When i try to run a msi using System.Process.Start("test.msi") in a vb app i get the following error. The installation package could not be opened. Contact application vendor. Msi file works fine when double clicked, tried System.Process.Start with text files and exe files and they work fine, problem only with msi files. Running vista. Also tried xp but no luck.
I'm trying this for long time and I still can not figure it, I'm trying to query a database "password" with the field to check if the login is there "login" and if it find the login in the table execute start.show() but I still geting errors.

I am looking for a method to dynamically execute blocks of code ('tasks') in a VB.Net program for a mobile robot. The bulk of the program is running in the background retrieving variables from serial ports, APIs, and the like. The user would select a task in the form of a toolbox button which pops up a dialog to enter task parameters. An accept button would add the task with the parameters to a list. The user would add more tasks to the list as necessary, and then click an 'Execute' button to start the sequence of tasks. The program would then perform the first task with the given parameters until finished, and then start the next task in the sequence and so on.
An example task would be: GPS Navigate:
A Parameter dialog opens and a destination is entered in the form of GPS coordinates. At run-time the task compares its current GPS position with the position entered in the parameter dialog. It calculates the direction to go and drives the motors accordingly. This particular task would loop until current position = destination position. Move on to next task. The code within the tasks themselves is not the problem, just the execution of the tasks.
I have made my application to start automaticly when windows start (registry ../currentversion/run/appname + path). In this mode the application start minimized and an little icon appear in the notification icon area. With this icon you can maximize the app or exit it.If you exit the app and start it again using the Menu (Start/programs etc) than the application start in minimized mode (and in this case I would like to have it in normal mode) because the setting autostart is still true.Is there a way you can detect when the application start when windows startup using the above registry or when people click on an icon in the programs menu (or desktop)?
I have custom asynchronous WebRequest class that I am testing to find out how fast the request will be cancelled and found some odd results, that starting 6 WebRequests with TPL and cancelling them right away takes 25 sec, but when I used just regular background threads it took only 5 sec.
Update: Running them without cancelling takes with Task.Start 9 sec and Thread.Start 3 sec accordingly. Imports System.Net Imports System.Threading
I'm using Process.Start to start an external command line application and using the StartInfo.Arguments method to send parameters to the application. I imagine I'll need to use a loop... but I can't figure out exactly how yet.I need to send anywhere from 1 - an infinite number of files names to this application. Each file has to be sent one after the other. So once the first one is done, I need to loop back around and past the second one.I can probably use the Directory.GetFiles method to get all of the files, but I don't know how to assign them.
I created 3 timers, i want each timer to take turn start which means timer1 stop then timer2 start, once timer2 stop timer3 start. But my code seem to be running together once i click the play button.And is there any ways to easy control how my picturebox move? Because my code for controlling it movement need to keep finding the correct number for it to move.
I've commented out various things to limit it to specifically this command (example, I can swap mklink out with notepad and it works fine). The command runs fine from a DOS window, but can't be found when I use it this way. I also tried using the SHELL command just to test and I get the same results. No idea why it can't be found, as like I said it executes from the command prompt just fine.
I am confused with the terms Build ,rebuild ,start , start without debugging in VS.NET.After writing the code what actually we want to do .We have to run directly by pressing F5 key or we have to build the solution .Usually i tried to run the application after coding and if shows any any errors i will fix that and run again .I never used build or rebuild thing .What exactly meant by building the solution .What is meant by rebuild and start without debugging.
While i Minimized the program and clossing the program , next times i start the program, it also minimized. how can i prevent this problem happen!! And i want to start the program at position which start minimized. how can i do it!!!
This is a quick mock up of what my application looks like.Trying to incorporate a progress bar. I want to be able to click "start" then the start button disappears then a progress bar shows up in its place.
I am writing an application that in the end needs to execute another executable at some point, the problem is that the executable has dependencies in the directory it runs in that are required to operate. When I use the Process.Start to run the executable it errors out because it's looking for the dependencies in my applications directory.
I tried the startInfo.WorkingDirectory option but that didn't seem to do it either (not sure if I did it right) - here is how I used that:
Process.Start("my.exe").StartInfo.WorkingDirectory = "C:Test"For the life of me I cannot find how to set the "Start In" directory. I looked everywhere, so unless it's under a different name, I'm at a loss.
I have a form where the user chooses a facility and then the list of patients for that facility are displayed in a data grid view. When I click to add a resident, the last name field on the data grid view is highlighted in blue below the last record that already exists.If I try to start typing without clicking in that cell, the facility changes - it looks like the control is still in the facility drop down box. How can I code it so that the user can just start typing in the data without having to physically click in the cell to start entering data?
We only have few meetings for Computer subject that's why time did not permit us to discuss timer codes. Anyway, my concern (I think) is just simple (though I really do not know how to start).I plan to make a countdown timer of 60 s that will start once "Start" button is clicked and will display a message box when it reaches 0. I only know the codes for message boxes.
I want to start the time in one user only because when i add a user in my listview and click the start button both of them start their time. how can only start one user only? and when i select the other user and start their time the first one that i start is continues deducting a time.
This is my code:
Public Class Form1
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load With Timer1 .Interval = 1000 '// set interval to 1,000, which is 1 second.
when I am using the following code. the kill all batch file internally calls a vbs cript like this when a batch file is called using CreateProcess() which internaly calls a vbs script like this cscript //e:vbscript xyz.vbs which intends stops and starts a service in remote PC as follows. But the service is stopping but it is not starting event though it start command is used what could be the reason...
