Stack Expansion In Application - Lend Themselves To A Non-recursive Environment
Dec 28, 2011
I have a not too complicated problem which I do not know how to solve in vb2010. Currently I have a recurive routine for finding files/and or searching. With a recursive routine I never complete the call until the end and process growth is significant enough to radically slow down the process with the now large stack. To make maters worse, I use precoding routines which will take wildcards. which are these:

I was surfing the next to get some of the powerful elements that .NET has over other langauges when it comes to VB.NET and I was told to learn delphi.
Since this is a VB.NET forum I was hoping you guys could tell me why I should stick with VB.NET over a language like delphi.

Suppose in .NET (don't care what language) I want to show a user a PDF, Word and Excel file together. I am trying to replicate a document process where a user might have a PDF file and he would like to attach a WORD file and an Excel file let's say to make a stack of documents (that I would save in some directory). Then he would like to click on a button and see a stack of these documents in 1 application of some sort.How can I display the stack of documents WITHOUT first opening WORD, then openinig EXCEL and then openining ADOBE ACROBAT - this would be really annoying for the user. I would like one unified application or some idea to mimic one in .NET that can just show all 3 documents as if they were printed one after the other on paper. (I hope I am explaining this clearly)

I've seen sample vb project. It's a console application. There's a code there like Dim q() As String = Environment.GetCommandLineArgs()
First I try to check it by using message box to print it out: the index-0 of q contain a path project vshost --> q(0)="D:TestServicesample1.vshost.exe" and the index-1 of q contain a xml file --> q(1)="Setting.xml"
The thing I really confuse is, from where the Environment.GetCommandLineArgs() get that both q(0) and q(1)?
I've tried to search both and can't found any code which is contain the path to load it, then I try to delete the all complied files in debug folder and then rebuild it, the strange thing happen, I mean the "Setting xml" file automatically created and appear again although it doesn't has the same contain as it has first which is remain only. The original contain of the Setting.xml is some IP and database name. Is there any setting which can make the vb.net create the Setting.xml? Because I don't find either the code for creating this Setting.xml or the tool bar for set it.

I think my title covers the high level, but for indepth; i need to be able to connect to a machine through and ip and set a enviroment variable, i have over 60 machines in different states all on one network that i need to do this for as well as someother things for the machine. currently this is being done through a PCEXEC command in a batch file they want more control on how this operates. I just really have no idea where to even start looking for the enviroment variable change(setting one on a machine that the app is running is simple we all know that. but on a external machine im lost) on a remote machine.

Today I encountered this article about decimal expansion and I was instantaneously inspired to rework my solution on Project Euler Problem 26 to include this new knowledge of math for a more effecient solution (no brute forcing). In short the problem is to find the value of d ranging 1-1000 that would maximize the length of the repeating cycle in the expression "1/d".
Without making any further assumptions about the problem that could further improve the effecienty of solving the problem I decided to stick with[code]...

I have a bit of a weird issue. We use DevExpress controls to do all our Windows Form development. Anyway, I found a perfect use for the DataRow.SetParentRow/GetParentRow methods in my grid. So I created a DataRelation, added it to the DataSet and bound it as the data source for my grid. The issue is I now find this:On my grid. It seems to be the DataRelation (when I mouse over it the tooltip is the DataRelation name).

FormA calls DialogB where user cancels DialogB which exits via ForceTermination(), see insert.Caller FormA check for DialogResult not = OK, which it isn't, and I can see this in debug as Abort(3).However, the code continues merrily along its way until I get a 'null reference' error which I'm trying to avoid via Force Termination().This is caused by the user cancelling DialogB, a selection process to get a database (SQL) instance.[code]

In your actual programming experience, how did this knowledge of STACK and HEAP actually rescue you in real life? Any story from the trenches? Or is this concept good for filling up programming books and good for theory?

I'm trying to recolor all components in a form by using a recursive method. However, it always recolors the form and then stops. How can I make it go past this step? Here is the code I've been experimenting with:

I am hopeing someone can help me here with a recursive function I have that is not returning either true or false as I would have espected it to. The function loops through a Active Directory group for its members and then calls itself if it encounters any groups within the membership in order to gets its members as well. I am trying to return either true or false based on if any errors were encountered but not haveing any luck at all. It appears to just hang and never return back to the primary calling sub that starts the recursive function. Below is my code I am using:

I've started using .Net's stack collection. The basic features I guess are the "pop" and "push", where you add or take off the top element of the stack (if you are referencing other elements in the stack then another collection type is probably better).[URL]..it appears that the Stack collection (like other collections) is basically an array with some window dressing (so you actually can see other elements). As far as I can tell, "popping" and "pushing" is changing the first element of the array. Shouldn't instead the final element be the "top" of the stack and be the one that is changed? Otherwise the program has to reindex all the other elements in the array every time a pop or push is made. This seems very inefficient. But this is what Microsoft's description appears to be saying what is happening.

My problem is that i need log the stack call. I know that i can put a breakpoint in code and choose the debug menu option "call stack", But that is not a solution for me, because i need all the methods called by the application, not only the last until the breakpoint.

I just started programming in VB.NET 2008 with the Express edition and have been having a blast so far. I thought a fun program to try and make would be an infix to postfix program.
I have five text boxes off to the side of my program that shows what is on the stack as you iterate through the equation. I'm wondering if it's possible to make these textboxes set to display what is at a certain index of a stack.
For example, if I pushed a "(" onto the stack, I would like the top box of my textboxes to update and show a "(". When something else is pushed onto the stack, say a "/", I would like the "(" to be displayed in the second box down, and the "/" to be displayed in the top box now.

We have this funky little ObjectDisposedException happening now and again. But only on production machines, of course ... can't recreate the issue on my dev unit. So I trotted on out to the Microsoft site to see what members of this exception I could use to figure out what's going on. Microsoft says that one of the members is StackTrace. I double and triple checked that I'm looking at .Net 1.1 information as I'm pretty sure that's what I'm using (how can I check that?). Here's the page I found - [URL]
So I go back to my program to write something useful to the event log so I can figure out what's going on. And when I look at the members of the ObjectDisposedException available to me I only see the following: GetBaseException, GetType, InnerException, Message, ObjectName, ToString.
what happened to my StackTrace member? I sure could use it if I could figure out how to get to it.

As a learning experience I decided to try and implement the Shunting Yard Algorithm(string calculator) using OOP. It was successful for as far as I took it, but it had one flaw. In order to get the stack to be accessible from the operators I had to declare it as shared, which meant that all versions of the calculator shared one stack. This very short piece of code illustrates what I came up with and the "flaw". [code] How can I maintain the functionality of anOP.add1 without declaring "something" as shared?
