View 3 RepliesI have a really modular application in which modules interact with each other for many, many tasks. Lately I have been making some changes to fix some bugs and some processes are now taking longer (not making the application unusable though).I now want to log the times it takes to perform each action, also taking into account interactions with other objects, to identify where is it taking long. This logging code would most likely be temporary. So, the question is: How can I write all these actions's latencies (or timeStarted and TimeEnded perhaps) to a single file from all the objects?

I'm working on something whereby I write and read alot of data to disk directly as bytes. But I can't figure out a foolproof way of delineating data structures chained in a single file. A null byte obviously wouldn't cut it, because that could occur within the data structures themselves. Theoretically, any pattern of bytes can potentially occur within a data structure. Does anyone have any ideas for a byte pattern that I could use as a flag for my streamreader? Anything reasonably short, since it's going to be pretty complex, streaming through each file twice, once byte by byte to find the flags and again to split the stream.

View 5 RepliesI have an issue where I need to load a fixed-length file. Process some of the fields, generate a few others, and finally output a new file. The difficult part is that the file is of part numbers and some of the products are superceded by other products (which can also be superceded). What I need to do is follow the superceded trail to get information I need to replace some of the fields in the row I am looking at. So how can I best handle about 200000 lines from a file and the need to move up and down within the given products? I thought about using a collection to hold the data or a dataset, but I just don't think this is the right way.[code]....

I wrote a file and I am getting double files.... My Loop executes when its equal to what I want to change it starts my sub procedure which copies the new information into the temp file. It would be there if it then went back to the end of the loop and continued however its going back to the loop and putting in the old information that I changed from. So then I get a duplicate name with different records.
Dim fmtStr2 As String = "{0, -16} {1, -10}{2, -14}{3, -14}{4, -11}" 'format by zones

How can i create this ? i want trying with data set but getting problem
I am having problems writing correct data to a file. I create a string of characters (approx 5000 bytes long). The string is a mixture of text characters and numbers converted to bytes. I then:
a) write the string to a readable text file
b) display the string contents to the console
c) write the string to a file - BDF.bin (I tried both IO.BinaryWriter and IO.StreamWriter but get the same error)
The byte pattern for the text readable file and the data displayed on the console match and for the most part , data bytes in the StreamWriter file are correct (first 4096 bytes are OK) but there are some extra bytes and some wrong bytes.Here is a comparison of byte patterns (hex values character written to the file) starting at byte 4096
Console: 45 44 52 31 00 00 00 00 01 00 00 00 90 01 00 00
Binary File: 45 44 52 31 00 00 00 00 01 00 00 00 C2 90 01 00
The byte patterns match, however in the binary file, there is an extra byte (C2).To display the console data, I read one character at a time from the string and display it using hex(asc(mid(string,i,1)))I view the binary data in the BDF.bin file using a hex editor program. I even tried 2 other hex editors and all showed the same byte info.
