Re: how to make any text file on the client computer ?

Short answer, No.

Internal browser security will not allow this.

You can put a FileUpload control (HtmlInputFile) on the page and allow the user to upload it.

You can do it using ActiveX. (Surely security and permission things would be involved!)

Not the exact code but these would help:

Similar approach discussed[^]

OR

Alternative could be to write file on server[^] and then download that on client system[^].

You need to set the initial value of the check box inside:

if (!IsPostback)
{
    // Set default values...
}

No, not really. First time into a page you want to set the defaults but not do it again when you Postback (unless you have a reason to do so). So, wrap in the code I gave inside, for instance, the OnLoad of a page and, when you select a new value in the checkbox and PostBack, the default is ignored and the new value will appear.

There is source code which insert person infomation to List<string>.
After below code, middleCategory_list have 200 subitems.
and have 20 people infomation.

I want to convert this to DataSet.

List<string> middleCategory_list.Add= List<string>();

middleCategory_list.Add(cate_big_La);
middleCategory_list.Add(cate_middlecode);
middleCategory_list.Add(cate_middlename);
middleCategory_list.Add(cate_order);
middleCategory_list.Add(cate_yes);

DataSet ds = new DataSet();
string tableName = "Table2";
ds.Tables.Add(tableName);

ds.Tables[tableName].Columns.Add("big");
ds.Tables[tableName].Columns.Add("middlecode");
ds.Tables[tableName].Columns.Add("middlename");
ds.Tables[tableName].Columns.Add("order");
ds.Tables[tableName].Columns.Add("yesno");

If you are guaranteed to always have all five columns of information in order then it would be something like this

for(int x = 0; x < middleCategory.Count; x += 5)
{
  DataRow row = ds.Table[0].NewRow;
  row[0] = middleCategory[x];
  row[1] = middleCategory[x+1];
  row[2] = middleCategory[x+2];
  row[3] = middleCategory[x+3];
  row[4] = middleCategory[x+4];

  ds.Table[0].Add(row);
}

Sending Status Messages

11-Jan-11 7:46

Hi All,

I have a ASP.Net Web Application which sends status messages to another JSP or some other web application throgh a WCF service hosted in my IIS 7.0. Normally it is sending the messages. But some times it may fail, so I want to re-send the failed status messages. So can anybody help me which approach is the best fit for this requirement?
I am confused about the approach, like whether should I use a database table to keep the failed records and activate it through the Windows service?
Or should I put the failed records in XML or Log files and read it from there resend it? Is there any other effient way than implementing Windows service?

Which is the best one please help me in finding the good option, for performance of the application and implementation?

Thanks & Regards,

It looks like you are trying to implement a guaranteed delivery mechanism for messages. If you want to build your own, you could implement it as a database message queue and have a separate process handle the delivery of the messages. You have all kinds of flexibility (and complexity) by implemeting it as a database table, but it is really up to you to decide how to implement it.

Proper Procedures to Prevent Cross Site Scripting.

badprog11-Jan-11 7:24

badprog

11-Jan-11 7:24

Issue: I need to prevent cross site scripting

Current Solution:
1. Create a token based on session id and time in the Global Session Start method.
2. Store token in hidden form variable on every page load.
3. On submission, compare form variable with session token.

Question: What is the proper way to implement my solution? This has to be wrong. I can not see in anyway how this would prevent CSS. Under no circumstances would the form variable differ from the session variable.
