Searching? Are you kidding me, it's part of the Reflection API, I mean if your read the freakin documentation it's right in front of your face.

~~GetEvents deserved a string (name) additionaly to the BindingFlags.~~ Bull sh*t! Sorry

Hey Martin.

I have tried the DeclareingType approach, it didnt help me, sadly.
I know i can use the bindingflags, but that will not resolve in one modifier, more likely 2 or more modifiers. maybe its just me... i didnt have this problem with any other Reflection types like FieldInfo or MethodInfo... Confused | :confused:

No, but you read the doc correct and do not mix up the methods!

Man, led mike, one would hardly like to post any question again when you send an reply like this... Frown | :(

I dont think your link solves my problem.

let me try to explain:

			IsPublic		IsAssembly	IsFamily		IsFamilyOrAssembly		IsFamilyAndAssembly
Public			True		False		False		False			False
Internal			False		True		False		False			False
Protected			False		False		True		False			False
Protected Internal		False		False		False		True			False

FieldInfo has these properties (IsPublic, IsAssembly, IsFamily, IsFamilyOrAssembly and IsFamilyAndAssembly)
but the EventInfo does not have them...

Yes, I have a very sarcastic attitude because we get some real monkeys here on CodeProject. Perhaps in your case I have been to harsh.

Paw Jershauge wrote:

You could be correct because I have not gone to the trouble to implement it and prove that it works. However it seems from the documentation that if you call GetEvent() with a name and the BindingFlags you are interested in you can determine the information your original post asked about:

Paw Jershauge wrote:
Does anyone know how to get the modifier of an Event?

So you can't "get" it but you can determine it, yes? There could also be a more direct way to "get" it, I don't know but at least you are not stumped at this point. If I wanted to know more I would continue to research the documentation.

I have be researching the document, and tried alot of the samples provided by Microsoft, but i have yet to find the correct way to handle this problem.

EventInfo[] AllEvents = type.GetEvents();<br />
foreach(EventInfo ei in AllEvents)<br />
{<br />
	string modifier = ...[The code that solves the modifiers]...<br />
	string eventfullname = modifier + " " + ei.Name;<br />
}<br />

Just example... D'Oh! | :doh:

Please help me convert the C# code to VB.Net

11-Mar-08 6:17

As this was really troubling me. i found the solution from an guy called boothwine on the MSDN forum.

I seems that one would have to do following:

EventInfo[] AllEvents = type.GetEvents();<br />
foreach(EventInfo ei in AllEvents)<br />
{<br />
	string modifier = "";<br />
	if(ei.GetAddMethod(true).IsPrivate)<br />
		modifier = "Private"<br />
	else<br />
		....<br />
	string eventfullname = modifier + " " + ei.Name;<br />
}

The GetAddMethod returns an MethodInfo this helps...

Thanks for taking the time to try an help me...

Hi,

I beleive this sample code is in C#:

string cleanString = String.Empty;<br />
Regex reg = new Regex("[A-Z]|[a-z]");<br />
MatchCollection coll = reg.Matches(<MyStringGoesHere>);<br />
for(int i = 0; i < coll.Count; i++)<br />
{<br />
cleanString = cleanString + coll[i].Value;<br />
}

See, i want to remove all characters that do not fall in the A-Z or a-z OR 0-9 category AND replace it with a space...
example test123t3er = test t er

Am i wrong in saying that the Regex reg = Regex("[A-Z]|[a-z]") CAN IT BE: Regex reg = Regex("[A-Z]|[a-z]|[0-9]") ???

AND the cleanString = cleanString + coll[i].Value;
CAN I DO A TEST: IF(coll[i].Value == String.Empty) THEN cleanString = cleanString + " "; ELSE cleanString = cleanString + coll[i].Value ???? - in this way i add space if the character is not in the above category????

So please help me convert the very top section of code and i will build from there...

Thank you in advance...

I believe this is the VB.Net code

<br />
Dim cleanString As String = [String].Empty <br />
Dim reg As New Regex("[A-Z]|[a-z]") <br />
Dim coll As MatchCollection = reg.Matches(<MyStringGoesHere> ) <br />
For i As Integer = 0 To coll.Count - 1 <br />
    cleanString = cleanString + coll(i).Value <br />
Next<br />

Windows Application Security using SQL 2005

ChrisKo11-Mar-08 8:09

You could easily do this in a RegEx by itself and avoid looping through the matches. \W captures all non-word characters (anything not a-z A-Z or 0-9), so you can then just use the Replace method of the Regex class.

Dim resultString As String
resultString = System.Text.RegularExpressions.Regex.Replace("ABC$%123*>890!#XYZ", "\W", " ")

I haven't done VB since VB6, but I assume that should work as it's a simple statement.

Hi,

I need to write an Windows Application where the user authenticate against a SQL 2005 Server. What I need is to have a custom authentication and authorization system that's available when building ASP.NET apps.
How would I go about finding out how to type in a Username and Password and then authenticate against a SQL server.

Thank you

GetFiles() Problem

Hi all,

im working on a Solution to grab all Files in a Directory, but the Compiler woudn't accept my Code. He says all the Time (string have no definition for "GetFiles"

Here is my Code

private void Form3_Load(object sender, EventArgs e)
{
string dir = @Application.StartupPath + "\\XML\\";
DirectoryInfo tdir = new DirectoryInfo(dir);
FileInfo[] dateien = dir.GetFiles(); //<-- Here the Compiler underline GetFiles as a Mistake, why
}
Why he do that?
Thanks for helping
Daniel

Hi, if file name (string[]) list is enough for you, you could use Directory.GetFiles(dir) static method too. (That's what I usually use, dunno why your code shows error.)

Oh, your code should say "tdir.GetFiles()" I think Smile | :)

it sits right in front of you, there is dir and there is tdir, they ar not the same.

if you want to program, you should be able to spot a mistake in the line the
compiler tells you is wrong; rest assured, the compiler will be right almost
all the time, and way more often than you are.

Thank you alot, Ferenc Veres, it was that, what you said, the code should say tdir instead of dir.

if you want to program, you should be able to spot a mistake in the line the
compiler tells you is wrong; rest assured, the compiler will be right almost
all the time, and way more often than you are.

I know that i should be able to analyse and interpret compiler mistakes, and i even dont know, why i put dir before getfiles()
Maybe it wasnt my day yesterday, ... anyway thank you for your help and maybe next time i can help you Smile | :)
