How to Close Modal Dlg from Constructor? [message #18371]

Hi,
I am trying to make a "Wait a moment, please..." dlg that is shown while computation is running. When computation finish the dlg must be closed automatically.
So, I used a modal dlg and in the contructor i have the following code:

ConstructorMethod
{
...
executeAlgorithm();
Close();
}

But the dlg never closes... As it as a close button if I click it the dlg closes.

Any ideas?

Alex

Too little to comment... Testcase?

Do you use "Open"?

LancaAnuids.h

#ifndef _CLancaAnuidsDlg_h
#define _CLancaAnuidsDlg_h

#include <CtrlLib/CtrlLib.h>
#include "Main.h"
using namespace Upp;

#define LAYOUTFILE <Main/LancaAnuids.lay>
#include <CtrlCore/lay.h>

class CLancaAnuidsDlg : public WithLancaLayout<TopWindow>
{
public:
typedef CLancaAnuidsDlg CLASSNAME;
CLancaAnuidsDlg();

private:
void Lanca(void);
};

#endif

LancaAnuids.cpp

#include "LancaAnuids.h"
CLancaAnuidsDlg::CLancaAnuidsDlg()
{
CtrlLayout(*this, Ctrl::GetAppName());

Lanca();

Close();
}

void CLancaAnuidsDlg::Lanca(void)
{
//Database intensive operations here...
}

On Main dlg I do:

void Main::LancaAnuidades(void)
{
CLancaAnuidsDlg dlg;
dlg.Run(true);
}

The dlg just has a static box saying:

Wait a moment please...

Thanks

Alex

Ah, this one is obvious:)

Dialog gets opened (and closed) in modal loop of "Run". Means your Close is basically NOP, because it is not opened yet.

What you need to do is to Open, Lance, Close. No modal loop.

I recommend seeing ProgressIndicator code....

Yes, I also thought that and thought to put a timer on contructor and after 2 seconds call the close but it is not a good fix...

CtrlLib/Progress

BTW, I guess maybe Progress is what you really need....

Progress pi("Working");
for(int i = 0; i < 100; i++) {
    if(pi.StepCanceled()) {
       Exclamation("Interrupted by user");
       return;
    }
    Sleep(500);
}
