I have the html of a page loaded into a string.
confirmUse('??????','Eat'
I want to extract the number that the ?'s represent however confirmUse is used in other parts of the page. The only constant is the 'Eat' which is unique to this specific number.
I usually use Mid and Instr to find what I need but when I try to back track it gives me an error because the index number is below 0.
I was wondering something. Is it possible to call a function in a Dll whose location is placed in a variable?What I mean is that I create a string that contains the file location odll file(Dim str as String = "DllFileLocation") Then, I call a function from that dll. And thenI change the string to a different file name (str = DifferentDllFileLocation") and then call a function from that dll. Is that possible?This would be good for my program whereuserswould import their own dll files, and then the program would call functions from those dll files.

I am having trouble figuring out how to parse a string with delimiters. I have a text box which the user inputs data or what ever.

View 2 RepliesI have a text file with preferences in it. I read the file and find text on a particular line like this:If InStr(sLine, "avidDirectory") Then This is my line in the text file: avidDirectory "S:Avid MediaFiles" "D:Avid MediaFiles" "Z:Avid MediaFiles"..What I need to do is read each string between the quoations marks and place each one in a text box.I have 5 texts boxes to use if there are 5 different directories above (only three in the example above)So I guess I need to capture the text between the quotation marks, create a new string from it, and place that string into a text box [code]
View 1 RepliesI'll start off by saying I am using Visual Studio 2008 Standard. I am creating a program that will open installed programs using short code. For instance, if a user types in 'npp' then Notepad++ opens. I have it working just fine to respond to the predefined commands, but I would like to expand it so that the user can define their own settings simply by typing the program directory and the custom short code they want: Example: If I am an end user and would like to say define a short code for Windows Media Player, I would simply type the following: (Assuming Excel or likewise is used to open the csv file).

When building a class library which contains many classes, all classes uses a lot of common constants and functions, what is the best to do:
1- Declare these constants and functions as public in a module.
2- In each class declare constants and functions used by individual class as private.
The first choice is good for easy and fast implementation, but re-using a class in a different project will require importing the module to the other project.The second choice require a lot of copy/paste for code snippet but a class can be re-used in different project easily.

View 39 RepliesI'm migrating from VB6 to VB.NET, in hence my questions below:
I have to write a function that returns array of strings.
How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.
Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?
Say I have a List(Of Tag) with Tag being an object. One member of Tag, Tag.Description, is a string, and I want to make a comma-separated concatenation of the Description members.Is there an easier way to do this than to read the Description members into a List(Of String) and then use the Join function?

I'm creating a vb.net winforms application that will take in user given strings, parse them, and print out labels with variable information. The given string will be used in all the labels, but the variable part of the string will change with each label.
My question is: is it better to parse the strings one time, then store those values in arrays, or to parse the string each time a label is printed? Which will perform better? Which is better practice? What is the proper way to test something like this?
I successfully wrote a code to retrieve a version number from a HTML page which is this:
<div class="header">Latest Version: <span class="version">6.59</span></div>
So the following code will return the version number which currently is 6.59 which is what I'm after. [Code] But then i remembered that releases are done as following: 6.59, 6.59b, 6.59c, 6.60, 6.60b etc. So when the b version of 6.59 is released the parser will still return 6.59. So how can i make this code better?
After countless hours of searching I have been unable to get this code to work. If anyone can provide we with an alternative. I know the easiest way is to use the Split() function but im trying to do an alternative method by identifying the spaces within the string and splitting them up.

I'm trying to find a way to parse a string which looks like this:
1,394,7,0,0,0,0,0,,0,0,63,85,0,,0,0/2,595,59,8,0,0,0,0,0,,,0,0,,0,8,6,0/3,696,0,0,0,0,,,0,0,,84,0,0/#
So that it only reads the first two digits, then delete everything after that till it reads a "/", read the first two digits and delete everything up to the "/" again.This would result in this:
1,394
2,595
3,696
I don't know how to remove every character after the last of the first two digits up to the first / it reads, can anyone help me with that?How can I parse this code easily?
