I need to add an additional dimesion to outputArrayOfBits() in the code below which I hope conveys my intention. I need to convert a one dimensional array of 1 to n boolean (bit) values into arrays that group them by 8's so the output can be consumed by someone needing these values to be in hex format (0000 1111) = 0F How do I change the declaration of 'outputArrayOfBits and the nested control loop to achieve that?
Dim inputArrayOfBits As New BitArray(32, True) ' I can't change this.
'Create array of bytes containing what will be sent out has hex numbers 0 - F
'outputArrayOfBits(0) = (1,1,1,1,1,1,1,1) 'Hex value FF

I am trying to extract some data from a website using a LINQ statement, the XML is in the following form.
<parent>
<p>
<b>
Title
</b>
[code]....
I would like to get the As Of Date and Data (the data row is iterated several times). Also the table and as of date appear several times in the document (the table is active from a date).I can get the rows using the following LINQ but how do I get the As Of Date
Dim l_PricesTable = From rows In l_Xml.Descendants("tr") _
Where ((rows.Descendants("td") IsNot Nothing) AndAlso (rows.Descendants("td").Count >= 1)) _
Select Data = rows.Descendants("td")(0).Value,
AsOfDate = ???
I have no way of changing the XML as it is a 3rd party source. There is no XML element which contains just the as of date and also the table, they are all under the one parent node.
I have address data that is surrounded by random text. Is there a way to extract this data either with a call to a web service or some vb.net function?

View 2 Repliesi have been searching the web for days and yet to find a clue on how to extract specific data from a flat file, i know how to extract all the data from flat file but not "specific data".
my problem now is that i need to extract a certain data out from a very very messy log file, what i need is to extract the decimal data right after "score=". it is in this format "score=1.938249".
for the decimal data right after "score", it is very random, there is no fix length to this. and also "score" does not fix in a specific position, it could be starting of the string or ending of the string of messy data.
just a peak on my messy data,

If I don't do a display I can generate about 20,000 data per second, but if I do, I get about ~9,000 data per second.
PS. Since the generating logic in is a thread, I have a function that does the displaying to the label.

I am pulling different information from the same file at two different times: 1) The first time, I pull information that is inserted into a combobox. I need to use the combobox as a filter for when I pull the information a second time. 2) I pull different information from the same file, and it is outputted into a datagridview table. I already have a filter in place when the information is pulled the second time, and I was wondering if I could add to that filter or if I have to make another filter? The filter (or filters) will be used to filter the information in the datagridview before it is outputted in a chart.
This is the code for binding the combobox to the information

I need to make a custom control and decided, before that, to see if there were any additional components that I could utilize.When looking through the list, I found a component called an Expander. So I decided to add it and see how it works.
After adding it, I couldn't find it at all within the toolbox. I went back to Choose Items and it was checked, but still not in the toolbox.It's probably important to note that it is a WPF component and this is not a WPF Project. Would that make a difference?Is there something else I may be doing wrong?

View 9 RepliesCan a BackgroundWorker call additional subs? In my program I am connectiong to an OPC Server. I am doing some AsynReads, which in themselves don't take anytime. But Once I get the AsyncReadComplete returned, I want to do the AsyncRead right away. Basically I need to Loop them. The problem now is that while it is doing this, Everything is unresponsive, because it is just going through the loop. So to perhaps rephrase the question, If the BackgroundWorker initiates a process (in this case AsyncRed) would the returned AsyncReadComplete be apart of the BackgroundWorker or seperate Thread?

The application itself (Form1) is a small box with dimensions of 442x306 that will open even smaller forms on top of itself. Right now, I have everything positioned to open in the center of the screen so, in theory, everything works/looks fine as long as the user doesn't move Form1 anywhere.
View 15 RepliesSo, I wrote a loader that extracts an executable that I have stored as an embedded resource. It writes it to %TEMP%my.exe.I made my.exe extract some files on launch. Thats why I made it in the temp. But the problem is, when I do Shell(my.exe) to the temp dir in the loader, it runs ok. But the files execute to where my loader is. :S
I was expecting the files to be extracted WITH the my.exe in temp. So if ran on my Desktop, i'd get all these files, as with putting it in temp, it'd work a lot better.Any idea how to get my.exe to launch and not put files from my.exe to extract to the loader's launch dir?
