Hi guys,
have been playing with WMI to add a network printer connection to a Windows XP pc. My environment consists of a server running Windows Server 2003 and Visual Studio 2005 and a test pc running windows xp. Further, I have setup a full domain controller environment.
I have managed to write the code to add the network printer and it works fine when installing the printer on the same machine the code is executing from i.e the server or xp pc. However, if I run the code from the server to install the network printer onto the test pc, it does not work. An exception is generated stating "Not Supported, the inner exception is blank. I can manually install the network printer on the test pc via the control panel, proving that the connectivity between machines is fine. The exception occurs when the mgtClass.InvokeMethod is executed.
1) If I specifiy the ip address of the test pc in the ManagementScope object does and when an object of Management class is instantiated does this imply that the network printer will be added to the test pc?
2)Using the AddPrinterConnection method from the WIN32_PRINTER class, is this the only way to add a network printer ?
3) To install the network printer on the server itself, omit the IP address,ipAddressOfClientPC, of the server from the ManagementScope object and it installs fine, provided the code itself is running of the server. So this leads me to believe its an issue with ManagementScope. However, if installing on the same machine as the code is running on then the username and password need not to be defined. So what do I need to do to the Management Scope object to make it work?
I used the WMI code generated by the WMI Code Generator, http://www.microsoft.com/downloads/details.aspx?FamilyID=2cc30a64-ea15-4661-8da4-55bbc145c30e,
I have added my code below.
If somone can point me in the right direction as to the mistake I am making, I would appreciate it.
thanks

It seems that AddPrinterConnection method is reserved for adding network printers to local machines rather than remote machines as to what I was trying to achieve.
To add network printer on remote machines you need to use rundll32 printui.dll,PrintUIEntry /?. This is a command line method of doing things however it can be easily incorporated into managed code.

I have a weird problem. I have a XML file something similar to the following
<StartingNode>
<!--XML Comment-->
<MyNode FirstAttr="value">
<MyNode FirstAttr="value">
<MyNode FirstAttr="value">
<!--XML Comment-->
<!--XML Comment-->
<MyNode FirstAttr="value">
</StartingNode> I loaded this XML file into a XMLDocument object and trying to iterate through the child nodes of StartingNode. I wrote
foreach(XMLNode objNode in objXMLDoc.GetElementsByTagName("StartingNode")[0].ChildNodes)
{
}These all works fine, but it takes the comments also as XMLNode. Is there any way to avoid this ?

Does network programming using C#.Net provide all the functionalities of WinPcap?
When I've to make use of WinPcap?

The only way to do this is to completely subvert the file system, or to not have real folders at all. Either way, sounds like a C++ task to me.

I suggest not to try that kinda application. I have seen that kinda application (e.g. FolderLocker and etc) on the net.. There are always some ways to hack.. and not so difficult to hack too.. Last two years, one of my friend is using that kinda of software (I think it called FolderLocker or something) to protect his file.. What this software does is that convert the folderid of his folder in registry (so, someone click on his folder then it will take you to recyclebin or network place or etc).. And it hide his folder as hidden system files.. that's all.. so, you can probably find how to unhide his folder and change it back to normal folder.. it's too easy.. I didn't see any software that does more advantages than those two steps..
Thanks and Regards,

Hello Shaz,
First, think of possible ways to do the task, e.g if i be doing it, i will be having a console program, running at the system-startup, with no interface, i.e. hiding the window itself. Naming it very similar to some very known process. So nobody may come to know it is something unusual running in the task manager. In that i would be checking if the user tries to access the folder. Whenever it does, i.e. catch the event, and pop-up the window for asking password. Putting in all the functionality to it. And for managing it, i.e. adding folders/files to secure, i would be having another application.
Just the thought!

Adeel

Hi,
I am creating a windows application that has a custom treeview/listview windows explorer.
How can I select the corresponding TreeNode of a selected ListView directory?
|
|
|
|
|
This is easy, the property SelectedNode (TreeView) can not only be read but also be written...
treeView1.SelectedNode = treeView1.Nodes[213];
//treeView1.Focus();
|
|
|
|
|
Hi,
I can follow that....but treeView1.Nodes[213] does not belong to the Selected ListView Item.
how can I find the Node that belongs to this ListView Item?
(ProjectTreeView.SelectedNode.FullPath + "\\" + ProjectListView.SelectedItems[0].Text);
