Program To Create A '.txt' File And Then Fill In Dates
Oct 25, 2009
I have been searching on the internet but couldn't find anything that would help me. I want my program to be able to create a '.txt' file when it is run for the first time, with the date and time the program was accessed, and to be able to add new 'logs' of program history every time it is accessed. What i mean is that i want my program to be able to create a '.txt' file, and then fill in the dates and times when the program is opened.

I was able to get some code working to create a dummy file to fill the remaining space of a flash drive. However, I have added a progress bar and can't figure out why it's not working. I declare a variable for the current value, min, & max properities of the progressbar and then increment it by 1 during each step of my FOR loop. However, I never see anything on the progress bar.
Dim CurVal As Integer
Dim RandomNumber As Byte
'Create the dummyfile to take up the remaining space on the drive

I am trying to create a textbox that only allows dates in like mm/dd/yyyy format. So if a user types in a date like 2010/11/02, an error would happen. But if they type it in this format 01/02/2010, then it works fine. Is this possible?

In VB6, my program simply compile to a nice simple .exe file.
However, with vb.net there are things like whatever.vshost.exe, for example.
Then there is AxInterop.MSWinsockLib.dll and so on. Should I upload that into the directory of my customer?

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.

How would one go about associating a file type with his application? I know how to read the command line arguments but I am not sure how I can "register" the file extension with Windows. Furthermore, my application is a stand-alone executable, so how would I keep Windows up-to-date on the location of my program?
I did a fair amount of searching and all I could find were old articles that didn't explain everything. How can I create file associations to a stand-alone executable in VB.NET?

I'm trying to create a "File Not Found" error to display if a file the program is looking for is not created.Example:
Dim ProcessProperties As New ProcessStartInfo
ProcessProperties.FileName = "filename"
ProcessProperties.WindowStyle = ProcessWindowStyle.Hidden[code].....
I also need help creating a text box, that will submit information to another source (like echoing to a command prompt window). I'm trying to add a killtask option where the user can enter the name of the tast (such as notepad.exe) and press 'Submit'. The button will then send a code (killtask -f notepad.exe) to a command prompt window.
