Which Files To Use For Update
Sep 2, 2010
Have a small application (forms) that I want the clients to be able to update.I am using one location on the server to store updates, and one for the original installer zip. Could this be a problem, in that both need to be in the same place?The app is in its infant stage at the moment, but I'd like to get it to update from day one.Which files do I need to put on the server in order for the app to update. At the moment I've tried the '*.application' file, and the 'Application folder' & its contents.

i have a project that requires me to make a unit converter. the units should be defined within the program. i have reached a point where i save the defined units in a text file for a simple example converting meters to kilometers where it gets divided by 1000 i made the program to save the a string in a text file to represent that as:
meter,kilometer,0.001
which means it gets multiplied by 0.001 anyway the problem that i'm facing that when i want so save another units in the same file the previous units gets deleted. how to make the program update the text file that it adds the new defined units in the same file but before that it looks in the test file if the unit is already exists and if it does it will replace it with the new value
is it possible to read a string just before the second comer? foe example if the string in a file is: meter,kilometer,0.001 it will read it as: meter,kilometer and is it possible just to read the last value? 0.001

what methods use to update the main exe and related files in the app dir?
im using a seperate exe which runs with admin priviledge which downloads and replaces files as necessary.
my app downloads a text file and checks the version in that. if newer than settings.version then it runs the updator.exe and then closes.
the file downloaded also contains links to all new updates. the updator reads from this file then downloads as neccessary. then deletes the file and closes

I use text files to hold the program data, which is loaded in to variables when the program starts. I use StreamWriter to write to the text files when they update within the program. This is fine although the writer adds a extra line when I do not want this, which causes the program to error on the next use.

I have two, soon to be many spreadsheet files. There are cell references between the files which need to be updated. I would write this in a excel macro but these spreadsheets are design tables for Solidworks, a CAD system and it does not allow macro enabled workbooks. So what I would like to do is push a button and open all of the spreadsheets, accept the update workbook prompt then save and close the files.
I've seen a similar command developed by someone using the Soildworks API but updating design tables in solidworks takes ALOT of time to run compared to just opening and closing spreadsheets.I am using Visual Studio 2010 Beta 2 along with Excel 2010 Beta 2 (I like to have the new things)

im having a problem with replacing some files in a folder, i have made a Auto Upater for a application im making (so beta testers can test it and also get updated stuff to test) now i can replace the Main application.exe with
If File.Exists(Application.StartupPath + "\test.exe") Then
File.Replace(Application.StartupPath + "\update\test.exe", Application.StartupPath + "\test.exe", Application.StartupPath + "\test.exe.old")
End If
This is after i have unziped the main update.zip folder it downloaded
but i also have a Data folder in the Main application folder and inside the new update\Data folder its has updated files now i cant list all files to replace like above as i want be replacing all files all the time, so im looking for something like you have on windows (would you like to replace files) without the prompt its just replaces them, so really im looking for a move and replace without prompting
i have tryed
Directory.Move(Application.StartupPath + "\update\Data", Application.StartupPath + "\Data")
and
Directory.Move(Application.StartupPath + "\update\Data\", Application.StartupPath + "\Data\")
but it errors saying the folder exists and i cant delete the folder as it will have files in that DONT need updating

I am looking to get some information on updating my own applications. Because what I have to do at the moment is replace the files every time it changes so I would like to know what are the options available starting with the easier ones or does it involve any third party applications. For example I have noticed some applications checks the files before it starts up and then asks a user if he wants to update it

I need to develop a service and install it into a w2003 box to read excel files a then process its info. The process is as follows, users will upload excel files using FTP and then my service must take those files, validate and then update a SQL Server DB.
The application runs fine on my computer but on the server it asks for the libraries but when I try to install the MS office 2003 Primary Interop Assemblies, system displays "Please install Microsoft Office 2003 before installing the product".
I'd prefer to stay away of any server upgrade as we should require OKs, etc.. so, is there a simple way to just read excel files without having to install any update in the server.

I have a little vb.net script that will copy a file, set its attributes to Normal, update the file time, and then set back the attributes to match those of the source file.
If IO.File.Exists(Destination) Then IO.File.SetAttributes(Destination, IO.FileAttributes.Normal)
IO.File.Copy(Source, Destination, True)
IO.File.SetAttributes(Destination, IO.FileAttributes.Normal)
[code]....
I however I'm encountering a quite strange problem. On some configurations, IO.File.SetLastWriteTimeUtc triggers an UnauthorizedAccess error, although the IO.File.Copy instruction worked very well.

I am using an update panel and when I click a button it will update all the panels. updapanel1.update() is very simple, but my data is not updating unless I hit the button twice. My gridviews shows data for a selected user, and then all the grids reflect that users data. works fine all the update panels work for the gridviews. Now for somereason when i try to do a row count and update the panel with the summary, it does not work, i get either the previous users summary or if i hit update again for the same user i get the correct data.

I have a gridview that is set to a sql datasource, it is generating the columns automatically. If I add a column to the table it is referencing, it will draw that column and display it, but it does not update the insert/update commands to include the new column. Is there any way have it rebuild those commands automatically?

oldSr.Address_Line1 = sr.Address_Line1

The helper function I have written seems to do everything I want apart from update the db. Stepping through the code, the oldSr is updated by the new sr parameter but no update on submit changes.

I have an update panel that has a table in it with 4 images. Every few seconds a new image is shown. All this works but when the image changes the whole page is refreshed. I am using Visual Studio 2008 and VB.Net 3.5.I only want the images in the updatepanel to refresh. How can I do that?
UpdatePanel Code:
<asp:UpdatePanel runat="server" ID="upImgSwitch" UpdateMode="Always">
<ContentTemplate>
<table height="200px" width="100%" border="0" cellpadding="0" cellspacing="0">

Here's my code
Dim suppQuery As String = "SELECT [Supplier ID],[Company],[Last Name],[First Name],[Email Address],[Mobile Phone],[Office Phone],[Address],[City],[ZIP/Postal Code],[Notes] FROM [Suppliers]"
Dim dsSupp As New DataSet
Dim daSupp As New OleDbDataAdapter(suppQuery, cnPharma)
[CODE]...
It errors on the da.Update line and by the way if it helps, the text fields are a product of datarowview. that is when you select an item on the listbox the details of that appears on the text fields. and my goal is i could edit those text fields and save them.
