View 7 RepliesIm creating a quiz game although i was wondering if any one can teach/tell me how to create a high score system.For example when the user clicks say button1 (which is stop quiz) an input box will appear asking the user to input their name and then press okay. It then gets the current score from the text box (which is just an integer in a text box indicating how many they got right) and saves it to an Text file or something.and when the user goes back to the main menu, he/she can select "Hall of Fame" which then brings up the highscores (in a new form) of previous users scores.
View 10 RepliesI just finished making a Tetris game in VB.NET, and I wanted to add a high score system to the application. So, when a user completes their game, they have the option of submitting it as a high score, which will compare their score against the previous high scores, then place it accordingly. I was thinking of an XML approach of doing this, where the user's name, rank, score, level, and number of lines cleared will be stored in tags. Here is what I thought the XML might resemble:
[Code]...
So the program will have an array to store all the previous scores. It will read through the XML, and copy the the score data into this array. Then, when the time comes to submit a score, it will compare this score against those previous scores, and find the proper position for that score, and then save it into the array. At the end, it will then copy all the score data from this array to the XML, replacing the <Level>, <Lines>, and <User> tags in the process.I am however having trouble implementing this, as I have no experience with XML files and everything I've read has been very confusing.
Program : my game is a frogger port, you make the frog cross the road until you run out of lives. When you die, you are asked to enter your name and the name is appended to the end of file called names.txt, the final score is appended to the end of a file called scores.txt.Using the System.IO functions, i read the contents of each text file, and load the contents into two separate strings (one for names, one for scores. These two long strings are then broken down using Split() command, transferring the pieces into an array. (again 2 arrays - one for names, one for scores). The contents of both arrays are then loaded into 2 listboxes, 1 for scores, 1 for names.
Problem: i can sucessfully load the contents of both files, and display them side by side - but i want to re-arrange the scores so that they are in descending order. While doing this, i need to make sure that the player name matches up with the score - so the order of the names being displayed would have to be changed aswell. After spending many, many hours trying to do it myself i have had to give up - i'm clueless. My first issue is converting the score array into integers so that the array could be sorted, the second problem is then sorting the names so that the scores and names match up.
I currently have a who wants to be a millionaire game that I have made in visual basic 2010. Each question is in its own form. Form1 opens at the start, and question 1 is opened by a button click on Form1. The user has to click on the picture box at the side to show the text for the question each time. If they answer incorrectly, it displays a message box, opens an input box asking for their name, and goes to the form with the high score list, Form17.
Upon opening Form17, I want the scores to load and be displayed in the list box. The high scores are saved in a text file at C: est.txt . Upon clicking menu or end, the high scores are saved to the text file.

I am writing a noughts and crosses game and I want to be able to keep score everytime each character wins a game, I have written a sub routine to handle this but it seems to count up in 5's and 10's??I have used a global variable like this Dim i As Integer = 1 then declaired that variable in my sub like this i += 1 (I thaught that this would just add 1 everytime X won a game)then used the variable i to add the score to the label control that keeps the score for the character X.My question is, am I using the correct syntax (+=) for the variable.

I'm working on a project that calls for high-performance networking with TLS encryption in VB.NET. The stock SSLStream sucks rotten eggs; its 'asynchronous' read/write operations aren't async at all, meaning that they'll operate parallel to each other and to the main thread but that it offers absolutely nothing that resembles async read/read and write/write, which means that reads are totally synchronous to each other and writes are too (only 1 read and only 1 write can be done at a time).
I've done a lot of reading on this failing and it seems like MS has no intention of ever fixing this.Hoping a whole lot not to have to write my own TLS implementation. I've tried the Mentalis open source SSL suite, which will NOT compile. I've tried SocketWrench tools which will not compile under VS 2010 (and whose documentation indicates it's in fact synchronous on its async threads too; can only do 1 async read and 1 async write at a time).
What I want/need is an SSL/TLS implementation that actually works with DotNET that actually allows me to do multiple asynch reads/writes over a TCP/IP transport stream. Anybody have any experience or recommendations on 3rd party toolkits or alternate methods of SSLStream I/O?

View 7 RepliesI've made a computer game in Visual Basic Express 2008 and my only remaining problem is to run a data table to keep a running track of the best score. To do this I've created a datatable form called BestScore.xsd. My first problem here is to recognize that it should will start off with nil values and I need to initialize it to zero. Next I need to update the score. I will need to save the score when I exit the game. (Does VBE automatically save the datatable or there a command here?). When I reopen the game program I want it to find my best score from last time.
View 2 RepliesI have been asked to improve the memory efficiency of an application that is used for high speed data acquisition. After running the VS memory profiler several times and scanning the projects for obvious issues I came to the following conclusion: despite using a fixed size circular buffer for storing acquired sample points, the RAM usage increases relative to the polling period. For example: polling data for one signal at 2 microseconds can use 5 times more memory (private bytes) than when running at 50 microseconds ... even though the buffer size is the same.
The circular buffer is an array of SamplePoint objects. Each of these objects contains an array of Shorts (16 bit) for corresponding data per signal and one date object (8 bytes) for the time stamp. For efficiency, the circular buffer is Redimmed only once every time it begins polling and filled with empty sample points which are then "assigned".
Also, it seems that when we stop and run the application it hogs even more memory each time as though the Redim is not releasing the previous array. My questions boil down to the following: What is most memory efficient way of implementing a circular buffer containing managed objects which have arrays?Also, how and why is memory usage increasing with a fixed size array with different polling speeds? Does the garbage collector not have time? Do local variables get disposed of IMMEDIATELY when a sub or function exits?These are some of the doubts and concerns that I would like to rule out before proceeding.

I'm having some doubts on which communication protocol/platform would be better for my current development. The focus is on communication performance, and while reliability matters, I can handle a some packet loss. UDP sounds like the correct choice, but then the following question came up:
"What would be better, using a UDP socket directly in .NET, or using a UDP socket implemented in unmanaged C++ with a wrapper to .NET?"I'm quite sure that C++ is faster than .NET, and while the communication might be faster, I'm not sure if that performance improvement is not lost with all the C++-to-.NET wrapping?
Some info about the project I'll be using this on:
- The core of the project will be all made in VB.NET.
- There'll be a high packet sending/receiving volume (about 100-200/sec).
- There'll be many clients requesting data to the server.
- Network communication will be over a GB-LAN.
- Data is time sensitive, and some packet loss is accepted.
- Running on .NET 3.5.
I want to make a wallpaper changer because windows high compresses the the image so you see artifacts even if already use a jpeg or even a really high quality png or bmp.
I know what I need to do for all of it I just need to know how to save an image to a jpeg without it being compressed. I have tried using the encoderparamters and getcodecinfo aswell as setting the quality to 100 but I still get a really bad looking image in the end.
Is there a way where I can save an image to a jpeg without getting the crappy image quality like with visual basic?

View 1 RepliesI have several services that use UDP messages to send out XML status information which is displayed in an application with a UDP listener. This works well. Some of our services are installed at a different site. The UDP messaging does not cross over the routers. Therefore, I wrote a TCP-UDP forwarder service that listens for the UDP messages at the remote site, then forwards them via TCP to a partner service in our local office. That partner service then re-sends the messages via UDP so we may monitor them.
My problem is that the method that sends the messages via TCP appears to be dropping a lot of the XML messages. When the service gets a UDP message, it enqueues it in a queue object for processing. The enqueue statement is enclosed in a synclock object. A separate thread dequeues the message using the same synclock object and sends it via TCP. Originally, I had the code written so that the TCP Send method instantiates the TCPClient, opens it, does a GetSteam, sends the message with a BinaryWriter, closes the writer, closes the stream, closes the client.
Next, I updated the code to declare the TCPClient at the module level. The send method checked to see if the TCPClient variable was nothing and, if it was nothing, instantiated it and connected it. If it was already instantiated, I just tried to re-use it. I close the TCPClient when the service runs the OnStop method. This way did not work. I get "The operation is not allowed on non-connected sockets." errors.
What is the best strategy for implementing a TCP sender that works in a high volume environment. I only have four services sending UDP messages that need to be forwarded at this time. I eventually will have many more.
I am trying to make file transfer program in vb.net 2008 for big files eg. 10 GB.i was able to code simple socket program to transfer files with small size by using Sockets but if the file is large then "File.ReadAllBytes(ComboBox1.Text)" command will not work cause it use lot of memory & if the file is really big i.e. 10 GB it give not enough memory error, so i made a loop that sends data in small amounts, but this give me a larger file size with repeated data at end of the file.

I am working on a windows service and I am looking for a better solution to an issue with high CPU usage. The service needs to only 'run' every minute or two to gather some db data and do some light processing. Right now I have it running in a separate thread in the service application using the BackgroundWorker. In that thread, I do a Thread.Sleep(30000) after each db iteration. This has taken care of the CPU issue (obvious) but I am let thinking there is a better way. This works fine, I can still cancel the service without issue etc. however it feels wrong. Blocking that thread seems bad.
That being said, what is the best way to actually do this? I don't want the loop to just constantly run, I only want it to do work on a somewhat regular time frame. Would running this in a timer_elapsed event handler be a better way?
