View 6 RepliesI got a little program that generates a random line of text from a .txt file and all is working well, at least for the most part.
On occasion I get an error message popup saying "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: Index."
Here's my code:

View 3 RepliesI've been looking through the FCL for a method that will allow me to erase a line of text from a text file and replace it with another line of text. Neither the StreamReader nor StreamWriter have a method for replacing or removing Text from a text file, as does the string object. Are there any available methods for erasing just certain lines of text from a file, and then replacing them with others?
In my code, I'd like to locate a certain line in the text file, and then at that point in the text file, use a For...Next Loop to replace each successive line of the text file with new text:
Dim user_data_file As String = "user_data.txt"
edit_input = New StreamReader(user_data_file)
Dim edit_line As String = edit_input.ReadLine
[CODE]...
However, I can't find any methods that will allow me to do this.
Shell(Application.StartupPath & "myfile.txt", vbMaximized Focus)The code above shows the error that the file does not exist. But it exists. I tried the same code for an .exe file it works great.!

View 7 Replies1.i want to open a text file in the exe.using Shell "mathtype.exe" "Filename" ' Assume file contains "Hai"
2.I have to copy the content "Hai".
3.I have to paste/write the copied content in a text file,
4.Save the text file in "c:"
Basically what I'm trying to do is read a text file line by line. After each line is read, it will put each line into a separate text box. I've been trying to do this for a while and so far I haven't been able to. I tried using a for loop, but that just put all my lines in to one textbox.
View 8 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.

View 6 RepliesI have to create a new program that reads to Text files. These text files are in the form of a report (with column headings). The purpose is to compare each record line by line to see if their have been any changes made. The record is based on an Account#. Over time these files will be considerably large. What is the best way to do compare records from each file. I'm thinking loading each file into an array and processing them that way.

as you can see in the code its supposed to read a text file and if the line contains the same string as in the textbox then its gonna make a messagebox.
now the problem, if the line does not contain the specific string but the next or any line other line does, then it should automatically read the next line on "Else" and that's where I'm lost
for a "Readnextline" command or something like that?
I have a list of random numbers in my text file.I read it like this.

Ok, I saw this code on the net

under the code I pasted at the top, but I get the text on line1 in all labels, like all labels become 1, while the text should be 1, 2, 3 and so on. So anyone can help me do that, each label gets the value of the next line in the txt file
the following code was to be entered to read each line of the file "line by line" It did not work for me as instructed and I am trying to understand why?

I've created a very basic WF Shell project which runs an EXE (xyz.exe) in the WF Shell project's Resource folder. I can get a command line working from the Shell to open the other EXE (xyz.exe). But, I can't get code to close the Shell project's other EXE (xyz.exe) once it is opened. The xyz.exe windows called by the Shell continues to stay open even if I pass a "close" command line to the Shell.
The following code (which Paul suggested in another posting) will not close the other (xyz.exe) EXE's running process (when called by the Shell). While the Shell seems to be able to return it's called subordinate EXE's (xyz.exe) ID, not sure how to use such an ID to close its process.
