The idea is to have a central place to put the routine in instead to copy it into every .vb file that belongs to each .apsx code file.
I'm using a central startup routine to initiate several TCP connections, start up a background thread that does some monitoring, and instantiate a group of objects that track information throughout the lifetime of a networking session.
There are periodically server-side problems with the protocol I'm working with, at which point the whole mess has to be torn down and set back up, so at the front end of the startup routine I'm disposing of instantiated tracking objects, killing the monitoring thread, and disconnect/close the existing sockets (if they're already set up). At that point the sockets may be in the middle of an asynchronous send or receive operation, which is causing system exceptions when the socket is torn down and then the asynchronous delegate gets called and EndSend or EndReceive thinks there isn't an object there anymore.
I had assumed .Disconnect and .Close would take care of these async processes, and I'm a little lost. Is there some one-shot method I can use to abort those async operations before I tear the sockets down to re-instantiate them?It never hurts to try. In a worst case scenario, you'll learn from it.
I need some help with to make a messages system. I build a form with display a message code and the message.
Example : 0000001 : Not connected to network
The problem is that i want to store in a central place where the numbers and the message will be stored in the code. I was thinking about a array to store the date.
I am working on a program using VB.Net 2010 which will enable me to setup groups of files & folders for back up with syncing capabilities etc. I have a concept program which is based on some sample code I found out in one of the VB.Net forums. I have modified it from a command line based program to a form based program. At the moment I consider this code to be a "concept" program which once I have the various copy/sync routines developed and debugged will be integrated in to another program I wrote for
creating "Back Up" groups to automate the process. There are some 3rd party programs that do similar things that I want to do such as Microsofts Sync Toy, but none of them offer the grouping and exclusions options that I am going to program in to this backup/sync program.
So here is my problem, I have the included code taking two folders, a source and a destination, and copying everything from the source to the destination. It will skip over any unchanged files/folders and will delete anything found in the destination folder that is not found in the source folder and it will update all files in the destination folder that have a newer version in the source folder. In other words it will mirror image the source to the destination but will be smart enough not to copy unchanged items from the source to the destination thereby saving a lot of time. The sync part of the program is working fine, the displaying of the progress and results is not.

is there any way to reference a particular code routine in VB.net external to the current loop/routine?Example:
If Var01 < 5
[Routine A]
Else
[Routine B]
End If
where Routine A and Routine B are code sequences at the end of the entire program -- such as outside of the current sub or class? The idea would be to reference an otherwise repetitive code.
I need to implement a routine to read a plain text file, BUT that file has a predefined format.The file format is as follows:
Quote:
<FILE_PROPERTIES> 'The "< >" also appears
Propertie1="String" 'It's possible to have spaces after or before the "="
Propertie2="String"
Propertie3="String"
PropertieN="String"

Is there any Windows API Routine to read something like that?Or could you point me an URL where something is implemented?I don't want a procedure to read the file line by line and comparing them with Line Input because blank spaces, empty lines and comments starting with " // " may appear too, and I don't want to take them into account, but also I need to save changes to the file, but only to the modified section, without having to read the whole file, and re-write it completely.
Binary access can't work, because I don't know what's the size of each "section", since the number of elements into it can change.
I need something like the "ReadINI" Windows API Procedure, but allowing me to read the "[XXX]" sections headers, and also the "<XXX>" file title header.

View 7 RepliesI have a insanely large file that has a lot of customer data in XML format. The start of a customer and end are how I'll determine the starting and ending points of the customer data I need to extract. The is the number I'll be searching for. I'll input a regular text file with 12-byte document numbers into the file (Doc Number List.txt), search the massive XML file (example.xml) for those document numbers, find the data before and after the DOC_NUM tags, but within the CUSTOMER tags and extract it to a formated file. The formated file needs to have these tags, <?xml version="1.0" encoding="ISO-8859-1"?>

I've been looking at accessing shared folders, read and write, via the network without being prompted by the OS for the username and password.
On this forum, and googling, I can find many things about accessing network shares, but none using code which also passes the username and password required.
What I'm basically looking for is to not have to map a drive on the users computer. Then using code, write or read files from a network share and at the same time pass the username / password required for that network share.

I have basic text report (.txt) that is created by a custom application. My client would like it to page break at a certain spot.
Does anyone have a routine that would allow me to insert PCL code into the file so that when printed it page breaks? I'd search for certain text and then insert the codes just prior to the text.
Certainly if someone has a better "mousetrap" then let me know.
Like I imagine everyone, I often have problems navigating my code because the flow can jump from place to place. For example, if my code calls routine1, and I then want to go to routine1's code, I know that I can click in the dropdown menu and it will take me to that sub. But wouldn't it be easier if I could somehow right click on the call to routine way and select something like 'take me there' which would transport me from the function making the call to the code for the function being called? Then it would be easy to hop from place to place.

What I Want To Happen:- When the user saves there work I want the name of the file to be shown next to the name of the program at the top left hand side of the form.

View 7 RepliesI want to write a generic file saving routine where the routine is passed data in the form of a collection and it sets a containsStructure flag. I wanted to be able to save the data from the collection, but if it is a collection of structures I want to be able to extract the data from the structure to write to the file.
The only trouble is, that I cannot do something like:
For Each s As dataStructure In data
Next
Since the compiler complains that dataStructure is not defined. Is there a way to code around this?

I am developing an Application in VB.Net 2.0. I have a module which would copy files from the Local Machine to a shared folder on remote machine. This shared folder on the remote machine is an authenticated folder. So, after searching on the Internet I found the following piece of code.[code]Another point to note is that when I connect to the File Share using Windows Explorer and then try to execute the application, it works properly.I am not sure why I am getting the error when I do not connect to the Shared Folder using Windows Explorer.Do I have to set some property so that the Credentials passed in the authentication are used.I also checked some posts that suggested setting up Mapped Drive to the Shared Folder on the Local machine and then to copy the file using IO.File.Copy function. However, I cannot use this as this Remote Folder should be only accessed through the application and not in any other case by the User. The users will not even have the credentials to this remote Server as it will be configured by the admin.So, Is there any way in which I can set this up and transfer the files from local machine to a remote shared folder?
