C# - Allocating Data In Array With Same Length String?
Jan 14, 2011
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 know I can use arrayName.length to find out how many items in total in the array there are, but how can I gracefully find out how many items are in a specific dimension? I know I could probably do it in a for each loop, but it would look a little messy, does anyone know of a simple way that I may have overlooked?
it is really annoying that I am keep getting these error. what is that. we started to get this afte we updatet the net framawork for security vulnaribility. here is the error we keep getting. but not everytime;
System.FormatException: Invalid length for a Base-64 char array.

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 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.
i have an string data array which contains data like this
5~kiran 2~ram 1~arun 6~rohan
now a method returns an value like string [] data public string [] names()
{ return data.Toarray() } public class Person { public string Name { get; set; } public int Age { get; set; } ) List<Person> persons = new List<Person>(); string [] names =names();
now i need to copy all the data from an string array to an list<person> and finally bind to grid view
I am selecting data from database and in while loop, i want it store all data in one variable. How to do that? The variable selectAnswer is string array type .
I used this code but this give error. Modify this code.
string selectAnswer[] = new string[]; while (rdr.Read()) { selectAnswer[] = rdr[0].ToString(); }
I have a gridview where I can browse an user's information. Through the gridview I'm also able to edit some of this information. A recent change in my client's needs demands that one of these fields is now a DropDownList. This field represents a user's "schedule" (not literally a schedule but works like one), and the different schedule options to be assigned to a user are shown in the drop down list.
Problem: In the drop down list I want to show list items like "9-12 15-17", "10-14 15-18" so that it is easy for the administrator to tell which schedule he's assigning to an user. However, that shouldn't be their actual value. I need "9-12 15-17" to actually be '1' since this is the schedule ID that I'm trying to pass on to the DB.
Here's what I have so far: [Code]....
And with this last method I change the selected item's value to the Index. Meaning that if I select "9-12 15-17" which has an Index of 1 in the dropDownList, the actual value is now 1. Again, this is the behavior I expect. My experience with ASP is quite little as I'm new on this, but as far as I know, this only actually updates the string array. How would I go about modifying this to reflect my updates on the database? All input is taken into account.
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'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.
[Code]....
I get the following error:
Index and length must refer to a location within the string. Parameter name: length
