cursor problem

[Lost User]

Your function is defined as LoadCursor, but somewhere in your code you are trying to call LoadCursorW. This is probably due to the fact that LoadCursor is defined in Winuser.h as described in http://msdn.microsoft.com/en-us/library/windows/desktop/ms648391(v=vs.85).aspx[^]. Try changing your function name to something else, or use a namespace to avoid conflicts.

thank you very much Richard :thumbsup:

I changed the name of the function and I have no error but my cursor does not appear you have an idea please

LoadCursor just loads the resource, it doesn't change the system cursor to that shape. We'd need to see your code where you try to use the cursor. For example, do you use it: * In response to a WM_SETCURSOR message? * In a direct call to SetCursor()? * Passed to RegisterClass? John

Since your code does not do anything (as far as we can see) it's difficult to answer that question. What is this function supposed to do?

Hello thank you for your help.I have 4 function. Term.h

bool stateCursor; // Clignote du curseur
void CreateCursor(PaintEA e);

Term.cpp

void Term::CreateCursor(PaintEA e){

SolidBrush^ blackBrush = gcnew SolidBrush( Color::Black );
SolidBrush^ redBrush = gcnew SolidBrush( Color::Red );

if(CurPointCurrent!=CurPointPrevious) {

	int deltaX=CurPointCurrent.X-CurPointPrevious.X;
	int deltaY=CurPointCurrent.Y-CurPointPrevious.Y;
	float distance= sqrt(pow((float)deltaX,2)+pow((float)deltaY,2));
	float vectorX=deltaX/distance\*polygoneLength;
	float vectorY=deltaY/distance\*polygoneLength;
	// Creation des points de polygone 
	Point point1 = Point(CurPointCurrent.X+vectorX,CurPointCurrent.Y+vectorY);
	Point point2 = Point(CurPointCurrent.X+vectorX\*-0.866-vectorY\*0.5,CurPointCurrent.Y+vectorX\*0.5+vectorY\*-0.866);
	Point point3 = CurPointCurrent;
	Point point4 = Point(CurPointCurrent.X+vectorX\*-0.866-vectorY\*-0.5,CurPointCurrent.Y+vectorX\*-0.5+vectorY\*-0.866);

	// Dessine (clignoter noir <-> rouge)
	array^ curvePoints = {point1,point2,point3,point4};
	if(stateCursor==false) {
			e->Graphics->FillPolygon( blackBrush , curvePoints );
			stateCursor=true;
	}
	else {
			e->Graphics->FillPolygon( redBrush, curvePoints );
			stateCursor=false;
		}

}
else{
if(stateCursor==false) {
e->Graphics->FillEllipse( blackBrush , CurPointCurrent.X-circleRadius,CurPointCurrent.Y-circleRadius,circleRadius*2,circleRadius*2);
stateCursor=true;
}
else {
e->Graphics->FillEllipse( redBrush , CurPointCurrent.X-circleRadius,CurPointCurrent.Y-circleRadius,circleRadius*2,circleRadius*2 );
stateCursor=false;
}
}
}

FormD.h

private: System::Void picB_MainMap_Paint(System::Object^ sender, System::Windows::Forms::PaintEventArgs^ e) {

if(!first\_time) {
	ptr\_Term->CreateCursor(e);
}

}

private: System::Void picB_SubZone_Paint(System::Object^ sender, System::Windows::Forms::PaintEventArgs^ e) {

if(!first_time) {

ptr\_Term->CreateCursor(e);

}
}

Thanks

Sorry, I don't understand what you are trying to illustrate.

[neterfari]

sorry my english is very bad. I tried to create a cursor. I have a function that nominated CreateCursor in Term.h and Term.cpp and I call this function in FormD.h but not display the cursor

I am still not clear what you are trying to do, but you may need to read http://msdn.microsoft.com/en-us/library/system.windows.forms.cursor(v=vs.110).aspx[^].

thank you very much for your help Richard.:rose:I found the error, and my program works. error is not in the code that I've written here :)
