Hi Novo Thanks,

but

for a beginner, it is difficult to understand at first a reference to in-depth routines such as "DL"!
this topic of your link does not clarify much.

See after searching the forum, I also didn't get any practical example. So, only about 2 links commented on the "DL", then I made a comparison with some examples of Dll´s p / c ++ from the tutorialspoint, and even then, I hit my head, but in the end I got it wrong and tried it. I thank my guardian angel too!!!


..
//didn't have this component so I had to look for how to download...ide->menu Setup->UppHub  and select Functions4U
//in the declaration
#include <Functions4U/Functions4U.h> 
...
Dl screen;
void (*yF)(int x, int y, int cx, int cy, char *filename);
...
//AA is my class with method below
// integer n is saves lives 
//lifeguards that I had to adapt because
//the link https://www.ultimatepp.org/src$Functions4U$Dl$en-us.html 
//that exemplifies on windows will fail (bug?) if it [b]loads repeatedly[/b]

void AA::clickDll(){
	if(n==0){
		
	   if (!screen.Load(AppendFileName("C:\\Temp\\outU++\\NOVOXXX\\CLANGx64.Debug.Debug_Full.Gui", "CaptureScreenDll.dll")))
              throw Exc(Format(t_("% dll not found"), "Capture"));
	
           yF = (void (*)(int,int,int,int,char *))screen.GetFunction("capture_screen");
 
	}
        if (!yF)
           throw Exc(Format(t_("Function %s does not found in dll"), "captureScreen"));
 
        char* f="teste.png";
        yF(669,187,420,22,f);
     
        n++;

}
