Well not me actually, but you are right; I just need similar knowledge.

No it doesn't. Visual Studio does. Behind the scenes, there's a fairly continuous parsing/compilation process going on out of process, and it is this that raises this. It's this process that provides the smart tag functionality to allow you to add the implementation of an interface or identify that a method is missing, etc.

Hi
I try debug my work in VS 2008 but PC and HTC WM6 (.NetF.work 3.5 installed) understand numbers diferently. First thing, number format in my region separated with coma 0,1.
What i cant get to work:
Test1 number in the textbox cosfi stored like us format 0.9 (not coma)
<br />
A.Text = System.Convert.ToString(Math.Round(System.Convert.ToDouble(cosfi.Text), 2) * 2);<br />
A.Text in PC test 1.8
In the phone i get error FormatExeption double.parse....
Test2 number in the textbox cosfi stored 0,9
A.Text in PC test 18
In the phone 1,8
<br />
A.Text = System.Convert.ToString(Math.Round(System.Convert.ToDouble(cosfi.Text.Replace(",", ".")), 2) * 2);<br />
With this metod all the same, PC give right answer 1.8 and phone give me error.
Can anyone help me out?

The chances are that your PC and phone are set to different locale. Your PC is set to work with '.' as a decimal separator, and your phone with ','
You can either set the PC and the phone to the same locale, or (if you must, because it will restrict where your App works) specifcy the locale when you do the conversion. See TryParse[^] which allows you to specify which locale you want the conversion done in.

First: PC and phone are both in same local.
Second: Both work in same separator.
Third: Compact.framework not suport TryParse
Fourth: I dont have this problem if i write app for pc in Visual Basic (comma separator return always right answer).

You said the emulator (not the PC) and the phone work differently. The way you described, these two ARE set to different locales. You provided all the proof needed to establish that.
Mees Metsast wrote: Third: Compact.framework not suport TryParse
You don't have to use TryPrase. double.Parse also takes a IFormatProvider parameter that DOES work on .NET CF.

There are no two ways about this. The problem you are facing is because of an incorrect locale setup on your test device, probably the emulator.

Sorry, this is my second app for phone and only now i get how this thing work (hard headed).
I tried to find a emulator settings under the VS2008 menu but this needs to be configured when it is running like normal phone (regional settings in the emulator itself).
Thank you for pointing right direction.

hi ...
WE are developed a windows based desktop application in c# . Now need to give license protection for that application. we are decided to give dongle license key . but have no idea about that . How can we achieve that ..please give the solution of these...
Thankyou!!!!

Dongles are hardware keys - best thing would be to buy them, mostly you'll get a free booklet explaining how to interface with it. I'd suggest the USB-key dongles since you can stack those more easily than the parallel ones.

Hi,
I am wondering if it is ok to use the following snippet ? I am suspecting that, as the object license will be disposed after this block, the caller of GetLicense method will get null object all the time, right ?
public virtual EncryptedLicense GetLicense(LicenseContext context, Assembly assembly, Type type)
{
..........
using (EncryptedLicense license = LoadLicense(context, null, licenseKey))
{
return license;
}
}
As my class EncryptedLicense is Disposable, my refactor tool (CodeRush and ReSharper) is asking me to place the statement EncryptedLicense license = LoadLicense(context, null, licenseKey) within using. But, I am getting worried if it is a correct practice or not. Would you please suggest!.

IMO, since you want to use your license code elsewhere, why do you want to put it in a using statement?
You are not going to call dispose() on it anyway.

Hi Abhinav,
Thanks for ur reply. So, that means, I should not use 'using' here, right ? I got the answer.
|
|
|
|
|
AFAIK, there is no point in you using using here.
Me, I'm dishonest. And a dishonest man you can always trust to be dishonest.
Honestly. It's the honest ones you want to watch out for...

When using a "using" construct, when execution leaves the "using" block for ANY reason, the object specified in the "using" block is Disposed and destroyed. You cannot return an object created in the "using" statement to any caller since it won't exist any more.

Thank you Dave, thats the answer I was looking for. I was confused about it, now I am clear.
|
|
|
|

I agree, however that also tells me the compiler should reject the code as it cannot possibly make sense.
|
|
|
|

Another one for MS to consider.
|
|
|
|

It can't figure it out because if license is declared before the using but not necessarily instantiated, it can still be used to instantiate another object after the using block.

No, not null, but it should be unusable -- however that depends on what the Dispose method actually does.
I write Dispose methods for a lot of things, not all of them leave the instance unusable.

Hi,
Thanks for your reply. I just started learning to use Dispose method and I am highly confused about one thing. WHY Microsoft created this new pattern when the Class Designer can put all memory cleaning logic in the Destructor of the class ? Because it is very easy to miss calling Dispose method for a new programmer and I have seen hundreds to source code where programmers are not calling dispose method or using 'using contruct' for Stream operations. Even in the popular open source library 'HtmlAgilityPack', I dont see the programmers are Calling Dispose method in Stream operations.
==> Also, I am wondering, even the Windows Form generated Code in Main method in Prgram.cs file in any Windows Application, the Entry Point Form is invoked without using 'using construct'. So, can you please give me any light about it please !
Regards.

To clean things up before the destructor gets called?
