Implement A Update Checker?
Apr 7, 2011
As an update rolls out in one of my applications, I would like to implement an update checker. My situation is that, when a user clicks a drop down item called "Check for Updates", I want it to check for updates. My application is simple, I don't publish. I upload to a mediafire and put the download link to my blog. The only file I need in my application has always been the .exe file of the application itself. My question is, what is the simplest and best way to implement a update checker?
Example:User is using v1.1 and checks for updates. He clicks the "check for updates" and a popup shows up with yes, update available and is a msgbox yes or no. Yes, would allow the user to download the update. No, closes the msgbox. If there is no update available, then a msgbox shows "You have the current version". If the user is offline or cannot check I would like to have an exception to show why he cannot check.Basically, working with the download aspect and everything else is familiar to me but I have no idea how I can check.
Try
My.Computer.Network.DownloadFile("downloadurl", "downloadlocation.fileextension")
Catch ex As Exception
MsgBox(ex.Message)
End Try

I am declaring an IList:
Dim OrigVendors as IList
OrigVendors = new List( of IVendors)
I populate the OrigVendors variable and what I want to do is find all the objects that have the ID I am looking for. Then I need to update a property on that object for only the ones found. Is this do able with an IList or do I need to use some other type of collection? I am using VB.net.

I am a newbie to VB.Net. Before, I did programming in PHP. I made a spell checker in PHP which splitted a big string into single word by spaces, checked if the word is there in the dictionary, if not, it highlighted it and gave some suggestions when a user clicks on it. I want to make the same thing in VB.Net.

I am using vb.net 2010, trying to generate simple classes with properties using T4 from database. Sometimes I get an error that some string is not a valid property name because it is a vb keyword. For example based on database data, my T4 tried to create a class with a property called "property". Is there a function that check whether a string is a keyword, like:[code]

I need to create a a palindrome checker program. Now I know how to check a simple palindrome by using the reverse method however I am unsure if the palindrome had special characters or spaces. My question is what is the code for removing spaces and special characters from a string using loops and if statements. Also we cannot use arrays.

I am writing a Product key checker for Windows vista and 7, well it works well in both of these operating systems, but the only problem I encounter here is that, I cannot check vista keys when I run this program in 7..and vice versa. I declared the file as seen below.
Declare Auto Function PidGenX Lib "pidgenx.dll" (ByVal one As String, ByVal two As String, ByVal three As String, ByVal four As Integer, ByVal five As IntPtr, ByVal six As IntPtr, ByVal seven As IntPtr) As Integer
The thing I want to know is that how do you declare files, in the same directory as the exe file i.e. the app directory. I wish to have the 'pidgenx.dll' files of both operating systems in folders corresponding to their OS ie vista's pidgenx.dll in folder called Pack\Vista\pidgenx.dll and for 7's as \pack\7\pidgenx.dll

I'm a newbie to VB and such, I'm currently working on a program that allows users to play the National Lottery. The program generates random numbers for a lucky dip, allows users to log in etc. The problem I'm having is the feature that allows users to input their own results and check them against the 'current results' (just a randomised list of numbers) and work out what prizes if any the user is entitled to.Now obviously there are many different combinations of which numbers are the same.Is there any way (short of writing an IF statement catering for each combination possible) I could check these results? Perhaps with the use of a loop? I don't know I'm very new to this.

I was wondering if anyone has code available that would check for spelling using VB Forms? I work in an environment that has Office 2007 installed. I'm currently using some code that works, but leaves a bunch of WINWORD.EXE process open (one for each field I'm spell checking).

I should I do so that when a program is run, it automatically checks for conditions. If true, it will continue opening the form but if false, it opens another. What I've done is it goes directly to one form and if false it will close the form using me.hide() and loads a form using Form1.show(). Problem is, if the condition is false, both forms will open. What is the right way to do this?

I am having problems getting this program to run. It is a palindrome checker, you are suposed to enter a word or a phrase and determine weather it is a palindrome. The code is suposed to contain a Boolean valued function, and should display true or false if word(s) are palindrome.
Here is my code
Private Sub btnAnswer_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnevaluate.Click
Dim Input As String
If IsPalindrome(Input) Then
txtAnswer.Text = "True"

i'am having trouble in making a spell checker for vb.net richtextbox control.I have made a form with richtextbox control and a panel control. I have put a listbox control in the panel control and filled with certain words. What iam able to do is whenever i select a word and click a button the panel appears just below the word (using get position from char) and display the choice. What iam not able to do is:
1) Select each word one-by-one whenever i click a button say F1 - I know keypress event but how do i select the words through keypress. I know they are separated by spaces but iam not familiar as to how to take advantage of it. The major problem being that there can be 2-3 words together sometimes colored as red. Eg: What i want is when i press F1 first time "this" is selected, next time "is" is selected and next time "nice car color" is selected. The two things are spaces and red color but i don't get anything from it.
2) Display the panel correctly within the main form's border. Right now when i select the last word of the sentence some part of panel disappears as it hides behind the main form. Eg - only 1/4th appears and rest hides. I can't find a way to limit it from moving when it has reached the main form size. I want to constrain it between top-bottom and left-right border of main form.

I have the following bit of code to validate two text box entries, and it catches both text boxes individually just fine but my question is: Where would I put the code if the text box entries are both valid?
Dim intExponent, intBase As Integer
Dim ErrNum As Int16 = 1
If Not Integer.TryParse(txtExponentInput.Text, intExponent) _
[CODE]...
I tried a "Case 1" but apparently that doesn't work for some reason...
