I have a PictureBox control (in Form3) that is used is used as a drop box where the user can drag and drop one or more image files at a time. When the user imports files, the form (Form3) will close itself.Meanwhile,the application stores file data in Form1.ListView1.The following is the code that I use for PictureBox's DragDrop event.
'Form3.PictureBox1_DragDrop
Dim s As Array = e.Data.GetData(DataFormats.FileDrop)
For i = 0 To s.Length - 1[code]....

I insert a text box into form1. I move the mouse pointer on top of the text box. I press down on the left mouse button and begin to drag the text box. The problem is when I let go of the mouse button the text box is not dropped. it remain floating around. My only way out of this is to press the escape key which places the text bnox bak to its original location. Thinking that it might be my mouse I tested it in Power point and everything works correctly.

So essentially, I have this text editor. How can I make it so when I drop a text file over it, it opens it in textbox2? Or when I doubleclick on the file, it automatically opens it in my program (in textbox2).

I am writing a Windows service to import data from CSV files dropped into a directory. One of the steps is to load an XML file with validation rules which I load into a List(Of T). It will pull the data, and then I have it pass the list to a class that monitors the folder and processes the files. After that I clear the list and read in the next file configuration. Now I have noticed that the validation rules aren't matching up and it seems that the list is being passed as a reference type even though the signature is of a value type.Is there anything I can do to get around this?
[Code]...
So here when I pass it, at first it will have 3 validation rules in the new ImportService class I created, but when I call fields.Clear(), it wipes out the class member of the ImportService class.

I have a filesystemwatcher waiting for .jpg files to arrive from the camera.he file system watcher invokes a delegate (it works but is that the proper way to handle it?) sub that does a couple of things:1. Adds the just arrived file name to a table2. Attempts to display the image in a picturebox on the form. When it displays the image it imprints some information on the image that the user has entered on the screen. I use a file stream to retrieve the image.The problem is, I'm getting a file in use orror on the "Img = ystem.Drawing.Image.FromStream(fs)"statement. Not all the time. Sometimes I can add three or four files to the folder in rapid succession with no issue. But then out of the blue the error will occur. Sometimes it's there to stay but other times it will go away and allow me to add morefiles.

I have some code that does a Find & Replace in some text files, and closes the file when complete.However, when I try to use the Kill command in VB to cleanup these files (they are temporary files) when the program is closed, I get errors that the file is in use by another app or process.Is there a way I can force these files to close first? This also happens when I scan a document using the EZTWAIN.dll Scan to native function.Everything goes fine, but if I try to scan again to overwrite the file, the file is in use.This is happening on Windows Vista SP1.

In a Windows Form application (VB.NET) I have a combo box and under certain conditions, when the user opens the DropDown list, I want to display a warning message.All of this works well: In the DropDown event, I check the conditions and if required I display the warning message.The problem is that when the user clicks on Yes on the warning message, I move to another tab on the main form and the drop down list still shows even though I've moved away from the tab containing the combo box.I've searched quite a bit and tried to set DroppedDown to False, call OnDropDownClosed, etc but nothing worked.It seems that when I try to close the drop down list from within the DropDown event, it doesn't work.

1. Although I have enabled AllowDrop property of ComboBox it does not allow me to drag and drop files into ComboBox. Why?
2. Then should I process incoming files in the _DragDrop event, yes?
3. How can I get the Files.Count to get the number of dropped files?

I use a .NET richtextbox and I want to have the EnableAutoDragDrop property set to True. This allows user to drag&drop text, rtf and images around etc. However, I need to process files dropped into the richtextbox myself - I do not want them to be embedded as OLE objects when they are dropped.
How can I overcome this? Is there any way to delete embedded files from richtextbox?
(I've found API DragAcceptFiles which doesn't work for some reason.)

Do anyone has any idea of how can I drop files to another app? I have found that it can be done with SendMessage WM_DROPFILEs, but I don't know how to structure the wParam.
I also found this on MSDN [URL]..But I still don't have any idea of how to do it,I also found this code, but is for Delphi:procedure DoDropFiles(Wnd: HWND; Files: TStringList);

I have a doubt. I'd like to make a program where you can drag music files (mp3, flac, wav, wma..) and video files (avi, mpeg, mp4, vob, mov) and get the property values of this ones... For example, bitrate, KBps, size, etc, to put them in textbox or listboxes.

1) I'm dragging a file (.txt) into a rtb which works fine, but how do I get the filename? (messagebox whatever)
2) How do I restrict files to drop? (like a .exe)
vb.net
If e.Data.GetDataPresent(DataFormats.FileDrop) Then
Dim Files() As String
Files = e.Data.GetData(DataFormats.FileDrop)
Dim sReader As New StreamReader(Files(0))

I am working on a vb forms application in VS2008.What I am looking to do is have 3 file managers on the form.The top is the source where files can be copied to the 2 other file managers.What I have been looking for is an example of the file explorer so I can modify it.So far I have been unsuccessful in finding a good example so I am here to ask the experts.So the gist is the first file explorer will allow a user to connect to thier local hard drive.The other two file explorers would allow the user to connect to two different servers through entering the path they want to view those file trees.After that the user could click on the file they want to copy and then hit a button for example and the file would be copied from the local to the two other areas.Would it be easier to just use text boxes with a confirmation that the files are being copied?Or can a full file manager be built to drag and drop files?

I am trying to add multiple files to FTP server by dragging and dropping and I am able to do that using try catch block and if we give the ftp settings correctly it takes 1 sec to upload them but when we give wrong details it hangs up and dosen't give me any error message though If I give an exceptional message.
Now I am getting error message as well as success message for every file I add.I do not want that to be happen.where should I give messages for success and failure so that it should take few seconds for uploading and if not should give me a message immediately.
Here is my code:
Private Sub uploadFile(ByVal FTPAddress As String, ByVal filePath As String, ByVal username As String, ByVal password As String) 'Create FTP request

I should mention that I'm mainly concerned with Random files.Which is the best method?
1.) Open file, manipulate data and immediatly close the file. (Which means doing this alot everytime data needs to be read, edited, deleted, or saved)
(2.) Open the file when the app starts and let it open for data manipulation until it's time to close the app at which time the file would be closed.
I was always taught option 1. The main reason at the time was to cut down on the chance for data corruption in the file or an outright loss of the file due to outside circumstances like power failure.

I'm currently in the process of building a text editor type program, and have run into a brick wall. I haven't done VB in years, so I may just need a little reminder on some things. I have coded everything so far as far as opening files, saving them, changing fonts, colors, etc. However, I'm looking to add a Close button to my menu strip that will just close the currently opened file, and not the entire program, while also ask the user if he/she would like to save before closing the file, and then if they select yes, it will show the save dialog, and if not, it will go ahead and close the currently opened item.

Here is the problem: I have written an application that opens an excel file, copys a chart to the clipboard, then closes the excel file. It works fine except under a very special condition. If the user has an excel file open and then runs my application, the open excel file closes. To make this more confusing, if the user then reopens an excel file and runs my application again, everything works fine. It will continue to work fine untill the user reboots his or her computer. Then it will occur again one time
Here is the section of code I found the problem is in:
Private Sub Get_R1C1_Image() 'Gets excel data to display
Dim objXLS As Object = CreateObject("Excel.Application")

This question only applies to files of line-terminated/text strings.[code]I suspect that ultimately, I will generate the myfiles version of the HD file as I write it to disk,but at this point in my VB.net 'skills', until I can prove what I've written by reading it back and having control of it in my program, I can't assume anything about the data/format/file that I have written.

When the Point of Sale program we use makes a change to a row in the SQL database, it automatically updates the ModificationDateTime for that row, and the precision is in milliseconds. I have another column called "LastSyncDateTime, and when theModificationDateTime is greater than the LastSyncDateTime, it downloads the row, finds the column that got changed, does its thing in my program, then updates the LastSyncDateTime with the same value as the ModificationDateTime so it doesn't repeat itself on the same row.The problem is that when it goes back to update the LastSyncDateTime, it loses the milliseconds precision, so the SQL Stored procedure to download new changes doesn't work ("Give me all the rows where ModificationDateTime <> LastSyncDateTime").
