Move Through Array In Reverse Using Loop And Not For?

Mar 27, 2010

I'm in a pickle... either that or it's getting too late in the day. How do I loop through an array in reverse without using FOR?I have an array of string values, I need to loop through these values until I find the first instance of a value then stop. I have considered a sort on the array but each query would need me to sort it accordingly (the data in the array has many instances of the strings within strings I am looking for, e.g. there could be several 'to' but I need the first, there could be several 'from' but i need the last)When I find the instance of the string, I then need to grab specific data from that string.

I hope that I'm not just overlooking something, but I am really struggling with working with an array. To simplify my issue: Suppose you type out the values: 1 through 5 into a textbox (1 2 3 4 5). I'm looking to convert that string to an array, so that I can reverse the order and then show the new order in the textbox.

Move To Next Item A For Each Loop?

May 6, 2009

Is there a statment like Exit For, except instead of exiting the loop it just moves to the next item.[code]...

Just wondering if there is a way to jump to the next item in the Items List. Im sure most will proberly be asking why not ust use the else statment, but to me wrapping the "Do Something" code seems to be less readable especcially, when there is a lot more code.

Move The All "Redim" Statements Outside The Loop?

Jan 15, 2010

I am using Visual Studio .Net 2008. I am using "Structure" statement for my work. It is working with me perfectly. I am not sure if Understand the structure statement very well because it does give me wrong answer if I change the position of "Redim" of the structure elements. My problem is the structure is using "Redim" in many places which is a dangerous procedure. I do not know how exactly to explain my problem because the structure in my code is used widely and called in many subroutines. I will try to explain with the below simple code:

[code]...

My question is: How can I move the all "Redim" statements outside the loop so that the Redim happens only ones? What does "TheCollection(Iteration + NumberOfMembers).TheResult" does take? Is it zero or what?I searched the web but I could not find a proper website or article which explains the structure. The only useful link I found is this:[url]

VS 2008 UI Threading - Move/interact With Both Forms While The Loop Is Running ?

Oct 17, 2009

When it comes to threading. I've managed to adapt one of JMcIllhinney's backgroundworker codebank examples to somewhat suit my needs, but not completely. I have a main form, and a second form that appears while I'm running through a for loop. It informs the user what is currently happening. I set up a backgroundworker that allowed me to continue to use the main form during the for loop, but the other "status" form was completely frozen, and any labels or graphics were shown as white boxes. I am struggling to figure out how to be able to move/interact with both forms while the loop is running.

[2008] Move Bytes In Array?

Feb 2, 2009

I need to move bytes in byte array.

Dim data() As Byte = {&HE4, &H96, &HA3, &H47, &H42, &H4A, &H80, &H90}

I need to make so that the first two bytes would be deleted and the rest moved to the first one's for example:

Delete: E4, 96

Move: A3 and all the rest to the place where E4 was. (|A3 = 0|,|47 = 1| etc.)

In C++ it's possible to do it like that:
unsigned char data[]={0xE4, 0x96, 0xA3, 0x47, 0x42, 0x4A, 0x80, 0x90};
data+=2;

how to do this in VB.Net without making a new byte array and then using a loop to put the all bytes in that place - it would be too long and would use more resources.

Foreach - Each Loop On A 2D Array In .NET

Oct 14, 2011

I'm writing a loop to go through the first array of a 2D loop, and I currently have it like this:

For Each Dir_path In MasterIndex(, 0)
'do some stuff here
Next

But it's giving me an error, saying it expects an expression in the first field. But that's what I'm trying to do, loop through the first field. How do I fix this? What would I put in there?

EDIT: to clarify, I'm specifically looking for the 0th element in the subarray of each array, that's why that second field is constantly 0.
