.NET Development Socket, detect message boundaries for objects - working code?
Hi, I'm stuck with a problem that is bugging me for days. I'm custom serializing objects and sending them across async TCP sockets. However, I have a problem deserializing messages when the receive is split up in different packet sizes and I just can't figure out how to get it right. The problem is, that all works fine for a couple messages but then the header size is read incorrectly (I'm sending a header for each messages that tells the length of the incoming message so I can detect the message boundary): 2005-11-21 16:13:12.0468|INFO|Test.Server.ClientCommunicator.Server|Received connection from: 127.0.0.1:1990 2005-11-21 16:13:12.109 ...Show All
Visual C++ Problem with x64 hello world app...
Hi all, I've been trying to port a 32bit app to 64bit these past days, and finally got the thing to compile and link after a long struggle. needless to say, the thing refuses to run on my x64 XP machine, it's missing a number of libraries (assemblies, or whatever the term en vogue these days may be. God, does anybody remember the days when code was just code Sigh.) Anyhow.... I thus am now trying to create the simplest of all apps, a hello world app built to the x64 target. Same thing happens though. Now interestingly I ran 64bit dependency walker, and on my (big) application it finds that MSJAVA.DLL is missing (what a load of bollocks. ...Show All
Windows Forms Inherited forms
I'm working in C# and have a bunch of similar forms that let users do updates to a DataSet with a master-detail type of interaction. Since they have the same basic elements (save button, cancel button, load DataSet funtion, etc), I thought these should all go into a base class and then have each individual form visually inheit the base form ...Show All
Visual C# Exception Assistant not showing
I'm running some code that I know should be throwing an unhandled exception. However, the Exception Assistant never shows up, and the application keeps running normally as if I chose to continue running in the Exception Assistant. I tried resetting the settings to default in Tools -> Import and Export settings, but no dice. Any ideas on how to get the Exception Assistant back (Trying to debug code when you don't know an exception is being thrown is awful.) Exception Assistant is not shown if you are running the project/solution in Release mode. Right click on your solution, choose Configuration Manager and ...Show All
Visual C++ How do I create a folder for my library files?
I have a DLL project and I want to create a folder to contain my library files. In Visual Studio 6, all of our projects have a "Library Files" folder that contain our .lib files. When using Visual Studio 2005, I right click on the project and try to add a folder called "Library Files" and all it does is create a physical folder in the project directory and I cannot associate .lib files with it. How can I create a folder to hold my lib files Thanks. After you create this physical lib directory, you can just add it to the properties of your project as described at http://msdn.microsoft.com/library/default.asp url=/ ...Show All

Windows Forms Basic form question
It's simple question but I don't know which is the best method: Actually it's for compact framework but it's a general form problem: Just consider small forms FORM1: previous form, status hidden FORM2: actual form, status showed What I want to know is the best/ most OO way to pass information from FORM2 to FORM1 that will be showed again AND automatically start a method on FORM1 form1 :hidden form2: showed : execute query and fill listbox if user select value from listbox: pass selected value to form1 form1.show(); form2.close() start function in form1 { make query with result from listbox to ...Show All
Windows Forms Getting user inactivity time in a process
Suppose a process notepad.exe has started. I like to know how to detect a period of inactivity of a user for that process, for instance how long the user has not entered anything into notepad.Maybe System.Diagnostics can solve this problem but i did not find much information on the websites.Hope to gather some advice here. Thanks a lot G_Zola, Have you found a solution to your issue I'm don't believe the current APIs in System.Diagnostics will be able to help. It sounds as though you are interested in UI interaction - from the user - and not simply repainting, notepad idle processing, or OS interaction wit ...Show All
.NET Development System.Net.Mail messages caught in spam filter (encoding problem?)
I use System.Net.Mail for sending mail, but I got some problems. I use encoding ISO-8859-15. I send the message using html and plain text. The html portion is forced to use base64 encoding - and I cannot find how I change this to quoted-printable. And the header got bad MIME encoding. My real problem is that I am caught in spam filters like this: 3.1 BAD_ENC_HEADER Message has bad MIME encoding in the header 1.9 MIME_BASE64_TEXT RAW: Message text disguised using base64 encoding The BAD_ENC_HEADER is probably because the header is encoded using utf8 and it happens when the title is above a certain length. And I am really not tryi ...Show All
Windows Forms How to Create An OnError Event

Visual C# DirectX 9 and Windows Vista
Hello I have some experience with C# but this is my first attempt to program with DirectX. I got a problem to start off. My machine setting is Windows Vista Beta and C# express edition. When I look for add reference, I can't find DirectX under .NET or anywhere else really. So I was wondering is it because I'm using Vista or do I have to install something before I can add reference to Direct X Thanks for your time. ...Show All

Smart Device Development WM5 on ipaq: Widcomm vs MS BT stack
Greetings, I'm developing a BT application with VC++, but it turns out that the ipaq hx2795 that's my target is using the Widcomm stack, not the MS stack. I found this out when the MS SDK BT sample code didn't run so good. :^) 1) Can I replace the Widcomm stack with the MS stack Where do I get the stack 2) I know I can write code using virtual com ports, but my app needs to initiate and close down the connections. My understanding is that I need to do this with the BT Manager, and this control is not available to me programmatically. Is that true 3) Is there a way I can write WinAPI code to interface to the Widcomm stack, so that ...Show All
