I'm getting an access denied error when I run this code:
[code]...
If I change SearchOption.AllDirectories to SearchOption.TopDirectoryOnly then the code executes without any errors and the files in the top Directory are displayed. Apparently there is an access method that I need to set but I'm not sure how to implement it into the existing code.
I am having a problem with my application which I recently created. The application was designed to search for files either recursively or non recursively for files with certain attributes ie. file size, date created, etc. The application works (well sort of)....
I currently have the application creating a tmp file using IO.filestream and IO.FileMode.Create and then I'm using StreamWriter to write the names of all the files that are found with the matching attributes to the tmp file that was created in the tmp directory. What I have found is this:
If the parameter to do a search recursive is True then the names of the files through the directory tree are successfully written to the tmp file and all is well however if the base path specified does not contain any sub directories and searchoption.alldirectories is used I cannot get any of the files names who match the search criteria to be written to the temp file. If I add a console.writeline(sfile) just above the call to write to the temp file the names are written to the console successfuly (just like they should be to the temp file).
If I choose not to do a recursive search and specify using SearchOption.AllDirectories then I see a similar problem...none of the files in the top level directory that meet the search criteria are written to the tmp file like I'm telling them to. Again if I add a console.writeline just before the call to write to the temp file the names of all the files in the top level directory are written to the console successfully.
I cannot figure this one out...I am stepping through the code with the debugger and based on what I'm seeing I should not be having this problem. I know the logic is correct because I can write it out to the console correctly...
i'm a newbies in vb. i have code to view folder and sub folder.
Dim i As Integer
'Dim di As New IO.DirectoryInfo("c:")
Dim folders() As String
[code].....
im having some issues with getfiles, and i cant seem to pin point the cause, heres the issue:Im scanning a folder which has a mix of file types (.7z, .rar, .bin) and for each file im checking a dat file to see if that file (via the crc32) is listed in the dat. Pretty simple, but my code is randomly hit/missing heres what i have around my vb For Each strFile As String In System.IO.Directory.GetFiles(ComboBox1.Text, "*.*", SearchOption.AllDirectories)Next ComboBox1 .Text is a folder path for example 'C: est'
And inside of that i hae the crc32 code, the crc 32 code works great, the issue is with the above so no need to post lots of crc32 code. Now the problem im having is say i scan a folder with 10 files, lets say 5 7z's and 5 .bin's, sometimes the scan will scan all 10 files sometimes only 5 7z's and 1.bin, sometimes no .bins, sometimes only the .bins.If i put the .bins in a folder on there own and scan it will scan them all, same with the 7z's, so why is it not working when there all in the same folder?EDIT: I think the error is here 'SearchOption.AllDirectories' but i dont understand how to fix it, if i put all files into the root of the folder it will scan all of them, but i wanted to be able to scan the files in the subfolders to hence the SearchOption.All Directories, but it seem to be failing
When I have a directory setup with a subdirectory and both the top directory and sub directory have files in them I get a list of all the files with no directory info. That's OK, but I need to restore them to another location with the same directory structure in place. I'm essentially copying all files in a directory and it's subs to another location. The problem is the sub directory info is not in the files list so everything goes into the main directory. How do I get around this or can I? Here is what I'm using now.
I have a directory, NewProg in Program Files and a sub directory under it called Sub.
files=dir.getfiles("C:Program FilesNewProg",searchoption.alldirectories)
My.Computer.FileSystem.CopyFile("C:Program FilesNewProg" & File.Name, "C:NewProg" & File.Name,True)The Sub directory is not created and even when it is there, it always comes up empty with all it's files copied into the main NewProg.

I have two combobox in a form: Cb1 and Cb2
When I load the form, Cb1 and Cb2 are connected to a bindingsource.
When I change Cb1, the code (below) changes Cb2 to show only the items according to Cb1
This is working fine.
The problem is when I change Cb1 , change Cb2 and click the save button..... Cb2 seems to be 'lost'...
I'm using VS2008.
CODE:

what I need to do is if the user select "C"
the the colreporttime will show the time of this change unless the old value is C
I'm getting familiar now with using the Dataset Designer and how it makes for quick and easy updates and query of tables. I use to use the OleDB commands and leave the Connection String as a Global Constant so I can easily change it if the server name changes, or if we have to re-direct the .NET to another instance of the database.
But now that I use the Dataset designer I'm concerned that I maintain flexibility and support in the long run. how the Dataset designer works and where it stores it's connection string info? And how difficult that would be to update. It looks like I modify the App.config file, but I'm unfamiliar with this.
What am I getting myself into? It looks like a standard XML file. Is that it?
Ok, so I know I have to change the labeledit to true but that doesn't change the selected node to be able to edit, so how does that work?
Along with renaming I have it set to that a user can add a node. So once the node has ben added how do I let them rename it as it is being added and without being a prompt or inputbox? So lets say I cam clicked on a parent and they click add node, it adds it to parent but I have it so it is default "New" but I want them to edit it as it is added. I think it will be along the same lines as clicking on one and rename but I have to start some place.
Can someone please help me create a very very simplistic sample page as the chat page included is too coomplete. something as simple as detecting a change in the database and displaying the word "change" on screen in realtime for any client connected.and I tried creating a global.asax file into which I added in the line mentioned in the link above, but it does not seem to like the word "Setup" in the line [code]

I have 10 Comboboxes in a form. All these combo boxes have databound items which come from the same column in a table in the database (access 07) (Am designing a billing software, and these comboboxes show the items (10 lines of them).All these combos reside in one Groupbox.Now for the strange (scary/funny) part, whenever I change a value of 1 combo, all the other combos change automatically and show the same value as the one that was changed. (strange!).
View 6 RepliesI have a change calculator program that has two user inputs and 6 outputs. The user inputs how much money is owed, then how much money is received. IT will then display how much change you need to give back. It should also display the different types of currency that are available to give as change. Here is my code so far.

I'm working on a simple base form in which all the other forms in the project will inherit. This base form only adds 5 properties (at the moment) dealing with painting a gradient background. The problem I'm facing right now is when I change a property on Form1 (the test form) and click run it doesn't show that change. I also checked the .designer.vb file and when I make a change it's not added to the code behind file, I'm at a loss right now to why.

I am throwing some data out into Excel and am having some formatting troubles. I have 5 columns (date, time, a long number I don't want displayed in scientific notation - text is fine, text, text). I can get it all working with numberformat, however I have to do them different ways.
Date works this way cell.numberformat = "m/d/yy" and it formats it to say 3/1/11
Time works this way cell.numberformat = "h:mm AM/PM" and it formats it to say 8:07 AM
For the long number cell.numberformat = "@" and it doesn't change the format and it gets displayed in scientific notation
BUT if I use cell.style.numberformat = "@" it works as it should, but it messes up all of the date and time cells. Apparently when you use style.numberformat, it doesn't just apply to the cell you're working with. If I try using style.numberformat with the date and time formats, they don't change and are entered as if I didn't change the format at all.
So, I've got a text boxes which loads up a content from a XML file, usually a numbers I want a button, so when I will change the numbers on the text box, the data in file will change as well, in other words a save button That's how the data is being taken from a file
