Creating a form inside a DLL [message #33825]

i write plugin for Download Master and have one question: how can i correctly initialize a form without a WinMain? my code:
StatDialog.h:

#include <CtrlLib/CtrlLib.h>
#include "StatPlugin.h"

using namespace Upp;

#define LAYOUTFILE "StatPlugin.lay"
#include <CtrlCore/lay.h>

class CStatDialog : public WithStatDialog<TopWindow> {
public:
	void setLnk (CStats &ptr);
	void Cal_CallBack ();
	void CBtn_CallBack();
	CStatDialog ();
	typedef CStatDialog CLASSNAME;
private:
	CStats _statslnk;
};

the form is created and then deleted when it calls (in other class):

UPP::Ctrl::InitWin32(0);
UPP::AppInitEnvironment__();
CStatDialog dform = CStatDialog();
dform.setPtr(stats_obj);
dform.RunAppModal();
UPP::DeleteUsrLog();
UPP::AppExit__();

it works but when app closes (dll detach) i get message "heap leaks detected" (debug build).

ok, next question. how to create custom sorting function for column in arrayctrl?

int cmpv(const Value& row1, const Value& row2)
{
	if (pureValue (String(row1)) > pureValue (String(row2))) return 0; else return 1;
}

function works fine, but sorting the table does not:

ExampleTable.ColumnAt(2).Sorting(cmpv);

access violation in Upp::sAC_ColumnSort::operator()(const Upp::Value & a, const Upp::Value & b):

ExampleTable.ColumnAt(2).Sorting(FnValueOrder(cmpv));

any ideas, please.

The initialization of form is definitely not the problem.

However, the issue could be about how you have arranged for DLL. Do you use DLL_APP_MAIN?

I am sorry, but there is too many variable not quoted in your post.

I suggest you to provide some minimal testcase (one complete enough to compile and run).

question still relevant.
upd.: solved. sorting class from ArrayCtrl.cpp:

struct sAC_ColumnSort : public ValueOrder {
	bool              descending;
	const ValueOrder *order;
	int             (*cmp)(const Value& a, const Value& b);

	virtual bool operator()(const Value& a, const Value& b) const {
		return descending ? cmp ? (*cmp)(b, a) < 0 : (*order)(b, a)
		                  : cmp ? (*cmp)(a, b) < 0 : (*order)(a, b);
	}
};

cmp function must return a negative value if value1 > value2 and positive if value1 < value2. why not true/false??
