You can get and set pixels of a bitmap using Bitmap.GetPixel(x, y) and Bitmap.SetPixel(x, y, Color). Unfortunately, the GetPixel & SetPixel methods are extremely slow, you might want to use the Fast Bitmap[^] class which gives fast access to pixels by using pointers and unsafe code.

After that i can access the file through my .NET code. But after logging of from my machine and then again logging in, that code does not work.
Can anyone please tell me how can i pass user credentials through my .NET code to access remote machine file.

Thanks to all,

How to control html page containing frame object by AxWebBrowser?
I wrote the code as following.

-----
HTMLDocument doc = (HTMLDocument)this.WebBrowser.Document;
object index = 1;
IHTMLWindow2 window = (IHTMLWindow2)doc.frames.item(ref index);
doc = (HTMLDocument)window.document;
-----

The error message was like this (I'm sorry for Japanese):

-----
'System.InvalidCastException' のハンドルされていない例外が mscorlib.dll で発生しました。

追加情報: インターフェイスがサポートされていません
-----

I tried translate above message.

-----
non-handled exception 'System.InvalidCastException' was occurred in mscorlib.dll.

additional information: interface is not supported
-----

the same problem occurred when I tried this code

-----
HTMLDocument doc = (HTMLDocument);
MessageBox.Show(doc.frames.length.ToString());
-----

So, what is the problem?
Please help me ...

Perhaps doc.frames.item(ref index) isn't returning an IHTMLWindow2 interface? I'd check that in the debugger, see the actual type that is being returned before assuming it is an IHTMLWindow2.

No, that misses the mark.
Because this error occurs even if the code doesn't use the cast.

What happens if you go

object o = doc.frames.item(ref index);

?

Is this a high transactional database. What is the rate of such events. I had encountered similar scenario and I did the following

(1) If any event occur in the database, write the data to a Database Table inside a trigger( specifically for this).
(2) A windows service in Client keeps polling this table after say every 30 sec.
(3) If records are found do the refresh.

Hope this helps.

Thanks,

Well if it is C# class then you can reference your dll in another C# project... COM registration is unnecessary in this case.
Just right click on References in Project EXplorer (assuming you use Visual Studio) and add your dll... you can then simply use all public classes in that dll.

Subscribe to the button's click event (Double click on the button in Forms Designer, if you're using VS) and then inside the event handler, check if the textbox's Text property is equal to String.Empty

Hi!

Im new to c# but I'l try my best to be of help.

i) the answer is posted just about 5 topic post below yours

ii) I think its either you create 2 search buttons one for the ID no and the other for the name or create a dropdownlist that triggers the search function when you select one of the items inside it. Name or ID.

of course its only logic I still have to figure out how to do it by code. hehe

hope that helps...even for bit Big Grin | :-D
