hi,.S.Rod.
I'm extracting all links from a webpage,after I'use
doc.createElement("link");
how I get all links from page "codeproject".
|
|
|
|
|
Semantically a link tag is not an hyperlink tag. An hyperlink tag is known as an anchor. A link tag is what refers to external javascript or css files.
To know which method, collection or member to call, you must first define what you call a link. And then, either you have a collection ready for use (such as doc.anchors for all hyperlinks), or you'll have to parse the entire DOM tree matching tag names.
Good luck!

Hello,
In my project I have two forms:
frmMainForm (Mdi parent)
frmLogon (dialog)
- components on frmLogon: (edUserName, edPassword, edDatabase) - TextEdit
(btnOk, btnCancel) - Buttons
In frmMainForm Load event i wrote this code;
{
frmLogon Logon = new frmLogon();
Logon.ShowDidalog();
if (Logon.DialogResult == DialogResult.OK)
{
this is my problem, I don't know how can I get values from edUserName, edPassword... to build connectstring.
I mean something like that string username = Logon.edUserName.Text;
}
}
I hope you understand me
Thank you for answers

The best thing to do is to implement your dialog results through properties of the frmLogon, i.e.
In your frmLogon, you begin by declaring some private fields
private string userName;<br />
private string password;<br />
private string databaseName;
Then, you create the properties (also in fmrLogon)
public string UserName<br />
{<br />
get<br />
{<br />
return userName;<br />
}<br />
set<br />
{<br />
userName=value<br />
}<br />
}<br />
<br />
public string Password<br />
{<br />
get<br />
{<br />
return password;<br />
}<br />
set<br />
{<br />
password=value<br />
}<br />
}<br />
<br />
public string DatabaseName<br />
{<br />
get<br />
{<br />
return databaseName;<br />
}<br />
set<br />
{<br />
databaseName=value<br />
}<br />
}
After this, don't forget to update your variables when the user presses the OK button. Something like
private void button1_Click(object sender, System.EventArgs e)<br />
{<br />
this.UserName=textBox1.Text;<br />
this.Password=textBox2.Text;<br />
this.DatabaseName=textBox3.Text;<br />
}
Having done this, you are now able to access your dialog results in the main form through the properties. For example...
frmLogon Logon=new frmLogon;<br />
<br />
if(Logon.ShowDialog()==DialogResult.Ok)<br />
{<br />
<br />
this.myTextBox=Logon.UserName +Logon.Password +Logon.DataBaseName<br />
}

I have a DLL which may be called by more than one exe or more than one instance of an exe. I need the DLL to be able to figure out which exe it is or more precisely, I want it to access some config information regarding the exe.
I am currently trying to fool around with
System.AppDomain.CurrentDomain.SetupInformation (this is in my DLL to get info on the app)
but not sure if that is what I should be doing.
Any clues?
Thanks

Figured it out. I need to use System.Configuration and create an app config file to do what I need.

Can anyone tell me the correct code to use to clear the checkmarks (not the items) in a CheckedListBox? I want to do this as sort of a reset function to allow the user to start over making their selections.
Thanks for any help you can give me.
|
|
|
|
|
for( int i=0 ; i < checkedListBox1.Count; i++ ) <br />
{ <br />
checkedListBox1.SetItemChecked(i, false); <br />
}
Earlier I provided the solution for normal Checkbox.

You left out the refences to Items. But it works. Thanks.
It should be:
for (int i = 0 ; i < checkedListBox1.Items.Count; i++)
{
checkedListBox1.SetItemChecked(i, false);
}

I am creating a strongly-typed collection class for a custom class using the CollectionBase class. I have added a Sort() function to the class with the following description:
public void Sort()
{
myClass[] tempArray = new myClass[List.Count];
tempArray.Initialize();
List.CopyTo(tempArray, 0);
Array.Sort(tempArray);
List.Clear();
foreach(myClass val in tempArray)
List.Add(val);
}Is there a better way to do this, performance wise? Or is this implementation a decent one?
FYI: The list count for this collection will be very large when used in the application.

Maybe there is another way of doing it, but the only one that passes through my mind now is the SortedList container.
Do you really need to have a Sort method or can the list be sorted all the time? If this is the case, then deriving from or aggregating a SortedList can give you the best performance.

The collection cannot be automatically sorted. In use, the collection will usually be unsorted. Only on occasion will sorting be necessary. Thanks.

Since you're inheriting from CollectionBase you can use the underlying ArrayList's Sort method. That will (should anyway) in turn call the underlying Array's Sort method.
You can access the ArrayList by the protected InnerList property on the CollectionBase.

It actually calls an quicksort implementation. Saw it many moons back. Quite fast as well.
Hey leppie! Your "proof" seems brilliant and absurd at the same time. - Vikram Punathambekar 28 Apr '03

If the data is not already sorted (which is the worst case of the QuickSort algorithm)

hi,
i have a databound datagrid control in a winform. i need work arounds for some problems.
1. When i click the last row in the datagrid a new row is automatically added. i need to control this new row addition. Before adding a new row I need to check existing rows in the datagrid and validate against some criteria. Depending on the values existing in the datagrid I want to reject or accept the addition of the row. How can i do this. I tried onRowchanging event of the table the datagrid is bound to but got into some other problems.
2. How can i undo a latest edit made in a databound datagrid again based on some criteria.
3. I have included a combobox inside the datacolum and the combobox again includes a tree view inside. i got most of the job done but whenever i try to add a new row in the datagrid it adds up three new rows. Then when i click on the first of the newly added rows the other two disappear but when i click on the 2nd and 3rd i get the arrayindexoutofbounds exception. Any solutions for this?
hope I get some replies.
Thanks.

When I call StartService() Web Method of my Web Service, aspnet_wp.exe consumes around 100% cpu utilization. What is wrong with this?
[WebMethod]
public void StartService()
{
threadListener = new Thread(new ThreadStart(Listen));
threadListener.Start();
}
private void Listen()
{
//Some code for creating a init tcp listner
threadListener.Suspend();
}

Plz,
examine the memory consumption
using some tools. Tools such as System Monitor or Task Manager can isolate
those processes. When using System Monitor, if both the "Private Bytes"
counter and the ".NET # of Bytes in all Heaps" counter increase at the same
rate, this is evidence of managed memory consumption. Look at the size of
allocated managed memory and consider what the garbage collector is doing.
The allocation profiler might be helpful to you:

I want to make a browser likes IE, but .NET doesn't provide a web browser control ( I want something that I can configure it easily, not hard). Please help me.
|
|
|
|
|
The VS.NET Toolbox window can be customized to add ActiveX controls such as the web browser control. When you drop this control onto your form, interop libraries will be automatically built and used.
|
|
|
|
|
please tell me how to use that control( and what they are)!!!
|
|
|
|
|
Tutorial[^]. What this article does not say is that, instead of using the cmdline to extract what's known as interop libraries, you can let the VC#.NET IDE do it for you, by simply dragging the "Microsoft Web Browser control" COM component from the Toolbox to your Form.

I need to convert a string variable to an array of integers (An ASCII code for each character) and send it over to a Fortran code.
First, I have converted the string var. to an array of char (see below), but how can I convert this (kurt) to an array of integers?
string SetupPath;
char [] kurt;
int [] intFilePath;
