I want a code that checks if there are any files in a Folder. So I want to specify the folder name.
This is what it should do:
It Checks if there are any files in the folder (Data)
If there are no files in folder:
Form2.Show()
If there are files in the folder:
MsgBox ("Welcome", MsgBoxStyle.OkOnly, "Welcome")

I was wondering how i would go about make my program loop threw files in a folder and if that file is .jpg it will delete I use this to see if the file exists and delete it
If System.IO.File.Exists("file.jpg") = True Then
System.IO.File.Delete("file.jpg.jpg")
End If
but how would i do a loop and grab every .jpb file so they can be deleted

Im trying to write a loop that will read through a number of *.csv files in a folder and then stuff the data into SQL. The code works and will happily put the data i want for a named file into SQL no problems. So when i had that working i then tried to loop it so that it would do the same for all files in the folder until all files had been done, and not error out if there where no files etc.
Maybe im tired (well, i am) or not had enough coffee but i just cant get this to work, it should be simple - i know it is infact, but its making ME feel simple.i think i should have an integer count in there, but similar examples ive seen dont use one. Also when trying to open the path i get an error at runtime "the path is not of a legal form"
code:
Public Sub ImportCUSTCSVs()
Dim dt As New DataTable()
Dim line As String = Nothing[code].

I've set up a basic loop to delete all the files in a particular folder. I've set the loop in a Try block so it doesn't crash the application when it gets to a file it can't delete. I'd like for the app to just pass over these type of files. At the moment, my loop stops completely when it gets to that exception.
View 1 RepliesToday I investigated a logical bug in our software and figured out that this is related to the way VB.NET thread variables inside a loop.Let's say I have the following code:
Dim numbers As New List(Of Integer) From {1, 2, 3, 4, 5}
For Each number As Integer In numbers
Dim isEven As Boolean
[code]....
The problem is that isEven is declared but not assigned.In this specific case, it would be correct to write dim isEven as Boolean = false but I haven't done this.In VB.NET, a variable that is declared inside a for loop keeps its value for the next itaration. This is by design: [URL]but this is also dangerous pitfall for programmers.
However, until now, I haven't been aware of this problem/behaviour. Until now.Most of our code base is C# anyway, which doesn't allow the use of an uninitialized variable, so there is no problem. But we have some legacy code that is written in VB.NET that we have to support. So the best thing would be to generate a warning or even an error in this specific case.But even with Option Explicit / Option Strict this does not generate a warning / an error.Is there a way make this a compile time error or maybe a way to check this with FxCop?
I saw some applications where the Bin folder (debug and Release) contains images and databases. How is this done? Are files manually put there? meaning do I have to copy and paste it or there is better way?
View 5 RepliesI have created a project where I can attach files and I am displaying the name of the file, example:
Mytestfile.doc
mytestfile.txt
Mytestfile.pdf
I have the names being displayed on a listbox, so far everything is working just the way I expected to work.When a file is selected from my opendialogbox, the file gets saved into a folder under my local disk, so far so good.The problem that I am having is deleting the file from the folder.I have added a delete button and I would like to when I click or highlight one of the file names to go into where the file was saved previously and deleted This is the code that I have for the delete funtion:
[CODE Dim sFileName As String = "C:program filesSupport DeskAttachments" & ListBox1.Text
System.IO.File.Delete(sFileName)][/code]
The problem is that if I add the code to the clcik event under the listbox, it works great, but if I add the code to the click event under my delete button, it doesn't work, what I found is that under the path, if I am under the click event from the listbox when it gets to the lisxtbox.text it displays the file name, which is what I whant, but when i tried the code under the click event under my delete button the listbox.text is blank.
I am looking to access all the files from a selected folder . The folder is selected through a folderbrowserdialog. My problem is using a filesystemobject in Visual Basic of Visual Studio 2005 to store the filename and path in a folder object. I have done the same using VB6 and it worked.
The following is my code in VB6.
If filesysObj.FolderExists(folderSel.Text) Then
Set folderObj = filesysObj.GetFolder(folderSel.Text)
For Each fileObj In folderObj.Files
file_name = fileObj.Name
firstpos = InStr(file_name, "fcs_")
[Code] .....
Now, I am trying to make changes to my Vb6 code so that it works with VB2005. Following is what I have done so far:
Dim folderObj As String
If My.Computer.FileSystem.DirectoryExists(folderSel.Text) Then
folderObj = System.Environment.GetFolderPath(folderSel.Text)
I am getting an error (InvalidCastException) on line, folderObj = System.Environment.GetFolderPath(folderSel.Text). The message I get is: Conversion from string "C: empfolder" (which is the path) to type 'Integer' is not valid.
in the current project im making i've decided to add in some tools, 1 of which is a renamer based of a renamer app that already exists (called scdtoolz), i want to build my own version of it so i can learn some new things, and build a nice GUI version of it.[code]So what i have managed to determine is that the current app scans the folders contents for the CRC32 Checksum, and renames based of that, since the 456.bin's CRC32 Checksum was 2274F80B, and in the text file 2274F80B is found here 'WWF - Rage in the Cage (T-81015)(U)#2274F80B#'So now i have determined game identification is based of the CRC32 checksums, how would i go about coding a similar ap in vb.net?first i need to make the app scan a folder, but how to return crcchecksum? and then rename if check = XXXX? If MD4 sums are easier/simpler i can use those instead, im lookin at a few hash app sources now, so i think i can see how to get the md5 but not the crc32 yet, or how to rename the 2 files and folder based of the text file.
View 6 RepliesI am working with VB 2008. I want to be able to run this program say in N: and it will show me in an excel sheet the following:
Folder Path Size(GB) Count of Files
N:Clients 0.53 308
where clients contains subfolders and files and the size is the total of all those files within each folder and the count is the total within each folder also.
This works fine as it is but i have to select one by one the top level folders and some of them are huge so it takes forever to give me an answer.
1) I would like to see in my spreadsheet the following by only select the network drive n:
Folder Path Size(GB) Count of Files
N:Clients 0.53 308
N:Software 10.7 15430
N:Billing 0.98 105
2) I would also like to know if this is the faster method.
3) I tried adding a progress bar so that the user can have an idea of how much this will take but i had to remove because it was not working.
4) I would like to see the folder name, size of folder and count of files in the listview.

I wrote an application that copies files from Folder(A) into Folder (B) First it checks if the files exists if yes it will copy them and it will over write the them in fodler (B) and is working great , but if I have a file in Folder(B)that is located in a subfolder the file inFolder (A) will not be copied to the new location.

I have a folder save here: C:MyFiles/And in that folder I have a few .txt files.I am looking to see what would be the best way to open each .txt file in that folder and search for the value Error or Warning and then when it does it must tell me what files do contain those words.What would be my best option? To create a Stored Procedure with t-sql to do this? or To create a .exe with C# or VB.net code.
