How to determine a bad ticker

[jrthomas]

How can I determine a bad ticker string? It appears that GetRequestHistory() returns a valid handle even if I ask for a garbage ticker. I tried using GetGetTitle(), but it returns null for valid some tickers like 'w k8'.

thanks.

You can use the IsValidSymbol method. It returns 1 if the symbol is valid and 0 otherwise. Note that the symbol string you pass to this method must be in uppercase.

I got winsig.tlb from the C++ Example & I don't seem to have that function availible. Am I missing someting?

Its not in the docs I have either.

That method should be part of the eSignal hook object. Just like the way you would call IsEntitled().

[jrthomas]

Not working here. IsEntitled() works fine (and all the other functions do too):

bool b = (*m_piHooks)->GetIsEntitled();

but not:

bool b = (*m_piHooks)->IsValidSymbol(TickerName);

I get this error:

error C2039: 'IsValidSymbol' : is not a member of 'IHooks'

& like I said that function is not in "Esignal Developer Reference.doc" either, which found on this page:

btw, I'm using the C++. Could I have an old version of the winsig.tlb possibly?

[jrthomas]

OK, I figured it out. I have to import "winsig.exe" from the Esignal folder, not winsig.tlb as you C++ example does.

Is this documented anywhere?

Your winsig.tlb could be outdated. However, our C++ sample does indicate to import winsig.exe in stdafx.h. For future references, winsig.exe should be used.
