I created a form which,through the input of a URL via a textbox, downloads a file from the internet. For example I write in the textbox [URL] and after I hit the download button the software starts downloading the file (the progress is shown via a progress bar). What about if I want to stop the download before the download is over? How can I do it? What should I write in the "Stop" button?
View 6 RepliesI have a program that everytime it is started download a file, read to a list, and add an entry to that list.That entry will be the useres ip address. I have gotten that far so far, but the ip address is sometimes the ip address of the lan like 192.168.1.100. That will nto work properly. I want the true ip address like 69.47.192.12

I am writing a program that will stop the download prompt in the IE control. I have an program that has a browser. I want to fix the browser that way it would stop the download prompt from showing, and stop automatic/manual downloads. I already tried a list of file extensions, then check the URL of the browser for the file extension.

View 17 RepliesAlright, so I'm still working on the slot machine. I have three timers all independently going for my three "wheels" of the slot machine.
My issue, is that I'm trying to make a Stop button to stop each timer one at a time, and I'm not understanding why this code isn't working. The logic completely makes sense, and the first "wheel" stops when I click the button, however, it doesnt appear to stop the other two timers.

I have a simple application that use thread pool to read a file and input the data into a listbox. I want to be able to stop threadpool from running after clicking a stop button. How do I stop threadpool? Here is the code for my application below:

I created a form and have the variable inputs for 4 motor run statements. Then with a start button the script starts and it is surrounded by a for next statement to loop 10 times. It works fine but if i need to stop the execution of the script with a stop button. I put the stop in a new section but of course does not work to do a motor stop. It just causes the exe to not respond till the loop is complete. Just need to be able to stop the Run1_Click button section.
Edit:I do not mind if it finishes the 4 motor run commands and then stops execution of the loop. So need to figure out a way to trigger a stop from a button on the form to stop the cycle. For the future the loop will be a variable integer input so 10 will not be the standard.
Edit::Does a ' Do ' statement sound like the thing to use? If so how and where would I place that? Have a Stop button on the form and it would stop after the 4th motor run command.

I have a START and STOP button and when the user clicks "start" the program does a whole bunch of calculations and all. However, I noticed that when I was testing the program I clicked STOP the program continues to execute stuff.
My START code is basically a while loop that iteratively does some calculations.
So I just put a boolean variable as the while condition and when user clicks stop its set to false and when user clicks start its set to true. However, when I click stop, the condition is set to false yes but it still executes all the code until the condition is re-evaluated right...so my question is how can I get out of the while loop when user instantly clicks "stop"?

This code is in VB6, but I am not sure how to even start using it?
Waaaaay back in 2003 I took a course called "Programming with the Microsoft .NET Framework (Microsoft Visual Basic .NET)" Then I attempted for the next year to get approval to take more courses, failed, and eventually gave up. Now, I'm being asked to write applications using VS 2008. I have, of course, forgotten everything I learned 6+ years ago, plus I'm sure things have changed. Plus we still don't have money for me to take any courses. my question to you is: can you recommend a free website, or a book I might find in my local library, that will give me a kick start into writing VB windows applications (database driven) and/or ASP.NET applications (also very database driven). I'm proficient in VB 3, 5, and 6, along with ASP classic using VBScript.... I just have forgotten pretty much everything I once might have known about .NET.
View 6 Repliesim new to this forum and to VB.NET, however over the next year I think I won't be getting a placement so I want to get as much programming experience as possible. I would basically like to learn VB.NET. Does anyone know a good site to explain its concepts and a compiler for it, which is compatible with a MAC.
Im sorry if you think this is a waste of space for asking but I'd rather download something recommended by people who frequently use VB.NET.
btw any tutorials out there on how to create database with vb.net with mssql just to let me get started, i was hoping for a simple db to practice on like id,name. ive made db with php and mysql but vb.net is a bit far from php and mysql though the concept is the same..

View 4 RepliesI want to know if there is a way to get each new process (what has been started) in a real-time manner (instantly). I tried until now something like:
1. Getting the number of opened/running processes
2. If the number is different from the previous check then the program is scanning each process (what is running) using a timer, each process has assigned its "pid" (using array) -- so if there is a new "pid" the process will be scanned -- else the process will be skipped. (scanning: getting its "object" path and creating a md5 signature etc.) This is working but is inefficient(very)...
What control(s) do I need to use and how do I use them? I am ,looking for tutorials and sample code too.

I do a lot of work with HTTP requests from within my applications, like building GET and POST requests and returning strings that are parsed and what not...I was using the winHTTP COM object in vb6 for the longest time, and I loved it... It was structured nicely and when Dimmed "with events" opened up a nice way of implementing progressbars, calculating download speeds, etc etc...
1) What is the .NET alternative of the winHTTP COM Object...
2) How do you dim objects withevents globally across a form class?
In vb6 I would dim my winHTTP object at the top of the form with events, and then I could implement all my progress bar code in the winhttp events that are exposed....Also then in each subroutine you then have to set = new winhttp.winhttprequest to create the new object, blah blah blah...
