    =A1+TIME(1,0,0)

Although, maybe this should be posted on Super User.

In cell A1, enter the time.&lt;br&gt;
In cell B2, enter `=A1+1/24`

This may help you as well.  This is a conditional statement that will fill the cell with a default date if it is empty but will subtract one hour if it is a valid date/time and put it into the cell.

    =IF((Sheet1!C4)=&quot;&quot;,DATE(1999,1,1),Sheet1!C4-TIME(1,0,0))

You can also substitute `TIME` with `DATE` to add or subtract a date or time. 

I&#39;m running VS2010 premium. One of my teammates has both the solution configuration drop-down (Debug, Release) AND the platform (Win32, x64) combo-boxes in his toolbar. I don&#39;t.

For a reference, I&#39;m hoping to see:

Instead, I only see the first combo-box. What do I need to configure to make the second one appear?

Is there a way in Javascript to define a function and immediately call it, in a way that allows it to be reused? 

I know you can do one-off anonymous functions:

    (function(i) {
        var product = i * i;
        console.log(product);
        // Can&#39;t recurse here because there&#39;s no (ECMA standard) way for the 
        // function to refer to itself
    }(2)); // logs 4

Or you can name a function then call it afterwards:

    function powers(i) {
        var product = i * i;
        console.log(i * i);
        if (product &lt; 1e6) { powers(product) };
    }

    powers(2); // Logs 4, 16, 256...

But is there a cleaner way of defining and calling a function in one go? Sort of like a hybrid of both examples?

Not being able to do this isn&#39;t preventing me from doing anything, but it feels like it would be a nice expressive way to write recursive functions or functions that need to be run on `$(document).ready()` but also later when situations change, etc.

I am using Apache POI API to getting values from an Excel file. 
Everything is working great except with cells containing formulas. In fact, the `cell.getStringCellValue()` is returning the formula used in the cell and not the value of the cell. 

I tried to use `evaluateFormulaCell()` method but it&#39;s not working because I am using GETPIVOTDATA Excel formula and this formula is not implemented in the API:

    Exception in thread &quot;main&quot; org.apache.poi.ss.formula.eval.NotImplementedException: Error evaluating cell Landscape!K11

Java POI : How to read Excel cell value and not the formula computing it?

I am trying to figure out how to write a Hyperlink inside a cell using EPPlus instead of the cell containing the link text. I need it to be recognized as a link and be clickable.

Any help is appreciated.

How to create a link inside a cell using EPPlus

Since Excel 2007, Microsoft has split the classical `.xls` format to several formats (in particular, `.xlsx`, `.xlsm`, `.xlsb`). I&#39;ve got no problem to understand the use and purpose of `.xlsx` format but I am still wondering whether we should use a `.xlsm` or a `.xlsb` format when creating a file containing some VBA.

Of course, you can find some topics on the web, for instance:

 - on [Microsoft answers forum](http://answers.microsoft.com/en-us/office/forum/office_2007-customize/personalxlsm-vs-personalxlsb/9e45d7e7-dd27-4541-aff7-6c9b830b4496)
 - on [Microsoft blog](http://blogs.office.com/b/microsoft-excel/archive/2006/07/20/671995.aspx) that was pointed in the previous link (yet I&#39;ve parsed until the 10&lt;sup&gt;th&lt;/sup&gt; page without finding a ref to `.xlsb`)
 - [this topic from another forum](http://www.pcreview.co.uk/forums/difference-betweem-xlsb-and-xlsm-t3299124.html)

What I&#39;ve understood from this last link is that `.xlsm` is some kind of XML format and thus, needed for custom ribbon tab.

Beyond the **conceptual** difference between the format (`.xlsm` is based on *XML* VS `.xlsb` is a *binary* file), is there any **practical** difference when using any of this file (apart from the ribbon customization)?  
Have you ever seen any real difference when using any of these formats?


When should the xlsm or xlsb formats be used?

I tried to load a ~30MB excel spreadsheet into R using the XLConnect package. 

This is what I wrote:

    wb &lt;- loadWorkbook(&quot;largespreadsheet.xlsx&quot;)

And after about 15 seconds, I got the following error: 

&gt; Error: OutOfMemoryError (Java): GC overhead limit exceeded.

Is this a limitation of the XLConnect package or is there a way to tweak my memory settings to allow for larger files? 

I appreciate any solutions/tips/advice. 

&quot;Out of Memory Error (Java)&quot; when using R and XLConnect package

E.g 

    A1:I
    A2:am
    A3:a
    A4:boy 

 
I want to merge them all to a single cell &quot;Iamaboy&quot;  
This example shows 4 cells merge into 1 cell however I have many cells (more than 100), I can&#39;t type them one by one using `A1 &amp; A2 &amp; A3 &amp; A4` what can I do?
