Hi Thanks for the help,
continue is iterating the current loop but not the main (outer) for loop.
break will just break the current for loop but other loops following it will be executed.
The "goto" is working, if its standard way I want use it.

Thanks,
Suman

You can use also goto in the following manner.

:loop1 for() //main for loop
{
   for() //for loop1
     {
         if(condition)
         {
          //code
          goto Loop1;
      
         }
      }
   for() //for loop2
      {
      }
   for() //for loop3
      {
      }
}

Hi, Thanks for the help!!
Presently, I am using the "goto".
"goto" seems smarter than checking the same condition in all for loops and "break"ing from them.

With Thanks,

Did you mean "loop1: for()", the colon after label?

Not really. The goto statement should rarely be used. It could be used when your application is really time critical. In any other case you should try to use condition.

for() //main for loop
{
 for() //for loop1
 {
  if(condition)
  {
   //code
  }
 }
 if(!condition)
 {
  for() //for loop2
  {
  }
  for() //for loop3
  {
  }
 }  // end if(!condition)
}

Hello everyone,

skipws works for both char based and wchar_t based string stream? I have not found formal clarification from MSDN.

Did you try it ?

I would imagine that if nothing is said specific to that, it would be supported for all formats.

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?

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,

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 ).

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.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
