I have created a vb application connected to MS Database. I have used try..catch statements to trap exceptions and display messages on the error found, but the problem is that these messages are too technical for the end users to understand. Is there a way of retrieving the error number or code of that exceptions thrown so that i can customize the message for the users?

View 3 RepliesAfter researching all the possible ways of sending the output of my program to an email address, I have yet to settle on the most user friendly way to go about this.I have created a form for a property management company I work for. I would like to send the output to a designated email address by a click of a button.Now given that the average user that will be using this software may not be necessarily tech savvy, I would like to make it do this as simply as possible and that means not having to know the smtp. Also considering that the user may not be on their terminal when using this software, using outlook to send the output may not be the best way to go about this. I have tried adding a webbrowser control and sending the email via html but I am not sure if that is the most logical way to do this.

i need an app that can download a table from the db, and when he click a button, i want to update the db with his "offline copy".
Problem is When i use DataAdapter.Update, it doesn't update all the rows. Now this is a problem, because even if his "offline copy" thinks that row 1 is "unedited", some other user may have edited row 1. so regardless of row state, i need to so called "replace" the entire "offline copy" with the database when the user clicks the button in a "last click overrides all" situation
I have developed a paging control that I would like to use in a variety of applications, both C# and VB.NET.I'd like to package the entire thing, markup and all, into a DLL which I can add as a reference from my other applications' bin folders. If this is not possible, or is a very bad idea, what is the recommended method for deploying a web user control amongst multiple applications?(I like how easy it is to utilize Ajax Toolkit controls from a single DLL, although I'm not sure if those are custom controls or web user controls)

Forget fancy shmancy web stuff. I'm looking for a good .NET CLI argument processing utility, prefer open source code. This is for quick and dirty utilities that need robust and friendly command line argument handling.These are utilities with maybe a day of effort in them. Investing a few days writing good command line handling seems overkill but they really need it.Features I like in command line handlers. I'd be thrilled with any open source project that had 2 or 3 of the following.A consistent syntax, posix had a nice command line standard, but not necessarily posix.Ability to provide short names for agruments. E.g. "msbuild /t" == "msbuild /target".It supports good command line parsing then gets out of the way. I want some that my code uses, not something that imposes a pattern on my code e.g. I don't want to have to respond to the presence of an arg with an event, that type of thing. Seperation of concerns is good enough that it's logic can be unit tested. Oh - is it two much to ask for it to read attributes off a class properties (as in .NET configuration classes)? I like the config file overrides in msbuild. I can set properties in a build file, but override on the command line. Built in "show usage". WSF files (csript.exe) have this functionality. I'm not willing to write jscript to get the command line handling though.Not powershell. I can't find anyone in my company who can stand Powershell syntax.

My current program is reading a XML doc and using it then moving it to a different directory to be archived once it is finished using the xml.
I want to be able (upon completion) move and rename the file to a new folder, I want the folder to be the current date/time as well.
So basically have 4/4/2011 9:56AM.xml in the folder 4/4/2011 9:56AM.
getting the function DateTime.Now in a format that can be saved. Folders and files cannot contain the " / " or " : "

I like to user custom errors in my site. The Idea is to trap errors and display friendly meaningful messages to users. The real error details (line number, Page ...) will sent to me by e-mail. I am programming in VB.NET. Until now every code that i found about this say's that i must use the global.asax for it. I do not like to use global.asax, I just like to make an error page that will sent me a -email with all the error details. Until now, I go to the web.config file and insert this line:
<customErrors defaultRedirect="test.aspx" mode="On"></customErrors>
test.aspx looks like this:
Sub Page_Error(sender as Object, e as EventArgs)
Dim ctxOBJ As HttpContext
Dim exceptionOBJ As Exception
Dim errorInfoTXT As String
[Code] ....
When here is an error in some page its redirect me to test.aspx but not showing any error.
