View 1 RepliesI have a Windows Forms application. I am importing CSV files (from a website questionnaire) into a DataGridView.
I then need to populate the different columns in the DataGridView with the relevant information. A few people have filled in the Questionnaire incorrectly and I need to split the answers into the correct columns. I will give you an example -
Some people have filled 2 different e-mail addresses into the same answer. They are separated with a space, an equals sign and another space. One e-mail needs to go into one column and the other e-mail into another column.

I have a situation where data in a field contains CrLf characters. Code has been in place for a couple of years and many records have been affected.Should I add code to catch the CrLf characters at the field level?Should I add code to catch and possibly correct the data before it is uploaded to SQL?Should I modify the upload to catch CrLf characters and possibly correct the data in the upload procedure?Whichever approach is more appropriate, how do I identify CrLf characters and then correct it.

I have a multi line text box that accepts Enter and tab as input, but this data needs to be saved without these characters.

I need a similar function here.

If I set the Text property of a RTB to a string that has CrLf's in it, it seems the RTB reduces the CrLf's to a single character & screws up the positioning to set the SelectionStart property.So, for example, if I know the position of a character in the original string & I set the Selection Start value to that position, the selection highlighting will be off by 1 character if the start position is preceded by a CrLf & off by 2 characters if preceded by 2 CrLf's, etc.So how can I determine the correct position to specify my SelectionStart value?

I have the requirement to create an application that has multiple front ends developed using Windows Forms, WPF, ASP and Compact Framework Mobile Forms.I would like to be able to create a series of obejct representing the business logic and have this logic accessible from the various front ends available. My first thought was to use remoting as I'd like to be able to pass the business objects back and forth between client and server but the compact framework doesn't support remoting and also transferring a full framework business object to a compact framework business object doesn't seem possible.My next thought was to use web services but again the passing of business objects seems to be very hard to accomplish. Without doing this I would have to create individual web methods for each business operation.
Finally my next option is to use sockets and write the whole client/server logic within some classes and expose them to the UI/Business layer. My only problem with this is it is not scaleable should the number of clients increase dramatically whereas using remoting or web services I can host the solution via ASP.Net.Does anybody have an ideas on the best way forward for this or even have any input on how they would write an application that required a windows form, wpf, asp website and mobile device GUI all of which want to use the same business logic?
I output a text field with CrLf to an xml file and the textbox shows everything in just one line in the win app.
