Tree control tag with keyboard

I'm using a tree control and navegating with the keyboard arroy. When a choose a specific tag, i do a double click and call for a subvi. I need do the same thing when i press Enter Key, but the event Key Down don't return the tag of the tree control like the event Double Click. There's a way to do this with the keyboard?
Thanks for the help.

You could simply read the tree control's value:

Can't control iTunes with keyboard after 10.5 update?

Hi everyone.
I run Win7 Ultimate x64 and have a Microsoft Wireless Laser Keyboard 6000 v.2
The keyboard has a row of buttons along the very top to control media players; play/pause, skip between tracks, etc.
Up until I updated to iTunes 10.5, I was able to use those buttons to pause and skip between tracks in iTunes, but iTunes didn't have to be my active window - I could be, say, composing this post with iTunes playing, but minimized to the task bar, an hit a keyboard button to pause or skip forward.
I can no longer do that - I now have to actually go to the iTunes window in order to control it, or hold my mouse over iTunes in the task bar and I get a little back/forward/pause button that I can use to skip.
In any case, this is extremely annoying and I'm wondering if anyone else has encountered this issue and if there are any workarounds.
Thanks

rageboy04,
For issues with third-party software (software not made by Apple in this case), that interacts with Apple software, I would recomend contacting the maker of that application.
Often with any application that controls another application, whether it is iTunes or anything else, when one is updated, the other needs to be updated as well.
Thank you,

Control surface with keyboard controller

I'm fairly new to Logic and sequencing (but not Macs) so I'm on a steep learning curve.
I set up Logic with a Yamaha 01x as an interface and control surface. That's working o.k (after some dramas). I play software synths with an Edirol PCR controller keyboard. What I want to do dedicate the 01x to sequencer and mixing duties and assign the keyboard knobs and sliders to soft synth controls, (preferably globally - as in not plug-in by plug-in). When I try to use the learn function on a soft synth it doesn't want to take the assignment. It flashes the name of the keyboard briefly then reverts back to the name of the 01x port. I'm thinking it has something to do with the fact the keyboard is a separate USB midi interface. Whatever it is, I don't know where to find a set-up page for the keyboard or the combination of the keyboard and the 01x. Funny thing is, setting up my keyboard is so easy in MainStage which is part of the same software suite.
I can't find anything in the manual that deals with this sort of hardware controller combination. Any help would be greatly appreciated.

I still can't get this working so I am posting some more information in case someone can see a glaring hole in my logic (pun definitely intended).
I have tried setting up controller assignments in both the Logic preferences and by the learn function within the plug-ins. My keyboard is a USB MIDI interface but it is not seen as a control surface by Logic. (As you say, Bee Jay, that's a good thing). It is sending out notes and controller messages on its own discrete port, port 1 (of two), channel 1. The synths in MainStage can see my keyboard and my control surface just fine. I can't see why it should be any different with Logic? Certain controllers always work (pitch bend, mod wheel pan volume and aftertouch). I have not been able to assign any of the other controls of any soft synth. Even if I set the soft synth destination to receive a source I know the keyboard is putting out (I can see it on the transport bar input display), it still doesn't work the control. I've tried deleting all "learned" controllers and starting again - Many times now.
Needless to say, I'm getting to that stage. . .

Control animation with keyboard

http://java.sun.com/products/java-media/2D/samples/suite/Image/DukeAnim-pi.html
Is there anyway that one could control the movement of something like this (the walking thing) with wasd or the arrows???

Controlling sliders with keyboard cursor

I don't know whether this is trivial or not but does anyone know how to control the sliders with the cursor keys? e.g. up-down cursor for up-down slider left-right for left-right slider.

Give the control focus (Using TAB key)
the SHIFT and arrow (UP)
Interestingly its the same for both sliders
(Ergonimic disaster or Windows native)?

Change the selection of tree control with a right click

How is it possible to change the item selected in a tree control (LabVIEW7) with a mouse right click ?

Filippo,
Here is a popup menu toolkit, with an additional example for a listbox. If I
understand your problem, it shouldn't be hard to change it to a tree
control.
Regards,
Wiebe.

Single click on tree control navigation

Hello I have a tree control where I have include the navigation, I know that there is a method
HANDLE_NODE_DOUBLE_CLICK FOR G_TREE
but is there an method for only one click, I want to change my alv grid data when I click on several nodes in my tree control

Hello Muhammet
I have re-written my sample report ZUS_SDN_TWO_ALV_GRIDS into ZUS_SDN_TREE_AND_GRID_CONTROL which is now display a tree control together with the ALV grid.
When you analyze this new report you will see that every step of the program logic is as I described in my previous e-mails.

How Stop Pop-Up Window: Allow Fullscreen With Keyboard Controls?

How can I cause the cessation of the pop-up window that asks me, "Allow fullscreen with keyboard controls?"
In the last month or two (January- February of 2013), this black, semi-transparent pop-up has appeared every time I go to full screen in the game Battle Pirates on facebook.
After numerous iterations, this confirmation request has become completely unneccessary and nothing more than an unwelcome annoyance.

Tom,
Moderators have the authority and privilege to mark answers as correct, in addition to the original posters. ANY moderator here could have marked it that way.
The Bug report/Feature Request link is not a "vote" page per say, but a place to submit a request for a feature you'd like to see added or dropped from Flash Player. It's the best way to voice a concern or "wish" for a feature, since the development team reads the reports/requests. Management who'd make the decision to add or remove something won't read about it here. They WILL hear about it from development.

How do I get the tag of a selected line in a tree control ?

I am running LabVIEW 7.1.
I want to be able to add a parent or sibling to a tree to a selected item in a tree.

The tag of the selected item is actually the output of the tree control itself. If you create an indicator from the tree control, you will get a duplicate tree control (indicator), but if you wire the output into a string indicator, the tag of the selected item will show up. You can an item to the tree by wiring the tree reference into an invoke node, calling the method "Edit Tree Items: Add Item", and wiring the output of the tree control (which will be the tag of the selected item) into the "Parent Tag" terminal. This method will only let you add a child to an item, you cannot add a parent or sibling. Items cannot have multiple parents, so it wouldn't make sense to add a parent; and to add a sibling for the selected item, you could call the method "Navigate Tree: Get Parent" and pass the tag of the parent into the "Edit Tree Items: Add Item" method.

Hi,
I have written code for 'Export To Excel' in the visual web part as below
//ascx file
<table>
<tr>
<td>From Date:</td>
<td><SharePoint:DateTimeControl ID="dtFromDate" runat="server" DateOnly="True" /></td>
</tr>
<tr>
<td>To Date:</td>
<td><SharePoint:DateTimeControl ID="dtToDate" runat="server" DateOnly="True" TimeOnly="False" /></td>
</tr>
<tr>
<td>Report Type:<asp:DropDownList ID="ddlreporttype" runat="server"><asp:ListItem>Consolidated</asp:ListItem><asp:ListItem>Question Wise</asp:ListItem></asp:DropDownList></td>
<td>
<br />
<asp:GridView ID="gvwikireport" runat="server">
</asp:GridView>
</td>
</tr>
<tr>
<td><asp:Button ID="btnExportToExcel" runat="server" Text="Export To Excel" OnClick="btnExportToExcel_Click"/></td>
</tr>
</table>
//cs file
protected void Page_Load(object sender, EventArgs e)
if (!Page.IsPostBack)
BindGridview();
private void BindGridview()
DataTable dt = new DataTable();
dt.Columns.Add("UserId", typeof(Int32));
dt.Columns.Add("UserName", typeof(string));
dt.Columns.Add("Education", typeof(string));
dt.Columns.Add("Location", typeof(string));
dt.Rows.Add(1, "SureshDasari", "B.Tech", "Chennai");
dt.Rows.Add(2, "MadhavSai", "MBA", "Nagpur");
dt.Rows.Add(3, "MaheshDasari", "B.Tech", "Nuzividu");
dt.Rows.Add(4, "Rohini", "MSC", "Chennai");
dt.Rows.Add(5, "Mahendra", "CA", "Guntur");
dt.Rows.Add(6, "Honey", "B.Tech", "Nagpur");
gvwikireport.DataSource = dt;
gvwikireport.DataBind();
protected void btnExportToExcel_Click(object sender, EventArgs e)
Page.Response.ClearContent();
Page.Response.Buffer = true;
Page.Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", "WikiReport.xls"));
Page.Response.ContentType = "application/ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
gvwikireport.AllowPaging = false;
BindGridview();
//Change the Header Row back to white color
gvwikireport.HeaderRow.Style.Add("background-color", "#FFFFFF");
//Applying stlye to gridview header cells
for (int i = 0; i < gvwikireport.HeaderRow.Cells.Count; i++)
gvwikireport.HeaderRow.Cells[i].Style.Add("background-color", "#df5015");
gvwikireport.RenderControl(htw);
Page.Response.Write(sw.ToString());
Page.Response.End();
But after clicking the 'Export To Excel' button i am getting the below error
Control 'ctl00_SPWebPartManager1_g_d4fb972b_26ec_4065_9c89_80b51b384492_gvwikireport' of type 'GridView' must be placed inside a form tag with runat=server.
In case if i am modifying the code as below I am getting error as 'page can have only one server tag'.
<form id="frmgrdview" runat="server">
<asp:GridView ID="gvwikireport" runat="server">
</asp:GridView></form>
So please share your ideas/thoughts on the same.

Hi,
According to your post, my understanding is that you fail to export to excel.
I create a demo as below, it works well.
<table>
<tr>
<td>
<asp:Label ID="Label1" runat="server" Text="Name"></asp:Label>
</td>
<td>
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td>
<asp:GridView ID="gvwikireport" runat="server">
</asp:GridView>
</td>
<td>
<br />
<asp:Button ID="btnExportToExcel" runat="server"
onclick="btnExportToExcel_Click" Text="Export to excel" />
</td>
</tr>
</table>

using System.Web.UI;
using System.Web.UI.WebControls;

dt.Columns.Add("Location", typeof(string));
dt.Rows.Add(1, "SureshDasari", "B.Tech", "Chennai");
dt.Rows.Add(2, "MadhavSai", "MBA", "Nagpur");
dt.Rows.Add(3, "MaheshDasari", "B.Tech", "Nuzividu");
dt.Rows.Add(4, "Rohini", "MSC", "Chennai");
dt.Rows.Add(5, "Mahendra", "CA", "Guntur");
dt.Rows.Add(6, "Honey", "B.Tech", "Nagpur");
gvwikireport.DataSource = dt;
gvwikireport.DataBind();
protected void btnExportToExcel_Click(object sender, EventArgs e)
Page.Response.ClearContent();
Page.Response.Buffer = true;
Page.Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", "WikiReport.xls"));

Report with Dynamic tree control

I have a report with a TREE CONTROL.
<p>
A Tree is referenced to: CL_GUI_ALV_TREE_SIMPLE and is located on the left side of the screen.
<p>
See diagram below. The Tree has MULTI-LEVEL nodes and the user can click on any of the nodes which will
trigger a report (rellevant for that node) to appear in the REPORT container.
<p>
Everythign is working fine.
<p>
I now have a requirement to add a TREE ON/OFF functionality. I have added this by 'Freeing' TREE
container and by initializing when the user Turns ON the TREE. It is working fine, HOWEVER, when
it initilizes the TREE it is COLLAPSED and obviously does not point to the NODE that was clicked.
<p>
My goal is to retain the value of the NODE that was pressed and EXPAND the tree to that node and
highlight it... Please note that I have MULTI-LEVEL nodes and the user can double click on NODES
and ITEMS.
<p>
I tried using GET_SELECTED_NODES, but it only works if the user selects the LOWEST level node/item.
<p>
Any advise will be appreciated.
<p>
Also, as an alternative, I was thinking of resizing TREE container to WIDTH of 1 when the user PRESSES
TREE OFF and resizing back to width 200 when the user presses TREE ON. I could not find any methods
that would work with CL_GUI_DOCKING_CONTAINER.
Please help! Thank you in advance.

Tree control with Nodes in ALV

Hi ABAP Gurus,
I am trying to create tree control with nodes in ALV. I have referred to standard BCALV_TREE* programs but new to OO programming. Not sure as to how I can display my internal table data than the SFLIGHT information in these programs. Can you please let me know how this can be done or if I can use any ALV function modules for the node display.
thanks,
Chaitanya

Maybe you could use this. Call this VI from a Value Change event of the tree.
