View 15 RepliesIs there a way to catch ALL errors of the program?
Purpose: The idea is to catch all the errors of the program, load errorform which basically just says "A Error Was Detected" (Which I have already designed). Then send a web request to a formmail.php file with the said error (which i have already done).
In short: I need a way to catch ALL errors, and get the error string that it gave.
This is part of my block which handles incoming messages via TCP. Sometimes it sends scrambled messages which are unpredictable and i need a Try + Catch block for it:'
[Code]...
I can either get "Input string not in correct format" or "typecast not valid". But this is simply supposed to be routine to run into and be able to handle. but that stupid error message keeps popping up I've heard of JITDebugging, should I use that?
Is there anyway to catch or display the request failed with an empty response message somewhere other then in a message box, for a example in a text box? Catch request failed with an empty response message

View 6 RepliesI am in process of writing a setup program that will reside in a USB stick.After inserting the Stick the VB2008E program starts (dont know how) and guides the technician to do certain tasks. As a part of this She/He needs to run a Setup.exe that resides in the same USB stick.
1- How do I define the drive letter of this USB stick.
2- How do I run the x:Setup.exe program without exiting the VB2008? The install process should begin after click of a button.
3- Would Autorun work on USB drives to run the program automaticaly?
4- How do I compile to make a single EXE file at the end?
When I do the try/catch method in my vb.net project I will try the code I want and when it can't do it, i make a message box right after the catch method. The thing is that it will show the message box, and then another message from the program itself. Like for example, I have here a MySQLException, and when i click ok on the message box, it will show another one right after showing the exception itself. How would I be able to get rid of this so the user doesn't have to see this, and the program can continue.
View 2 RepliesIn Form1 there are a lot of boxes like checkbox, label....I want to show a processing message for opening serial port after program running. So I created Form2 specifically showing "Opening Port...". So in Form1_Load() I used Form2.Show(). However this message showed behind of Form1. I think this was executed before all the other tool boxes loading. So where should I put Form2.Show()?
View 2 RepliesI am using VS 2008 VB and setup my application software in Win XP without any issue. But after installed in Win 7, it doesn't work well (it show one file not found, but I saw the file in the right folder). Could it be the incompatibility of VS 2008 and Win 7? If I upgrade to VS 2010, will the issue be fixed?

View 1 RepliesI am trying to end a program immediately when a critical exception is caught. But I am finding that code after my Try/Catch block is executing even though the code withing the Catch block is executing, and that Catch code is calling Me.Close.
I suspect it has something to do with background .net threads or something, but I have no clue how to deal with those kinds of issues. How can I stop the program as quickly as possible? If code after my Catch executes, it will (and does) throw lots of uncaught exceptions later. Currently, it is not feasible for me to try to catch all the other exceptions. I just want to report an error and end the program.In my form load routine, I create and set up a number of objects and arrays by calling various subroutines.The success of most of the subroutines depends on the sucess of three subs in particular, which are called early on. If one of those three fails, there will undoubtedly be a number of hard to trap exceptions later on in the load routine.

While running an application in the IDE, the program properly handles Try/Catch/End Try blocks. This works fine for the most part, but is it possible to have errors generated in these blocks stop execution at the line with an error on encountering an error?
Is it possible to intercept any program write (to file/registry) commands and prompt the user to allow, while pausing the other program's command? Antivirus thing. I know, this seems impossible. But there must be a way! Even if it's just possible to notice what's happening and save another copy of the to-be-affected file first...

View 9 RepliesI have a program in VB.Net that receives mails from Outlook, extracts attachments and inserts the attachments into a table through a query. I would like to put the query/queries in a Try/Catch block, but cannot do so as Outlook exceptions cannot be caught, and it gives me an error, and unless I put a very specific exception, I cannot catch it. Is there a workaround?
Edit:
Try
Catch ex As Exception
End Try
Exception is underlined and when I hover on it, it says: "Catch cannot catch type 'Microsoft.Office.Interop.Outlook.Exception' because it is not in 'System.Exception' or a class that inherits from 'System.Exception'". This is affecting all my other code which I'd like to put into a Try/Catch block.
The following code causes a "Warning" that Variable is used before value assigned.How do I restructure this Try/catch to eliminate error on the myreader.close command in the Catch part? Code appears to work fine but I dont like Warnings. [code]

Private Sub sub1()

View 2 RepliesI am really confused! My program doesn't work if I don't have Visual Studio here in my PC. To test it I have uninstalled Visual Studio. But my program doesn't work though Flash Player is present there (I have used Flash animation in the first form).
To be more sure about it I have installed Flash. But it's not working! That means the Flash animation file (.swf) is not making a problem! It needs support from Visual Studio to start. Doesn't it mean that some files are not attached with a setup file as a result it needs Visual Studio to run? Let me tell you how I create a setup file of my program.

I need to catch log4net exceptions (its own exceptions not app exceptions logged by it). I wish there's a way of doing it this way: [code] I have this code implemented and there's no errors in compilation but i force log4net to have an error (pointing to a non existing database in the config file) and nothing is threw.I've tried the listener aproach: [code] and it's writing the errors to log4net.txt, the forced ones i mean.This last aproach has a couple of drawbacks: it won't append every error to the file, if the error is the same it doesn't write it, i can't get the listener to write every error to that file, only one (I don't know how to fully configure the trace listener, it might be that). Thus it won't append the date and hour to every line wich is a necesity for me. Finally i can't give structure to it (xml). Even if the listener work i need to use the try/catch aproach, since i'm using ExceptionHandling from Enterprise library to log the errors in my app.
