VS 2008 - Writing To XML On Every Loop
Aug 26, 2009
I am very close to finishing this function, what I am trying to do is a for loop which:
1) Grabs the value
2) saves the value in an .xml file for later use
Currently when I use a for loop to feed in my function I overwrite the hiddenFields.xml on every pass, instead of adding to it.
Calling function:
vb.net
For X As Integer = 0 To postingHiddenFields
Dim hiddenFieldsReturned As String = functionDealWithHiddenFields(HTMLResponse, postingHiddenFields, X)
Next
[Code] .....
So basically on every pass of the function I'm overwriting the values instead of adding to them.

This windows application finds the amount of your pay if your pay is doubled each day, starting with a penny a day or a nickel a day. Instead of one month's salary, a boss offers her new employees a penny the first day and experienced employees a nickel the first day under a new pay system. Each day the pay will double.Restriction: The minimum number of days for the pay period is 19 days for the new employees and 16 days for the experienced.

Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.
Option Explicit On
Option Strict On
Imports System.Globalization

i'm running Visual Basic 2008 Express Edition (latest service pack ... 9.0.30729.1 SP) on XP Pro SP3 with .Net Framework version 3.5 SP1 I have a rather large project I've imported from Visual Studio 2003 (Standard).The project compiles and runs just fine ... my compiled program itself never crashes.
But while I actually have the code up in the IDE, and simply adding/deleting code the whole IDE will randomly crash (usually without warning) and I loose my changes since last save.If/when I do get some hint of why it crashed, I get a window about illegal whitespace or something.... but that's rare ... usually it just crashes without warning and the whole IDE completely shuts down instantly. just deleting/adding a character is enough to trigger it maybe once every 30 minutes.
This is on a computer that is otherwise very rock solid .... no other program ever crashes, etc.

I tried the 2 listed answers to this problem but neither worked.I'm writing with VB 2008 Express under .net 3.5 Project going well - no problems until I needed to change the form design again. The project still runs OK - the "Form1.vb" and "Form1.Designer" files are still there and look OK, BUT the "Form1[design]" tab is missing - how do I get it back?

Okay, I have a structure that contains numerous elements... mostly strings, one or two integers. I maintain an internal array of that structure. The structure contains ONLY data elements, no code.I want to save the data to a file. I know that I CAN use StreamWriter.Writeline()to put out a formatted string for each element in the array. But is there any way to simply open a binary output file and save each structure, one after the other? And conversely, to load the array again in similar fashion? Something similar to this in intent, though I realize the code below doesn't work.
[code]...
To repeat, I want to write an entire structure to a datafile quickly and easily, without having to save each member of each element in the array. And conversely, to read the data back in the same way for easy loading of the array.

Ok so there is an XML file for a program that already exists that stores a list of files along with other information.I need to open this file and read the file names and then potentially add files to it if they DO NOT already exist in the file.It is very important that I not wipe the XML file and have to write it from scratch every time.

I'm trying to read 5 bytes from a file and then do something according to what has been read. This is my code (I'll explain in a bit what's wrong):[code...]
It reads the 5 bytes I added to the encrypted file, but I want the CryptoStream to start from the sixth value and then copy the original bytes into the decrypted file, but it gives me an error:
Padding is invalid and cannot be removed.That's why I'm trying to make it read from the sixth value and then continue copying normally, but I'm stuck.

I am coming across a lot of odd and annoying problems in this program and have almost had enough lol.
I cannot figure this one out for the life of me. I have used streamwriter a hell of alot of times and never once experienced this. But basically I have a string array and I need to write the entire array to a text file with a new line for each array item. So I have gone ahead and done this:
[Code]...
However the outcome is the text file only contains 1 line and that line is the last item in the array yet I know the array has got at least 50 items in it.

I found the following links to fill a listview and then write it to a CSV.[URL]..And I modified the codes and created the project which is attached to this post.
The project works OK but my only problem is that when it creates the CSV file, columns are not created in excel. For example if I expect the data to be placed in A1, B1 and C1 cells, the data will all be placed in A1.

I have a structure in memory which is working fine - now I need to write this entire structure to a file. The below code almost compiles, the problem is that "mstaRecordInfo" cannot be changed to a string, probably because of the Date field. I've just spent over an hour experimenting and searching the web but have gotten no closer to a solution.

This time i have a RTB (look.text) that contains no more than 12 lines (it updates according to a listbox but it will never exceed 12 lines of text). The lines contain numbers like this:2345,0,0,1,36,... and the last line will always be a number like: + or -123456789I also have 12 textboxes (a0.text to a11.text). How do i write each line from the RTB in a textbox?-i can't show you my code because it looks stupid and no matter what i tried i always ended up getting the same error "Index was outside the bounds of the array"-

How do I approach this? I'm wondering how I could write a new date to a label every four weeks. If I establish a start date, saved somewhere, I need the label to say 'Your next payment is due on: (a Friday, every four weeks ahead). Is there some way to use the date time picker using date difference? I would like this to continue updating so it shows a new payment date every fourth Friday. My difficulty is that the calculation is 13 payments a year, not 12 so I cannot just pick the same date each month.
