View 1 RepliesI have looked through couple of threads about making the trial application to be expired within certain time. Most of the advice is to set a timer and store it in somewhere in the system with encrytion. Then later decrypt and compare with the date installed in the system.
View 12 RepliesHere are my questions concerning VB 2010 Express:
1. I've registered my VB 2010 Express, will it still expire?
2. Will the applications I made using VB 2010 Express expire after some time?
3. Is it OK to write my code in the designer.vb file? I don't know why, but when I started writing my application it took me to the designer.vb instead of form1.vb code.
4. I've been working on an application for a week now, but suddenly I can no longer access my Design View(Shift-F7). All my codes are written on the [form name].Designer.vb. I can still view my codes but I cant access my form layout. On the solution explorer, my forms no longer have the 'form icon'. When i press Shift-F7 nothing happens. Right-clicking the form on the solution explorer doesn't show 'View Designer' option. How can I fix this?
I have VB Express and I need to make my sofware expire on a certain date. I do not want it like a trial period, I want every edition of the software to expire at the same time (15/02/12). I also do not want the software to be tricked if the system clock is put back so it needs to store the date the software is first launched and calculate the diference so it knows the true date. When the software has expired I need a message box to open, with a yes and no button. If the user clicks the yes button an IE window opens to my channel on youtube and if they click no the program exits. I have tried everything but I can't work it out.

How can I make my application request elevation privileges on startup? Basically I want the UAC prompt to appear on startup, rather than while the application is running. Currently I have a separate updater application which is launched from the main application, and it requires a UAC prompt to start. Instead, I'd like it to ask before the main application has started - a more streamlined process.

View 5 RepliesI know how to add an exit button with a prompt. However, I do not have the slightest cluse as to how I can add this same functionality to the window so that if the user clicks the X in the upper right corner, there is a prompt message confirming the user needs to exit.I added a form closing event but getting wrong results, the form closes if I click no and message window does not leave when I click yes to stay.
Code:
Private Sub frmTest_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
If (MessageBox.Show("Are you sure you want to exit?", "Close Form", _
MessageBoxButtons.YesNo, MessageBoxIcon.Question) = _

View 4 RepliesI have this problem where is wont let me create and files through the command prompt via echo xxx> C:xxx in Visual Basic. If I do it sepoaratly and run the command prompt as admin (This is not using vb at all) then it will work. I have tried putting my vb app to require previlidges at both levels at different times, not at once, and I still got the same thing.So is there a way I can use the comman prompt through vb, but also making the command prompt being an admin without turning off UAC?The code that will not work is this.
Shell(Environ$("Comspec") & " /c """ & WDir & "ToolsMediaInfoMediaInfo.exe"" --output=xml """ & WDir & "ToolsMediaInfoMediaInfo.xml""")
Command prompt's path wasnt default. How can we change that path. In mine it writes "c:usersusername>".

I'm studying creating webpages in VB.Net. After a successful Logon, I want that page to expire or simple disallow users to 'go back' to that page (not necessarily disable the back button). I have created webpages under the Master Page.

I am trying to insert a row in a table using simple INSERT Query in a transaction. It works fine in SQL Server but I am not able to insert the data using my business object.I am calling a SELECT query using the Command as:
Using cm As New SqlCommand
With cm
.Connection = tr.Connection
.Transaction = tr

I am getting the Timeout period expired error at ".ExecuteNonQuery()" line.Any other DML query is running perfectly fine at this point.
I have a Login.aspx page where if the user has the 'Remember Me' checked then it stores their username in a cookie for a year so whenever they hit the login page (session timed out, or they clicked logout at some point) the username is pre-filled. The pre-filling is working fine, in fact it works every time. The flip side is if they login and the 'Remember Me' isn't checked, then that cookie (whether it exists or not) needs to go away. The going away part never happens, even though I'm expiring the cookie. here's the cookie name, at the top of the form:
[Code]....
Well for who is willing to give this ago, all you need is 1 webbrowser and 1 button. Set the webbrowser to navigate to [URL] and the button goes the code to expire the cookie JSESSIONID which is generated by the website.
Ok the problem is that i can not delete the cookie before it expires so the only way is to set the cookie to expire e.g. webbrowser1.document.cookie.expire -1d Expires can only be used if you dim something as cookie i think.
Things i tried:
Dim cookie = WebBrowser1.Document.Cookie
If Not cookie = "" Then
cookie.Split(";")
[Code]....
This script is the only thing that works but i know nothing about this language but it does work it expires the cookie and the page lets me get another email address BUT it takes many many tries, restarting the debugging ect... because the cookie JSESSIONID is somehow not always in the same possition so when it is not first on the list i think it doesnt work (if you are going to test this you need to wait 2 secs untill the browser realises the cookie expired if more than that then u know u need to re start debugging and try again)
This should be easy but i have no idea where to start:
Do a lop through all cookies in webbrowser.document.cookie and find "JSESSIONID" cookie, expire it by -1d and then add it back to the browser.
or do a lop where the cookie is in the computer, open expire it and reupload.

View 16 RepliesFor my job I have to manually tick up to 50 boxes on a website and then click expire to remove the records from the site. Is it possible to automate this by having a small application which on the right hand side has a browser control and on the left a button which says expire all records. When this is clicked the tool knows to tick all the records and then click on the expire button? If so what sort of control should i look at using or VB code?
I want to progress this at a later date aswell so that the tool would then be able to click on each record individually to enter the record and then click re-publish? How do I get my program to loop round and then stop when it has finished expiring all the records? Also sometimes there are more than 1 page of results, so it would need to be able to tick all results, then click on the expire button, but then be able to click on the next page button and then repeat the process so it expires the records on this page?

View 2 RepliesI am creating a VB 2010 program that lets your select the program(s) you want to install (chkbox) and hit run. Then have it launch the installer ( the file is across the server) and accept the predefined keystrokes to proceed through the installation process. Afterwards, it starts the next install. Below is the code that I have. What i cant get to function is the unit accepting the keystrokes, its almost as if it wont take focus ( even when i have used Appactivate and threading.thread.sleep). I have even gone so far as to identify it as a process to manipulate the thread. To be honest, i'm at a loss and need any help at all. The final sub that contains "btntest" is where I am at currently in my attempts. [Code]
