I was wondering if there is a way to write to the extended file properties in Wdindows. I know how to read them from a file.
For instance if I wanted to get the Artist's Name in a mp3 file I would use the GetDetailsOf method from the Shell32 object. I would do GetDetailsOf(folderItem,9) to get the value of the artist name.
However there is no "SetDetailsOf(.....)". I want to write a program to set those extended file properties to whatever I please. Is there any way to do this??? There must be a way. Any help would be greatly appreciated.
Thanks,
Matt

I have an app im developing that accesses a web site (Thanx to Adn Brummer for helping with that part), i new want to access a different area of that web site (that has its own URL), essentially i have a page that lists numerous documents, i want to send a POST to be able to get the properties of a specific document. i have sent the POST (got the commands to send from Fiddler) and i keep getting a "Session Timed Out" message (amongst the HTML code), but this does not happen when i access the site online (via IE).
the following is the command i am sending to access wat i want.
offset=0&resultRowBlockSize=12&matrixColSpan=4&show=thumbnail&targetDocId=31242&displayedDocIds=31242&selectFlags=false&displayedDocIds=31240&selectFlags=false&displayedDocIds=31238&selectFlags=false&displayedDocIds=31236&selectFlags=false&displayedDocIds=31234&selectFlags=false&displayedDocIds=31232&selectFlags=false&displayedDocIds=31230&selectFlags=false&displayedDocIds=31228&selectFlags=false&displayedDocIds=31226&selectFlags=false&displayedDocIds=31224&selectFlags=false&displayedDocIds=31222&selectFlags=false&displayedDocIds=31220&selectFlags=false&orderBy_property=ReceivedDate&orderBy_descendingRequested=true&dummy=
can anyone help me with this (if u need more info, or code snippets, let me know)

This is probably happening because you are not returning a session cookie that you received from a previous GET. Once you receive a session cookie you must return it with every HTTP GET or POST to that web site. Take a look at the Cookies property in the HTTPRequest class that I'm sure you are using.

Thanx, ill have a look at that, i did come across the fact that it was applyin a different session ID when i called my POST.
im storing all the cookies i get (as far as i know) into a global Cookie collection, that seems to have a COOKIE with the name of risessionid, but im not sure what to do with it.(sorry about these, im new to web development)
i also noticed that the Id works fine, as long as the URL of my page doesnt change, i have a page that lists documents, and if u scroll through the list, the page changes but the URL doesnt, but the second i change the URL it doesnt work.

Its ok now, i managed to get it to work, i jsut simply created a Cookie object and assigned the Session Id cookie to this object, not it all works perfectly, thanx for the help, and pointing me on the right path
thanx

Hi
I have doen a program, her is some part of the coding
DateTime current = System.DateTime.Now;
DateTime end = DateTime.Parse(textBox1.Text);
TimeSpan ts = current.Subtract(end);
I am calculating as follows. But now i want to know the default format of dateTime.
in texBox1.text, i will give a time.... then that sould be calculated fromteh current time of teh system.

Hi I have done a program using system.threading.timer....
now in that i will input the time in a textbox, say 03:00 pm..
now i have to format in that way, i mean hour:minute..
here is the part of my coding
//system timing
DateTime current = System.DateTime.Now;
//texbox,wher i wil give time
DateTime end = DateTime.Parse(textBox1.Text);
.//then i willcalculate the timespan.
TimeSpan ts = current.Subtract(end);
but only in the second part of my coding. i willgive as 03:00 pm in the textbox,which should be accepted.
so please help me how to format the datetime.
I read from MSDN and articles to use
{t}
, but i dont know exactly how to implement.. so please help me by explaining how to code that part..
js---ie, hour:minute wise...
so that if i give 05:30pm should be able to accept and calculate the timespan.
so please can anyone help me to solve this issue.

Hi
I want to get data from Access instead of notepad.
Here are the codes to get data from notepad by entering IC number (equivalent to ID number). The records are stored in 'Folder'.
<br />
public void btnGo_Click_1(object sender, System.EventArgs e)
{<br />
enable(); <br />
<br />
strFileName2 = tboxEnterICNo.Text;<br />
path = @"Folder\"+strFileName2+".txt";<br />
<br />
if(File.Exists("Folder\\"+strFileName2+".txt"))
{<br />
displaygraph.names = path;
displaygraph.ShowDialog();
}
else<br />
{<br />
MessageBox.Show("File does not exist! Please create a new profile.", "Invalid File Type", MessageBoxButtons.OK, MessageBoxIcon.Error );<br />
}
}
How should i go about to keep the records in Access and also specify retrieving of the queried data from an Access table instead?
I need some help about what to do and how the codes look like.
Thank you very much!

You've been loading text files, and you want to move to an Access DB ? If you google[^] C# Access Database, you get heaps of links to articles on this sort of thing.

hi there,
if u need to keep the records in Access DB, u need to have basic knowledge of mechanism of accessing to Access DB, such as: ODBC, OleDB, ADO or ADO.NET.
u can get more detail and also simple codes from MSDN
To query from Access DB, u also need to know SQL query. This can be got from SQL Book Online

Hi hi,
If it's using oledbadapter and dataset, i know how to use them and query for data from Access.
However, what i need now is how do i automatically store the data downloaded into Access instead of storing in Notepad?
How do i get every set of downloaded data to append to my Access db table??
Thank you!!
|
|
|
|
|
after u downloaded data need to be stored into Access DB, u can use sql query that is something like "insert into ur table(field1, field2,..) values (...)" to insert the data into Access DB

See the FunA() and FunB() result, why any diffent?
<br />
private void FunA()<br />
{<br />
double value;<br />
System.Text.StringBuilder sb = new System.Text.StringBuilder();<br />
for( value = 2.1; value >= -1.1; value -= 0.1 )<br />
sb.AppendFormat("Ceiling({0:f})={1} Floor({0:f})={2} Round({0:f})={3} (int)({0:f}+0.5)={4} Truncate({0:f})={5}\n", value, Math.Ceiling(value), Math.Floor(value), Math.Round(value), (int)(value+0.5), Decimal.Truncate(Convert.ToDecimal(value)));<br />
return sb.ToString();<br />
}<br />
private string FunB()<br />
{<br />
double value;<br />
System.Text.StringBuilder sb = new System.Text.StringBuilder();<br />
for( value = 5.1; value >= -1.1; value -= 0.1 )<br />
sb.AppendFormat("Ceiling({0:f})={1} Floor({0:f})={2} Round({0:f})={3} (int)({0:f}+0.5)={4} Truncate({0:f})={5}\n", value, Math.Ceiling(value), Math.Floor(value), Math.Round(value), (int)(value+0.5), Decimal.Truncate(Convert.ToDecimal(value)));<br />

Why same procedure, only diffrent value of starter, but has many diffrent? Float is so wonder, how can i make it exact.

Use double or Decimal, they are more precise.

It already is double!
=== Game is power! ===

OK, then try Decimal. Floating point isn't precise, that's just how it is. 1.5 + .5 is probably 1.999999, and then casting always rounds down.
Christian Graus - Microsoft MVP - C++

You can't make it exact using a floating point data type. A floating poing value is often not exactly the value you specify, as some values can not be represented exactly.
For an example, the value 2.00 might actually be 2.000000000000001, and using Math.Ceiling() on that value will result in the value 3.0.
---
b { font-weight: normal; }
|
|
|
|
|
I see. So that's say I can not get a very exact float value.
But the other question is why the procedure is same, only diffrent between the begining value and loop times, it will make this difrrent.
As you said, every time Math.Ceiling(2.00) must equal 3, but why in FunA() it is equal 2.
They all are called by Math.Ceiling(value) and the value=2.00, the very small gap can not explain this result.
=== Game is power! ===

.1 cannot be represented in binary, as a result when the 2nd loop should reach the same value the first one starts at, it actually different at the last few decimal places and will either be slightly above, or slightly below the expected value.
|
|
|
|
|
You start at different values. When you get to 2.00, you have made a different amount of adds, so the accumulative error is different. That's why the result differs.
