Hi all,
I have created a small application that I need to put on a website for download. I want the application to run for free for 30 days after which time the user must contact us if they want to continue to use it. I don't want to have to deal with managing serial numbers for all machines that use the application. What is the best way to do this? Is it easy to code or is there a good third party tool that someone could recommend?
Thanks for any help.
Linda

I'm not sure how to do it with your approach but i did it by returning a table with a SQL UDF.
I don't think this approach is too friendly on the overhead, wont advise doing it with large amounts of data.
CREATE FUNCTION udfReturnMyData(<br />
@MyArg1 varchar(30),<br />
@MyArg2 int)<br />
<br />
RETURNS @v TABLE (Column1 int, Column2 int, Column3 Varchar(10))<br />
AS<br />
BEGIN<br />
<br />
insert into @v (column1, column2, column3)<br />
(SELECT Column1, Column2, Column3 From MyTable Where MyCondition = True)<br />
<br />
return<br />
END
I call this function from VB by doing a simple SELECT * FROM udfReturnMyData(MyArg1, MyArg2)
Hope it helps.
you can't forget something you never knew...

Use the Printer object to draw what you want on the printer.
For the excel file, the only way I can tell you is to add an Excel OLE to your form and open a file in that, then print the whole form using PrintForm. Ofcourse this only prints the visible parts of the sheet on the form....

Does anyone know if it is possible to search directories from the last folder created to the first in a given directory? I am using:
myFolder = Dir(MyPath, FileAttribute.Directory)
and this always starts the search in alphabetical order but I really need to search the last folder created so as not to go through every folder as the files being looked for are most likely in the most recent folders (there are many folders so it's a bit slow this way).
I am using vb.net, is there a better way for folder searches?
Hope this makes sense!

This is one of another ways. you can get subfolders of your main folder
You need a list box here,
For Each foundDirectory As String In My.Computer.FileSystem.GetDirectories("E:\", FileIO.SearchOption.SearchTopLevelOnly, "*")<br />
ListBox1.Items.Add(foundDirectory)<br />
Next
You can get directory’s creation date and time to an array like this
Imports System.IO<br />
.<br />
.<br />
.<br />
<br />
Dim folderCreatedDates(ListBox1.Items.Count) As Date<br />
<br />
For i = 0 To (ListBox1.Items.Count - 1)<br />
folderCreatedDates(i) = Directory.GetCreationTime(ListBox1.Items(i))<br />
Next i
And use for loop statements and Array.Sort(FolderCreatedDates) to sort them according to created date

Thanks Chatura
I thought of doing exactely what you have explained here although I wouldn't
be using a listbox. Thought there might have been a simple way for the dir function to start the search in reverse order, not to be I think.
Thankyou for your input.

Can't tell you much without seeing the relevant parts of the code. You description doesn't shed any light on what your code looks like, what it's doing, are what the problem might be.
Copy and Paste your code into a post, DO NOT retype it!

If what you are trying to modify is the integer cat_id, you must pass it by reference to any code that is expected to modify it. value types are passed by value by default, and so can't be modified, only read.
If this doesn't help, then do as the previous answer said, and post the relevant parts of your code. Declarations aren't enough.
We need to graduate from the ridiculous notion that greed is some kind of elixir for capitalism - it's the downfall of capitalism. Self-interest, maybe, but self-interest run amok does not serve anyone. The core value of conscious capitalism is enlightened self-interest.

You can make a COM dll, or a .NET dll, depending on who you want to open it.

I have created a Windows application and used the setup wizard for deployment purposes. It runs perfectly well on my machine but after I install the application on another machine and try to start it I get an error that says;
"Application has generated an exception that could not be handled.
Process ID 0x450 (1104), Thread ID 0x3a8(936)."
What have I messed up.

Is the .net framework installed on the host machine?

Yes it is. This is MS access database project with crystal reports. I think it may be a CR problem as this problem did not occur until I integrated the CR into the project.
