Hi all
can any body help me to know how to add a panel control as a treenode in a treeview control
thx all in advance 
|
|
|
|

The .NET treeview allows you to add objects in the Tag property, so the node can reference a panel control. Click the node, get the Tag and then you have access to the panel and its control collection.
In the tree, only Node objects will exist in the node collection so you can't specifically make a node a panel, but using the Tag you can make a node essentially the same thing.

i tried to do this
treeView1.Nodes[0].Tag=panel1;
but it didnt worked
may i didnt understand your words right

That works for me. Exactly how does it not work? Remember you will have to cast the object out of the Tag, likes this:
Panel panel2;
treeView1.Nodes[0].Tag = panel1;
panel2 = (Panel)treeView1.Nodes[0].Tag;
panel2 doesn't have to be a control you dragged onto the form, it could be an object of type Panel. If you are using the panel object as a way to get at a collection of controls, then you have to read the Tag data into another panel object, then get to the controls through the new panel object (as in the example above).

Hi!
I'm trying to make a C# video player and i need to auto hide the mouse cursor in fullscreen after some time. I've managed to hide it and show it, but i get weird bugs. The longer the cursor remains still the longer it takes to hide it and show it and i don't know wtf is going on Here's my code:
int mishImobilan = 0;
void MainForm_MouseMove(object sender, MouseEventArgs e)
{
mishImobilan = 0;
Cursor.Show();
}
void ProvjeraMisha()
{
if (mishImobilan < 10)
{
Cursor.Show();
}
else
{
Cursor.Hide();
}
if (Cursor.Position == Cursor.Position)
{
if (mishImobilan < 30)
{
mishImobilan++;
//Cursor.Show();
}
if (mishImobilan >= 30)
{
Cursor.Hide();
mishImobilan = 30;
}
}
else
{
mishImobilan = 0;
Cursor.Show();
}
//testic.testBox.Text = mishImobilan.ToString();
if (mishImobilan >= 10)
{
Cursor.Hide();
}
}
// This is the timer
void tajmerZaNest_Tick(object sender, EventArgs e)
{
ProvjeraMisha();
}
And also, does somebody know where can i get a separate Managed DirectX redistributable installation? I need it for my program but i have December 2005 release with the complete DX redist that weighs about 47 mb, and thats really big. All i need is a couple of managed dx dlls...
Thanks!

Can somebody tell me what font and font size can draw fastest in Compact Framework(like MS San Serif or Tahoma or,...). What's i should choice among them? Thanks
Nothing

Probably a fixed-width font but I doubt there's much difference in speed unless you do your own calculating of positions in which if you're using a fixed-width font such as Courier New you can optimize the code by making a few assumptions.

Eh
you did helped me well last time. but i can't post any message's on my previous topic.

I for one, do not have a clue what you are talking about.
Perhaps try asking a question, preferably with a meaningful subject line.

Hello!
In my project I try to use LDAP services via P/Invoke (it's a must . All the stuff worked fine till the certain moment. Now when I need to go thru the object's attributes I just stumble upon the problem that I can't get an attribute other then the first!!! Just because function ldap_next_attribute returns a zero value instead of the pointer to the next attribute in the array. Here is the code:
<br />
private static NameValueCollection WR_LDAPGetAllAttributes(IntPtr pEntry)<br />
{<br />
NameValueCollection nvcAttrVals = new NameValueCollection();<br />
IntPtr pBer = new IntPtr();<br />
IntPtr ppValue;<br />
int iValueCnt=0;<br />
IntPtr pAttribute = ldap_first_attribute(pLDAP, pEntry, out pBer);<br />
while (pAttribute != IntPtr.Zero)<br />
{<br />
ppValue = ldap_get_values(pLDAP, pEntry, pAttribute);<br />
if (ppValue == IntPtr.Zero)<br />
{<br />
nvcAttrVals = null;<br />
return nvcAttrVals;<br />
}<br />
else<br />
{<br />
iValueCnt = ldap_count_values(ppValue);<br />
if (iValueCnt==0)<br />
{<br />
nvcAttrVals = null;<br />
return nvcAttrVals;<br />
}<br />
else<br />
{<br />
string sAttrVal = "";<br />
int ippValue = ppValue.ToInt32();<br />
for (int z = 0; z < iValueCnt; z++)<br />
{<br />
ippValue = ippValue + sAttrVal.Length * z;<br />
IntPtr pVal = Marshal.ReadIntPtr(new IntPtr(ippValue));<br />
sAttrVal = Marshal.PtrToStringAuto(pVal);<br />
nvcAttrVals.Add(Marshal.PtrToStringAuto(pAttribute), sAttrVal);<br />
} <br />
}<br />
}<br />
pAttribute = ldap_next_attribute(pLDAP, pEntry, ref pBer);<br />
}<br />
return nvcAttrVals;<br />
}<br />
here is the origial definitions:
<br />
PCHAR ldap_first_attribute(<br />
LDAP* ld,<br />
LDAPMessage* entry,<br />
BerElement** ptr<br />
);<br />
[DllImport("Wldap32.dll", EntryPoint = "ldap_first_attribute", CharSet = CharSet.Auto)]<br />
private static extern IntPtr ldap_first_attribute(<br />
IntPtr id,<br />
IntPtr entry,<br />
out IntPtr ber);<br />
<br />
PCHAR ldap_next_attribute(<br />
LDAP* ld,<br />
LDAPMessage* entry,<br />
BerElement* ptr<br />
);<br />
[DllImport("Wldap32.dll", EntryPoint = "ldap_next_attribute", CharSet = CharSet.Auto)]<br />
private static extern IntPtr ldap_next_attribute(<br />
IntPtr id,<br />
IntPtr entry,<br />
ref IntPtr ber);<br />
I will appreciate way much if anyone help me. Thank you in advance.

I have a class called Options that I vant to serialize in XML that containes a few variables and a couple of functions. My question is how to access these variables from another class so that I may change their values.
If I just declare the variables " public ", I can't access the from my MainForm class (by means of Options.var_name). If I declare them " public static ", I can access them via Options.var_name, but I get an error when trying to assign them a new value.
Any suggestions are welcomed. (Sorry if this is a stupid question, I'm a beginner.)

What does this have to do with seraialization?
Anways: what is the error message you get?

public class MyClass<br />

public static int MyStaticVariable = 0;<br />

public class MyTest<br />
{<br />
<br />
private void MyMethod ()<br />

<br />
}<br />
This code works. So how are you trying to access the static variable?
