VS 2008 Sting To Int From Array?
Oct 5, 2008
i'm stuck on something so easy, i've googled, tired various methods but cant get it to work. Imagine if you can, i have an array (set as a string type) but the second slot holds a numebr that i want, e.g. 2333.
So to grab it i use the following code, however as my sport array is set to a string it wont allow it. Like i said i have tried a few ways but nothing works. Such a stupid and simple situation. I'm much much better with actionscript surely its just a string to int conversion?

This problem I guess is easy to solve for an "RegEx" master :P
My string look like this:
"name":"stefanACM".id...
"name":"test1".id...
"name":"test2".id...
So I need RegEx to get only names from sting (stefanACM,test1,test2). That means I need RegEx to find string between "name":" and ".id

string which is obtained from a webservice that I would like to display in a textbox. The problem is the existing string is in HTML format so when I place it in the textbox it still has all the <Tags> etc. Is there a way to parse this text or would I be best to use the webbrowser tool? (I want to stick
with a textbox if I can)

This is my first time working with VB, though I've been working with VBA for a couple years now to automate office routines at my work. At my last job, I saved about 3 hours a day with my automations, and at my current job, I'm shooting for about the same. The problem is, though I have a high affinity for computers and technology, I never studied to be a programmer, and so I really can only tweak code I find online, and then eventually build up enough of my own subroutines to accomplish the tasks at hand. This is why I'm posting here on this forum, I've reached my wits end for what I imagine is a relatively simple problem. This was initially written in VB 6, but I imported and converted it with Visual Studio 2008, and it runs fine. This demo code is set to populate a PDFwith some sample string text. What I want to do is to replace the string text with a reference to data in either an Access or SQL database - I prefer Access, but either will work. Here is a sample of the demo code I'm working with:
[code]...
On this last line, I want to replace the "1" sting text with a reference to a temporary 1-row table I'll be generating from an Access Query, with Field Names to match the Form Field names of the PDF, So I've setup an Access DB with the following configuration (in reference to the path, I'm using Vista x64):
[code]...
I have also imported this table as a dataset (my understanding is that the import into Visual Studio 2008 makes it a typed dataset?) so either referencing the access DB directly or the imported Dataset should work. I can also setup the Access DB as a SQL DB instead if it would make it easier. Now, if I was programming in VBA, I might do something like this:

I am trying to test certain cell values to see if they contain subtrings of a certain format at the END of the cell sting value.E.G.I have cells with the values...
324f5
346-ssth
4565-Q1-09
dsfsd46
[code].....
I want to run a macro that searches through the cells and tests to see if they have a substring sitting at the end of the value that is in the format "-Q[number]-[number][number]" OR "-[3 LETTER MONTH ABBREVIATION][number]-[number][number]" OR "-[3 LETTER MONTH ABBREVIATION][number][number]-[number][number]"and then if the test is true, the cell color is changed to RED.So if I ran the macro on the example I gave above, it would turn the cells with the following values red:
4565-Q1-09
454354-FEB2-09
546-5-MAR03-09
I can do all the VB side of things but I don't know Regex but know it would help. I'm in a bit of a rush to finish this job for work because I finish working here in 2 days and need to get it done before I leave!

I have an assignment, and one of the requirements are to take a list of colors in an array and determine which letter, of the first letters of every color in the array, appears the most. (Essentially the mode, if converted to numerical values).

I have 2 arrays, tile(13,6) and loc1tile(13,6). Is there a way to make the values in loc1tile(13,6) equal to the corresponding values of tile(13,6)?Do I have to do it like this?
loc1tile(0,0) = tile (0,0)
loc1tile(0,1) = tile (0,1)
loc1tile(0,2) = tile (0,2)

I am writing a scripting language which used .net for execution. Now I have written a function which accepts an object and return a set of numeric values. I wanted user to pass any numeric array (e.g. integer,single,double,long) and I could return values in that format. I mean user can retrieve value in any numeric array type rather than specifying an array type. E.g.

I am trying to create the following program Store in a 1d array a set of 5 place names and in a 2d array the distances between the places. Ensure that the order of the places is the same in both arrays. When the names are places are input the distance between them is displayed. If they are not both in the table a suitable message is displayed
Dim town(1 To 5) As String
Dim Dist(1 To 5, 1 To 5) As Integer
Dim First As Integer
[CODE]......................
I think the best way forward is pass a parameter to the function findnumber.

I have a string containing many lines. Each line has many values separated by commas. Basically it's in CSV format. The number of lines is variable but the number of columns is always 7.
I can get each line into a one dimensional array using Split(Var, Chr(10)).
I'd like to make it a two dimensional array where the second dimension contains each comma separated value.
I've got
Dim VarArray1() As String = Split(VarText, Chr(10))
Dim VaryArray2(0 To VarArray1.Length - 1, 0 To 6) As String
Is there a quick way to get the contents of VarArray1 into VarArray2. I know I can do the following.
For Counter = 0 to VarArray1.Length - 1
Dim line as string = VarArray1(Counter)
Dim Values() as string = Split(line, ",")
For Counter2 = 0 to 6
VarArray2(Counter,Counter2) = Values(Counter2)
Next Counter2
Next Counter
But is there a quicker way to do it that doesn't require passing through each element of VarArray1 and then passing through each element of Values.
The eventual goal in all of this will be to find the highest value in the 3rd column (the arrays are strings at this point because not all columns are numeric). To do that once I get the values into VarArray2 I suspect I have to pass through each element VarArray2, i.e. VarArray2(Counter,2). Unless I can copy the whole third column into a SortedList?

when I copied my project and brought it to a lab at school, the code works perfectly. Looks like I have a broken install at home, or perhaps some permission issue.I'm working on a homework assignment. It requires, among other things, that I create a program to read the contents of a text file, write them to an array with an upper-bound of 50, and if is full before the text file is exhausted, to increase the upper-bound by 10. Finally, the program must output the contents of the array into a list-box.Unfortunately, while my program successfully updates the upper-bound, any attempt to output the contents of the array causes an error stating the content of the array is null. Obviously I'm running into an issue when I ReDim the array!

This code works fine except it does not pick up the last word at the end of the line. The text file it reads, words are seperated by tabs. When running this code it picks up every word except for the last and chucks it in the array, any ideas to find out how to get the last word placed in the array.
Do Until strStudent Is Nothing
' this will run through the read line function until it finds the end of the whole file itself
For j = 1 To Len(strStudent)
' this will read through the entire line itself
ochar = Mid(strStudent, j, 1)

I am having an issue with my coding. I believe that this is correct, but when I try to load the form it results in an error. I am trying to load each individual line of the Cat1.txt file into the wordsarray that I have declared publicly because I will use the array in other subs. When I try this, I get a runtime error that states "NullReferenceException was unhandled." Is there a better way to code this? Also, how could I exclude the first line of the text file from the array?

I used an array for collecting data throughout my program. With "Redim Preserve" I increase the size along the way. However I understand that this method is not really efficient and recommended is to use: List
So I tried (simplified here):

But the line: "ExtInfo(indx).Done = True" produces an error: "Expression is a value and therefore cannot be the target of an assignment."Clearly I don't understand fully the concept of "List(Of T)"...

I'm fairly inexperienced with VB but have been trying to get "save" functionality out of a program I'm trying to write. Basically I have a Datagridview and I want to write each line from the grid into a .txt file. So what I've been trying to do is use Datagridview.Items and then variables as column / row indexes to move cell by cell left to right , writing each cells data to an array which also increments along the way. Then using WriteLine to write the array to the text file, zero'ing all the counters then starting all over again for the next row.... make sense?
