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

Feb 28, 2011

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)?

Update Listbox During A For Loop?

I have a program which I'm designing to help organize and move some of my music around. I can create a play list and then add music to it, when I do this it copies the mp3 files to a specified folder and also updates a listbox with the content of that folder.

The code works, however when I run it the program locks up until everything has been copied, the listbox goes from blank at the start to suddenly showing the whole list.[code]...

Forms :: ListBox Doesn't Update Contents

Nov 29, 2010

I have a form called 'Bookmarks' that loads a bookmark file that contains a single word on one line. I have put buttons on the form for sorting this list, deleting items and changing the character case to lowercase, uppercase or Sentence Case.Now, deleting and sorting the list works fine, but when I try to change character cases,nothing happens. I started the debugger and found that my case changing code does work, but the listbox doesn't seem to update it's contents.I tried listbox.Update() and listbox.Refresh() but that didn't work either.

Here's my code for 'Set Case':

Private Sub setCase_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles setCase.Click
If bookCase = "default" Then Exit Sub
If bookCase = "lower" Then

ListBox Update As Data Added To Database?

Jan 15, 2012

I have a form where i can enter new product. In that same form i have listbox where i show the current product from the database.

I want to know how to update that listbox as i enter new product into the database so that user can see the current content of the product table.

my code to load the listbox

Try
Dim ds As New DataSet
Dim cmd As New OleDbCommand

[Code].....

To sum it up, what i want is something that will refresh the current display of the listbox so user can see the actual and updated contents of the database.

with the above code, the newly entered product/data can only be seen when the program is closed and reopened again. Which is not very convenient.

VS 2008 Update/change Data In Listbox?

Jan 16, 2012

I cannot figure out how to change the data in a listbox. I'm being driven completely mad by vb.net, finding it very very complicated.

Ok I have two list boxes on a form that contain correlated data i.e. the first item in the first list box corresponds to the first item in the second list box.

Under the two list boxes I have two text boxes for data entry.

For Example :
LstTagDatabaseLoop LstTagDatabaseSource
TxtTagDatabaseLoop TxtTagDatabaseSource

I want to Add Update and Remove items from the list. If the user selects an item, I want the selected item in the other list to change to correspond. I also want the two text boxes to be udpated with the currently selected item.

[Code].....

however this invoked the selectedindexChanged sub umpteen dozen times and while in the end it did actually update the data, its obviously not the right way.

I found ListViews which perhaps is more appropriate but I couldn't get my head around it at all so returned to trying to use these listboxes. Is there a different object I should be using.

I'm finding vb.net to be too complicated for a hack programmer like myself...

.net - Why Does ASP ListBox Take So Long To Render In AJAX Update Panel

Dec 3, 2009

I have a problem when updating the source of an ASP ListBox in an AJAX update panel. When I set the source of the ListBox to a large dataset, I would assume it would take a small amount of time to render due to the number of items. However, when the DataSource is switched at run-time to a smaller set of items, it takes just as long to clear it. If you go from a small set of items to a small set of items this is lightning fast. Maybe I'm doing something wrong. I'm using the Visual Studio 2008 item template for an AJAX 1.0-Enabled ASP.NET 2.0 Web Application. I downloaded that from Microsoft.

Here is my code (Full source zip below):

Default.aspx

.net - Why Cancelling 6 WebRequest Using Task.Start Takes Longer That Thread.Start

Jul 24, 2011

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.

Process.Start To Start An External Command Line Application

Aug 4, 2009

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.
