Get A Multiple Number Of File Types?
Feb 21, 2009
I am not sure I am doing this correctly,I want to get a multiple number of file types (gif, jpg, png, etc.) and store them in one variable so I can access all the files in that var. I read that GetFiles doesn't allow for multiple patters, so how do I do this so I can have more than one file type in a variable?
Dim aryFiGif As FileInfo() = di.GetFiles("*.gif")
Dim aryFiJpg As FileInfo() = di.GetFiles("*.jpg")
Dim aryFiPng As FileInfo() = di.GetFiles("*.png")

I'm writing a program that saves 'map' files to the HD so that I can open them later and display the same data. My maps originally saved only one data type, a set of my own custom objects with the properties: id, layer, x, and y. [code]...

Is it okay for a structure variable to hold a small number of reference types? I thinks it's fine because the pointers themselves are not that big, regardless of what they're pointing to. But I never did fully figure out the whole heap/stack thing, so I'd like to make sure.

So you know how PHP internal functions usually return a boolean FALSE when a function fails, or some other data type when the function succeeds? Is this possible in VB .Net?For instance, lets say this simple code here Public Function TrySomething(ByVal Param As String) \what would go here??
[Code]...
You see I want to return a BOOLEAN false when a function fails, and a string when the function works. I've looked everywhere, and when I search for "return multiple types" all i find is Tuple.

I have a series of documents (Crystal reports, Excel workbooks, Word documents, PDF documents) that I need to print out in a collated order, but it seems that each application runs on its own thread and the documents don't come out in the order I intend.Is there a way of using VB.NET code to (a) control the order in which the documents are published; and (b) compelling the system to wait until one document is complete before starting the printing of the next one in the sequence?LDC

My brain is fried at the moment, so here's the scenario.I have a form that adds a member to my VB.NET application.When I press submit I add their details: name and number as well as what products they want (internet and phone). Internet and Phone are their own class as is member.
I want to add that they HAVE whichever they have chosen and with the member store it.
[Code]...
As what happens is once the member is created (stored) I will go to input how much they have used, and then store that. But to do so I will need access to the internet and phone classes, which are associated with said member.

I'm having a bit of an issue with this program I have been working on for my class. It's a future values calculator, that takes a single data type, decimal data type and a integer data type does the formula and then spits back out the Future value. What i'm having difficulty with is converting the string over.

So I've recently been vexed by problems similar to this one: Oracle .NET error - Wrong number or type of arguments. I know oracle is famous for its terrible error reporting, but this is a giant pain to debug -- if you have ten parameters, that's twenty things to check by hand (types and names,) not to mention the actual number of parameters, and if they're actually legitimate values.
Is there some way to get better diagnostics on stored procedure calls to oracle?

I have a class with a Property called 'Value' which is of type Object.Value can be of any type, a structure, a class, an array, IList etc.My problem is with the setter and determining whether the value has changed or not.This is simple enough for value types, but reference types and lists present a problem.For a class, would you assume that the Equals method has been implemented correctly, or just assume that the value has changed every time the setter is called?If I did assume it's changed, then perhaps I should assume it for value types as well, so that the behaviour is consistent.

In VB.NET I would like to create a complicated data structure with multiple types of data stored in an array like format (see below). I am trying to create a data structure that would look something like this: [Name; xLoc; yLoc; zLoc; [Jagged Array]] Note: Name needs to be dimensioned as a string, xLoc and so forth as integers. The Jagged Array would look like this:

Does anyone have a nice sample of a unit convertor handling multiple unit types that I can integrate in my application? I have found this one, but it is only handling one type of unit. For example I want to convert weight as well as volume from and to imperial units.

I have gotten my application to open with an associated file type, but now I'm trying to figure out how to associate the file types to the app. I associated them on my PC manually by right clicking on a file and selecting "Open With.." and check-marking "Always use this application to open this file type".What I want to do, is have my program make itself the default application for a file type with the press of a button.If it makes it easier, I'm writing a text editor and want to give the users the option of making it the default text editor for .txt &/or .rtf files.

I am currently working on a document manager type application in vb 2008.
I want to be able to open and preview different file types in the app in addition to being able to open them with their associated programs.
Is it possible to create a universal file opener that will open and display any file type (and if so how do I do it) or do I have to write a separate file opener for each different file type I wish to support?

A colleague has written a useful tool. He wrote it as a standalone tool, but it works even better as an includable dll, though it needs a bit of other functionality for it to be a really good drop-in component. What I am wondering is whether a project can be compiled as both an exe and as a dll?
There are alternatives, such as having a dll version and an exe version, since the dll version needs to include a few different methods that the exe version doesn't need, but this alternative sucks, since it would mean changing two sets of code.
Another alternative is to build the dll, then change the exe to be a project that references the dll....and does nothing other than calling one method in the dll. That kind of sucks, too, but not as bad.
I want to be able to use his module in some of my programs, and it really should be built as a component rather than a standalone app, but I want to know whether there are other options that I haven't considered.
