Hi,
1. There is a SendTo folder under every user account. Just drop a link to your app there and it will show up in the Send To menu.
2. You can configure this under Explorer/Extras/Options/DataType. Visual Studio setup projects are able to automatically make the correct entries for your application.
3. Search this site for single instance[^]

Ok sorry, I wasn't very clear. I understand how to make file associations and to put things in the menus.
But I don't know how to write the hooks in my code to allow me to process the file I receive.

In general you just have to evauluate the parameters your Main function has. Have a look at the link I have provided. It not only shows how to do this but also how to pass those arguments to an already running instance.

Dear all,
I'm just starting out in .NET and creating a simple application to store the personel information on staff, e.g. name, address, age etc etc.
My question is which would be the best storage for this type of information. I'm considering XML or a database. The application will be run on a single machine so it just needs to be something simple. It would be nice to be able to load the information into Excel too...
Any pointers would be a real help so I start down the right path.
Many thanks
Tom

I found SQLite to be a very good and simple storage media for small databases.
There's a ready-to-use DLL provided by Mono, but it also works fine with normal .NET applications

File/Open?? Just opening the solution or porject file should launch the conversion wizard which will upgrade the project files to the current version supported by the IDE, IF the conversion is supported.

I'm looking to do something seemingly obvious:
Hashtable h = new Hashtable();
foreach ( key in h.Keys )
h[key] = //something;
but I take it the assignment h[key] kills the enumerator of the foreach. Is there an elegant way to implement the intent of the above code?
Thx.

You can't change the key of a node in a hash table, as the entire table is arranged according to the hash codes of the keys. You have to remove the node from the table and re-add the object in the node using the new key.

b { font-weight: normal; }

okay, but my intent is not to change the key. I'm trying to express
H[key] = //something;
That is, I'm setting my DictionaryEntry value to //something. Is there a way to use the foreach statement and assign values to existing DictionaryEntry's ?

Once a hashtable record is created, you don't want to change the key. Changing the value is fine though. Sometimes whan I need a quick and easy list of objects, I'll create a hashtable and just use hash.count as the key. Here is an example of how you could deal with changing values from a hashtable:
Hashtable hash = new Hashtable() ;
for (int i = 0; i <=10; i++)
{
hash.Add(i,"something") ;
}
//we now have 11 objects in the hashtable
int counter = 0 ;
//we do this, because hashtables don't guarantee that you'll
//get object out in the same order you put them in
for (int i = 0; i <= 10; i ++)
{
hash[i] = "new object" ;
//this will modify the VALUE, not the KEY
}
//if you don't care about the order you're getting objects out of the hashtable
//you can enumerate them like this:
IDictionaryEnumerator enumr = hash.GetEnumerator() ;
while (enumr.MoveNext())
{
object theKey = enumr.Key ;
object theValue = enumr.Value ;
//you could change the value here
enumr.Value = "new value" ;
}

The obvious: make a clone of the keys:
ArrayList keys = new ArrayList(h.Keys);
foreach (Key key in keys) {
h[key] = bla;
}
Wout

okay, so I have* to make a copy of the keys to use the foreach when assigning values to existing DE's. Thanks.

Just as some further info: Whenever you loop over some sort of collection with foreach you are not allowed to change it within the loop. That's no speciality of the HashTable class but affects about all collection classes.

Hello,
is there any way using WMI on how to copy files from local computer to the remote computer on the specified path/location[C#] ?
thank you in advance
|
|
|
|
|
Sure, Win32_Directory[^]. But why would you want to??? This is kind of the Rube Goldberg method of copying files. It has limited functionality, such as it won't over-write the destination file if it already exists.

we are using microsoft Office 9.0 Library & COM namespace is OWC
TextBox1.Text = xlsheet.ActiveSheet.Cells[i,1];
While writting this code it is not converting to object to string but in reverse case it is working properly uploading to spreadsheet.
//This is the Error
Error: Cannot convert Object to String
So pls convey this & let me know the solution for the above problem.
I m using asp.net with c# coding.
Thanking u,
Naren.
please help me

Try this:
TextBox1.Text = (string) xlsheet.ActiveSheet.Cells[i,1];
Best regards, Alexey.
|
|
|
|
|
TextBox1.Text = xlsheet.ActiveSheet.Cells[i,1].ToString();
Every object in .NET has a .ToString() method

All solutions are incorrect.
Correct code:
<br />
Excel.Range cell = (Excel.Range)m_workSheet.Cells[x + 2, y + 1];<br />
string st = cell.Text.ToString();<br />
Best regards, Alexey.
