Well what i am looking for, is the possibility to draw a form into image without displaying it...

Yes, the form class apears to have a 'DrawToBitmap' method that you could use.

Use the DrawToBitmap method of the form.
Despite everything, the person most likely to be fooling you next is yourself.

Hi,
I need a free obfuscator so no one can see my C# code.
any recommendations?
Thanks

If you've got Visual Studio Professional or above then you've got a Community Edition obfuscator in there.

I read it 5 times and I still don't understand what your problem is, or how you think we have enough information to try and help you. What have you done ? What is the code ? What is the error message ? Wat goes wrong ?

hi there,
I have written a code using C# 2003 in the past I need to run it on the 2005 environment , I changed every thing but I still got this :
var q =
from device in _manager.DiscoverAllDevices() select device.Name;
device and _manager are objects for bluetooth connection ,
the var q should contain every thing returned by the select,
but I do not know what should I change !
I think that the problem is from the statement, but I do not know how
Please help!
Note:the error was about missing (;) after device , _manager,..
There is always something to learn

Your example won't compile on either 2003 or 2005. It will only compile on 2008.
The equivalent code (roughly) in 2005 is:
Collection<string> q = new Collection<string>();
foreach(Device device in _manager.DiscoverAllDevices())
{
q.Add(device.Name);
}
I'm assuming that _manager.DiscoverAllDevices() returns something that when enumerated results in lots of Device objects. If not you will have to change the variable type for device.
Does this help?

We can't tell you the "exact" anything unless you explain your problem better. You need to give us more information:
What is photo?
What is the error?

I have some question regarding DB, if u fellows answer them:
a) What is diffrence between creating connection thru VS designer wizard And doing same by coding?
Which is better.
b) what these lines means
((System.ComponentMode1.IsupportIntialize)(this.dsComp)).BeginInit();
((System.ComponentMode1.IsupportIntialize)(this.dsComp)).EndInit(); auto generated by VS designer?
c)
this.textBox.DataBinding.Add(new System.Window.Forms("Text", dt, "State"));
this.textBox.DataBinding.Add("Text", dt, "State"));
textBox.DataBinding.Add("Text", dt, "State"));what is diffrence between these lines, I tried all for same control, they work fine with no error, But which one to use?
Thanks & regards.

The wizard can only ever put the code in your presentation layer. This is not the place for database code.
Doing it by hand means that you can create a proper DAL (Data Abstraction Layer)
humdumof wrote: System.ComponentMode1.IsupportIntialize
That does not exist. Please copy and paste the code properly. The actual interface is called System.ComponentModel.ISupportInitialize
Have you tried reading the documentation[^]?
I'm guessing that the object is a DataSet. If not then please tell us what it is, it wastes time trying to guess this sort of thing. If it is a dataset the BeginInit[^] and EndInit[^] methods are documented.
humdumof wrote: //dt for datatable, state is field in dt
this.textBox.DataBinding.Add(new System.Window.Forms("Text", dt, "State"));// line 1
this.textBox.DataBinding.Add("Text", dt, "State"));// line 2
textBox.DataBinding.Add("Text", dt, "State"));// line 3

The difference between line 2 and 3 is so basic I'd suggest you really need to read a beginners book on C# if you can't see what is happening.
this is a keyword that refers to the current instantiated object the code is operating within. For the most part it is optional. If you have a local variable with the same name as a class member then you need to use this. If not, then its use is completely optional you can use it or not. It makes no difference.
The difference between lines 1 and 2 can be found in the documentation. You can access the documentation by pressing F1 in Visual Studio. Or you can go to http://msdn.microsoft.com[^] and there is even a Vista Gadget where you can type in search terms and it will take you directly to the documenation.

Hello everyone!
I'm wondering if you could give me some tips on managing keyboard shortcuts in a winform application. I want to be able to create a dialog where the user can change the keyboard shortcuts to different commands. Right now I just add them to the ShortcutKeys property of a menu item and thats not very manageable.
Thanks in advance!

Hi,
Dear you have to store the text property of that object say in (setting.config) some ware and then each time you load your application you can read that setting.config file to put the that text for that object in the winform.
Regards

Not exactly sure how you mean. I think I understand that you want me to connect the ShortcutKeys property to a user setting in Settings.settings? If I create a new MenuItem class which has a command class connected to it this could work but what about the keyboard shortcuts that I want connected to a command which is not in the menu?
What I want it something like what Visual Studio has. All the different commands show up in a list and you can connect keyboard shortcuts to them. I also want plug-ins to be able to add their commands to the list.
Let's say I have all these command classes; NewFileCommand, OpenFileCommand, ExitApplicationCommand, etc. I also have a plug-in which has too commands; ShowGraphPlugin, ShowListPlugin. Now I need to get these commands into the keyboard shortcut configuration dialog and be able to connect a command to a keyboard shortcut. Not sure how to do that...

I was thinking, if I create a new menu item class that is connected to a command class/object. Wouldn't it be better if I concentrate on connecting a keyboard shortcut to a command instead? Then when the menu item gets the command it can somehow retrieve the connected keyboard shortcut (if any) and show it as it's own keyboard shortcut?
Then I guess all the keyboard shortcuts in the application would have to go through some manager class and I would have to have some list connecting commands to shortcut keys...
Is this good or bad?
