Guys,
I'm creating a very simple program that will run everyday a little bit of logic
Select
filter
output to file depending on the current date and year
Question: I used "console application" as my output type in c# but when I run it, it popup a console window. What I need is when I run my program no window will popup on the screen. Purely exe file. Which type will I use in c#?
Please help ASAP

A Windows Forms application. Then in the Main method you remove the call to the Application.Run() method. Instead call your logic from the Main method.

Oops, I replied to the first instance of this question, but his problem is that he's not using a Windows Forms application, but a console application which will display a console window. This can be prevented in Windows NT (not in Windows) but the program that would run this "windowless console app" would display the console window. I just suggested writing a Windows Service.

You could follow Colin's suggestion, but it's quicker simply to select 'Windows Application' in the Project Properties dialog, under Common Properties > General > Output Type.

You can run a console application without a console window in Windows NT (Windows 9x/ME does not support this). The problem is that you need a program that tells the console application to not show a window, so you end up in an infinite loop of trying to fix this.
I'd recommend writing a Windows Service which runs when the computer is booted (depending on the startup type of the service) and using either system credentials or a specific user's credentials (must have 'Log in locally' privileges, though). See the ServiceBase class in the .NET Framework SDK for more information.

Hi gurus,
Is there a way in C# to create a new instance of a class (clone)?
Or must I copy each properties of my class one by one like for C++?
Thanks
Best regards.

Hello,
i've seen that the most common Windows Forms controls have the property BorderStyle. I've designed some forms with all the controls with FixedSingle like border. But the ComboBox have not, yet, that property. Is there a simple way to change the border? the combo seems too much different to the other components in the program, i'd like to uniform the style.
Thanks

There's several other articles about this on this site as well in C# (though the syntax would be the only thing different between VB.NET and C# code). Just some other alternatives that shouldn't be hard to find if you search CodeProject (say "flat combo" or something like that).

Hello all
I have been trying for some time to write a good line control using C#. By this I mean a line control that can be used in graphical diagrams, graphic design programs and so on, to draw a line between two arbitrary points.
I believe this topic hasn´t been covered before, I´m trying to write an article on this but I have found a few problems which I can´t solve (I´m still new to .net and c#). Here it goes, I hope you guys can help me!
First, I inherit a control from System.Windows.Forms.Control. I override the OnPaint to draw a line between two corners of the control. This doesn´t work too well because you can´t see any of the controls that are behind the line´s control region. In other words, you get a nice white rectangular area encompassing the line and covering all that surrounds it.
Then I tried playing with various background colour settings. Interestingly, the "transparent" colours do not allow you to see what´s behind the control´s region - sure enough, it lets you define an alpha value for the background colour but you can´t see through it. Anyway, I also tried overriding OnPaintBackground, and playing with the control styles (UserPaint, SupportsTransparentBackColor, AllPaintingInWmPaint).
Lastly, I tried changing the control region of the line for a polygon that would more or less exactly encompass the actual line. So you only get a "white" area on a small polygon around the line instead of on a big rectangle. Guess what, although this looks quite nice there are occasions where windows doesn´t like it at all: when two of these lines are overlapping and are both moving at the same time, the system slows down a lot, and the rest of the controls aren´t correctly re-drawn.
As you can see, I´ve done my homework before asking. Can anyone give me a hand please? I just want a control to draw a line between two points :´(
Thanks in advance

hi,
I'm not sure why you want to make it as a control when this can be done directly.
Take the graphics object of the control on which you want to draw the line, and then graphics object gives the method "DrawLine" which takes two "Point" object for 2 corners of the line and you are done.
someControl.CreateGraphics().DrawLine(pen object , Point object , Point object);
Hope this will help you...
regards,
Aryadip.
Cheers !! and have a Funky day !!

hi, thanks for your reply.
well the whole point of having it in a control is to allow the user to drag the lines around, and so that the line can receive messages from other controls, for example.
Otherwise you have to build the control yourself, and replicate lots of code inside the parent form, for example to detect when the user clicked on the line and so on. That seems a bit crap, I really would not like to go that way.

Basically, you just need a surface that either hosts additional controls or handle all the movement of graph objects. The graph objects should maintain connection points to other graph objects so that when they move the lines is drawn between the connected graph objects even as they move.
There are a couple articles here on CodeProject that should introduce you to a couple different ways of doing this. You can either do a search or navigate the categories from the homepage.

ws2.dll and Bluetooth were first supported in Windows CE 4.0 (Pocket PC 2003 for consumer devices). Earlier devices optionally supported Bluetooth but used their own APIs rather than Winsock.
If you have a suitable unit, ws2.dll will be in the ROM of the device. It may not be displayed through ActiveSync's Explore function.

Hi,

If it is not managed, you will get an exception.
