Hello,
I'm wondering, what should I read about if I want to make a bandwidth monitor? And for just making sure what I mean with a bandwidth monitor I mean I want to show how much a user has downloaded and uploaded and how much (fast) he/she is uploading download at the current time =)
Any links? Articles?
I don't need articles specific for making a bandwidth monitor just subjects that when I know them I will proberbly be able to do a bandwidth monitor.
Thanks in advance dear code project members! =)

Yes, I have one here on CP i did ages back, still using it everyday. Search for MyDUMeter.

Thanks, I'll look into that! =) Do you have any topics that will learn me how to do it myself? I know I can look at your code and try to understand but I would like some article where they explain how things work =)

My project form are added dynamic,How are to load these forms by form name , like this.
Form f = new Form(“FormName”);
Thank you

Hi Richard. This almost looks like MS Access Basic syntax . In C#, forms are objects just like everything else, and are instantiated with their class name. If I have a form called "DocForm" in my project, I could add an instance of this form at runtime with the following:
DocForm f = new DocForm();
f.Show() Was this what you meant?
|
|

|

You can use reflection. A primitive implementation would be like this:
Type t = Type.GetType("FormName");<br />
Form f = (Form) Activator.CreateInstance(t);
That of course depends on what you mean with "forms are added dynamically", if the specified type is in the same assembly where the above code is executing, it should work.

Thank both of you!
The second answer is What I wanted,I have test it works.
Following is my test code
///---------------------------------------------------------------------------
private void button1_Click(object sender, System.EventArgs e)
{
Module[] moduleArray;
moduleArray = Assembly.GetExecutingAssembly().GetModules(false);
//In a simple project with only one module, the module at index
// 0 will be the module containing these classes.
Module myModule = moduleArray[0];
Type myType;
myType = myModule.GetType("WindowsApplication1.Form2");
Form f = (Form) Activator.CreateInstance(myType);
f.Show();
}
///-------------------------------------------------------------------------

Hi Richard. I think I misunderstood what you were looking to do. I'm glad you got the information you needed from Baris' post.

DateTime dt = DateTime.Now
gives me american date and not the british format d/m/y
i need the d/m/y
please
|
|
|
|

Internal representation of the DateTime object is not culture specific. It's the way you format it in ToString method.
DateTime.Now.ToString("dd/MM/yyyy");
note the capital MM if you put mm you will get minutes not the current month.
|
|
|
|
|
fantastic, i also noted in control panel (XP) a setting with American Language but I never knew about the ToString parameter very useful
|
|
|
|
|
This is also useful when using String.Format or Console.WriteLine. See the DateTimeFormatInfo documentation for more information, as well as my article, Custom String Formatting in .NET[^] for much more information, as well as links to other resources in the .NET Framework SDK.
Formatting strings properly in .NET is good to know.

did you see my code about the error today a copy of my Tabpage class wonder if you have any thoughts
|

Also, read the docs for the CultureInfo class. If you need to convert dates and times from one culture to another, you can use the current CultureInfo as well as a specified culture and use their Calendar property to help convert. Also, if you are creating international applications, it's better to use DateTime.UtcNow to get the coordinated universal time.

Is there a way to get the scrollinfo of the TreeView?
I have tried PInvoke but doens't seem to work. Anyone sheds the light?
below are my codes
using System.Runtime.InteropServices;
public struct SCROLLINFO
{
uint cbSize;
uint fMask;
int nMin;
int nMax;
uint nPage;
int nPos;
int nTrackPos;
}
[DllImport("user32")] public static extern int GetScrollInfo(IntPtr hwnd, int n, ref SCROLLINFO lpScrollInfo);
//calling part
const int SB_VERT = 1;
SCROLLINFO si = new SCROLLINFO();
GetScrollInfo(this.tvStat.Handle, SB_VERT, ref si);
//the si return is all zeros. Doesn't work apparently
thanx

Before calling GetScrollInfo you must set the cbSize and fMask fields of the structure, which is also documented for the GetScrollInfo API and is common among many APIs that take structs as params so that they know the size of the struct, which makes the API more robust.
To do this, use the static Marshal.SizeOf method from the System.Runtime.InteropServices namespace.

As per the subject, does anyone have even the faintest idea, using C#, of how I make a thumbnail screenshot of a webpage programatically? There are one or two ActiveX components out there that do this, and they render it exactly as IE would, which leads me to believe that it's some kind of functionality in IE. Perhaps it's somehow loading the website into an invisible browser window and taking a screenshot that way? I need to work this out for at least two or three tasks I'd like to implement solutions for. Please note that this has to be able to be completely automatic and doable from nothing more than a given URL.

I'm trying to set the text of an item of a TreeView to bold. When i set the node font, the node continues to use the same width space for drawing the text as where the font was "plain", so the label is trunked at the end. There's a way to update correctly the space of the node?
i've used this code before adding the node to the Nodes collection:
<br />
TreeNode node = new TreeNode("Test", 0, 0);<br />
node.NodeFont = new Font(treeView.Font, FontStyle.Bold);<br />
<br />
treeView.Nodes.Add(node);<br />
|
|
|
|
|
Yes there is a workaround:
node.Font = new Font(someotherfont..);<br />
node.Text = node.Text;
I know it looks silly, but it's the only workaround I found to force the treeview to recalculate the size of text with the new font/style etc.

This makes sense, since setting the Text property actually causes the class to send the TVM_SETITEM message to the underlying Tree-View common control with the TVIF_TEXT flag to set the text. If you set the text first, the underlying tree view probably isn't sent the text mask and hence the text is not sent. This would best be called a bug, but why it is necessary does make sense if you understand how the TreeView class works (i.e., it encapsulates its respective common control, as do most controls in Windows Forms).
