suppose x=3,y=4
Response.Write(x.ToString + " " + y.ToString)
This gave correct as i thought: 3 4 But this gave unexpected result, so what's the rule behind string concatenation and conversion?
Response.Write(x.ToString + " " + y).
This gave :7. Why could'nt 'y' here got converted to string ? why arithimatic sum happend here?
I want to create a program that allows me to enter the name of a table, a field along with a value. The program should concatenate the values to form a valid SQL select statement. I can also modify the program to include multiple field names and values. Example: -Select “FieldName” from “TableName” where “FieldName”= “Value” I have created 3 textboxes called and 3 labels named Select, From and Where This is my code here, i would need an assistance on the right way to achieve this, maybe mine is wrong.
Partial Class _Default
Inherits System.Web.UI.Page
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim SelectItem As String
Dim From As String
Dim Where As String
SelectItem = txtSelectItem.Text
From = txtFrom.Text
Where = txtWhere.Text
lblDisplay = "Select" & " " & SelectItem & " " & "From" & " " & From & " " & Where
End Sub
End Class
how this string concatenation taking place? i am really confuse what is happening why that slash i there and how the double quotes are used
SessionStateItemCollection items = new SessionStateItemCollection();
items["LastName"] = "Wilson";
items["FirstName"] = "Dan";
foreach (string s in items.Keys)
Response.Write("items["" + s + ""] = " + items[s].ToString() + "<br />");
Response.Write("items["" + s + ""] = " + items[s].ToString() + "<br />");
I have a string variable that is a concatenation of text and a variable;
var selectQueryString = "SELECT * FROM WholesaleItems WHERE ProductClass like '" + @pc + "%'" ;
This returns with a space between the variable and the percent sign breaking the LIKE selector. I cannot find any way to trim the variable result.

"<div id='" + myMsgs[j].id_chat_message + "' style='padding: 10px;'>"
so, each div have the same id in page and in database. now a want to find some div, with jquery, but it doesnt work
for (var j = 0; j < myMsgs.length; j++) {
findDiv = $('#<%= ' + myMsgs[j].id_chat_message + '.ClientID%>');
}
i know that my problem is the concatenation of the strings, but i dont know how to solve it.
I'm using LinqToSql like this with a CheckBoxList in ASP.NET:
var teachers = from x in dc.teachers select x;
cbl.DataSource = teachers;
cbl.DataTextField = "name";
cbl.DataValueField = "teacherID";
cbl.DataBind();
I want to display both "firstname" and "name" in the DataTextField however. I found this solution but I'm using LINQ: [URL]

I've built this app that displays employee photos stored in several sharepoint folders. It also displays the employee name extracted from the file name and a previous and next button to move through the photos.
The markup is surrounded by an update panel to prevent the entire page from reloading when you click to view the next photo.
The app is working fine in firefox, but the images do not display in IE8. Can anyone tell what is causing this?
public List<string> photoFileList = new List<string>();
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)

I'm concatenating a string in codebehind to use in a sql select statement.
in aspx

PropertyName="SelectedValue" Type="Int32" />
<asp:ControlParameter ControlID="LabelHidden" Name="ActivityName"
Type="String" />
</SelectParameters>

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'','

How can i format the queryBuilder string correctly in my code?

I have project in development where string operations like "Hi " + variable + ", welcome to Project" are used at many places (given example is very minor one).
One of the requirement is to convert it to string.format style.
It is very long and tedious job, where I would not like to break earlier working code due to any human error might happen while converting it.
I would like to if any Macro or VS command which I can create to handle it. Just like we mark block of code and do Extract function in Re-factor options.
I want to split a string that taking both string and integer values like (Cmp_12). I want to use them in Separately.

Just the paragraph where the result was found. Maybe even put that particular word in bold. how best I can implement this?
View 1 Repliesi have created a encrypted string to match with a target string to pass it along with client URL for authentication. it doesn't match. here is an algorithm used to create a encrypted string.
text = "astringtobeencrypted";
string strglobalkey = "mytestglobalkey";
string hexivkey = "testing12345";
ebCryptLib.eb_c_Cipher ci = new ebCryptLib.eb_c_Cipher();
string strhex1 = ConvertStringToHex(strglobalkey);
string strhex2 = ConvertStringToHex(hexivkey);
byte[] bytes = (byte[])ci.EncryptStringRaw(EB_CRYPT_CIPHER_ALGORITHM.EB_CRYPT_CIPHER_ALGORITHM_DES3_ECB,
strhex1, strhex2, text);
return Convert.ToBase64String(bytes);
the above alogithm returns a string which doesn't match with our targetted string provided by the client.
what should i do to match with the targetted string? The client had generated the encrypted string using PHP.
