User Defined Directories - Code - "Project Processing' Section Doesn't Run At All?
May 28, 2009
I am having trouble with this code. Can someone tell me why the "Project Processing' section doesn't run at all? The 'Client Processing' section runs and executes find but it seems the 'Project Processing' section does not.
Code:
Public Sub btnExecute_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExecute.Click Dim mBaseFolder As String Dim mProjectFolder As String Dim mClientName As String Dim sClientFolder As String Dim sProjectFolder As String

I'm looking for a little help; I've tried everything. Here is a little section of code of a bigger project. What do I need to plug into the ? in the FillRectangleRectangle call to get this to work? I got the FillRect... example from MSDN, but I can't figure out how to call it correctly.
Private Sub PictureBox1_Click(sender As System.Object, e As System.EventArgs) Handles PictureBox1.Click Dim i As Integer Dim pt As Point Label1.Text = "=" & MousePosition.X & " Y=" & MousePosition.Y & " "pt = New Point(MousePosition.X, MousePosition.Y) For i = 0 To 117 If rects(i).Contains(pt) Then Beep()FillRectangleRectangle(?, i) End If Next i End Sub Public Sub FillRectangleRectangle(e As System.Windows.Forms.PaintEventArgs, ByVal i As Integer)Dim blueBrush As New SolidBrush(Color.Blue) e.Graphics.FillRectangle(blueBrush, rects(i))End Sub

I am having very odd behaviour from my compiler when i run my program, i have two practically identical snippets of code that are doing pretty much the same thing: both are populating nodes on a treeview using information from the treenode above but when the program runs one of the snippets tells me at runtime that something i have defined is nothing. [code] section and title are columns in a dataset defined by dtName that exists, and the where bit is refering to a column where the entries match the value assigned to volume. which is 1 in the first iteration.

It looks to me like a reference error yet all Crystal reference are included. I have set up a test program and this work fine. Yet when I run this in my main program I get this error. This is trying to run a Crystal Report. I know this is Crystal but I don't think it is an error or issue with Crystal I think it is more related to the the set up of the program.

I have an application that has a timer. Every hour, the application will see what time it is. If it is after 5 P.M., then the application will shut the computer off. (For power saving purposes)I have a messagebox pop up warning the user. I want the user to be able to hit "Cancel" on a dialog box if he/she is still working on the computer and reset the timer to ask again in about an hour. If the user isn't there to select a button on the messagebox, I want the computer to turn itself off. But I can't get the code to skip the dialog box after so many seconds. [Code]

I have a window service that Inherits System.ServiceProcess.ServiceBase. While running in debug mode (havent tested compiled), the thread does not see the current user credentials. I need the credentials so I can set up the WebProxy and I would prefer to use the account that service is running under instead of passing the user and pwd as a string.Can someone help me figure out why the code running in the class the inherits from ServiceBase does not have have the credentials of the logged in user?

I found out how to get the emulator working for my kinectmultipoint on 32-bit and 64-bit machines (i still need to confirm 64-bit by tests but 32-bit works). I used the webbrowser controls invokescript property and placed my vbscript code in an html page to tell internet explorer engine to pass script to correct version scripting engine when executing the vbscript.
after using navigate property I use these lines of code:
In form load: 'setup the softehci controller before executing dsf code!
Shell("C:Program Filesdsfsoftehcisoftehcicfg /REMOVE")
Shell("C:Program Filesdsfsoftehcisoftehcicfg /REMOVE")
In button1 click event: Webbrowser1.Navigate("path to html file with vbscript")
Webbrowser1.Invokescript("my vbscript method")
Note: i think this approach only works in local mode not on a web server or such.
So if anyone wants to check up on the project or help me i just need to change the vbscript to add multiple mouse devices and then i portion it up to do these three main functions:1. Add a new mouse device when kinect detects another person walking up to computer.

I'm converting a user generated list box to an array and then generating a user defined number of random strings and placing it in a textbox.The code I have works fine as it will generate the number of random strings the user wants, except sometimes a line is blank at the top of the list but is counted as a string.

I'm just starting to learn vb.net and have never worked with cookies. I'm wondering if I can store an array of name value pairs in a cookie, so they can be retrieved by index number. I'm not really even sure if that's the best way to handle the issue. I basically want to have three things: an 'add/delete' page that has a text box for creating new favorites, along with a list of their current favorites, with the ability to individual delete favorites from the list.be able to display their existing favorites from the cookie on a separate page and a button I can put on all my pages for 'add this to favorites'I don't mind doing the research, of course, but really need direction on what will be required. Having never worked with cookies, I don't really know the limitations.

I use a SqlDataAdapter to fill a DataTable and then set that DataTable as the DataSource for a DataGridView. All works well. Then I add a column at the beginning of the DataGridView that will allow a user to check/uncheck a row for further processing. All works well. Then I display this to the user. All works well.
Since there are many times when the DataGridView could be displaying hundreds or maybe thousands of records, I have a button that will "Check All" records and another that will "Clear All" records. These work fine, but I've noticed a serious performance lag. Other test code that I've got shows that in an unbound DataGridView, even a large one with 50+ columns and 5000 rows, checking or unchecking all of these fields takes mere fractions of a second. (One test with 50 columns and 50,000 rows still only takes 0.334 seconds to check all of the rows.)
In my testing (with my current code), checking/unchecking 500 rows takes 15 seconds. Is this because the DataGridView is databound? If so, is there a way to UNbind it (making it simply a stand-alone set of data)? I don't need to push updates back to the server, so there's no danger in removing any databinding. I've even toyed around with this (to make the DGV unbound):

I just learned some basics of multi threading in VB.net recently as I came across processing a large List of records and inserting them into SQL database one by one.
I have code look like this:
Private Sub btnLoadNow_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLoadNow.Click
Dim autoLoad1 As New Thread(AddressOf AutoLoad)
autoLoad1.Start()
[CODE]...
Itemlists is a global lists i retrieved from database, everything looks fine to me but when i run this program, I found that the threads are inserting one records 9 times into the database(I have 9 threads in total), which makes me think that maybe i need to specifically assign 1/9 of a list to each thread? Is there another way to do it which doesn't require the splitting of the list, if not , how do i split it then assign?

I'm having trouble working out how to lock my application out of a section of code while it waits for a response from an external program've used Synclock on a section of code with the Me object in the expression. In this Synclock I call an overridden ShowDialog method of a dialog box, which has a timeout parameter, but does return the value from the underlying ShowDialog function call ,once the timer is setup. Works like this.
SyncLock Me
Dim frmDlgWithTimeout As New frmDlgWithTimeout ' dialog box with overridden ShowDialog '
Dim res As DialogResult = frmDlgWithTimeout.ShowDialog(10 * 1000) ' 10 sec timeout '

I have to select checkboxes besed on group column values. If you see below gridview, column 3 (GroupNo) has 1,1,1,1,2,2,2,2....etc (this column data is not static, will change based on page index. i.e PageIndex =2 may starts with 7,7,7,8,8,8,8,8,9,9,9 etc).In every sectio/Group User must and should select minimun 2 check boxes. so If user select only one check box we need to show a pop up message as " Please select One more check box in that particular section" If User skips the message and move to next section we have to show the same message. We have to force the user to select more than one checkbox in the same section. Mainly our intention is the check boxes whatever user selected in each section/Group belongs to one Category.

2008 Array Processing and Sequential File Processing
View 14 Replies
May 19, 2011
Im a college student and this is my first programming class, i am having extremely diffcult time with arrays and sequential file processing. Im not asking for the whole program, just something to get me started and hints along as i progress with it. Please help me get started on my program, its due in 2 days.
Here are the requirements....
1. The program must input any number of individual�s last and first names using two separate textboxes.
2. The array of names must be sorted by the last name using a bubble sort. You must code the sort.
3. The program must be able to recall the names from the file and add to the existing list of names so that more names can be added to, sorted, and written back to the file in sorted order.
4. Sort in ascending order: A to Z
5. All names must be displayed in a listbox in sorted order when the user wishes to see them.
6. In the listbox the last and first names must be separated by a comma and a space. Example: Smith, Mary
7. The user must be able to search for a name in the array, using the binary search algorithm. You must code the search.
8. Do not use module-level variables. Instead you may choose to use Static.
9. The program must be designed using Visual Basic 2008

I've written a VB.NET program for a client that stores all of its data in XML files. I use the XMLReader to read the data into a dataset. When I run the sub to encrypt the XML file, I'll get the following message: Error: mscorlib: The requested operation cannot be performed on a file with a user-mapped section open.
It doesn't happen all the time, so I know it does work. But on occassion, I'll get this message. I've been all over the forums and I've tried everything I've read to try and stop this error.
I close the reader object and set it equal to Nothing. I've even tried using DoEvents to make sure the object finished closing before running the Encrypt sub. Nothing has helped.
I develop on a x32 PC. It works fine on the development machine. But then, when the client runs it on a x64 PC, he gets these errors. Could the x64 system really be running so fast that the .Close() and the = Nothing and evern the .DoEvents() can't keep up?

The above code reads all the files & directories in a selected path. It ignores any hidden folders, like it suppose to. Except it doesn't ignore folders inside of the hidden folders that it finds & I need it to.I can't quite wrap my head around how to make it ignore all folders & files inside of a hidden folder that it find.

I've discovered a problem that's fairly huge in my work environment and unusual. I'd say that it's impossible for it to be happening except that it is happening.
You have a window (we'll call it window 1) open with a page in it, you enter some data on the form, push the button to submit the data...behind the scenes a decent amount of work is going on.While data is processing in window 1 , you open window 2 and try to load the same page that is processing data in window 1.Window 2 will not render the page until window 1 is done doing whatever it's doing behind the scenes and has re-rendered on the screen.This is happening for all .NET pages in our environment.

example of a user-defined exception in VB.Net. I already have two examples that I was able to find online, but other than that, I cannot think of any more. I need to find at least 5 to put in my notes, and then submit to my teacher.The two I have so far are: invalid login information (such as improper username or password), and expired credit card information on an online store.

I'm a new user of VB.Net. I do have doubt on accessing a user defined Function or Sub. In some place of program, I do see the term "Call" when using the Function/Sub. In some other place without "Call". But both works perfectly. May I know the difference between the two.
