VS 2008 : Calling A Fortran .exe That Calls A File - File Not Found?
Jul 6, 2010I 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.

Feb 21, 2012The cmd file calls a web service that is used to select specific data. When I run the .cmd file manually (as in clicking on it) it runs correctly an saves the file with the information in the appropriate location. However when i try to do this with the .Net app the file is saved however there is no data in it. Why is it when I physically click this same .cmd file with my mouse it works but not when I call it from my application.

View 11 RepliesCalling .exe File From VS2008?
Aug 8, 2011I am programming in both Matlab (Matlab2011a) and Visual Basic (VS2008).I've created a .exe file from my matlab code. It works well when I click on it with my mouse. But I need to run it within Visual Basic. I know it's possible to call .exe files with Shell() or Process.Start(), and it works well for files such as firefox.exe or notepad.exe.
However, it doesn't work when I call my own .exe file ... It's weird because when I look to the Task Manager while trying to call it (within VB), I can see the process starting and ending, but its output doesn't appear.

VS 2010 Calling Powershell File
Jun 9, 2011I'm currently having issues calling a .ps1 file in my vb.net project. The program is supposed to provide a simple way for end users to unlock Active Directory accounts. The vb.net project is simply a text box with a button. Users will type the username of the locked account. When the button is pressed, the program writes whatever is in the text box into a CSV file. The CSV file has a samAccountName column in it. After the file is written to, the program then calls a Powershell script that reads the CSV file and unlocks the account based upon what is in the file.The program does everything it is supposed to except for calling the Powershell script to actually unlock the account. I've tried a Process.Start(filePath) which would open the file, but opened in notepad and didn't execute anything. Right now the program is calling a batch file which is supposed to run the script in Powershell but that attempt also failed.

May 13, 2011Example:
Two files - TestClass.vb, myForm.vb
TestClass.vb looks as follows:
Imports System.Threading
Public Class TestClass
Private myClassThread As New Thread(AddressOf StartMyClassThread)
[code]....
The result:Application runs, no errors or exceptions.Displayed is the listbox and the Start button.I press the start button and a msgbox says "Not Invoked" as expected and upon clicking OK to that msgbox "Start Button Pressed" is added to the Output listbox control.Immediately following that the msgbox pops up again and says "Not Invoked". I was expecting "Invoked" as a separate thread is trying to use the Output listbox control.Of course this results in the Output.Items.Add being attempted which results in no visible result as the thread is not allowed to directly update the UI control.

50 Random Circles With Different Colors?
Feb 9, 2011I am working on a program to generate 50 circles starting with the smallest in the center of the form. The circles do not over lap and the appear to grow outward. Each circle has to be a random color. I have the code that generates what I need but all the circles are the same color. I was thinking about either using an array to hold each circle and color as to not assign the same color to all of them but not sure about putting a graphic in an array. I also think maybe a nested loop of some sort but was unable to figure one out.
Private Sub mainForm_click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Click
Dim penColor As New Pen(Color.FromArgb(Rnd() * 255, Rnd() * 255, Rnd() * 255, Rnd() * 255), 2)
[Code]......
This works to do what I need to get done, I just need each circle to have a random color as it is drawn.
