    - File or assembly name X, or one of its dependecies, was not found with Dialogs I have a project that's part of a larger ap. I do save dialogs and prints, print previews, etc. Whenever I pull up a SaveDialog and then leave my dll (ie exit to go to the main menu) and try to go back in to my dll I get "File or assembly name MyDll.dll, or one of its dependencies, was not found." Any clue? I ONLY get this message when the SaveDialog is brought up. Thanks... Tag: Converting string to Keys enum value? Tag: 82240

    - Hi, a very important ASPNET permissions problem i need to make it clear Suppose that i have these paths in my server with these permissions: D:\httpdocs\ Allow: Everyone - full control (inherited from D:\) D:\httpdocs\host1\ Allow: Everyone - full control (inherited from D:\), ASPNET - full control D:\httpdocs\host2\ Allow: Everyone - full control (inherited from D:\), ASPNET - full control both D:\httpdocs\host1\ and D:\httpdocs\host2\ are also the document roots of the IIS hosts, each folder for one host. if i have some ASP.NET pages inside host2 folder, and use some asp.net System.IO to access file systems, or use other classes for other works, then, can i access host1 folder's resources from host2 by pass the parent folder? how will it be safe for every IIS host document root directories, so that make every host can access it host's resources only and really independent ASPNET permission for each folders?

    - SP1 Failure To Install Went to install "Microsoft .NET Framework 1.1 Service Pack 1". During install, had pop-up declaring failure to install one of the mscor*.dll files. Clicked OK. Install then hung. Used Task Manager to kill IE. Restart IE. Now install will not even start. What to do? Thanks. System seems ungodly slow, especially OE 6.0, since WinXP SP2 installed.

    - StringToObject Imagine a project I've got two dll's referenced, dll1 and dll2 within some function of my project i want to use a function out of dll1/dll2 Normally you then would put in the function: Function fncSomeProjFunc as int dim myobj as new dll1 (Make the functions of dll1 available inside this function) dim myobj2 as new dll2 dim sResult as string dim sResult2 as string sResult = myobj.SomeFunctionwithsResultAsReturnValue sResult2 = myobj2.SomeFunctionwithsResultAsReturnValue return 1 end function Now what i want is this Function fncSomeProjFunc(byval sDllToCall as String) as int . .. ... .... end function sDllToCall is either "dll1" or "dll2" being the NAME of the object that I have to declare. How can I use sDllToCall to declare an object? If you for example look at it the other way around, dim myobj as new dll1 msgbox (myobj.toString) would give "dll1" so maybe there is some function like myobj=sdlltocall.StringToObject or something like this? Posted this question elsewhere too, but no one seems to be able to help me out here. Thanks for the help Tag: Converting string to Keys enum value? Tag: 82225

    - Yes, you can install .net updates After encountering an update problem relating to both versions of Microsoft .net framework, I happened to visit windows update newsgroup and dotnet newsgroup and found every other person was having this problem. Incidentally this problem had happened with them after they had installed xp sp2. After a lot of browsing on Google and Microsoft knowledge base articles, I found the only solution to the problem was uninstalling both versions of .net and reinstalling them again. Interestingly sp2 had done enough damage to not allow repair of these programs. Now uninstall was another bigger problem, but thanks to the following knowledge base articles: - 1) Microsoft Knowledge Base Article - 320112 --- For removing Microsoft .NET Framework 1.0.3705 2) Microsoft Knowledge Base Article - 824643 --- For removing Microsoft .NET Framework 1.1 And then I got stuck on using Msizap.exe utility, which wanted me to download Microsoft Windows Installer Software Development Kit (SDK). I accordingly went to the site for the download but found out that it was a pretty big job as it included other compulsory downloads. I failed after numerous tries to download as the site didn't allow using any download managers and using dial-up for huge downloads is definitely a problem. And then I searched for Msizap.exe utility on the net after I found out that sp2 supported this tool. I found it here: - Referrer http://www.google.com.pk/search?q=cache:7Iu8UFkOULQJ:www.extorr.com/software.htm+download+Msizap.exe+&hl=en I then used it separately for both the versions of .net (as you can also find different commands for both versions in the above referred knowledge base articles) A reboot and again the installation failed (I was attempting install from the newly downloaded redistributables) And then I attempted a repair from the run command also mentioned in these knowledge base articles, after which, interestingly enough, the installs (both) succeeded. Another visit to the windows update site followed and the updates completed successfully. I am happy that I am out of this quagmire but I wonder how many other problems sp2 will unfold in future. For those who are prompted for the location of netfx.msi after trying to install .net, they can extract it from dotnetfx.exe and then browse to that location. To do this, download dotnetfx.exe or locate it on your local hard drive or a CD. Then, from a cmd prompt run the following: c:\dotnetfx.exe /t:c:\temp /c. You can substitute any folder you want for the "c:\temp" parameter. This will extract netfx.msi to c:\temp. I hope this helps. Tag: Converting string to Keys enum value? Tag: 82221

    - Memory consumption in the .NET framework Hi, this may be a simple question and I'm sure it's answered somewhere in the docs, but I haven't found it so far. When running a simple .NET application, Task Manager reports that it needs about 10MB RAM. Depending on what libraries are used, this may be more or less. This is what I expect for the first time, because the .NET framework libraries are loaded into memory. Now, when starting the same app several times, Task Manager reports 10MB RAM usage for each started process, which I don't understand. I have two explanations for it: 1. Task Manager does not report the correct memory usage 2. The .NET framework libraries are loaded into each process So far, I haven't cared about it, but I'm developing a product consisting out of some standalone applications, Office Addins, Smart Tags, Smart Documents, Local Web Services running an Office Research Provider and so on, so 5 - 10 processes will be started. If the .NET Framework is loaded into each of these processes, it will need 100MB of RAM or even more just for copies of the Framework. Is that a correct assumption? If yes, is there any compiler or linker switch to share the same instance of the .NET Framework? Thanks Michael Tag: Converting string to Keys enum value? Tag: 82220

    - Threading problems with COM Interop I am using a third party COM componenet which is not thread safe in a .Net web application using Interop. When two threads (two requests) are trying to access the componenet it is giving an error and crashing. It works fine if the request is made only one at a time.

    - Need help passing multiple arguments to an external executable. This is a very simple question, but cant figure out a way to do it. I want to know how to pass multiple parameters as arguments to an external process. I want to call an exe with following arguments :- MyApp.exe "C:\Some Directory\File.txt" /A /T . But the Process.Start or the StartInfo.Argumnets only let you give one string as an argument. Therefore it is not possible to pass a set of arguments like I want (one argument having double quotes). When I pass the above in one string the argument is given as "C:\Some Directory\File.txt /A /T" to the application which is wrong (the application take it as a one parameter and tries to treat is as a file). How can I do it ? Any help greatly appreciated. Tag: Converting string to Keys enum value? Tag: 82196

    - Optimization Help Needed How could I optimize the following method, whose purpose is to concatenate two byte arrays? public static byte[] ConcatBytes(byte[] a, byte[] b) { byte[] result = new byte[a.Length + b.Length]; uint i; for (i = 0; i < a.Length; i++) { result[i] = a[i]; } for (i = 0; i < b.Length; i++) { result[i + a.Length] = b[i]; } return result; } You see, my program uses this method, and to it, it passes two very large (perhaps in the hundreds of megabytes) byte arrays. This method takes MINUTES to run in this case. Tag: Converting string to Keys enum value? Tag: 82184

    - 1.0 SP 3 & SecurityException I have an application which is a EXE running as an NT service. It accesses an assembly (a1) which in turn accesses types defined in another assembly (a2). All was fine before SP3. Once SP3 is installed, I'm getting SecurityException whenever a1 wants to access types in a2, getting "Request for permission of type xxx failed". Everything is installed local so they all have FullTrust. One more piece of information. The types in a2 are all enumeration if that makes any difference. I caught the SecurityException and examined it, but it didn't give me much information. The PermissionState property is empty and PermissionType is null. Anybody knows if this is something changed/broken in 1.0 SP 3?? Thanks a lot. Tag: Converting string to Keys enum value? Tag: 82172

    - Net Framework 1.1 SP1/VS.NET 2003 SP Question When I do a windows update I noticed that the Net Framework 1.1 SP1 is available. The question I have is, does that mean that there is a SP available somewhere for Visual Studio.NET 2003? I would think that a SP for both would be required if there are changes to the Framework! I found several early articles on the internet which seem to support this belief; and stated that both the framework and 1.1 service pack were being coordinated with XP's SP2 rollout. However, since the early articles I have not been able to find anything on the Visual Studio.NET 2003 Service Packs! Any ideas? Thanks! Jim Tag: Converting string to Keys enum value? Tag: 82169

    - Is AxImp broken in SP3? Hi, I'm experiencing problems with AxImp.exe since installing framework 1.0 service pack 3. When I try to run AxImp I get: AxImp Error: Invalid Primitive Type: System.Reflection.Missing. Only CLS compliant primitive types can be used. Consider using CodeObjectCreateExpression. If I run AxImp with the /source option I get: AxImp Error: The process cannot access the file "....cs" because it is being used by another process. The errors only occur for one of our OCXs, the others work fine. It definitely seems to be related to the service pack. If I reinstall the framework it works, but if I then install SP3 it breaks again. Is anyone else experiencing this problem? Is there a fix or workaround?

    - Types vs. Attributes We want to be able to load the classes from a directory that derive from a particular base class. So the question is whether attributes for each deriving class will help us in finding these classes faster or not? We currently have attributes and use those, but it seems very slow to go through all the assemblies and try to get all of the attributes from there. I'm looking for a way to speed this up and wanted to know if anybody is doing something similar and had any pointers as far as speed. Lance Johnson Tag: Converting string to Keys enum value?

    - Reading data from a Socket I have coded a method which reads data from a socket in chunks of 2048 and concatenates those chunks into a string before returning the string to the caller. Almost all the time this code works perfectly well. Occasionally, for a reason I've yet to determine, the returned string seems to be truncated at 2920 characters. This causes problems in another part of my app because the string is Xml, which then fails to be loaded into an XmlDocument object. The code for the method is: Friend Shared Function ReadAllDataFromSocket(ByVal reciever As Socket) As String Const BUFFER_SIZE As Integer = 2048 Dim buffer(BUFFER_SIZE - 1) As Byte Dim bytesRead As Integer = BUFFER_SIZE Dim sTemp As StringBuilder = New StringBuilder(BUFFER_SIZE) Dim DataRead As String = Nothing ' Loop until all data has been read. While (bytesRead = BUFFER_SIZE) ' Read this chunk of data. bytesRead = reciever.Receive(buffer) ' Check that some data was read. If bytesRead > 0 Then ' Add this data to the string builder. DataRead = Encoding.UTF8.GetString(buffer, 0, bytesRead) sTemp = sTemp.Append(DataRead) End If End While ' Return the string to the caller. Return sTemp.ToString() End Function I tried recoding the method so that it reads the data all in one go, using the Available propery of the socket to determine the buffer size. However Available seems to be very unreliable and I've seen many people recommend avoiding it. Does anyone have any ideas as to why I get this problem, or can anyone suggest an alternative way of getting the data out of the socket? Thanks, Ross Tag: Converting string to Keys enum value?

    - Problems with XP style in Windows forms after installing .NET 1.1 SP1 Hi, after installing the SP1 for the .NET Framework 1.1, I have one Windows form that does not display the push buttons in XP style anymore. It worked without problems before and all other controls still have the XP look and feel. Just to make it sure, I verfied that the FlatStyle property is set to System and since yesterday the application looked great. Now it's poor because of a mix between the XP and the classic Windows style. I have other applications that still show the XP style buttons and I'm using the same technique in all applications (as described in KB830033, which so far worked perfectly in COM Addins and in native Windows applications too). Furthermore, I put the classes listed in KB830033 into an assembly that resides in the Global Assembly Cache, so I'm really using the same code in all applications. I don't see any reason why this single application does not display the XP buttons, but it definitely happened after installing SP1. I'm running Windows XP SP1 with all important hotfixes, but have not yet decided to install SP2. Does anyone encountered the same problem and may even have an idea how to fix it?

    - sqlserverCE sdf Hi Is there a way to generate a sdf -file on a PC, and move it for the SQLServerCE -device for usage there? I've got aprox 100 000 records to insert to the sdf -file, and have built a webservice for fetching chunks of records, inserting it to the sdf. This process takes hours. I guess overhead in Webservices to be the cause, and figure a TCP sollution would speed things up. However, doing all of this - serverside would be the quickest I'm sure. Using a pocketPC/winCE emulator on the server, generating sdf would do the trick I guess. But smells messy. Thanks, Finn Tag: Converting string to Keys enum value? Tag: 82112

    - dll's in VSNET2003 Compact Framework not registered Hi, After reinsalling VSNET2003 to a new path on my harddrive, the dll's in the Compact Framework are nor re-registered. One of my coworkers experienced the same problem with uninstalling and thereafter installing VSNET2003 to a new path on the harddrive. It is the VSNET2003 installation that "forgets" to re-register the Compact Framework dll's to the new path. His only solution was reinstallation of winXP and thats not an option in my case. OS: Windows XP + SP1a + alle updates I have tried: - uninstallation of VS NET 2003 + manual clean up + installation again - repairs of VS NET 2003 - extern installation of NET Compact Framework 1.0 SP2 - gacutil - but couldnt locate the Compact Framework... - MS RegClean.exe to secure clean up after uninstallation. That provoked Bluemoon!! I cant spare much more time in investigating why this happens, and are quite new to VSNET. I still have Java though - that always works, but I liked the Visual Studio environment to develop in. Can anybody help?

    - Globalizing declaration of OleDbConnection and OleDbCommand Hello. I'm working in C#. I have a form in which I bind data to a grid inside the Page_Load method (constructor? sorry, don't quite have the lingo yet) The form also includes a textbox. Depending on what the user types into the textbx, I repopulate the grid, i.e. rebind new data to it. I would like not to have to include the following two lines in both Page_Load and in the event handler I wrote for the text box: OleDbConnection MyConnection = new OleDbConnection OleDbCommand MyCommand = new OleDbCommand(); I'm looking to broaden the scope of these declarations to cover both of the above situations, but don't quite know where to put the declarations. Thoughts? Thanks so much, Google Jenny *** Sent via Developersdex http://www.developersdex.com *** Don't just participate in USENET...get rewarded for it! Tag: Converting string to Keys enum value?

    - Metafile problem I am having a problem using DrawImage to scale metafiles. Here is what I am doing: Metafile mapImage = new Metafile("C:\\image.wmf"); If I draw the entire metafile it draws correctly: g.DrawImage(mapImage, 0, 0); If I try to scale the metafile into the graphic, it does get scaled correctly but tho origin is moved so what gets drawn in position 0,0 is not position 0,0 in the metafile even though both rectangles have 0,0 values. g.DrawImage(bitmapMap, new Rectangle(0, 0, bitmapDest.Width, bitmapDest.Height), new Rectangle(0, 0, mapImage.Width, mapImage.Height), GraphicsUnit.Pixel); In fact the above statement SHOULD display the entire metafile but it only displays a portion on the lower right corener of the metafile. Also, if instead of using a metafile, I use a Bitmap, then I don't have this problem (i.e Bitmap mapImage = new Bitmap("C:\\image.bmp")) Thanks, Jeronimo Tag: Converting string to Keys enum value?

    - Can I add a FileSystemWatcher or Timer objects into application dynamically? Can I add a FileSystemWatcher or Timer objects into application dynamically? that's means i don't want to use <object runat="server" scope="application" ...... />. and i just want to use the dynamic methods just like Application["timer1"] = timerobject; to add the object into application and keep all of the events of the objects inside application can be fired up automatically in application behind-end. for example: *Global.asax <script language="C#" runat="server"> public void Application_OnStart(){ FileSystemWatcher watcher = new FileSystemWatcher(); Application.Add("watcher1", watcher); Application["watcher1"].Path = "D:\abc"; Application["watcher1"].NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite | NotifyFilters.FileName | NotifyFilters.DirectoryName | NotifyFilters.Size; Application["watcher1"].Filter = "*.*"; Application["watcher1"].Changed += new FileSystemEventHandler(OnChanged); Application["watcher1"].Created += new FileSystemEventHandler(OnChanged); Application["watcher1"].Deleted += new FileSystemEventHandler(OnChanged); Application["watcher1"].EnableRaisingEvents = true; Application["watcher1"].BeginInit(); } private static void OnChanged(object source, FileSystemEventArgs e) { /* somethings which need to be done */ } public void Application_OnEnd(){ string[] appkeys = Application.Allkeys; foreach (string appkey in appkeys) { if (appkey.StartsWith("watcher")==true) { Application[appkey].EndInit(); Application[appkey].Dispose(); } } Application.RemoveAll(); } </script> *Addwatcher.aspx <script language="C#" runat="server"> pivate void Page_Load(){ FileSystemWatcher watcher = new FileSystemWatcher(); Application.Add("watcher2", watcher); Application["watcher2"].Path = "D:\webcustomer"; Application["watcher2"].NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite | NotifyFilters.FileName | NotifyFilters.DirectoryName | NotifyFilters.Size; Application["watcher2"].Filter = "*.*"; Application["watcher2"].Changed += new FileSystemEventHandler(OnChanged); Application["watcher2"].Created += new FileSystemEventHandler(OnChanged); Application["watcher2"].Deleted += new FileSystemEventHandler(OnChanged); Application["watcher2"].EnableRaisingEvents = true; Application["watcher2"].BeginInit(); } private static void OnChanged(object source, FileSystemEventArgs e) { /* somethings which need to be done */ } </script> *Delwatcher.aspx <script language="C#" runat="server"> pivate void Page_Load(){ Application["watcher1"].EndInit(); Application["watcher1"].Dispose(); Application.Remove("watcher1"); } </script> Can i do like this? and will it be work?

    - Resource Sharing I have noticed that successive calls to ResourceManager.GetObject with the same paramters return references to different objects. This is fine when a resource is only being used once (at a time) or when an application intends to edit the returned object at runtime (and each resource consumer needs it's own copy to edit). Unfortunatly, this is a major problem when you need to share resources. For example, I would like to use embedded resources for textures of objects in my C# based 3D engine. If several objects use the same geometry, textures or other resource, they should all share a reference to the same resource object. Is there functionality in the .NET framework for shared resources? If not, is my only option to code my own SharedResourceManager class? Thanks, Brandon Bloom Tag: Converting string to Keys enum value? Tag: 82023

Hello!
I'm using XML serialization to store key assignments and came across a
little problem. Is it possible to convert a string, eg. "PageUp" to
equivalent System.Windows.Forms.Keys enumeration value?

Here is one option (in VB .NET):

[Enum].Parse(GetType(System.Windows.Forms.Keys), "PageUp", False)

If the string doesn't exist in the enumeration, an exception will be raised.
