Find Out Number Of Occurrences Of An Item In Array?
Jan 17, 2012I'm using Streamwriter/Streamreader for the first time in this project and keep getting an "Argument out of Range Exception was unhandled" error.It says "length cannot be less than zero. Parameter name: length."This happens at "dblYearly Income." Also, how do I find out the number of occurrences of an item in an array? For instance, I have a Race combobox and need to find out how many occurrences there are for each race.Also, is there a way to count the number of occurrences of an array itself, I guess the upper index value?

View 7 RepliesFind A File Without Knowing Where It Is On All Drives?
Aug 3, 2010SPECS: Visual Basic 2008 - SP1/2, Framework 3.0.3.5, Windows XP Pro, SP3? trying to wright code for checking for existing files but what has me stumped is the (WHAT IF PART) of it witch in fact is what I want to see. What im saying is can I find a file without knowing where it is on all drives? Or how can i find a folder if I dont know where they installed it to.
Example: I know that C:Perfect World International <--- is the default location where my game installs but what if I installed it on D:Perfect World International; or rather on drive G or H. How would I test to see if it exist without making a bunch of nested If statements to test every drive for it.
this also applies to files like: D:Perfect World EntertainmentPerfect World Internationalelementelementclient.exe is there a way to find these files to see if they exist. I know that Perfect world international does not use the program files to put there program files in as you see above. so Envirnment variables I think cant be used correct me if I'm wrong. BUT I know the registry of a computer keeps some stord information as to where these applications are installed to like (References App Data).
What I'm trying to do is use this to tell the user in a Label that the game is installed in this path but I know in some circumstances the game is not installed on drive C: or D: or even in this directory some users can install it in there own directory such as C:PWI. and as such the file elementclient.exe can even be in C:PWIelementclient.exe. So to sum it all up can this be found useing some sort of code to find the file and folder and return them both in 2 difrent labels like this
Game Is Installed In: C:Perfect World International
Game Client Name: elementclient.exe, C:Perfect World Internationalelement
Game Found On Drive: C:
ETC.
I'm thinking and keep thinking that this can be done in many ways but as for environment variables I'm stumped. But perhaps windows registry may play a role in doing this but I myself don't even know where this stuff may be found; and even more how to apply it to code.
Set ListBox Item Text Without Knowing What Kind Of Object It Is
May 14, 2010I'm creating an editable ListBox control, where the user can double-click an item to edit it. When double-clicked, I simply overlay a TextBox over the item, so the user can change the text and then commit it by pressing Enter or leaving the TextBox. The 'commit' is simply this:[code]where 'editingIndex' is the index of the item being edited, and 'textBox' is the TextBox object.If the ListBox contains strings, this works just fine. The item being edited is replaced by the textbox Text string.However, if the ListBox contains some other object (let's say a custom class), this is a problem! It still "works", in that it still sets the text of the item, but the item is no longer an instance of that custom class! It is now a String, and all other information about the item is lost. So, I really want to let the user be able to change the text representation of ANY object, without replacing the object with a string. Obviously, I cannot know how the object displays its text (well, by the ToString function of course, but I cannot know what the ToString function returns).Now, I am having a few ideas how to approach this, but none really work the way I want. I am pretty sure that I'm going to have to provide some kind of event that the user has to handle. I'm thinking something like this:
- When the item edit is committed, an event is raised
- This event contains the Item being edited (as an object, the user has to cast it himself), and the new text of the item.-
- The user handles this event, and assigns the new text to the correct property.
For the Person class, this could look something like this.My ListBox should raise this event, and assign the new item like this.[code]I think this should work (although I haven't tested it), but there's one problem with this approach:When the items are just strings, the user still needs to implement this event handler, while he shouldn't have to (I can simply assign the new text string to the item). So, if the user is simply using strings, he still needs to do this for every instance of my listbox:[code]So what I'm really looking for is a way so that I can implement the default behavior (for String items), and still allow the user to override this behavior if he is not using strings.I may be overlookihe obvious solution here, but I can't figure it out... Overriding is done when you inherit a class, but the user isn't going to inherit my custom listbox (well he CAN, but he shouldn't have to). He is just going to handle the event. And if he doesn't handle the event, my listbox uses the default implementation.
Deployment :: Reliable Way Of Knowing Number Of Downloads
Jan 20, 2012I eyed VB.NET 2010 Express and created the damn app. It's up and running and it does what it's supposed to do (in v1). Now I'd like to distribute it for free while:
(1). Have a reliable way of knowing (and everybody can check this out) the number of downloads.
(2). The app cannot be passed from one user to another, but has to be downloaded from the reputable biz (there can be more than one biz) that accurately provides the number of downloads.
(3). I can have total control over the app (once it's downloaded by the users), that is if I want to inform the users of updates or whatever, or if I want to add some ad windows to the form I can do it whenever I want and how I please.
How do I do (1) to (3)? What am I supposed to read to do (3)? ADO.NET and ASP.NET? Any shortcut? What's the easiest way of doing it? I'm not sure I'm looking for a career in programming, for now I just want to take this app off my shoulders and go back to daydreaming.

Find Smallest Item In An Integer Array
Dec 1, 2010I have an array called linedistancearray.I am now trying to find the smallest integer in that array and store it another variable called mindistance..The following is my initial idea: I sort the array and then pick the integer with index 0. Array.Sort(linedistancearray)However what I get is the first item being a 0 not the smallest integer value in the array I need. HOWEVER if I choose the index 1 it works.So what I was thinking was a way to remove all 0s in the array. I am not concerned about the order of the items at all all I am looking for is the smallest integer in the array.

How To Get The ID Number Of A Selected Item In Listbox
Dec 13, 2011I am trying to use a listbox to hold categories from one table in a database and by clicking on the categories in the listbox it will display data from another table in the database that is linked to those categories. One table has a field called ID and the other has categoryID and categoryID is linked to ID so it displays the numbers from ID.I am using this:
daSamples.SelectCommand.CommandText = "SELECT * FROM tblSamples WHERE tblSamples.categoryid =" & (lstCategory.SelectedIndex + 1)
daSamples.Fill(dsSamples, "tblSamples")
Currently, however with this if you delete a category from the table with ID in it then it changes the values of the selectedindex in the listbox which messes up the data that gets displayed. How can i change this so instead of using the selectedindex from the listbox, it takes the ID from the selectedindex?
