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 have a datagrid and I set up the paging based on how many rows there are like this
With dgBookings
.AllowPaging = True
.PagerStyle.Mode = PagerMode.NumericPages
.PagerStyle.PageButtonCount = 5
.PageSize = 5
End With
Is there a way to set the horizontal-align in the code too I tried adding this
.PagerStyle.HorizontalAlign = Right
and I get this errorArgument not specified for parameter 'Length' of 'Public Function Right(str As String, Length As Integer) As String'.
When I use code from this thread: [URL] (converted to VB.net), the result for lblStatus is always "nothing"?
It's not clear for me why you use "label", because the fieldtype I am searching for in the gridview, is boundfield.
I have a 15 digit string to encrypt.
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 store my setting in a string, the parse the string out to load into the forms controls..
The string looks like this..
100,34#101,54#102,Smith#103,12/12/2009# etc
This string can be 1000 characters long..
Question : No matter the string length can I test the string to see if its exactly the same as another like
Dim Str1 as string
Dim Str2 as string
string.equals(Str1,Str2) = true
Will this still work ok, no matter then size/length of the string...
I've create an asp.net MVC 2 project, it works fine!!
I've been asked to integrate the project in an existing web project in classic asp.net
(I've add the folder containing the source, and not make a new project, because they have to bee in same project)
I've configured my web.config file

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.
View 11 RepliesIm getting this error while developing login page "The length of the query string for this request exceeds the configured maxQueryStringLength value".
View 1 Repliesi need to cut the text from a box to a shorter version. what i'm using right now is :
CAST(DescriereNoutate AS nchar(200)) AS Descriere from the SqlDataSource, but im having problems because this cuts the words.
how can i do this without leaving the words cut in half.
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...?

View 2 RepliesPassing 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-

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.
String is immutable and StringBuilder is mutable. So if I change the value of a string a new memory created with the new value, whereas in StringBuilder it updates its memory location rather than creating a new memory location. So for large concatenation stringBuilders are preffered. But when I create a new String object, a fixed memory is created. And any changes will update its memory location, rather than creating a new memory location.
For e.g.
String s = new String();
s = String.Empty;
for ( int i=0;i<100; i++)
{
//s = s + "test" + i.ToString();
s =string.Concat(s, "test" + i.ToString()); ///This is effecient compared to previous step
}
Now instead of String class I will use a StringBuilder class.
StringBuilder s = new StringBuilder(String.Empty);
for ( int i=0;i<100; i++)
{
//s = s + "test" + i.ToString();
s.append( "test" + i.ToString());
}

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 am exporting a HTML table to excel by sending the data as a HTML Table string and setting the content headers:

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.
if (Convert.ToInt16(row["rnum"]) == 1)
{
dr = GLinks.NewRow();
dr["rnum"] = row["rnum"];
dr["L_URL"] = row["L_URL"];
dr["CG_GalleryName"] = row["CG_GalleryName"];
dr["L_Picture"] = row["L_Picture"];
GLinks.Rows.Add(dr);
I've got 3 connection strings in my app:

now in the code i do:

I get: The ConnectionString property has not been initialized. What am I doing wrong? AFAIK this should get the value I want...
I don't want to do in connections section as I WANT TO BE SURE that I don't mess up the production server since I'm in the same network...
I have some problem to understand how this example works with the updatepanel. I have put a ListBox4 and a label inside an updatepanel and put the property for the ListBox to AutoPostBack = true; So what I now am trying to do is when I click on the four items in the ListBox, I want the label to update the new String that is clicked in the ListBox. However what first happens when I click the 2:nd item is that I get the error:
Index was out of range. Must be non-negative and less than the size of the collection. I wonder what the correct way is to do this. I am not sure to know what is right here ? I think many example I do will be solved if I learn this one.

I have a table in my database, in which a certain field holds the locations of text or doc files (the files are of a transcript for a chat session).

I have a web project with a data model defined in an edmx file. The connection string starts like this:
metadata=res://*/;
This has worked fine for a while. But somebody else working on the project created a dll that also uses the entity framework and added it to the bin folder. Now when I try to create my connection there is an error loading the metadata.
Aside from totally changing the way one or both of us is doing things, I wonder if the problem can be fixed if my connection string can be changed to only look for the metadata defined in my edmx file. The problem is, for the life of me I can't find the right syntax to do this. The metadata is embedded in the output assembly, so there are no physical metadata files to point to. How exactly should I specify the metadata location in the connection string?
How can I retrieve the Entity Framework 4 connection string from a custom config file, not web.config?
Edit: Is it reasonable to delete the default constructor generated code and recreate it in a partial class to use the pulled in connection string?
I would really like to avoid changing all references to the EF context with an overloaded method including the connection string.
