I am having a problem where when I save some text to an XML file it overwrites originally what was in there, I want to be able to add to the file. The file looks like this:
<Incident>
<name></name>
<Department></Department>
<Incident></Incident>

I am having some troubles with a project of mine. Its a basic financial manager for windows mobile 5 using VB.net. Everything works fine, however, when a value is saved in xml, it will be overwritten when another is saved. I want it to add these values instead of overwriting them entirely.[code]

I'm trying to edit an existing xls and just overwrite it without a prompt to overwrite. I thought it was something like Excel.DisplayAlerts = False but that's erroring with 'DisplayAlerts' is not a member of excel.
So this is my current closing code that doesn't work.
oBook.SaveAs(ExcelFilename)
Excel.DisplayAlerts = False
oBook.close()
oExcel.Quit()
I currently have two applications. The main app and the updater app. When the main app checks his version with the webservice and it is out of date, it will download a zip archive and then start the updater. The updater will extract the zip archive overwriting the old files of the main app.
Is it possible to do this without the need of a 2nd app, in this case the updater? Can you like, store your application in the computers memory and overwrite the files?

The following code writes some data on an xml file. If I want to write on the same file twice the code overwrites the old data with new ones. How do I update the data instead of overwriting them? (i.e., write at the end of the xml file instead of overwriting the data)
Dim XMLobj As Xml.XmlTextWriter
Dim enc As New System.[Text].UnicodeEncoding()
XMLobj = New Xml.XmlTextWriter("C:" & current_scen & ".xml", enc)[code].....

i have made a program that takes info from your registry and uploads it so I can fix it and you can download the new version of a key that makes things work faster.... when someone uploads a file, it works good, and i can look at the ftp's text file and see it, but every time someone ELSE uploads something, it overwrites the previous text file and makes another one, which deletes the first one. i would like so that when another person uploads something, it will just be on the second line then third, so on so forth.

I checked the contents of the array at the end and it only held the last records within the text file, which suggest that it is overwriting the array, how can i prevent this?
I'm creating an app that will be run via scheduled task, it will save an XLS file with the following naming convention:'S14-PROORDEREXP-Thursday' (the Thursday will change depending on what day of the week it is)I have the following line of code to save this excel file:
VB
If gstrJob = "S11" Then
xlWorkSheet.SaveAs(gstrFilePathS11 & gstrFileNameS11 & gstrFileTypeS11)
Else
[code].....
this will work fine the first time this scheduled task runs and there are no existing files but at the end of 1 week when I will be overwriting the existing files, how do I tell the application to overwrite the existing files without waiting on a yes prompt from me which it does in debug mode?
The program I am making uses a save dialog box and when I save a file it works fine. When I save and overwrite the file it seems to append the data. For some reason it keeps all previous data and just writes the data again. I'm using the XMLWriter to save the files. Is there any way of fixing this?
View 5 RepliesI have a dataGridView and tied it to a button that saves every time you click it. and every time you click it, I want to write a line to a txtfile that displays how many records were changed and the date that they were changed. Everything works fine but every time a save has been made it over write the previous entry on the text file. Here is some of the code.
If changes > 0 Then
MessageBox.Show(changes & " changed rows were stored in the database.") ' changes shows how many entries were changed
swDate.WriteLine(changes & " record changes on " & entryDate) 'entryDate is formated as date with value of "Now"
Else

I am getting the right results in the text file except it over writes previous entry's so there is only one entry saved in the text file at any given time. I want it to keep building the text file so every time something is streamWrited the previous things in the text file stay there and it add to it. Looking at my problem I cant really justify or implement a For Each..Next or a Do While..Loop. My vb knowledge is limited so go easy on me.
I made a program which uses sample.dll. The program communicates with this .dll and does various tasks. Now, lets say I developed a new dll (an update, pretty much). Can I just give my users a new copy of the .dll or do I have to re-reference it in my project and then compile my programs all over and then give them a new copy of the entire program?

I have developed a VB.NET application that generates code in a specific format. It has a multitude of features and everything works great. I recently added the ability to save generated code to a text file as well as the ability to load those text files into the application. I am looking to add one last feature (perk). I want to include a bunch of pre-coded text files with the application, that new users can load and use immediately. As of right now I have the application creating the directory they will go in, but can't find anything on how to include the text files and have them placed in that directory. This application uses one-click deployment (in case that matters).

View 5 Repliesi have a program that when you click a button it randomly gets a random line from the file and adds it to a textbox. Well when i give ppl the program it needs to have the .txt file in the same dir right.
But how would i add the file to the program itself ?
Or Add the contents of the file to the project ? maybe a class or something idk.
How i can do this? Add a path on my computer or the resources
