Hi,
I have some positive experiences with SIP and VoIP and I wish to give you an advice. If you need to learn about SIP you can start here: http://voip-sip-sdk.com/[^] They provide many sample programs and you can try them for free.
For me it was a good start to learn more about SIP.

I take it there's a question buried in this post somewhere? Perhaps a code snippet of what your having a problem with will help too.

Hello,
I'm using a treeview and I have selected several nodes.
Now I'd like to clear those node selections so that there are no nodes selected in the treeview.
The only way I've found to do this is to reload the treeview with the object, which sets it back to original state. But there's got to be a better way.
Anyone have any ideas?
Thanks in advance,
--PhB

As far as I know, a treeview can only have one selected node, which you can retrieve with the SelectedNode property.
Therefore, I'm not sure what are you refering to when you say that you have selected *several* nodes - maybe checked, like if the treeview is set to diplay checkboxes, and you refer to the checked nodes?
Anyways, if you want to "deselect" the one and only node that could be selected in a treeview, try setting the SelectedNode property to null.
Otherwise, if you want to "uncheck" any checked node, you must navigate the nodes, say recursively, and set the Checked property of each node to false.
Assuming you have a treeview named treeView in your form, create a method called setCheck and call it from wherever you want to perform the clearing of checked nodes (or checking them for that matter):
<br />
private void setCheck(TreeNode node, bool isChecked) <br />
{<br />
if(node != null) <br />
{<br />
node.Checked = isChecked;<br />
foreach(TreeNode child in node.Nodes) <br />
{<br />
setCheck(child, isChecked);<br />
}<br />
}<br />
}
Call this method like this:
<br />
bool isChecked = false;
foreach(TreeNode node in treeView.Nodes) <br />
{<br />
setCheck(node, false);<br />
}<br />
Hope it helps.

I am working with Sockets – I find this interesting, and I would call it a bug. It seems odd that the bytes that comes from GetAddressBytes is not valid for creating a new address given the prototype for it is the same. (A System.ArgumentException is thrown) let me know if you find this odd, a bug or if I am just not understanding how to use this interface correctly.
using System;
using System.Net;
using System.Net.Sockets;
using System.Windows.Forms;
using ThreadingEx;
namespace foo
{
[STAThread]
static void Main(string[] args)
{
IPHostEntry Host;
IPAddress Address;
IPAddress Address2;
Host = Dns.Resolve(“AnyAddressThatResolves.com”);
Address = Host.AddressList[0];
/*
** This will cause an error, the prototype is
** public IPAddress(byte[] address);
** and the GetAddressBytes is
** public byte[] GetAddressBytes();
*/
Address2 = new IPAddress(Address.GetAddressBytes());
}
}

I am using System.Management.Managementobjectsearcher in C# to read processor Number. Internally it uses COM objects.
So it gives error that System.Runtime.Interopservices.COMException and error message is Com object is not registerd.
This error comes only in windows98. It works well with 2000,xp,2003 etc...
So tell me how to solve this error..

I think the error message speaks for itself. You're trying to create a COM object (you didn't say which one) that isn't registered on the machine.
Either the .DLL that supplies this object isn't registered properly, or you're assuming that the machine has whatever COM .DLL you need and has it registered, when in fact it doesn't. You could also be trying to create a COM object that doesn't have the version you need installed on the machine.

Hello,
Why is it that oftentimes the SubTypes of my forms/usercontrols in the .csproj file are changed from SubType="Form" or "UserControl" --to-> SubType="Code" ? It's annoying as I need to open the .csproj in a text editor and manually change everything again from "Code" to "Form"/"UserControl"
Thanks for the help!

I have the SystemMonitor ActiveX control on a form and I try to register a custom performance counter.
I expect that after registering the counter with the OS, the user would be able to add it through this System Monitor ActiveX control on the form.
Yet, the Add dialog of this ActiveX does NOT contain the already registered counter.
Does anyone know what might be wrong?
Code snippet follows at the end.
BTW if I have the code that registers the counter in a separate executable, then the ActiveX has my counter. But if they're in one and the same executable, the ActiveX doesn't have it !?!

Hello,
I'm trying to use Microsoft Web Browser Control coding on c# (framework 1.1), what is the purpose of the wrapper used tlbimp utility.
1) I've load web page using Navigate method
2) then when i got the document, I’m running thru all the elements and make a "hooks" or register delegates on the events I’ve needed.
When I’m using OnClick event - all is OK,
but in others case ( e.g. OnActivate ) - the error occurred
When I’ve implemented such code using winAPI - the code done the right result.
On my opinion there is an error in .NET Framework, i.e. during implementing COM object wrapper.

Hi Room,
I have a small query.
I have an exe that is linked dynamically to another dll built in the .NET.
Now the exe was built in the VC6.0 environment but later shipped to (built in) to the .NET environment.
Now I have a class that inherits CProgressCtrl in both.
I checked the size of CProgressCtrl calss at runtime in both the exe and the dll and find that class's size in exe is 4 bytes smaller than the one in dll.
Could it be because the different environments both are being built on.
The problem is that the size of CProgressCtrl in the exe and the dll is different by 4 bytes that gives me a null CWnd pointer for my progress bar ctrl in the dll(I pass this pointer from my exe to this dll).
Please anyone suggest as to how do i solve this discrepency.
I think that there is a difference in the definition of the CProgressCtrl class in the "AFXCMN.H" of the VC6.0 anmd VC7.0(.NET) environment.

Hello!
I have a simple code that registers wake up event and executes an application, with CeRunAppEvent:
[System.Runtime.InteropServices.DllImport ("coredll.dll")]
public static extern bool CeRunAppAtEvent(string AppName, int WhichEvent);
bool rv = CeRunAppAtEvent("\\My Programs\\program.exe", NOTIFICATION_EVENT_WAKEUP);
Now I need to check if that event was registered previously, in order to prevent multiple registers of the same thing... but I dont find any useful function.
Note: CeRunAppAtEvent returns true altough actual event is already registered. It will only return false if there is any failure.

I have developed a Compact-Framework compliant .NET control (derived from System.Windows.Forms.Control) and would like to host this control in an HTML document on a Pocket PC. On the desktop, the following HTML code works fine:
<html>
<body>
<p>Hello World Control</p>
</body>
<object id="HelloWorldControl1"
classid="http:HWControl.dll#HWControl.HWControl"
height="500"
width="200" VIEWASTEXT>
</object>
</html>
However, on the Pocket PC, the control is not shown... Is it not possible to host.NETCF controls on Pocket IE?
Greets,
Ray
