Read A Text File To Check For Updates?
Mar 28, 2010
I'm trying to make my app check for updates by reading a text file and comparing it to a 'currentversion' setting in my application (or if checking the executable file version is easy, that would be good).
Here are the basic steps: -Read text file hosted on [URL]..-Check if the version number (eg '1.1') is higher than the number in the 'currentversion' setting or the executable file version (whichever is easier).
-If the text file version number is the same, change form background colour to green, if it is higher, change the background colour to red.

Alright, when I open my program I want it to check for updates and if there is an update I want it to download. So far I have a text file saying the most recent version and then it downloads that file and compares it to the current file version. If the current file version < recent version then it will download the file. :O Can someone help me with the code? :3 I have a hosting server with direct download links.

I'm unsure of how realistic it is for this to work but I know a lot is possible in vb. I have an application called WindowsPRO available from my filesharewebsit This application is intended for those in school to easily be able to do several daily tasks such as calculate and use notepad within one window. I have been working on this application in part with the help of MSDN.Back OT, currently when I click the "Check for updates" I use process.start to open my website. Not very complicated is it. What I want to do is open a form in whichchecks for the update from my site. Whenever I upload a file, I'll upload it as a .zip onto my site and always name it like: "Application name v1.0" or whatever the version number is. That is the only thing that changes.
When the user presses the check for updates, I want to checkhe site in background for a "higher" version number. If my application is v1.2, I want it to check for anything higher than 1.2. So if I have on the site 1.2.2, or 1.3, I want it to check for the highest number version and download it.My question simply is, how do I check for a "higher version" from a website?

I don't like to build myprogram to a click-onceapplication becauseI lose the .exe and I don't know how to edit it after building it. So unless someone this, here is my main question:I was thinking about updating a .txt file that have uploaded somewhere that has the current available version. Can I use streamreader for an online file? And if so, if the available version is updated, how can I edit the code and everything to updatethe file?

I have a program with commercial uses. Currently I have email out updates. I would prefer that when the program loads, it searches for updates either from the web or I was toying with the idea of creating a file host server. I want the program to search for updates without opening a web browser, however (giving anyone power to email out a free download link). I think of the way Digsby opens, checking for updates, or gimp. This is what I want.

As most programers will want after spending a long time on a program is to implement program updates, so have i.
What i want is a nice simple way of doing the following check if file exists as "www.mydomain.com/program/install.exe" if true, download and launch install.exe on completion, un intstall current vertion ( if possible )

I have created a backup script which my organization uses to back up a specific set of data weekly, to a server, by clicking and running the app.I am always updating it/ improving it and instead of redistributing to the select employees there has to be a way to code in a "check for updates" type of thing.
I was wondering how to make my created app check with that server to see if i am running the latest version.
How do i incorporate a "version" in my app, or would it just be a naming convention thing? and how do i check for updates? Would a button being selected to check updates be preferable? or is there a way to auto detect it?

I've gone through about 16 hours and two packs of cigarettes trying to figure this out. First a little background. I was using 6.0 up until 2004 when I went to prison. I'm out now, and trying to relearn the trade, using VS 2005. I'm currently porting some 6.0 code from another project, SpyCast Webcam Studio, into VB 8.0. It's disheartening, to say the least. None of the old built-in subs/functions work anymore, so I have to scour the forums to relearn each and every function.The section I'm doing now takes a snapshot from the webcam (Video API --> PictureBox --> Save as Jpeg), then upens the file to upload it to the server via HTTP POST. I've been using this code in SpyCast for years with no trouble, but I spent many hours trying to piece together the right code to open the binary file to read its contents. I pieced together two methods I found around the forums, one using FileStream() though the code I found wasn't for binary files, even though it said it was, so that code doesn't really work. Method two uses Microsoft.VisualBasic.FileOpen() and works better.
Here's the kicker. By the time I run through the rest of the rigamarole of uploading the file, by the time I read it on the webserver, it's *slightly* corrupted. It's a valid Jpeg, no errors, but the picture looks like when I use to watch the Playboy Channel when I was a kid scrambled with weird colors and whatnot. [code] Each "chunk" is basically one "line" of the file. It looks like a single LineInput() return is the text between two carriage returns. Am I correct? I tested this with a flat text file, and it looks true. However, That one input line returns the text or data with the carriage returns *stripped*! ***?!? =( Fine, I have no problem adding my own vbCrLf to each LineInput(), if I were opening text. but this's binary. A character could be Chr(10) or Chr(13), both of which are removed from the original file contents.So I could very well need to use something other than LineInput(), but I haven't found any other examples on the web using this method.

I'm using vb.net 1.1 to develop the program. I got text files that contain test result from a machine, like below.
T1 1.24535 2.56335 2.43253 1.24538 2.55619 4.35243
T2 1.42542 1.63728 3.57295 4.59275 1.57320 2.72057
T3 5.12857 2.45375 6.38593 2.58375 3.57259 3.57204
I need to check the test result with the data from database, to find out which test result is failed. If there is a fail test result, I will show an alert to the operator and stop the checking process. Until the operator close the alert, then the checking process will continue from the last read point.

I am wondering if there is a simple way to make the text to speech occur after the updating of label.text
If I have the following:label.Text = "words words" voice.Speak(label.Text)
I would like the label on the form to display "words words" before it speaks. I'm a beginner with vb, and the only thing I could come up with was to use a timer. Just wondering if there's a simpler/more sophisticated solution.

how to do this for vb6 however i am using vb 2008 and the code for vb6 does not seem to work.
I have designed a form with a text box on it, and a command button underneath. The idea is to run this as a sort of stiky notes section.
I want the text box to read rich text into the textbox (C:\\stickynotes.rtf")
Then i have a command button underneath which i want to save the content of the rich text box to the rtf file (C:\\stickynotes.rtf). This is so that the user can edit and ammend information.
here is some code i have so far
Dim fileReader As System.IO.StreamReader
fileReader = My.Computer.FileSystem.OpenTextFileReader("C:\\stickynotes.rtf")
