How do I modify a value in Dictionary? I want to reassign a value to a value in my dictionary while looping on my dictionary like this:
for (int i = 0; i < dtParams.Count; i++)
{
dtParams.Values.ElementAt(i).Replace("'", "''");
}
where dtParams is my Dictionary
I want to do some thing like this:
string a = "car";
a = a.Replace("r","t");
I have a class that maintains a static dictionary of cached lookup results from my domain controller - users' given names and e-mails.My code looks something like:
private static Dictionary<string, string> emailCache = new Dictionary<string, string>();
protected string GetUserEmail(string accountName)
{
if (emailCache.ContainsKey(accountName))
{
return(emailCache[accountName]);
}
lock(/* something */)
{
if (emailCache.ContainsKey(accountName))
[code]...
public class CacheHelper { /// <summary> /// Removes object with the specified key. /// </summary> /// <param name="key">The key.</param> [code]....
I have this methods for caching..I need to change this methods to use in aDictionary<string,object>
How do I need to change this code Because I am new to asp.net I am still learning..
I want to create a Dictionary... where i can get Dictionary database or World lists (english to english , english to hindi)
View 1 RepliesI have an issue with a Loop that doesn't actually loop. I've posted a simplified version of my code below. Basically, using the NPOI excel library, I have an excel file with data on the first and second sheet, so I need to do a loop to get through both sheets. Below is what I have done so far, however this only works through the first sheet and then exits. It fails to increment the variable w. As you can see, there are other loops implemented in this code which function fine so I don't get it.It's been a very long day and perhaps I'm missing something very simple. I could have it placed wrong or something. If anyone else can spot what I might be doing wrong I'd be very grateful :)

I have the following line of C# code that successfully returns the results of a stored procudure via a DAL:
spParamGetGamesTableAdapter spGG10 = new spParamGetGamesTableAdapter();I can bind spGG10 to a DataGrid and see the stored procedure query results, so I know everything is good so far.I want to loop through the spGG10 (DataSet table?) and output each row on a row-by-row basis using a Literal Control. I think I know how do the output part,How do I access the data in spGG10 and loop through its records? (Also, I am not exactly sure what kind of object spGG10 really is. Is it a table?)
consider the follwing table, this table actually shows which id was given a new id
i.e 11 was assigned 13
again 13 was assigned 15
15 was reassigned 17....and so on actually 11,13,15,17,19 represent the same user (hope u understood)
customerId rejoiningId
11 13
13 15
15 17
20 21
17 19
48 50
21 25
i need to loop through all the rows and find the relation that which all ids are interlinked
say the user enters the rejoining id -13,hence the result should come out to be as 11,13,15,17,19
if user enters 21result should be 20,21,25
it takes a bit of looping statements in query that i couldnt figure out
I'm currently trying to move through all the values added to a listbox by the user, however, I want to retrieve the actual value of each item in the listbox and not the text.
I've gotten so far with the code below, but that only gets the text and not the value.

How would I go about getting the value for each item in the collection?
I'm still new to ASP.NET, and I'm trying to rewrite a simple booking/reservation system I did in ASP, but I'm struggling to find an equivalent technique in ASP.NET.
Basically, it a nested recordset. The first recordset returns weeks from a calendar. for each record returned, a basic table row is created, showing the dates & prices then the start of the week is used to query a bookings table to see if there are any bookings for that week. If there are bookings, the <tr> & <td> tags are modified to change to colour & wording to reflect the bookings.
an extract of the code is as follows:

i am trying to loop through a gridview using jquery, the code i am using is
$('#<%=gridview1.clientid%> tbody tr').not(':first,:last')
.each(function(){
gridrows ++;
});
i would like to eliminate the first and last rows which are obviously the header and footer , i tried this code but seems that it is not working, it is returning the count of gridview rows.
I have several controls on a web form Dropdown list, text boxes etc. Which are going to be used as part of a stored procedure to enter data in several SQL Tables. One of the boxes is called the number of items now depending on the number inputted here is how many items to be inserted therefore I need to loop so my stored procedure to run again
Not sure if this is relevant or just me confusing myself and making this more complex than it really is but I have several data readers running before I run my stored procedure to help get the data I need for it.
Here is the SQL for it and the answer goes in label1 so then further down when the insert stored procedure runs it checks the value on label1 to run an if statement so I will need this procedure to run as well in the loop.

I have the following values: customerNumber, ProductNumber, PartNumber.There exists a directory structure on a server like follows (the bold italic text is the actual value)://myServerName/Parts/Images/CustomerNumber/ProductNumber/PartNumberSo the part of the file directory that is constant is://myServerName/Parts/Images/but the file structure CustomerNumber/ProductNumber/PartNumber will vary, displaying the actual number valuesEX: //myServerName/Parts/Images/11111/22334/007so I need some code that will loop through the file Directory structure under "Images" and will get the string values of each subdirectory. This will be used to find the image to be used for the specific CustomerNumber, ProductNumber and PartNumber.Does anyone have any good sample code where you have done this before?
View 3 RepliesWhich of these will perform better if we assume that the IF block in #1 will be executed more and less in #2
foreach()
{
if
{
block here
}
}
or
foreach()
{
if !( )
continue
}
I've structured #2 to take the if conditional less often.
How to loop through the table get only paticular records based on the particular value and store it in a datatable.
for example, i've a table with two columns, Store name and Store number. For a single store name it can have mulitple store number like
[store name ] [store number]
a1 10
b1 12
a1 15
a1 21
b1 11
b1 22
a1 25
etc....
How to loop through the table and get all the records/ rows of a paticular store name and store it in a datatable.
i have a table which contains a bunch of dynamically created radio button lists, im trying to write code which will loop through each one of the radio button list and get the text value of the selected item. i have the following code
foreach ( Control ctrl in Table1.Controls)
{
if (ctrl is RadioButtonList)
{
//get the text value of the selected radio button
}
}
but i am stuck on how i can get the value of the selected item for that given control.
to loop through each field in a record to test for a value and then set a flag at the end of each record if an instance of this value occurs in any fields?I have a table where some fields values are have a *c* at the beginning of the text eg "*c* value" . What I would like to do is run a select query off the table and at the end of each record have a field called "Change Flag" and a value of "Changed" or "No Change" depending if a *c* has been encountered.
There are a number of tables to run this against all with differening numbers of fields/
i have searched quite a bit on this one and can't seem to find exactly what I am looking for.
I think my first problem is this: How would I bring back a DataTable FOR copying? I know I would need:
Dim dt as Datatable
But then how do I get the Original Datatable in there? I think that once I have that part, I can just make a connection to my new DB inside a copy subroutine (using the .Copy method) and be done with it. That part I have the code pretty much done for, I think.
im trying to retrive all the values in the datatable
but i keep getting only the first value
since i just finished learning C# i have no idea how to solve that
here the code i use let me know what am i missing

I've a asp:Calendar control and to each date, dynamically when the calendar renders i'm adding a checkbox next to it.
The user can check and uncheck the checkbox , based on that i need to send the checked dates to my database.
Now, my problem is that i have no idea what to use to collect the dates list to send it to database.

{
e.Cell.Text = "";
CheckBox c = new CheckBox();
e.Cell.Controls.Add(c);
c.Text = e.Day.DayNumberText;
