Setup the request, works.

Hello Andy,

What programming language are you using? What are the arguments you passed to the getBar function call?

Here is a VB code snippet:

Dim lNumBars As Double
Dim j As Long
Dim baritem As IESignal.BarData

'Find out how many bars were returned
lNumBars = esignal.GetNumBars(historyHandle)

'Set the above number to its inverse for a decremented loop
lNumBars = lNumBars * -1

For j = lNumBars + 1 To 0

'Retrieve the BarData data structure
baritem = esignal.GetBar(historyHandle, j)
...
...

I am using a language called clarion, I am going to switch to a different language...

the tic feed will run for 20-30 minutes then hang and crash, so it isn't stable with that language.

have you or know someone that uses C# on it?

Hello Andy,

Visual Basic is the most commonly used language for the eSignal Desktop API.

You might want to consult with other forum users for their feedback and experience with C#.

I've done some work with the API using C#. No problems to report.

would you mind sharing some example code?

I am using sharp developer and it has issues with references, now I just downloaded the new MS C# developer but working through it...

I am a newbie with C#, but made a rule years ago to avoid VB<g> so off I go..

There is an old C# example in the File Sharing section...

http://share.esignal.com/groupgo.jsp?groupid=185

Specifically the poorly named Multiple History Requests in VB.zip. I'm not sure why I tagged "VB" at the end of the file name, other than I had been messing with VB samples as well at the time.

Cheers... George

brought it down and installed, changed the quotes to match the forex I wanted, no data.

either the event is not firing or no data is getting done.
