    - .NET C++ SMTP question I have been asked to do the following: Create an application that will take an e-mail address entered by the user into a field and, once a button is clicked, will take that e-mail address and check it against the mail server for that address using SMTP to determine if it's a valid or invalid mailbox. Can anyone suggest a resource for doing the SMTP checking? Tag: Copying to clipboard using Ctrl-C or Clipboard.SetText Tag: 119705

    - The given path's format is not supported. I have a web page where a user can upload a .pdf document. When I test it on my machine and also from the live site, it allows me to upload a document fine. When a co-worker tries to use it, he gets System.NotSupportedException: The given path's format is not supported. When I try to upload the same document, no problems. Anyone know what the problem might be? Thanks. Tag: Copying to clipboard using Ctrl-C or Clipboard.SetText Tag: 119703

    - window.close problem Hi! On this URL is the example of my problem.... http://www.usa.canon.com/consumer/controller?act=RedirectAct&fcategoryid=313&modelid=9429&URL=http://www.usa.canon.com:80/consumer/controller?act=SecondRedirectAct&nav=second&fileURL=/app/pdf/slr/Rebel_brochure.pdf&type=DNLD As it loads, it starts to process the script and then comes to window.close that shows the dialog box asking user if it should close the browser window. Since I am using IE as control in .net 2.0 and using some extension to it found on codeproject site, I want to handle all browser UI with my dialogs, but unfortunately event that is supposed to be firing doesn't fire. It is WindowClosing event, that even has cancel parameter. My ideas: 1. find out if there is some hidden property inside Internet Explorer registry that would default the dialog box to yes or to no (no success there) 2. find if there is a way to use Navigate() to the url, then use some event that is fired after the document is loaded but before the script runs (no success there either) 3. make local proxy server that would filter out window.close from the script Am I missing something, please advise.

    - Finally, handling resizes and and MDI's scrollbar. Been trying to figure out how to resize forms indside an MDI Form, when the form itself is resized dynamically, to maximize and anchors do not help. The problem was getting the size of the scrollbars, and effecting the resize at the right time. For me, the answer was finding the MDIClient and AddHandlering its Layout event. MDIClient is the client area inside the MDI form, in my case, without a scrollbar, MDIClient.ClientRectangle.Width was 4 less the MDI.Rectangle.Width (must be two pixels for each of the MDI's borders). With a scrollbar it jumped to 20 (likely the scrollbar is 16 pixels wide). Getting the MDIClient (as found in the newsgroups) is done with a ForEach cycling through all controls in the MDI's control collection and finding the one with the type MDIClient. Should probably be index of 0, unless the user makes it an MDI in the code after other controls are added. The second thing was handling those scrollbars. That is done by the MDIClient's layout event, at which time, the scrollbars et al have been taken into account. Since the MDIClient is not there right away, the Handler must be refered to in the code. The declaration of the MDIClient's Layout event is the same as the MDI's Layout event. B.

    - Problems with ASP.Net 2.0 and JavaScript OK, Im working with a DataList in .Net 2.0, the code shows the list when the query has executed.

All string enums in the xml are availible in the vb code as strings. If I use the same tool today the code is different to that a year ago - especially the enums are different. Now I get Integer values for enums which are strings. I have to use .ToString to get the string value.

    - System.Version Hi All, I've searched the documentation and Google for an answer to this but to no avail. It seems that System.Version does not serialize to XML. I checked the documentation and this type is flagged as being Serializable, it has a default parameterless constructor, and I'm pretty sure it can be binarily serialized without a problem. On my example class I have a field as follows: Public MyVersion As System.Version I initialise this to a new System.Version(5,5,5,5) before serializing. After serializing it to an XML file using the XMLSerializer class all I get in my XML doc is "<MyVersion />" - this seems to imply that none of the fields in the System.Version class can be serialized into XML? Can anyone confirm this? Thanks, Alex Clark Tag: Copying to clipboard using Ctrl-C or Clipboard.SetText Tag: 119677

    - Async Sockets, pinned objects and .NET 2.0 Hi, I am migrating an application from .NET 1.1 to .NET 2.0. It is a network application that use asynchronous sockets intensively (with more than 300 active connections on average) With .NET 1.1 I had problems because the buffers used in the BeginReceive and BeginSend calls were pinned and prevented the heap to be compacted by the GC. I managed to solve this problem by allocating the buffers at the application start up using a buffer pool. Now, in the same application, compiled with .NET 2.0 the heap is heavily fragmented. I can see with perfmon that the pinned objects counter is about 4 times the number of pending asynchronous calls (it was exactly equal in .Net 1.1), so it seems that .NET 2.0 pins 4 objects for each asynchronous socket call instead of pinning only the buffer. This make senseless the approach of using a buffer pool (I get the same memory footprint in .NET 2.0 using the buffer pool or not using it). And the improvements done in .NET 2.0 in managing pinned objects are not good enough, so the situation became worse. Am I wrong with this conclusion? If not, Is there any workaround for this? or a way I can do that the asynchronous socket calls pins only the sending/receiving buffer? What other objects is .NET 2.0 pinning in the asyn socket calls?

    - Hashtable.Add fails Hi all, I want to assign a new key value to my hash table (okay, I use the Specialized.NameValueCollection, but this collection is based again on the HashTable). When the key already exists, then the value of the key shall be replaced. That's why I use the Add method which also replaces key values instead of Insert which fires exceptions when a key already exist. Now, I've got a very strange exception: ----SNIP---- System.ArgumentException: Das Element wurde bereits hinzugefÃ¼gt. SchlÃ¼ssel im WÃ¶rterbuch: "color_anchor_NavHeader2_all" HinzuzufÃ¼gender SchlÃ¼ssel: "color_anchor_NavHeader2_all" at System.Collections.Hashtable.Insert(Object key, Object nvalue, Boolean add) at System.Collections.Hashtable.Add(Object key, Object value) at System.Collections.Specialized.NameObjectCollectionBase.BaseAdd(String name, Object value) at System.Collections.Specialized.NameObjectCollectionBase.BaseSet(String name, Object value) at System.Collections.Specialized.NameValueCollection.Set(String name, String value) at System.Collections.Specialized.NameValueCollection.set_Item(String name, String value) at BOMAG.CorporateWebSite.DealerCustomizing.LoadDealerConfigurationSetting(String propertyName, DealerLookupModes dealerLookupMode) at _ASP.style_aspx.__Render__control1(HtmlTextWriter __output, Control parameterContainer) at System.Web.UI.Control.RenderChildren(HtmlTextWriter writer) at System.Web.UI.Control.Render(HtmlTextWriter writer) at System.Web.UI.Control.RenderControl(HtmlTextWriter writer) at System.Web.UI.Page.ProcessRequestMain() ----/SNIP---- The add method is called, it identifies the key as missing and that's why it calls the Insert method internally. Then, the Insert method wants to insert the key - but by whatever reason, the insert fails because the key already exist. Somewhere between the execution of the IF in the Add method and the key-insertion in Insert, the key must have been created. So, I can only imaging that another process (very normal for web solutions) might be more fast and inserted the key value in the meanwhile. Is this a bug or is it a feature? Thanks for any advise!

    - Help with registering AssemblyResolve event I am writing an application that uses a set of library assembly dlls that are located in a command line passed location. Originally, I tried to solve this problem by creating an AssemblyResolve handler and registering it very early in hte main function. The problem is that the application actually uses some of these assemblies. In particular, one of the classes (named MainWindow) derives from a class in the library. If the runtime attempts to create a MainWindow before the handler is loaded, then I have a problem. Fair enough. However, the way I understand the JIT, I thought it would not attempt to load dependent libraries until the class is used or a static call is made on that class. I made a seperate "Launcher" class that the main funciton and the handler, but I am still failing to resolve the assembly before I even reach my main function. I am reasonably certain that if I wrote an entire launcher assembly then this method would work, but I'm hoping there's a "cleaner" way to fix this problem. Has anyone ever run into this problem?

    - Gui threads (STA) and calling WMI Posting an issue for a colleague: They are having an issue w/ making WMI calls from a gui thread. Gui threads need to be on the STA and there is some speculation that WMI calls need to be on the MTA, how to mix both? ... The application is hanging on exit. When they break into the debugger, the thread on which it is stuck is in a 'WaitOne' call. The call stack is: mscorlib.dll!System.Threading.WaitHandle.WaitOne() + 0x57 bytes system.management.dll!System.Management.MTAHelper.WorkerThread() + 0x25 bytes I searched around a bit on the web, and found this article: http://discuss.develop.com/archives/wa.exe?A2=ind0306b&L=dotnet-clr&T=0&F=&S=&P=3961 It seems to imply that threads that make WMI calls must be MTA. And, Paul thinks that GUI threads must be STA. Many .NET controls are just wrappers on COM controls, which would seem to imply they must be STA. But, what about threads that are both GUI threads and make WMI calls? Or are both GUI threads and make MTA-COM calls? They can't be both MTA and STA... Any thoughts?

    - Unbox IL instruction question Hi, I'm referring to: http://msdn2.microsoft.com/en-us/library/system.reflection.emit.opcodes.unbox.aspx There's a lot of stuff here that doesn't make sense to me. This page states: A value type has two separate representations within the Common Language Infrastructure (CLI): A 'raw' form used when a value type is embedded within another object. A 'boxed' form, where the data in the value type is wrapped (boxed) into an object so it can exist as an independent entity. The unbox instruction converts the object reference (type O), the boxed representation of a value type, to a value type pointer (a managed pointer, type &), its unboxed form. The supplied value type (valType) is a metadata token indicating the type of value type contained within the boxed object. Unlike Box, which is required to make a copy of a value type for use in the object, unbox is not required to copy the value type from the object. Typically it simply computes the address of the value type that is already present inside of the boxed object. ________________ Now a few things: It mentions an "object reference" and a "value type pointer." What is the difference here? Aren't they both pointers? An object reference is an address where an object lives, correct? A value type pointer is what then? A pointer? A pointer is also an address where something (perhaps an object) lives, right? What to type O and type & refer to? Another question: "unbox is not required to copy the value type from the object. Typically it simply computes the address of the value type that is already present inside of the boxed object." It seems then that unbox which is supposed to return a value type is simply returning a pointer to what is inside the box. I thought value types were very simple: they contain only the actual data you're using. If you push the integer 6 on the stack, you don't deal with addresses at all, you simply put a 6 on the stack. right? so why is this unbox instruction able to avoid copying from the box and just return a pointer to what's in the box? Isn't that the exact same situation we were in when it was a boxed object? Thanks... -Ben Tag: Copying to clipboard using Ctrl-C or Clipboard.SetText Tag: 119598

I would like to remove the security walk above!! in C# I could tag my declaration like that: [System::Security::SuppressUnmanagedCodeSecurityAttribute] extern static void SomeCFunction(); but in managed C++ I don't declare the function, I just import the header and call the function. how do I avoid stack walk?

    - Detecting Battery Backup Notification I am setting up a couple of servers for an internal beta test of a web app. I want to implement a feature that would tell logged in users to log out should a power failure occur (and the servers are running on UPS batteries). Assuming I configure the Power Options so that "Notifications" are broadcast, how do I detect those notifications in my web app? I have search high and low for what these "Notifications" are but cannot find anything. Tag: Copying to clipboard using Ctrl-C or Clipboard.SetText Tag: 119560

    - Queued Components and TransactionScope Hi, I have an app that uses Queued Components. The queue is set as transactional and the transaction is set to Supported (I've also tried Required). Everything is running on the same box (tried XP and 2k3). In my app I wrap the queued component call in a TransactionScope. I'm using EnterpriseServicesInteropOption.Full in creating the scope. Right after queuing the component I intentionally throw an exception and don't complete the scope. The message stays on the queue and gets processed. This is a simplified version of what my program really does, which is call a database update within that same scope. When something fails I want the entire transaction rolled back; DB and MSMQ. What actually happens though is that the DB rolls back but MSMQ doesn't. I created the simplified version just to see if I could get MSMQ to roll back, but I can't. So what am I missing?

    - VB6 deployment through DotNet I know that DotNet's deployment functionality will allow very easy the ability to add a VB6 executable and/or DLL. My question is if there is a way that it can detect dependencies within that VB6 file? I know it does it for DotNet code but it doesn't appear to do it for VB6.

    - Discrepancy in DataGridView column order & databound DataTable Dear group, I'm currrently investigating a bug within a piece of our software whereby if a DataGridView (bound directly to a DataTable) is ordered by column headers (containing lookup combo boxes where the value is the foreign key of another table), although the DataGridView is ok, the DataTable becomes out of sync. In other words, I have a Grid of customers, and if a customer name column header is clicked - the data moves in the DataGridView, but previous data is still held for the original row positions in the DataTable. This throws off row calculations quite considerably, and is a particularly fustrating bug to debug. Any ideas are most welcome, and thanks in advance for any advice.

    - Using namespace from another project I have two projects, both build .exe. Project_2 declares an object that is defined in Project_1. At compile time I refer from Project_2 to Project_1 and it makes Project_1 namespace available to Project_2. Project_2 compiles and runs, but at runtime it requires Project_1 executable to be in the same folder. Otherwise it crashes. How can I make it so Project_2.exe runs in a different folder from Project_1.exe? I would prefer not to use GAC. I am using Visual Studio 2005, C#, Windows Forms. -- Gregory Khrapunovich Tag: Copying to clipboard using Ctrl-C or Clipboard.SetText Tag: 119548

    - [.Net 2.0] How to participate into a transaction ? Hi, I'm building a component that perform some operation and that is working. This component is runnig into the application app domain by now, but later, this component will be a distributed component that will perform operations which represent only a part of a whole process. Since during this process errors can occurs, I suppose I have to enable the component to participate into transactions. What are the requirements of my component to act as a optionnally transactionned component ? I use to surround my code with using(TransactionScope ts = new TransactionScope()){....} when I execute sql request. Will (or how) my component be using the ambiant transaction ? I hope someone can put on the way, or give me a sample and/or a pattern to reach my goal. Thanks in advance for any help. Steve Tag: Copying to clipboard using Ctrl-C or Clipboard.SetText Tag: 119547

    - Newbie Connection problem I have spent 3 plus hours looking at documentation and references. I have copied code and changed variables... but still nothing. Here is my connection string and scalar. Dim sqlConn As New SqlConnection("Data Source=*Server;Initial Catalog=*DBName;Integrated Security=SSPI;") Dim sqlComm As New SqlCommand(strSQL, sqlConn) sqlConn.Open() Dim strUserID As Integer = sqlComm.ExecuteScalar() sqlConn.Close() MsgBox(strUserID) The SQL statement is correct and runs perfectly in the query analyzer. It returns a 1 in SQL Server which is the correct result. However it returns a 0 whenever I try to access this data in my .NET windows app. Am I forgetting anything? -Lost on what to do next Tag: Copying to clipboard using Ctrl-C or Clipboard.SetText Tag: 119546

What is the difference between copying to the clipboard using Ctrl-C and
Clipboard.SetText? When I use Ctrl-C I get line feeds as I expect. When I
copy to the clipboard using SetText I just see little boxes (which I am
assuming is the carriage return or line feed). I am trying to copy text from
a RichTextBox control to the clipboard.

Thank you.

Kevin
