Running .exe's; Read File Into Array; Relative File Path
Apr 22, 2012
I am trying to create a sort of 'personal code library' in visual studio 2010 where the form displays a list box of certain project files in vb that I have made in the past and when selected, a button can be pressed that launches the .exe files of those visual basic program project files or displays the source code (.vb file)
I am trying to read and display a file using MapPath as follows :
Response.ContentType = "Application/pdf" Dim FilePath As String = MapPath("../Document/123.pdf") Response.WriteFile(FilePath) Response.End()
This procedure will work fine and display in the browser. However, if I save the file to C:Document123.pdf, how can I access this file using relative path in MapPath function. Is there an option to access the file which is saved out of IIS server? I am using vb.net 2003.
Only, I would like to place the pdf file in the project's folder and that would open wherever the project's folder is (on the Desktop, a USB port, anywhere).
I have a form with a tabbed control on it. Each tab in the control simply loads an existing file in a reader to display to the user. I have added the files in a folder in my project. When I debug it works great. However, when I publish and move it to another computer, the program runs fine but none of the files show in the tab control tabs. The files do come with the solution when I publish.[code]I know there is a way to make the file path "relative" but I cannot figure out how and there really isn't many resources available to explain how this can be done.
I have completed my VB project using vb 2008 express edition..I am not able to create a set up file for my project and I think it is because of the file path i have provided in my program
dbSource = "Data Source = C:Documents and SettingscfadminDesktopLead_managementLead_Management_ProjectLead_Management_ProjectLondon.mdb"
The above path is a fixed path which connects my program to the database. Now when I create a set up file and try to run on another machine it wont recognize this path . have placed the database in the same folder that of the program.
Firstly, I'm a Chinese Beginner of Visual Basic. I try my best to express my worries and demands. If anything is vague, I want to design a program like this: when clicking the button, the computer will play certain sound. Like this:(VB 2010) Private Sub con_sndplay_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles PLAY.Click
In vb.net, when writting an application, I want to access a batch file that has been added to the project. My question is how to I find the relative path of this file to access it? I have used relative path on the ASP.NET side, but not on the application side. The properties that I am finding regarding the current directory and running directory and the likes are all for the bin directory its in. While I can use the CurrentDirectory() property and go up two parents (....) in the development environment, when I install the application, the structure is not the same. As in the output is in a single folder, not tiered.
Example. c:projectsMyAppindebugMyApp.exe is the running directory My file I want to access is at c:projectsMyAppvalidate.bat so "c:projectsMyApp" is what I am trying to capture.
Reading a .txt file in VB.net. My file path is C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt.
This is my line of Dim LoanOptionsFile As String = "C:UsersMyLilMulePepeDocumentsVisual Studio 2008Projectscurtain_calls.txt"
I can read the file when I run the program, but how do I write the file path so that someone else can download my program and file and read the file on their system?
i have created a batch file and have added it to the project using add items. Basically what i am aiming at is to execute this file on a button click action. I am using System.Diagnostics.Process.Start("hello.bat") command to run this file i have changed the build action to resource for this batch file. But when i run this program, it is not able to locate the batch file. I am required to give a relative path as the path my vary from machine to machine. how can i make this file accessable using a relative path?
However I want to let users install the program wherever they want, so I changed that line and others to:
System.IO.File.ReadAllText("data.dat")
Which works great, until you do this:
System.IO.File.ReadAllText("D:/X/Y.Z")
As soon as I put a fixed path into the ReadAllText function it changes the relative path to D:/X. Which means the following function looks inside D:/X instead of the apps directory:
System.IO.File.ReadAllText("data.dat")
And complains that "D:/X/data.dat" is not found. How can I use relative paths but also read from full file names, for example from an OpenFileDialog, without VB changing my relative path, and breaking it all from then onwards?
then i need to read in a file into an array on the structure above, and pretend this is the file which has 3 people

I'm trying to read a log file for a game so I can extract certant info from it and track my stats as the game is running, but I keep getting access denied error for the log file. I would also like to have the log read only after it has been changed but the event handler never fires. I'm assuming it has to do with the access error. Can someone give me an example of how to watch a text file that's in use by another program and read it after it changes. The code I have works if I open the file in notpad, change it then save it but not when the game is running. I did it once before for the same game but lost my code and there are other programs that parse the log file so I know it can be done.
I am having a big problem with deleteing a file form the server. I have the filename for a image stored in my SQL database. the problem is i am getting an error of "Illegal characters in path. " Here is the code below:Everything is working fine until the delete command.

I create a string array from a bunch of files that were dropped on a control after that i use a loops to pass that data into an array of my pictureObjects object (just stores filePath info and some other things).for some reason after it's been passed to the control the "My.Computer.FileSystem.RenameFile" doesn't seem to work at all... it's a valid file name and everthing.
Dim sFileArray() As String = e.Data.GetData(DataFormats.FileDrop)

I have been trying to research how to get a file (basically a csv file) from a url to an array and my search has come up with some examples, but not quite what I am looking for. Would appreciated any direction and or other examples of folks that have done this before.Basically we have a cloud computer set up (Hadoop) and the output of some of our processes is what I am trying to get to.[code]....
I have a function that reads a character array from a file, converts it to a byte array, then writes it to a Network Analyzer. The problem is the conversion takes forever as the size of the array is about 287,000.... Here is the code..
Code: Dim objSR As New IO.StreamReader(strPath) Dim charA As Array = objSR.ReadToEnd.ToCharArray ReDim bytedata(UBound(charA))
The file I need to read in is a square 8x8 or NxN. the chars are separated by spaces and at the end of the line I believe a crlf. When I try to read in the file i get the crlf's when i use this [Code]
Is there any special way of reading a pdf file into a byte array? The reason I ask...I want to fax a pdf file using faxDocument and FaxServer. My current code is working fine for everything else. Now I know that in the documention it says it should not work for pdf. But I can get some pdfs to send and some do not. When I fax a pdf through windows, it works. [code]....
