You need to realise that every time your page posts back the request is handled by a completely new instance of your page class. This means that your Hashtable field will be initialized every time.
Read up on the ASP.Net Page Lifecycle.
If you want to keep information between requests then you can store the data in a few places. Have a read up on the ViewState, Session and Application objects.

Hi every body , i want to Delete a .wav file from linux directory '/var/spool/asterisk/monitor/20080122-182544-1201006544.4.wav' from windows machine using c#.net, can any body write me some code related to this.

Unless you get your network admin to comprimise the entire security of the linux box, this is definately not possible from C#, neither will it be even if you are non-root on the linux box itself.
|
|
|
|
|
is it possible with any other developing way to delete file. e.g. telnet c#,ssh c#.net code or any other developing code.?
|
|
|
|
|
Can you get to the file via normal means ie putty or a mapped network drive?
C# isn't going to get you access to the box that you don't have using other techniques.

Any one know how to create an airbrush drawing tool.
|
|
|
|
|
I would guess that you will need to randomly choose a certain number of pixels within the brush area, and color them as needed. I think that the distribution function is uneven for that type of effect, so you should probably do something like picking a radius and and angle, then coloring that pixel. That way, the center has a higher probability of being colored than the outside. Good luck,
Sounds like somebody's got a case of the Mondays

You might want to google: Paint .NET, it is an entire drawing suite that I believe was written in VC#, if not VC# at least .NET. It is Open Source

Hi All,
I have a win app with two forms involved. Form1 opens up Form2. When I go to close Form2 I want to refresh some grids on Form1. I tried setting up a custom eventhandler but its kind of hokey. I need some way to call a method in Form1 from Form2. Does anyone have the best way to do this? I passed a Form1 reference to Form2 and tried to see if a public method that I declared in Form1 was visible but doesn't show up. So I went with trying to create a custom event in Form1 and calling it from Form2 but not sure the best way to do this, any ideas?
Thanks,
JJ

A quick question. Is Form2 shown modally? If so, at the point the Form2 is closed (right after it is declared in whatever method Form1 instantiates it), that is where you can refresh your data.
If the above situation doesn't work for you, I would consider reworking the whole public method thing you tried. Perhaps you didn't pass reference of Form1 to Form2, instead, you passed reference to a regular System.Windows.Forms.Form.
Something like
public void OpenForm(Form myForm)
is NOT the same as
public void OpenForm(Form1 myForm)
because Form1 is the actual object that would have your method contained in it.
That is probably why you didn't see that method show up in your Intellisense list. (I don't know, I'm just taking a guess...)
Hope that helps.

try myForm.Cursor=Cursor.Cross;, each Control has a Cursor property.
