Hi All,
I've been looking around CP and the .NET for a decent .NET performance profiling tool, does anyone have any links for their personal favourites? I'd like to use Ants Profiling but I can't really afford it at the moment!
EDIT: Forgot to mention that I need this for .NET 3.5 SP1
Cheers,

You could use free Microsoft CLR profiler [^]
or AMD code analyzer [^],which is free tool too.

Hey,
Thanks for the links, I didn't even think about AMD ...
Thanks!

Unfortunately Intel Vtune has free personal edition for Linux only.According to me it's the best profiler in the market.

I'm building a web based api suing the usps delivery confermation api specs. i have build my user forms for which the user inputs the name and address for the address label. when i click on the submit button it builds a xml file called xxx.xml i then need to transfer the contents of the file over https to the U.S.P.S. with a Username and Password. usps processes the xml and responds with an xml that contains the shipping label to be printed. i was never really any good at programming i can make the connection to usps in http but i'm having problems passing my xml file. and when i do how do i get the reply to show. here is a list of my code for the trasport layer.
Dim filename As New XmlTextReader("ShippingRequest.xml")
Dim url As String
url = ("https://secure.shippingapis.com/ShippingAPITest.dll?API=DeliveryConfermationv3&XML=<DeliveryConfermationV3.0Request USERID="450PROFE2590"
Dim ourUri As New Uri(url)
' Create a 'WebRequest' object with the specified url.
Dim myWebRequest As WebRequest = WebRequest.Create(url)
' Send the 'WebRequest' and wait for response.
Dim myWebResponse As WebResponse = myWebRequest.GetResponse()
' "ResponseUri" property is used to get the actual Uri from where the response was attained.
If ourUri.Equals(myWebResponse.ResponseUri) Then
Console.WriteLine(ControlChars.Cr + "Request Url : {0} was not redirected", url)
Else
Console.WriteLine(ControlChars.Cr + "Request Url : {0} was redirected to {1}", url, myWebResponse.ResponseUri)
End If
Response.Write("<script type='text/javascript'>detailedresults=window.open('labelshow.aspx');</script>")
' Release resources of response object.
myWebResponse.Close()
if anyone could help it would be appreciated i will be honest i am somewhat lost.

Instead of just closing the response, you need to read the data from it. The code will look something like:
Using reader As New Xml.XmlTextReader(myWebResponse().GetResponseStream())
End Using
myWebResponse.Close()
PS: next time, enclose your code in a pre block by hitting the "code block" button and set the language to vb (<pre lang="vb"> ) to get proper highlighting.

Hi everyone,

Its creating client server apps for cyber cafe, so i need to lock( calling the windows form which shows up with backgroud screen) from server but I can't figure out how to do this.

Hi All,
I created a simple application in C# that displays a message when a button is clicked. I want this app. to be updated from a network drive, the same network drive that it was published from using ClickOnce.
In the Publish --> Updates window of the apps properties, it's set up so updates are checked "before the application starts".
After a modification is made to the application and I re-publish it the updated files are sent out to the users machine along with an updated very of the setup.exe file.
However, when the user starts the application from the start menu they aren't informed that an update is available and the old version of the application is ran.
The start.exe file can be ran and the new version installed then, but this isn't what I want the user to have to do. Shouldn't the user be informaed of the updated version when the app is ran?
Any ideas would be greatly appreciated.
Thanks,
Mel

Hi,
I've got some C++ code to convert to C# and I'd prefer the C# to be as similar in design to the legacy code as possible (not my original design).
Currently, I'm not having much luck finding an equivalent to WSAWaitForMultipleEvents() that lives in the managed world. Also, the current architecture doesn't allow for a higher-level repackaging with a C++/CLI.
Could anyone point me towards it if I'm just not seeing it in MSDN after staring at the screen for too long, or alternatively put me out my misery so I know I've just got to go with a rethink and rework and new time estimate.
Thanks v. much in advance,
Kev

How about something like Socket.Select()[^]?
A train station is where the train stops. A bus station is where the bus stops. On my desk, I have a work station....

You gave me a brief glimmer of hope there that I hadn't read the docs properly and that it was something that obvious, but no.  Socket.Select() does only work with sockets.
I've given up now to be honest. I'll go with Socket.Select() with an internal control socket that, when data is read from it, is the signal to close down the main socket.
Not ideal, but it's a close enough workaround that it's still clear what's happening in the ported code even though the events have been swapped for sockets. As being close and preserving the overall code structure is what I've been asked to do, it's good enough.
Thanks very much for the response anyway!

In fact I don't know where this idea to look at Socket.Select() comes from.
When I read your post and the documentation again, nothing mention socket!?! 
Anyway, how about: Semaphore[^], or multiple call to ThreadPool.RegisterWaitForSingleObject[^]?

You're closer with Socket.Select rather than the others which work on WaitHandles. I'll look into getting a WaitHandle-based object associated with a socket so I could use the regular WaitForMultipleObjects but the client's happy with the socket-workaround I told in last mail.
Thanks again.

On Windows, WSAWaitForMultipleEvents is the same as WaitForMultipleObjectsEx().
WaitForMultipleObjectsEx() in .NET is WaitHandle.WaitAny().

I'm almost there.
The problem: Using smo, I'm having trouble re-creating a DefaultConstraint on a column after dropping it.
Where this stems from: I need to change a column from nvarchar(x) to nvarchar(max).
(The ms help is useless, showing no examples for working with default constraints. No searches show people using smo to solve this.)
The conceptual problem is that you can't change a column's size if a "DefaultConstraint" exists on the column. You must drop the DefaultConstraint, then change the size of the column, and then re-create the DefaultConstraint.
Variables not shown: The variable "AColumn" below has been populated with a smo column object (Name:"SsGradeString"), and the variable "Size" is the desired size to change the column to.
The error occurs on AColumn.AddDefaultConstraint(DName), error message:"Column SsGradeString already has a default."
I tried doing Table.Alter, Column.Alter, DefaultConstraint.Alter (after the .Drop), but I get: "Cannot access properties or methods for the Microsoft.SqlServer.Management.Smo.DefaultConstraint '[DF_ADVSessions_SsGradeString]', because it has been dropped."
'preserve existing values for re-creation of DefaultConstraint
'NOTE: AColumn is the column we are working with and Size is the new size to set.
Dim DName As String = ""
Dim DText As String = ""
Dim DefaultConstraintWasThere As Boolean = False
'remove DefaultConstraint if it exists
If AColumn.DefaultConstraint IsNot Nothing Then
DefaultConstraintWasThere = True
DName = AColumn.DefaultConstraint.Name
DText = AColumn.DefaultConstraint.Text
AColumn.DefaultConstraint.Drop()
'tried doing various "Alter"s here but none work,
'citing that the DefaultConstraint's properties cannot be accessed.
End If
'make the desired change to the column property
AColumn.DataType.MaximumLength = Size
'recreate the DefaultConstraint if there was one
If DefaultConstraintWasThere Then
Try
'error is occurring here
AColumn.AddDefaultConstraint(DName)
AColumn.DefaultConstraint.Text = DText
Catch ex As Exception
Stop
End Try
End If

I had the same problem and I found a solution to this.
Our codes are exactly same.
Steps should be like this.
1) Drop constraint
2) Refresh Column
3) Change column data type
4) Alter column
5) Recreate default constraint
As you can see you are missing step 4.
This is why you are getting an error.

I've been hacking at this problem for a few month off and on and I can't seem to find a solution.
For parallel computing reasons it is necessary to open up and manage multiple instances of an application (CATIA) get be able to get them through the COM. The problem exists that you can only obtain the first register object in the running objects table with the standard GetObject methods.
My plan was to build a windows service that would be available to my applications through COM and manage the multiple instances of the CATIA application. This way any application started by any user should be able to get the windows service and then the CATIA applications from it. Right?
I first tried this in VB.NET but found out that my VB.NET applications couldn't use the VB.NET dll through the com (or I couldn't get it to work). So I'm now working in C# but I am still having troubles accessing the dll through the COM. I know the dll is being initialized and is running but when i try to test it using VBA in excel using the GetObject method. I can not get the Active X object. I've tried registering the dll in the ROT when initialized but it does not help. Am I missing something or am I wasting my time trying to get this to work.
I've had something similar working before, VB.NET executable with a VB6 wrapper (ActiveX executable). It worked fine alone on the machine but when trying to get the wrapper from a executable started by a cueing system (condor) it would fail to get the Active X object. I was hoping that if the dll was started by the system (windows service) any user could access it. Is this thinking correct?
Thanks,
SC

Hi
I am quite new in protecting code against hackers. I know that much to obfuscate the the .NET assemblies, but my questions are:
Which is harder for hacker: Reverse engineering the optimized x86 code or obfuscated .NET assembly?
How much extra protection does the standard anti-hacking approaches(checking the correct serial code in different places in code, adding dummy code to serial validation methods, using unmeaningful method names...) add to the obfuscated code.
Thank you for your time.

1 - It would be Reverse engineering the optimized x86 code.
2 - I am not a proponent of obfuscation. IMO, obfuscators will just rename classes,methods and variables to some hard to read names.
Here[^] is a good article in which Jon Skeet shares his views on obfuscation. Its worth reading.

Hi all,
I have this .NET 2.0 application. At several points during the application it asks the user to load a picture from their computer. Basically the code uses an open file dialog box to get the path and then copies that picture from that path into a section in my program's folder. Works great on my XP Pro development machine and on Vista. And it works great if the user is selecting a picture from their desktop.
However, if the user goes to My Computer and then clicks on My Pictures the program bombs and "locks up" (according to the user). I can't recreate the error here but I've managed to capture the sequence. I'm pretty sure both of these errors hit when the system "locks up". This also happens if they go to any other folder's subfolder.
I have no idea how to overcome this or what is even causing it or what to even search on. Help?
