And you expect us to guess how this relates to your project? Please collect information properly, and show the actual lines of code and messages together, ensuring that you identify which line of code is marked with which error.

You could also look more closely at these messages and work out for yourself:

why the identifier 'CFIS_Main' is not recognised.
why you are using the variable 'MyInstFrm', when it has not been defined in the current compilation unit.
why the call to 'MyProjectName::For_Student_Details::GetForm()' has the wrong number of arguments.

Use one of the constructors as described here[^].

int x = (Int32) thisisObjectType is boxing, if the type is already checked ?

int x = (Int32) thisisObjectType is boxing, if the type is already checked ?

C++

if (thisisObjectType->GetType() == Int32::typeid) // declaration of thisisObjectType would be…   Object^ thisisObjectType
{
int x = (Int32) thisisObjectType; // will this be considered as boxing ? should this be replaced with TryParse ?
}

Why would you use TryParse() if it's already an integer, and why would you need a cast?

C++

The Method or Property VCFilter::get_UrlBehavior deprecated and nolonger implemented....

But in another system, without update, still its working fine...

when I create XML_Schema, DataSet by XML Codes, and I can access that DataSet in reports dataset tab... earlier it has worked for me...
Now its giving this error, while I try to access that from Report Data Menu,DataSet Tab...

And therefore I get confused for the above problem....Any right directions for me...

Thanks again... Thumbs Up | :thumbsup:

I just read on stackoverflow[^] that it is probably possible to use C++ CX in normal desktop app (NOT a WinRT app).
(To replace Managed C++ / C++ CLI, with better performance and simplicity)

I wonder, is there any article / blog describing the process? and some fun application of it??

Subject says "elements". Your statement says "string".

For a string you use null termination or the string length property (depending on what you mean by string.)

In standard C++ if you want to know a count of arguments passed then you need to provide a mechanism for doing that yourself. Just like if your printf format string doesn't match the args passed then it will go off the end. Thus the format string implicitly defines the count.

Not sure but in Managed C++ it might be an actual array so you should be able to get to the Length property.
