I'm using Visual Studios 2008 to write a small program that writes to a file. The program works fine until I run it on my server at work, where for some reason it adds a "next line" (like vbCrLf command) at the end of the second line in the .txt file. [code]

View 8 Repliesreading and writing files. Let's say I have a text file with multiple lines that I want to be read into my visual basic program. The first line is displayed in textboxA while the rest of the lines are displayed in textboxB. How do I accomplish this? Am I able to use the peek method for textboxB but somehow tell it to skip the first line? Now textboxB is obviously a multiline textbox and I want the user to be able to type something into another textbox (textboxC), press a button, and it will be displayed in textboxA. How do I make the text in textboxC get displayed on the first line of textboxA and move all the other lines down the list?

This question only applies to files of line-terminated/text strings.[code]I suspect that ultimately, I will generate the myfiles version of the HD file as I write it to disk,but at this point in my VB.net 'skills', until I can prove what I've written by reading it back and having control of it in my program, I can't assume anything about the data/format/file that I have written.
View 12 RepliesAll i am trying to do is read and write files to a shared folder on a network in visual basic (VS 2010). I can go to the folder through windows without a problem and without being prompted for a password. However when i try to do it through visual basic, it cant find the directory. Here is my small snippet of code that i (hope) is telling me that the program cannot connect to the folder. [code] Are there any known issues with VS 2010 that may cause this? Maybe something else in my code that could have an effect? This is in my form_load event though, so it is literally one of the first things that runs.

View 2 RepliesIm trying to write a loop that will read through a number of *.csv files in a folder and then stuff the data into SQL. The code works and will happily put the data i want for a named file into SQL no problems. So when i had that working i then tried to loop it so that it would do the same for all files in the folder until all files had been done, and not error out if there where no files etc.
Maybe im tired (well, i am) or not had enough coffee but i just cant get this to work, it should be simple - i know it is infact, but its making ME feel simple.i think i should have an integer count in there, but similar examples ive seen dont use one. Also when trying to open the path i get an error at runtime "the path is not of a legal form"

Public Sub ImportCUSTCSVs()

View 19 RepliesI am using Visual Basic 2008 Express Edition. Some of the programs I am writing make extensive use of External files (saved games, data, item lists, etc.) I could use an easy way to get these files to ride allong during deployment (cd mostly). adding them to the resources works for some static pictures, but custom structures into lists of info to read and write from are beond that features abilities, same with the settings feature. I have found in other help referance to "MageUI.exe" so is downloading a .net SDK my solution or is there a better trick I can use?
View 2 RepliesI have recently decided to give .net another chance, but i have a few questions about it before i get really into it. RE: Files, I use random access files to store data as opposed to databases (namely i don't see the need for a database for storing so little information(records <200 max) knowing that it is an older system and less "cool" i don't care...) Will vs2010 express read, write to random access files? Would it be done kind of like vb6 (which is my current vb version)? I will be needing to print the text of rich text boxes, is vs2010 express capable of doing this?
