Extract information from a video file?
View 5 RepliesI was looking for some stuff online, and i was looking through my reference sheets for vb.net, but it seems in the code i have found, there is declare in methods. Below is an example i am talking about. The thing is, that i dont recognize it and believe that it is an earlier version of Visual Basic ( 6 or earlier) which used it. Should i just keep looking for different code?

I've got an application that passes commands to a terminal window and saves all the output to a text file Here is one of the commands my application passes to the terminal
MyProcess.StandardInput.WriteLine("host " + device)
The output of which is
"HostA has address Y.Y.Y.Y"
this along with a whole bunch of other text is saved to a text file...my question is how do I find the sting "HostA has address Y.Y.Y.Y" in that text file and then extract the IP address and assign it as a string variable?

To simplify what I am trying to do, let's say I have a text file with only one line of data.
The data in this case is color info for one pixel:
Color [A=255, R=255, G=200, B=128]
What I am trying to do is read the text file and extract the hex color info and save them to their own variable.
So once the code has run, these should be the contents of the three variables.
RedData = 255
GreenData = 200
BlueData = 128

I have found the above code from the net and it works fine as I would expect. I know this because I have added a put the String StoreFile into a text box and it worked. From what I understand about the code above is that we are reading the file test.txt until we reach the end of the file and we are storing it into a string.
What I would like to do is either:
1. Search the String StoreFile until I find the text of my choice, and then extract the characters around it. See attached txt file.
For example, if I wanted to search for MNAUSD in the attached txt file, I want to grab the values on the line (highlighted in blue) and make them available to my program and ignore everything else.
"MNAUSD",UNITED STATES,US $,M,1.558850,1,1.369850,1.113500,L
I know these files are comma delimited, but I would rather use a regular expressions if possible as I have other files that are not comma delimited, so it would be ideal if I have a regular expressions to handle the search and extract
OR
2. Search the File test.txt LINE BY LINE, until I reach my search text MNAUSD and then extract the same values as above.

I am attempting to extract information about a work location from the IADsUser object. Other IADsUser methods like IADsUser::LastName or IADsUser: :EmailAddress return a string.I thought IADsUser::PostalAddresses returned a variant (array of strings) and I have attempted to extract the infromation, but I have had no success so far. I can find very little documentation on how to extract this information.I have provided some code below to try and make it clear what I am trying to do.[code]I am not sure how to print out objects properly in VB6. I am not concerned whether or not a particular IADsUser has the information I am looking for; I have error handlers in place to check for this. I removed them to make the code easier to read.

View 2 Repliesis there a way to extract all the text from a Word Document in VB.NET without actually openning the file? I'm asking since it is a very time and memory consuming operation to open a word document, select all, assign it to a variable and the close the file.I have a routine the opens all emails in a mailbox and analyses the body and subject object for regular expressions. I would like to do the same for the attachment, if it's in Word. if it's not possible to extract without openning the file, can anyone give me the best way to do it so that the routine doesn't destroy my server memorywise?
View 2 RepliesFor my database program, I need to open a text file and extract the numbers written there into arrays.
View 2 RepliesI have a relatively simple Listview that suddenly needs (due to new requirements) to have it's 'layout' extracted to a DataTable so that a common routine can convert it to an Excel spreadsheet for export purposes.The ItemTemplate is just a series of Table Rows with some text, data-bound labels and textboxes with validators in the cells.Usually, when trying to pull out a particular value (like what was entered into a text box), I use the ListViewItem's .FindControl method.
For Each objItem As ListViewItem In lvwOptions.Items
Dim objTextHrsLabor As TextBox = CType(objItem.FindControl("txtHrsOptByLabor"), TextBox)
decHours = CDec(objTextHrsLabor.Text)
Next
In this case, however, I'm trying to take all the data displayed - all the 'rows and columns' of the table that was created.Inside the ForEach / Next loop of ListViewItems, I started a ForEach/Next loop of Controls for each instance's controls but I got some really strange results returned (like controls that had a couple of table cells in them).
I get the sense I'm headed in the wrong direction. All I want is for the nicely-formatted 5-line, 6 column table to be converted to a 5-line, 6-column data table.
I am using Streamreader to read a text file containing data such as the following:
IN;SC;PU;PU;SP1;LT;VS10
IN;SC;PU;PU;SP1;LT;VS10
PW5;PU4179,27448;PD4179,29951;PD3244,29951;PD3244,30286;PD5494,30286;PD5494,29951;PD4555,29951;PD4555,27448;PD4179,27448;
The final goal is to use the numbers next to the PU and PD characters to perform specific calculations.
Essentially, I think the code needs to do the following:
1. Read each block of characters ending in a ";"
2. If the block commences with anything other than PU or PD, discard it
3. Extract the numbers in such a way that calculations can be performed. The following is an example:
x y
PU4179,27448;
PD4179,29951;
[Code]....
Essentially, there will be hundreds of these rows and I will need to sum up the deltas so that a specific formula can be applied.
I have tried doing this a number of ways but each seem very inefficient (using text boxes to store/swap data and creating additinal text files are 2 methods I have tried) and so I'm looking for some direction.
I need to load and parse a text file and extract data between points on any given line. I can load the file, but it's the parsing that's giving me headaches. e.g. "Phoned Jim and arranged for John to attend site" First I need to search for "Phoned" because the line always starts with that, and then I need to extract "Jim and arranged for John"
