Parsing String Each Iteration, Or Parsing Once And Storing?
Mar 16, 2011I'm creating a vb.net winforms application that will take in user given strings, parse them, and print out labels with variable information. The given string will be used in all the labels, but the variable part of the string will change with each label.
My question is: is it better to parse the strings one time, then store those values in arrays, or to parse the string each time a label is printed? Which will perform better? Which is better practice? What is the proper way to test something like this?

View 8 RepliesC# - Decompiling .Net Assembly Produces Code With Invalid Member Variable Names; Names Starting With $STATIC$?
Sep 5, 2011I am doing work for a client who has lost the source code for one of their VB.Net WinForms applications. The assembly they have is not obfuscated at all. I am trying to recover as much of the source as I can as C# source and have tried several tools for decompiling assemblies, including Reflector, ILSpy and JustDecompile (all the latest versions), but they all produce code with a huge number of errors in them. Because of the large number of errors in the generated code, I am going to ask about the specific errors (in different questions), get more directed answers and in this way try shed some light on why all the tools are having difficulty decompiling this assembly. This question pertains to the fact that the code generated by all these tools always have a large number of invalid member variables (fields) such as the following:
private short $STATIC$Report_Print$20211C1280B1$nHeight;
private ArrayList $STATIC$Report_Print$20211C1280B1$oColumnLefts;
private StaticLocalInitFlag $STATIC$Report_Print$20211C1280B1$oColumnLefts$Init;
why the generated code has these invalid member variables?

If , for exemple , the first line of listbox1 is already in the listbox2 then it delete the first line of listbox1 (listbox1.items.removeat(0)). And Do until listbox1.items.count = "0".

Get 2 / More Listboxes To Play Together?
Jun 2, 2010I have a program I'm trying to put together to allow my employees to submit shift reports. I'm doing this simply to make my life a little easier as this way, they will all be formatted the same. Instead of spending a large chunk of my afternoon thumbing through a bunch of differently formatted reports.
One feature that I need to figure out requires that one listbox can see what another is doing. Here, let me try to explain..
I have one list box that keeps track of EVERY action the employee does on a customers account. (cancel, upgrade, downgrade) and then a hidden listbox that JUST tracks "cancel" actions..one for "upgrade" actions and one for "downgrade" actions.
The reason behind that is that in the shift report, the all need to be listed separately. This way, I can just add each list to it's own array and list them where I need to.
The problem I've run into... If an employee handles an "upgrade" action at the beginning of the day..and then later on the upgrade is canceled, I can easily remove it from the main listbox that shows everything, however, I can't figure out how to find it in it's own listbox. The "Upgrade" box.

So unfortunately, on the shift report, it's still there even though it's gone in the program as far as the employee can see.The item in the main listbox doesn't have the same index as the item in each individual list boxes so I can't just tell it to remove the item at the same index..

Can User Copy Out Of Listboxes
Sep 16, 2009I've got my first ever program and it's working. Having tested it a bit it would be helpful for the user to be able to copy the results printed in a listbox into an email or text doc. Just somewhere where they can make a note of it really.Is there something I need to do to enable it? All the google results I found were referring more to doing this in code. I literally want to be able to support Ctrl+A, the Ctrl+C straight out of the program to wherever the user wants.
View 4 RepliesComparing Numbers In Listboxes?
Jun 5, 2011I am starting to feel completely dumb when it comes to VB.Net coding. I am using Visual Studio 2010 and am trying to compare the numbers in 2 listboxes. If an item from list A matches an item from list B, I want it to add that item to List C. Once it has added the item to List C, remove those searched items from list A & B. Continue until it runs out of numbers to check.

Datarelation Between A Datagridview And Listboxes?
Dec 17, 2008I have a datagridview (parent) and a (well, several) listboxes that I am trying to create a relation with.Datagrid has master records which contain ID fields to lookup tables. The lookup tables are populated into listboxes.I have 1 dataset which contains tables for my datagridview(s) and my listboxes.I need to create the relations so that when they click on a row in the grid, it shows the corrisponding item in the listboxes as well.Problem is, a lot of the ID's in the parent table are empty... so when I try to create the relation, it blows up.
Code: "This constraint cannot be enabled as not all values have corresponding parent values." I'm doing like like so
Code:
lo_relation = New DataRelation("RelationName",DataGridTableIDColumn, ListboxTableIDColumn)
I tried to reverse it, naming the ListboxTableColumn as the parent. That allows the relation to build, but I can't set the Listboxes .ValueMember to that...I'm kind of stumped... as it needs to be a two way relationship.
1) When the parent record (datagridview) changes, it changes the value in the listbox
2) When the Listbox changes, it changes the "value" in the parent datatable so it can be updated.
Would I resolve my issue if I populated the parent with a "default" ID in each field (say 0)... if the database value is null? And furthermore, populate each lookup table with a "blank" default value as well? i.e. First record is ID = 0, Desc = ''?
Drag And Drop Between More Than 2 Listboxes
Jan 8, 2010I've seen the code on this site to setup a drag-and-drop between 2 listboxes (and that works perfectly for me), but I have a need to be able to move items between up to 12 listboxes. For example, I move an item from listbox1 to listbox2; at some point in the future, I need to be able to move that same item from listbox2 to listbox3, then at another point in time from listbox3 back to listbox1, etc. When I make these moves, I need the item to be removed from its previous location. I've attempted to modify the 2-listbox code to include, on my test form, a third listbox, but that code copies to the third listbox, and when I attempt to move the item from the third listbox to the second, it, too, only copies and does not remove the item from listbox3.

Multiple Listboxes Not Working
Jan 30, 2012I have four list boxes, side by side. I've got a huge list of files that the program scans through and if (file insides) = (this) then; else if and etc. I know that part is working. The problem is actually the list boxes themselves. The reason I know this is:
I have four listboxes side by side, only the first one shows data, but if I delete the first one from the form, only the second will show data, if I delete first and second, the third one displays data, and if I delete the first three, the last one shows data. The problem is they wont display data at the same time. I was talking with someone else and they said I needed to change the IDs and I should see that option somewhere near the "Name" section. I use Visual Studio 2010... I don't see any IDs option to change. on how I can change this ID or maybe something I have to do to get these listboxes working?
