View 1 RepliesI am trying to save details from my program into a sort of mini database using excel, my program isnt having a problem opening the excel file, it is having trouble inputting the data. The first problem i would like help with is maybe a loop of some sort to get my program to look through each line on my excel spreadsheet and find the next empty line so it can input the data.
I was having some help from another person who gave me some code which go's to the very bottom cell and goes up until it finds text and then off sets by 1. However this was in the form of a macro, and I need a way to do it from my program.

I'm currently developing an app which essentially needs a way for me to search in a text box or file for a specific string, and extract the line on which that string appears on. It will be unique, and the syntax is the same on each line. It has basically 2 ID numbers, and is laid out like this:
123456|123456
So, I'd need to search for the first part before the |, and then get the line so I can get the bit after the |, which is the important bit for me.
what i need to do is open a txt file, read line by line, decode each line into an array and display. Now all works ok apart from one line.
sTextLine = objReader.ReadLine() <-- Value of string cannot be converted.

I'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 using asp.net oledb to export information to excel file. I encounter problems when the information to export becomes too big, in this case the code I have given below, the excel file generated becomes an empty spreadsheet.If I changed the loop to 1123 for insertion of the rows. The generated excel file is fine, 1125 rows, and 4 columns shown.A test program in windows form is also working fine regardless of how many rows.[code]I couldn't find a solution to my problem as well. What I did eventually was to run the process using another separate windows service. The code works perfectly fine running from a windows form or service program, but not asp.net, not sure why.

It even indicates if the string I'm seeking is in the middle of a line. But what I would like is for the routine to highlight the line that that string is in and ensure visible. I can do that with another routine that uses an integer, but then the whole string(line) has to be the searchString. I've tried combining the two and even calling a Private Sub but with no success:(What is the best way to do this? Also, how do you get around doing it when the searchWord in in several lines?

View 10 RepliesI'm trying to read an .rtf file one line at a time but I'm clearly missing something!The file contains 3 lines and I want each line to end-up in a different RichTextBox, so:
Open File
RichTextBox1 = 1st Line in File
RichTextBox2 = 2nd Line in File
RichTextBox3 = 3rd Line in File
Close File
What am I not understanding? I've tried using LoadFile to load the whole file into another RichTextBox first as I got the impression that RichTextBoxes are indexed - but what I got was strings not .rtf format. I've also looked to see if there's an equivalent of the text-centric ".ReadLine" and nothing seems to fit the bill.
