View 2 RepliesCurrently using VS2008, VB.NET, SQL. I have a FormView from a Data Source that is getting some fields that are stored as Decimals in the SQL Database.
I am grabbing the field from the FormView as such:
Dim AvgTicketL As Label = CType(frmMerchantProfile.FindControl("F10Label"), Label)
I need to take this value, and convert it to an Integer, then send it along to an API. I have the API Calls done, tested and working, but I'm getting an error as when it is getting this value, the API is returning "Must be an Integer" error.
What I have tried so far:
Dim AvgTicketL As Label = CType(frmMerchantProfile.FindControl("F10Label"), Label)
Dim AvgTicket1 As Integer
AvgTicket1 = Double.Parse(AvgTicket.Text)
Do something with AvgTicket1
I have also attempted to Round the Value, then convert it and call it - no luck.
Checking the value of AvgTicket1 (Writing it out to a Label or Response.Write) shows "100", where the database value was 100.00. But the API is still getting 100.00, apparently. Any other conversion method that I've attempted states errors that the Label cannot be converted to Integer.
What are some methods I can successfully convert this value to an integer from a label?
When I try to run the following code it always spits out the hex representation, not the integer representation. Most of the examples I found on MSDN said this should work. What am I missing?
var stringBuilder = new StringBuilder("8");
int j = 0;
foreach (char item in stringBuilder.ToString())
{
j = Convert.ToInt32(item); //returns 38, need return to be 56
}
edit I should have made clear that I know the difference it's returning the hex value. I'm outputting the value to a file, and in that file, it still shows the hex value, not the integer, so I don't think it has anything to do with the debugging environment. edit2 Looks like a PEBKAC problem. Looked at the code that was writing to the file, and it was using a .toString("X") method, changing it to a Hex value. The fact that it was hex in my debug environment was what confused me.
int no = int.Parse(hidden_field.Value.TrimStart()); it cause the error: input format was not in correct format. how to fix it?
View 5 RepliesI'm trying to add a parameter at the end of a url obtained from the database as follows:
This is giving error because of the ID value, which is an integer...how can I convert it to string here? I can do it in code behind, but I just want to know how it can be done within the Eval function...

I have a stringvariabel in a form I shall insert in a SQL database in a integer field. I try to convert it in the parameterlist:
myComm.Parameters.Add("@UtstyrID",
SqlDbType.Int).Value =
Convert.ToInt32(e.Record["UtstyrID)"]);
but it only store the value 0 and not the value of the e.Record["UtstyrID)"])
I have the following code reading in my xml file and sorting it by ID:
Dim ds As New DataSet
ds.ReadXml(Server.MapPath("/posts.xml"))
Dim dv As New DataView(ds.Tables(0))
dv.Sort = "id desc"
The only problem is that it isn't sorting it numerically (it's sorting it alphabetically 1, 10, 11, 2, 24, 3, 4...). It appears as though I have to convert that column into integers, but I haven't been able to figure out an efficient way to do that.
im ds As New DataSet
ds.ReadXml(Server.MapPath("/App_Data/posts.xml"))
'ds.Tables(0).Columns(0).DataType = TypeOf(Decimal)
Dim dv As New DataView(ds.Tables(0))
'dv.Sort = "date"

I used below code to showing date in persian format
DateTime miladi = DateTime.Now;
System.Globalization.PersianCalendar shamsi = new System.Globalization.PersianCalendar();
Lbldate.Text = string.Format("{0}/{1}/{2}", shamsi.GetYear(miladi), shamsi.GetMonth(miladi), shamsi.GetDayOfMonth(miladi));
AND
public string miladitoshamsi(object miladi1)
{
DateTime miladi = Convert.ToDateTime(miladi1);
System.Globalization.PersianCalendar shamsi = new System.Globalization.PersianCalendar();
return string.Format("{0}/{1}/{2}", shamsi.GetYear(miladi), shamsi.GetMonth(miladi), shamsi.GetDayOfMonth(miladi));
}
and I have lable that I want bind it from database to show date so I wrote below code
lbldateM.Text = System.Convert.ToDateTime(miladitoshamsi(_dr1["date"])).ToString(" yyyy/MM/dd");
but below error happen

I have an integer field in my database that contains a date value in the form yyyyMMdd. Is it possible to parse this as a date in the form dd/MM/yyyy as bound to a datagrid?
Currently the field is bound like this:

I have a web page that has a textbox for users to enter a datestring to check against a database. The database that I am running my query against has datetime values set at minutes since 12/31/1899 and that returns a timestamp. What I'd like to do in my code is to convert my textbox entry into minutes since 12/31/1899. Does anyone have an easy way to do that?

it is giving the error message...
I applied this regular expression:

I've created a new vs.net project and added all the files from an asp.net website project.
When I compile, it couldn't find a reference to a class.
In the AppCode the class was defined, but without a namespace.
So I added a namespace, and then on the default.aspx.cs (this is where the error was originating) I added the using statement.
The using statement was not picking up the namespace.
I have this example and it gives me exception "Conversion from string x to dateTime is invalid"
here is my method to validate Datetime.
Example Date string : "27/03/1985"
Public Function validateDateColumn(ByRef FieldName As String) As Boolean
Try
If IsDate(FieldName) Then
Dim actualDate As DateTime = CDate(FieldName)
Dim DtLicExp As DateTime = CDate(actualDate.ToString("d", Thread.CurrentThread.CurrentCulture))
FieldName = DtLicExp.ToString("MM/dd/yyyy")
Return True
End If
Catch ex As Exception
'FieldName &= "Format must be MM/dd/yyyy"
Return False
End Try
End Function
validate this date string formate to datetime.
I want to convert this date "27/03/1985" to datetime.
I have searched a few pages on this (including MSDN) but have not quite reached a solution. I need to convert "16/04/2010 22:39:06" to "2010-04-16 22:39:06.034" (for example).
I have already written an SQL function to do this, but would rather do this in VB.NET if possible. The date value is coming from the Date Created information of a newly uploaded file:
