I am using the following code to copy a file:System.IO.File.Copy(strOldFile, strNewFile)
But the trouble is that the newly-created file inherits the old file's timestamp. Is there a way to force the timestamp to update?
When I click on the Save button in the interface it executes the SaveData() steps. But I am being told that I need to update the date stamp on the Access file. How I would make this change?

I have written an application for a customer, and the application is run in various locations around the world. The company carefully controls the release of the software to the various buildings where it is being used, and because of this, I have made use of the "Check for updates" feature. The problem I am faced with, is that the folks using this software more often than not answers "NO" when prompted to download and install the latest version of the application. This is unacceptable and ultimately, we'll need to go in and have them manually install the software.
We don't publish updates to the software w/o meaning for them to be necessary, and I find it hard to believe that Microsoft doesn't recognize this sort of thing as being needed when they designed the update procedures. Alas, this seems to be the case.
I am trying to connect ftp from my vb application code is
Quote:
Try
Dim ftpReq As FtpWebRequest = WebRequest.Create("*****")
ftpReq.Method = WebRequestMethods.Ftp.ListDirectoryDetails
ftpReq.Credentials = New NetworkCredential("***", "****")
[Code]...
My first issue is that ListDirectoryDetails appears to list the modified date/time instead of the create date/time. My second issue is that the date/time field appears to be limited in size to the point it lists the year or time but not both. I can live without the year but I must have time.
Is there anything I can do to guarantee I always get the time and ensure it is returning the create/date time instead of the modified date/time? If not, is there another way to get this information?
Examples:
-r--w--r-- 1 root public 1602 Mar 11 13:31 file1.txt
-r--r--w-- 1 root public 2514276 Nov 05 2008 file2.txt
Is it possible to use the strategy to force an application to update completely every s often to prevent piracy.I mean somenone manage to crack our click once application and make some modification.but inside the application there is some part of the code that make mandatory to update it.in each update all the application is replaced completely in this way the application on the user computer is a clean one and not the cracked one so the checks for seraching for serials numbers are reinstaed is it possibile to use this as technique to prevent piracy?
View 2 RepliesI have to load a data-file (articledata.txt) which is then being used into different other excels which filter out the needed data. After X hours the data-file will be updated, so now I'd like to inform the user that newer data is available (so they can refresh the excels).
I would think I can use the time-stamp of the file when I load it, save it, and then compare it (every X time?) with the time-stamp of the data-file to see whether it has been updated, but I have no idea how to get the timestamp out of the file.
for it but couldn't find a solution. If you can link me a thread that answers this question, that'll work for me.
View 2 RepliesI need to force a DataGridView cell to update the underlying DataTable.I fill a DataTable using my adapters Fill method, then set that DataTable as my DataGridView's datasource. Lets say one of my DataGridView columns is a CheckBox column.If I left-click a checkbox in the first row and then left click a different row in the DataGridView the underlying DataTable_RowChanged event fires, which tells me the first edit I did has gone to the underlying DataTable.If I left-click the checkbox in a row and then right-click the column header to display my context menu the DataTable_ RowChanged event doesn't fire because the DataGridView row is still in edit mode.I've tried Me.DataGridView.EndEdit(),but that doesn't cause my RowChanged event to fire,I need to ensure my underlying DataTable matches the data in the DataGridView, because I am getting a subset of my original table.[code]
View 5 RepliesI have a DataGridView bound to a DataView. The DGV is setup for FullRowSelect and is ReadOnly. The first column contains a CheckBox to show that the Row is ready for processing. The user double-clicks on the row and the box is checked in the CellDoubleClick event. This works great.
I have a RadioButton on the page to hide any checked items. This allows the user to only have to look at the work that needs to be done. I use a filter on the DataView to make this happen. At the end of the CellDoubleClick, I call my ApplyFilter method, but the current row still shows up.
I got around this once before by writing some code to see if I needed to move forward or backward a row and also compared if there were any rows available, etc.
It seems to me that this relates to the value not being persisted back to the DataSet until the CurrentRow is changed in the DGV. Is there a way to force this data back into the DataSet without having to programatically change the value directly in the DataSet?
I have a combobox where the SelectedValue on the combo is bound to a property on a business object.Everything works fine, but the property that's bound to the SelectedValue on the combo only gets updated when the focus leaves the control. I understand that the property doesn't get updated until the control is validated (loses focus), but I need it to update the datasource as soon as the dropdown is closed.I know I could probably leave focus from the control on the DropDownClosed event but I'd prefer something a little less kludgy.What's the best way to immediately update my datasource when the dropdown is closed?
View 2 RepliesI have a label inside an update panel which I wouldl ike to use as a status bar.Basically the user clicks a button which executes a main fucntion that performs a series of tasks. I'd like to inform the user as to the state of the function as it progresses e.g.:
Stage 1: Retrieving data...
Stage 2: Calculating values...
Stage 3: Printing values...
Stage 4: Done!
I've tried updating the updatepanel directly from the function but it only updates the panel at the end of function (stage 4) and shows "Done!" (which I understand is how it should work).I've been looking into timers and threads to try and update the panel separate to the main function?
I am running a test program for VB.NET, and it will simply crunch a million numbers in for loop. I've linked a variable implying the progress of the for loop with the progress bar, but it seems that when I run the program, the progress bar does not update itself. The bar itself has only value 0-100 as input (as stated in the document) and I've tested it without using the for loop, and it works.

So I'm sending text with the program launchy this .vbs (addln.vbs) - ("$$" c:ideas.txt) is what the argument is if I want to send to ideas.txt for example All I want to do is make it so I get the date and time right before whatever text I send to this text file.

View 3 RepliesI'm with a big problem here. I have a 1.0.0 application that installs an Access Database into the user's machine. I have also a 1.0.1 version that needs to be released, and it has an new database file that i want to be installed overwriting the old file. Unfortunately, if the user does any update to the old file, the 1.0.1 version does not overwrite it anymore, and i did not find in any place how to force this file to be deleted or overwrited after being updated.

How to ensure that quotes are present while saving the file programatically?
I'm getting the timestamp value of an ftp file like this:
ftpRequest.Method = System.Net.WebRequestMethods.Ftp.GetDateTimestamp
Through:
ftpResponse.StatusDescription
It returns:
213 20120512102159
I'm pretty sure 213 is the ftp status code, and then 20120512102159 would be 2012, 05(may), 12(12th), then probably HH MM SS... But this doesn't match my local system, so possibly the FTP server's local time?
Anyhow... This value is a string, am I missing some obvious value of just the date? Otherwise, how do I get this string as a datetime value?
In .Net/VB.Net, what is the best way to embed a timestamp (simple text like "2011/Jan/13 13:44") into a bitmap image?
I am loading images from a database, and they come without a timestamp embedded directly in the bitmap. What I am trying to do is add a timestamp to the image when I save it.
I am currently developing a webpage, and I want to add date&time to my database whenever there is an entry on the database.

I need to begin working with milliseconds in .Net 3.0. The data will be returned from an Oracle Database and if I understand correctly Oracle can only store dates that use milliseconds as a TimeStamp. It does appears that the Date type in .Net can handle milliseconds but when I have tried to retrieve Timestamps from Oracle stored procedures in the past I ran into a nasty error. Can .Net handle the Oracle timestamp data type or do I need to bring it back as a VarChar and cast it to a date type?

View 5 RepliesMy boss wants a time stamp on items as they are entered, so far I can pull the current DateTime from the system. Problem is when it does this it has a # at either end for instance:
Dim dtNow As System.DateTime = System.DateTime.Now
When I put a break on this dtNow is #7/13/2009 10:48:46 PM#
Our back end is SQL and I have added a column of TimeStarted and I want this data to be input here, issue is SQL does not like the # symbols, how do i Trim these things off so that it will take the DateTime. I put the code in the form load event
Dim dtNow As System.DateTime = System.DateTime.Now
GetDataTable("Update AuditProducts Set TimeStart = '" & dtnow & "' where ID = '" & txtID.ToString & "'")
txtID is a hidden textbox used to pull the ID of the specific item that was just created. I went directly to the SQL server and placed this query without the # on the date time and it went in no probs.
