View 4 Repliescode snippet that would allow a progress bar to track the input of a text file? Normally I would not bother with this, but the text files are > 10,000 lines long, which is noticable even on a fast machine. The number of lines is variable, so I would assume that one would not use a fixed value to calculate when the progress bar goes 100%.

lets say I have a form (form1) with lables a-z which are all designed with default text "0". So they all show 0 on program startup. which is fine. I also have a dialog with 2 TextBoxes; I want my program to update the default text/value on (only)form1 labels x, y and z to whatever was put into the textboxes when i press the OK button on the Dialog, so these specified labels show the 'new' value on next startup. Is it even possible or should I save the values to a file which loads the values in the specified labels on startup?

View 10 RepliesI'm working on a little script to automate tasks across 12 servers, that are all on the same domain and have a similar setup. The tasks are to create a new folder, to then copy contents off the network into it, and to create a virtual directory in IIS 6 pointing to it. Ideally I'd like to log errors but that's a later concern. My approach was to write a VB Script to connect to WMI on each server in an array, then use it to run off a batch file. While the VBS works if I tell it to create a folder directly, it does not run (any part of) the batch file, nor give me any errors.[code]...
