VS 2005 : Catch Program Write Commands?

Mar 31, 2009

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...

Write A Windows Forms Application That Responds To A Limited Set Of Voice Commands?

Mar 11, 2010

The goal -- use VB.Net to write a windows forms application that responds to a limited set of voice commands after the user says a keyword, (such as "Wake Up"). I have the following code I am using from another site but I am getting an error I do not understand (nor do several others who posted comments at the same site.)

Imports System
Imports System.Data
Imports System.Deployment

[Code].....

If I had any understanding of how to create a grammer file I MIGHT be able to avoid this error completely, since I am only interested in a few voice commands (maybe 30), not the whole 60,000 word dictionary.

How VB Can Focus A Specific Program And Then Send Commands To The Program Only

Aug 3, 2011

I am trying to figure out how VB can focus a specific program and then send commands to the program only. The focus would only be for the commands and would not make the program you are currently in lose focus. Simply, what it is controlling is a Windows Application called GOM Player. I use it to study my material for school. I plays movies in it and don�t have to click out of the application I am working in to pause, play or rewind. The keypad and the company who make it actually have it built into iTunes and it does exactly what I want GOM Player to do.

The reason I dont just use iTunes is because I can�t get my video files to play in iTunes. After pulling teeth with the manufacture I finally to tell me that the iTunes functionality is accessible via plugins built into iTunes. So trying to mimic what is being done there does not help. I believe that a knowledgeable VB programmer could answer my question in seconds, but having some experience with coding and programing I know it also could be a lot more than what I think. [URL]

The question is: What is way that VB can send the key for the macro only to the GOM Player Application even if it is not focused or even If it is minimized.

Terminate A Program Immediately From Try Catch?

Jan 19, 2010

I 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.

VS 2008 Catch ALL Errors Of The Program?

Jan 12, 2010

Is 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.

Use Speech Recognition With Voice Only Triggering Commands In The Program?

Aug 11, 2010

I am using system.speech currently. I want to use speech recognition to make a program. However, while the program is running, I noticed that some of the commands for windows (like saying "run") would trigger other program functions. Thus, while the VB.net program is running I do not want this to happen. Also, when the computer starts up, I speech to start listening right away rather than me having to say "start listening". How can I do this? I am pretty sure that it is simple. This is my code so far:

Error - Catch Cannot Catch Type 'Microsoft.Office.Interop.Outlook.Exception'

Mar 25, 2011

I 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.

Catch Log4net Exceptions / Use Try / Catch Approach

Jan 23, 2012

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.
