I have a text file in c: as abc.txt which displays empid=e001, name=john, salary=5000 Now, we need to have a method which wil take empid as parameter and will find the line with the empid and create a text file with that line

I have two RichTextBox's; rtb1 and rtb2. I want to convert the contents of rtb1 to rtb2, but add a number at the start of each line.

I am trying to create an application to make self-extracting Exe's in Visual Studio 2010 Express. I would like to have a box in which files can be dropped into, then when you click "Compile" it will compress all files dropped into the box along with 3 others I must have delivered to this self-extracting exe. When the newly created exe is run, it will launch "Install.exe". I know there are other items out there to build the self-extracting exe's. I would however like to make my own that always delivers these 3 specific files along with whatever is dropped into the application.

View 3 RepliesI'm reading a text file with StreamReader, line by line. If a condition is met, then I do an operation and then start reading the file again from the first line. I realize I could close and then re-open the file, but surely this would be very slow.
I could do this easily in VB6, but pulling my hair out trying to do this in vB.net. It seems that 'Seek' is the function to use, but it doesn't work.
I've seen other examples, where it works, but you must open it a different way -- with a file number.

I am trying to extract text from a .pptx file. I am able to extract from all other shapes except a shape that is identified as a msoPicture to right click on this shape in powerpoint and ungroup it, but when I try to do this from code it tell me that the ungroup method only applied to group shapes.I did some research and found out that the msopicture shape comes from a .emf file but I don't have the least idea how to ungroup this shape or get the text from it through code.NB: When I right click on the shape in powerpoint and select ungroup a message box pops up saying "This is an imported picture, not a group. Do you want to convert it to a Microsoft Office drawing object?". But I cannot seem to find a way in code to convert this shape to Ms Office drawing object.

I have a csv file with 48 columns of data. I need to open this file, place it into a data structure and then search that data and present it in a DataRepeater.
