View 5 RepliesIn my windows application, I want to check which part of code (or routine) has caused un-handled exception event to occur from application events in its running mode (not debugging).
If this is possible then please guide me how to do this.
If any clarification regarding this is required,
What is the code that I can use to describe what happens when there is not just one exception in a'Try...Catch..Finally...End Try' statement? For example: 'Catch' is used to describe what happens when a certain exception occurs, but what can I use to describe what happens when a certain exception does NOT occur?

Still getting to grips with regex and have seen a few samples about that give me most of what I need so asking for opinion on this. I need to extract x words from a single line, so the regex could use w+ to get characters, however my line may contain anything inside the word like:

I am using WebBrowser1.DocumentText to get a websites source code, and then parse a string. I am trying to view the source line by line, and doing it as follows:
[Code]...
However what is displayed is each character from the source code, rather than the line. I am making the client log into a website, and the needed value from the source code is then parsed, so I need to use the WebBrowser type to get the source code.
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"

View 6 RepliesIn my project, I have a local dataset (XSD) that I am using as local-temporary tables. I am getting a System.InvalidCastException when trying to access the field in one the tables. I believe this is because I my code is (incorrectly) not setting a field's value in a row before trying to access it.My problem is that the exception is breaking in the designer file and not in my code. As a result, I'm having difficulting determining which line of my code reading the field value before it has been set. Is there any way to configure Visual Studio to break in my code instead of in the designer created file?
View 1 RepliesThis may take some explaining but the concept is pretty simple. A user will select a file which contains data that they wish to extract from, so keeping it simple they pick a file like so:
[Code]....
So, I need to show the user the file, allow them to select a line to match and/or extract from. So they select the first line ready for a match, they then select a word/s to mark as a constant for matching, so in this case it would be: MyGroup A simple version for text match would be like "MyGroup *" Now, I need to convert this to regex dynamically (I assume its the best method), its not a one off, the data that is selected is all open and up to user selection. There could be multiple selections and multiple extractions on the same line!

I have an application and I want to use the "Line Numbers" to error catch.
So how do you call the line number of the exception?
I've got some code which errors and I'm using the stacktrace to find out what the line number is but it seems to be giving me the wrong number
[Code]...
It seems to give me the line number of where the StackTrace is starting rather than the line number of what is causing the exception
