Experiencing Error Handling Although No Input Errors
Feb 12, 2011I'm using Try/Catch blocks for a program calculating payroll and commission. I've dim'd my variables, and I've parsed them inside my Try/Catch blocks. It appears as if my Try/Catch blocks have been coded correctly. However when in run-time, my format exceptions will show regardless if I provided a correct input.[code]Is there an issue with my programming? Or could there be a property I'm over-looking for my text boxes? I'm stuck.

What I mean by that is if I have a sub called ImportData and in there I have a for loop to go through a list of files and in the for loop I call another sub routine called CheckData. All have catch error in. If a sub has a catch error in where does it go from its call.

VS 2005 - Error Handling While Updating Contacts
Feb 18, 2011I have a for loop going through customers and for each customer a update a list of contacts. If there is an error updating the contacts I want it to move on to the next customer and if there is an error in the customer update I want it to move on to the next customer. At the moment if I get an error it bombs out of the routine. Here is a simple example:-
For iRows = 0 to oledscustomers.tables(0).rows.count - 1
For iContactRows = 0 to oledscontacts.tables(0).rows.count - 1
'make some changes in here.
Next
Update Contact Table
'Make changes to customer tables and save them.
Next
If I get errors in the contact for loop or the customer loop it comes out of the routine altogether. I just want it to either continue to the next contact or customer.

Asp.net - Handling Errors From HttpWebRequest.GetResponse?
Jul 16, 2009I'm having a ridiculous time trying to get an SMS API working (ZeepMobile, if you're interested) with .NET... I've been around .NET for a few years, but with all this social networking and API stuff, I need to get into the HttpWebRequest a bit. I'm new at it, but not completely new; I was able to hook up my site to Twitter without too much fuss (ie, I was able to modify someone's code to work for me).
Anyways, the way their API works is to send an SMS message, you send them a POST and they respond back to you. I can send it just fine, but every time I do, rather than echo back something helpful to figure out what the error is, I get the Yellow Error Page Of Death (YEPOD) saying something to the effect of "The remote server returned an error: (400) Bad Request." This occurs on my line:
'...creation of httpwebrequest here...'
Dim myWebResponse As WebResponse
myWebResponse = request.GetResponse() '<--- error line
Is there any way to simply receive the error from the server rather than have the webserver throw an exception and give me the YEPOD?
EDIT: Here's my whole code block:
Public Shared Function SendTextMessage(ByVal username As String, _
ByVal txt As String) As String
Dim content As String = "user_id=" + _
username + "&body=" + Current.Server.UrlEncode(txt)

Handling Errors In Try/catch Blocks?
Jun 11, 2011What is the convention in VB when a sub requires that a try/catch block succeed in order to function, but the catch block doesn't bubble the exception up?
I could put all of the code into the try block, but this seems messy since most of it doesn't need to be tried, it just needs the try to have succeeded.
For example, should the catch block exit the sub? This would work in my current situation, and if it is the proper procedure, let me know, but what about the more general scenario where both both success and failure require additional processing?
.net - Handling Errors (i.e. Content Length) Within An HttpHandler

It's critical that I handle any 404.13 (request exceeds request content length) error in the httphandler itself.
I would also like Page_Error to handle any uncaught exceptions but it never fires.

View 4 RepliesVS 2005 Approach To Handling Multiple Tables?
Dec 7, 2010I started out with just one table called products but I had problems with doing an update; it said sql to complex which was because the product table had nearly 100 columns in. The products table consists of header information like product quality, colour etc. Then there are 3 blocks of columns which mainly consist of a size as being the column name and a quantity as being the value. I have put these in three seperate tables to get around the SQL update problem. My problem is what is the best way to code this. The tables link to the header table using an autonumber primary key.

View 3 RepliesVS 2005 - Handling Decimal Type Columns In SQL Server
Mar 17, 2009Decimal type columns have Precision and Scale where the length of the integral part of the decimal would be Precision - Scale, if the Precision is 4 and the Scale is 2 then the integral part can only contain 2 digits (4-2). As such I will probably need a control that I could set how much it should accept on its integral part. In that regard I am not sure which control is best for such cases, I could try to make a usercontrol that will handle that but is there any other control out there that I could utilize for this purpose, intrinsic to .Net or a custom control out there? I could also just validate the data keyed-in but the above solution seem to be more user-friendly. Curiously, when databinding such Decimal type columns, how is it handled when the specified integral part exceeds the allowable size (Precision minus Scale)?
