Hi Abhinav,

Qt is a cross-platform app development framework.. Here is the wiki link for it...

Right thanks!

Make sure you check their website to see if they mention anything about WCF.

Hi all,

I am using Enterprise Library for validation on fields on the form. I have a field for email, I want to validate it using REGEX Validator if email is entered into the field, or if the field is left blank, I do not want any validation to happen on it. Which validator do I have to use to both ALLOW Null and check if email is entered.

I hope this makes sense.

Thanks,

You can add more than one validator, or use a custom validator, self validator

If the blank rows are within the data, you can apply the auto filter within code to do this. It will leave you with the autofilter selectors on the sheet but it is the quickest method. Just record a macro of you doing the task and you will have the basis for the code.

i am exporting the data to excel and finally i get the blank row below the data. I want to hide those rows without iteration

If the rows are at the end, you can find the row of the last cell that contains any data. In VBA it looks like this

Dim lastCell As Range
Set lastCell = Range("A1").SpecialCells(xlCellTypeLastCell)

From that you can work your way up deleting the blank rows. It still uses iteration but there are fewer.

Are they just the normal blank rows you get in any Excel spreadsheet? Or do they actual contain something and is making your workbook file size huge?

Suppose i send 9 rows to excel through datatable class.
and the remaining 65000 are blank, i wanted to hide these blank rows

If you now where the data ends, you will be able to create a range object that starts from the last row and finishes at the end of the spreadsheet then set the hidden property to true. Something like rangeToHide.EntireRow.Hidden = true;

Hi,
I am working on Human Resources software and i want to include face and finger print recognition in it,
i have no idea how to go about it in c#.
pls I need help on what to do.
Thanks.

Unfortunately, .NET is unlikely to include Face Recognition until at least V17.4, when the tecnology is mature. For the moment, that means you must join the growing band of highly-skilled teams working on getting it working reliably in the first place. Start here[^], but be aware that a lot of this technology is still under development, so what you find will not be the latest cutting edge developments. (Companies seem to have an aversion to publishing promising development until they can get the patents in place, for some reason)
