number = 4
length = 7

Now I want to read it in a format that it will check the string 'number' or 'length' or 'force' or whatever and stores this data into specified arrays or listboxes. Like a force() array or listboxforce.items()
What I am trying to do may be better for use with SQL Server but I have seen many applications in the past that simply work on text files and I am wanting to try to imitate the same behaviour that those applications follow. I have a list of URL's in a text file. This is simple enough to open and read line by line, but how can I store additional data from the file and query the data?
E.g.
Text File:
link1 - 0
link2 - 0
link3 - 1
link4 - 0
link5 - 1
Then I will read the data with:
Private Sub ButtonX2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonX2.Click
OpenFileDialog1.Filter = "*txt Text Files|*.txt"
If OpenFileDialog1.ShowDialog() = DialogResult.OK Then
Dim AllText As String = My.Computer.FileSystem.ReadAllText(OpenFileDialog1.FileName)
Dim Lines() = Split(AllText, vbCrLf)
[Code] .....
Am I going completely the wrong way about storing the data after importing from a text file?
I have a list of files and all of them have a different size. I need to upload them in chunks of 250Kb (or less if it's a small file or if it's the last chunk of a file).What I would like to do is read a bunch of chunks (lets say 15 chunks), in a separate thread, and then store the chunks of data in some sort of list. This list must be available to other threads.
An upload thread (I don't need help with uploading itself) takes the first chunk from the list and marks the chunk as "currently being uploaded". When the chunk has been fully uploaded, then the chunk is removed from the list. A second upload thread takes the next available chunk in the list that has not been set to "currently being uploaded", etc. There are a total of 10 upload threads working at the same time.
As soon as a chunk is removed from the list, then a new chunk of data is read and added to the list.Does anybody know what kind of list I need or how I should do something like this? I don't expect people to write out the code for me, but I have no idea where to start with this.
I have developed a vb.net dll (.net 3.5) which does the following :
- I have data of several stock market companies.
- They are stored in several folders under a main folder.
- These files are random access files.
- There can be around 4000 files in total for example.
I wrote a program which reads a current csv file and stores contents in array. Then I store name and path of companies in folders (which I was talking about). Then I match one company from csv (stored in array) to companies in user's folder (again reading from array). If found I insert data in the file (random access file). This whole process takes for eg. 2 min my system. A similar program was written years ago by someone in powerbasic which takes slight less time if run one but if run for multiple csv files it takes only a few seconds doing the same thing for other files. When I do the same thing (by writing code to .net dll) and making a dummy app to run it, no matter how many times I run it takes same time. And is way slower than the earlier one (PB) one I was talking about. But if I paste the same code in my win (.net) app and not use .net dll then it runs a bit faster.
I need to show status so if I pass my form's label reference to .net dll and it updates it does that slow down process a lot. As I mentioned I am trying to process the files and it takes longer in .net. What should I do to get best performance? Unfortunately due to unexplainable reasons I cannot change the format or use a db. The files which I am reading/writing (random access files) are use by other products so I have to stick to that format. What I am doing is storing the location of those files in array so that I don't have to search folder again. that is not taking time. But opening reading and writing files is time consuming if I am doing it for few thousand of them. A similar program in powerbasic (developed years ago) runs fast. Running code thru .net dll is slower than running it thru program. Why?
I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

My text file is a settings file and I know I will be adding more to it in the future, right now it reads "autoplay=false;mintray=false;"I am currently using probably the most inefficient way to check both of those settings:
if contents = "autoplay=false;mintray=false;" then
elseif contents = "autoplay=false;mintray=true;" then
elseif contents = "autoplay=true;mintray=false;" true
elseif contents = "autoplay=true;mintray=true;"
endif
How can I read the file, find each word from the equals sign to the semicolon, and store each of them in a variable identified by the text before the equals sign? Something like this:
contents = "autoplay=false;mintray=false;"
autoplay = "false"
mintray = "false"
Also, how can I edit the settings in the text file without having to overwrite everything every time I save to it? For instance; finding mintray in the text file, and changing mintray to true instead of overwriting the file with "autoplay=false;mintray=true;".
This is my current

View 1 RepliesI have to text file in the following format :

I want to get all the words before the tab into one array or to create a new text file and the all the words after the tab into another array or create a new text file too.
Here my function to get the words before tab into an array :

I wrote the above function to get all words before tab but I got all the words into array. I've been trying to use the Split method above. What is another method to split those words ?
I know this can be done with regular expression but I don't know regex yet. If you can show me how to get this done with regex it'll be awesome.

For my website I've just implemented tinyMCE for my site (just a word processor). Everything works fine except when i try to store the string variable input into a sql server database. I want to store a string and not have the html tags make me exceed the 8000 length limit(the html tags take up most of that space). My question is, is there a solution so I can store my document with the html tags without shortening my document? Create an if statement that will determine the length If > 8000 than split the string apart and insert into separate fields. Maybe their is a compression feature which I'm unaware of?
