Hi,
I really think that this lib is a good base for an app framework. The only problem I personally see is that you have to provide exception policiy and logging category names by string literals.
One maybe tend to use string constants, better than nothing. But .net offers reflection, so there should be a way to get all those defined policiy and logging category names at the end of the day out of an assembly, right? This makes it type safe for coding and easy to config for admins as well. Possible scenario could be to generate app.config file with each policiy and loggin category name included for a default config.
Did somebody write some attribute based code to use the Microsoft Enterprise Library features?
myMsg.BehindDaKeys = "Chris Richner";

Hi Mark,
The goal should be to retrieve all those defined names from a compiled assembly. Nobody can remember all defined names after the assembly is released, right? Imagine the defined config file get lost. In this case one have to watch in the code (MyClass.Getxx()) to make sure all defined names are configured well again. Not really handy if one is out there by a customer trying to setup the whole thing again.
That's the reason way I like this attribute based solution, one could write a small tool that uses reflection to fetch all names out of the assemblies. To generate a config file containing all defined names is just a nice to have thing, of course.
Thanks for your answer.
myMsg.BehindDaKeys = "Chris Richner";

Sorry but I wouldn't show up at the client site without all the tools and code necessary to recreat/redeploy the application
only two letters away from being an asset

of course  it should just serve as an example... any way.. would be a handy thing to be able to get all cat names out of the compiled assembly... forget about the customer scenario 
myMsg.BehindDaKeys = "Chris Richner";

No ( as someone said ) BUT the express editions of VS2005 are free, you can use those to get a leg in on .NET 2.0, at least.

SetupDiGetDeviceInterfaceDetail(hDevInfo, &devInterfaceData, devInterfaceDetailData, dSize, &requiredSize,&devInfoData);
devInterfaceDetailData->devicePath returns a unicode USB flash drive directory. How can I read files one by one stored in that directory.
The returned devicePath looked like this:
\\?\usbstor#disk&ven_lexar&prod_jumpdrive_sport&rev_3000#106a11161813070406&#{53f56307-b6bf-11d0-94f2-00a0c91efb8b}
thanks ahead

Hi,
I'm facing a weird issue on one of my applications on a customers machine. I cannot reproduce it on my machine but I'm trying to understand what might have happened according to the log.
Basically the following code is executed:
public override bool Modify(LabelProperties properties, object[] values)
{
try
{
if(values[0] == null)
return false;
int sourceIndex = Convert.ToInt32(((Key)values[0]).Value);
}
catch (Exception exc)
{
_log.Error("Modify - " + exc.Message, exc);
try
{
_log.Info("Key Value: " + ((Key)values[0]).Value);
}
catch {}
return false;
}
return false;
}
The following information gets logged:
10:58:07 | Error | HiddenCategoryFeaturesLabelModifier::Modify - Die Eingabezeichenfolge hat das falsche Format.
at System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info)
at DE.IVU.FilialInfo.Map.ThematicMaps.Modifiers.HiddenCategoryFeaturesLabelModifier.Modify(LabelProperties properties, Object[] values)
Two things seem weird to me:
1. Although I'm using Convert.ToInt32 only System.Number.ParseInt32 is logged with the call stack.
2. The log call in the exception handler isn't done, which is weird because the first exception occurs in the number conversion routine. Thus I assume the cast and the property getter Value are working fine. But why aren't they within the handler?
Basically my question is if this behavior can be explained with the optimizations happening in the optimized release build. Does optimization really replace higher level calls with lower level calls?
(Just as a note: _log is a log4net.ILog instance and I assume it is working correctly. At least I didn't have any issues with it till now).

Hi,
1. Although I'm using Convert.ToInt32 only System.Number.ParseInt32 is logged with the call stack.
As far as I know, Convert.ToInt32 does a check for null parameters and then passes the parameter to lower level methods. However, I still would have expected to see Convert.ToInt32 in the stack trace.
2. The log call in the exception handler isn't done, which is weird because the first exception occurs in the number conversion routine. Thus I assume the cast and the property getter Value are working fine. But why aren't they within the handler?
The _log.Error call is done, therefore I assume the _log.Info call is done, too. What filters do you have applied to the log? I typically set the log4net filter level to WARN or ERROR in release versions.
Regards,
Tim

I'm logging all levels. To be sure I just made a quick check and saw many other log entries of type Info (even coming from the same logger instance) but this one is missing.

The Convert.ToInt32(string) method just checks for a null value, then calls Int32.Parse. It's quite possible that this code is inlined by the compiler.
The inlined code would in that case resemble:
string temp = ((Key)values[0]).Value;
int sourceIndex = (temp == null) ? 0 : Int32.Parse(temp, NumberStyles.Integer, NumberFormatInfo.CurrentInfo);

Hi,
Can any one suggest me how Visual Studio 2005 runs with out IIS??? I have uninstalled the IIS in my machine and try to run ASP.NET, it's working....

Visual Studio 2005 includes a stand-alone web server - a derivative of the Cassini sample[^] - which can host ASP.NET applications when debugging. This is very helpful if you're not a local administrator.

![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif) How can i post only two special characters in textbox by using VB.net, Can u help plsssssss
|
|

If your subject is the same as your text, the subject is way too long, or the text way too short. Or both, as in this case.
Don't write everything using bold.
You have to be more specific for anyone to be able to help you. What do you mean by "posting" characters in a textbox? What is it that is special about the characters? Why the limitation of two characters?
As you state that you want to use VB.NET, why didn't you post the question in the VB.NET message board instead?

I am not sure what the special characters are. Maybe you could use a MaskedTextBox or a MaskedTextProvider.
For a simple fix you could handle the key press event. In my app I just wanted post code data so I limited the MaxLength property of the post code text box and handled the key press event not allowing any chars others then numeric chars to be entered.
<br />
Private Sub PostCodeTextBox_KeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles PostCodeTextBox.KeyPress<br />
If System.Char.IsControl(e.KeyChar) Then<br />
Exit Sub<br />
End If<br />
<br />
Dim validChars As String = "0123456789"<br />
<br />
Dim ch As Char<br />
ch = e.KeyChar<br />
<br />
If validChars.LastIndexOf(ch) = -1 Then<br />
e.Handled = True<br />
End If<br />
