VS2008 Interuptable Socket Conversation
Nov 24, 2009
I have a server written in VB6 using the Winsock component.I need to connect to it (.NET) and be able to monitor the progress of the connection so I allow my user to terminate the connection if required or if the server is down..I've been playing with the .NET.SOCKETS classes and can set up a conversation with my server but I stumped on how I can interrupt the connection if required. Here's a senario.Connection is established with my server and transmission of data begins. During the transmission, the user decides to interrupt the process

I wrote a Socket Client which will send the Socket Server some data and get some response from Server. This process will be running once in every 2 seconds.
Now what I need to know is How we can identify the connection lost between Server and Client?
I need this to be implemented in the Client side. If there is no connection then Client should automatically close the connection. Once the connection with the server is available in the next attempt it should connect automatically.

I have road runner (time warner) as my telephone service. I'm pretty sure you can't just go making free calls through the internet via custom software or every half-intelligent programmer would be making free phone calls.I would like to know if there is a way to make an outgoing call (on the same telephone line that your handset uses) and have a vocal conversation with someone on the computers microphone/(headphones/speakers) devices.

This is a mix of C# and VB.Net. I have a C# class with with 2 delegates:
public delegate string GetSettingDelegate(string key);
public event GetSettingDelegate GetSettingEvent;
public delegate void SetSettingDelegate(string key, string value);
public event SetSettingDelegate SetSettingEvent;
In a VB class I add handlers to the event:
AddHandler _gisCtrl.SetSettingEvent, AddressOf SetSetting
AddHandler _gisCtrl.GetSettingEvent, AddressOf GetSetting
When I try and remove the handlers:
RemoveHandler _gisCtrl.SetSettingEvent, AddressOf SetSetting
RemoveHandler _gisCtrl.GetSettingEvent, AddressOf GetSetting
SetSetting is OK but GetSetting throws a warning:
The AddressOf expression has no effect in this context because the method arguments to AddressOf requires a relaxed conversation to the delagate type of the event.
Here are the methods
[Code] .....
How to fix this and why it is thrown in the first place? The 2 delegates/events/methods look similar enough that I don't know why one is OK and one throws a warning.

working with dates has always been a tricky part so let me show you how I handle dates in my application and please could you show how do you handle dates and also feel free to criticise. Normally I would create out a system to be able to save and then load a date note I am using a varchar(50) on my SQL Server db rather than datetime but I understand this is wrong, that's why I am looking for a decent way to work the dates out. My system has worked for me fine so far but if I would have to sort the dates ascending or descending I think I would get into trouble because it is saved as text.

I have a question that I hope someone here can answer.I was attempting to assign a string to a string variable and I accidently put a + in front of the string.
Dim s as String = +�Hello World I got the following compile error: "Conversion from string "" to type 'Double' is not valid."
My question is why did the + cast the string to a double.

I have a program written in VB.Net (Visual Studio 2008) that uses a DLL written in Visual C++ by another developer. I'd like to be able to step in to the C++ code as my code makes calls to methods in the DLL. Since the DLL is it's own solution, I don't think it can be included in my solution/project. I tried putting the DLLs pdb file in the debug/bin directory with the rest of my build and pdb files. However, when I get to the point in stepping through my code, and it gets to the dll call, it just steps right over the dll code. Do I have to manually load symbols?

I had a support reply saying I needed to have VS2008 SP1 update installed. I clicked the About menu item for VS2008 and it shows SP1 under Microsoft .NET Framework Version 3.5 SP1. But on the left side for Visual Studio 2008 there is no SP1. Is the framework what they are referring to?

On my last machine I had created a way to see a GUID variable while debugging by hovering over it. I don't remember what it was (a visualizer?). I have a new 64 bit machine with vs2008 - is there anyway to mouseover a guid value and have it appear? What makes guid's so special that their value doesn't show like most variables?

I am programming in both Matlab (Matlab2011a) and Visual Basic (VS2008).I've created a .exe file from my matlab code. It works well when I click on it with my mouse. But I need to run it within Visual Basic. I know it's possible to call .exe files with Shell() or Process.Start(), and it works well for files such as firefox.exe or notepad.exe.
However, it doesn't work when I call my own .exe file ... It's weird because when I look to the Task Manager while trying to call it (within VB), I can see the process starting and ending, but its output doesn't appear.

I've created a dll in VS2010 with.NET Framework version 4.0 Now I want to add this dll as a reference in a 3.5 project in VS2008. When I do this I get <The System cannot find the reference specified>... does someone has a solution for this issue. When I downgrade the dll to version 3.5 I can add it as a reference and all works ok, but downgrading to 3.5 isn't an option because other dll's are depending on the 4.0 framework.

I have a project that I am testing with Windows 7, its almost complete but doesnt function without elevating the users permissions, I've tried a few of the sample codes I've found online and they don't seem to work... This has been tested on a admin account, but still requires elevated privaliges... I believe becuase it directly effects critical and non-critical windows services (starting, stopping, retreiving the status, enabling or disabling them)

I understand the UAC could be used to implement this "admin only" restriction, but as I havent even tried using the UAC Settings area yet. As I said, a link to helpful content would be cool, an example would be great.Running Visual Studio 2005 under a Visual Basic Environment.

In the VB6 interface, when you went to Project>References, it would list all the references that have already been added to the project with a ticked box next to the name. However in VS2008, when you go to Project>Add references, the tickboxes are not there. So how do you know whether or not a reference has already been added?
