Converting String To Int?
Mar 10, 2010
i'm having a hard time figuring the way on converting my string into an integer number.In my form I have a textbox control from which I get the selected date as string, using the substring method I divide it to month, day and year.The problem is that I cannot, for example, convert the following "12" into the actual integer number twelve. I tried using Int32.Parse or Convert.ToInt32 but still couldn't solve it.Here's my code behind for better comprehension (this doesn't do the trick):

I am trying to figure out the best way to convert a string object into a DateTime with only using the year. I have something like:
[Code]....
But it is still giving a "String was not a recognized as a valid DateTime." In the full context, I have a webpage with a formview on it and within the formview is a TextBox control that is taking a user input such as "1999" then an ObjectDataSource picks it up and runs it through a BLL. And within the BLL is where I am trying to convert it before it gets inserted into the database.

I am looking for a way to design a simple HTML file, and in runtime - to load it as string to the c#.
I am trying to File.Open it, but it resides in a different location than the binary code.
is there a simple way to tell the build process to load it into a string?

I have an AJAX service where I'm pulling HTML content. I want to Response.Write() it to the browser as a string. I can't figure out how to do it so it remains a string like this rather than formatting the HTML:
<div id="global_nav">
<ul>
<li class="left"><a class="sub practice" href="/practice-time"><span>Practice Time</span>.
I've tried using HTTPUtility.HTMLDecode(string), but that doesn't appear to do anything.

I have a query that converts my string value I have stored in the database (nchar(8)). I have a stored procedure that gets the value and converts to date and when I run the select part of my stored proc to test it it successfully returns the mm/dd/yy format that I want: ex: 02/28/2010 However when I call this stored proc from my program I am getting an exception:
<Exception> Conversion failed when converting datetime from character string.
</Exception> Puzzled why the query works fine but .net gives me an exception? does anyone know how to solve this?
The part of my query that does this conversion is:

I have a maskededit extender
Code:
TargetControlID="dateTextBox"
Mask="99/99/9999 99:99"
MessageValidatorTip="true"
OnFocusCssClass="MaskedEditFocus"
OnInvalidCssClass="MaskedEditError"
MaskType="DateTime"
[Code] ....
So the input format looks like this 12/23/2012 12:12 AM
And I would like to convert this as datetime so i tried to do
Code:
Dim ab As DateTime
ab = DateTime.Parse(dateTextBox.Text)
But it's showing me an error
Code:
at System.DateTimeParse.Parse(String s, DateTimeFormatInfo dtfi, DateTimeStyles styles)
at System.DateTime.Parse(String s)
at admin_trackadd.saveButton_Click(Object sender, EventArgs e)

I have a field (varchar) field that holds date. Some data was transferred to this column but the transferred data was a timestamp (datetime in the format of say 10/26/2009 4:54:13 AM). Now, I need to modify the new table to only contain 10/26/2009. How can I write a statement to delete the time leavin gonly 10/26/2009? I can use trim function but the # of characters vary as the date might be 1/10/2010 12:50:00 PM, etc?

as part of a project I am working on, I need to output the alphabetical 'name' of the number. This is better illustrated with an example.960Nine Hundred and SixtySo it'd convert '960' to 'Nine Hundred and Sixty'. Is there an easy way to do this in C#.NET? Also, if so, how easy would it be to apply the same function to a decimal number? I'm assuming if I can figure out how to convert a integer as above, I can just split the decimal number... so I'd have something like this 960.23 Nine Hundred and Sixty (units) andTwenty Three (units)

Here is my code:
protected void SaveMyImage_Click(object sender, EventArgs e)
{
string imageUrl = Hidden1.Value;
string saveLocation = Server.MapPath("~/PictureUploads/whatever2.png") ;
[Code]....
The top imageUrl declartion is taking in a Base64 image string, and I want to convert it into an image. I think my set of code only works for images like "www.mysite.com/test.jpg" not for a Base64 string.

I have a detailsView whose date values in a cell are currently being displayed in longDateFormat, i want to convert all date values in this DetailsView to short date.
For example, instead of 6/1/2010 12:00:00 AM, i want to display just 6/1/2010
For a Gridview, i can achieve that by the code blow
Protected Sub DetailsView4_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles DetailsView4.DataBound
If e.Row.RowType = DataControlRowType.DataRow Then
For i As Integer = 0 To e.Row.Cells.Count - 1
Dim cellDate As Date
If Date.TryParse(e.Row.Cells(i).Text, cellDate) Then
e.Row.Cells(i).Text = String.Format("{0:d}", cellDate)
End If
Next
End If
End Sub
How can achieve the same with a DetailsView?

how I can get around the following error with the following code?
[Code]....
Error: Msg 8169, Level 16, State 2, Line 1 Conversion failed when converting from a character string to uniqueidentifier. As you can probably tell, the datatypes are: m.UserId = uniqueidentifier l.System_User_ID = varchar(256) I was hoping the casting of one to the other would solve the issue, but it doesn't. How can I re-code this? I see from other forums it would probably be best to set all these fields to uniqueidentifier, but would prefer not to at this stage as it will involve changing quite a bit throughout the whole site!
