View 3 RepliesI'm having trouble figuring out the logic to this problem:Thus, you can create the bar graph with each store's name, and a separate label that has the sales information for each store. Since each asterisk represents $100 sales, you can just do # of sales mod 100 to get the number of asterisks you need for that store, then loop and add asterisks until the label has the correct number of asterisks. Repeat for each store input that the user gives.

View 1 RepliesI have a very large text file about 4 million lines that I would like to separate into several small text files based on the strings contained in the first column of the text file. I want to open the large text file, choose the lines that apply, create a new text file with a name that has a number at the end of which will match up with the value in the first column of the text file. I want to then copy the applicable lines to the new small text file, save and close it. I'm not sure how to go about doing this after opening the large text file and using the readline method. What if the folder does not exist? Do we have to create it? I want this procedure to be general, as there could be up to 25 million lines in the text file.

View 1 RepliesI am trying to create a log file which I am going to use to populate some controls (DataGridView or Treeview). I am trying to figure out if should use text files or XML files to do so. Effectively the log will highlight multiple phases in a client-side app. The log will be written to at various phases when the project is running. The user will always have the options move on to the next phase or save progress and exit the project. As such, I want the log file to highlight how far the user has progressed throught the various phases AND I want the log to highlight varous information from each phase. Whenever the user starts the project, they will be given the option to load existing log files. So the project will have to read these log files and append them where necessary as the user progresses.
I am not sure what the best way to do this is and below is a rudimentary approach using text files. As you can see, the top of the file would have a summary of all the phases and whether or not the user completed each phase. Next each phase would have a data section highlighting what data was stored along the way. I have used a ":" to denote each section. Then within each section I would obviously need to use a delimeter for all my data. So if Phase1 = True, then I would load all the pertinent data from "Phase1:" into the desired control. Can anyone provide an efficient way of doing this and provide some insight as to whether I should use XML instead. The phases my change during development and I am not sure yet which controls I will be using. Does XML provide more flexibility.
In summary I am looking to create, read/write and append log files and populate controls with the data in varous sections of the log file. Example:
Phase1 = True
Phase2 = True
Phase3 = False
Phase4 = False

I need to be able to take an MP3 or WAV file and plot a graph of its waveform over time. Prefferably without playing it first. The representation doesn't have to be amazingly accurate as it's not for EQ purposes. I just need to pinpoint certain points in the MP3 / WAV when specific music / sounds etc occur (similar to the display in Windows Sound Recorder).
how I can go about that, or if it's even possible in VB 2005?
