How to work with sessions in c# programming in a project.
Govind

Well, assuming it's a web app, you shove stuff into the session and pull it back out again.
Do you have access to google ? Also, Visual Studio comes with something called MSDN, it's an online document store - full of info.
What I'm saying is, you're asking a very broad question, the sort that requires an article to answer it, not a forum post.

foreach(XmlNode node in doc.SelectNodes("//details/add/addr"))
Well, to be honest, I see no sign that you've done anything I've told you to do, to date. Your nodes are still named addr1, addr2 and addr3, which means the above XPath will never return anything. If you want the add node, then you want to use SelectSingleNode, and if you can't work out that to select the add node you need //details/add, then there's a serious problem here.

Managed Debugging Assistant 'ContextSwitchDeadlock' has detected a problem in 'D:\Project1\Project1\bin\Debug\Project1.vshost.exe'.<br />
Additional Information: The CLR has been unable to transition from COM context 0x1b1c30 to COM context 0x1b1da0 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.
I got this error...?
Im scared

Hi All,
I want to load a page using WebBrowser Control (see code below). I try to get the page content through DocumentText property in "DocumentCompleted" event handler, but it seems that the event won't be triggered. The "Navigated" event won't be triggered either. However, the "Navigating" event does.
I used to use HttpWebRequest/HttpWebResponse to grab webpage content, however, the drawback is that I can't get the full loaded page through it. What I mean by this is that maybe some javascript will execute to modify elements on the page after it's loaded, I call this page as full loaded page. I think using WebBrowser Control can overcome this drawback. It's just like a browser, and it'll execute those javascript after loading the page. But I can't make this control work correctly. Could anyone help me? I'm very appreciate.
Thanks
Jie

I need to start and stop certain windows services via a form application? How do I do that? I have to code to load all services in a list box but I need to load only certain ones and control them?
|
|
|
|

Hi,
To manage windows services you need to add a reference to
System.ServiceProcess in your application.
Then you can use the
ServiceController.GetServices() method to access all the windows services on your system.
To get the driver services that are installed on your system use
ServiceController.GetDevices() method.

how draw icon on each item in list box ??

Hello
This would take some effort. Better is to make a ListView instead, and associate it with an ImageList.

ok do u have example ..

Hello
1- Make an ImageList control from your ToolBox, and fill it with images
2- Make a ListView from your Toolbox and set the view mode to details or whatever suits you
3- Fill it with your items
4- Use the following code sample to associate an item with a certain image:
MyList.Items[X].ImageList = MyImageList;
MyList.Items[X].ImageIndex = Y;
Replace X, and Y with appropriate numbers.
Regards

i have this error
'System.Windows.Forms.ListViewItem.ImageList' cannot be assigned to -- it is read only
when i make
listView1.Items[0].ImageList = imageList1;
listView1.Items[0].ImageIndex = 0;
Palestine

You don't assign an ImageList to every ListViewItem, but to the ListView itself.
Each ListViewItem only gets the index of the icon from its parent's ImageList.
By the way, since I've seen so many of your questions here dealing with very basic information, may I suggest that you read through the appropriate tutorials in MSDN? There really are a lot of examples out there showing you the concept behind things so that you don't have to ask every detail here...
Regards,
mav

Hello
Sorry I didn't go online for sometime!!
About the property I gave you, it was a mistake:->. You should do the following instead:
1- Make a ListView, for example MyListView
2- Make an ImageList, for example MyImageList
3- MyListView.View = View.List;
4- MyListView.SmallImageList = MyImageList;
... and now you can set each item's image by the index
MyListView.Items[1].ImageIndex = 3; //For example
Regards

The following functions are suppose to print multi page Tiff images but they don't. If I have a 2 page tiff it prints 2 copies of page one. I can't figure out how to get to the next page. The code is adapted from http://en.csharp-online.net/index.php?title=Graphics%2C_Multimedia%2C_and_Printing_Recipes%E2%80%94Recipe_8_15[^]
