Asp.net - Parse A Date From A Textbox And Store It In A Date Variable?

Jan 3, 2012

I am trying to parse a date from a textbox and store it in a date variable

Dim enddt_2 As Date = Date.ParseExact(txtenddt.Text, "dd/MM/yyyy", System.Globalization.DateTimeFormatInfo.InvariantInfo) 'txtenddt.Text
expenddt_1 = enddt_2.AddDays(-1)
enddt = enddt_2.ToString("dd/MM/yyyy")

enddt is a Date variable and when i convert enddt_2 to a string i get the error as

Conversion from string "17/01/2012" to type 'Date' is not valid.

Let me clarify, if a value in textbox is 17/01/2012 than after parsing the value is changed to 01/17/2012 (my systems Region and Language are dd/MM/yyyy) in enddt_2 and when i try to convert to dd/MM/yyyy format and store into a date variable i get the above error. This error comes only for the dates after 12. i.e a date variable accepts a date in MM/dd/yyyy format.The dates before 12 work fine, i.e for all dates from 1 to 12 there is no error.How can i make enddt store the date in dd/MM/yyyy format.

Store The Location As A Variable?

Nov 7, 2009

I have a program where I open files and I store the location as a variable so I can reopen them later on. It works much like MS Word does, where it shows the names on the side and when I click it and open, it will open the file. Mine is a little different because it will store large numbers of file names in a list box because people are usually going to open folders full of files. The initial way I did it had the path name stored in a list box and it would open the file using that path. I decided it was a bad idea and I tried to use just the name of the file. However, I ran into a problem with the code that I was using.

Code:
If its checked, it will open the selected item from the list box instead.
If CheckBox1.Checked = True Then
'for all the indexes of the saved location record of array, if the selected item is found, then open that file
For counter = 0 To SavedLocations.GetUpperBound(0)

[code].....

So as you can see, what I have is it decides whether you opened from the list box or not. If it is not from the list box, it opens it up fine. It adds the information to the list box and stores some information in an array so I can access it later on. If it does open from the list box, then it will search for the file name in the array. If it finds it in the array, it will proceed to open the file using the directory. There is no else clause because it should be finding it 100% of the time.

The error I get is that parameter cannot be null. Filename2 never seems to get assigned, which means it's not finding the value in the array. I've tested and the value is in the array and the values are the same values.

.net - Store Data In One Variable Or Multiple?

Jan 30, 2010

I have a file which is opened and the bytes are loaded into a class.The file needs to be split into chunks, and there is a header which gives the locations and sizes of the chunks.Should I (upon opening the file) split the file into chunk sand store each chunk in an array of variables And then when I want to access the data in the chunks I just use the array.

or store all the chunks in one variable together and then when I need access to the chunks get the location and size of them and use that to find chunks each time I need to modify them.

Store Variable Values Between Forms?

My application sends information from Form1 to Form2 by means of a global variable on Form1 whose value is read by Form2.

This variable is basically used to tell Form2 what it has to do because it's value will change depending on different conditions.

All form2 is meant to do is load data from a database into DataSets which will "ported" to Form1 (the main form) for consumption. I use a Form for this rather than a class because there's a lot of data that will be loaded each time it's visible and I wanted[code]...

VS 2005 Store / Retrieve Variable Or Property?

Oct 27, 2009

In the application I'm documenting, sometimes a value is stored in a Public variable & other times it's passed to/from a Public Property which does nothing except store it in/retrieve it from a Private variable. (And in one memorable exception, the Public Property stored it in a Public variable-I'm almost certain that was an oversight by the original programmer though.)

I know that passing it to/from the Public Property has the potential for better validation, but if the Property doesn't actually do anything except store/retrieve it is there any benefit to declaring it as a Property? (Or maybe I should put that the other way around. Personally I'd declare them all as properties because that will allow adding validation later-but I'm not rewriting this, I'm just trying to document it and, in this case, trying to figure out why sometimes it's done as a property & sometimes as a Public variable.)
