I've spent the best part of the week learning about TCP/IP and sockets but it's really draining my enthusiasm for my project. The basics are simple enough and the MSDN examples are fine and I can put together a simple server/client easily now, but once I start getting into asynchronous connections, threading and all the other stuff, I'm getting bogged down and frustrated. I've followed a dozen tutorials and examples now and they're all too confusing and half of them simply don't work.
I think what's most frustrating is that I really don't wish to become an expert on sockets or TCP, which seems to be the advice on most forum replies. I really want to be getting on with my project which has ground to a halt since I started looking into this. Yes, I know the world isn't always that simple.
So, what I'm looking for is a 3rd party app or some working code that will let me set up a server and multiple clients. All I really want them to be able to do is to send strings to each other, without blocking the application. Really, that's it, just the ability to pass strings back and forth between server and client, preferably in as simple a format as possible - e.g SendMessage(Client,String).
I am sure this can be done, as Visual Studio is basically built this way. What I want to do is simply make a class that my other workmates can use. But rather than have it in a code form, I want to build it (partially), and then my workmate can add it into their programs (sort of, like the add reference for the .NET stuff).
I started with VB 6.0 back when i was 14, I was mostly into coding programs that interacted with other programs. Recently I installed VB.net 2005 pro i got from school, and i grabbed few source codes that teach show interaction, I feel so dumb, i dont remember anything lol. It be great if you guys can share some source codes and other stuff in this field. also other day i was in dream spark and i am able to get copy of VS.net 2010 ultimate edition, are there a lot of major changes, cause i got 2 thick book for VB.net 2005..
When you've finished a program and you're trying to distribute it to the mass public. How is the best way to go about doing this? What sites would you post your program on and getting the word out that there is a new program on the block and it does xyz. This is directed to freeware so there wouldn't be any advertising.
Sorry for not explaining it very well the first time.
I am trying to use some 3rd party web service for which i hv sample file which is writen in C# and same I am trying to rewrite in vb.net for implement till last line I hv understood and implemented , but I am not able to understand last line in this code so pls help me to understand the last line of this code how to write same line in VB.net

I am writing a small application that will display some info to my end user. I have another program that the end user will have open while running my appplication. What I am trying to do is have my application launch itself (and maintain positioning if other app location changes) and "tether" itself to the other application.Ideally the top left of my application would attach to the top right of the other application.I have tried for countless hours working with the GetWindowPos API but the values returned are either all zeros or it just doesn't work.I do a Try/Catch to see if the other app is running and I fetch the Handle of the process. This works fine. Then I try to get the positioning of this process and set my .Left property to the returned RECT's .Left property. no dice.This is Visual Basic 2005 ExpressOther application is a PuTTY window that is not a fullscreen app.
my program launches a 3rd party program with a few switches to update itself.Once these updates are complete I need to manually click save from the applications menu. This can be done via the keyboard (Alt Gr + M then Alt Gr + S)
The application will take several seconds to load at which point the application will open maximised and the save option will be enabled.
Does anyone know of a good 3rd party reference for Win32 API for .Net where VB.Net is the target language Most API references target C as the language of choice. Frankly, I hate C and all C like languages.
I'm using VB 2008 and I'm trying to add a xmlns="mynamespace" attribute to an XDocument's root element.The XML document is created by a 3rd party, and I have loaded it into a VB XDocument object. As it comes, it has no namespaces. I have been working on a local copy and I added in a namespace in a text editor, so that I can use the XMLToSchema in VB to enable intellisense etc, as per the instructions in the Beth Massi vids at MSDN. Now the rest of the code works I want to open the live documents again. Without the namespace, my XML literals don't resolve.I've tried unsuccessfully to add in the XMLNS property to the root tag using a few methods, and the nearest I got was the following three code samples.
Dim myNS As XNamespace = "urn:nbf:namespacename" myXML.Element("nameofrootelement").Add(myNS)
^^^^ The namespace was added as the value of the root element, not as an attribute.
XML.Root.Add(New XAttribute("xmlns", "name"))
^^^^ Generated the error: Run-time exception thrown : System.Xml.XmlException - The prefix '' cannot be redefined from '' to 'name' within the same start element tag.
but
XML.Root.Add(New XAttribute("test", "name"))
^^^^ works correctly. Presumably it doesn't like me manually trying to set a reserved attribute? This namespacing seems way too over complex from some of the Googling I've done.I thought to .ToString it, then modify, then .Parse it also, but I wanted a better solution so that it would help me understand it a little better! I did try this though, and as you rightly point out, it affects all the descendants too, so thus it still breaks.
I will be working with multiple XML feeds all produced by different third parties, and I think for simplicity I will be leaving out the namespacing entirely!My own custom parsing function rewrites the third party feeds into one uniformed document, which then gets processed by another routine. I'll be able to add a ns to that intermediate piece of XML which will help when coding the secondary function.
I am working with dev ex controls and on a menu bar item there isnt a property for setting the button to Visible or not Not Visible. Can you add properties like this to pre made controls? If so how would you do it?
Im trying to detect when numbers change in a 3rd party app and then capture them for crunching. I do recall something back in the days of vb5 that would list control info when the mouse hovered over it. Cant seem to find anything like it these days. Ive got window handles ok, just cant read the control data.
Working on a program that makes use of a third party API. That API can be found here:[URL]I'm a beginning/intermediate VB.Net developer, and have written other programs, but not using something like this. I suspect I'll need to create a Web.Request (Secure) object and 'POST' to the URL with a stream of XML text. That's the general idea, right? The actual URL is internal to our network and I have that information of course.
I'm still new to most of this but I seem to be finding that while you can load the Microsoft Reference Libraries at no charge, I'm told they are the slowest method to use.I have tested Gembox and only read about others. Is it worth the effort to deploy these 3rd party platforms, even if I'm working with small data sets, for the moment at least? Speed is one thing but when you're talking about 2 seconds vs 0.2 seconds, it's not worth $900 per seat.
Are there other 3rd party references which are Open Source, or no cost, etc...I would like to hear what the rest of us are doing on this?
Do i need to add a reference to a third party control(DLL) before i can use it.When i go to project->add refernece ,i select the control but it didn't becomeavailable in toolbox to use it.Do i need to install that control?I just placed it inwindows/system32 dir.
I use SelectNodes("//Party") to extract all the Party nodes. Then I have seperate processing for all the nodes that are not Party and are not children of Party (HostName, HostVersion, etc).
I'm using a third party dll for my project and one of the function that is provided by the dll use form handle as one of the argument. But when i call the function, I'm not using any window form and it's just called from another class. So what value i should put for that argument?Here's the example of that function:
After this function has been called, it will send message to the form_handle argument whether the measurement data is available and valid.I called this function from another class just for triggering start measurement and i have another function to retrieve the data. I do not have any form associate to it, what value i should put for this argument?
Some will remember my first thread about extracting an image from a 3rd party application. The solution that was offered was to use the Easy Screenshot class that is in the code bank.While this solution works, there are obvious drawbacks. I'm trying to fully automate this program, and needing the window to come to the foreground, even momentarily, defeats the purpose of it.Is there another way to get the image held in a picture box of a 3rd party application?
My goal is to control an application from VB.NET. There is no API, and I do not have the source, only the compiled EXE file. Is there a way to find the opened application, find a button within the application, click a button and know it was clicked? Is there a way to read the contents of a textbox within the application?
I'm getting closer to the point where I need to look into software protection. Ok, stop laughing, I'm looking for something easy, able to make trials, unlock via internet are my primary needs. Does anyone have any recommendations from personal use or seen any reviews comparing different softwares? I've seen about a dozen already looking around today but would like anyones feedback.
We would like to know if there are any recommended tools in .NET that can scan through a VB .NET project & do an analysis.It should report on the Lines Of Code, provide no. of Routines, No. of 3rd party Tools, No. of Variables, Forms Diagrams, No. of Classes etc.
The error message that I've been getting for the past few months when trying to access functions of a specific third-party .dll using vb.net is this: "An unhandled exception of type 'System.AccessViolationException' occurred in test.exe Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
I've been researching this error message, and I have come to know that it is likely due to either attempting to access memory that isn't available or due to "enhanced" security features.I am trying to access a third party .dll. The functions in that .dll all deal in one way or another with Handle types (either returning them or accepting them as parameters). I understand that handle's can be essentially pointers to pointers (pointing to an entry in a memory table, which is itself a pointer), and I also understand that handle's don't, strictly speaking, exist in the .NET framework, but I do understand that through some combination of IntPtr's and possibly the Marshal class, they can be dealt with.
I don't believe vb.net's lack of a Handle type is the problem, because the dll function that I am calling, which on success returns a handle, returns a number <= 0 if the ip address it is searching for is not found, and the ip I specified doesn't exist. Also, the error really only occurs when executing the code from within the the Visual Studio environment. I compiled the executable and ran it 77 times(literally), and I only got the error on the 77th try.
I'm trying to find out all I can about this error. I would like to completely eliminate it. Could the error come as a result of something happening within the dll itself? The function asks for an ip address, and the ip address I have specified doesn't currently exist on the network, but as far as I know, the function handles that by returning a number less than or equal to zero. I am very confused as to what the problem could be. I have successfully interfaced with .dll's before. I've read about the hotfix for .NET 2.0 regarding this error message,but I'm a little skeptical. I've tried everything else I can think of, though, so I may give that a shot.I'm 100% certain that:
-I am calling the correct function within the .dll
-I am using a signature that matches the signature of the function
-The error has nothing to do with User Account Control.
The code is very simple to try to isolate the issue:
Imports System.Runtime.InteropServices Module test <DllImport("3rdparty.dll", EntryPoint:="#12")>[code]......
