VS 2008 - Read Only File Creation Time
Jun 22, 2011
I have a ERP system which create a PDF file and write it to the disk when the invoice is beeing created. On the other side a have an .NET app, which every 10 minutes read data in that folder and automatically send an e-mail to my customer with the invoice attached.The problem is that sometimes, when .NET app try to read a file which currently is beeing created -> The file is damaged. How to avoid such a situation? Is there a way to e.g. read only file creation time, and if it's "younger" than 5 seconds order app to wait a while?

Just getting started in VB.NET. I would like to add X-number of text boxes at run time. And then be able to address them by their index or some sequential numerical value (like an array)
This is what I have so far:
CODE:
When I turn this into a loop to create multiple toolboxes, how do I assign a name to the controls, or will all of them be named "MyTextBox" ? I'll increment their position so thats no problem.

I'm trying to search for a file in VB. If it exists I'd like to read it in. If it doesn't not exist I'd like to create it. I'm working in Visual Studio 2008. I was using a Streamreader before, but when I did that I was never getting any sort of error if the file wasn't there, which isn't what I want.

Using VB6 to create a file and then open the file just created fails when run on a Vista client with Windows 2008 Server. The same code will work when run directly on the Windows 2008 Server or when using an XP client. If a Sleep 10000 is placed after the close, the program will work. What is the problem here? The code is as follows:
Option Explicit
Private Declare Function GetTempFileName Lib "kernel32" Alias "GetTempFileNameA" _
(ByVal lpszPath As String, ByVal lpPrefixString As String, ByVal wUnique As Long, _

In sales form, i need to create CONTROLS during RUN-TIME...
i.e, when we gone for shopping to a DEPARTMENT store, we buy LOT things... they will give us only one BILL... when they are entering BILL, they will enter only CODE of the product, all the other particulars will be loaded automatically... if v buy 10 items, there will be 10 items in BILL... if it s 15, 15 in bill...
i need to create like this only...
i.e in SALES form, CODE, CATEGORY, BRAND, S.P, DATE, QUANTITY, TOTAL etc., are available... when i click a BUTTON say NEXT, the controls specified(CODE, CATEGORY, BRAND, S.P, DATE, QUANTITY, TOTAL) has to be created automatically, in same size,and in same COLUMN (in form)(i.e CODE is a COMBO BOX, WHEN I PRESS NEXT another COMBO BOX has to be created in same COLUMN), whenever i press the NEXT...
and also, when i press SAVE BUTTON, ALL THE DETAILS HAVE TO BE STORED IN DATABASE...
I know the concept of CONTROL ARRAY... but i don't know how to implement in vb.net...

This is what I've written so far.
Using sr As New IO.StreamReader(File.OpenRead("c:\test.txt"))
Dim sb As New StringBuilder
sb.Append(sr.Read)
TextBox1.Text = sb.ToString
End Using
I've tried a bunch of intellisense options, but I can't seem to read by bits. For this example, I'm just using a .txt file, but would like to read ANY file type.

I am totally embarrassed at having to ask this question, but I'm having trouble with file IO.I want to write a line to a text file. On another form, I want to read the contents of the text file one line at a time, so I can make comparisons of it's contents.

Reading a .txt file in VB.net. My file path is C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt.
This is my line of Dim LoanOptionsFile As String = "C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt"
I can read the file when I run the program, but how do I write the file path so that someone else can download my program and file and read the file on their system?

I have found many pages referring to having the date be part of a txt file being created, but not like the way I need. Having said that, this is what I've got.. [code] I read a page on working with txt files and learned what I could from it. It said to use the method in the beginning of my code for creating the file. It works great, but I would like to have a new file name everday, hence the date being integrated. So even if program was running, when midnight hits, a new txt file is created and new entries are written to that file. But I can't even get the date to be put in there. Everytime I try to make this work by using methods I read about in other pages, I get a syntax error, or a warning saying an end of statement is expected. I'm not sure those methods are compatible with what I've already got going.I was actually trying to store these values in a database, and I got real close I think, but I couldn't get any help to fix my problem so I'm trying to write to daily txt files instead. url....

I'm trying to make my application append to a simple log file when it executed and when it's closed. So far, so good (see code)
However, what I would like to do, is have future lines of text to be written on the next line instead of the same line. And possibly a date stamp.
I'm not quite sure how to implement this as far as syntax goes.
My.Computer.FileSystem.WriteAllText("C:log.txt", "Application was closed ", True)

I created a background thread that constantly scans a specified folder for any .xls files that are created or modified. These files come from a vba macro in outlook that will automatically save the attachments of the mails in the this folder. This will update the modified date/time, or at least it seems to.
For Each fi In aryFi
fidate = System.IO.File.GetLastWriteTime(path & fi.ToString)
fidate1 = System.IO.File.GetCreationTime(path & fi.ToString)
[code]....
Everytime I check to the code, the fidate and fidate1 variables are indeed the correct dates/times of the file it's currently checking. It almost never gets inside the elseif block at runtime though.

I have been using GreaseMonkey for Firefox for about a year now and I find it wonderful, but I am really prefer using VB over JS and I would like to do some stuff that is on my computer along, not on the internet.I wrote some script for GM that read the contents of an iframe, and GM allows you to "include" which addresses the script runs on. This is really nice because it keeps the script from running where you don't want it to, AND it allows cross-domain support for communication between dom elements (in a round-about way).
I want to get away from using GM because I like some of the stuff I have already done in VB over the last 10 years and dont want to rewrite it all. So really I want to go back to my old stuff and learn how to get this functionality from VS2008.What I am specifically looking for is HOW in the world does GM listen for the creation on the window objects and run some script on it when it is finished?
Lets say I have a few webbrowser objects or other non-active xml, html or dom objects in my project. I want to retrieve info with one, send info with another, and display info with the actual webbrowser object.It sounds weird and I bet it could be used maliciously, but I mean no harm. Like I said, Ive been doing it for a year in GM already. I know .net really tries to prevent this kind of stuff cross-domain, but I figure if GM can do it, anybody can. The question is just how.
I understand how to access dom elements and all that, and I have some skill listening for events. I am just a little lost on how to combine the two in this situation. Grabbing an iframe is simple, and I realize I cant (shouldnt be able to) read it when I am acting in the parent object's domain. How do I sequester the iframe window away from its parent object once its loaded, or at the point before it loads its content so I can read it or more specifically add an event listener so I know when its finished loading? This seems super simple, my brain must just be addled.
I want to listen for the creation of the iframe from the project level, and I want to be informed of the document load from project level. I dont want to listen or do anything from the parent window object, so I really want the iframe sequestered as much as possible. Assume all iframes I will be dealing with are not of the same domain as the parent object.

I want to make a new RichTextBox contorl when a new tab page is created. I also need that control to be the child of the tab page. I created a class for the tab control. And a class for the RichTextBox control. I dont know how to start this. I have made a class for the RTB because I figured I could override the sub new procedure but you can't so i just declared it as public and set what I needed it to do. But it doesn't work.
