    - Caching Application Block I tried to use CAB in my smart client application to store cache using memory mapped file. I want to create cache in a disk resident storage type so that when application closes or the pc reboots, I can still continue working on the data by accessing the cache.

    - .net Framework 1.14322 I am receiving an error message each time I run various apps, including any Help files. . It reads: .net framework initialization error. To run this application you must first install one of the following versions of the .net framework: v1.1.4322 and v1.0.3705. I have 1.1.4 installed, there's even a folder named C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322 I even get this error while trying to install MS files I downloaded to try to solve this problem, such as NDP1.1sp1-KB867460-X86.exe. This can't be related to any one service that I downloaded, as it occurs in a number of different situations. It pops up in MSN Explorer, when trying to install MS software as noted above, and other areas. Someone please figure out why?? I'm running Win ME, by the way. MSIE 6.x.

    - Strongly Typed Collection Problem Hi All I have a class Persons that hold key/value pairs of Person class. My problem is the following. On the first screen I create an instance of Person, I then add a name and surname and then add the class to class Persons ( I can add more than one Person class on this screen). On the next screen I retrieve the Person I am interested in and add Home Address or whatever I wish to add. The problem starts when I call the Add method of the Persons class. The value (Person that's been updated) is never stored or updated in the Persons class. public object Value { get{return this.mValue;} set { if (this.mValue != value) { this.mValue = value; } } } Can some give some green light?

    - Getting an array of structures from Win32 API calls I have a small chunk of Managed C++ code that is attempting to call into an umanaged Win32 api to retrieve a list of structures. Unfortunatly, I'm not having any luck getting this code to work. Any help would be appriciated: I'm defining the pointer that will hold the array of structures as: GROUP_USERS_INFO_0* pstUsers = NULL; The actual API call looks like: status = ::NetGroupGetUsers(server, unmanagedGroupname, 0, (LPBYTE*)&pstUsers, MAX_PREFERRED_LENGTH, &dwEntries, &dwTotal, &dwResumeHandle); I'm getting sensible results back for the dwEntries and dwTotal fields. I then try to parse out the group names: StringCollection* results = new StringCollection(); for (DWORD i = 0; i < dwEntries-1; i++) { System::String *s = System::Runtime::InteropServices::Marshal::PtrToStringUni(pstUsers[i].lgrui0_name); results->Add(s); } Much to my annoyance, my string always ends up with garbage in it. I'm not to familure with Managed C++, so I'm probably doing some very obvious wrong, but I'm not making too much progress... (I can't use the DirectoryServices for this, as I'm talking to an NT4 Domain rather than AD, and this particular method isn't supported...) -- Chris Mullins Tag: Server Client Asyn. communication Tag: 83482

I am sure that I am not the only one that has had this issue. Or is it because I used a dirty N word. "Novell" Here is my previous post. I really hope someone can help with this because I don't know what else to do. Abandoning Novell is simply not an option at this point. UnauthorizedAccessException when trying to access a Novell network drive. The code is very simple. This is the line that fails when trying to create a new StreamWriter where _filename is a string that points to a Novell network drive. StreamWriter file = new StreamWriter(_filename,false); The user has full access to the directory. By the way. This line works fine on the local box as well as accessing a Windows NT 4.0 or 200x Server drive. This issue is only with Novell Drives. The client is Windows XP SP2 using the native Novell client drivers that came with XP. I have not yet Tried the Novell Client Drivers from Novell. Any help would be greatly appreciated.

    - Debugging in IIS My co-worker and I can not seem to set up our IIS environment to allow debugging if we are both working on projects. The server is win2K sp4, IIS 5, ASPNET version is 1.1, Visual Studio is 2003.

We are both members of the debuggers group, and that group has full control of our working directory. We still get errors when we are both debugging. The error is that there is another instance of the debugger running and the machine can not start another. Any advice or guidance would be greatly appreciated. Thank you.

    - Where can I find a design pattern for paging through a list? Hi, How do websites like google page through large numbers of records? For example; if I do a search on Google, get 187,000 matches, and go to the 22nd page of the results; I'm sure Google doesn't do a new SELECT statement and traverse through 440 records (22pgs x 20 per page). But I'm also pretty sure Google doesn't keep a hell of a lot of session data open either. I know there are all kinds of ways to do this, I've created hacks which did the job in the past. But there has to be a 'best practice' way of handling this. Can anybody point me in the right direction? I'm open to technology specific ways, but would prefer generic.

    - Interating over the characters in a string Hello, I have a question in regards to .Net string maniplulation. I have a question in regards to interating over individual characters in a string. The problem is I have a CSV parser that will successfully parse out quoted csv files, the only issue is it will leave the leading and ending quotes in tact. Before I go on I do realize since it's a CSV I could do stringval.replace( "\"", "" ); but I wanted to take the chance to learn out to iterate over string values. Anyway, the problem is what I had written originally to do this was: if ( stringval[0] == '"' ) { stringval = stringval.substring( 1, ( stringval.length - 1 ) ); } if( stringval[( stringval.length - 1 )] == '"' ) { stringval = stringval.substring( 0, ( stringval.length - 2 ) ); } I wasn't stripping off the last " ever and I realize now that the problem has to do with .Net storing strings in UNICODE, which allows for character pairs to reprisent a single character. So my question here is, how does one iterate over the character values in a string and replace it's value if neccessary? Carlo Tag: Server Client Asyn. communication Tag: 83411

    - Serialization of HttpWebRequest I think this was asked before, but not resolved... I'm trying to serialize a 'HttpWebRequsest' object, send the object to another maching to actually make the web request for me. Since 'WebRequest' implements ISerializable and has the SerializableAttribute, it seems this should be possible. I've tried doing this, and it seems something gets lost, because when I deserialize the object, I get a null reference exception ( I think the method verb is not set among, possibly, other things). But I don't see why this could happen since serialization serializes the whole graph of objects. Am I missing something? Thanks, -A Tag: Server Client Asyn. communication Tag: 83406

    - .NET Printing and Windows 2003 Server VisibleClippingBounds proble I have a DOTNet printing application I wrote and also a Crystal Reports printing issue on a Windows 2003 Server. The visible clipping area bounds returned is incorrect and causes the printout to be clipped to this incorrect smaller region (about 33% of the size it should be). The code below is from the onPagePrint method protected override void OnPrintPage(PrintPageEventArgs e) { // Draw a box around VisibleClipBounds Graphics gx = e.Graphics; g.DrawRectangle( Pens.Black, Rectangle.Truncate gx.VisibleClipBounds)); ..... ..... } The properties returned are incorrect on a Windows 2003 Server and correct on Windows XP. i.e The gx.VisibleClipBounds.Height is 1066.667 on Windows XP and 416.3333 on Windows 2003 Server. The printer is an HP LaserJet 5M. I have not tested any other printers as of yet. This incorrect value causes my program and Crystal Reports to have the report clipped to this bounds and thus cutoff.

    - virtual serial ports I wrote an application in C# that uses the unmanaged Win32 calls for COMM. I can communicate without problem on the standard comm ports (i.e. COM1, COM2) but am having a problem with virtual ports that are using USB->serial adapters (i.e. COM4, COM7). I can connect successfully to these ports (CreateFile), but when I execute a ReadFile(), I hang if I have the read timeouts set to infinite. Here is the interesting part. If the virtual port was previously opened by another terminal program such as Hyperterm or TeraTerm, I have no problem. If I disconnect the adapter then reconnect it to the system (Win2k) then try my program, I hang as described. If I then run one of the other terminal programs, my program will now work. It appears that there is some initialization being accomplished by the other programs that has some persistance. Once they are run, I have no issues. I'm using synchroneous communications with no flow control (it's to an embedded system on a reference board). I am not using overlapped operations. I would think that the Win32 library should be able to handle this, that the level I'm working at should completely abstract the differences between virtual and real serial ports. Obviously, this assumption is not a valid one. Has anyone run into this, and can anone offer me some advice? Thanks, Howard Keller Tag: Server Client Asyn. communication Tag: 83393

    - "Start Menu -> Run"/Shell Functionality from C# I'm trying to duplicate the functionality of "Cmd /C" from within my C# windows application. This means that I want to create a function which will accept a string containing any of the things that "Start->Run" can and will use the Windows shell's abilities to figure out what to do with a command string, including: * Executables themselves, * File names without application specified which are opened in the appropriate application for the file type. Using the Process class to do this seems almost impossible. I tried using Process and providing "cmd.exe" as the FileName and the " /C <string to run>" as the Arguments. It worked except that it left a blank black command window on the screen after launching the appropriate application. I also tried using the VisualBasic Shell() function but also seems to demand that an executable be presented. I find it hard to believe that I'm going to have to do system registry look-ups to determine what Application needs to be inserted for a given file path provided. Help? Thanks.

    - COM+ ActivityId Question I have to questions regarding running .Net components in COM+. 1) Is there anyway to tell if a .Net assembly is running in COM+ before attempting to access System.EnterpriseServices.ContextUtil to gain access to methods such as ActivityId, IsInTransaction, etc.? These functions raise a COMException if no COM+ Context is available. I'm want to check to see if a COM+ Context is available without raising an exception before accessing these static properties. 2) I have a rather simple, class that inherits from ServicedComponent that has been installed into COM+. When accesssing the ActivityID using the above mentioned ContextUtil.ActivityId property, I'm getting "00000000-0000-0000-0000-000000000000". In the documentation for this property, MSDN says: "The GUID for an activity if the current context is part of an activity; otherwise, GUID_NULL." I can't find any information about "GUID_NULL", but I'm assuming that this is what is being returned. Is there a reason that the COM+ context for my component is NOT part of an activity? I'm not a COM+ expert, so I'm not entirely familiar with the difference between contexts and activities, but I do know that when creating COM+ applications using VB6, there was always an ActivityId present. I use this value to trace activity through various COM+ calls for debugging and logging purposes. Thank you, Michael McGuire Tag: Server Client Asyn. communication Tag: 83369

    - Alternative for ActiveX I have a client who currently has an ActiveX application. They are considering replacing this application due to business reasons and have asked us to consider alternatives for developing it. Our shop is a C#, .Net shop. I have identified Hosting Windows controls and FlashMX as the closest possible current alternatives. Unfortunately, the current application has printing as a core function. To the best of my knowledge, this eliminates both of these choices (assuming default security settings). Are alternatives that I am overlooking? Is a Windows application the only other next best alternative? I'm assuming that there is no way to build an equivelant of an ActiveX in .Net; is this assumption correct?

    - Process.Start With Microsoft Word 2003 I have a RTF document that for whatever reason when I do a Process.Run("C:\MyRTF.rtf") the process starts, but the startinfo is set to nothing. Dim P as Process p = Process.Run("C:\MyRTF.rtf") In this case, P = nothing, but Word 2003 launches. I have tried to force it to use WordPad, which works fine with Process.Run. Anyone have any ideas how to force it to keep the same process with Word? Thanks. Tag: Server Client Asyn. communication Tag: 83354

    - Can't Access application config file with APPSETTINGS through fire We have a client with an ISA Server 2000 configured in cache only mode, and a checkpoint one firewall. Integrated authentication is required for requests. We can replicate the problem with an ISA Server 2000 configured in integrated mode, with integrated authentication required, and the Web Proxy used. The problem is this: We have a no-touch deployment client side .NET application configured at a URL. When navigating to this URL, the application downloads with no problem, but all access to APPSETTINGS to retrieve application settings fail - they return blank values. If we disable use of the Web Proxy on the ISA server on our replicated setup, everything works. This is not an option on the client site. The problem appears to be that the behind-the-scense XML requests used by the .NET framework to access the app.config file are sent as anonymous requests, which are blocked by the firewall. Is there a solution to this one? Any help appreciated. Tag: Server Client Asyn. communication Tag: 83342

    - Detect which Framework is installed (including language) How do I detect which language the .NET framework is installed with? I want to know this because we have an error related to .NET 1.0, which is corrected in SP3 of the framework. I want to detect if the client is running .NET 1.0 without SP and offer a download link. But if my client is running .NET 1.0 US it should be a link to the US SP3 and if the client is running .NET 1.0 Danish, then the link should point to the Danish SP. I know I could tell them to run Windows update, but I want to use our own high-speed servers. Thomas Tag: Server Client Asyn. communication Tag: 83339

I am working on a server client asyn. socket communication via TCP in pocketPC

the program is successfully compiled
and the server and the client is successfully connected
However, when the program execute the command:
Sock.Send( byteDateLine, byteDateLine.Length, 0 );
An exception is caught:
System.InvalidOperationException:InvalidOperationException
What is the problem?

The InvalidOperationException is normally thrown when you attempt an
operation on a Socket that is not yet connected. Are you doing an Async
connect? If so you may be doing the Send before the Connect has completed.
