VS 2008 : ImageList/Memory Errors Suddenly Occur In App?

Apr 16, 2012

The user has been running the app in question for over a year with no issues like this (this is a VB2008 business/database application with an executable 4.6 MB in size). Starting last week, "all of a sudden", the user started getting INTERMITTENT error messages like the following:

Exception has been thrown by the target of an invocation.
Creation of the ImageList handle did not succeed.
Out of memory.
Parameter is not valid.

The last two have been accompanied by the big "red cross" on the form (in the screen shots the user sent me).The fact that the one message mentions "ImageList" and poking around on the Internet for answer on "Parameter not valid" points in the direction of a graphic problem, but nothing has changed in this area for a long time, and the app only uses graphics in a very straightforward way, using images on buttons and menu items, but not doing any in-line graphics methods.

Xml Childnodes Doesn't Seem To Pick Up Attributes

Aug 24, 2011

I was under the impression that a node can be anything at all, be it element, attribute, etc etc.I was looking at trying to iterate through a node list, eg ....

Dim xmlDoc As New Xml.XmlDocument
< main1 test1 = 'any' test2 = 'any2' >


Why does the following return only the elements, and not the attributes:

For Each objnode As Xml.XmlNode In xmlDoc.DocumentElement.ChildNodes

How can I iterate through all nodes, regardless of type, using xpath?

I have written a small program to aide my business and the program works fine. But while compiling the code it shows a lot of warnings like the following."late bound resolution; run time errors may occur""implicit conversion from 'Object' to 'String'." Where am i going wrong. Even though the options strict off removes the warning I want to correct the warnings.

Errors When Calculating - Doesn't Calculate Anything Correctly ?

Sep 9, 2009

I am making this program for a school assignment but it has errors when calculating

Private Sub frmReceipt_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'When this form is loaded, assign the date to the date label & start the timer
lblDate.Text = Date.Now


So if counter finishes, execute the following code

If counter > 4 And km >= 1 And kmcashset = 0 Then 'If there is still kms to calculate 'And kmcashset = 0
kmcashholder = kmcash
km = km / 5


And if I add counter = 0 and km = 0 at the end of that "If counter > 4 And km >= 1 And kmcashset = 0" Then it doesn't calculate anything correctly. I supply it with 9 for Distance and it returns 4 for excessdistance which is correct but returns 7 for excessdistancecharge when it should be 4! When I supply 23 for Distance it returns 18 for excessdistance and 11 for excess distance charge which is correct. (???)

Excessweightcharge calculates correctly.

I think it may be the way I'm implementing it, through the use of AND or maybe it's because it's in timer tick?

-Minimum charge of $5 which covers 10 kgs for the first 5 kms only
-Each kg over 10 kgs incurs a charge of $0.50
-Distances over 5 kms incur an additional charge of $1 per km up to 10 kms
-For deliveries over 10 kms, the extra distance should be rounded up to the nearest 5 kms and charged at $2 for each extra 5 km block.

Packet weighing 9kms travelling 9 kms
Standard charge for first 5 kms ($5.00)
Weight less than 10 kgs so no extra weight charge
Extra distance charge 9 - 5 kms = 4kms x $1 = ($4)
Total delivery charge = $5 plus $4 = $9

[But my program returns 7 for excess distance charge]

Packet weighing 33kgs travelling 23 kms
Standard charge for the first 5 kms ($5)
Excess weight 33 - 10 kgs = 23kgs x $0.50 ($11.50)
Extra distance (23 - 5kms = 18kms):
18kms ( 5 to 10 kms at $1/km) = ($5)
13kms (18-5)/5 = 3 (rounded up) x $2.00 = ($6)
$5 + $6 = $11
Total delivery charge = $5 plus $11.50 plus $11 = $27.50

[My program calculates everything correctly]

VS 2010 - End A Statement - Doesn't Close You Program Properly And Hides Errors

Jan 6, 2012

End A statement which as far as i know doesn't close you program properly and hides errors. Right now i'm being forced to use end because i don't know how else to close my program properly. I'm not sure where my problem is but some of you should be able to fix it. I'm trying to make a game using directx with a game loop. This code is the skeleton of what i'm making.

Public Class Form1
Private ProgRunning As Boolean = True

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Me.Load
Me.Show() 'Make the form appear
Me.Focus() 'Give the form focus


This code runs alright because end is being used but if you rem end out the error which it's hiding comes out. The error is "Object reference not set to an instance of an object." I'm not totally sure but i'm guessing that the error is refering to the form.

Synclock Doesn't Prevent Sharing Errors When Multiple Threads Access Same File

Apr 14, 2010

I am using Synclock to prevent multiple threads from logging text messages to the same file at the same time, but this doesn't seem to work:I get frequent sharing errors on the logfile, within the synclock block.The Synclock is using the variable holding the filename, because it exists all the time and because it is always the same object, whatever class instance or thread I'm in.[code]Despite using Synclock and a Using block around the code, I keep getting this error in the sw.WriteLine(Msg) line:System.IO.IOException: The process cannot access the file '(filename)' because it is being used by another process.Should I use some other type of object than a string to synchronize on?I cannot use a user interface object (button or so) because it is a windows service project.It was written and compiled in Visual Studio 2008, but targeting the 2.0 framework because it has to be able to run on some old Win2000 machines.

VS 2010 IIS Errors Loading Project

Mar 2, 2012

A need came up for me to work on a program that resides on a web server. I can't pull up the code and I get these errors:


In addition, you must run Visual Studio in the context of an administrator account. I have never worked on anything like this before and for right now I would just like to look at the code. I Googled and found this: You can enable these features in the Add/Remove Programs control panel. In there you wiull find a link off on the left labeled something like 'Turn Windows features on or off'. Click that and you'll get a UI for managing the IIS features that are installed.

I looked there and don't have a clue what I should check. I'm on Windows 7. What should my approach be? I don't want to just clicking things in the IIS configuration console. The attachment is what I see.

ASP.NET UpdatePanel Timeout And 500 Errors With Custom Errors?

Sep 23, 2011

I have a .net application that uses customerrors web.config module to display meaningful messages for errors. It works without any issues for 500 errors/exceptions caused by non-ajax and ajax components (updatepanel). However, in a scenario where updatepanel's asynchronous request times out, there is no error raised at all. I was able to see the timeout in firebug and come up with a solution that would at least display the error message as an alert and then redirect the user to the 500 error page using javascript but it's not quite doing what the rest of the application does in case of an unhandled errors like these. I basically just want everything to go through "LogEvent" mechanism so based on the severity of the error, it does the necessary work.This 500 error page doesn't have anything in the Server.GetLastError() for these timeout scenarios. Is this an expected behaviour? Can it be changed so I do have access to these timeouts in Server.GetLastError() OR maybe just run this error through "LogEvent" mechanism? Is there a better/more graceful way to handle this issue?

Below is my code to give you an idea, not exactly what I have in my application but pretty close.

<customErrors mode="On" defaultRedirect="~/Errors/ErrorUnknown.aspx" redirectMode="ResponseRewrite">
<error statusCode="500" redirect="~/Errors/Error500.aspx" />

.net - Allow Math To Occur On Instances Of Class?

Nov 27, 2010

Is there some interface I can implement to allow basic comparisons and math to happen as it would an integer?

For example, let's say I have the following class:

Public Class Something
Public SomeBigNumber as UInt64
End Class

I would like to do something like this:

Dim SomethingA, SomethingB, SomethingC as New Something
If (SomethingA-SomethingB) > SomethingC Then
'Do stuff
End If

I was hoping to be able to implement some interface (if that is even the right term for it) that would return the UInt64 contained in the class for comparison and math, if possible.

me and a partner need to play sounds when certain events occur, however, every method we try..

Sound.PlayWaveFile("file.wav") from this class: http:[url]....etc they all don't work

They do NOT throw any exceptions, they just dont play the music, the test demo of the Sound Class works like a charm, its just not working in our project..same with My.Computer. Audio. Play.what could we have done to make it so that we can't play sounds from our application?

PS: this problem occurs on all of the computers we test it on, yet the normal sound-playing methods seem to work on all of those computers when they are implemented in other projects.. its just not working in these instances

BackgroundWorker - Spawn Dialog While Log Event Occur

Apr 10, 2010

I am trying to create a background worker that will spawn a dialog, while a long event is occurring. For example, when the main thread in trying to connect connect to a db and update a large amount of records, I would like to have the background worker spawn a dialog that advises the user to "Please Wait"

Here is what I have so far
1. I create a background worker using the drag and drop
2. Before the event that taking a long time starts I call:
BackgroundWorker1.WorkerReportsProgress = True
3. This is the events for the bgworker, all of which was enabled in the form designer:

Private Delegate Sub delCreateNewForm()
Private Sub BackgroundWorker1_DoWork(ByVal sender As System.Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles BackgroundWorker1.DoWork
Dim d As New delCreateNewForm(AddressOf CreateNewForm)
[Code] .....

4. When the long activity is completed I call this:
Everything seems to work fine, except that the newly spawned dialog in no responsive and appears to be frozen, until its closed by the Progress Changed event.
