View 3 RepliesI have the following condition
If InStr("a,b,c", stringA) > 0 OrElse (InStr("y,z", stringB) > 0 AndAlso value = 0) Then
endif
COndition 1 is false so i check for condition 2 that is "(InStr("y,z", stringB) > 0 AndAlso value = 0) "
What puzzles me is that when stringB is nothing it still falls into the if condition and executes the code.
On first look it would seem that when stringB is nothing condition2 would fail and as a result would not fall into the if condition.
for determining whether a string of data contains certain text, which is more efficient? I have read elsewhere that there is somewhat of a consensus to avoid legacy functions, since they may or may not be available in future versions.However, trying to use the contains method (or indexof equivalent of Instr) is causing me problems, I think, because I am having trouble performing a case-insensitive search.
I am trying to be efficient and functional in my code. I am reading an INI file, and I have preloaded the contents of the file into a String variable, for 2 reasons. 1) If I can test if a certain section exists in the code, I can avoid attempting to read a section of empty data (the INI reader class I have chosen returns the value or an empty string for a given request). More importantly, 2) I have created a data field that is not INI compliant (at least not to the API?) as it is a data field that can contain an arbitrary (unlimited?) amount of data which is a hex-encoded representation of serialized byte data. I need to be able to determine if this value exists in the file and retrieve it using normal string manipulation, since the INI handler will not pass strings longer than 256Chr.
So, the problem I am having is getting "strFileContents.Contains("data=")" to return true in the case where the file contains "Data=". This could be data=, DATA=, DaTa=, etc.Instr has the option "CompareMethod.Text" which, I believe, does a case insensitive text search. What is the equivalent for "Contains"?
I have a number of rewrite rules for a lot of things that I did in IIS7, like removing trailing slashes, canonnical URLs, lowercase lettering, and such. IIS altered my web.config, and everything works fine on the website, like it should. But in the Visual Studio web.config, the opening < rewrite > statement is underlined in blue, and at the bottom of VS, it says that the element 'system.webServer' has invalid child element 'rewrite'. But this is how IIS made it. I didn't do this manually. Should I be concerned with this VS error, or should I just leave as be, since it's working how it should work? Here's an example of my web.config:

View 4 RepliesI'm looking to do is scrub an html file for anything that resembles an IP address or any set of numbers for that matter. Normally what I would do is just using things like string.split to split out the html around areas that I want to search. What I am looking to do is be able to essentially search a large amount of characters for anything that matches this reg ex pattern.
Dim pattern As String = "^(d{1,2}|1dd|2[0-4]d|25[0-5]).(d{1,2}|1dd|2[0-4]d|25[0-5]).(d{1,2}|1dd|2[0-4]d|25[0-5]).(d{1,2}|1dd|2[0-4]d|25[0-5]):(d{1,4}|[0-5]dddd|[0-5]dddd|6[0-4]ddd|65[0-4]dd|655[0-2]d|6553[0-5])$"
'InStr' is a namespace and cannot be used as an expression.Dim FirstString As String = "me@me.com"

Is it possible to use a string for string 2? cuz whenever i tried it would return a 0 instead of the position of the string. however when i hard code the string into the code it works
View 7 RepliesI come from a C# background but am now working mostly with VB.Net. It seems to me that the above functions (and others - eg. UCase, LCase) etc. are carryovers from VB6 and before. Is the use of these functions frowned upon in VB.Net, or does it purely come down to personal preference?
View 4 RepliesWhat i am trying to do is take a character (which is going to be into a variable by user input) and search a string for this character, and save the positions of all character found and then change the same position of these characters in another string for the character that the user inputs. In other words, like a guess a word game. User tryes a guess, i search the string for that letter or number, if it's there replace it on the text box of the GUi, if not save it in another variable as a character that has been tried already, possibly an array.

I have an application in VB.NET which gets string data from the database. This string has data which looks as below:
"This is the update: I have an issue with the application"
I need only part of the data, that comes after the new line i.e. "I have an issue with the application".
For this I am trying to search the position using InStr where the string has data in a new line. I tried many options, but they don't work.
I used "vbCrLf", Chr(13), "
", "
", "<br/>", Environment.NewLine, but none of them work.
How can I get the data I need?
