No, it is not possible using the built-in controls. You may be able to build a custom menu item that looks like a tab. That seems a little strange though; are you thinking more along the lines of an Office Ribbon control?

After a lot of work I finally figured this out, turns out it's very simple.
I wanted to publish this as an article, but the submit wizard would not let me, it said it was too short. I could pad it, but I don't have time for that kind of *&^$.
Here it is:
<br />
<br />
try<br />
{<br />
lblRevision.Text = System.Deployment.Application.ApplicationDeployment. \<br />
CurrentDeployment.CurrentVersion.ToString();<br />
}<br />
catch<br />
{<br />
lblRevision.Text = "Debug";<br />
}<br />

I think that's a bit too simple for an article. Plus, it leaves out crucial information (this only works if you're deploying via ClickOnce technology) and it has some bad practices (it catches a general exception).

Hi,
I am a student and doing a project on "serialization and deserialzation of a hashtable content " and the primary pbjective is to use XML serializer to achieve this task as we will be dealing on multiple platforms. Since XMlserializer doesnt work with hashtables I am trying to add the hashtable contents to arraylist(as I will be storing multiple datatypes) and then serialize the arraylist. But I am having trouble adding the keys and value from hashtable to arraylist...WOuld someone please help me as I am stuck at this point...\\
Cheers
Lokesh
Now here is the piece of code snippet for serializing
static void serialize()
{
System.Int32 i = 26;
System.DateTime j = System.DateTime.Now;
System.String k = "this is a test";
System.TimeSpan l = System.TimeSpan.MaxValue;
//I have declared serializedhashtable as new hashtable in one of my class
group1.serializedhashtable.Add("0", i);
group1.serializedhashtable.Add("1", j);
group1.serializedhashtable.Add("2", k);
group1.serializedhashtable.Add("3", l);
// Create an instance of an array, and copy the content of
// the hash table to this array
ArrayList myarray = new ArrayList();
|

Hi!
You can iterate through the items in a Hashtable using foreach:
foreach (DictionaryEntry ent in group1.serializedhashtable)
{
myarray.Add(ent);
}
Oh, and by the way, your assignment for 'i' is wrong. It should be 42, not 26  .

Thanks for reply Mav. I had tried that before with
foreach (object obj in group1.serializedhashtable)
{
myarray.Add(obj);
}
But then when I try to serialize the arraylist I get an error "There was an error generating the XML document.".Here is the code snippet
// 'Open a filestream to write the contents
FileStream filest = new FileStream("newhashtable.txt", FileMode.Create);
XmlSerializer xs = new XmlSerializer(typeof(ArrayList), new Type[] { typeof(System.Int32), typeof(System.DateTime), typeof(System.String), typeof(System.TimeSpan) });
xs.Serialize(filest, myarray);
filest.Close();
Here are the exception details.

Thanks you,

In contrast to this if I add these variables directly into the arraylist(instead of copying them from hashtable) I can generate the XMl document without any errors.
For eg: If I add the variables directly into the array..then its no problem
myarray.Add(i);
myarray.Add(j);
myarray.Add(k);
myarray.Add(l);

I am writing a WPF application which shows video content.
The PC will run 24 hours a day and is protected from power loss by a UPS. If the mains power goes down for over a minute, the UPS software sends the PC into hybernation. When the power is restored the PC resumes, however... The application which was showing the video now shows nothing (blank space).
Is there a way of detecting the immanent hybernation in order to gracefully stop the videos, and restart them or the application when the PC resumes?

Looking at Microsoft.Win32.SystemEvents.PowerModeChanged might help.
xacc.ide
The rule of three: "The first time you notice something that might repeat, don't generalize it. The second time the situation occurs, develop in a similar fashion -- possibly even copy/paste -- but don't generalize yet. On the third time, look to generalize the approach."

Thank you that is definitely worth looking up.

I have a log-in window application. When the user presses the cancel button it kills another window by it's name and then it exits. The problem is that if somebody kills the log-in window by terminating the process in the task manager the other window is not killed.
One solution might be to have a surveillande thread which doesn't die when the mother-thread dies, and can't be killed in the task manager. As soon as the log-in window thread stops responding to surveillance messages it will kill the other window and then exit.
Is this possible?
I've also tried to have a form which spawns another form, but in the Task Manager there is only one entry (PasswordDialog.exe). If you kill this process everything dies and the window which I want to kill when the log-in window dies is not killed.

check the IsBackGround property of thread..............
My small attempt...
|
|
|
|
|
Doesn't work, window remains. I set IsBackground to true.
|
|
|
|
|
Implement the surveillance functionality as a windows service. That way you can easily let it run from a privileged account and a non-admin user won't be able to kill these processes.

Hi buddies,
There are lots of small size picturebox on one picturebox control says picMain.At a time, I am moving only 1 picture on picMain on Mouse_Move event. But,I see problem with moving picture. Moving picture gets blur or I can say It need some re-draw.
so,I have use Invalidate() and update() to make the solutions but not getting any solution.
Instead of picMain if I try same thing on form, then it work very smoothly.I think picture box take more time to re-draw compare to form.
Pls help !!!

I'm not sure what help you need. You've worked out the answer I would give, don't use pictureboxes, pretty much ever. Just draw the image yourself.

Hi Mr Graus.
My work is working fine only when child picture boxes are on form control, but now as my requirement got change, I have to move every child picturebox on picture box ctrl ( instead of form control ).
When i move the child picturebox on picture control from xy1 location to xy2 location then picture looks like blur ( it seems that its own ghost is following at each mouse_move event).I am not getting the smotheness in dragging just as we get in Visual studio in design time during dragging ctrl from toolbox.
pls reply
thx

You have alredy post that question, a few day ago...... if i am not wrong....
Your Same Post.....[^]
and my answer was...
Private dragging As Boolean
Private beginX, beginY As Integer
Private Sub PictureBox1_MouseDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseDown
dragging = True
beginX = e.X
beginY = e.Y
End Sub
Private Sub PictureBox1_MouseUp(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseUp
dragging = False
End Sub
Private Sub PictureBox1_MouseMove(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseMove
If dragging = True Then
PictureBox1.Location = New Point(PictureBox1.Location.X + e.X - beginX, PictureBox1.Location.Y + e.Y - beginY)
Me.Refresh()
End If
End Sub

please help me,
I want to store and retreave word document in sql server using c#.net
bobin

Create a BLOB in a table the database, serialize the word document to a byte stream and save it in the database. To recreate it, you would need to deserialize the byte stream and write it to a file. It's probably worth having a column with the original filename of the document in.

hi guys
i have a usercontrol which consists on a listview ,and two buttons(ok and cancel).
now i have placed this control on my windows form,
now i want when i press enter key so the event handler of button ok should fire,
like we do on normal
me.acceptbutton = buttonok (e.g)
but i cant do it here because buttonok is private in my user control. i have buttonok event handler which i can handle , but i want to user enter key for that .
any solution
thanks in advance
hello

Hello,
Add a read property from Type System.Windows.Forms.Button to the UserControl, and return the button instanz.
//UserControl "UCListView" code:
public Button AcceptButton
{
get
{
return okButton;
}
}
//Forms code:
this.AcceptButton = ucListView1.AcceptButton;
Hope it helps!
All the best,
Martin

thanks this can work, but dear if it is not less secure.
i will give my okbutton publicily to my user which i dont want to do.
coz in this way the user will have full access on this button because he can get
its refderence from
this.AcceptButton = ucListView1.AcceptButton
am i right ?
