How to Hide symbol chart's Caption and Border? Just like the picture:

I have tried import user32.dll and writed the code, but failed:

#import "user32.dll"

long SetWindowLongA(int hWnd, int nIndex, ulong dwNewLong);

long SetWindowLongW(int hWnd, int nIndex, ulong dwNewLong);

long GetWindowLongA(int hWnd, int nIndex);

long GetWindowLongW(int hWnd, int nIndex);

#import

int start()

{

.....

Print("GetWindowLong=====", GetWindowLongA(lChartWinHandle, -16)); // GWL_STYLE: -16. This Line prints correctly.

long ChartWinHandle = GetParent(WindowHandle(Symbol(), PERIOD_CURRENT));

SetWindowLongW(ChartWinHandle, -16, 0x2000000); // GWL_STYLE: -16. This Line makes MT4 crashed.

SetWindowLongW(ChartWinHandle, -16, GetWindowLongA(lChartWinHandle, -16)); // GWL_STYLE: -16. This Line print: stack damaged, check DLL function call.

....

}

I am in Win10 64-bit OS. MT4 bulid 1170.

So what the reason for it? Thanks a lot!

And btw, why does MT4 Crashed if i copy "user32.dll" into "..\MQL4\Libraries\" ?

Copy this code, paste it to a new Indicator, compile it.

Open any chart window, drop this indicator to the window.

By the way, you should not copy user32.dll anywhere. Leave it where it originally is.

if (iChartParent>0 && iNewStyle>0)

          SetWindowLongA(iChartParent, GWL_STYLE, iNewStyle);

You can't remove that thin border (at least I know no way to remove it)

but you can make it super-thin like the picture I posted (if yours is large) by adjusting the border size under Windows Display Settings -> Advanced -> Border (set to value=1)

remove all borders removing chart window border Interesting and Humour

Thank you bro, and follow your idea, i found the way in Win10:

1. Run regedit.exe

2. "HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics\"

3. Change "PaddedBorderWidth" to 0 (Maybe its default value is -60)

4. Reboot and Done.

Thank you bro :-)
