DisplayPanel: but the panel don't appears

[gabino.alonso]

hello, this is my problem:

some times when my application is running for a few minuts, when I use the DisplayPanel function , the panel don´t appears at screen.

I capture the return result of the operation, but this is the result:

DISPLAY PANEL STATUS[0]: No error has occurred

but the pannel don´t appears.

An idea of the problem?

thanks

There is little to tell about this problems with so few details about it.

Is this a top level or a child panel? Can this panel be hidden below another one? Can you move it to a screen position where cennot be overlapped by other application panels? Is your application running when you find this problem or is it stoppd / hang?

Can you post a small sample that exhibits the problem?

hello again, sorry for not reply earlier, I've been away ...

This is my normal situation:

// PROGRAMA PRINCIPAL --------------------------------------------
int main (int argc, char *argv[]){
int duplicate,
conectdb;

char buffer[256];

// una sola instancia del programa en ejecución
CheckForDuplicateAppInstance (ACTIVATE_OTHER_INSTANCE, &duplicate);
if(duplicate) return(0);

// PANEL PRINCIPAL
if (InitCVIRTE (0, argv, 0) == 0)
return -1; /* out of memory */

if ((panelPrincipal = LoadPanel (0, "cpm1201.uir", PANEL)) < 0)
return -1;
if ((panelLogs = LoadPanel (0, "cpm1201.uir", LOGPANEL)) < 0)
return -1;
if ((panelProd = LoadPanel (0, "cpm1201.uir", PRODPANEL)) < 0)
return -1;
if ((panLOGIN = LoadPanel (0, "cpm1201.uir", LOGINPANEL)) < 0) // this is a problematic panel >> Hiden by default 
return -1;
if ((panLOGIN2 = LoadPanel (0, "cpm1201.uir", LOGINPAN2)) < 0)
return -1;
if ((panADMIN = LoadPanel (0, "cpm1201.uir", ADMINPANEL)) < 0)
return -1;

... ...

When an user click on a button, a function launch the panel:

int LanzarPanel (void){ 

... ...

else{
... ...
RESULT = DisplayPanel (panLOGIN); // Panel Launcher
}

The first time, the panel not have a problem, always appears, 

Hide the panel with:  HidePanel (panLOGIN);

and the result is this:

The problem is that sudenly the panel don't appears but the retur of RESULT = DisplayPanel (panLOGIN); is DISPLAY PANEL STATUS[0]: No error has occurred

I don't have any idea what may be wrong by looking at your code, but looking at your use of panels, it may be more appropriate to use InstallPopup instead of DisplayPanel.

thanks for answering,

for the moment I try to solve the problem with DiscardPanel() instead of HidePanel()

and create it a new panel when I need it.

I hope that working correctly ... I need a few  tests more ...
