You should put whatever value you are matching on as the key in the dictionary, so that you don't have to loop through them.
A dictionary uses hash codes to quickly find items by key, so that is very much faster than looping through the data.

I've never heard that. Case-sensetive culture-invariant comparison is faster than case-insensetive culture-dependent comparison, if that is what you mean.
If you use the dictionaries correctly, it will only do one or a few string comparisons to locate each item, so the speed of string comparions is hardly an issue.
Despite everything, the person most likely to be fooling you next is yourself.

Indeed, that's what I have done.

Of course! Its not going to be looping as such is it.

Gotcha, thanks.

hallo i need to programmatically format a hard disk.
Apart from ShFormatDisk, it seems that there's a hope by using FMIFS.DLL or UNTFS.DLL.
Has anyone a piece of code to show me?
Out there there are just old broken links to sysinternals site regarding FMIFS.DLL.
Thanks in advance

Why do you want to format a disk? Are you writing a virus?
|

If he was it would be a sh*tty virus, no gain in formatting a disk. Maybe he means a removable storage device?
|
|

thanks for the interesting replies, it's curious that everywhere i find a thread for "hard disk formatting" there's somebody asking if it is for virusing. Sounds like if a programmer wants to write a scanner software, it is for duplicate identity cards... Evil Is Everywhere :P
BTW has anyone serious idea of how to write a function to erase an internal (no removable, no flash memory) hard disk?
|
|
|
|

Nah can't help you there, I can't see any possible gain at all for formatting an internal hard drive. Tasks like that should be done by a user without any programmatical assistance through any application not specifically designed for that, it can lead to accidental formats, which should be limited and not encouraged.

Thanks Uwe. Yes i tried, they mainly suggest ShFormatDisk.
I'm trying to give my end users/customers a clean restore environment without dos boxes and nags, using imagex, but i need to format the disk before applying an image.

solved: i launch a command line Process with FORMAT using /Y, an undocumented flag for the unattended mode

Hi
Is there any possibility that I could cast an object through its handle.
For example, I have to do an estimation of objects and finally I get the handle of that object through GetWindow API call, now I know its type but how to retrieve that object and cast it for that specific type?
I am implementing it using a dll file.

What kind of handle - an HWND?
If so, there is no built in association between an HWND and an object.

Hi
Thanks for the reply.
Yes, it is an HWND. To make it more clearer, the handle is of a IE's statusbar32 object, for which I know only the handle, now I want to manipulate its objects and add/remove other Microsoft Common Controls so I was thinking of a way to cast that object to comctl's statusbarclass and then manipulate it instead of throwing Messages and creating pane window etc. using API calls as I am not very good in that.
Hope I was clearer to specify my scenario and you would have the solution to it.

You'll have to use APIs unless there's some other programming model
built into IE, which I wouldn't know

AFAIK, you cannot do that. The best you can do is send messages to that handle. The object doesn't exist in the managed environment, so there's no way to cast it to be a managed object.

Hi
Thanks for the reply. Actually I already considered that but that seems very complicated as I am willing to create another control and append it to the control whose handle is known to me. i.e. add label control into statusbar control of IE.
I hope you have a solution to this.

There is no way to cast that handle to an object, .NET managed, COM, or otherwise. AFAIK, IE doesn't expose any method to do what you want.

Hello,
I'm trying to figure out how to display lines of text with more than one color. Seems like anytime I want to change text color for a word in a string, I can't, because all the text changes to that color.
If you need an example, consider something like AOL Instant Messenger. The person sending the message has their name in one color, and the receiver has a differently colored name.
Can the standard Textbox control pull this off? Short of that, is there some kind of custom control that can do this operation?
Thanks,
Michael Fritzius

Hi all:
I met a problem about communication between a Buisness layer and UI layer in a three-tier application.
In my project the UI layer invoke a method in Business layer named DoSomething(), DoSomething() method need to finish three tasks: (1)read data from database. (2)handle these data. (3)write them to excel file. However sometimes it need interact with the customer according to the data in step (2), so I should notify the UI layer to create related interation window. Here comes the question: how should I pass the message to UI layer?
One way to solve this problem is to use delegate, but if I use delegate I should know the method need to be invoked in UI layer first, that reqire Buisness layer import the UI layer dll, but you know that disobeys the import rule of a three-tier application.
What I need is the Business layer notify the UI layer: here we need the interaction with customer, just notify.
Can some one tell me the way to solve this question? Thanks.

Create an event in your Business Layer like AdditionalInformationRequested, which the BusinessLayer will invoke in step 2 if needed, and the UI can handle the event. You can have a custom EventArgs object that the UI will fill that will provide the information needed for the Business Layer to proceed with step 2.

Probably really simple, but I'm stuck and its been driving me nuts for the whole week.
The Problem.
Creating a dynamic number of Control.Image at runtime that holds various pictures load from a folder.
Each Image shares the same context menu
the problem is
when i click on one of the context Menus MenuItems say "enlarge" I have set it to all go the the same event handler
i.e = new system.eventhandler(enlarge_click)
how do i pass the argument of which image control I open the context menu from?
i.e
new system.eventhandler(enlarge_click uielement Image[x])
Thanks a lot
I looked into delegates but i must be be missing something, because i cant see how this would solve my problem.
thanks
