Thanks Maximilien,

I have tested that it works! Cool!

A further question, L"\n" or L"\r" or L"\t" has the same meaning and function in UNICODE compared with ANSI peers "\n" or "\r" or "\t"? Or we should use other terms to represent "\n", "\r" and "\t" meaning of ANSI in UNICODE?

George

Deal experts,

I have some doughts on DLLs.
1) who will load the dependent dll in windows?
2) Do we need to specify any thing in our library to help auto dependent library loading?
3) Does the application needs to specify anything about all dependency libraries?
4) If some loader is doing this job, how it will get the dependent libs information?
5) Does OS will do any job in this regard?
6) what are the data structures used for this automatic dependent libraries loading?

Please explain me the mystry behind this automatic dependent libraries loading in windows? who will do which job and what are datastructures?

thanks in advance,
Ravinder Are

In an exe/dll, there will be sections called Import address table, Import directory table etc which will be holding the information about the depended modules and the functions of it. The loader reads this information while loading the exe and loades the dependend modules. if you want learn more, study the structure of Portabel Executale( PE ). Here is a good article An In-Depth Look into the Win32 Portable Executable File Format[^]

AFAIK, CImage's save functionality doesn't support appending pages to a TIFF fle.
You'll need to go directly to GDI+ to save the images.

This article, and the code within, may help:
Save images into a multi-page TIFF file or add images to an existing TIFF file[^]

If not, I can throw together example code for you.

or better yet, use the generic char types (TCHAR) and your code will compile for
both Unicode and non-Unicode builds.

Using Generic Text Mappings[^]

_tstoi() is the generic char function for atoi().

Why deque does not provide capacity and reserve function?

Only vector and string have capacity() and reserve() capabilities as they guarantee contiguous storage. deque doesn't.

How to convert CString to WCHAR*?

Hi,

I need to convert CString to WCHAR* but I don't know how.
If you know how please tell me.

Your comment will be a big help.
Thank you.

If your app is UNICODE enabled then CString can be used at the place of WCHAR* by using its str.GetBuffer() function.
If not then use MultiByteToWideChar() function to convert CString to WCHAR*

In addition to ccpptrain's reply...

If your app is UNICODE enabled then CString has a casting operator so you can use the string anywhere a
const WCHAR* is expected...without having to use GetBuffer().
