All this thing happen when i use some other options of my application like changing color opening help file...
This is the font used to add fonts to my application
class PrivateFonts<br />
{<br />
[DllImport("Gdi32.dll", CharSet = CharSet.Auto, SetLastError = true, ExactSpelling = true)]<br />
private static extern IntPtr AddFontMemResourceEx(IntPtr pbFont, int cbFont, int pdv, ref int pcFonts);<br />
public System.Drawing.Text.PrivateFontCollection GetFont(string[] FontResource)<br />
{<br />
string NameSpc = System.Reflection.Assembly.GetExecutingAssembly().GetName().Name.ToString();<br />
System.IO.Stream FntStrm;<br />
System.Drawing.Text.PrivateFontCollection FntNc = new System.Drawing.Text.PrivateFontCollection();<br />
int i;<br />
for (i = 0; i <= FontResource.GetUpperBound(0); i++)<br />
{<br />
FntStrm = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream(NameSpc + "." + FontResource[i]);<br />
byte[] ByteStrm = new byte[(int)FntStrm.Length];<br />
FntStrm.Read(ByteStrm, 0, Convert.ToInt32((int)FntStrm.Length));<br />
IntPtr FntPtr = System.Runtime.InteropServices.Marshal.AllocHGlobal(System.Runtime.InteropServices.Marshal.SizeOf(typeof(byte)) * ByteStrm.Length);<br />
System.Runtime.InteropServices.Marshal.Copy(ByteStrm, 0, FntPtr, ByteStrm.Length);<br />
FntNc.AddMemoryFont(FntPtr, ByteStrm.Length);<br />
Int32 pcFonts;<br />
pcFonts = 1;<br />
AddFontMemResourceEx(FntPtr, ByteStrm.Length, 0, ref pcFonts);<br />
System.Runtime.InteropServices.Marshal.FreeHGlobal(FntPtr);<br />
}<br />
return FntNc;<br />
}<br />
}

Which line blows up ? This looks super nasty, why do you need to do all this ? Are you loading fonts from your resources ?

Yes i am loading fonts from resources

My other questions were 'why do you need to do that' and 'which line blows up'. How often does it blow up ? Can you reproduce it, and know it will blow up ( i.e. does it blow up every third time or something ) ? If you read your error message, it's telling you you have a name wrong. Have you tried making it so it doesn't require the exact name ?

This is where we started. Your font name is wrong.

Do I have to link some library files to the linker for the code to run??
How do I know which .lib files??

First issue you have is that this is the C# forum, and C# does not use a linker. Were you looking for the C++ forum, or have you spammed the entire site ?

MSDN is the place to search to find out what libs you need for specific C API calls. They tell you at the bottom what header you need, and what lib.

This[^] might help you in future. Or a good book.
Subtracting one DateTime from another returns a TimeSpan object.

Been really plugging your article, haven't you? 
Just kidding, of course.

Hello friends
in my windows form , there is a listbox which gets filled on the form load event.
on the button click event, the item selected in the listbox is deleted from the database and message box appears telling that the this item has been removed from the database
the problem is that I want that after the messagebox is closed, the list box should be refreshed now holding the items that are now currently in the databse and the item I have just deleted should not appear in the listbox.
How will I achieve this?
Looking forward for ur kind suggestions on the problem.
Thanks
Sadaf

Clear the contents of the listbox and fill it again. You can also just remove the item you have just deleted but in that case listbox won't contain any items that have been added after your programs startup and will contain items that have been deleted by other users.

re-populate the list box again from the Database. thats the safest way I think
