View 11 RepliesPossible To Call .exe Files With Shell() Or Process.Start()?
Aug 8, 2011I have an issue in my project I 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.

C# - Detect If Application Start Using A Manual Handling (Pressing An Icon) Or Start When Windows Start?
Feb 28, 2011I 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)?

View 7 RepliesCalculating Value And Showing Answer In Label?
Jan 24, 2012I have several buttons in my form and they each need to add, subtract, divide and multiply certain values together but I seem to be having problems with this. I didn't expect anything to go wrong and its probably a rookie mistake, but take my first calculation for example; a user must enter a value in a textbox (txtDays) and and also when one of my various radio buttons are pressed a value shows in a label (lblDailyHireCharge). I now need a way of multiplying these values to give me my answer shown in a label. I have done this by adding a button when which pressed multiplies the txtDays value with the lblDailyHireCharge and then shows it in the label, however it keeps on showing "0" when i click it.
Below is my code, I am basically saying that the value of both of those figures is intDuration and that lblDuration is where I want it to go when the button is clicked.
Private Sub btnDuration_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDuration.Click
Dim intdays As Integer
Dim intDailyHireCharge As Integer
Dim intDuration As Integer

Mar 19, 2009I'm trying to make a quiz application with Visual Basic at the moment. I want to write a routine that asks five questions to which the answer must be either Yes or No. It must add up the number of Nos and if the number of Ns is less than two then print out "pessimist", otherwise print out "optimist". So far this is the design of what I've done. [URL]. However, I have no code which I've produced on my own.
Code:

End Sub
End Class
I really don't know how I can kind of add up all the results from each individual question, seeing as radio buttons are used.
Sql :: There Are Fewer Columns In The INSERT Isn't The Answer?
Jun 30, 2010I have an application that converts one database to another and one of the functions I use is insert_Note below. This application has multipule threads all inserting diffrent data into the new database. The code below works for a number of inserts ranging between 24 and 120 but then fails with the error:There are fewer columns in the INSERT statement than values specified in the VALUES clause. The number of values in the VALUES clause must match the number of columns specified in the INSERT statement.I you look at the code you will see that this cannot be the problem as the code works for some inserts but not all. What else can cause this error in a multithread applicationuld be welcome as I have spent three days on this and got no where!

Jul 24, 2011I 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.
