问题 Here is an image of what I want to do in CSS: image. Any ideas? 回答1: Initial issue Centering an element that has no explicit width This prevents the usual solution of margin: 0 auto; from being an option. Greater issue There's no unused space for centering the wrapper in its container An element is said to be shrink-wrapped if its width is determined by the width of its content. If the content changes in size, the width of the element changes likewise. This is the default behavior for

Should the EnumDataTypeAttribute work correctly in .NET 4.0 using Entity Framework?

I have an enumeration which I'd like to persist as a value of some sort into the underlying database so that I can bring it back and forth. I have read some articles that suggest to create a enumeration wrapper with static implicit operators defined, mapped using a ComplexType object mapping as described in the link below. How to fake Enums in EF4 This solution works flawlessly! My thanks to Alex James . Aside, I discovered of the EnumDataTypeAttribute Class which purpose seems to handle enums persistence through Entity Framework. I tried it and it doesn't seem to work at all. Here's a code

C++ to C Wrapper using SWIG (for FLTK)

阅读更多关于 C++ to C Wrapper using SWIG (for FLTK)

问题 I need to generate wrapper to FLTK C++ classes to use it in pure C. I know, that SWIG can do that, and I know how to generate wrapper for C#, Python etc. But I do not know how to wrap C++ to C using SWIG. It's simple task, but I can't find the answer :) Please, help. 回答1: I don't think SWIG supports generation of C wrappers out of the box. You always need to specify a target language. In 2008, there was a GSoC project to write a C backend, but that was apparently never completed/incorporated

Duplicate of Calling .NET methods from VB6 via COM visible DLL Which ways exist to use/call .NET classes/functions/libraries (.net 3.x) in VB6 or classical ASP ? Has anybody experiences with that ? How much effort is necessary to wrap .NET to COM ? Are there tools which help ? It's pretty easy actually and I have created .NET components called from both VB6 COM dlls and Classic ASP. You essentially need to create a COM callable wrapper thats exposes the .NET component to a COM client.

Wrapper question when containing floating divs

阅读更多关于 Wrapper question when containing floating divs

I would like to create a, browser centered, bordered, wrapper that autoexpands in height around various divs. When using floats to keep the divs in-line, the wrapper just stops after the first div. Be kind, this may or may not be right way to do this but that's why I'm here. Here is a simple example. <head> <style type="text/css"> <!-- #wrapper { height: 100%; width: 800px; border: 1px solid #000; margin-right: auto; margin-left: auto; } #header { height: 100px; width: 800px; } #column1 { width: 300px; height: 400px; float: left; } #column2 { height: 400px; width: 300px; float: left; } #navbox

what is equal to the c++ size_t in c#

阅读更多关于 what is equal to the c++ size_t in c#

I have a struct in c++: struct some_struct{ uchar* data; size_t size; } I want to pass it between manged(c#) and native(c++). What is the equivalent of size_t in C# ? P.S. I need an exact match in the size because any byte difference will results in huge problem while wrapping EDIT: Both native and manged code are under my full control ( I can edit whatever I want) There is no C# equivalent to size_t . The C# sizeof() operator always returns an int value regardless of platform, so technically the C# equivalent of size_t is int , but that's no help to you. (Note that Marshal.SizeOf() also

Why ambiguous error when using varargs overloading with primitive type and wrapper class? [duplicate]

阅读更多关于 Why ambiguous error when using varargs overloading with primitive type and wrapper class? [duplicate]

This question already has an answer here: Ambiguous varargs methods 4 answers I do not understand why here in case 1, it is not giving compilation error, contrary in case 2 (varargs), it gives compilation error. Can anyone please elaborate what differences the compiler makes in these two cases? I went through many posts about it, but not able to understand it yet. Case #1 public class Test { public void display(int a) { System.out.println("1"); } public void display(Integer a) { System.out.println("2"); } public static void main(String[] args) { new Test().display(0); } } The Output is: 1 Case
