I encountered a serious problem while working withclipboard class in VB.NET.I want to simulate cut-copy-paste operation withmy application and Windows Explorer.User can copy files from Explorer and paste it intomy application & vice-a-versa.My question is-How can I determine if user has copied or cut the filesfrom Windows Explorer? I want to differentiate cut & copy.I am using >> My.Computer.Clipboard<<.

is fine for grabbing a graphic from the clipboard, but I'm after grabbing a file that's been copied there, either copied from explorer or from an email attachment from Outlook.
System.Windows.Forms.Clipboard.GetFileDropList(0) is fine if it's been copied from Explorer, but fails if it's a mail attachment.
Our program will start with the help of a FileSystemWatcher object. How can we check or the file is total copied, for example the file is 100 Mbyte it take a time it's ready for use. Idea:
Do While True
Try
N = testForUse(BigFile)
If N = 1 Then Exit Do

I am using below code to copy a file from one location to other location...
System.IO.File.Copy(Source, Dest)
Code is below. I am designing this code to transfer a file at a specified time. Right now, I have it sending me an email when it succeeds for test purposes. It will be only when the file copy fails later.
Here's my question: how can I get the program to wait until the file copy is complete to report success or failure? Right now I'm using exists to see if it works, but some other method of checking the file will be built in later. Eventually, this will be deployed to various locations for a bit of automated backup.

2 - Saves the server XML file it into a folder separate from the root folder of the application.3 - Deletes the local XML file in the root folder of the application.4 - Copies the server XML file to the local folder of the application.5 - Opens the application.6 - Closes the updater.Now when the application opens, it reads this XML file in the local folder. When I run it stand alone, it works fine and can find this XML file. However, my problem is when the application is opened by the updater, it can't read the XML file in the local folder. I check for this file doing File.Exists(XMLfilename) and it returns false but like I said, if I close the application and reopen it it works fine.
I'm thinking that for some reason the updater is "locking" this file so my other process can't read it? I can't close the process before I open the original application so I'm not sure what's happening here. My Update Folder is the users ApplicationData folder and the root directory of the application is in the Program Files folder.
This is my code in the updater:
Dim ImageDir As DirectoryInfo
Dim fi As FileInfo

I am unable to read a pasted datagridviewrow object from the clipboard. All I want to do is, when a user has the entire row selected and copied, I would paste that row into the clipboard as a DataObject. That works just fine but when I attempt to read that DataObject (after the user clicks Paste) the DataGridViewRow that's saved in the clipboard always has a value of Nothing. Here's the code I'm using for Copy and Paste.

I have an explorer type window in this application I am building and I need to be able to copy files, folders, etc (in any combination) to the clipboard so that they can be pasted elsewhere.

View 1 RepliesI have a DataGridView which lists the paths of a group of files, pptx, xlxs, etc. From a context menu they can copy the name of the file onto the clipboard, or delete the file or rename the file, but I would like to be able to actually attach the file itself to the clipboard so it could be pasted as an attachment to an email or something like that. How do I get the file itself onto the clipboard when I only have the path to it?

I have made a program in Visual Basic 2010 Express. I then copied the .exe file from "My documents...indebug". (Using Win 7) But when I try to run the program on another computer. (Win XP) It says something like "Missing Framework 4.0.30319". The problem is: I can't install Framework updates on that pc. As it's controlled by the admin, and talkin' to the admin is NOT an option.
So basicly, my question is: Is there anyway I can install Framework updates without admin rights. Or maybe make the program run with the current type of FW (2.0 (I think)).
I have an Excel Addin with a button that I would like to use to copy a link to the workbook that is currently active. I am able to get the text to copy to the clipboard, however when I paste it in Word or an Email, it pastes as plain text, but I want a link. I've played with different DataFormats, but I don't think I quite grasp how to use that. Below is what I currently have:

Im trying to get an image from clipboard and save it to a file (.bmp)
Here is my
Private Declare Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long)
Private Const VK_SNAPSHOT = &H2C
[Code].....
Btw (For the first code)If I press the Button the first time and i paste it manually(ctrl+v) to the paint the printscreen image is appeared.Also If i debug the code it works perfectly and it produces the .bmp file.
So im thinking its a timing issue , so I put a sleep(3000) after the keybd_event(VK_SNAPSHOT, 0, 0, 0) command and it still doesnt work.
I have a picture box and if I use Clipboard.SetImage(PictureBox.image) Then I can only paste the image into things like Paint and MS word. I can't paste it as a file into a folder/desktop.So how can I copy the image to to the clipboard and if gets pasted to a folder then it becomes a file?

I've got a program which sets focus to a web browser, selects all and copies to clipboard. all of this works.my problem is pasting from the clipboard. I want the text pasted into a new file which I can create and open programatically but when I place clipboard.gettext in the parenthesis as the string to send to the file, nothing happens. there's no error and nothing gets pasted to the target file.i've confirmed the copy on the windows clipboard viewer just can't get it to write it to the file. (also tried just setting a textbox's text property to clipboard.gettext for testing purposes but it still does nothing)

I am returning to VB building, first time since HighSchool. I am creating a program that has many fields of data that you type into. When you click Generate Button it then writes all that data a .txt file and opens it in notepad.
From that point you copy everything in notepad and paste it into a ConnectWise HelpDesk Ticket.
My goal is to automatically get the data when clicking Generate to populate into the Clipboard, or let it write to the .txt file and then copy all the data from the .txt file into the clipboard. So all you have to do is Ctrl + V after Clicking "Generate"
Is it possible to write a binary file directly to the clipboard in .NET? (Rather than write it to a file and then copy it?) the file is not an executable but will be pasted to the desktopfolder for example. [Code]

I want to scan a directory and see what files are NOT bmp image files. As the file extension can lie I need to interrogate the file itself. I found some code here [url]...?ID=112 that does exactly this however it was written for VB5 and is 13 years out of date! I tried compiling it however VB 2010 baulked and I don't have the expertise to make it work.
View 1 RepliesWhen scanning a data file of this kind of form:
21/02/11 11:00:23, true, false
22/02/11 02:03:43 AM, true, false
22/03/11, false, false
2011-05-21T12:30:20, true, true
The 2nd and 3rd row are not important. How can you, by scanning a file, determine if a row comprises of dates, particularly when they have inconsistent formats? In the example above, for instance:
1) 1st line is date and time
2) 2nd line is date and time but also AM/PM
3) 3rd line is only date
4) 4th line is GMT format.
I'm not requesting code, but perhaps an algorithm or some guidelines on how to achieve this.
How can I programatically determine if a file with a certain extension (XLS, for example) is really an Excel file and not a VBS file, for example, that has the XLS extension?
