Hi.
The option for this is to create your custom control that will be repainted as
line.
Then create events for the control so it behaves the way you want to.
Happy coding !


With regards,
Dan Fat

Is it an web based application. If so, Its better to use javascript.
But as per my experience it is not a good proffesional approach. Best way is to
use flash actionscript.
 
If you are developing an exe application, use can use system.drawing and its
namspaces to inherits the pen and drawing tools. It is an interesting one.

Hi

I like to know how to get the drive on which my application will be running

so if i run the app from d:\abc\xyzz\asd\my.exe

i would like to get the "D:"

Keep in mind that the original poster doesn't just need to draw a line.
That would be easy.  He needs to be able to click on or near the line
and have the line be selected.

Hi

you can write this code to get the full path for application

string path  = Application.ExecutablePath;


then you will write this code to get the drive letter


string driveLetter = path.substring ( 0 , path.indexof(":") );

Dear Mahfouz
if you want it a desktop application"C#"
you can use drawing library to draw the line
and you need three event "Form1_Mouse......."
mouse down
mouse up
mouse move

int i=0;
int j=0;
bool flag = false;

mousedown(sender,e)
{
i=e.x
j=e.y
flag = true;
}

mouseup
{
flag = false
}

mousemove(sender,e)
{
if(flag)
drawline(i,j,e.x,e.y)
}

then  you need to save the point and if you click any point you ask if the point
is related to the line

Also if you are on your web page you could use

path = Page.Request.MapPath("/");

and then parse out the first drive letter as in the previous post.

You'll have a line defined by its start and end points.  You will need
to define handlers for the mouse down and mouse move events, and maybe
the mouse up event.  In the mouse down event, you check to see if you
are close enough to your line to select the line.  If you are, you
highlight the line somehow and you store the current mouse position.  In
the mouse move event, you compare the current mouse position to the
previous mouse position and move the line start and end points by the
same amount.  Perhaps you redraw the line now, or you draw a faint copy
of the line, or perhaps you do not redraw anything now.  In any event,
the last thing that happens in the mouse move event is to replace the
previous mouse position with the current mouse position.  Finally, in
the mouse up event, you redraw the line in its final form.

Come to think of it, you could live without the mouse move event if you
don't need to show the line moving.

Yahoo! Groups Links

Hi,

Please consider the following case:

I have a treeview control in a page. Only name and value property is
set for each treenode. The 'SelectedNodeChange' event is handled and
another new page is loaded based on the selected node's value. I have
used UpdatePanel and associated controls to show a 'Please Wait'
message when a tree node is clicked. The message starts showing
immediately after clicking the node and stops showing after a new page
is loaded. So far this is fine and working perfectly.

The problem is when i right click on a treeview node (which appears as
a link), the 'Open in new tab' option is shown disabled in the browser
menu (i mean the menu which appears after right clicking on a link). I
found that if i set the navigate url property of treenode, then the
'Open in new tab' menu is shown enabled. But in that case the 'Please
Wait' message doesn't show.

The problem is, if i do not assign any hardcoded url to a link
(treeview node in my case), the 'Open in new tab/window' option is
disabled. But if i assign a hardcode link, the browser handles the
request automatically. In my case, since i am loading another page,
the 'Please Wait' message is now shown any longer.

Is there any option to enable 'Open in new tab' without assigning
hardcoded link?
Or is there any option to stop browser to emmediately send request
when a hardcoded link is clicked?
Any help would be greately appreciated.


Regards,
Tanvir.

I have the same problem .

Well i solved it in the following way:

1. I registered a client script for each node of treeview:

--------------------------------------------------------------------------------\
----------------------------------------------------------------
public static void RegisterTreeNodeEffect(System.Web.UI.Page page,
System.Web.UI.WebControls.TreeView treeView)
{
             StringBuilder effectScript = new StringBuilder();
             int i = 0;
             foreach (System.Web.UI.WebControls.TreeNode tn in
treeView.Nodes)
             {
                 effectScript.Append("document.getElementById('" +
treeView.ClientID + "t" + i.ToString() + "').onclick=function(){"
+                       "StartNewPageEffect();" + "};");

                 i++;
             }

             page.ClientScript.RegisterStartupScript(page.GetType(),
"EffectScript", effectScript.ToString(), true);
}
--------------------------------------------------------------------------------\
----------------------------------------------------------------

2. In the code behind define the client function:
--------------------------------------------------------------------------------\
----------------------------------------------------------------
function StartNewPageEffect()
  {
             // start your effect here....i.e. a loading icon
             // you dont need to stop or hide the effect since it will be
automatically hide after browser gets the new response

             return false;
}
--------------------------------------------------------------------------------\
----------------------------------------------------------------

Thats it.

Tanvir Faraj

Hi,
 
I have some forms where the Icons dont show up in the Windows TaskBar. Instead
the main Program Form's icon shows when these forms open.
It's not all of the forms just some of them.
Any ideas for fixing this?

Greetings!

Our flagship application is written in C++ using MS Visual C++ 6.  When
the application starts, it shows some buttons across the top and down
the left side, but most of the space is taken up by an HTML screen that
displays a set of boxes containing information about objects.  The
buttons down the left side of the screen control filters that determine
which objects get displayed.  The application passes an ADOConnection
object to the HTML screen, and JavaScript code applies the filter and
displays information from the resulting recordset.

The problem is that a clause in our biggest contract in many years
requires that our application consume no more than 40% of available
memory on the computer, and somewhere there's a memory leak that
increases usage every time a user clicks a button to change the filter.
We are at our wit's end trying to track this down and get rid of it.  It
appears to be buried inside the CWebPage class we're using to display
the HTML page.

It occurred to me this morning that it ought to be possible to come up
with a C# class library that would manage the web page.  I found a neat
little tutorial illustrating how to invoke a C# class library from a C++
application, and it shouldn't be hard to find out how to display a web
page from inside C#.  (Although I wouldn't mind a hint:  what class
should I use?)

The most pressing question I have is this:  I would like to display the
page using an existing window from the C++ application.  I could pass
the window handle into the C# library, or even pass in a reference to
the CWnd object, but what then?  How do I display my HTML screen inside
that window instead of creating a new window for it?  Or maybe the
existing window would end up being the parent of the window that
displays the HTML screen?  What would be the best way to do this?

Thank you very much!

RobR

Below are some links that may help you. The hardest part was extending the
browser control with COM Intereop to capture some of the events that aren't
exposed directly. In our case one of the events we needed to catch was the
WM_DESTROY event so we could do additional processing when a new window was
closed.

Subject: [C#.NET] Displaying a web page in an existing window

Greetings!

Our flagship application is written in C++ using MS Visual C++ 6.  When
the application starts, it shows some buttons across the top and down
the left side, but most of the space is taken up by an HTML screen that
displays a set of boxes containing information about objects.  The
buttons down the left side of the screen control filters that determine
which objects get displayed.  The application passes an ADOConnection
object to the HTML screen, and JavaScript code applies the filter and
displays information from the resulting recordset.

The problem is that a clause in our biggest contract in many years
requires that our application consume no more than 40% of available
memory on the computer, and somewhere there's a memory leak that
increases usage every time a user clicks a button to change the filter.
We are at our wit's end trying to track this down and get rid of it.  It
appears to be buried inside the CWebPage class we're using to display
the HTML page.

It occurred to me this morning that it ought to be possible to come up
with a C# class library that would manage the web page.  I found a neat
little tutorial illustrating how to invoke a C# class library from a C++
application, and it shouldn't be hard to find out how to display a web
page from inside C#.  (Although I wouldn't mind a hint:  what class
should I use?)

The most pressing question I have is this:  I would like to display the
page using an existing window from the C++ application.  I could pass
the window handle into the C# library, or even pass in a reference to
the CWnd object, but what then?  How do I display my HTML screen inside
that window instead of creating a new window for it?  Or maybe the
existing window would end up being the parent of the window that
displays the HTML screen?  What would be the best way to do this?

Thank you very much!

Isn't it cheapter to just fix the problem? These issues are fairly easily
resolved.



The "memory leak" is most likley in the interop layer associated with the leased
object lifetime. Here's how to find it. Force a garbage collection after 1
minute of idle time and after 6 minutes of idle time. Then dump the stack.
Examine the roots. There's your memory leak. I have posted a walkthrough on this
here http://support.microsoft.com/kb/555916, it is somewhat (but not exactly)
related to your problem.

The problem is that this is not a .Net managed control.  This is an old
library used in a Visual C++ 6 application, and it's not even a library
we developed.  We found a single reference on the Internet saying that
there is a memory leak in this library, but we've never found a
workaround or fix.  So, I want to get rid of this library.

Hi Rob,

    You may use c#.net to create a COM control (OCX) to show your webpage. That
is very simple.
    Then you use this OCX in your c++ code.

Good luck.

Hi all:

I have a new web application using c# that should allow user to upload video
with maximum 5 minutes, the plroblem appears when displaying video, the video
doesn't start playing before it completly downloaded, also when I tried to use
plyer skin, it works fine locally, but when I upload it on the server it didn't
give me anything (white page).

I want my video to display like you tube, I don't know what I miss, my server
operating server is windows server 2003, does it need any thired party to
install or what?

thanks in advance..

Hi,

i am having a problem here regarding the WPF control.
i used the Microsoft office speardsheet 11.0 in windows forms.
now i wanted to use it in wpf control. but i am not able to.

any ideas how to do it. or any other controls or workarounds for this one.

Thanks and Regards,
Hari

Why in the world would you use an old-school OCX when you can use a
WebBrowser control in .NET? Sheesh!

Sorry, should clarify that. You can expose C# to COM all day long. And if
you don't want to do that, you can expose it via a service that C++ can call
all day long.
