Single File To Multiple Subdirectories?
Jun 7, 2009basically im looking to have two textboxs with 3 buttons
TextBox1.text contains the path to the new file and
TextBox2.text contains the path folder to subdirectories
i have everything i need working, haha i know not much, this is only my second day with vb.I just needed a button now to carry out the function of copying the file i tried using simple file copy but i had to specify a file output in that and it only gave me option to copy it to one directory.For instance
C:index.php TextBox1.text <- loaded in from button 1
C:www* TextBox2.text <- button 2 loading subdirs
now i need a button 3 that would carry out the function of copying textbox1.text to all subdirs in textbox2.text.i thought i would have been able to use simple copy as stated above with wildcard in my program but no joy

File I/O And Registry :: Filename Currently Being Used By Another Process
Jun 11, 2009I get the common error: " 'File Name' is currently being used by another process..."
My problem is that I have two forms. If the file doesn't exist in the one then it creates the file and opens up the other form, if the file exists it doesn't do anything, however, in the other form that it opens up I have it "attempting" to write text via StreamWriter. But my problem occurs when the StreamWriter tries to open the file for writing, that is when the program tells me that the file is currently being used by the other process.
In my first form I close the form via Form.Close and all I am using to create the file is System.IO.File.Create. Now I know that the System.IO.File.Create is causing the error because I have this process checking the very first thing on the program load. I am trying to find a work around the System.IO.File.Create but no luck here... I am trying to create a .txt ... lets say test.txt .

View 6 RepliesFile I/O And Registry :: Finding Path/filename Associated With Extension?
Jun 24, 2011I suppose technically this isn't .NET specific but I suspect this is something to do with the registry and I'm using .NET!I'm trying to find out how to get the fully qualified path relating to a file type.For example, the system knows that to open a PDF file it needs to launch C:Program FilesAdobeAdobe Reader 10.0Readeracrord32.exe
I've had a good long search through the registry and found a lot of references to the adobe path probably too many - and I've edited them to try and "break" the process so I can identify which one is used to discover the path but with no luck. I'm assuming this has something to do with HKEY_CLASSES_ROOT?
File I/O And Registry :: Reading Multiple Keys From The Registry?
Aug 27, 2008I am writing an application that connects to a specific com port. This com port can change depending on how many physical ports are on the PC, and if other USB devices have installed com ports before this one.
I have the communication to the com port all working great, but I need to get the com port description not just the "COM#" which is all I currently get.
I found in the registry where the description is stored but am having trouble doing what I need.
In this key:
Code:
HKEY_LOCAL_MACHINESYSTEMControlSet001ControlClass{4D36E978-E325-11CE-BFC1-08002BE10318}
there is a varied number of sub keys. The are numbered 0000-NNNN depending on how many ports you have. Inside each of these keys, there are multiple values, although I am only interested in one or 2 of them.
My problem is, that I do not know how to get a list of the subkeys (the 0000-NNNN keys/folders) from the original key I posted. I have looked through a few registry tutorials, and I can view the default value in the listed key, but I could not find how to list the subkeys of the listed key.
Does anyone have any sample code they could share that shows how I can get a listing of subkeys, and then run through those subkeys checking for a specific value in one of the strings contained in the subkey?
I am using VB.net 2008 and Windows XP.

VS 2005 - Delete Certain File Type From Multiple Directories Based On Days Old
May 18, 2009I am new to VB but I do have VS2005 and I was looking at some code examples here on deleting files by days old and I need to do something similar, I would like to start a say C:myData**.xit and search through all sub folders under myData and move all the .xit files based on days old into a temp folder. Then I could verify them before I delete them manually to be safe. So how do I loop through all sub folders? and can I just modify this code to do that?

[2008] Multiple Lines Of Txt File -> Single String?
Feb 26, 2009I have a *.txt file which contains instructions and data, with its own comments (preceded by ! ), blank lines, and each instruction begining on a new line, but occassionally using two lines. Each instruction consists of several feilds seperated by a TAB. Finally each instruction ends in a comma. Only a few different instructions are there (10 different ones) but there are many of each. Spanning a good 2500 lines. Comments and blank lines are obviously of no interest to me. I merely need to read the instructions and the data that follows it.
Now, I have successfully used 'System.IO.StreamReader.ReadLine' to go through it line by line, picking out lines begining with certain strings (first 3 characters of a known instruction). All good, I can 'lift' out the lines of interest and store them, for them to be split up later (seperating their fields into instruction, data, etc..) and then into an array.
The problem is, since some of the data fields in these instructions are so long, it spans two lines, before it ends with a comma. Using the above method, I end up with two array entries for a single instruction, since I have stored individual lines rather than a complete instruction. The only similar situation I can tihnk of to explain this, is to pick out sentences in text, and store each one in a string. Of course these end with a period (full stop) but span two or more lines.
I am hesitant to post an example, since its formatting is rather strange, but it is generated that way from 3rd party software, so I cannot change that for my software application.Perhaps there is no 'graceful' way of doing this, meaning I would have to find a way of 'adding' the second line of the instruction, to the string of the first line. Or perhaps reading each line character by character, literally storing every number/letter until I reach a comma.

Mar 28, 2011I'm trying to copy multiple files from a directory, put them into an array, then copy just the 30 newest files(I haven't coded the 30 newest loop yet). I added a list box to the following code just to ensure the all the files are storing into the array properly... they are. When it try's to copy, it renames the first file to .log, then tells me that the .log file already exist. How do I get it to copy and keep the source file name in the destination folder Eventually I'll loop this and grab only 30 of the files.

Adding A Delimiter - Combine Multiple Files Into One Single File
Jan 24, 2012I've made a rudimentary program that combines multiple files into one single file. Currently if I combine two .csv files together the output comes out correctly for what I need, which is a coma delimited file. When I try to combine two .csv files into a .xls file it doesn't format correctly (I get all the data separated by commas, but thrown into one column in the .xls file). For this reason I believe I need to add a delimiter.I'll post my code below.

May 20, 2009So I'm in the final stages of finishing a program I've been working on for nearly a year now, and this is basically my final hurdle. The Save dialogue is working beautifully, with 'flags' in order to switch it over from the regular input into text boxes to the Listbox input protocol.
However, I'm having a *** of a time getting it to take lines from the text file and put them in the proper text box. Here is an example file:

So with the sample file I provided above, in the textbox named callNameText would appear "SHOWNAME", and so on and so forth. With this build, I get a NullReferenceException on the "Me.Controls(strboxNames(i)).Text() = strAllText(ati)" line.
