I've been running into some errors with converting strings to dates in the following code. I have recently added the intcall.Value = DateTime.Parse(txtIntCallDate.Text) function which had gotten rid of the error message, however the records are not being updated, any of them on the form. Prior to this the strings were being updated just fine. As long as there is a date entered on the form there is no error, if it's left blank i get the "Problem converting string to datetime"
I am writing a little program that does the following:Allows the user to enter a id number.Then when the find button is clicked, we connect to the database and run a select statement for the id.I am trying to figure out how to get the first name, last name and birthdate into textboxes on my form.
I would like to have a way to display a messagebox if the resultset = 0 so as to tell the user no records found.Then if the information is correct I am going to have a button to update the information which is going to call a stored procedure I have in place to update the record.how to make the connection which I think I have working and then loading the individual fields into the appropriate textboxes.
I'm creating a text file from values stored in a database. The text file output must contain a first and last name column. I'm having an issue parsing the suffix value from the name fields. Some of the first name values contain a suffix. I need to parse the first name column and move the suffix to the last name column if one exist. Can someone assist with moving the suffix from the first name column and appending to the last column?
I have a few date fields on a form. no matter what i've tried in the properties, the form still loads and there is a default date in there, how do you get rid of this?
Right now I have an array that is unparsed. One of its elements goes something like this:
"Blah, 555-5555"
So it's a name and a telephone number separated by a comma. The instructions I have tell me to use a query to put the information in the array into a data grid view in two columns, one for the name and one for the telephone number. I don't know how to isolate each inside a query.

Folks this is what I'm using to parse an RSS feed for the last updated time. Is there a quicker way? Speed seems to be a bit slow on it as it pulls down the entire feed before parsing.
I have a web app with a form that I am trying to pass to an ASP.NET server (using VB.NET) and then on to a MS SQL Server table. The form uses a jQuery datepicker in several textboxes and formats them as MM/dd/yyyy. The form fields are then passed through a PageMethod to the web server which takes the various field values and combines them into a SQL UPDATE command.
I am constantly getting the following error whenever I try to execute the SQL command:Conversion failed when converting date and/or time from character string.Here is the code on the server:
Using myConn As New System.Data.SqlClient.SqlConnection(CString.ConnectionString) myConn.Open() Dim cmd As New System.Data.SqlClient.SqlCommand("UPDATE table " & _
[code]....
Note: I've tried about twenty different ways of parsing the dates, converting them to dates, changing around the formats and none of it has worked.
Note 2: The conditional statements at the end are simply to prevent empty date fields from being stored in the SQL DB as "1/1/1900", but rather as an actual SQL NULL value. From debugging though, it seems that this is not the issue - it is when there is an actual value that the error is fired.

I have a problem in updating statements, can't write it correctly, every time I try to edit it, gives me different error (ora-01036 illegal variable name/number, missing expression, invalid identifier).
The following error is reported on attempting to update a record "Error parsing Update Query [Token line number = 1, Token line ofset = 38, Token in error = / ]". There is no "/" in the query. Here is the code:
This is the button Save code: Private Sub btnSave_Click(ByVal
Is there a way to do so? Say sometimes I see March 2nd, 1921
Latter I see 2 March 2010.Is there a function GetDate(SomeString as string) as Date?That will sort of recoqnize all those different format and "try" parsing.
I'm trying the fetch only the date within the current and return how many rows Dim dc as new dataclassesdatacontext dim q=from p in dc.worktime where p.name.equals(session("name") and p.date ).count what I should I put after "p.date" ? And if I want to search for the record which there are record that are insert five days earlier, how to do that ? use (datetime.now - 5) ?
experience on how to create an engine using C# (VB.NET is okay too) that is generic enough to handle most cases of MS Word text fields I need to fill with data I'm getting from a database? In short, I'm about to embark on this little Office automation excursion and I'm hoping a little bit of feedback here.
i have a table named item_details.i have some field named item_id,item_name,quantity,supplier_name etc.i want to see all details as per the item_id given in a textbox.i also want to see details as per the item_name is given.i can use 2 forms to view this type of query..one for item_id..and other to view from item_name.but..i want to use tabcontrol..in 1 tab i want go give the item_name...and want to get the details.and other tab i want to give the item_id...and want to get the details....and whenever i gave wrong information.an error message will be shown.
I have 2 Textboxes with Date/Time in them. I want to test if one is less than the other, here is my current code
Dim StartTime1TextBox As TextBox = TryCast(FormView1.FindControl("StartTime1TextBox"), TextBox) Dim EndTime1TextBox As TextBox = TryCast(FormView1.FindControl("EndTime1TextBox"), TextBox) If Not [String].IsNullOrEmpty(StartTime1TextBox.Text) Then
[code]....
However if I enter an Start time of 9:00 AM and an End Time of 5:00 PM this triggers the isvalid=false because 5 is less than 9. Doesn't look like it's comparing the date and time just number.
I am getting the above error in my code. I've searched the net (on this site and others) for a solution to this problem and it seems that its either something to do with a field name being a reserved name ie. Date, Time etc.... or its missing (') or (") in the SQL command. ive tried both these solutions to no avail.

I have a bindingsource question, didn't know if anyone had run into this before, but,there are several textboxes I put on a form, the text of each textbox is bound to a field in a table from the bindingsource. Why is it when I update the tableadapter, some of the fields update and some of them don't?
Example: using the bindingsource Textbox1.Text is bound to UnitListBindingSource - UnitNumber
i am making a simple testing application within visual studio 2010, thought im gonna be direct. in ms.acces i made a database with a few tables, this one is about the table : leden. the error indicates that i simply do not have enough values to insert into the table and i think it has to do with the ID(autincrement in acces)
My LINQ query contains the following Group By statement:
Group p By Key = New With { _ .Latitude = p.Address.GeoLocations.FirstOrDefault(Function(g) New String() {"ADDRESS", "POINT"}.Contains(g.Granularity)).Latitude, _ .Longitude = p.Address.GeoLocations.FirstOrDefault(Function(g) New String() {"ADDRESS", "POINT"}.Contains(g.Granularity)).Longitude}
The query works, but here is the SQL that the clause above produces
SELECT [t6].[Latitude] FROM ( SELECT TOP (1) [t5].[Latitude]
[Code]....
but this produced an error: "A group by expression can only contain non-constant scalars that are comparable by the server."
I have a problem with unicode character, as i create a database in SQL Server 2005. I want to query from a table that criteria fields are contain unicode character i.e NVARCHAR.
e.g: SELECT * FROM tblMyTable WHERE MyField='ភាសាខ្មែរ'. But when i did like this all rows that contain Unicode Character always display. it doesn't fit to my criteria
