How Can I do regex for this?
I was read your post: "Export GridView to Excel in ASP.Net with Formatting using C#" and is very useful. That code works perfect. But I need create a new format for a specific column in my sheet before to export it. For example:My DataTable have a column with decimal numbers and I'm trying reduce the tenths for each number.I want this: 2,874444 ----> 2,87 for a specific range. In this case I need it for all numbers in the column 13 or well said for the Column called N in Excel. Only reduce two tenths.
I used:
xlWorkSheet.Range["N"+h,"N"+h].NumberFormat = "0.00";
And no works (h is for rows, N is the column. Into a foreach).
Some values are returning 2.0 but I need it to be 2.00 as this is a money value that is displayed to the web page.
I am doing:
Math.Round(value, 2);
Is there a way to force it to 2 numbers after the decimal?
i have to check if an input string is valid based on the given regular expression.. this is the regular expression.
(a(bb+aaa+((ab)*bb+(aba)*aa)(a+b)*) + (b(aa+bbb+((ba)*aa+(bab)*bb)(a+b)*)
+ is an OR
* is a LOOP, it is optional, it may be done as many as a user wants.
i've tried many ways to solve the problem that my professor gave me but my knowledge isn't that enough to solve this problem..
There may be an easier way, and if there is I'm all for it. However - my ASP.NET page has a TON of controls on it, and I've given them all ID's that start with underscore. I copied all the markup into Notepad++ and I'm trying to find a regular expression that will find everything but the controls and replace it with whitespace. that way I'll have a text file that has all my control names which I'll probably throw into Excel and do some string manipulation to add ".Text = " etc.
View 2 RepliesThis is slightly different to most questions regarding HTML tags in strings - I want to add HTML!
I'm using a WYSIWYG editor which produces some eratic results. What im looking to do is to check the string it produces and check whether there are any sentences that aren't wrapped in a <p></p> tag. Typical strings could be:
Example 1
<p>Hello, this is string 1</p>
But string two doesnt appear to be in a <p> tag.
Example 2
None of this text is in <p> tags.
Example 3
Single line of text, again not in a <p> tag.
Could this be done using a regular expression?
