Thanks guys.
I meant to get the user's name in/on the system.
It's to store session state information along with their username.
I have it now.
Thanks again,
Conor.

I've run into a problem...
I used
String username = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
to get the username. And this works fine when accessing the webpage if it's on my own computer but when I publish the site and access it from anywhere else, it returns “NT AUTHORITY\NETWORK SERVICE” for the username.
Is there any way to have this work for people accessing the site from somewhere else as well?
Thanks,
Conor.

Hi,
I have a UserControl in which it has a TableLayoutPanel and the TableLayoutPanel contains some labels and buttons. When I change the Enabled property of the form that contains this UserControl on run-time, naturally the UserControl that is in it becomes disabled too. But, the forecolor of the labels that are contained within that UserControl's TableLayoutPanel change (they become gray) which is I do not want. I tried changing forecolors of the labels in EnableChanged event but didn't help. How can I specify a forecolor for a label when it becomes disabled?

if (thefile1.Exists)
{
File.Copy(Server.MapPath("RtfFilesPath") + "\\voice\\" + txtOriginalName.Text.Trim() + ".wav", Server.MapPath("RtfFilesPath") + "\\voice\\" + txtFilename.Text.Trim() + thefile1.Extension);
GetData();
}
hello frns
the above is the snippet of code i used in my application what i am doing is copying a file and saving it with the someother name its working fine, but the actual problem is i'll be having two types of files in my folder one is .mp3 and .wav .

Hi,
On clicking a search button, a datagridview is populated with data.
Each row has an extra column to display a button in it. This is the details button for each row.
The problem is that when I click on the search button to reload the datagridview, a new details column gets added to the first column of datagridview.
How is it possible to prevent adding extra column to the datagridview each time I click the search button?
Please note, I only get the details column as the last column, the first time the datagridview is loaded.
This is how I am adding the details column dynamically to the datagridview.
I think it is to do with the line which has new in it...
dsPricesSourcesBest = Business.clsSecurities.PricesSourcesBestGet(intCountryID, intSectorID, intSecurityID);
defaultView = dsPricesSourcesBest.Tables["PricesSourcesBest"].DefaultView;
dtPricesSourcesBest = dsPricesSourcesBest.Tables["PricesSourcesBest"];
dgvSecurityPricing.DataSource = null;
dgvSecurityPricing.DataSource = defaultView;
dgvSecurityPricing.ReadOnly = true;
//get the count of the records...
lblCount.Text = "Total Records : " + defaultView.Count.ToString();
//Not sure if the problem is being caused because of this line????
DataGridViewButtonColumn detailsCol = new DataGridViewButtonColumn();
detailsCol.Name = "Details";
detailsCol.Text = "Details...";
detailsCol.UseColumnTextForButtonValue = true;
dgvSecurityPricing.Columns.Insert(dgvSecurityPricing.Columns.Count, detailsCol);
dgvSecurityPricing.AllowUserToAddRows = false;
|
|
|
|
|
This is how I solved it.
if (dgvSecurityPricing.Columns.Count == 9)
{
//there should be only 9 columns including the Details column...
dgvSecurityPricing.Columns.Remove("Details");
}

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 ?

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.
