View 2 RepliesVS 2010 Getting Started With Linq, Code Is Very Slow?
Oct 19, 2011I am using DataSet.ReadXml() to create a DataSet from the following XML file, so that I can quickly query it using Linq.[URL]..I then use the following object to create a DataTable which can be used as a dictionary, with a ConvertToFriendlyFormat function that takes an Emulator_Id and and a string that corresponds to a DicEntry node's StoredFormat attributed, and return the same node's FriendlyFormat attribute.
This does work BUT it is extremely slow (~11 seconds to call it ~220 times). I have been unable to figure out how create the DataSet when the object is initialised and just query the simple DataTable in the ConvertToFriendlyFormat call. I guess this is what is slowing it down?

Once The Timer Has Been Stopped And Started, Code Does Not Goto The Elseif Part (i.e. I=5)?
Jul 19, 2010i was trying to make a free microsoft word plugin in vb.net. It automatically fills a web form. The main problem with the plugin is that it uses web browser control and once it has filled a form it will need to navigate another form. The form can only be filled once it has completely been loaded.so my approach is
1. navigate to first site when form loads
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
WebBrowser1.Navigate("http://google.com")
End Sub
2. use an integer i and use if statements to check which form to fill :
Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEv entArgs) Handles WebBrowser1.DocumentCompleted
If (i = 1) Then[code].....
3. this is the main step. you see when main form loads, i=1 so browser goes to google.com (first form), when form is completely loaded, itchecks for value of i. Since i=1, it fills google. After filling and continuing i=2 and browser goes to my personal account page. This means browser again loads the document. Now i=2, so it fills my personal detalis. Now the timer starts. Since i=3, browser navigates to second site and fills the details.
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If (i = 3) Then
WebBrowser1.Navigate("http://blogger.com")[code]...
now the problem arises. The browser does not go to the third site. Once the timer has been stopped and started, the following code does not goto the elseif part (i.e. i=5) why is that so?
Reading Someone Else's Code?
Jun 10, 2011What are some practical ways to resolve legacy code in an n-tier architecture where all of the code is written in self-referencing web services? So far, much of the code is undocumented, uses old VB6 conventions, and there are very long procedures. What's the best way to approach, let's say, a change of business rules for such a large project without having reliable documentation?
I have limited access to the original developer of the code. How can I better document the process and complete my assignments, knowing that the code is changing daily and there are several dependencies for each method, there may be xml files, sql queries, and other unconventional resources being accessed.

Designing The Flow Of Code When Reading / Writing From Database
Aug 8, 2009So I'm trying out a concept tool of mine where I need to be able to read and write data from a database real easy. I've set up the form as I like and spread around different text boxes and dropdownboxes to read the data from the database. And I've got it all to work and all, but there's a small bug I don't fully understand why's there. Some textboxes don't update the text from the database.
But it seems as it only occurs if the data in the database is nothing. So the value from the last row is still hanging in the textbox and thus, clicking "Update" actually updates the value from the field from the last row, into the new row. Messing everything up.

View 1 RepliesGetting Started All Over Again?
Jan 4, 2010Waaaaay 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.

Mar 6, 2010I 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)...

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...

Type: Orthographic
X: 70°
Y: 10°
Z: 20°
somehow turns this -> into this -> and
Type: Isometric
X: 314.7°
Y: 35.4°

I have other information, like the coordinates of where the picture appears on a canvas, it's width/height, etc. if that information is useful too.

The program also has a GUI.I want it so that when the user clicks the desktop icon, it does not start a second instance of the executable, but instead reveals the currently running background process. Is that possible?i.e. when the application is started with the "-startup" paremeter, it loads a hidden form2, and closes form1. When the desktop icon is clicked, it loads form1, while form2 remains hidden.
