Re: How to run a java script(json) from my vc++ code?

4-Jul-17 2:25

I need to create a 'input' parameter in method of my web service.

I am writing a VC++ program where I am calling my vb web service method, using http request(SOAP packet). While calling this web method, return SOAP packet tells me only 'out' parameter(being generated by web method). I digged on google, came to know that this 'input' parameter may be added by json, XML scripts...

There might be some java expert here, who can answer my question...

This is not a question for Java experts, you are talking about javascript which is completely different. You also need to provide better details of what your code is doing, and where the error occurs.

Hi
While trying to get a better understanding of my exceptions I down loaded the demo

"

Quote:
How a C++ compiler implements exception handling

Well first I feel very good the I spent $700 to get the intel C/C++ compiler

the demo had inline asm code and the Microsoft compiler only supports thunder 32 bit code

but intel supports _asm with X64 I changed the "E" register to "R"

Was able to build everything until the demo

I got a number of externs I paste just one example but I am sire they are all related to cout

Quote:
error LNK2019: unresolved external symbol "public: __cdecl std::_Lockit::_Lockit(int)" (??0_Lockit@std@@QEAA@H@Z) referenced in function "public: void __cdecl std::_Container_base12::_Orphan_all(void)" (?_Orphan_all@_Container_base12@std@@QEAAXXZ)
1>MyExcHandler.lib(myexchandler.obj) : error LNK2001: unresolved external symbol "public: __cdecl std::_Lockit::_Lockit(int)" (??0_Lockit@std@@QEAA@H@Z)

doing research seems the .lib msvcprtd or msvcprt.lib for release ( did a dumpbin on the lib)

I included in my library directories

however I am still getting externals

Richard MacCutchan2-Jul-17 21:58

2-Jul-17 21:58

If these externals are related to std::cout then they should automatically get resolved by the STL libraries, which generally get automatically included in your project. However, since you are using the Intel compiler, it may be that you need to include some extra libraries that Intel provides.

Are you absolutely sure you did the Linker >> Input >> Additional Dependencies right? That looks suspiciously like what it is telling you or it's static versus dynamic linking but that usually presents slightly different.

Thanks I had downloaded the sample code "How the compiler implements exception handling"

Seems like SEH is only use full for 32 bit code as the EXCEPTION_REGISTRATION handler pointer

is a DD 4 bytes and I am running a 64 bit project

No absolutely not,

That field should be defined as a PEXCEPTION_ROUTINE callback which will be quadword pointer on a 64 bit platform. Sounds like you are looking at some 32 bit instructions in your sample.

Thanks this is in regards to the exception I'm getting access violation it happens intermittently
When it does the Debbuger gets control and points to ntdll looking at the call stack doesn't point me back to anywhere in my code. I was looking for a really low level Exception handler that might catch it earlier.
The code for the SEH in all the examples I have seen has inline Assembler

However I do have the intel compiler which lets me use _asm for 64 bit code

Thanks

Hi,

The unresolved symbol std::_Lockit appears to be from the Microsoft implementation of checked iterators[^] in our STL implementation.

So this implies that you are #including the Microsoft STL headers and trying to link with the Intel Standard C++ Library[^].

Fix your broken #include and library paths.

Best Wishes,

I have a templated class that is based on string or wstring, and most things are easy as the basic_string contains sufficient operators and methods to manipulate the text. However, one thing I cannot get round is including character constants inside the template, as below:

C++

template <typename T>
class Tokenizer
{
    typedef typename T::size_type _Mysizt;
    T strText;
    T strFilter;
    
    _Mysizt offset;	// offset of the current substring (token)
    _Mysizt index;	// index to the next separator character, or npos if not found
    _Mysizt length;	// length of the current substring, or npos if the last one
    
    public:
    Tokenizer(T strText, T strFilter)
    {
        // code removed for readability
    }
    
    T Next(bool bTrim)
    {
        T strToken;
        if (bTrim)
        {
            // trim leading spaces
// but ' ' will not be accepted for a wstring, and L' ' will not be for a string
            offset = strText.find_first_not_of(' ', offset);
        }
        // code removed for readability
    }
    return strToken;
}

I am sure it must be possible (OG, Po'H, SB), but my reading of the documentation and samples has not helped. So what (obvious) did I miss?

[edit]
While David Crow's suggestion works for a character constant, it will not work for a string like:

C++

offset = strText.find_first_not_of(" \t", offset);

I'm not sure I entirely understand the problem so my suggestion may be as valuable as a $3 bill. Can you use:

offset = strText.find_first_not_of(0x20, offset);

Or could you add the "search for" character as part of the constructor?

Richard MacCutchan2-Jul-17 21:55

2-Jul-17 21:55

Thanks, that did work, and your suggestion about the constructor I already tried. However, I am still wondering if there is any way to include string or character literals in such a template.

Presumably your goal is to use a set of characters rather than one character for your separator.
And the classes in use do not provide that functionality.

I believe tokenizers iterate through the string character by character, perhaps for efficiency and perhaps to avoid the problem you have.

If you want to avoid iteration then perhaps strtok() might solve it.
