    - Customizing MSBuild I'm working on a big solution containing 12 projects. It takes hours (not realy, but you get the picture) to build and i'm looking for ways to cut corners and increase my "coding-not compiling time". To decrease build time, I created a SlimBuild configuration which only buildt the most necessary projects. This worked great in terms of build time, but as of now, its worthless because the loader project does not copy the dll which are not rebuild every time to the output folder of the loader project. The only dll's which are updated are the ones which are set to be build when i do my ctrl+shift+b. Sadly, it seems that the compiler does not check for newer versions of dll's other than the ones that are set to be build every time. I was wondering i there is a way to customize msbuild to manually copy all dlls in the solution to the output directory of the loader project as a post-build event?

    - Clickonce Prerequisites Order Hi Peoples, I am currently setting up the deployment for our product. The problem I have is that when running the clickonce install on a windows 2000 with no server pack machine I have a problem in that I need to install service pack 3 to install the 2.0 net framework. I want to automate this process in that when the install is clicked and the installer finds that it is installing on a 2000 box it will install service pack 3 and than install the .net framework. I have created a bootstrapper package to install the service pack and have tested this and it works fine. The problem i have is that when i have the 2.0 framework and the 2000 sp 3 prerequisites both selected it will not install because the 2.0 framework is loaded first and sees that the box is running 2000 without the proper service packs and kicks the user out of the install. Is there some way that I can order the prerequisites so that it checks the computer to see if it needs the 2000 service pack, than once thats sorted it does the install of the .net framework? -- Regards, Steve.

    - How can I access internal classes from another assembly? While working with Wintellect's Power Collections, I noticed that they have a unit test assembly that accesses internal classes in their power collection assembly. I thought the definition of "internal" was that you could not access an internal class from another assembly (without using reflection as a back door). I cannot find anything special that they have done, but cannot duplicate it. I must be missing something terribly simple about how assemblies work.

    - using unmanaged dlls from managed dll wrappers. Hi, I hope someone can direct me to the correct newsgroup if this one is not correct. I have a unmanaged C++ dll that I need to use from a C# client. Rather than use dllImport directly, I created a managed C++ dll (in the same solution). In this managed C++ dll, I added a reference (under references) to the unmanaged dll (it's listed under the project tab). I also had to #include the header file for the unmanaged dll in my managed code. Then I created a C# client (.exe.) in my solution to test this idea. In the C# client I simply added a reference to the managed C++ dll. All worked great and I was happy. Now two weeks later, I would like to use this stuff from a real project. From a C# class library (which is used by my C# exe), I call into my C++ managed dll. I of course had to add a reference to the C++ managed dll. Everything compiled. However, when I run, I get the following runtime error: An unhandled exception of type 'System.IO.FileNotFoundException' occurred in CSharpLibrary.dll. Additional Information: File or assembly name ManagedConverterWrapper, or one of its dependencies, was not found ManagedConverterWrapper is the managed C++ wrapper I wrote. I tried adding a reference in my C# class library to the unmanaged C++ dll using the 'Add Reference' tab. It did not work (got error saying could not add non DotNet dll) . Curiously, I was able to add a reference to the unmanaged dll to my managed C++ dll. Was that because it was within same solution or does C++ behave differently with respect to adding references. I also tried copying the unmanaged dll everywhere I could think of (bin/debug of C# class library and C# exe). No luck! My questions are: 1. When one uses a managed C++ dll that in turn makes use of unmanaged dlls, what else must one do to get things working? I.e. Compiler settings, additional references, file copying, etc. 2. Why did everything work fine when all the project where within one solution? Thanks in advance for any pointers, advice or references. Dave.

    - FileStream exception: unknown error Hi, Whenever a customer of ours runs our software on any of his laptops, we get an IOException with an Unknown Error (-1) message at every call to the System.IO.FileStream constructor. This is really annoying, as none of our other customers have this problem, and we have no information whatsoever about the error. I looked into the SSCLI code and apparently on the CreateFile an INVALID_HANDLE is returned, and a call to GetLastError returns -1. It has nothing to do with permissions of security, I think, since new FileIOPermission(secAccess, new String[] { filePath }, false, false).Demand(); (filestream.cs, line 263) doesn't throw an exception. I can understand nobody can give me a "This is it"-answer, but could someone please tell me how to debug a situation like this? This is driving me insane...

    - usercontrol in IE shows warning message. How to avoid? Microsoft .NET security warning Never enter personal information or paswords into a window unless you can verify and thrust the source of the request. mvendertaca@nospam.nospam I've created a usercontrol which is hosted in Internet Explorer. It with some action buttons. I could place all buttons on this usercontrol but I did not. When the user presses one of the buttons i detect some more action needs to be taken and open a dialogbox. using ShowDialog. But IE finds a usercontrol opening a dialogbox dangerous (Although the usercontrol could alsready have done anything because i have elevated its permissions using a strongname and such.) It changes the dialog icon to include a little exclamation mark and shows a balloon tooltip on this new icon stating: 'Never enter personal information or paswords into a window unless you can verify and thrust the source of the request. Souce: localhost' This is anoying, because it keeps on coming everytime the action is taken and the user has no possibility (it seems) to make this balloon not coming again and again. Can this dialog be avoided by asserting one of the permissionsets? I do not find one. Kind regards, Marc. Tag: Prevent framework 2.0 - when called through COM Tag: 110909

    - Waht is the fastest/bets? Outlook Object/CDO/Redemption/...? Hi, I'm using a thight integration with Outlook 2003 (with an Exchange server) in my VB.NET (2005) application. Until now I'm using the Outlook Object Model, but it appears to be very slow, and has some problems: - doing a Move changes the ReceivedTime of the MailItem - I can't use RichText in the MailItem.Body (only allows plain text or HTML) - some other stuff like having to use small 'tricks' to show the default signature in an email - ... So I'm looking to other ways to have an interactions with Outlook. What I basicly need to do is: - Move the currently selected mail to a specific folder, and write the data of it to a database (subject, entryid, sender, recipients, attachments, ..) - Create a new mail with a specific text, receiver, subject, attachements, and once it is send move it to a specific folder and write the same data to the database These things actually do work, but especially the first one takes too much time: on some clients more than 10 seconds!! Is their a way to speed things up? using CDO or Redemption or ...? What are the pros and cons of each way? Can they do what I need? Any help our hints would be really aprpeciated!

I've done some reading up and it seems that using ManagementEventWatchers is the way to go, yet using the code below in a test project, I find that inserting a USB drive triggers up to about 5 events instead of just the 1 I'm expecting. If anyone could point out the error of my ways that'd be great. Cheers Paul Taylor Imports System.management Public Class Form1 Inherits System.Windows.Forms.Form .. Dim query As WqlEventQuery Dim WithEvents watch As ManagementEventWatcher Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load query = New WqlEventQuery("Select * from Win32_DeviceChangeEvent") watch = New ManagementEventWatcher(query) watch.Start() End Sub Private Sub w_EventArrived(ByVal sender As Object, ByVal e As System.Management.EventArrivedEventArgs) Handles watch.EventArrived MsgBox("Event!")

    - Stop 0x000000E0 param: 0x00000001, 0x80000003, 0x00008080, 0x80e92000 Hello. Ok. I have the job of fixing an ibm thinkpad 600e model 5A0 and have a weird problem. I was running xp quite successfully albeit slowly without any issues until I turned it on and now I am getting a stop error. Stop: 0x000000E0 param: 0x00000001, 0x80000003, 0x00008080, 0x80e92000 I am a bit techy and have the job of fixing it :( I know that the stop error error 0x000000E0 refers to the ACPI bios. However it works in safe mode and other os and indeed xp until recently. The bios version is : INET24WW, 05/24/1999 I know this could be updated but I hate the idea of updating the bios (in case it goes wrong) and it worked before. However, When running a test on the system board using the bios it reports an error: DEV 001 ERR 91 FRU 3610 I am not too sure what these errors refer too but believe it's something to do with the battery. Besides, if there was an hardware error inside the bios wouldn't it also fail in safemode? Another sceptical moment! Of course, I have tried running msconfig and disabling all startup items and have disabled all options in win.ini, boot.ini etc. I have managed to do this from safe mode. I cant run sfc /scannow cos its in safemode or system restore as it generates an error, indeed getting into the event logs results in an error so I have the stop errors to work from. The people who owned this machine also has a lot of documentation on here. There is no built in nic card and I cant install anything else until I sort out the other stuff. The only real option I could do is use a ubuntu live cd and hope I can mount it and copy stuff over!!!!!! So, if anyone can provide a solution that does not require reinstalling, it would be greatly appreciated. Cheers John -- www.integrated-dev-sol.co.uk Remove 123 from email address to reply.

    - Making a Winforms app behave like a Console app I am attempting to add a "console mode" to my Winforms app. My intention is that when I start the app with a special switch (for example "myapp.exe /batch") to does not launch a graphical UI but instead just displays console messages. My first guess was to simply change the Main method of the startup class to do something like this... if (batchMode) { Console.WriteLine("Now in batch mode"); ... } else { MainForm.Run(); // Launch graphical user interface } Unfortunately, it looks like my app does not behave like a real console mode app in either case. When I execute the app from the command line, the app returns immediately and text output by Console.Write() does not appear anywhere. Setting the app as a Console mode application does not give me what I want either. With this mode, a big black console output box appears even when in "GUI mode". Is there a way to build one executable that supports both modes and dynamically switches at runtime? Tag: Prevent framework 2.0 - when called through COM Tag: 110881

    - Event name from EventHandler or Delegate? I have an application in which I need to fire an event from some class other than the one that has defined the event. I am trying to do this by finding the delegate associated with the event in question, and then by calling GetInvocationList() and invoking each EventHandler in turn. And although I've found some nice links to back-door techniques on how to retrieve a delegate for a given event, those techniques don't seem to work for me. I've figured out an alternative method, but it's not quite working the way I want it to...yet. Alex Feinman (http://www.opennetcf.org/PermaLink.aspx?guid=4cf118ee-5668-452e-af2c-f3a0c6d43a7f) and others have suggested a technique where you cycle through the private fields of a type looking for one that has the same name as the event of interest. For example, to find the delegate for the Click event for button1, and then emulate the button-click event on that button: Type t = typeof(Control); FieldInfo fi = t.GetField("Click", BindingFlags.NonPublic | BindingFlags.Instance); Delegate handler = fi.GetValue(button1) as Delegate; foreach (Delegate d in handler.GetInvocationList()) { d.Invoke(button1, new EventArgs()); } Only trouble is, this doesn't work for me. I can't find this private field. What "almost" works instead is something like the following, but it returns *all* delegates, and by, extension, all event handlers, for the associated control, not just the ones associated with the Click event or some other event of interest. So my question is, given an instance of an EventHandler or Delegate, is it possible to determine which Event that EventHandler or Delegate is associated with? // button1 is defined as a Button, and it has added an EventHandler // to the chain of handlers that handle the Click event. It has also // defined some handlers to handle other events and has added those // handlers to the chain of handlers associated with those other // events. Every non-null delegate for the control is returned by // findDelegates(), not just the Button.Click event delegate. ArrayList allDelegates = findDelegates(button1); // The following will cycle through ALL delegates. not just the ones // associated with the Click event. This is not good.... foreach (Delegate del in allDelegates) { Delegate[] theseDelegates = del.GetInvocationList(); foreach (EventHandler thisHandler in theseDelegates) { thisHandler.Invoke(buttonDemo, new EventArgs()); } } // What I would like to do: // Delegate buttonClickDelegate = findDelegateFor(button1, "Click"); // and then invoke this delegate's handlers as above. ... protected ArrayList findDelegates(object o) { ArrayList rc = new ArrayList(); // Event-handler information for a given instance // of an object should be accessible through a private field // of type EventHandlerList. And this field probably won't // be defined for the current class type of object o. // The field will probably be defined as part of a base // class that is buried several classes deep in the // inheritance chain. // findFieldType will recurse through the type tree for // the caller-specified object until it finds a field of type // EventHandlerList FieldInfo f = findFieldType(o.GetType(), typeof(EventHandlerList)); if (null == f) { return rc; } EventHandlerList ehl = (EventHandlerList)f.GetValue(o); if (null == ehl) { return rc; } // The EventHandlerList class doesn't expose what we need. // We need to get to the private fields...to the contents of the // linked list that is contained within the class. Each entry in // the linked list is of type ListEntry (a private nested class // apparently defined within EventHandlerList) and represents // one delegate. The event handlers for that delegate can then // be accessed using the publicly visible GetInvocationList() // method. FieldInfo headFieldInfo = ehl.GetType().GetField("head", BindingFlags.NonPublic | BindingFlags.Instance); if (null == headFieldInfo) { return rc; } object headField = headFieldInfo.GetValue(ehl); // findDelegate will populate the caller-supplied ArrayList with // all delegates in the linked listed headed by headField. // What we really need is a way to get only those delegates // associated with a specific event. findOneDelegate(headField, ref rc); return rc; } /// <summary> /// Walk through the linked list represented by the caller-supplied /// ListEntry object and extract delegates from that list. /// Each event exposed by a given control is represented by one linked /// list entry. There may be multiple delegates to handle the event, /// but those delegates are retrieved using the GetInvocationList() /// method and not by using this back-door stuff. /// </summary> /// <param name="o">A linked-list entry of type ListEntry</param> /// <param name="delegateList">A reference to a delegate list ArrayList /// that is recursively populated</param> protected void findOneDelegate(object o, ref ArrayList delegateList) { if (null == o) { return; } object next = null; foreach (FieldInfo fx in o.GetType().GetFields( BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance)) { object thisObj = fx.GetValue(o); // thisObj is of type ListEntry. It has 3 fields: // next -- the next ListEntry in the linked list, // key -- an object. Obviously this identifies the event, but how?? // delegate -- a delegate if (fx.Name.ToLower() == "next") { next = thisObj; } if (fx.Name.ToLower() == "key") { Trace.WriteLine("Key type: " + thisObj.GetType().Name + "; hashcode: " + thisObj.GetHashCode().ToString()); } if (fx.FieldType.Name.ToLower() == "delegate") { delegateList.Add((Delegate)thisObj); } } if (next != null) { findOneDelegate(next, ref delegateList); } } Tag: Prevent framework 2.0 - when called through COM Tag: 110869

    - Changing selected index of dropdown is not reflected when posted back? Hi all, Using .Net Framework 1.1 (with latest patch), I have a page with your typical DropDownList control. There is logic that causes the selected value (or selected index) of the drop down to be reset or changed via javascript. This happens great on the page, but when the I try to access the DDL.SelectedValue on the server, the value is always the option that was initally set. Even if I manually select an item prior to the javascript "re-selecting", the selected value is the initial value. Any ideas?

I have a .net program written in 1.1, that doesn't work in .net 2.2.

We use it from a non-dotnet application, so it is called through a COM
interface.
The problem is that when it is called through the COM interface, it runs in
2.0 and fails.

How do I prevent that?

Off the top of my head: Set it up as an app so you can add a config. Set the
config to require runtime 1.1.

In your non .NET program, you can first bind to a specific version of
.NET Framework using the unmanaged hosting api, e.g.,

ICorRuntimeHost* spRuntimeHost = NULL;
HRESULT hr = CorBindToRuntimeEx(
L"v1.1.4322",
L"wks", //Request a WorkStation build of the CLR
STARTUP_CONCURRENT_GC,
STARTUP_LOADER_OPTIMIZATION_SINGLE_DOMAIN,
CLSID_CorRuntimeHost,
IID_ICorRuntimeHost,
(void**)&spRuntimeHost
);
if (SUCCEEDED(hr))
hr = spRuntimeHost->Start();

This will force v1.1.4322 to be loaded. Make sure you do this before
any other .NET stuff coming up. I have used this on remotesoft tools,
and it work well for us.
