Thanks, here some parts of the code:

BitmapGUI::Draw(x1, y1, x2, y2)
{
DrawBitmap(bitmap, 0, 0, GetUserWidth() - 1, GetUserHeight() - 1, x1, y1, x2, y2, BMP_NORMALSCALED);
return (TRUE);
}

AddBitmap(id, dialog, name, flags, x, y)
{
dialog->AddUserArea(id, flags, x, y);
new(BitmapGUI, id, dialog, name);
}

MyDialog::CreateLayout()
{
SetTitle(PLUGIN_NAME); AddBitmap(MY_BITMAP2, this, "header.png", BFH_CENTER, 0, 0);
return (TRUE);
}

Does this solve the problem?

  
BitmapGUI::Draw(x1, y1, x2, y2)  
{  
  //to avoid blinking/flickering  
  OffScreenOn();  
  SetClippingRegion(x1,y1,x2,y2);  
  
  DrawBitmap(bitmap, 0, 0, GetUserWidth() - 1, GetUserHeight() - 1, x1, y1, x2, y2, BMP_NORMALSCALED);  
  return (TRUE);  
}

cheers,

I tried that code but same, after some seconds of resizing the windows with button pressed the bitmap just disapears, very weird.

Note I just realized:
If i add a button to add another bitmap
then when i have the bitmap disapearing problem, i execute that code, then I maximize the dialog and the bitmap appears again...Only maximizing it, not while resizing.
That helps to spot the problem?

I don't normally use AddUserArea() because I prefer to use resource files, but with res files you have to use AttachUserArea() to add a user area object to the dialog. Do you have to do the same after adding one in code?

I only use the AddUserArea and the DrawBitmap , i have no idea how is with res files yet.

Is there a way to update/refresh the dialog? I notice it only refresh/updates when maximinzing, not while dragin/resizing. That can be a start to try to fix the problem.
