Platform independent size_t Format specifiers in c? -

-

I want to print a type of type size_t in C but it seems that Size_t is the nickname for different variable types on different architectures. For example, the following code on a machine (64-bit) does not throw any warning: 

  Size_t size = 1; Printf ("size is% ld", size);

But the above code on my other machine (32-bit) generates the following warning message:

WARNING: Expecting format '% ld' Long intestine ', but type' size_t * 'in logic 3

I suspect that this indicator is due to the difference in size, so that my 64-bit machine size_t is placed in long intervals ( "% ld" ), while my 32-bit machine is aliased for the second type on size_t is .

P> Yes: Use the z length modifier: 

  size_t size = (four) of size; Printf ("size is% zd \ n", size is); // decimal size_tprintf ("size is% zx \ n", size is); // hex size_t

The other length modifiers available are hh (for char ), h < For Code> Short , L (for long ), ll ( for long time ), j (for intmax_t ), t (for ptrdiff_t ), and L See <§7.19.6.1 (7) of the C99 standard for ( for a long time )

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
