I have tried using .NET's various encryption functions but all my encrypted strings are at least 24, 28 or 32 in length.
I have heard of CipherMode.CTS with Padding = None that produces the same length output as the input length but I can't seem to get the same result. I have toyed with the block-size, key-size and salt size.
I don't mind adding a digit to my input string to make it 16 in length.
Passing onto a stored procedure a value from a GridView. The particular fields are a date type, and numeric type. Problem is, its plausible and conceivable in this case one or both could be null or empty.
Through searching I've seen suggested such ideas as Convert.ToDate(value), CDate(value), and so on. None of these work. You cannot convert an empty string or null value to a date. I don't know about the numeric value.
So, barring any non-working examples already given. What is standard. Its not like I've stumbled across some never afore seen problem.
Here is my code, but its quite typical.
Dim txtctlHireDate As TextBox = CType(gvEvaluatees.Rows(e.RowIndex).FindControl("txtHireDate"), TextBox) Dim txtctlGradYear As TextBox = CType(gvEvaluatees.Rows(e.RowIndex).FindControl("txtGradYear"), TextBox) Dim txtctlBU As TextBox = CType(gvEvaluatees.Rows(e.RowIndex).FindControl("txtBU"), TextBox) Dim ddlctlEvalGroups As DropDownList = CType(gvEvaluatees.Rows(e.RowIndex).FindControl("ddlEvalGroupSelection"), DropDownList) Dim chkctlActive As CheckBox = CType(gvEvaluatees.Rows(e.RowIndex).FindControl("chkActive"), CheckBox) UpdateEvaluatees.MGEvalUpdateEvaluatee(gvEvaluatees.DataKeys(0).Value, txtctlHireDate.Text, txtctlGradYear.Text, txtctlBU.Text,ddlctlEvalGroups.SelectedValue, chkctlActive.Checked) gvEvaluatees.EditIndex = -1 gvEvaluatees.DataSource = EvaluateesForDataGrid.GetData gvEvaluatees.DataBind()
I've bolded the parameters in question. A date value and numeric value are expected.
I want to modify my userAvailabilityCheck code and want to add the code that this userAvailabilityCheck function does not fire If the textbox is null or having character less than 6 but display related error message.
Below is my code-
[Code]....
As you can see in the above code, I have added if else code in my working code but after the addition of these checkers my code stops working.
i have 100 words in paragraph now i want to make array which contain 10 words in each array slot but not break words mean "Hello" in one slot would be "hel" and in second slot rest of word "lo".
I'm using ASP.NET with sql-server. I have an area where the user can enter text of a maximum amount. I encode this text as a good measure but the encoded length can be greater than this maximum amount when I try to insert it into the database.
Special characters are encoded on 3 characters. I can't show the user that he has exceeded the max amount of characters because from his perspective he hasn't. I also can't set the database field to the worst case scenario (being 3 times my max amount).
I'm using the following code to get a list of sites from a database and then show a short extract from the posts. The number of posts shown and the length of the extract is defined in the appsettings of the web.config.

I get the following error:
Index and length must refer to a location within the string. Parameter name: length
I am exporting a HTML table to excel by sending the data as a HTML Table string and setting the content headers:
[code]....
Is there a simple way of setting the content-length based on the size of the HTML string? Or should I just leave it blank anyway...would be nice to have the content-length ideally...
I need to limit the length of the string that load into a DataTable that is being used to display. The data I am loading is coming from another DataTable. How do I shorten row["CG_GalleryName"] contents to 24 characters.
Convert.ToString(row["CG_GalleryName"]) -- how do I set this length to 24 characters? Using it in the below code.
I have a label control in datalist. When thw word is long, the text of label corrupts the design. Label hasn't a multiline property.I tried different ways . I tried to use textbox like a label but this time I can't give a link to textbox.I tried to use MeasureString() method for the label. But I couldn't do it.
I want label to display limited text say 20 char even the data it retrieve from database may be more than 20 char.. like in gmail,we see message body limited when we click it display whole message..how is that possible...?
I have installed VS 2010 Ultimate and it came with SQL 2008. what version it is and also how to create a connection in place to keep using the Oreilly examples to hopefully learn how to develop in C#. I have been learning but it is getting more difficult. I try to follow the steps but it just does not make sense. provide some easy steps to check version and connection method to sql using 2010,
I did see a post for sql management(http://www.microsoft.com/downloads/details.aspx FamilyID=08e52ac2-1d62-45f6-9a4a-4b76a8564a2b&displaylang=en). I am going to download to hopefully be able to view the database. We have sql server 2008 at work and I have used the studio management for sql to run queries and would like to do the same with the version that was installed with the installation of 2010 ultimate. I can get the connection to the database so I can start learning how to build a dictionary and list for some queries. My goal is to create a aspx file that will show entries in a database we have at work.
When i run the following code i get an error when gridview changes mode to Edit. stating that you can't change string to decimal!
To get around the occurance i want to disable code when in Edit mode or resolve another way?
GridView1_RowDataBound For Each row As GridViewRow In GridView1.Rows Dim cell As TableCell = row.Cells(7) Dim invoicetotal As Decimal = CDec(cell.Text)
on VWD 2005 this code works fine, but on 2008 it says I haven't created an instance of the object. I want to convert the object connString (a connection string) into a string.
'This acceses the virtual directory web.config file for connection strings 'We have to convert the object to a connection string Dim rootWebConfig As System.Configuration.Configuration rootWebConfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("/VirtualDirec") Dim connString As System.Configuration.ConnectionStringSettings connString = rootWebConfig.ConnectionStrings.ConnectionStrings("ConnectString1") Dim strConnString As String = connString.ToString().......
I'm concatenating a string in codebehind to use in a sql select statement.
in aspx
<asp:Label ID="LabelHidden" runat="server" Visible="False"></asp:Label> SelectCommand="SELECT * FROM [Data] WHERE [ActivityName] IN (@ActivityName) AND ([ID] = @ID)" <SelectParameters> <asp:ControlParameter ControlID="DropDownList_Employees" Name="ID" PropertyName="SelectedValue" Type="Int32" /> <asp:ControlParameter ControlID="LabelHidden" Name="ActivityName" Type="String" /> </SelectParameters> in codebehind foreach (ListItem li in ListBox_Activities.Items) { if (li.Selected) { queryBuilder += li + "', "; } queryBuilder = queryBuilder.Substring(0, queryBuilder.Length - 1); LabelHidden.Text = queryBuilder;
When i run the code it comes up blank. I did a query trace and it seems to be running as
exec sp_executesql N'SELECT * FROM [Data] WHERE [ActivityName] IN (@ActivityName) AND ([ID] = @ID)',N'@EmployeeID int,@ActivityName nvarchar(50)',@EmployeeID=4,@ActivityName=N'Production Technical Support'', Tools Development'','
with exta "'s
How can i format the queryBuilder string correctly in my code?
