I'm trying to write a program using Internet Transfer Controls, but I'm using Visual Studio (Visual Basic Express) 2010.
Is Internet Transfer Control omitted from the express version?
I am getting an error 12002, which is Request Timeout.I would like to know what its default timeout is.
View 1 RepliesI've been working on my game for a while, in a non-online multi-player state it is complete. My goal is to add LAN or Internet Play support.My game is coded in Microsoft Visual Basic 2010 Express, It relies heavily on timers.Currently you play against the AI, and there is a Local multiplayer mode, using mice, controllers or the keyboard.At the moment, it is a two player, (Or 1 player against the AI) game, from my understanding the standard Client-to-Server option wouldn't very efficent, the best choice would be a peer-to-peer system.That being said, a lot of the stuff could be done client side, like for instance, the particle engine and Dynamic Rendering.[code]
View 1 RepliesI 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.
[code]...
1. How much load or data size our custom encryption/decryption algorithm can handle? E.g. what's the limit of file size that normal encryption/decryption algorithm supports.
2. What's the best way to use encryption while file transfer via internet?
3. Where and when encryption and decryption has to apply while uploading and downloading content from internet(Hosting on client or server machines)?
4. What type of algorithms suites for above approaches?
5. How much time it takes to encrypt / decrypt data for 10 MB, 100 MB, 1 GB etc
I have used the following code to get bandwidthIt works but i have following doubts1.I need Total Internet Data transferred in MB, how do i convert?, total data transferred (download+upload) varies with other bandwidth monitoring applications. how do i get exact data transferred?2.I need to exclude file transfer in local LAN in Data Transfer, The follwoing method includes internet data transfer + Local file transfer

View 2 RepliesI have some questions about the Windows.Forms.WebBrowser control.I have added this control to my project to be able to browse websites internally.First problem is that when I come into a webpage that contains JavaScript to open a new window, the control opens a new instance of iexplore.exe, tries to load the page in which the java script popup code initiated, but then prompts for authentication for a second time.Basically, I have to sign into one page to get to a listing of applications.I click on the application which in turn is just a URL to another page.The URL to the other page contains java script to open a new window.The new window opens in an iexplore.exe process, but re-directs me to the original sign in window instead of taking me to the correct site.If I do a msgbox on the cookie that is currently loaded, it displays my authentication information.How do I tell the new iexplore.exe processes to use the cookie that was stored in the webbrowser control?

All tutorials in the wild are making me more frustrated, since the snippets I use, in most cases, are different classes.What should I use? HttpWebRequest/HttpWebResponse or FileWebRequest/FileWebResponse?How do I save the ResponseStream to a file ?Is it possible to use ResponseStream to define the kind of File (FileInfo) Class to get basic file information (size, extension, etc) is it generally neccessary, if GetResponse().headers gives you most of this info ?
My code, which sucks, because I do not know how to realize the saving....

I am trying to make a user account SQL database work with Visual Basic 2008 Express for login purposes, i.e. usernames & passwords. Plan is to host this server so people can login to use the the application and verify they have a valid account. I would like to host all the account information in SQL due to the possiblity of hundreds of users at any given time. I also need the ability to add data to the database for users registering for the first time. The SQL server will need to be able to access the SQL Server databases remote via WAN.

I tried to start using VB 2010 Express with a program I originally developed with VB 2005 Express that I moved to VB 2008 Express successfully a couple years ago. It uses a database file (*.mdf) that is on the computer ( not out on a server). When attempt to run the program in debug mode, I get the following error "An attempt to attach an auto-named database for file C:Documents and SettingsTomMy DocumentsQuizzing StuffQuestion Database 2010QuizQuest ionGameQuizQuestionGameinReleaseQuizQuestionDB.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share."
I first made a copy of the entire project folder that was working in VB 2008 Express and gave it a different name. In VB2010 I opened the project in the copied folder and it said it successfully converted the project. I am able to open the Data Source inthe Designer and see the database structure as I expect. I think the project is still using SQL Server 2005 Express (because it is what is checked in the list of prerequisites on the Publish tab).
Note, I have programmed off and on for many years, but fairly new to using databases and SQL Server.

View 1 RepliesI am trying to re write a VB6 program using MS Access, many years ago, using VB 2010 express and SQL server 2008 R2 Express. I have a database with several tables, which I created using the designer. I am able to connect to the database and select data and display it in textboxes etc in vb code. What I have not been able to in code is to INSERT rows DELETE rows or UPDATE any data in the tables. I can do any of these operations using the Query Designer, but I want to do it in code. I can post some code if necessiary, but I thought it might just be some property that I had not set in the designer.

View 7 RepliesInitially my app worked with excel fine, now it causes my computer to reboot only after Excel has been opened (two or more times). I have opened and closed Excel files 20+ times without running thru either of my apps (they all uses identical code for excel) and it has never caused a reboot or a crash.
run either of my apps and have the app control excel has become a crap shoot, it will reboot my computer. Adding to that I then have to do a manual shutdown because the reboot process after is unstable. (System doesn't respond properly). My code in this app is small, should make for a good example. I can provide the entire project to anyone who would volunteer to test it. (First I need to know how to send the project).
