View 1 RepliesI Have a PDF Folder containing pdf files with the names ( sp_1.pdf , sp_2.pdf etc.....)
In my word files , I have the text : " and it was created under the rule sp_1 in order to acheive the level we are working for that is sp_2 "
so while reading I want the application to create an automatic link to sp_1.pdf or sp_2.pdf or sp_X.pdf if found in the pdf folder and if not ,the text stays static

On this page there is a hyper link called 'Click Here' .. when I click it, it opens another window with things in it.
How can I click this hyper link in vb.net automatically without me clicking on it with the mouse, and how do I open the window in a second web browser ?

I'm getting a suprising FileNotFoundException although i'm sure that the file exists.I simply wanted to add Logfiles(IO.FileInfo) as attachments to an email, therefore i tried to check the length of every file to detect if they must be added/zipped.This works fine if these files already exist. But if i've created them in this run, i get above exception when i try to check the length. It's oddly enough that i can write into these "not existing" files(actually FileInfo.Exists returns false) without a problem one line before.
Here is some code...

I've just recently started noticing this crash as my program has gotten more complicated. I have a few lines that look like this in my program:
Dim alines() = System.IO.File.ReadAllLines("C:deviceinfo.txt")
The problem that I am seeing is that my program is updating these files every second, so sometimes the files are being appended and or just being replaced as it is trying to run this line. Receive the error, "File is in use or does not exist." Is there anyway to put a line of code that tells the program that if the file does not exist to check again till the file does exist.
Sort of:
If System.IO.File.exists(cstr("C:deviceinfo.txt")) then
Dim alines() = System.IO.File.ReadAllLines("C:deviceinfo.txt")
else
loop
endif
Or I read somewhere that you can use:
If Len(Dir("C:deviceinfo.txt")) < 0 Then
or
If Dir("C:deviceinfo.txt") <> "" Then
Maybe:
Loop while Len(Dir("C:deviceinfo.txt")) < 0
else Dim alines() = System.IO.File.ReadAllLines("C:deviceinfo.txt")
next
I realize the danger of having a possible never ending loop in the program, but I cant think of another way to have the program wait for data and use the data immediately as it becomes available. I looked into having a wait() sub or to do system.threading, but my rational behind not using those are because waiting for 200 ms doesnt ensure that the data actually shows up, I could still receive the error.

View 16 RepliesRight now I have a program that checks login credentials against my Access(2003) database.It works, but the problem I'm having is that it's checking if the file.exist to frequently and with no real pattern. How I'm doing it isI have a My.Setting that saves the file path string as well as the connection string, during form_load I check if the My.Setting path string exist, if not then use an openfiledialog to find the file. Right now I have the database in a public drive, which is why I think that my program thinks that the file doesn't exist sometimes. This is how I'm doing all of the above:
'Some global variables commented out
'Dim log As String = My.Settings.loginStr
'Dim logCon As String = My.Settings.loginCon

View 2 RepliesWith a program I'm writing, I'm using saved data from program instance to the next. So I'm just using a simple text file to save some data. But the first time the user runs it, obviously the text file will not already be created. How can I write the code to see if the file exists? I tried to use a StreamReader but it trips up when the code runs if the text file does not already exist. And if I use a StreamWriter every time, it will overwrite the file and lose all the data. How I can see if a specific file exists already, and if not create a new one? If it does exist, then open that pre-existing file?

I'm writing a SSIS 2005 script (vb.net)in which I want the functionality to checks if a file exists if so then delete it.For testing purposes I'm renaming files to replicate an exception i.e. file cannot be read for whatever circumstance,to ensure the error handling is correct.The code works fine and catches any errors with the File.Exists(errorLookUpLog File) command, if the file does not exist/cannot be read but not with the code below using System.IO.File.Delete(lookupErrorLogFile) as when file is renamed and therefore cannot be deleted (looking for the file under it's original name then no exception is shown (see full code below, have yet to try catching specific exception for if a files doesnt exist)[code]
