List Of Most Common Errors?
Nov 2, 2009When I was learning QBasic I found a list of most common errors and it told me whether my errors were syntax errors or logic errors. Where I can find a similar list for VB 2008 Express Edition?

I am coding in vb.net. I migrate a project from vb6 to vb.net.In my migrated project I'm pretty sure there are close to 200 errors.but in ErrorList it show only 102 error. So, my question is how can i get all errors at a time in Error List.

View 4 RepliesI have a large solution which contains a mixture of C# and VB.Net projects.If I get compilation errors because a project which several other projects depend upon fails to build, it is very hard to see the actual error(s) because of the number of VB errors in the error list window in Visual Studio. C# errors found in the projects I compiled show in the error list, but all VB errors appear (including in those projects I have not just compiled).Is there any way of turning off this behaviour so that VB errors only appear for projects that I have explicitly compiled?

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" />

View 2 RepliesIn the old VB, there is a .bas file wherein i place all the global constants there and whenever i create a new project i just include that .bas file so that all the constants i placed are automatically added to my project. Is there any way to do this on VS2008? Ill be doing dozens of Class Libraries that that needs to reference global constants.
1. Is there any other way of referencing the global constants rather than making it a shared variable in a class?
2. Also, is there a way to include a .VB file without the copying it on the local project file? My point being is that this .VB file is also being used by other Class LIbraries that i created.
Is it possible to set up a common event handler for a group of like controls like buttons or text boxes so a single event handler is called regardless of which of the controls is clicked, changed, etc.In my PrinterDialog study project I have 5 text boxes named TB1, TB2, TB3, TB4 and TB5 in a text box array called TBs so they can be accessed with TBs(0), TBs(1), etc.My question is if I can set up a single click event that responds when any of the 5 text boxes are clicked to avoid duplicate code n 5 different click events.

View 2 RepliesStarting from a table like this:
| Code | Year |
---------------
| A01 | 2001 |
| A01 | 2002 |
| B01 | 2002 |
| C01 | 2003 |
I have to arrive to this:
| Code | Year |
---------------
| A01 | 2001 |
| B01 | 2002 |
| C01 | 2003 |
I have to group the first column (Code) and from the second (Year) I have to get the data 'less common as possible' compared to all the other records. I try to explain this with the example: for the code 'A01' I have 2 years: '2001' and '2002'. I have to take '2001' because it's the one that not recurs in the other records. In the case that there aren't available values 'Year' that not recurs in the other records, it's good to take whatever value.
The data are in the form of array in memory and to interact with them I'm useng some LINQ queries.
Essentially, whenever my users who are logged in via a global module level variable enter a new form, their activity is "logged" in a textfile with their UserID as the name.txt and every time they visit a page it adds a new line to their log file with a number corresponding to the form they visited. For example, if they select "add a user" it will add the line "1" to their log file. Note: At the moment there is only 1 2 and 3 not 0.
I have got this far and I have got as far as creating an array which has:
Array(0) = NumberOfTimes 0 appears in the log file
Array(1) = NumberOfTimes 1 appears in the log file
etc etc
Therefore the output for this is
Msgbox(Array(0)) shows "0"
MsgBox(Array(1)) shows "4" for example and lets just say
MsgBox(Array(2)) shows "9" and
MsgBox(Array(3)) shows "1"
Therefore, finally (!) my problem is now finding which 3 are the top. I have tried various methods of sorting them but I just get "9, 4, 1, 0" rather than "2, 1, 3, 0". (By the way the end product for this is to show three links on the "welcome form" of the users 3 most visited forms). Here is a pastebin of all the rubbish I have currently tried that hasn't worked!

i made an application using VB.NET 2010. i have 5 forms. i want to know how to make one common navigation (like in a webpage) for this application. Is it possible to have the menu and header static and loads each form in one dynamic container. I hope my questing is clear :P just to make it more cleared, it is more like having a templates in php coding where we can load other page in a particular area without having to reload the entire page with each links.

Here is a complicated, but possibly dumb question concerning adding projects together in the IDE in order to increase performance and share memory at the same time.I have written two distinct exe's. The first exe (file processsor) operates using three timers to perform communication between a hardware OEM proprietary ComServer and file output from the second exe. The second exe (work generator) simply outputs files on hard disk so that the "file processor" can process the commands in the order given. The first exe was written as a "background processor" to the second exe in a stand-alone fashion. There is a need to communicate data between the first and second exe that is time sensitive. The ComServer called by the "file processor" only allows one port to for communication to the hardware device that is a USB. The "file processor" is capable of extracting the data required but the existing technologies, such as RPC, IPC are too slow and or full of pitfalls. Microsoft's Memory Manger has found it easier to create multiple instances of the proprietary ComServer and assign the needed memory to the calling routine so that it can "scoot" memory easily in the garbage collection feature of the operating system. What this does is cause the mullitple instances that are created to "gang up" on the device either slowing its performance down, or causing time outs. [The second process is a custom 3-D graphical CAD/CAM. The first process is a machine interface. Although hind-sight is 20-20, it seemed more ideal to write this background or file processor independantly, as then it could communicate with existing as well as a custom CAD/CAMs.]
Simply writing the first processes' code into the second slows down the second process as a result of all the timer interrupts looking for work to do. (Mouse is squirrely, screen refresh is slow, etc.) I am only guessing here that the operating system's service of the more complicated single memory location is somehow interrupted more frequently for a larger project, than two smaller independant projects running seperately. I only know what I observer here. Interestingly, the two smaller projects running seperately seem to run fine.
Now for the dumb question. Is it possible to merge the "file processor" with the "work generator" in the IDE such that each process runs as independantly as two distinct apps, but at the same time, make it possible to share memory via one Module1.vb? So far, I cannot find a way for the "file processor" to see the "work generator's" Module1.vb, regardless of how many PUBLIC statements I issue in the code. In other words, what would be the steps after File->Add-> Existing Project to cause the "file processor" project with a form to start first, then drop to the background, followed by launching of the "work generator" second where each process shares the same Module1.vb?.
If this could be done, say through a compiler statement, or whatever; then this could make the Memory Manger folks happy, and provide for the speed required to operate real world processes? Basic computer science suggests a simple processor LD instruction could make data available to any application within a few clock ticks. Microsoft now longer allows direct memory access, or the ability to carve out a "stay resident" dll in memory where a memory location can be called for quick distribution information to all apps with just one call to a device.
There are 3 project in vb.net MAIN PROJECT, BLL(Business Logic Layer), DAL(Data Access Layer) now we are trying to maintain one single instance of some values through out the assembly or what we can called single instance should get used in all projects...for example there is a class called clsParameter we need only one instance of this class should get used through out all projects so if i made any change in MAIN PROJECT same values also get updated in BLL or BLL should receive same values....
