I have a screen and in the code behide i have private class created inside the page
In this class i have a Hashtable
i will like to pass this hashtable from one screen to another by Querystring
I am trying to fix the size of the Hashtable with following code.
[code]....
I have fix the size of this Hashtable is 2 but I can add more than 2 elements in this, why this happen, I am doing somthing wrong?
I have tried to find out is this Hashtable have fix size of not with hashtable.IsFixedSize, it always returns false
I am building a Asp.net Application. I need to save a HashTable in a session.
At page load i am writing
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
Session["AttemptCount"]=new Hashtable(); //Because of this line.
}
}
Here problem is, when a user refresh the page, session["AttemptCount"] also get refreshed.
I want to know where should I declare
Session["AttemptCount"]=new Hashtable();
So that my seesion do not get refeshed.
EDIT In Global.asax, this session will get started, as soon as user opens the website. I want to creat this session only if user go to a particular page. i.e Login.aspx
I have a problem while checking a hashtable value. In the code below I am storing 60 values in the hashtable "hash". One of the values is (or can be) Null. I am checking each entry against its corresponding entry in hashtable "hash1", to see if they match each other. If they don't match I want to check if the value in "hash" is Null, but I can't catch it - it's falling through the 'else' part). How can I overcome this problem?

reasking some basics to clear out from this messed up things
1) difference between using normal array & using hashtable in terms of storage, access speed
2) is it possible to store values from serverside controls in javascript on client side in a normal array variable ( values can be of different types) even on postback??.
if yes how
3) currently i have hidden fields which stores values on client side and on postback saves in hashtable ie saving data on server & not on client.
1) As per my understanding, Session variables like HashTable and another variable in Session must be initialized. The best place as per my knowledge is Sesson_Start Event. But at some post its written that we must do that in Application_Start. I think it is not true, as that could lead to problems with different user sessions. Reference is this [URL] Let me know about the concept.
2) Storing variables like string, boolean and etc in Session is slower than storing objects in Session like HashTable, Arrays etc.. becuase they dont require boxing and unboxing. Is that true? Reference. [URL]
We are using static hashtable in webservice for sharing common data among different users. Is it safe? Is there any better way?

View 1 RepliesI am looking for opinions and best coding practices.I need to get info from a database with a query such as SELECT this, that FROM MyDB (returning 2 fields). Would it be wrong to use a hashtable for temporary storage?Is there a better way to accomplish the same thing? What about if I am returning more than 2 fields, would it be best to step up to a DataSet or something?

View 2 RepliesI have been presented with numerous word and excel docs. The goal is to put them online and bind to a database for the fields and also to store data for easy searching and reporting.
Has anyone done anything like this before?
I know the easy solution would be to create a database table for each particula form and also an ASP.net page for each form.
But then there are problems like printing and correct formating so it fits on the page, spaning multiple pages and so on.
And also is there any advice on how to write to PDF straight from the page?
I have a treeview named Treeview1 with checkboxes. I want the child checkboxes to be checked if parent is checked.
I am trying to use a simple code that I found on msdn :
[Code]....
For some reasons I got this error and I really dont understand why:
Type 'System.Windows.Forms.TreeViewEventArgs' is not defined.
warning BC40056: Namespace or type specified in the Imports 'System.Windows.Forms' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.
Really getting better with VS, but I've mostly been displaying data. I'm on a new project and now and I have a lot of data entry forms to create. I created a form to enter data into an access db and got it working. I thought it would be cool to add an edit button that fired a gridview to load on the same page, under my original forms, so that that they could load up the data and edit or delete mistakes. But when I try to update the gridview, it also tries to post the original forms (text boxes), which fail because there is no data in them, and I get an error.
What is the proper way to handle this in asp.net? I'm sure this is kind of a common issue. I've done some searching, but the search terms, like forms and gridview, are kind of generic and I'm not coming up with anything useful. I just need a more experienced person to point me in the right direction and I'll get it figured out.
I do have combo box on my page where the items are retrieved from database.
I have an link label which leads to new form to add value for corresponding column in database.
After add the value, when i click refresh on my current page, the values in combo box must be updated.
I have used this
private void button3_Click(object sender, EventArgs e)
{
this.Refresh();
}

Is there a way that I can create one form and reuse it across multiple projects?
I am using forms authentication, and for some reason it shuts off my images. I have tried putting them in the same directoy, and still nothing.
If I turn off forms authentication, they come back alive so I know my urls are correct.
My images show up find in design time, and if I have logged in and go back to the page, they show, but upon initial login,they aren't visible. What do I need to do?
View 1 RepliesIn windows forms, there is the "show data sources" under the "data" menu item, and I love it because I can drag and drop the fields I need onto the form and it makes the control automatically.In web forms however, this option isn't there. Why? I try to drag and drop fields from the "server explorer" but it generates grids, I don't want grids I just want to drag and drop the text boxes or checkboxes etc.

The login page is created with the masterpage and it has the header picture.
After Logout or run FormsAuthentication.SignOut();
The login page is not showing correctly with the header (from master page).
And the setting on the web.config as below:
<authentication mode="Forms">
<forms loginUrl="Login.aspx" name=".ASPXFORMSAUTH">
</forms>
</authentication>
<authorization>
<deny users="?" />
</authorization>
Is there any reason why the header from masterpage can not be viewed from the login page?
Form1 is for the administrator. It has 5 fields. Field1 has a value for which the other values give details about it. This 5 fields are stored in a table. Form2 is for a user and its a data entry form. This forms has 12 fields. Each label in the form2 corresponds to the value of Field1 in form1. If suppose the admin fields 10 times the form1. The 10 labels of form2 are filled with values of field each time. The above is what I want to achieve. Also the two text box corresponding to the remaining two labels should be disabled for user.
