impatient, aren't you?
This board is supported by volunteers who do this on their own time, not yours. You're not paying for support, so why are you bitching that you're not getting it fast enough??
Enable the KeyPreview property of your form, then handle the form's KeyDown event. Check for the hot keys you want and show the appropriate tab depending on which key was hit.

I could give him a rather drawn out solution, but he'd have to pay up to me through PayPal first. Oh and by the way, my solutions are As-is, no refunds

relax...I just thought it was not such a hard question for this tremendous community.... In any case, I did not think that my post was particularly "rude", if I offended you or anyone else here at Code Project, my sincerest apologies.
Why does everything have to boil down to money. No I am not paying for support, but I am not paying for you to scowl me because I added a short comment to my own post. A great part of being part of a community is knowing how to interact in a community.
just like you, I am a volunteer as well, and where I can, I help people that need the help.

P.S. a simple "I don't know" would have sufficed.....but thanks for your help anyhow.

How does "Turn the form's KeyPreview on and handle its KeyDown event..." translate to "I don't know how to solve your problem"?? Sounds like a solution that works to me...

Give people time to respond if they know. Impatience like that only is going to piss people off and allow them to be less likely to answer your question.
