View 6 RepliesUsing Excel Automation classes I am seeking to save an Excel file as a delimited text file. The examples given in the MSDN library refer to versions older than Express 2008 with (apparently) different syntax options for FileFormat.Based on the snippet shown, I get a COM exception error (800A03EC). Other variations produce the same error.
Am I improperly applying the Automation features?

In my ignorance, the best way I was able to find to move those common methods to a separate file was in a Module.

View 10 RepliesI am creating a class ("Class B") which is used by another class ("Class A") which instantiates it in VB.NET 3.5.I would like Class B to read a value assigned to one of its properties by Class A every time an event happens in Class B.However, I would like this property value to be dynamically assigned to the property by Class A when the event is fired in Class B.I was thinking about somehow creating a delegate function in Class A that is linked to the property in Class B so that when the event is fired in Class B it would eventually invoke the delegate in Class A so that it returns a value to Class B.I've been reading around delegates (that's how I arrived at the idea), but I am stuck on how to code this up - could someone please help with some skeleton code?

We are trying to identify the best archtecture while using a ORM like LINQ to SQL. The archture we are defining is for sort of framework that other applications will access either trough directly referencing the DLL or through a webservice. We have .NET apps and PHP apps.The possibilities are: Multiple data contexts: Separting the database into units of work and create separate contexts for each one.
Pros:
Easy of use
Classes will be broken into different namespaces
Smaller domain to maintain
Cons:
Objects have to be duplicated if
related, creating maintenance hell
Objects cannot be passed between context, creating the need for another hit on the data base Single data context: All tables, views, procedures, reside in the same huge context.

I have a large string in which I need to replace specific strings with other values. For example, within this string I might see the following characters: [[sub id=5]]. I am trying to replace those substrings with values, pulled from a table and based on the id. What would be the simplest way to accomplish this. My first thought was to loop through and examine each character and note their positions when they match the pattern. I would then have to identify the id. That would be fairly complicated, however, and there must be a better way.
