Use MyMDIChildClass.ActiveForm static property.

Hi,
I can't really use that because I want to also know which inactive forms are on top, and which ones are on the bottom.
For instance I can have 8 child forms open in a 2x2 layout with 4 on top and 4 below. I want to know which 4 are on top. Of course, only one of them is active and has focus. But I want to get a list of all 4.
Thanks,
R

I don't know if there is a function or a property to get the Z-Order of a form!! You can BringToFront() or SendToBack() but it isn't what you want!!
All I can think of is to track your Z-Order manually. When a form is clicked and activated it should update its Z-Order in a static list in the MDIChild class sending all other forms behind. This way you will check the list for the order of forms.

i had implemented the same thing using a arraylist
WHen a form is opened or clicked it is added to the ArrayList,
so u get the forms in the reverse order of the Arraylist.
Hope that works for you.
Thanks & Regards,

Is there any Windows Forms components that allow to sort the content of a table by the column? That is the user press the name of the column and the table is ordered ascending and descending.
And furthermore, there is a component that allow to search using one field or several of the table?
Now we use DataTable.
Thank you

DataGridView does that by default, and you can still do that in a ListView also by handling the ColumnClick event and sort the items youself.
123456uio wrote: component that allow to search using one field or several of the table?
Well, you can do this several ways, but a built-in method?!! I don't know! You can still search a ListView with FindItemWithText() method, but as long as you got a DataTable I prefer searching the table rather than the control.

Hey all,
I'm using SharpPcap to capture incomming and outgoing packets.
I can get the IP and port of the pack.
How can I tell which process is using the pack?
Thanks in advance,
Shy.

Run this at the command prompt:
netstat -b
This will show port no associated with the associated binaries.

|

Hmm... I'm afraid it's not gonna do me any good...
I need my application to determine that by itself...
I can pipe the result of running "netstat -b" and analyze it, but that's not the way I'm looking for...
Thanks for trying though... 
Any other ideas?

i read an article on msdn. they say it's imposible for 2 radiobuttons to be checked if they are on the same container! is it?
rzvme
|
|
|
|
|
Yes. Radiobuttons in the same container can only have one of them selected. If you want more than one item, use an array of CheckBoxes instead.

thought so. But i need the apperence of a radio button , and , apparrently, the behavieur of a check box. how can i do that? custom controls??
rzvme

I can tell you that would confuse people. They don't expect a radio button to work that way. It can be done, but you'd have to draw the control yourself.

the people i'm designing this for haven't even heard of radio buttons or checkboxs. they can't tell the difference! but what would be easier? drawing the control (how do i do that?) or inserting each control in a container (we are talking about at least 500 radio buttons)

These better NOT be all on the same form!! You'll run into a LARGE performance problem...

well, to be honest...at least 500 radio buttons (aprox 1500) on a form single form.  how big of a performance problem??
rzvme

1500 radio buttons??? Planning on 40" monitors?? ...And still having to scroll the form around...
Oh! And that's just the radio buttons. That's also another 1500 container controls to put them in!
How big of a problem?? Depending on the machine configuration, you could be looking at 2 minutes to start that form. The Controls container tends to get slower and slower the more you add to it. Also, repainting the form will take an eternity. If you want, put a small project together to test it out. Add a button to a blank form then add the code to create 1500 panels, groups, whatever, and 1500 radio buttons to the form. Run it and watch how long it takes to create them all, then try and scroll the form around.
1500 options... You SERIOUSLY need to rethink your user interface.

Hello

Sure it's not! set AutoCheck property of both RadioButtons to false. Then in the handler write the code that will Check/Uncheck the RadioButton. eg.
((RadioButton)sender).Checked = !((RadioButton)sender).Checked;
Even if you put more than a RadioButton on one container, they will be multiple selection according to the way you define in the handler.

Yes.
The purpose of radio buttons is to provide a single choise selection. The name comes from the mechanical push buttons used to select channel on old radio recievers. As you can only listen to one channel at a time, the previously selected button would pop up when you selected another channel.
If you want to provide a multiple choise selection, you should use checkboxes instead.

i know the kind of radio u speak, but i could always, somehow, press 2 buttons down at the same time
rzvme

Then use the CheckBox instead and change it's Appearance property to Button. Try it and see if you like it. It's FAR easier than custom drawing your own CheckBox control.

Yes, you could, but then you used two fingers. Perhaps if you had two mouse pointers it would be possible to press two radio buttons at the same time?

Say you have a variable named "Str" and it's value is "A", how would you change it to "B" not knowing which letter to start at? Could you use the same method for strings that represent numbers also? I have searched the net and haven't found an answer.
Thanks in advance.
