I know this thread is ancient, but I just found the answer. The installation DVD copies a demo C# / VB.net solution to your C:\T32 directory as C:\T32\demo\api\dotnet\dotnet-files.zip\dotnet

Seems to be working for me so far!

Working with value pairs(a key and a value)

Hi all,

I want to save pair of values, a key and a related value of it. I use HashTable to store them as follows.

<br />
private System.Collections.Hashtable hshTable =<br />
new System.Collections.Hashtable();<br />
<br />
hshTable.Add("One", 1);<br />
hshTable.Add("Two", 2);<br />
hshTable.Add("Three", 3);<br />
hshTable.Add("One", 6);<br />

Check that last line, I cannot do that. Actually what I want to do is, on existing entry value should be updated.

How can I solve this problem.

Thanks Smile | :)

I appreciate your help all the time...

hshTable["One"] = 6
If there is no item with key "One" new item will be added. If there is, old value will be overwritten.

Hi,

you can also call Hashtable.Remove(key) before calling Hashtable.Add(key,val); there is no need to test for existence first.

The same principle applies to the generic Dictionary<T> class.

BTW:And it is similar to removing-then-adding a delegate to an event.

Thanks for replays.

Actually I got data pair like One 2 and so on. I want to store each of them. If I found a duplicate one value(number) should be updated. Then later I want to take all of them to make a string.

Say my data like this.

One 3
Two 5
One 7

Then the string should be,

One 7 Two 5

I appreciate your help all the time...

Hi,

you can add/replace key-value pairs as shown before.

for a Dictionary<(TKey, TValue> you can enumerate all keys
with foreach(TKey key in Dictionary.Keys) {...}

and similar stuff goes for old Hashtables.

WARNING: dictionaries, hashtables don't preserve chronology, so there is no guarantee that "One 2" will come first in the enumeration. If you insist on having that, you will need a different approach,
most likely a combination of a List and a Dictionary (a List preserves order unless you instruct it to drop the order, e.g. by sorting).

Use a generic Dictionary(TKey,TValue). It has a ContainsKey method which will return TRUE if the key supplied exists. If it exist, just update the value instead of adding new one.

hello

How can u think of storing the different value with the same "Key"

As u mentioned "One"====> the key ... how it can be repeated under the same instance

Make a custom function for it which check whether this entry is already there or not by

hshTable.ContainsKey("one")
if it there then remove it as
hshTable.Remove("one");
and again add as
hshTable.Add("One", 6);

Cheers!!

Hi,

create a 5-line method to do what a single statement can do? I suggest you (re)read Giorgi's and my earlier replies.

I think it is easy to solve your problem with many ways:

e.g:

use the combination of your key and value as new key;

Hello , there.

I saw the C# sample codes its a Windows Live ID for Client DLL.

So I thought I could change delphi2007 win32 code.

I tried to use a auto making import feature.

Therefore component -> .net assembly import -> create unit

But I could not use functions well becasue there are just inferfaces and

connecting functions.

Can't Client DLL assembly .net dll of Window Live ID released use other language for win32?

Can i use this .net dll or not?

Thanks. Have nice days.

Thank you

Hi,
I’ve define a panel on my from and define the panel dock as none, and increase the panel height each time I add new item at the button of the panel, once the panel size exceed form size, the form create vertical scroll bar and its great.
The problem is that I can use the mouse in order to scroll down the panel but the keyboard is not working such as page up, page down, up key and down key
Any idea,
I look at the form and panel property and I didn’t find anything that could help

Thanks,
Ronen
