Is there any way to get this code to constantly refresh in the background to post the latest text located in the "OppScore.text file in the textbox?
Dim OppScore As New Net.WebClient
Label4.Text = OppScore.DownloadString("(source URL)/OppScore.txt")
I need to parse a Unix text file so, I am using System.Net.WebClient to ftp into a Unix server then using the .DownloadFile() method to get the text file, but its coming in with the Unix end line ""; so is there a way to convert that to windows format while doing the DownloadFile method? I do re-read it after and fix it, I am just looking for a better way.
Or is there an alternate such as instead of a DownloadFile, and the two other steps above can I just read it into an array right off the Unix server?? If so then what method would I use?
I'm making a calculator for a finance company, it keeps track of how much money,bills, and all the totals of everything, and how much your budget is and so on.I have to have it run automatically, by that I mean no buttons at all. When a user enters a new bill or new payment, I want all the totals to reflect the change, say if I add a new bill, my budget will decrease, and so will how much money I currently have.Here is an example I've made up to show what I've done:In this sample, I have one textbox named TxtTotal, it populates all of the payments you have received, in this case up to 5 payments. I'm kind of confused on how to currectly refresh all the data. Right now I have this timer that will refresh the application every 6sec. Thats currently my problem, how do I get the this textbox to populate all the data on its own without using a button.

View 9 RepliesI have created several small applications that use my own DLL. The problem is, this DLL is constantly changing. My current solution to this problem is that I have a Setup project in the class library solution that creates and registers the DLL. In all my applications I then have to open the solution and re-reference the newly created/registered DLL. Then I have to re-compile their setup projects, uninstall the old applications, and then re-install the new application.
There has to be a better way and I'm just not sure because I'm fairly new to all this. I have looked into ClickOnce but I don't think that will solve my issue as I cannot publish a class library. I have looked into checking version numbers but I must be doing something wrong because it doesn't work either.I understand that once a DLL is created and being used in an application it should essentially not be touched. I do not have that option in this situation. It is constantly updated. Done.
Edit: The DLL is not constantly changing during runtime but it is constantly evolving to allow more functionality and detail within the other applications. Also, one big thing I guess I should have mentioned is the Public interface is constantly chaning - usually adding new methods.
How would one receive a value from a function while it is running?
View 2 RepliesI am working on a project that reads in data from a device. I am able to read in the constantly changing data only, i need to be able to read in the saved data that is in the device as well.
My question is if the data that is saved in a certain type and i only read try to read it in as text for example, will the saved data I am looking for not be displayed?
ex: im trying to read in text but my device has the data saved in hex, do i see anything or nothing?

I have a simple translating program i working on in vb 2010.I have a combobox and a textbox and a button. What i have so far is when you select the option in the combobox the textbox and button will appear. then when you type something it replaces each letter with something new, in the same textbox.what i cant figure out is how to make it so where if i click the button again it translates the replaced letters back to the original ones.

I have built a web browser and my new window function is working great, it allows me to open popups that use normal https links without a hassle. But I am having some problems when the links contain java code (like the one below:
("javascript:var%20x=window.open('https://auth.det.nsw.edu.au/pls/orasso/orasso.wwsso_app_admin.fapp_process_login?p_app_id=F0CB644DAE48EDE00D83EFE378FD435E','My_Staff_Email','menu=no,toolbar=no,resizable=yes,scrollbars=yes,status=yes')"
The reason why this operation fails because the string that is being passed to the Navigate method is not an actual URL.It is apiece of Javascript code which needs Javascript engine to process it firstly. Apparently, Webbrowser.Navigate() does not have this functionality,so it fails. If you simply put the string in IE�s address bar and press enter, IE will also not able to open it. The reason why it does work if you access the HTML page in IE and click the hype link is because this will make IE to use Javascript engine to process the code.
Since the API(Webbrowser.Navigate) does not have the functionality to process Javascript code,build up my own code to process the string which you get by using the GetAttribute method. The code reads the string and finds the actual URL and passes it to the Navigate method.
The only problem is that the javascript code constantly changes (varies upon what link is opening) and the url itself will change depending on what the link is linking to! Below is the code that I use at the moment to get the full link .finding the actual URL in the javascript even with the javascript differing from link to link).
Dim myElement As HtmlElement = CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).Document.ActiveElement
Dim address As String = myElement.GetAttribute("href")

This is an annoying issue that started less than a week ago and couldn't come at a worse time, as I have a major project deadline to meet. At least once every TEN minutes, the program crashes with the error "Microsoft Visual Studio has stopped working" -- it only occurs when I am writing/editing code while execution is paused (Edit and Continue), which I do all the time since I am stepping through rather complex subroutines line-by-line. I literally have trained myself to save after each line of code I write, delete, or change, so thankfully I never lose much, if anything, when I restart, but it is irritating and time-consuming having to set up everything in the program and get to the place in the code that I was before. I have installed VS 2010 SP1, tried deleting the .suo file, and a few other supposed fixes that I came across online, to no avail.[code]...

I am using creating a server/client style program, and it uses tcp connections.Now, the server is like this, but it will only listen until it has received its one request. My issue lies in the fact that it only listens till it receives the one message, then closes. The bigger issue, though, is the lag, it will not let me interact with the form in any way until it closes the connection. Is there a way to make it "passively" listen, for lack of a better word? I do not want it to take up tons of cpu.

View 2 RepliesI was getting some slightly unusual behavior when using the mouse wheel for some zooming/scaling work (only vaguely related to the earlier thread, for those who remember it). Frankly, it is likely that I have a bug in some code, but that wasn't quite enough to explain what I was seeing. Therefore, I used a error logging feature in my app to note the delta being passed in each Mouse Wheel event. I then ran the app and gave the wheel one good spin, which was about the maximum that I would normally ever spin the wheel in one steady, continuous motion. I wasn't going slow, I wasn't going fast, and I rotated it about as much as my finger comfortably could in a single roll.[code]I then rolled it back the other way using the same motion, and got 8 events, mostly under 200, but one of them was -331 and the other was -7940.
After a handful of tests, it appears that the wheel event is raised often, which is no surprise, but that the values fluctuate all over the place. With a continuous rotation, or as nearly continuous as I can make it, I can see a series of events with one of them easily being ten times the rest.The problem this presents is that the scaling I am using is not smooth (nor is it standard mathematical scaling, but that's a different story). Each zoom level doubles the size of the objects relative to the previous level, though the distance between them stays the same. I would like to do this by dividing the delta by some factor, and if that is above a threshold, increase the zoom level. That won't work smoothly, in this case. If I make the factor something small enough that I pick up a small rotation, then any larger rotation is likely to include a delta that takes the screen through all zoom levels in a single step. Alternatively, if I make the factor large, then all smaller rotations are simply ignored.One option would be to filter out rotation values below 200 and above 800, or so. I am looking for other alternatives.

View 4 RepliesI have a DataTable that's constantly being updated with new data from my database via a timer. That data is eventually reformatted and displayed in a DataGridView control.In an effort to prevent the DataGridView from completely refreshing from re-databinding (thus, clearing out selections, resetting scrollbars, defaulting sorting settings, and making the gridview flash as it reupdates), I'm simply removing old rows from the datagrid that no longer exist in the DataTable, and adding new rows to the datagrid that appear in the DataTable since the last update.
For the sake of simplicity, we'll call DataGridView the LEFT table, and DataTable the RIGHT table I'm looking for a way to go through both tables (LEFT and RIGHT), and remove old rows that are no longer in RIGHT and delete them from LEFT. And look for new items in RIGHT and add them to LEFT. Each table has a column called "RecID" containing a unique id for each entry that can be used for comparison. is there a way to do this all in one loop? What I'm looking for, in pseudo code:
<loop through everything>
if RecID does not exist in LEFT but exists in RIGHT
add new item to LEFT
if RecID does exist in LEFT but does not exist in RIGHT

I have a windows form where I want the time to constantly be updated. Right now it will take the current time from when the program was started.
For example, if I started the program at 4:30:29 PM that is what it will show the whole time the program runs.I need it to constantly be updated as the seconds tick by. So, If I started the program at 4:30:29 PM and ran it for exactly 5 minutes, the time displayed then should be 4:35:29 PM.The data being taken in and saved needs a time associated with it and the end user also need to know the current time as the program is ran in full-screen.
