Please help me to figure this out. I am having two tab bar items in a tab bar application. First tab bar view with UITableView and second tab bar view with a label. I trying to pass table cell value to second tab view, by clicking a table cell and showing the value in the label of second tab view. The tab bar controller at the bottoms should be still visible. The main thing is I want the respective tab should be selected. I am using Xcode 4.3.2. This is something, will look like, I want to open a tab bar view from another tab bar view with a click of table cell. Thanks
Drag a line in the story boardfrom the tableviewcell (the cell!) to your view.
In
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
You get the destination controller like so:
if ([[segue identifier] isEqualToString:#"my_vc_1"]) {
MyViewController *detailViewController = [segue destinationViewController];
// here you can either reference the outlet directly
detailViewController.my_label.text = #"my value";
}
Don't forget to include your "MyViewController.h" on the top.

Hi the question is simple but i havent found the answer
Like here if i don't have the space to expand and want the user to be able to scroll left and right. Is this an option in PowerBi if so how? Up and down is auto
No scroll unfortunately, Jonas, in these cases I usually play with the indentations (Format -> Items -> Stepped layout indentation) and/or adjust the font. Splitting the slicer into several (year, month, etc.) and placing them under each other might also work.

I'm working with a QTableView and I want add a QComboBox in the 3rd column of every cell. There will be thousands of cells so I have opted for an in place editor solution. I want the combo box to be displayed when the user enters a cell by clicking or when the users uses the arrow key to select a cell in the 3rd column.
void FixtureCalibrationPage::on_View_clicked(const QModelIndex & index)
{
if(!index.isValid()) return;
if(index.column() != 3) return;
if(selected_table_row == index.row()) return;
if(selected_table_row != -1) { //clean up
ui.view->setIndexWidget(index, NULL);
}
selected_table_row = index.row();
ui.view->setIndexWidget(index, &m_combo_box_selection); //set the
}
Click does not cover the case of using a the arrow keys. Is my only option to manually check if the users pressed the Arrow key or does another solution already exists?
That's what delegates are for. Create a delegate object for the view and set it on the 3rd column by using setItemDelegateForColumn. Note that delegates must not be shared by multiple views. Each view needs its own delegate. It makes sense for the delegate to be a child of the view.
In your delegate, you will create the combo box in the implementation of createEditor method. You of course need to implement setEditorData, setModelData, etc.
Does anyone know how to add a new row (to add completely new data) to the TableView - directly to the control? Editing is quite easy, but how to add new data?
I thought this should not be a problem (as I know this from other prog. languages), but on the entire internet I have found only this one related topic posted a year ago which is not answered still. Is it imposible to do this in JavaFX?
JavaFX 2 TableView inserting rows directly on the control
Thank you very much.
TableView is backed by an items list, add a new entry to the items list and a row corresponding to the entry will be displayed in the TableView.
tableView.getItems().add(new Item());

I have a list with dates. If the dates are 3 months old, I need an email alert to users. This list needs to be automatically checked daily.
Is this possible out of the box with SharePoint 2010? Or am I looking at an out of box solution?
This is definitely possible with OOTB SharePoint 2010. You can use SharePoint Designer to accomplish this. Create a workflow that triggers when an item is created. Have it do the following actions:
Add 3 Months to My Date (Output to Variable: My Expiration Date) - "Add Time to Date" action
Pause until My Expiration Date - "Pause until Date" action
Email MyUsers - "Send an Email" action
This gets broken if My Date is updated because it will be using a invalid version of the Expiration Date. It gets trickier if you want to handle updates to the My Date field. That requires caching the value of My Date when the workflow starts and then running the following in parallel:
The Pause and Send actions from my example above
An action that waits for a change in My Date and kills the workflow if it is updated.
Basically what this does is to kill any previous workflow that was using an old version of My Date so that only the most recent one will send an email.

Is there a way to get a product's category from its UPC code?
For instance I want to use the upc code to determine if a food item is, frozen food, dairy bread, alcohol, etc...
Is there a web service that will do this?
The Wikipedia article doesn't say anything about UPC containing any product category number. The UPC just consists of a global manufacturer number and article number.
As upcdata.info categories are user-generated, not every product is contained in a category or products are categorized differently (e.g. "oregano" could be categorized as "spice", although there is a category "italian spices").
My approach to categorizing products by EAN/UPC:
I had the same problem, but instead trying to get low-quality category data from a web service I just pulled manufacturer information from GEPIR (which is the official registrar for EAN and GLN, also works with UPC numbers).
As I noticed that big companies like Nestlé, Procter&Gamble etc. have separate number ranges for different product (sub-)categories, I just try to identify those ranges and assign the appropriate category.
On the other hand, if I know that a manufacturer only has products of one category (e.g. spices), I can assign all products of that manufacturer to the "spices" category.
Despite of this automatic approach, there's still much work to do in order to get every product categorized intelligently.
Good luck!
You probably can make a quick mashup using: searchupc.com and upcdata.info and then retrieve product information from google product API.
Also, you can use AWSECommerceService API to retrieve something like this:
ItemLookupRequest request = new ItemLookupRequest();
request.getResponseGroup().add("Large");
request.setIdType("UPC"); // TODO: need to change if it's EAC
request.getItemId().add(upc);
request.setSearchIndex("All");
