This error could be because of a type mismatch - but since the type used for list is not given in your examples it's impossible to tell.

I think I found the solution: COnvertAll method of the COllectionBase Collections.
//Collection to list
SCG.List oColl = new SCG.List();
oColl.Add(new B("Michelle"));
oColl.Add(new B("Chris"));
oColl.Add(new B("kathy"));
SCG.List<iclass> ListA = oColl.ConvertAll<iclass>(new Converter<b,iclass>(ConverttoIClass));
public static iClass ConverttoIClass(iClass obj)
{
return (obj as iClass);
}

FOund the solution using PowerCollections Algorithms class:
ctlDemographics.Vendors = new List<ivendor>(Algorithms.Convert<contractvendor, ivendor="">(Contract.GetVendors<contractvendor>(Contract.eDataDetail.Basic, this.ContractID, ref oCE, 1, 300, out TotRowCount), Vendor.ConverttoiVendor));
Had to create a Convert Delegate, very simply:
public static iVendor ConverttoiVendor(iVendor oV)
{
return (oV as iVendor);
}
THen just pass that to the constructor of a new generic List<>.

Hi All,
I am sure this has been answered somewhere, but I have scoured the web for a couple hours and seem to find the question being asked but never answered. My problem is simply this:
I have an LDAP query that simply pulls the groups out of Active Directory and adds them to listbox. The application works perfectly on my development box; however, when I take the application live as a website on a development server instead of groups being returned and added it only adds 1 line to the listbox, "System.byte[].
Here is what my code looks like, pretty basic directory searcher:
private void PullGroups(string DistinguishedName)
{
DirectorySearcher ds = new DirectorySearcher("mycompany's domain");
ds.PageSize = 0;
ds.SearchScope = SearchScope.Subtree;
ds.ReferralChasing = ReferralChasingOption.None;
ds.SizeLimit = 100000;
ds.Filter = "(&(objectClass=Group)(objectCategory=Group)(ManagedBy=" + DistginuishedName + "))";
SearchResultCollection src = ds.FindAll();
try
{
foreach (SearchResult searchResult in src)
{
string groupName = searchResult.Properties["sAMAccountName"][0].ToString();
lstGroups.Items.Add(groupName);
}
}
catch
{
}
}
Any help on this would be greatly appreciated. Thanks, Matt

It looks like the return type from the property is actually an array of bytes making up a Unicode string. Calling ToString on it will do exactly what you described as the problem. Try doing this to get the bytes converted to a string:
using System.Text
.
.
.
string acctName = Encoding.Unicode.GetString(searchResult.Properties["sAMAccountName"][0]);

Hi Dave, thanks for the response.
I tried the code you suggested, and it gives the errors
The best overloaded method match for 'System.Text.Encoding.GetString(byte[])' has some invalid arguments
and
cannot convert from 'object' to 'byte[]'
I am guessing that the property collection is of the object type. What perplexes me the most is that the group names are returned fine running from Visual Studio, but when I bring this to a webserver it gives me the byte array.
I'm going to continue to work with the encoding though, I think that is where the problem lies as you suggested.

You can cast the object to a byte array, then pass that to GetString.

I was able to solve this one by removing impersonation as true in the web.config and using an impersonation context only in the method which determines what user is accessing the page, then removing the context after this information is passed into the methods working with the Active Directory.
Looks like it was an authentication issue. Hope this information helps anyone who has come across this problem.

Hi,
I need to search for hard coded strings from the VC++ 6 / VC++.Net 2003 source code.
Is there any tool for this?
Is there any criteria to define the search for this?

Have you looked under the Edit menu? Perhaps "Find..." or "Quick Find..." would do what you want...
|
|
|
|
|
I would say, anything what is between two '"' is 'hardcoded' string... so search for '"'.
Or maybe I don't understand what you need

I have some arrays declared as,
Dim upperCases() As String = {"ALPHA", "BETA", "GAMMA"}
Dim lowerCases() As String = {"alpha", "beta","gamma" }
...many more arrays
I need to read appropriate array based on the parameter passed to the function
Function getText(ByVal pos As Integer, ByVal arrayName As String) As String
'I want to do something like
Return arrayName(pos)
End Function
Could anybody help me please?

If you're looking at doing something like this, you most certainly don't need it. If your code is smart enough to pass in the correct array name and element number, it's smart enough to just do Dim str As String = upperCases(x) without going to a function to do it.
You cannot do what you want, how you to do it. It would take using Reflection methods to do something like this. It would also be a very expensive operation to return a value, so if performance is an issue, this isn't they way to do it.
You'd have to do something like this:
Public Function getText(ByVal pos As Integer, ByVal arrayName As String) As String
Select Case arrayName
Case "upperCases"
Return upperCases(pos)
Case "lowerCases"
Return lowerCases(pos)
Case Else
Throw New ArgumentException("Invalid array name passed!")
End Select
End Function

Dave,
Thank you for reply.
When you say to do something like,
Dim str As String = upperCases(x)
That is what I am tring to do, which does not work.
To make sure that prog pass the correct array name I have created an Enum that has all the array names, which I access as
Enum AllArrays
EmployeeGrade
EmployeeDepartment
EmployeePrivileges
EmployeeSlab
EmployeeAgeGroup
End Enum
Dim arrNames As String() = System.Enum.GetNames(GetType(AllArrays))
Dim readArray As String = colorNames(AllArrays.EmployeeDepartment)
I get the correct array name to access in readArray.
Now, when I try to read it using readArray(0), It returns the first character of array name i.e. "E". readArray(1) returns "m" and so on. I understand it is happening because readArray is a type string, but is there a way to do what I want to do, other than using select case or If..Else.
Thanks again.

I already told you, no.

The only other method is to use Reflection, but it's incredibly slow.
You really need to rethink this design. You're treating variable names as an integral part of the Data and Business Logic, which you should NEVER do, nor do you ever need to do it in a proper design.
You're combining functions that really should be seperated. You're needlessly trying to get a single function to return a value from a number of arrays when this is never necessary.
If you want functionality like this, put your data into DataTables.

Does anyone know how to convert a generic collection to a generic KeyedCollection? I need the benefits of the KeyedCollection to be able to get items by index as well as by key. Now the problem is that my middle tier is returning generic collections. I would like to create a KeyedCOllection class that has a constructor that you pass it a Collection like List and Collections have. Anyone have any ideas on how to go about doing this?

Hi,
principally you can simply inherit from KeyedCollection and add a constructor like this one:
public MyKeyedCollection(Collection<TItem> items) {
foreach (TItem item in items)
base.Add(item);
}
The problem which might arise is implementing the abstract GetKeyForItem function. This is hard (impossible?) without knowing what kind of content the list has. You could use a delegate for this which you could also put into the constructor, but its hard to make an advice on this without knowing the exact requirements.

That wouldn't be a problem as one of my type params will be of a common Interface which in turn has UNiqueID as property and all objects will have the same property name. I guess Generics can only take you so far. Delegate is a great idea though to get around this. I was thinking of creating a constructor this way but was concerned about performance and just though there would be implcit conversion so as to avoid the iteration.
THanks

Hi,
I am writing the following logic for SQLMembership password reset:
SqlMembershipProvider objSqlMembershipProvider = new SqlMembershipProvider();
strPassword = objSqlMembershipProvider.ResetPassword("testusername", "testanswer");
Inspite of setting the proper values of required attributes (enablePasswordReset="true"), it throws following error:
This provider is not configured to allow password resets. To enable password reset, set enablePasswordReset to "true" in the machine.config file.
What might be the reason?

In your web.config file or in your machine.config file where you define your provider there is an attribute in the xml that is the enablePasswordReset. Currently that attribute doesn't exist or is set to false. So you need to find your Membership provider in whatever config file it is in and add the attribute with true.
Hope that helps.

Hi,
I have already set that attriute as True. But still this problem exists.

My only guess then is that you set it in the wrong provider. It needs to be set in the membership provider that your site is using. Perhaps you have it set on one level and then you are overwriting that value on the next level. So perhaps you have set it to true at the machine.config level, but it is set to false in the web.config level?

Hi,
I am digging into WPF and i have found that the control used to display webpages (Frame) cant be used as a Visual Brush.
How can i find a form of displaying webpages in a way that i then can use it as a visual brush in a 3D surface?
Thx,
Nuno
