View 10 RepliesI am developing an application that will run with a GUI when no commandline args are passed, but can also run invisibly if started from the commandline and passed necessary arguments. I have been asked to include a /version argument that will return a version number. For simplicity this version number can be stored in a variable. Without doing something like writing the version number out to a file, what is the best way for me to return this info to the caller? My app will almost always be started from a script, so the script will have to read the version number and make decisons based on the version.

And is it possible to make ClickOnce and a msi in one solution of VS 2008? If so, is there any conflict or pitfall?
BTW I am using VB if that makes any difference.
I have made my application to start automaticly when windows start (registry ../currentversion/run/appname + path). In this mode the application start minimized and an little icon appear in the notification icon area. With this icon you can maximize the app or exit it.If you exit the app and start it again using the Menu (Start/programs etc) than the application start in minimized mode (and in this case I would like to have it in normal mode) because the setting autostart is still true.Is there a way you can detect when the application start when windows startup using the above registry or when people click on an icon in the programs menu (or desktop)?

View 3 RepliesI'm trying to add functionality to my application that will disable buttons and checkboxes depending on what version the OS is when the app is launched. I made a test app to test this but unfortunately I can not get it to work. Here is my code:

I have created a license system for my application with MySql about half a year ago. What it would do is take the serial number and send it to my server if the key was correct it would return a 0 if its wrong the return value would be a 1.The problem was that when the serial number was entered correctly my program would create a "fake file" for example vb.dll in the system.And on run time my program would check for that vb.dll if the file exist it would skip my trial program and run the app as a full version. Half year later i think creating a "fake file" and checking for it on start up is extremely wrong and that's not very good security.How can i check the difference between a full version and unregistered version?

I just want it to compare assembly version to the file version something like this (btw i also want it if it is the same i want it to enable a button):
Private Sub StartSplash_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
If Assembly Version = File Version Then

so how do i detect Assembly & File version numbers?
I would like my program to overwrite its previous version such that users don't have to uninstall the previous version before installing the new one.
I'm guessing it has something to do with setting Publish Version (Major, Minor, Build, Revision), Assembly Version or File Version.
they need to make some compare version between host version and client version.. and each 1 version different will download the file to the client..[URL]..with both example, how can i make a program in VB.NET just like i said just now?

View 6 RepliesI'm looking for a book that is pretty much A-Z for LINQ programming from Visual Basic. I am particularly interested in LINQ to SQL. I've found "Programming Microsoft LINQ in Microsoft .NET Framework 4" and while its description sounds interesting, there is no discussion on the book at all . Do any of you have any experience with this book? If so, what do you think of it?
View 3 RepliesI have been working on a project for some time now and I am stuck. I am trying to sense when a navigation software speaks so i can mute the volume of everything else on the computer.
my problem is that i cant properly sense the audio of the software. i am using windows 7 and vb.net. i have done a good amount of research, but i have not come up with an answer.
i am almost positive that i need to intercept the win32api call of the software to trigger the mute that i will use. i dont know how to do this, all the information i can find that is even close to this subject is for 98, nt and 2k.
does anyone know of any books (or websites) that contain information on this subject?
I just wonder that somone can give me propositions for some good books to learn VB.net / VB2008.. I know the basics.. So I think of not a book like for dummies.. Just something more a step forward for new things to learn.

View 1 RepliesWhat I'm Not looking for:Now, just to be clear, i'm not looking for VB6 to C#.Net content, as i know there are a few of those out there.Also, I know about that "syntaxconversion table" website, where it compares VB.Net to C# language features in a side by side table. I am not interested in this either, already know about it.I'm also not looking for a converter, which converts C# code to VB.Net and visa versa, i know there are a few websites which do this and already have the addresses.Finally, I'm not looking for a C# book or resource that caters to current programmers, but specifically to VB.Net programmers!
What I Am looking for:To learn C# (VS2008 or preferably VS2010 version) given that i already know VB.Net 10.0 (VS2010)... as there are many things related to .NET that i won't have to learn again if i can find something that will leap me from vb.net to c#, many bits of the CLR, how .NET works etc... since the languages are the same in what they do, and what they use to do them, i don't want to have to re-learn all this again. The only difference is really the syntax, but also how the C# language differs in dealing with certain things, what default expectations/behaviours are in various scenarios etc...
The set of differences and similarities between C# and VB.Net are so unique that neither of these languages likely could share this unique set/combination of differences and similarities with any other language. So my point is, it really needs to be C# for VB Developers oriented, otherwise it'll almost cetainly be inappropriate or a re-hashing!

View 3 RepliesI need to develop an application that can search through a book and list out all the pages and lines that contain a given keyword. For books that are split up in some other way, such as a bible which is split up by chapter and verse; they would be able to search for all verses that contain a certain keyword. Or alternatively, search within certain chapters and verses for a keyword. What format should I store the book into? Should it be stored into a SQL database? What format would be easiest for searching as opposed to easiest for storage?
