here is a script i find I hope it will be useful for u
#property show_inputs #import "user32.dll" int GetParent(int hWnd); int SendMessageA(int hWnd, int Msg, int wParam, int lParam); #import #define WM_MDIACTIVATE 0x222 #define WM_MDIMAXIMIZE 0x0225 extern string symbol = "EURUSD"; int periods[9] = {PERIOD_MN1, PERIOD_W1, PERIOD_D1, PERIOD_H4, PERIOD_H1, PERIOD_M30, PERIOD_M15, PERIOD_M5, PERIOD_M1}; int Window.activate(int hwnd) { int p = GetParent(hwnd); SendMessageA(GetParent(p), WM_MDIACTIVATE, p, 0); } int Window.maximize(int hwnd) { int p = GetParent(hwnd); SendMessageA(GetParent(p), WM_MDIMAXIMIZE, p, 0); } int Window.getHandle(string symbol) { int i, hwnd; for (i=0; i<ArraySize(periods); i++) { hwnd = WindowHandle(symbol, periods[i]); if (hwnd != 0) break; } return (hwnd); } void start() { int hwnd = Window.getHandle(symbol); Window.activate(hwnd); Window.maximize(hwnd); }
I get this message "2011.02.15 15:50:26 Forex 4H HiLo GBPJPYSB,H4: dll calls are not allowed; 'user32.dll'-'GetParent'."
How do I enable dll calls?

Is it possible to select the time scale programatically? I appreciate that this could be done by having one chart open at each time scale but I don't want to do that it would be too cumbersome. I'd like to have just one chart open for a market and have my EA set the timescale on that as appropriate. Can it be done?
Thanks.

Hi all, in an effort to debug my EA, I would like for it to programatically take a screenshot of the current state of the chart whenever a trade is placed. I did some searching and found pretty much what I needed at https://www.mql5.com/en/articles/1534. I just have one remaining little issue - my EA is running on about 10 different charts at the same time and therefore I need to be able to programatically maximize the chart window where a trade has just taken place, before I take the screenshot. Would anyone have any idea how to do this... if it's possible?
Thanks!
Shawn
