Hello All,
I'm having some trouble with this Web Service that I'm writing for work. The web service needs to sign incoming/outgoing requests with a valid X509 Certificate. I've written and tested the service here on my machine and it works fine with test certificates that I made via the makecert tool. My Company purchased a certificate from a well-known CA, but for some reason I can't get the Service to operate coorrectly with the purchased certificate. As far as I can tell it is installed correctly on our server (IIS 6.0). When I try to access the certificate programatically per the code below, I get an error that "the keyset does not exist". The private key file is there, I can pull it up with the WSE 2.0 Certificate tool and view the file, the permission are also correct, I'm logged in as Administrator with full control over all the directories/subdirectories.
CODE :
Private Function getSigningToken() as X509SecurityToken
Dim res as String = String.Empty
Dim securityToken As X509SecurityToken = Nothing
Dim store As X509CertificateStore = _
X509CertificateStore.LocalMachineStore( _
X509CertificateStore.TrustStore)
Dim open As Boolean = store.OpenRead()
Try
Dim certs As X509CertificateCollection = _
store.FindCertificateBySubjectName(cName)
Dim cert As Microsoft.Web.Services2.Security.X509.X509Certificate = _
CType(certs(0), Microsoft.Web.Services2.Security.X509.X509Certificate)
If cert Is Nothing Then
res = ("You chose not to select an X.509 " + _
"certificate for signing your messages.")
securityToken = Nothing
>ERROR HERE --> ElseIf (Not cert.SupportsDigitalSignature Or(cert.Key Is Nothing)) Then
res = ("The certificate must support digital " + _
"signatures and have a private key available.")
securityToken = Nothing
Else
securityToken = New X509SecurityToken(cert)
End If
Catch ex As Exception
res = ex.Message
Finally
If Not (store Is Nothing) Then
store.Close()
End If
End Try
Return securityToken
End Function
Do I need some special kind of certificate?
Shouldn't any type of X509 certificate work for signing soap request?
Any help at all is much appreciated. I've been searching the internet for a solution for about a week now. I've seen many who have this problem, but none have posted solutions (with the exception of security permissions, which I don't believe is my problem). Thanks in Advance for all your help.

Hello all,
I am using asp.net 2.0 GridView control. This grid is enabled Paging, i.e like this...
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)<br />
{<br />
GridView1.PageIndex = e.NewPageIndex;<br />
BindMessageGrid();<br />
}<br />
. This is working fine.
This Grid is having 3 columns(Name,Suject,Date) I am sorting the columns like this...
<br />
protected void GridView1_Sorting(object sender, GridViewSortEventArgs e)<br />
{<br />
int index = GridView1.PageIndex;<br />
DataTable dt = GetDataTable();<br />
DataView dv = new DataView(dt);<br />
<br />
dv.Sort = e.SortExpression + " " + GetSortDirection();<br />
GridView1.DataSource = dv;<br />
GridView1.DataBind();<br />
GridView1.PageIndex = index;<br />
}<br />
This Grid is showing 3 pages. When I click on first page first column(Name), first it is showing in Descending(i.e Z,Y...A) with same 3 pages.
Problem is here...
Now if i will go 2nd page. it is resetting the page.
my Problem is when click on firtColumn sort(by Name) it has to show 3rd page contents in 1st page. if i will go 3rd page, it has to show 1st page contents.
How to Handle this?
anybody any solutions. plz help me will be appriciated

Dim newTextBox As New TextBox
newTextBox.Location = New Point(x, y)
newTextBox.Size = New Size(sx, sy)
newTextBox.Text = someText
newTextBox.Tag = someTagValue
Me.Controls.Add(newTextBox)
This is the same way the Forms designer writes the code when you drop a TextBox (or whatever) on a form at design time.

Hello Friends,
I am facing a problem in copying a table from SQL SERVER to Access DataBase. I have identical tables in access database to and what i am trying is creating 2 datasets, one is connected to SQL Server DB and another one is connected to Access DB. Now when I use the "Copy" command of dataset to copy data from one dataset to another dataset and then updating the adapter it throws no error but access database doesnt reflects refreshed data.
Do you guys have some working code on this problem.
thanks in advance

Well, I've never had to do this. And, frankly, don't want to.
Off the top of my head, you can't do this between two different databases because the underlying database types are different. For instance, SQL Server supports the bit type, where Access does not. The Data/Time storage formats are different, different Integer types are supported, Currency, ..., yada, yada, yada. The Copy method will NOT translate this for you.
So, no, I'd say you can't do this using this method. You'd have to read each individual record and field from the source table, translate the data, then put the new data in an Update or Insert query in the Access database.
The other alternative is to construct a DTS job to do the export for you. This will, of course, depend on the Access file being put someplace where the SQL Server can write to it and you can pick it up after the job completes.

I am building a balloon tip and I need to be able to locate all rectangles so that when someone draws on the tip i can relocate it to be within the bounds of the tip.(I want to establish a new starting point (0,0)). It would make it easier for the user instead of having to figure out where 0,0 is and adjust for it. I am only able to do this with controls.
Whenever someone puts a control or draws out of the bounds it cannot be seen.
I am just tring to make it easier.
Can this be done
THANKS

You could add them as resources. But, you'll need to extract them back to the disk in order to use them.

You can use ILMerge[^] to combine compiled .Net assemblies. Its a command line program so you can just load up cmd and run something similar to the following (as long as ILMerge.exe is somewhere in your PATH):
ilmerge /out:MyExe.exe MainAssembly.exe ReferencedDll1.dll ReferencedDll2.dll That will combine MainAssembly.exe, ReferencedDll1.dll and ReferencedDll2.dll into a stand alone exe called MyExe.exe. This exe can then be distributed on its own.
Hope this helps 
Cheers,
Will H

You're trying to close a Modal form that isn't at the top of the z-order. In other words, You have a form that opened a modal form, that itself, opened a modal form. You have to close the forms in the reverse order that you opened them.

how can i set the session for my login page that no one is able to access the page directly.he/she must login first.

I think you are dealing with ASP or PHP related to a web site. If you do so, here is my advice:
You have to control every entry related to admnistration to your web site. It is likely create a sub procedure and check the session variable if it has a initiated value.
Sub Check_Security()
' check if someone is trying to get in the pages by directly typing the
' page name
If Session("Log_UserID") = "" OR Session("Log_MemberType") <> "admin" Then
response.redirect ("../quit.asp")
End if
End Sub
Check_Security() procedure should be in every asp or php (admin) related web pages (on top of the page). The example above shows how to control a user if he or she is a admin... You can change it vice versa...
I hopw that works out for you !
