today I finished my VB project which is a program that generates costs of pizza's by what the customer order. The code is all complete just looking for some idea's on to stop bugs and clean up the code. So below is all my code and picture of the form. Errors occur when someone doesn't pick a value, so what i want is there to be default values as 0.
[Code]...
When I publish the program. Is there any way to get VB to publish the text files with the program so that no errors can occur. When I install and run the published program I get a series of errors relating to text files that are not found.
View 4 RepliesThe 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.

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
xmlDoc.LoadXml("
< main1 test1 = 'any' test2 = 'any2' >
[code]....
Why does the following return only the elements, and not the attributes:
For Each objnode As Xml.XmlNode In xmlDoc.DocumentElement.ChildNodes
Console.WriteLine(objnode.Name)
Next
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.

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
[CODE]...
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
[CODE]...
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.
EXAMPLE 1:
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]
EXAMPLE 2:
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]
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.

Private ProgRunning As Boolean = True

[CODE]...
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.
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.

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.
I'm not sure what happened. I saved my project last night and everything was in working order. I opened it this morning and it's not recognizing a lot of the System methods and functions

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

I have just received an interesting feedback from a VB.NET customer using our product - for some reason intellisense hidden a certain enumeration value.After a small testing I have found that this is likely a bug in IntelliSense: [URL]..To be honest, I did not expect this problem with such a basic stuff like this. Have you seen this in the past? For me, it doesn't work in all VS versions...
Anyway, feel free to track this issue if you are coding in VB.NET.
It is saved on my desktop for easy access.I can close the program. I can click the solution to open it right back up, no problems.I then zip my file (also to the desktop)
My problem: I moved the original file (Project A) to another folder and extracted the unzipped Project A onto the desktop. When I open the new Project A's solution file, nothing happens besides VB starting up. It doesn't show me anything.
In my application, i have put a question on form closing if the user wants to save the changes?. But right now, i have just put it in default whether they make changes or not.I thought of prompting it on text change.. but the text automatically changes on load as it retrieves data from sql server.

or?
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
