I am a sys admin for a company and our programmer left several months ago. a program they wrote is now failing and i am struggling to work out why. the program basically pulls data from a csv file into a readable form, written in visual basic. the application works on a couple of machines but not on a couple of others. i have matched up .Net framework versions, MS Primary Interop Assembly versions, still no joy. As the app works on some pc's i am wondering what other differences could cause this?
The error output is:
see the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.
Exception Text
CODE:
JIT Debugging
To enable just-in-time (JIT) debugging, the .config file for this application or computer (machine.config) must have the jitDebugging value set in the system.windows.forms section. The application must also be compiled with debugging enabled.
For example:
CODE:
When JIT debugging is enabled, any unhandled exception will be sent to the JIT debugger registered on the computer rather than be handled by this dialog box.

good database that I can use on a local machine to store names/addresses etc. and that integrates easily into .Net 2.0.I have used MySQL a fair bit, so something along that route would be great but without the need to install additional software on the computer or connect externally to a server.

I am having some difficulty with an xPath expression. I am using an XML document to store queries / stored procedure names in an ASP application. I use a utility function to load the xmldocument (if it isn't previously loaded) and I am attempting to select the node set from the document that matches an Id element. [code] the node variable only returns the first element. I have verified the that the qry string that is used to SelectSingleNode IS the correct Id value (i.e. USER002) - however the node is getting loaded with the USER001 element. It is obviously the xPath expression that is messed up. What do I need to tweak on the xPath expression so that I can return the correct <Id> element and corresponding child <Sql> element.

I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Close()

I am trying to create the following program Store in a 1d array a set of 5 place names and in a 2d array the distances between the places. Ensure that the order of the places is the same in both arrays. When the names are places are input the distance between them is displayed. If they are not both in the table a suitable message is displayed
Dim town(1 To 5) As String
Dim Dist(1 To 5, 1 To 5) As Integer
Dim First As Integer
[CODE]......................
I think the best way forward is pass a parameter to the function findnumber.

I have build a program until now with an MySql database. The programs add records for the customers and the products of the company(Its works perfect).. I am trying to build now the Orders the last part of my project but I have a little problem.. First of all I need 4 different type of database:
Cash
Credit Card
Check
Debit
Price Offer
This is the the type of the payment. The user must add the order by the payment of customer so we need to seperate each one.. Unitl here I am fine::
Now, my serious problem is with the order table:: If i used the code that I use for my other adding records (like product and customers ), for each order it's add only one product!! BasicallyI need to be able to add multi products and the user have the ability to change the price of one product:: for example "to make an offer for some special customers" without change data into the database of products..Thats has a lot of typing code but I need a base to start since I have a little bit of confused. At the end am trying to load data from database customers into text boxes:: for example the user select one name that loaded into a combobox and then appears the city and the mobile into a text boxes I build a code below but it's works only One type, actually fill the text boxes but after I clear all the boxes and try for a new customer or the same isn't fill anything.
Dim ServerString As String = "Server=localhost;User Id=root;Password=root;Database=test" ''Sting Server
Dim SQLConnection As MySqlConnection = New MySqlConnection ''SQL Connection
Dim Sql3 As MySqlCommand = New MySqlCommand("SELECT * FROM customers", SQLConnection)

I am doing work for a client who has lost the source code for one of their VB.Net WinForms applications. The assembly they have is not obfuscated at all. I am trying to recover as much of the source as I can as C# source and have tried several tools for decompiling assemblies, including Reflector, ILSpy and JustDecompile (all the latest versions), but they all produce code with a huge number of errors in them. Because of the large number of errors in the generated code, I am going to ask about the specific errors (in different questions), get more directed answers and in this way try shed some light on why all the tools are having difficulty decompiling this assembly. This question pertains to the fact that the code generated by all these tools always have a large number of invalid member variables (fields) such as the following:
private short $STATIC$Report_Print$20211C1280B1$nHeight;
private ArrayList $STATIC$Report_Print$20211C1280B1$oColumnLefts;
private StaticLocalInitFlag $STATIC$Report_Print$20211C1280B1$oColumnLefts$Init;
why the generated code has these invalid member variables?

I have a class SELF that is hosted by a couple different classes. Basically, the hosting class HOST calls a method in SELF. SELF is passed HOST as an argument in the constructor, so SELF can call methods in HOST. In normal situations, a call to HOST will do something minor, then return so that SELF can continue. However, for one particular type of HOST, one of the calls from SELF to HOST will cause HOST to call SELF, and so on ad infinitum. A classic, though convoluted, case of recursion. Once again, this is only going to happen for one type of HOST. For other types of HOST, that particular call will not cause HOST to call SELF, so there will be no recursion. Nonetheless, there is no getting around it in one case.
I can see two means to decouple the recursion, and I am wondering which one (or a third) would work best:
1) Add a timer into that particular HOST so that the call from SELF that would trigger the recursion would actually just start the timer in HOST, then return. When the timer ticks, HOST can call SELF. The recursion is broken because the call to SELF is done on the timer event, and not when SELF called HOST.
2) As it happens, HOST makes the first call to SELF in a background thread, which means I don't really need to worry whether this thread blocks or not. Therefore, I could have this background thread spawn a second background thread to make the call to SELF, then have the initial HOST thread JOIN on the second thread. This means that the initial thread will block until the second thread finishes. Meanwhile, the second thread will call HOST, and the HOST won't call back to SELF, it will just return like all the other HOST objects would do. This will allow the second thread to run to completion. When the second thread completes, the first thread will take over and call SELF again on a new second thread. Therefore, the recursion is broken because the secondary thread will always run to completion, and the primary thread will wait for the secondary thread to complete, then call it again.
I tend to prefer the second option, because the first option involves a pause of some length (the minimum for a timer, which is pretty small), while the second doesn't, but the first option is actually a little easier to implement.

I have a filesystemwatcher that watches a couple of folders! The files coming to the watched folder are coming from a server. And for some reason the created event is not raised..If i move the files for a sec from the watched folder to a another folder and then copy them back to the watched folder it all works fine! Strange.So if the created event is raised from the same computer that the service is installed on it works great, but not if the files are coming from another computer.

Very new to web development and had some session issues a couple of days ago. I have those now resolved but having trouble telling the page to redirect home after the session expires.
Using the example from my previous post:[URL].. I have this set in areas of my main page in order to redirect if the session has ended.
If Session("UserClassInstance") Is Nothing Then Response.Redirect("Login.aspx")End If During the testing; after Session_End fires, I go to the control that contains the above statement but seems to think that the session not nothing and will not redirect.

I can't seem to figure out how to write this query properly. I've tried various combinations but nothing's worked yet.Below is the relevant portion of my database model:
I need to select the products that match a given Category and Group, and that match a given Year, Make, Model, submodel. This I've done below: ItemList = From P In gDataContext.Products.Include("Groups").Include("Groups.Category1").Include("LookupYearMakeModels") From G In P.Groups Where G.Category = Cat And G.Grp = Group From Y In P.LookupYearMakeModels Where Y.Year = YMM.Year And Y.Make = YMM.Make And Y.Model = YMM.Model And Y.Submodel = YMM.Submodel Select P
