How can I retrieve the value without writing it into text file. I know there's a namespace SYSTEM.XML but I'm not familiar with its classes
I mean the imports keyword on the uppermost part of the program.
View 3 RepliesOne of the convenient and simple events I liked for textboxes in VB6 and VBA was the afterupdate event where after you finished typing in your data or text, you pressed enter and the program processed the text in the textbox. In VBNet, life is not so simple. I have included a simple code to do the same thing using the keydown event and checking to see if it is the enter key. This code just send a message box with all the text in it. You can manage things from there

This is probably simple, but the answer has eluded me. How can I move a folder from one drive to another drive. System.IO's MoveTo won't let me move a folder to another volume. Any thoughts?[URL]..

View 13 RepliesI have a VBnet program that works fine and I'm hellbent on getting it to run under Linux eventually (looks like mono is the way to go sometime soon). But, for now, I'm looking at some of these code converters, online and otherwise and have some questions.
I tried a single procedure of code with the online converter and it threw quite a few errors relating to the procedure lines themselves (the opening Private sub etc, etc,)Something about C# and handles clauses -- can't remember.
So, I suppose the online converter just wants to see the code itself? As in, what lies between the Private sub blah -- CODE -- end sub?Now, what about something I saw this morning, "Sharpdevelop" that says it can convert entire PROJECTS to C#? (Also saw a 200.00 software package as well).
Is that the way to go? Will it do every bit of the project's code start to finish? You just load the project folder or the project file I guess?But then I see Sharpdevelop doesn't compile -- so you convert with it and then open the converted file with Visual studio C#.net?
I guess Microsoft will never have this conversion capability in visual studio?
In C# I can create an interface, and when I use the interface the compiler knows that certain interface requirements are fulfilled by the base class. This is probably clearer with an example:

On all my forms, or is a better route creating an abstract base class that has SetupForm() (and how do you do that in VB.net)?

Is there any way of not having to use these "proxy"-calls to the real method? I haven't found any useful information about this in the CLI-specification, which makes me suspect that this is a VB.NET "feature". Is this the case?
This is what happened: on the form load of my application i created a background worker to bind collection (records from database filled in the dataset) on my control. but the problem is when the i updated the records on the database it throws an error if i run this procedure again.
If xControl.InvokeRequired Then
Dim MyDelegate As New InitializeDataBinding_Delegate(AddressOf InitializeDataBinding)
Invoke(MyDelegate, New Object() {xControl, xQuery, xPrimaryKey}) ' ERROR HERE SAYING: Collection was modified; enumeration operation may not execute.

I would like to do a replace all using VBnet 2003 and MSword 2007.
I got to this
Dim Selection As Word.Selection
Selection.Find.ClearFormatting()
Selection.Find.Replacement.ClearFormatting()

It crashes EVERY line with the selection claiming that "Object reference not set to an instance of an object." I got the code by doing a macro recording and it worked fine as a macro but I do not want macros in my document.
I wish to communicate over usb in vb.net i realize i might need to use openfile windows api or createfile windows api but im doing a generic mouse driver which should be miles simpler to do since microsoft and usb.org already have the report descriptors available so all i want to do is just send data to the device directly using my program.

I'm working on a little app which needs to recieve information from a script on a web server. I tried to have the vb.net app pole a php web page for a command every half of a second. This worked but, the app is streaming video and every time the app needs to pole the webpage the video stutter stops. I tried setting the pole timer to 5 seconds and still every 5 seconds the video stutters. I thought that maybe sockets would be the answer, so I looked for examples of vb.net socket servers and php socket clients. I tried implementing a solution but the php cannot seem to connect to the vb.net server. I googled around and saw that maybe php cannot communicate with a vb.net application.

View 2 RepliesI have a library that interacts with our phone system, ie, Hey phone, call this number for me. This library is used in one of our in house products. I would like to put this instead in a service, so that any of our in house products can send the service a message to place a phone call. So basically I want to communicate from a program built in .Net 3.5 with a service running on the same machine also built in the 3.5 framework. I have done some work with WCF and was considering using this but thought I would ask what others have done or would do.

I'm coding a restaurant program where every table, server and guest is a different object - Is there a right way of getting objects to communicate with each other?For example, one server might have 5 table objects, each table might have 2 guest objects.

If a guest moves to a different table I have to change a large number of variables (number of guests served by server, table set to empty, new table sat...etc etc.)?

View 3 RepliesI am writing a VB.Net application wherein I would like to be able to communicate with it from a remote computer. Specifically, I would like to be able to send (from a remote computer) both text data and also images (jpg, png, etc.) and then have the application use the sent information by displaying it to the user. How would I code the VB.Net app to be able to handle incoming data like this?
If possible I'd like to not be dependent on .Net technology on the "sending" side so I'm not sure if I would just use sockets or a web service or what.
