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.
View 5 RepliesI'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?

View 1 RepliesI 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?
View 14 RepliesI 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.

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?

View 5 RepliesI'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.
i am making a software =D (Does the Name matter ??)
Ohk so its gonna be my first try
my last soft was a success with 800+ downloads

I have antyped dataset and simlpy want to update a record by using dataadapter but the aupdate method affect only ONE Item
Here is the code :
Dim cb3 As New OleDb.OleDbCommandBuilder(da3)
DSBANQUE.Tables("BANQUES").Rows(INC2).Item(0) = BANQREB.Text
[CODE]...
It updates only item no(0) and give me the massage of the RECORD UPDATED but it dosnt it returns the same value for the other items (1,2,3,4,5)
Before performing an update, the application must search for that record in the database. Once it's found then it return to the Data access layer. Typicaly when i return rows i return them in a dataset. The i send it to the client to load on to the ListView Constrol or to textbooxes. therefore data was sent from the dataset object, therefore onces the user has made updates to the data, first i must update the dataset.
In the Data access layer i can write method that contains the command object for update DB and bind it with the current Dataset so that each time dataset updates it sychrinizes DB with it. Assume i have a method called update() in teh business layer that calls the updateDB in the DataAccess Layer, how can i call the Update() of the business layer each time the user updates the dataset?

I'm trying to update a row via c# winform application. The update query generated from the application is formatted correctly. I tested it in the sql server environment, it worked well. When i run it from the application i get 0 rows updated.Here is the snippet that generates the update statement using reflection - don't try to figure it out. Carry on reading after the code portion:
public void Update(int cusID)
{
SqlCommand objSqlCommand = new SqlCommand();
Customer cust = new Customer();
[code]....
The above final update statement works on the sql environment, but when running via the application, the execute non query runs ok and gets 0 rows updated!

View 3 RepliesIs there any way to check from .NET if windows update is enabled?
I want to prompt the users every time they log into my app that their computer might be at risk and give them a link to windows update website (or windows update application from control panel).
Preferably it should work on XP, Vista and Windows 7. Maybe there is a registry key or even better an API?
Supposedly I create a file called "hi.txt" and I use Process.Start(filename) to open it. then I File.Opentext(filename), edit it and close it using stream writer/reader, while I still have that file open.
In order to see the changed text I need to close "hi.txt" and reopen it.
Is there a way to automatically do that? Been experimenting a bit but with no luck.
Is there a way to check if a site had a page update or a new post easily?? Even just to check if something had changed on the page.
