[QUOTE="MrMosin, post: 389115, member: 89447"] Hello All, I'm a complete newbie on the mediaportal platform so sorry in advance :D. Now for my problem; I'm been building a small little plugin to basically read some information from an external system. I want the plugin to update every 5 minutes or so to refresh the data being read from the external system. I also want a clock displayed. I've been using the tutorial/wiki thing about developing plugins for mediaportal. It was very usefull. My plugin is running and visible in mediaportal. The problem consists of two parts; [LIST=1] [*]Update the list during a timer action. I've tried to do this on a button click but to no avail. The item isn't showing in the list. [*]Update a lable during a timer action. This label is somehow 'not found' (= null) when in the event handler for the timer action. [/LIST] The list is declared as follows; [CODE]<control> <description>listcontrol</description> <type>listcontrol</type> <id>3</id> <posX>50</posX> <posY>80</posY> <width>100</width> <height>100</height> <spinWidth>-</spinWidth> <spinHeight>-</spinHeight> <spinPosX>-</spinPosX> <spinPosY>-</spinPosY> <spinAlign>Left</spinAlign> <spinCanFocus>yes</spinCanFocus> <onleft>51</onleft> <onright>51</onright> <onup>2</onup> <ondown>2</ondown> <textcolor>ffffffff</textcolor> <textureFocus>-</textureFocus> <textureNoFocus>-</textureNoFocus> <textureUp>-</textureUp> <textureDown>-</textureDown> <textureHeight>21</textureHeight> <scrollbarbg>-</scrollbarbg> <scrollbartop>-</scrollbartop> <scrollbarbottom>-</scrollbarbottom> </control>[/CODE] Now in the code part, I've declared it like this; [HTML][SkinControlAttribute(3)] protected GUIListControl listView = null;[/HTML] The strange thing is that with this code; [CODE]protected override void OnPageLoad() { LogMessage("entering OnPageLoad()"); base.OnPageLoad(); try { LogMessage("showing wait cursor"); GUIWaitCursor.Show(); LogMessage("filling some test items"); listView.Clear(); int totalItems = 0; for (int i = 0; i < 5; i++) { GUIListItem newItem = new GUIListItem(); newItem.Label = "Label #" + i.ToString(); listView.Add(newItem); totalItems++; } LogMessage("Items loaded: " + totalItems); LogMessage("hiding wait cursor"); } catch (Exception ex) { LogError("Error occured while executing the OnPageLoad: ", ex); } GUIWaitCursor.Hide(); }[/CODE] I see 5 items in the list when the plugin shows. So at this point, the listcontrol is accessible. When I try and add an item on a button click like so; [CODE]protected override void OnClicked(int controlId, GUIControl control, MediaPortal.GUI.Library.Action.ActionType actionType) { base.OnClicked(controlId, control, actionType); // catch button click if (control == null) { LogMessage("The passed control is null"); } if (control == btnRefresh) { LogMessage("btnRefresh was clicked"); if (listCaption == null) { LogMessage("listCaption label is null, trying to grab it"); listCaption = new GUILabelControl(GetID); } listCaption.Label = "Button clicked @ " + DateTime.Now.ToString(); if (listView == null) { LogMessage("listView is null, trying to grab it"); listView = new GUIListControl(GetID); } LogMessage("adding a new item"); GUIListItem item = new GUIListItem(); item.Label = "Button clicked @ " + DateTime.Now.ToString(); listView.Add(item); } }[/CODE] No item is added. In the logs I can see that the label is not found and that it is retrieved. The the text is set but no update on the screen. Same for the list. I have the following questions 1) Do I have to call some update method or something on the main control? 2) Is there a special timer control provided by mediaportal which i can use? I'm now using system.windows.forms.timer but that gives me problems accessing the controls as well. Thanks for your replies! Ok small update; The list problem has been fixed. I'm now using a GUIFacadeControl with it's view property set to List. This works perfectly. What remains is why the label is not updating when I set new text to it? [/QUOTE]
