I am trying to load a text file that lists the rosters for each team.I would like this file to be read at program start and add each player to an array. During the play of the scoreboard I would like to display the player in a label.So far I have this:
Dim intPlayer As Integer = 0
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I am trying to create a sports scoreboard that has a game clock. (I am very much a noob at programming)I seem to have a problem with the game clock, I know I am sorry, another timer thread. (Trust me I read through about 50 of the 77 posts with 'countdown' in them)I have two solutions so far, unfortunately neither one are exactly what I am looking for. I want to have a scoreboard that counts down from a set time in the format of 00:00 and allows me to decrease and increase the time if it differs from the official clock.

I working on a scoreboard application for class that would control a scoreboard like you would see at a football game. My problem is that I'm not sure exactly how to work with timers. I would like a timer to start at either 15 or 12 minutes and count down the quarter. I'd like to be able to pause the timer, have it count up in case I need to add time to the clock.
View 1 RepliesProgram Overview: Quiz Show based on answering questions, with A,B,C,D choice answers. If the player answers correctly he moves up the ladder with prizes. If he answers incorrectly his game ends, asking him for his name so he can be added to the scoreboardif the score is high enough. Program should use mysql database or msaccess database to hold the questions. There should be a section with master options protected by a password in which authorized person can update the question database using buttons.Problem: I will manage easily to implement sql database with buttons to add,remove questions , password will be easy too.
Edit: Everything is on the forms, some coding is done.The problem i am having right now is making scoreboard to work. I want the scoreboard to store 10 best scores ie. prize they won eg. 500 000$ and their name. They should be displayed in a textbox or a listbox in a two column system. Right now i have placed a listbox and a textbox on the scoreboard form and trying things out hoping its going to work.

I am trying to create a log file which I am going to use to populate some controls (DataGridView or Treeview). I am trying to figure out if should use text files or XML files to do so. Effectively the log will highlight multiple phases in a client-side app. The log will be written to at various phases when the project is running. The user will always have the options move on to the next phase or save progress and exit the project. As such, I want the log file to highlight how far the user has progressed throught the various phases AND I want the log to highlight varous information from each phase. Whenever the user starts the project, they will be given the option to load existing log files. So the project will have to read these log files and append them where necessary as the user progresses.
I am not sure what the best way to do this is and below is a rudimentary approach using text files. As you can see, the top of the file would have a summary of all the phases and whether or not the user completed each phase. Next each phase would have a data section highlighting what data was stored along the way. I have used a ":" to denote each section. Then within each section I would obviously need to use a delimeter for all my data. So if Phase1 = True, then I would load all the pertinent data from "Phase1:" into the desired control. Can anyone provide an efficient way of doing this and provide some insight as to whether I should use XML instead. The phases my change during development and I am not sure yet which controls I will be using. Does XML provide more flexibility.
In summary I am looking to create, read/write and append log files and populate controls with the data in varous sections of the log file. Example:
Phase1 = True
Phase2 = True
Phase3 = False
Phase4 = False

I need to write data to a file, preferably in binary format, but I am unaccustomed with the concept. Where's the easiest place to get the basics? I could come here with a specific need, but I'm at the point right now where I am more willing to work within the confines of keeping it simple.
Here's what I know:
1. how to open a new file
2. how to specify the record length
3. how to close the file
Some specific questions:
Does the record length have to be constant throughout the file?
Can I read the nth record without reading the whole file?
I have File Like "Sample.bak" and when I compress it to be "Sample.zip" I lose the file extension inside the zip file I meann when I open the compressed file I find "Sample" without any extension.
I use this code :
Dim name As String = Path.GetFileName(filePath).Replace(".Bak", "")
Dim source() As Byte = System.IO.File.ReadAllBytes(filePath)
Dim compressed() As Byte = ConvertToByteArray(source)
System.IO.File.WriteAllBytes(destination & name & ".Bak" & ".zip", compressed)
Or using this code :
Public Sub cmdCompressFile(ByVal FileName As String)
'Stream object that reads file contents
Dim streamObj As Stream = New StreamReader(FileName).BaseStream

I am working on a VB Console Application that takes an Autocad drawing type DWG and converts it to a PDF using a shell command that calls a third party application. In this case, acmecadconverter.exe from www.dwgtool.com. Then the PDF that is created needs a unique watermark, so I call a second application for that called pdftk.exe from www.accesspdf.com/pdftk/.
Everything works as intended, except when I try file names that contain spaces. The file system object does not tolerate spaces in the drawing file name. For instance, the following command gives me a system.io.filenotfoundexception...

View 7 RepliesWhat my program does is load a file (password list), then progressively reads each line of text in the file whilst writing each line to a new file. After X amount of lines have been written, it should start writing the lines of text to a new document until the initial password list has been split into X amount of password lists. The problem I have is that after hours of tweaking, all I can get it to do is write either blank ocuments, or write all of the lines to only one file. I really need it to be able to split into multiple files, preferably at runtime rather than loading a whole text document into the program in a textbox or array then writing it to new files.Below is the source:

I am trying to create an application that will copy files with a "*.1" extension over to another directory and change the file extension to .tif. The problem is that the *.1 files are located within zip files. Is it possible to copy files out of a zip file without having to extract it? The code I have so far is below. I have only gotten to the point to list all *.zip files found in a specific directory in a listbox. I am really looking to list all *.1 files found within all .zip files in a specific directory. Once they are all listed in the listbox, I will then chose a destination directory, copy them to the destination directory and change the files from a .1 extension to a .TIF extension.
