    - Any way to get Framework to return Line number of my code? I'm pretty new to .Net. I'm writing a Service and I have a number of debug statements that go to a log, and I was thinking - it would be wonderfully convenient if I could get the line number of my source code into the log. I have done it "manually" with statements that have the line number hard coded into them, but every time I change the source above them, those line numbers are "out of date". Not a real big problem, just something I'm curious about.

    - XML from ResourceManager? I'm using XslTransform to create an HTML page. The XSL page has all of the HTML formatting. The actual text for the page comes from resource files that are language dependent. I was using ResourceManager to load the correct resource file, but I need to pass XML to the XslTransform class. Is there a way to pull out the XML from a ResourceManager? Or is there a better way to pass the language specific resource file to the XslTransform class?

    - Using regular expressions to parse INI file Folks, I was trying to parse standard Windows INI files using regular expressions, but I can't seem to get it to work all the way.... I have two tasks, basically: * retrieve all the section names (names between [....]) * given a section, retrieve all its key=value strings I can achieve goal no. 1 by having a regular expression of "\[(?<section>(.*))\].*". This seems to work okay - I can load the INI file into a string, and apply that regex to it, and iterating over all the .Matches and looking at the Match.Groups["section"].Value entries, I get my section names: StreamReader oSR = new StreamReader(<name of my INI file>); string strINIFile = oSR.ReadToEnd(); oSR.Close(); // grab all the section names by means of a regular expression MatchCollection oMatches = Regex.Matches(strINIFile, @"\[(?<section>(.*))\].*"); foreach(Match oMatch in oMatches) { string sConfSection = oMatch.Groups["section"].Value; // do something with sConfSection } However, I can't seem to get any regular expression working that would pick out all the key=value pairs for me, from a given section. I figured I'd just search for the "[section]" token, and then grab anything up to the next "[" character - but I can't seem to get that working..... Any ideas???

    - ReflectionTypeLoadException From GetTypes() Hi all, I could really use your help here. I am trying to create an instance of a class defined in one of my assemblies, from a method in the same assembly. The problem area of code looks something like this... Assembly runningAssembly = Assembly.GetExecutingAssembly(); Type[] assemblyTypes = runningAssembly.GetTypes(); // Now I have some types, find the one I'm looking for and use Activator.CreateInstance // to return an instance... Seems pretty straightforward really, doesn't it? Well, the GetTypes() call fails with a ReflectionTypeLoadException "One or more of the types in the assembly unable to load". I've done a fair bit of searching and on several occassions have seen the 'make sure all dependent assemblies are in the same directory or GAC', which is fair enough. As far as I am aware, all of this assemblies dependencies *are* in the same directory or the GAC. Having checked ILDASM manifest information for externs, it looks okay to me. I've also checked the Fusion log and that seems to be as expected also. The top of the stack trace looks something like this... at System.Reflection.Module.GetTypesInternal(StackCrawlMark& stackMark) at System.Reflection.Assembly.GetTypes() at ... [the calling line in my code] ... Are there any other places I should be looking for dependencies? I have noticed that some of the manifest version numbers do not match the actual version (manifest version always older) but I don't really know what to do about that, even if it is relevant. Are there any other cases in which this exception would be thrown? I'm stumped right now. If anybody can shed some light on this I would be really grateful. Thanks in advance. Antony.

    - Calling managed CSharp code from a C++ dll I have a dll written in C++ running along in my exe and would like to call an API from the dll into the managed code portion of my exe, which is written in C#. I know that you can call a function in the C++ dll by using the DllImport statement and declaring a P/Invoke compatible API signature for the managed portion to call into the unmanaged portion. But can you do the reverse? Essentially, what I want to do is have the C# section provide an particular function as a callback to the C++ dll so when it is ready to perform a certain task, it makes a call to the callback function provided in the C# section (which can be made into a dll). Is this possible? If so, can anyone give me suggestions on where to start? Thanks in advance, Justin Tag: SystemEvents & PowerMode change Tag: 77870

    - This pisses me off This is what pisses me off. We have an application that is a very large commercial application. The application has several COM dlls and MFC code Occassionally we get assert on 1040 line in dbgheap.c,heap pointer (passed to free/delete is invalid).It is not reproducible, What is frustrating is that there is no help from MS to dectect such problems. We already wasted 2 months tring different approaches. PageHeap that every Microsoft Employee so proudly talks about is the peice of crap. Can you imagine allocating 1 page after every allocation. Maybe it will work for test apps that Microsofties write for their own testing but it is a piece of crap for a big application ... I am so sick of this problem. MS keeps talking about .NET LongHorn, bullshit etc but never tries to research ways to help us fixing the existing problems. I wish all developers and companies out there buycott the ,NET and all other crap Microsofties keep pushing at us. Many of you may sense frustration in my mail and I really am frustrated .

    - Xml :: Deserialize stream of specified range. Hi, I have a potentially very large xml configuration file. When the file is parsed, using an XmlTextReader, each configuration section is stored into a HashTable - not the xml content itself, but essentially (ill make this easy to understand) the start and end positions of the config section within the Stream. When it comes to deserializing the configuration section, I know exactly which part of the Stream to look. However, I have no way of specifying the range of bytes to deserialize from, using XmlSerializer.Deserialize(Stream s). I could read the range of bytes into a MemoryStream, and then deserialize from the MemoryStream, but I don't really want to have any significant part of the configuration file in memory. I'm very new to .net, have I overlooked something here? any help appreciated. Tag: SystemEvents & PowerMode change Tag: 77856

    - C# .NET server Socket class And VB Client Winsock API(Problem Recognising disconnection) Hello All, I am using C#.NET Socket Class At server And Winsock API at Visual Basic Client.Every thing is working well. I want to give facility of reconnecting to client if connection terminates due to any problem either from server connection or from client connection and resume it from its old state. The code I am using for it is as follows: TcpListener listener = new TcpListener(1001); listener.Start(); socket =listener.AcceptSocket(); Above socket object is communicating with client. To check if connection is alive i have wrote following code. noOfTry=0; while(noOfTry<5) { try { this.socket=this.getSocket(); this.socket.Send(byteData,0,noOfBytes,System.Net.Sockets.SocketFlags.None); break; } catch(SocketException ex) { noOfTry++; Thread.Sleep(2000*noOfTry); this.socket=this.getSocket(); } } Problem I am facing is that socket is not throwing SocketException if connection has broken and executes socket.send() method without any exception. However when second time this method is called it throws SocketException I am using socket.receive() method to receive data in blocking state. If client has closed itself normally, socket.receive() method at Server side detects connection broken by receiving Zero bytes. But if there is some problem in network, then socket.receive()method also fails to detects it and thread is blocked for ever in socket.receive(). Please suggest me what to do????? Any suggestion or Code will be appericiated..... Thanks n Regards, Abhishek Agarwal Tag: SystemEvents & PowerMode change Tag: 77827

On one machine (winxp, sp1) with MS Access 2000 installed, my program= can't access database. Only until I use the Access 2000 "repair" functionality to repair my database. After that, the code works fine. 2. On some machine, even after repair, still code can't access database.= 3. It seems that my code (c#) can access some tables, while can't access= others. I have only 1 db file storing all data. The symptom is my progra= m can read user information from the database file (used for log in), but after I logged in, subsequent calls to get more data failed. 4.

    - Mixed code - "not registered"? We are attempting to move a large development project into the .NET age over time. We have a large number of ATL-based COM objects in this project. Following the "Journal Poster" example provided by MS, I have converted some of my COM projects into mixed code so that there is both a .NET and COM interface to the underlying logic. So far, so good. In one of these former COM projects, four additional COM objects are within from the underlying logic as a matter of executing the main interface method. Our testing shows that this all works perfectly well through older programs that are using this project as a COM object, but when accessed as a .NET class library, only three of the four objects are loaded properly - attempting to create the dispatch for the fourth COM object causes a COM exception reporting that the object is not registered. I have traced the problem right down to the call to CoCreateInstance and I have checked the registry, but I'm at a loss as to how to proceed from here. Any ideas? Other than not being registered, what can cause a "not registered" message?

    - Key Generator based on HDD serial number Hi I want to do a key generator based on the local computer hard drive serial number. My problem is on getting the hard drive serial number. I found many examples like the one below, but this code gets the hardrive with "c:" id, so it will not work if the computer doesnt have a drive with the id of "c:". My question is, how do i know all the hardrives id on the local computer? Does anyone knows a better method to do this? (This is the code I am currently using to get the hard drive serial number) Dim disk As New ManagementObject("Win32_LogicalDisk.DeviceID=""C:""") Dim diskProperty As PropertyData For Each diskProperty In disk.Properties Console.WriteLine("{0} = {1}", diskProperty.Name, diskProperty.Value) Next diskProperty Thanks in advance Dante Tag: SystemEvents & PowerMode change Tag: 77809

    - getting ambientproperties event called by Active X using .NET framework - c# Hi. There I am trying to do what the visual c++ can do using .NET framework - c# MSDN : http://support.microsoft.com/default.aspx?kbid=183412 What I am trying to do is changing USER AGENT: string of web browser control sent to a web server. according to the MSDN, it seems it is possible using OnAmbientProperty event of CWnd of MFC so, I tried to do same on .NET framework using c# by overriding GetService method of Container class first, I created WebBrowser control on win form, and made a MyContainer class to override GetService method class MyContainer : Container { .... override ... GetService ( Type service ) { ... } } and added the webBrowser control to it. myContainer.Add( webBrowser ); according to debug information, webBrowser is properly added - myContainer and webBrowser are connected by Site. and then , I test - runned the application. during the application start up, it called GetSerive as expected - when active X control needed to get some ambient info from its container. and, when I clicked on a hiperlink of web page, the GetService method was called as expected. - okay, so it seems I am getting OnAmbientProperty event called by Active X - WebBrowser Object. but, that's it. I am stuck in this stage. I couldnt figure out how to inspect what the DISPID is. therefore I can not find out which event call is for DISPID_AMBIENT_USERAGENT. so, I can not override user agent string of what the WebBrowser control sent to web server. so, is there anyone who already did this kind of stuff? or anyone who can help me? I will really appreciate, if someone can teach me how to find out DISPID of ambientproperty event and how to override - which field I should write - user agent string. oki doki thank you sincerely HeeJae Chang Tag: SystemEvents & PowerMode change Tag: 77807

    - Serialize/Deserialize TreeView Hi, I need to serialize/deserialize a treeview in order to retain its nodes/values. the serialization worked; using soapformatter: System.Runtime.Serialization.Formatters.Soap.SoapFormatter _sf = new System.Runtime.Serialization.Formatters.Soap.SoapFormatter(); string _filePath = "tree.xml"; TreeNode _RootNode = new TreeNode(); foreach (TreeNode _tn in this.TreeView.Nodes) { _RootNode.Nodes.Add((TreeNode)_tn.Clone()); } FileStream _fs = new FileStream(_filePath, FileMode.Create, FileAccess.Write, FileShare.None); _sf.Serialize(_fs, _RootNode); _fs.Close(); but at the deserialization I get an "Specified cast is not valid" exception System.Runtime.Serialization.Formatters.Soap.SoapFormatter _sf = new System.Runtime.Serialization.Formatters.Soap.SoapFormatter(); string _filePath = "tree.xml"; _fs = new FileStream(_filePath, FileMode.Open); TreeNode _Root = null; _Root = (TreeNode) _sf.Deserialize(_fs); // here is thrown the exception _fs.Close(); this.TreeView.Nodes.Add(_Root); one more thing, the Tag property of each TreeNode contains a custom class which has 4 fields filled with information and I made it Serializable and implemented ISerializable. the TreeNode is serializable, my class is also serializable, yet the deserialization does not work :( Any ideas how to make it work?

    - easy grid editing ? ? ? (equivalent to msflexgrid) can someone explain how to simply populate a grid in .net ? the way i understand it, there is no more msflexgrid, and instead is this new control that has to be tied to a dataset, and it is a real pain to work with if you just want to throw some values in a grid and edit them with a textbox. i don't want to persist anything in a database, i just need a fast cheap and easy grid in memory that i can work with! i had functions in vb6 that would insert (tab & vbcrlf) delimited text into a grid, and vice versa. it was super easy. if you clicked on the grid, it would superimpose a textbox you could type in, and on lost focus, the textbox contents got copied into the appropriate cell. is there some existing code to do this in vb.net easily? (i stress EASILY! it's 2004, this kinda stuff is supposed to get easier as technology advances is it not!) many thanks ----- vb6 code i want to find equivalent to: 'this function converts tab/vbcrlf delim text to a msflexgrid Function fn_sCopyGridToText(ByRef grdTemp As Object, ByVal iFirstRow As Integer, ByVal iFirstCol As Integer) As String 'this function converts contents of msflexgrid to delim (eg tab/vbcrlf) text Sub subCopyTextToGrid(ByRef sString As String, ByRef grdTemp As Object, ByVal iFirstRow As Integer, ByVal iFirstCol As Integer, ByVal sRowDelim As String, ByVal sColDelim As String, ByVal bClearGrid As Boolean) 'when user clicks msflexgrid, puts a textbox over the cell they clicked on so they can edit text in cell Private Sub grdValues_Click() Dim sGridDisplay As String ' SAVE POSITION g_dictValues.Item("iGridRow") = grdValues.Row g_dictValues.Item("iGridCol") = grdValues.Col ' GET VALUE sGridDisplay = fn_No_Empty(grdValues.TextMatrix(grdValues.Row, grdValues.Col), "", True) ' get value in grid ' BUILD TEXT BOX, PLACE OVER CURRENT CELL txtEdit.Text = sGridDisplay ' copy text of current cell into edit box txtEdit.Top = grdValues.Top + grdValues.CellTop txtEdit.Left = grdValues.Left + grdValues.CellLeft txtEdit.Width = grdValues.CellWidth txtEdit.Height = grdValues.CellHeight txtEdit.Text = grdValues.Text g_dictValues.Item("sOriginalText") = grdValues.Text txtEdit.Visible = True txtEdit.SetFocus End Sub ' grdValues_Click 'when user exits textbox, save contents in grid Private Sub txtEdit_LostFocus() ' =================================================================== ' SAVE TEXT IN GRID grdValues.TextMatrix(g_dictValues.Item("iGridRow"), g_dictValues.Item("iGridCol")) = txtEdit.Text 'grdValues.TextMatrix(g_iGridRow, g_iGridCol) txtEdit.Visible = False End Sub ' txtEdit_LostFocus Tag: SystemEvents & PowerMode change Tag: 77794

(&Hashtable) I load a type throught method such as Assembly.GetType(typeName) and I put it into a hastable, as a key later on I *try* retrieve some information from this table with code like PropertyInfo pi; myhashtable[pi.PropertyInfo] unfortunately this doesnt retrieve the value ?!?!?! looking step by step in the debugger I see the following weird thing. my hashtable doesn't have tyhe proper key but a simple wrapper over the type of type System.RuntimeType any idea of what's going on ? and how to avoid it ? -- Lloyd Dupont, Software Architect Get Your Data Mobile http://www.ihookdb.com Tag: SystemEvents & PowerMode change Tag: 77792

Hi

I'm using SystemEvents to indicate to my app that the system is entering/resuming to/from standy mode. When the system resumes, I do not appear to immediately have the network available and my app fails because it is trying to make use of network connections.

Is there any way of telling that the operating system has 'resumed' (and network is available), rather than it is about to resume (via PowerModeChanged event)?

Thanks

Jon
