as seen in picture I have in "TextBox1" some numbers and I would like to have a detailed information on "TextBox2" (marked with red) when I pressed the "Process" button about them. In other words, I want the application to tell me how many numbers in total are inside "TextBox 1" and also to tell me if there are some duplicated numbers if it finds some of course?

2008 Array Processing and Sequential File Processing
View 14 RepliesIm a college student and this is my first programming class, i am having extremely diffcult time with arrays and sequential file processing. Im not asking for the whole program, just something to get me started and hints along as i progress with it. Please help me get started on my program, its due in 2 days.
Here are the requirements....
1. The program must input any number of individual�s last and first names using two separate textboxes.
2. The array of names must be sorted by the last name using a bubble sort. You must code the sort.
3. The program must be able to recall the names from the file and add to the existing list of names so that more names can be added to, sorted, and written back to the file in sorted order.
4. Sort in ascending order: A to Z
5. All names must be displayed in a listbox in sorted order when the user wishes to see them.
6. In the listbox the last and first names must be separated by a comma and a space. Example: Smith, Mary
7. The user must be able to search for a name in the array, using the binary search algorithm. You must code the search.
8. Do not use module-level variables. Instead you may choose to use Static.
9. The program must be designed using Visual Basic 2008

View 17 RepliesAlso, programmatically, how do I get the player to stop playing an audio file?I have my app that upon startup has the wmp. The program does not revolve around the wmp, it's just a nice addition for the user. The user has 2 options to "Hide" the player. 1) "Hide the Audio Player but keep Playing the Audio File" and 2) "Hide the Audio Player AND stop the currently playing Audio File". The first option is easy to code, but for the secoond option, I have not been able to figure out in code hoow to "Stop" the audio. And I could not find any examps. Thus, the reason I am asking here.

I'm trying to search for a specific text inside of a textbox.If the text is found, I want all lines above to be deleted.

How do i make it works?
I've been struggling with something I imagined would be simple. My aim is to create a TextBox or Label with in a GroupBox using VB.net, yes I could use the Toolbox/Common Controls to do this easily, but it's a pain when planning on making more than just one or two of them
Here's my current coding to create the actual text box.
[Code]...
All that works perfectly, but how would I allow it to show up within a GroupBox?
my problem is how do i parse or get the text inside the tag ex. <c1>a</c1> <c2>b</c2> from web response and put it into the textbox?
View 7 Repliesbest way to check if a textbox has only 4 numbers and isNumeric, for example i need to enter postcodes.I currently have:
If CDbl(txtPostcode.Text) <> 4 Or Not IsNumeric(txtPostcode) Then
MessageBox.Show("Postcode must be 4 Digits", "Error")
But the message box comes up regardless of whether there is 4 numbers, letters, or anything in the textbox. Its also used in the leave function of the textbox.
I'm trying to open a text file that was already generated with info inside.I want to read specific lines and have them changed via user input.the lines are not consistently on the same "line".An example of the text I'm trying to read and change is:
// General (upgradeable) values the Player sees for each system
hullLevel = 1700
weaponsLevel = 1450
[code]....
The "H" in hullLevel shows up in line 26 in some of the files, line 27 in other, line 36 in some others and line 37 in yet others.
The reason this jumps around is that this comes from a file that is edited by other modders when they create a ship for a game that I'm modding.My program is designed to allow the user to visually see a representation of how strong and well equiped a ship is and change the values of each line with a slider bar.I have all the slider bar and progress bar code worked out.
I just need a way to reliably pull these lines no matter where they are from the ship file chosen by the user so that the program can edit them without disturbing the rest of the text in the file.
Is there an easy way of trapping the enter key in a textbox to process the data, instead of having a button beside it?
View 2 RepliesI have created a User Control (UC) where user type the information it needed and save it ti MS SQL Database and also have created a User Control dedicated for it's button, since my main form has split container and has two panels, one for UC which contain the button only and the other one for my Main UC where user enter the information.I created a Module that contain the function on adding the data type in UC Main to the database.

I just learned some basics of multi threading in VB.net recently as I came across processing a large List of records and inserting them into SQL database one by one.

Itemlists is a global lists i retrieved from database, everything looks fine to me but when i run this program, I found that the threads are inserting one records 9 times into the database(I have 9 threads in total), which makes me think that maybe i need to specifically assign 1/9 of a list to each thread? Is there another way to do it which doesn't require the splitting of the list, if not , how do i split it then assign?
