TCP Data Arrival Function - No Server Response The Program Starts To Crash And Doesn't Work
Dec 11, 2009
Im using TCP cliente to connect and receive data from my server. To read received data im using this code:
[Code]...
It works fine when server response is detected but when there is no connection or there is no server respone the program starts to crash and doesn't work, so i have to break the debuggind process.

Whenever I have an error, the program doesn't crash. It just stop executing code. The error message goes to the debug window (which I can't see until I end the program). If I have a button for example I can still click this and execute the code inside it.
I never thought I'd be asking this, but how do I make my programs crash again?
Background: My application is used to execute tests using Selenium RC servers, and occasionally I'm running into a problem when my call to a Selenium command doesn't return the response from the RC server - it then ends up blocking the thread that is executing the test.
i have been trying to make a program that should restart my server if it crashes. Just some few problems... it won't work.[code]....My problem is that when it notices the program runs, it won't do the process again, and just stop watching for the server crash.
I'm using some functions which can be compared to encoding/decoding, but it's a really simple and basic application, not really an encoding function.The problem is, the decoding function doesn't seem to work. For some reason, it doesn't work correctly, and I'm a bit stressed, so even after searching for a while, I can't seem to find it.[code]
On my software , i have a function for search in the list a member . The function have more fields : Girls , Boy , Old , etc ... but the software doesn't work correctly. I want him to search with several conditions, adding AND. Here is the code :
Vb For Each MemberALister As MemberInfo In _Listemember If Me.Girl.Checked Then If MemberALister.Nom.Contains(Me.Genre.Text) Then
I've written a program that writes and sends spreadsheet attachments to our customers. Because our customers are outside the domain of the Ex. Server when it gets to the smtp.Send(oMsg) statement (see below)the program crashes.I can use a gmail account without incident but that's less than perfect.

I am really confused! My program doesn't work if I don't have Visual Studio here in my PC. To test it I have uninstalled Visual Studio. But my program doesn't work though Flash Player is present there (I have used Flash animation in the first form).
To be more sure about it I have installed Flash. But it's not working! That means the Flash animation file (.swf) is not making a problem! It needs support from Visual Studio to start. Doesn't it mean that some files are not attached with a setup file as a result it needs Visual Studio to run? Let me tell you how I create a setup file of my program.

When I click on the icon of my program it shows the error message

i have a jQuery AJAX webmethod in ASP.Net that works perfectly fine when tested locally. but when uploaded to the server, sometimes it works sometimes it doesnt. when i debugged the code with firebug i see the the webmethod gets called but jumps right away to the error section of the ajax script.
jQuery code:
<script type="text/javascript"> $(document).ready(function () { //get current date
I have a small program which is a tcp client. I send a string from this client to a device over ethernet (it acts as the tcp server). As soon as the device recieves the input string it will respond back with response data. My problem is i am not getting the entire response data back from the server. (device).
Dim serverStream As NetworkStream = clientSocket2.GetStream() Dim outStream As Byte() = System.Text.Encoding.ASCII.GetBytes("my-cmd") serverStream.Write(outStream, 0, outStream.Length)
i have 2 exe of my program and one of them works extactly and the other one not..the reason could be that i use 3.5 versione of framework and the other pc hasn't that version??
I am using a vb 2005 and mySql as my database. I already created my project but it seems like when i edit my program.. it doesnt apply. What might be the problem? Is the vb.net application, MySql or the OS?
I'm trying to execute a program on a remote machine using this code
Dim objProcess As New System.Diagnostics.Process objProcess.StartInfo.FileName = "cmd.exe" objProcess.StartInfo.Arguments = " /c PSExec /accepteula \NTAPPMTMIGL01 -u $AdminUsrLocal -p tjdsi44 c:winntMicrosoft.NETFrameworkv2.0.50727gacutil.exe"

If I use it, it works since I'm an admin but if someone else use it, I got "The system cannot find the file specified."Is there any other program I can use that can impersonate, I've already tried xcmd.exe but it doesm't work either.
i am working with simple UDP based client server application . The problem i am facing is that theoretically the MTU size of ethernet is 1500 bytes , but when is send more than 1400 bytes of data then the the dataarrival event which is supposed to be called two times is called only once, Now this is confusing as the there should be two time the event be raised
The default installation of my setup project is as follows:
[ProgramFilesFolder][Manufacturer][ProductName]
The problem is PC in Europe don't have a "Program Files" folder, it's in a different language.When I remove [ProgramFilesFolder] from the setup program, the installation doesn't work. I would like to install the application in C:AppFolder,
I have one tool which we developed on visual studio 2010. there are basically two parts of my project, one is UI part which i wrote in VB and algorithm part which is in C++ on back end. When we compile C++ part it creates a .dll which is used by my front end VB program.
Now my problem is little weird since i am compiling and deploying this tool on windows xp machine but some of the users are using windows 7 64 bit machines and after running the program for about 5-10 minutes, it crashes on windows 7 with following error
Not enough storage is available to process this command and when i view details of that error, i get the following description.
See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.
************** Exception Text ************** System.ComponentModel. ************** Loaded Assemblies ************** mscorlib
[Code].....
i am completely clue less for this error since this program works fine on xp but doesn't work on windows 7.
When you Use Socket.Send Ether in VB6 with the Winsock control or Vb.Net sockets / Windows API does it generate that if you send "Hello" that on the other side it will get the Full Message Before the Data Arrival event is triggered??Or is it possible it can get it in two Different events like "He" & "llo" and a Last question, TCP is stream oriented, is there a Protocol that is Message Oriented but is wrapped with TCP, if not what is a good Delimitor to use with TCP, Usually ide use &H1 OR &H0 but I assume &H0 is common.. or Should I just add a Length Param before each Packet I send..?Now if thats the case and I got the Delimitor route... What if Im sending Chunks of 8192 of a File in a while loop and on a different thread I send a Command if I use the Length Param isent there a huge chance that the messages will get sent like this

BUT the issue lies as it thinking that only the 3 of 4 of the incomming file Frames are getting Recv due to it not knowing which frames are for which. Mainly due to me sending a big burst and on the other side recving random chunk sizes on the other side.Edit: Got another question, If I send two bytes across the internet via TCP, will they ever arrive as two different I belive the term is Frame or is that only when they exceide the size of the MTU will the Message be Split. The reason why is if I send a Header saying SOH, Length Of Message(2Bytes), thats 3 bytes can I say 100% of the time the computer on the otherend will recv that all at once so I can parse it? And What ever happen to Flush for Winsock?
Have a program that collects response data as part of a psychology experiment and i want the output text files to show up on the users desktop so that they can find them easily and e-mail them to me. I'm using Parallels on my Mac to run windows XP and found the files in a desktop folder but they were not on the desktop. Am I coding this right?
I'm doing a baseball program for a class project. And I almost have it complete, but it's giving me a syntax error. I can't figure out what i'm doing wrong. I'm using two functions to return a value for different type of baseball tickets to the button that calculates them. Here are the instructions 1.)User selects whether to purchase season tickets or single-game tickets 2.) User enters the number of tickets needed and the type of seats based on whether they selected season single-game tickets.3.) User clicks the Compute Ticket Cost Button to display final cost4.) User clicks the Clear Form button to clear the responseI just can't figure out what I did wrong. I know it's something stupid that i'm doing.the errors are happening inside the btnCompute sub routine. with syntax erros on SingleGameCost() and SeasonalCost() line 114 and 118

i made a tcp/ip application using the .NET TcpListener class, my problem is that sometimes (about 30 / 4000) the connection between the client and the server got interrupted in the middle and the server response to the client is lost.is there a way to know if the server response was successfully sent to the client without the client response back?
I am using stored procedures in my application using vb.net, while executing stored procedures on mysql database server thru application, the response time from the server is more. Is there any settings that i need to set on mysql db server or any changes in connection string or in code.
This emailing code wont seem to work in my program. I get an exception "The SMTP server requires a secure connection or the client was not authenticated. The server response was 5.5.1 authentication required."
