    - .NET Frame work 1.1 install problem Hello, I have a new Dell E-310 with XP-home media edition. One of the first things I did when I put it on-line was get the latest Windows critical updates. One of those was for .NET 1.1. This failed to install. After poking around the MS knowledgebase, I found some instructions which told me to uninstall 1.1, and reinstall it. I followed the instructions, but now when I try to install 1.1 again using dotnetfx.exe, I get a pop-up that says "Microsoft .NET Framework Setup cannot write to the setup log". I have over 102 GB of free disk space, I tried disabling my firewall and antivirus (after disconnecting from the net), but I always get this same message. Using Add/Remove programs, I see that there is no .NET installed. I've run RegScrubXP to clean the registry. Nothing seems to get me past this cryptic message. I appreciate all advice. Thanks, -- Tim Tag: how to set listview's backgound image? Tag: 115054

    - store, compare and retrieve encrypted strings from sql 2005 server Hi, i encrypt a list of strings with RSACryptoServiceProvider. I follow up this line 1. byte[] bytes = Text.Encoding.UTF8.getBytes(plaintext_string) 2. byte[] encr_bytes = rsa.encrypt(bytes) 3. string encr_string = Text.Encoding.UTF8.getString(encr_bytes) The last string (encr_string) i store with ado.net in a sql 2005 server database. So far, so fine.. Now i have a input string from my application, with i encrypt with the same RSACryptoServiceProvider with the same public key. And than i like to look in the database, if this encrypted string is there, so i know than, that this input was in the plaintext list without knowing the unencrypted list of strings. But when i make a simple SQL-Request mostly, i became no results... Any ideas??? Thx Nils Tag: how to set listview's backgound image? Tag: 115052

    - Using VS2005 to create web on server with Framework V1.1 I have Visual Studio 2005. I bought a domain and web hosting service (on a shared server) from a nationally known web hosting provider. Much to my surprise, they don't have Framework V2.0 installed and won't for some time. (I didn't even think to ask!) I'd be glad to use VS2003, but I don't have it. I use VS2005 on my laptop to author the application directly on the provider's server. (I am not testing it locally and then copying it to the server.) QUESTION: Can I use VS2005 (provided I only use the older V1.1 components) to start building my application on the provider's server that only has Framework 1.1? If yes, what do I need to do? As a last resort I will change web providers, but I'm hoping this is a easy config set up to allow me to use the V1.1 Framework with VS2005. (I'm a bit loyal to this provider because they host other ASP classic webs that I have. I'm not in the mood to learn about a new provider's control panels, support infrastructure, culture, etc.) Thank you, Todd Tag: how to set listview's backgound image? Tag: 115048

    - Identifying the source of a Pool Paged Bytes Leak Hi there. Our .net framework 1.1 application is a complex media player that plays back video, flash, web, TV and pictures full screen. It runs on Windows XP SP2. It has 12 DLLs and runs to about 30,000 lines of code. We're 100% .net except for two activeX controls. These are 1) Internet Explorer (ActiveX) 2) Flash Control (ActiveX) We have identified a leak in the app which will cause the system to eventually fail. This is not a Private Bytes leak but a Pool Paged Bytes leak. Our Private Bytes profile is flat. See here: http://59.167.253.24/images/pb.gif but our Pool Paged Bytes has the classic leak profile: http://59.167.253.24/images/ppb.gif Does anyone have any tips on what to look for when dealing with a Pool Paged Bytes leak as opposed to a private bytes leak? Are there characteristics that typify a Pool Paged Bytes leak? To me this looks like unmanaged code problem. Do you agree? Is it possible for something .net native to cause a leak in the Pool Paged Bytes? Any help here to narrow down our search will be a big help. Thanks for your time :) Tag: how to set listview's backgound image? Tag: 115042

    - web reference in a .net class library I have a web service that exposes database contents as disconnected datasets. I would to use that web service from within a class library. I have included a web reference to the service in my class library project. If I bring up the reference in the object browser, I see the web service namespace nested within the class library namespace, and I see the web service type definition with all of the service methods correctly described. If I look at the app.config file for the reference, I see the URL for the service in the properties settings for the class library. When I try to instantiate a service proxy in the class library code, however, the service namespace and proxy object type are not recognized by Intellisense or by the compiler. Or, actually, sometimes they are and sometimes they are not, and I can't make out any rhyme or reason to when they are and aren't. Note that I would like this class library to be a reusable component, so I do not want to have to wait until it's included in an application to be able to code to the service proxy type. What am I missing? Thanks - Russell Lane Principal SW Engineer Eliza Corporation Tag: how to set listview's backgound image? Tag: 115040

    - Determining Source of Drag Operation (Control or App) My question is fairly straight forward. I'm using .NET framework 1.5. I want to do the following: (1) Select a portion of an HTML document in an IE browser (either internally hosted or an external app) (2) When I drag that selection (possibly including images) onto my WinForm (assume a hosted browser control) I want to be able to determine the URL from the drag source. This implies being able to determine which browser instance it came from and then drilling down to the current document URL. (3) I would also like to be able to do the same sort of thing if the drag source is an MS office document. The question is can I determine the source of a drag operation? By source, I mean any one of the following - external app (like a browser or ms word doc), a hosted app (like ms word being hosted within my winform), or a specific control within my app? Thanks for any help, Tag: how to set listview's backgound image? Tag: 115035

    - Assemblies resigned/recompiled when referenced assembly patched A question from my client concerning assembly signing conventions: In order to get our main code to run inside of .NET Enterprise Services, we need to give it (and all other assemblies referenced by our main code) a strong name key. We know how to do this by running SN -K and then setting the AssemblyKeyFile attribute in the AssemblyInfo.cs file. A question comes when and if we need to make a patch release. Our main assembly references a utility assembly, shared by other assemblies. If we put out a patch release of our main assembly, we would update its version, but what about the key information? Would we need to give it a new public key token as well? If so, do we need to rebuild all of our assemblies against this new assembly with the new version and key? -- The Reg Man Tag: how to set listview's backgound image? Tag: 115031

    - I need an workaround for Regex limitation Hi, I noticed a strange behaviour, strange from my point of view anyway. Let's say I have the regex expression: "^\w+". When I do: Let's say s = "first second"; Regex r = new Regex( "^\w+", RegexOptions.CaseInsensitive...); Match m = r.Match(s) ; // here we have m.Succes = true; m = r.Match(s,6); //here we have m.Success = false; I would have expected that the ^ will match the beginning of the actual text queried, but that is not the case. The fact that ^ does not match this type of call, is possible to work around but it means a serious performance problem: to match the expression without ^ and to verify that the first match starts from 0, or to copy the string from the position I query which is not an option for a huge string. Has anyone got a clue how to make ^ working? Tag: how to set listview's backgound image? Tag: 115029

    - Cannot get audio resource in Compact Framework Hello, I am developing PocketPC application in .NET, I defined audio resource BeepSound using project properties. When I want to get resource using MyApp.Properties.Resources.BeepSound in C#, the byte array is returned, it has correct length, but contains only binary zeros instead of the sound. Sound is played correctly from resource editor in VS, and regardless of the Persistence property, the I can see the sound correctly included in the resulting executable. I can succesfully get BMP images this way in PPC application. I also tried to do similar thing in full Windows Application, and it works correctly, but there I am getting audio resource as UnmanagedMemoryStream instead of byte[] as in Compact Framework project. The ResXFileCodeGenerator tool generates this access method: internal static byte[] BeepSound { get { object obj = ResourceManager.GetObject("BeepSound", resourceCulture); return ((byte[])(obj)); } } , but object retrieved contains all zeroes, though length seems correct. What is wrong? Bug in ResourceManager? Or am I doing something wrong. Thank you Yato Tag: how to set listview's backgound image? Tag: 115017

    - BUG: Strongly-typed DataTable GetSchemaSerializable method Hi, I've created a strongly-typed DataSet that contains one DataTable. My intent is to return this DataTable from a WebService that will be consumed by a Windows Form. In my windows application, when I add a reference to the Web Service, the proxy code that is generated in the Reference.vb file throws the following errors: "sub 'ReadXmlSerializable' cannot be declared 'Overrides' because it does not override a sub in a base class." AND "Protected Overrides Function GetSchemaSerializable() As System.Xml.Schema.XmlSchema' cannot override 'Protected Overridable Function GetSchemaSerializable() As System.Xml.Schema.XmlSchema' because they differ by their return types." I can workaround this by removing the overrides directive from these methods, but a warning is then generated saying they should be marked with the overrides directive. I was having this problem earlier today in the Designer.vb file associated with the .xsd file of my DataSet before the WebService project was added to the solution and got rid of it by deleting everything and starting with a fresh solution and recreating my strongly-typed DataSet. I'm a bit farther along in the solution this time, so starting over again is not an option. In the meantime I can live with the warnings, but I have about 20 or 30 more strongly-typed DataSets and DataTables to create, so a fix for this would be great. Thanks.

    - ANN: Report Manager native, full managed version The port of Report Manager engine to C#, mono and dot net is in beta stage, but already working (Linux and Windows). http://reportman.sourceforge.net/doc/dotnetport.html http://reportman.sourceforge.net Basically you can design and tests your reports, using the report designer (Windows and Linux), selecting the dot net provider data connection, then you can execute your reports using the library in your applications. Export to pdf is working so it's useful for web applications, for desktop applications, preview and print is available, note that native Report Manager preview is much faster and flexible, but you can use dot net framework preview if you want. There is a group in yahoo groups (reportman) to discuss, post bugs etc... Thanks Tag: how to set listview's backgound image? Tag: 114973

    - garbage collection for hastable. Hello all, I am writing a class to cache xml and dataset objects that would be required frequently by my application. I also have a time to check the last access of the obect... If the object is not used for some time I would like to remove it from the cashe to free memmory. I am using hastable to store these objects. What I observe is that even if I remove the object from the hastable the memmory is not freed even if I wait a long time (more than 10 mins) to for the Garbage collection cycle to happen. To make sure there was an issue with the garbage collection I wrote a test application. I declared a class variable for Hashtable in one function I am filling the hastable like below for(int i = 0 ; i < 10000; i++) { HTT.Add(Guid.NewGuid().ToString(),new string('d',40000)); } In another function I am calling HTT.Clear() to delete the items during this time I am observing the memmory useage in the taskmanager. The memmory useage rises as expected in the first function call but does not come down after the second function is called. I waited enough for the GC cycle more thant 10 mins... after the HTT.Clear function call if I call CG.Colloect(); then memmory was coming down. I did not want to do that in my app. please suggest. Thanks in advance, Praveen Tag: how to set listview's backgound image? Tag: 114968

But on the moment I do a MyDataGrid.DataSource = nothing, I get this "Cross-thread operation not valid"-exception: The problem is: I'm not using delegates, backgroundworkers or whatever! Why does this happen? and what is the solution?

    - Generate .NET types from C header file? Hi all, The question of reusing C header files in C# comes up frequently and there's really no general solution. I do have a specific problem that I think can be solved and I'd like to get some feedback on. I have a C# app that communicates with an embedded C app via UDP packets. I have to ensure that both sides see the exact same data structure. I know how to do this by defining classes with attributes in C# and defining the appropriate header and compiler switches on the embedded system. I'm wondering if I can have a single source that defines the structure for both systems. Right now I can envision the following solutions: 1) Write a utility that parses the C header and generates the C# class definition. 2) Write a utility that parses some other file format (XML, etc.) and generates both the header and the C# class definition 3) Use C++/CLI to somehow generate a .NET type that gets imported into the C# app. Solutions 1) and 2) are doable but seem kind of tedious and boring. Anyone know if tools like this exist? The C headers have not been written yet and they will be quite simple. No need to parse exotic C constructs. Solution 3) seems a little more interesting but is it doable? Thanks for any comments, Andrew Queisser Tag: how to set listview's backgound image? Tag: 114920

    - 2.0: Nested configuration data Hi, I'm trying to specify multiple child collection under a ConfigurationSection.

    - resource leak issues in win xp sp2 w .net 2.0 Hi, we are running XP SP2 with .net 2.0 framework installed we also installed a .net application that we wrote and run it occasionally without problem. however at some point (even with our application not running) but quite a few other windows open our workstations seem to run out of resources. as in. we cannot open any more windows (be it explorer windows, IE windows or any program for that matter). or sometimes the window will "half" open (the window will come up but say the IE tool button will be missing). now if we close an existing window (IE, explorer window , calc and program) we can then open another program (like a 1:1) correlation. the other thing i noticed when i was in this state and i say tried to run a ping using cygwin i got win32 error 1114 user32 could not be loaded. we have seen this on 4 machines now. any ideas?

    - no touch request adds .config to url I have a "no touch" deployment app running successfully on XP. All machines use the 1.1 framework. When a url specifying an exe file is entered on an XP machine, the exe is downloaded by the framework (asp.net on the web server machine) and the exe runs on the "client" machine. The first thing it does is download an xml file. This works OK on the XP client. When the same url is entered on a WIN 2000 machine the exe is downloaded but whe it attempts to download the xml file a ConfigurationException is thrown. The client is trying to download a .config file. The .config is tacked on to the end of the url (no matter how many parameters are on the url) and the request fails. BTW, there is no config file associated with the executable. Why is WIN 2000 different than XP in this case? How can I prevent, or catch, this error? Thx Tag: how to set listview's backgound image?

    - database connection loss Hallo! I'm working with C# .NET 2.0, implementing Client/Server Applications which are connecting via Network to SQL-Server or Oracle Databases. To stay independent from the underlaying Database I use System.Data.Common.DBConnection and .DBCommand. How can I keep aware from connection losses (network not availeable, db-server not available...)? Are there any strategies to detect this broken connections, and how can I implement reconnecting to the database? The only solution I figured out, is creating a thread which frequntly performs a SELECT 1 (MSSQL) or SELECT 1 FROM DUAL (Oracle) within a try-catch block. When an exception occurs I have to send my other worker-threads to sleep, till I'm able to reopen the database connection and my Select-Statement works again. Then I have to trigger the other threads to reopen their connections and continue working (every thread gots his own DBConnection). For me this seems a little bit to complicated and insecure. It also could happen that one of the worker threads gots a timeout due locking or delayed server responstime, and will loose his Connection in fact of this exception. Such, or similar problems I can not get handled with my solution. Are there any suggestions, patterns or automathisms with ADO 2.0? with friendly regards Martin Tag: how to set listview's backgound image? Tag: 114912

    - Recreating an event source in a new event log Hi, I recreating an event message source inside a new log but the messages keeps ending up in the old log?! I have simplified my code into this tiny snippet: EventLog.CreateEventSource("mySrc", "myLog1"); EventLog eventLog = new EventLog(); eventLog.Source = "mySrc"; eventLog.WriteEntry("MyEntry1"); eventLog = null; if (EventLog.SourceExists("mySrc")) { EventLog.DeleteEventSource("mySrc"); EventLog.CreateEventSource("mySrc", "myLog2"); } eventLog = new EventLog(); eventLog.Source = "mySrc"; eventLog.WriteEntry("MyEntry2"); eventLog = null; The problem is that both "MyEntry1" and "MyEntry2" is written to "myLog1". I had expected that "MyEntry2" would end up in "myLog2"? What's wrong with this code? regards, martin Tag: how to set listview's backgound image? Tag: 114904

    - HashTable stores whole object as Key NOT the result of calling GetHashCode on the object when you do myHashTable.Add? Hi All I was testing my understanding of Hashtables and I thought that if I override GetHashCode then i could add an object to hashTable like so: Dim ht As New Hashtable ht.Add(s1, s1) ht.Add(s2, s2) ht.Add(s3, s3) Where s* are instance of a student class that overrides GetHashCode to return the StudentID (code at end of post). I shouldn't add it like: ht.Add(s1.GetHashCode(), s1) as the HashTable calls GetHashCode on the Key for me. This should then store the Hash (The ID returned from GHC) as the Key and the student as the object. However if you loop through the HashTable with: Dim de As DictionaryEntry For Each de In ht Console.WriteLine("Key = {0}, Value = {1}", de.Key, de.Value) Next It shows that the student is stored as both the Key and the Value. Does this mean that you should just add objects to the HashTable like: Dim ht As New Hashtable ht.Add(s1, Nothing) ht.Add(s2, Nothing) ht.Add(s3, Nothing) Seems to me I have misunderstood something here and thw whole point of a HashTable is to use a key to get to a value, was hoping somebody could clear this up for me. Cheers John Student Code Class Student Private _Name As String Private _ID As Integer Private _Age As Integer Public Sub New(ByVal Name As String, ByVal ID As Integer, ByVal age As Integer) _Name = Name _ID = ID _Age = age End Sub Public Overrides Function ToString() As String Return String.Format("{0} is {1} years old and is student no: {2}", _Name, _Age, _ID) End Function Public Overrides Function GetHashCode() As Integer Return _ID End Function End Class Tag: how to set listview's backgound image?

i tried to set listview's background image
(using managed C++)

first try, i maked bitmap and set back ground image like below code
but, it had no effect

LiveView * listViewJobTable
...
HBITMAP hBitmap =
LoadBitmap(g_hInstance,MAKEINTRESOURCE(IDB_BITMAPJOBLIST));
listViewJobTable->BackgroundImage = Image::FromHbitmap(hBitmap);

second try, i used win32 API ... using ListView_SetBkImage macro like below
code
but it had no effect too

HBITMAP hBitmap =
LoadBitmap(g_hInstance,MAKEINTRESOURCE(IDB_BITMAPJOBLIST));

LVBKIMAGE lVBKImage;
lVBKImage.ulFlags = LVBKIF_STYLE_NORMAL;
lVBKImage.hbm = hBitmap;
lVBKImage.pszImage= NULL;
lVBKImage.cchImageMax = 0;
lVBKImage.xOffsetPercent = 100;
lVBKImage.yOffsetPercent = 100;

ListView_SetBkImage((HWND)listViewJobTable->Handle.ToInt32(),&lVBKImage);

How Can I set ListView's Back ground Image using managed C++?
