Saving Some Simple Strings (from InputBoxes) To An Xml File
Nov 2, 2011
I am working on saving some simple strings (from InputBoxes) to an Xml file.I am also at the same time displaying these file entries in a Data GridView. My problem seems to be that as soon as the XmlDocument ("doc") is saved, a dialog box is displayed as follows: This file has been edited outside of the source editor I am getting the dialog, and 2) why I cannot run the routine again (without exiting the application first!). [code]

I am creating a programme, where I type a sentence into a textbox, then send to an XML file to be stored, which works fine.However when I go to write a 'new' sentence in the textbox and save it to that xml file, and it overwrites the original sentence.I am using what is called a serializable data class to save to my XML file.

I recently made a simple pseudo-encryption program that changes each character into another. It is capable of encrypting and decrypting a string. This can also be done to any text file as well. The characters range from ASCII 32-254 (This on it's own may be an issue because of #127 being DEL).
Because I believed my own coding may be at fault, I attempted this with Triple Des with identical results.For Triple Des, the requirements for en/decryption was:
Encrypt: String to Byte
Decrypt: Byte to String
And to change them either direction, I used UTF8. I also attempted ASCII and UTF32, but I don't know what I should do. I am considering dropping this but I want to learn problems like this because I am currently in college and haven't started my core classes for programming yet and want the head start.
The point where I have come into a problem is attempting to do this to another file type like an image. I looked at the results from encrypting then decrypting and the results were similar, but it seems file encoding must be the culprit.

I try to keep it short - so far I got an app. which receive, compare and send STRINGs back and forth. Due to the fact that I am not too fit in VB, I realized it via a SELECT/CASE method. But now, I would like to allow user to add new STRINGs from the user plane as well (before it was done by myself). I can imagine, I need a database for it. Which one would do the job best? I need only two columns, where my app. can send a coulmn B string back, after it recognized a column A.

Are inputboxes nolonger dynamic in size?in VB6 I could list say 12 months of the year along with month numbers and ask the user to select a month number. So the code would go:strmsg = "1" & chr(9) & "January & chr(13) & "2" & chr(9) & "February" & chr(13) e.t.c. {for each month} & "Leave Blank To Cancel". This would list Month 1 to 12 plus the last line.
There appear to be 2 problems using vb.net:
1The input box does not grow virtically to accommodate a dynamic number of lines
2The chr(9) function to produce a "tab" does not appear to work, whilst the chr(13) (Return) does work

Do
strInput = InputBox(" Enter Your 16 Debit or Credit Card Number ")

Say I have a List(Of Tag) with Tag being an object. One member of Tag, Tag.Description, is a string, and I want to make a comma-separated concatenation of the Description members.Is there an easier way to do this than to read the Description members into a List(Of String) and then use the Join function?

MySQL databases exists for saving values as strings (text only). Is there any way that i could store files with the same speed as a mysql command ? I know that it depends on the file size but lets say that the file is "Avatar.jpg" 50KB... I ve tried FTP but this is not what im looking for. e.g. You want your users been able to upload a file like the [Add This Attachment] button does in dreamincode.net and you dont have any background on PHP/HTML/Javascript/ASP.NET just VB.NET and the basics of MySQL plus you dont want to use it for a website. How do you accomplish this? Something silly that ive tried was opening an image as text then update the mysql server with that text but it didnt work backwards after i wrote the text on the file and oppened it ...it said that the image was corrupted.

I am new to using visual basic 2005. I have a tutorial book and I have followed it but it does not help me understand. I have a limited understanding of the net framework and the drag and drop features.
What I want to know is this: How do I make a simple name and address tracker file that I can enter data and save it as a file. The book does not cover this proceedure but It is what I want to do.
IE: Start VB2005 start new windows app. Name (whatever) drag 2 label's and 2 textbox's and one button for saving data entry. I want this program to enter name in textbox1 (press enter) then enter address in textbox2 (press enter) then save file (whatever name) when you click the button.

I'm looking to take a small snippet out of a wave file which I can do by reading in the headers, calculating time in to samples and selecting that data back to another file with the headers appropriate for the new smaller chunk.
My question though is does anyone use a nice small free library that does something like this. With the numerous different versions of wave files and headers not matching I'm trying not to re-invent the wheel and if someone has done it already and can handle these discrepencies that would be amazing. If not I'll fire up the kettle and get the coffee on.

I am creating a shell for a FORTRAN application which reads a tab delimited text file.Because I am using Excel to manipulate data, is it possible to use the Excel Automation features to "save as" a tab delimited text file?The only method available seems to be a unicode text format, which does not work. Or is there another format that mimics tab delimited so that the FORTRAN application will read such a file without difficulty?

I have an asp page with vb.net code that will query a database and present the user with the number of records that exist that need to be exported along with a button to export them. After you push the export button, it will prompt for a location and filename. But after that, it will not refresh the page with the new counts that now exist. Or in this case update the count to zero for the button they clicked.
[Code]
So how can I tell the page to refresh with the new counts. It almost seems like I need to tell the process to wait until after the user has finished finding the location and saving the file but I don't want to add a generic threading.thread.sleep in, I want it to only wait until they are done and then refresh the page.

I have a dbase.txt file with some data in it. i.e -
Institution Course StudentID
XZY ABC 2010-1111111 "the spaces between columns is one tab space"
XYZ ABC 2010-1222222
XYZ ABC 2010-1333333
I want to perform simple SQL like operation - i.e -
SELECT * FROM dbase.txt or
SELECT Institution FROM dbase.txt WHERE StudentID=2010-1111111 and an insert operation like -
INSERT dbase.txt VALUES (XYZ ABC 2010-1444444)
I have written some code which is not even closer to what I mentioned above. My program can read only the whole text file. There is a menu, but not functioning well, as well as my write function which is not working at all.
Below is my code -
Imports System.IO
Module Module1
Sub Main()
Dim intInput As Integer
Console.WriteLine("Main Menu")

Getting a vibe that my VB is cursed. All I want to do is load a textfile and have the text appear in TextBox1 But no. I have looked at 3 different tutorials and I have tried copying their code word to word but still!
