View 8 RepliesI have a school project due in January to make a program in vb. The problem i'm encountering is making the actual login system. I only started using vb last year and that was purely console applications. So I am completely new to forms and I don't know ANYTHING...
The login system should be complex to an extent that it shouldn't just be a simple if statement. I have to make it so that users can create an account and that username and login will save somewhere where no one can access but vb can read from and to that directory.[code]...
I am trying to write vb program that creates system wide Hotkeys and runs at the background. The hotkey is to enter system date in another application.

Right click on node "File system on

I know the above steps are correct and should work because i did it in the other application (solution) and worked fine. When i did same exact steps (of course i changed the folder name to be created), the application gets deployed but when i install, i don't get the Personal Folder under Documents? I wonder why did it work with my first solution and didn't work with the current one!

View 11 RepliesI am a one man dev shop and need some outside opinions on how to approach this project.
I need to create a "post office" program that will send html emails thru the system.net.mail framework.
For each job submitted to the postoffice the app would need to read a user created html email string from the database, read a string of email addresses to send to and send out the emails based on a set processing time.
The first step would be to parse out the email addresses to find out how many emails it needs to send out and determine how many it would need to send per minute to complete the job in 20 minutes tops. I.e. if 1000 email addresses are submitted per job it would determine that it needs to send 50 emails per minute to complete the job.
The part I am stuck on is how I should queue the emails. If the app determines it needs to send 50 a minute should I only load up the first 50 on a timer event then get the next 50 queued up for the next timer tick? Or would it be better to load up all 1000 in a loop and build in some kind of wait time after it sends the first 50?

View 2 RepliesIn VB6, my program simply compile to a nice simple .exe file.

I am trying to create a file association in my program, which requires me to create some keys in the registry. However, when I try to create the keys, I get a System.UnauthorizedAccessException.
I have tried searching for a solution, and the only thing I can find is various examples of passing a boolean value to request write access for the "OpenSubKey" method. My problem currently is not opening the key, it's creating it. I have tried several of the different overloads to no avail.
I am guessing that I will need to temporarily elevate the access of my app to create the registry key. What I don't want to do is permanently raise the access of my app just to accomodate this one, small function, which should only really be needed by the user one time in order to create the file association.
Here is my code in progress:
Private Sub chkSOPAssociation_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles chkSOPAssociation.Click
If chkSOPAssociation.Checked = True Then
[Code]....
I have a checkbox on my form. When the user clicks it, it sets the file association if the checkbox is checked, or else it deletes the association if the checkbox is unchecked.
I want to create a program in vb .net that let me know who is using a specific file? Because I often update an .exe file but if it's in use I can't overwrite it. So if I know who is using the .exe I can call him to tell him o close the app.
