Simply content of Form not appers (as kind of infinite loop as I'm showing on link for image above).

How to solve this Error?? Error_2_Cannot implicitly convert type 'int' to 'int[]'

17-Apr-15 4:24

I can't see your link as that site is blocked where I am.

If you're saying that your form is completely blank, it's because your continuously looping code is running on the UI (startup) thread, constantly hogging the thread so it's can't respond to WM_PAINT messages coming from Windows.

You have to redesign your application so that this long running code is put in a background thread, freeing up the UI thread to do, well, UI stuff.

Um...

public int[] DC;
...
array[0].DC = 12;

You can't assign an integer value to an array!
So either change the declaration of DC, or change what you are assigning to it!

Drop the [] so you aren't returning an array.

Re: How to solve this Error?? Error_2_Cannot implicitly convert type 'int' to 'int[]'

Certainly, if your code read this, for instance:

int[] item = 1;

That would generate a compiler error because 1 is not an array of integers. If you only want one value, change it to

int item = 1;

See how [] has been removed.

hi
i have attached font in my C# WinForm program.

this is the code:

System.Drawing.Text.PrivateFontCollection privateFonts = new PrivateFontCollection();
privateFonts.AddFontFile(Application.StartupPath + @"\MyFont.ttf");
System.Drawing.Font font = new Font(privateFonts.Families[0], 120);
lblMSG.Font = font;

when i run in the solution i see the font excelent.

but after i make setup to my program, and i install and run the program

i cant see the font (i see empty...)

(Of course that i attached the MyFont.ttf file to my app folder)

and i got this error:

Parameter is not valid

Did you add the font file to your program folder? Usually if you add a font file to an installer the tool will add install the font in the system Fonts folder, not your application folder. The code you're using expects to find the font file in the same folder as the .EXE.

OK, the thing to do is to NOT change the code. You should be diagnosing what the installer is doing with that font file. Find out first, then react to it.

Is the file actually there? If no, your installer is in error. If yes, you're probably passing another path.

how do i make my program autorun when my computer open(windows service)?

Dave Kreskowiak16-Apr-15 4:29

Not enough information.

What is this program supposed to do? Does it require a user interface? Is it support to start doing it's processing when Windows starts, or when a user logs in?

Windows Service applications starts after Windows starts and do not show an interface at all. You'd have to write your application specifically as a Service application.

Create an application which will call the web services or do what ever you want...then make an exe..put that exe in C:\Users\arka\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup this location. As your computer will start your app within this path will execute.

That location doesn't start an app when Windows starts. That starts an app when that user logs in.
