WTF is right.
What sort of question is this from somebody with MCSD.NET.
I dont have any Microsoft certs but if this is the value of them i wont bother.

What is the general consensus on this idea?
According to the series of videos I have been following on MS about designing class libraries, you really should not throw exceptions in property setters. But, if you don't then how are you to signal the user that you have set a value that is not correct?
For example I have a property that takes a Guid value. Inside the property I want to make sure that the value supplied is a correct Guid (ie: formatting, length, etc...) and I am using regex for that, but if I determine an incorrect value what should be the way I signal the user?

If you don't want to throw an exception, then you have to set a flag or make your whole object go into an indeterminate state. I'd be in favour of throwing an exception, but leaving the object in a 'clean' state, so it can still be used if that's what the client wants.

That's what I am doing now. Just wondering if there is a more preferred method.
I am always looking for better ways of doing things.
Thanks.

I guess the idea behind the suggestion is that users of your class won't be expecting a simple property assignment to throw an exception.
If it's your own codebase, I guess it's fine then. Or, you can always change it to a method.

I am having a bit of a time trying to figure out which assemblies my application would like in order to run.
Actually, I am getting a CLR Debugging Services exception when I try to start the app. I know this happens when I am missing a referenced assembly. So I check the References -all of the DLL's listed there are contained in the GAC or in the application directory. The app of course runs perfectly on my development machine.
So I guess I have two questions.
1. Is there a way to capture in a log file which assembly the app died trying to load? The default "there was an error" message is just about useless.
2. I have looked in the .NET Config - Applications and checked the "Assembly Dependencies" listed under my app when I add it. There are several assemblies that are listed as being required multiple times (i.e. several versions???). I have no idea why this is happening. On my Dev. machine, these are listed only once with one single version. On the other "clean" machine (no VS, etc.) the dependencies show up multiple times - same executable.
How do I actually figure out what is happening here? Any insight on this would be greatly apprecitated.
thanks

This might help.
So might this.
And, if those don't help, try Reflector.

Hi,
My name is Liran, Im working on a project that the server is written in java technology (APACHE TOMCAT) and we considering now to turn the client to windows application instead of web. Our main option is to choose .net c# as our client technology and the connection to the server will be by web services on the server side (the webservices is written in java).
I already made a prototype to check it and it worked really good.
Im trying to get some information about the risks that i need to take into consideration if i choose this option. so if someone already dealt with it ill really appriciate your help.
Best regards,
Liran

Dear all,
The function System.Windows.Forms.Control.GetChildAtPoint(Point pt)
find control reference to the Control's Client Rectangle.
However, I am looking for a Control that is out of screen.
i.e. out of the Client Rectangle, but within the Display Rectangle.
Is there any method for me to get that Control by a Coordinate point?
Many Thanks.

Are you looking to get a control that sits on a different Form?

It is on the same form.
The control hierarchy is like this:
Form
|-Groupbox A
|---TextBox A
|
|-Groupbox B
|---TextBox B
However, the size of the Form can only show the Groupbox A. I have to scroll down in order to show another groupbox.
Now I have the coordinate of Groupbox B and TextBox B, can I get the control TextBox B by its coordinate point when the screen is still showing GroupBox A???
Many Thanks!!

You'll just have to try it. There is a chance that it might not work because it's not visible, and therefore, not being drawn.

Why don't you download the Visual studio express editions [^]including the MSDN library express ?

Dont install it, just download it and install only the Library and you will have the documentation without using the vs.

i got a problem about WMI.
i want use wmi to config my network adapter, such as ip address, subnet mask, etc. and i found some methods of Win32_NetworkAdapterConfiguration class can do this, but they are all enable method, for example, EnableDNS ,it can enable DNS setting and specify dns search order.
THE PROBLEM is how can i DISABLE DNS search, namely , obtain DNS server automatically.
|
|
|
|
|
Call EnableDHCP. It sets the adapter to get all of its settings, including DNS stuff, from the DHCP server.

Is it possible to make a project use the 1.1 framework instead of 2.0?
Since most people have 1.1 installed by now, but nearly noone has 2.0 I would still like to develop for 1.1 but use VS2005.
|
|
|
|
|
Nope. 2005 uses the 2.0 framework only.
Just install both. They run fine together.

SharpDevelop 2.0[^] supports developing for both 1.1 and 2.0.
I think you could use a similar way (a custom MSBuild target file) to do the same for Visual Studio 2005.
Unfortunately just changing CscToolPath is not enough because VS will try to always reference the 2.0 Framework libraries.

I have project dependent on "SSPI.h".
However, during the conversion to the .NET 2.0 Framework,
when I try to complie "SSPI.h", I get the following error.
error C2440: '=' : cannot convert from '__const_Char_ptr' to 'wchar_t __pin *'
Following is the piece of code which gives error:
wchar_t __pin* pwszServerPrincipalName = NULL;
if ((credential->SecurityPackage == Credential::Package::Kerberos) || (credential->SecurityPackage == Credential::Package::Negotiate))
pwszServerPrincipalName = PtrToStringChars(serverPrincipalName);
I tried out by changing Project properties->C/C++->Language->Treat wchar_t as BuiltInType to "No (/Zc:wchar_t-)" and comiling again. But still the problem is there.
Any suggestions how to proceed.
Same code works properly with vs.net 2003
