VS 2008 : Calling A Fortran .exe That Calls A File - File Not Found?
Jul 6, 2010
I am trying to run a fortran .exe in VB with the Shell() command. The fortran .exe, when ran, it asks you for a file name. It works perfectly on it's own, but when I try calling it through VB Shell(), it does not work.. (i.e. I cannot get VB to get the file name in it.)
Added info:I am using VB9 but I'm writing in compatibility to .NET. As for the Fortran .exe, when you call it, it opens a command window where it asks for a file name (which I got as a string in VB and I'm trying to pass it in), then you press Enter and it's done. Basically the .exe takes a text file and creates a new text file. We've also tried adding & mystring when calling the exe, but it gives a "file not found" error.

I am running one fortran exe in .net application(calling from command line with the help of system diagnostic process). If we directly click on fortran exe, it shows inputs to enter for fortran in command window, after input entered it gets executed. We want same behaviour but want to run fortran exe from .net application, If we click on button in vb.net form, this exe should get called and should show inputs to enter on the command line, once inputs entered it should execute. How to achieve this with .net application? Right now, after clicking on button in vb.net form, exe get's opened in command window, but it is blank, and gets hanged. [code]

I have a subroutine that was written in fortran that I need to call from VB.NET where all of my other functions are written. I did not write the fortran, and hardly know fortran. I am getting the below exception on my dll function call and don't know how to fix it. I wonder if it is due to incongruent variable lengths? I have the source for my fortran and compiled it using the g95 compiler. I have tried compiling it with a flag on which is supposed to force all of the reals to 32 bits (-r4). It weirds me out that you don't seem to be required to initialize variables before use in fortran. I thought it was supposed to be a ridged language.

I am calling a Fortran dll from vb.net. It works when I call it it one time only. When I put that in a loop, it works for the first time and second time it quits the program. How can I run this in a loop?

I have a solution which upon a button push, loads a PDF into the application for viewingThe loaded PDF is an index page linking to other PDFs. This all came off a CD of a VendorMy client want me to create a "Job Book" of all the CDs from these vendors.Here is the issue.When select the button for a particular document, the front page of the PDF (Index Page) load fine. The loaded PDF has buttons as links to the various pdfs so when I select a button within the loaded PDF I get a message stating it cannot find the pdf requested. The buttons within the index pdf are all set to relative path so all the folders should be available. but alas the program does not find them.

I have a program that looks for a file named 'license.dat' upon startup. The program first checks the directory it's in, and if the license file isn't there, it prompts the user to select the license file with a file browser dialog. I have tested this code and confirmed it working in a number of different OS environments.Recently, I received reports from two users (one in Germany and one in Italy) that the program can't find the license on their computers, even though it is present in the program's directory and they manually selected it with the file browser dialog. The only commonality I'm seeing here is a lack of English OS, but beyond that I'm stumped.This is the code I'm using:
If System.IO.File.Exists(System.AppDomain.CurrentDomain.BaseDirectory + "license.dat") = False Then
File dialog code goes here

Using VB6 to create a file and then open the file just created fails when run on a Vista client with Windows 2008 Server. The same code will work when run directly on the Windows 2008 Server or when using an XP client. If a Sleep 10000 is placed after the close, the program will work. What is the problem here? The code is as follows:
Option Explicit
Private Declare Function GetTempFileName Lib "kernel32" Alias "GetTempFileNameA" _
(ByVal lpszPath As String, ByVal lpPrefixString As String, ByVal wUnique As Long, _

I'm developing a very simple app that does nothing more than launch two other apps. I'm developing this under the .NET 2.0 framework for WinCE 5.0 in VS2005.No matter what I do, I keep getting file not found exceptions not handled, and the program crashes. (Yes I should probably have a try/catch block, but this isn't the issue.)
Here's some code
fullPath = Path.GetFullPath(drivePath)
Me.Label1.Font = New System.Drawing.Font("Tahoma", 6.0!, System.Drawing.FontStyle.Regular)
Me.Label1.Text = fullPath & strDrivePath
Now, the label change here is not important, I only do this to output the full path of the directory, and strDrivePath is "whatever.exe"
If Directory.Exists(fullPath) Then
If File.Exists(fullPath & strDrivePath) Then
Me.Label1.Text = "EXISTS!!!"
[code].....
The irritating thing is after getting and displaying the full path (I know it's there) I check with the first IF to prove to the program it's there. No problem.I then use the second IF to prove to the program that the executable is there, and change the label output on screen to prove to myself the code is executed. The label changes. The file is there.
Then when I run the program, File not found exception. It's driving me insane. I've tried in multiple OSes (Vista and CE 5.0), I've tried in directories with spaces and no spaces, I've tried using Process.Start() and setting up the file details through the info command.I've tried putting a path in there directly instead of using variables. I've tried wrapping the whole kit and kabodle in quotes like this Shell("" & fullPath & strDrivePath & "" ) and like this Shell("""" & fullPath & strDrivePath & """").I've searched high and low on forums around the globe, including multiple threads here and I just cannot get it to work.

I am calling the OTA API from HP Quality Centre and one of the calls requires sending a NULL. This is the actual line of code:
stepF.AddItem(NULL)
This works perfectly in VBA and VB6 but VB.NET doesn't accept Nulls. Anyone know how to fix such an issue?

I'm trying to create a "File Not Found" error to display if a file the program is looking for is not created.Example:
Dim ProcessProperties As New ProcessStartInfo
ProcessProperties.FileName = "filename"
ProcessProperties.WindowStyle = ProcessWindowStyle.Hidden[code].....
I also need help creating a text box, that will submit information to another source (like echoing to a command prompt window). I'm trying to add a killtask option where the user can enter the name of the tast (such as notepad.exe) and press 'Submit'. The button will then send a code (killtask -f notepad.exe) to a command prompt window.

I had the following piece of code working for the last few weeks and earlier today it seems stopped working.I have the code in a try/catchh block and in that try I create a file, "Build.bat" with code in it that will get it to do some oracle/sql wizardry
If File.Exists(Application.StartupPath & "Build.bat") Then
Shell(Application.StartupPath & "Build.bat", AppWinStyle.NormalNoFocus, True)
End If
After stepping through my code I noticed that the catch is executed at the shell line, so I put it in an if statement to see if the file exists and it always comes up as true, but on the next line I still get a File not Found error.
Try
Dim BatFile As New StreamWriter(Application.StartupPath & "Build.bat")
Dim SQLPLUS As String[co

I am trying to run a process on a remote computer using pstools. Anytime I use rocess.start to call any of the pstools from my system32 directory, I get a file not found error. I can call other executable files from the same directory without a problem. Are the pstools (psexec, pslist, pskill, etc) blocked from being run in VB somehow?ere is the code I am trying to use that generates the error "File not found"

I'm working with a connection to a Access db. I noticed that when the mdb file is not found in the location it should be, an exception OleDbException is thrown. I would like to create some kind of form where the user specify the new position of the Access mdb file to continue to work. Then, it would be useful to save the new location as well I suppose. But, where do I have to handle that exception?
