I tried to modify the connectionstring as given below,But it also gave me "c:\Test.xls is not a valid path" error
connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\\Test.xls;Extended
If anybody had faced such problem earlier, Please let me know the solution implemented by you.
There is no such thing as a "tab delimitted XLS" file. A true XLS file is a binary format only natively readable by Excel, which your code will not work on. But, since you've said that you can open the file in Excel and export the data as a tab delimitted CSV file and your code suddenly work on that, leads me to believe that your initial file is not what you think it is.
As the previous poster stated, it looks like you're trying to import an excel file, rather than a tab delimited file (Excel workbooks have an '.xls' suffix whereas tab delimited are '.txt' by default). You can still open the workbook in the way you've started but you need to change the connection string. Have a look here[^] for details of what value to use.
ETA: you might need this one[^] instead depending on what version of Excel you're using.
If you don't have a solid enough foundation in encryption to know the answer you should not be writing code that does encryption, from a security standpoint. It is very easy to make mistakes that can compromise the data. If it is truly important information hire a specialist to come in for one day to do it for you or your company. If the data is not that important just do whatever is simplest and don't worry about it.
As for checking whether is exists in both languages. The documentation for both languages provide that answer.
As you can see I don't have a solid foundation in encryption, the data I am trying to encrypt is not so vital and sensitive. But it should be encrypted. I can even use Base64 but it would be a little bit too easy I guess.
I am trying to get a ToolStripPanel to have the same drawing style as the embedded ToolStrips, so that it looks like one continuous bar. I have the ToolStrips using the ToolStripProfessionalRenderer so that they are styled the same as the Windows Task Bar.
I have gotten close by creating a new Renderer derived from ToolStripProfessionalRenderer:
Hi, ive been using the Digital Persona SDK for past projects but for the scale of an upcoming project I am looking for a better SDK.
Has anyone had experience with different ones and which one would you recommend?
It doesnt need to be free.
