TradeStation Dlls?

[Mike Trader]

Thx guys.

I think I can get what i want out of these.

If I compile the code as a DLL, hoe do I call it from my DLL?

I don't recall who did this one, a bit more complex however.

There were several samples posted up here, search on PROGRESS and you may find some.

I do have the code for it however, let me see if I can dig up a sample and post it here.

This one uses a new thread to open and display the progress bar, so it is sorta separate from your application and can process the progress bar even if the app is crunching data:

$Compile Exe
$Resource "PROG.PBR"
$Include "WIN32API.INC"
$Include "COMMCTRL.INC"

Global hIcon        As Long
Global hDlg         As Long

Global hInstance    As Long
Global g_hThread    As Long
Global g_FileSpec   As String

Global Cancel       As Long
Global g_lngInitThreadHandle As Long

Declare Sub UpdateProgress(Text As Asciiz)
Declare Function ProcessFile(FileSpec As String) As Long

Declare CallBack Function ThreadItemsProc() As Long
Declare CallBack Function DialogProc() As Long

%PROGRAM = 1024
%PROGRESS = %WM_USER + 902

Hello All,

Anyone else here using TradeStaion and writing DLLs for it? I would like to share ideas with you.

Currently I have got TS to call my DLL and execute some code. Now I want to create a Progress bar. TS displays a stocks movement in a series or bars on a chart. When I apply a study, TS starts with the first bar on the chart and crunches through my code and then goes to the next bar and does it all over again. Variables are carried over from bar to bar, but I will be calling my DLL hundreds of times.

I want to be able to create a progress bar on the first bar and send it the total number of bars and the number os bars crunched so far to get a progres bar. The problem is the progress bar will be called thousands of times.

Does anyone know of cut and paste code for a progress bar that can be called many times and remain up untill the last bar sends it a command to go away? Something simple that can compile to a DLL.
