Check If An Excel File Is Opened By Another User?
Apr 26, 2012My program opens 4 excel spreadsheets updating info. I update one at a time and then close it before opening the next one.I want to add code to my program to test if the file is already open, before trying to open it. Occasionally someone will have one of the files opened and it causes a crash. If I test to ensure it is not open, then I can avoid this.
View 7 RepliesDGV CheckBox - Recognise Which Check Boxes Are True And Update Automatically When The Information Is Opened From A Text File?
May 8, 2012I have code which saves DGV contents including check box columns as a comma separated text file. I also have correct code which will take the text file and re-insert it into the DGV at a later time. This all works.When I'm working on the DGV, I have this
Private Sub DataGridView1_CellValueChanged(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellValueChanged
If DataGridView1.Columns(e.ColumnIndex).Name = "Column12" Then[code]....
So that when the check box is true, columns 1 and 3 turn different colours, and when false, go to a yellow colour.However, when I "re-insert" my DGV info from my text file, the check boxes come back correctly - as true and false on the right rows - but columns 1 and 3 don't change colour. I've tried a "DataGridView1.Refresh" option but not getting it to work.The DGV is unbound. I need it to recognise which check boxes are true and update automatically when the information is opened from a text file.

May 1, 2012I've got an application which I want to only have 1 open.How would I make it check if the application is already open and only open if it isn't? I've had the idea of using 2 forms, one of which is the proper application and the other which just checks if its running then opens the other form.I would imagine it would check if there's more than 1 of the process name running and if there is close all others?
View 5 Replies.net - Check If Shell Program Has Opened?
Jan 5, 2010I'm launching an Access ADE, using Tony Toews auto FE program. The AutoFE programs will, if newer version available, copy the latest version of the ADE from the server, then launch it. My code looks like:
Dim stAutoFE As String = "V:Appsautofestartmdb.exe /cmd /inifile: " & """" & "V:AppsAutoFESSP.ini" & """"
Shell(stAutoFE, AppWinStyle.Hide, True)
System.Threading.Thread.Sleep(1000) ' Time delay
[code]....
I had to put the Sleep delay in, otherwise the GetObject would open the ADE a second time.But I don't know how long the copy from the server will take, so I need to remove that Sleep line and check that the ADE has opened.

Open File Retain The Directory Of The Last Opened File?
Jan 10, 2010So I open files and do whatever with them right. I've set the initial directory to equal the last directory, but whenever I open multiple files, it never sets the directories properly. It acts as though nothing was opened there, so it takes the previous directory as the last one. Thoughts on what's not working? Here's the code.
Code:
With FileOpenDialog1
.InitialDirectory = LastDirectory
If .ShowDialog = DialogResult.OK Then
[code]....
I have multiselect enabled earlier and everything else works but this. When you open a single file, the last directory works fine. It only happens with multiselect.On another note, does anyone know why it freezes when I try to do a lot of files and use another program? I opened 700+ files to see what would happen. When I switched to a IM convo, it froze. When I left it to run, it worked.

View 2 RepliesHow To Tell If Certain Excel File Is Opened
May 26, 2010I'm exporting my Dataset to an excel file, and I want to make sure I keep any file errors under control. One in particular that I'm concerned about is accessing a file that's already open. A general IOException occurs that says:
"The process cannot access the file 'C:Reports eport300.csv' because it is being used by another process."
Here is the line in which the error will occur:
Dim output As New IO.StreamWriter(path, False, UnicodeEncoding.Default)
I guess I could just throw a try catch around it, but what if an IOException happens that isnt related to this particular incident? Is there a way I can check to see if the file is already open before allowing this code to run? Especially when I'm using excel.

.net - Overwrite A File That Is Currently Opened By Another User
May 4, 2011I have a couple of files which I have to update periodically through a process written in VB.net . These files are on a server and part of a domain that many users can access. These files should never be written to as they are for reference only. I need to be able to overwrite some of them even if a user has them opened. Is it possible to do this? Presently the files permissions are not set as read-only but I can do this as long as the user under which the process runs will still have permission to overwrite them.
UPDATE: thx for your responses. The files are pdf and are opened by clicking on them from windows file explorer. This also happens when a user simply has the file selected in windows explorer.

View 5 RepliesClosing Form After Large XML File Is Opened?
Oct 21, 2011I'm working through an example in a programming book and stumbling across a problem that I can't seem to figure out. The program in question is basically a very basic 'level viewer' for a tile based bitmap game (its a game creation book). The source code from the author was written for Visual Studio 2005, and I am using 2010. The source code imports fine and the program runs correctly.
I built the same program on my own, starting from scratch in VS2010. The program works like this: It opens a tile set palette (bitmap form), then uses an XML file to create a 'level'. The XML file indicates which tile goes where on the 'level'. The XML file is roughly 1.9MB and has roughly16,000 entries (the program creates a level that is 4096 x 4096 pixels using 32 x 32 pixel tiles).
Running and closing the program from source code runs exactly as expected. Running the program from my version runs exactly as expected. Closing it does not. It basically hangs up for about 2 minutes on close. (for reference every loads in about 3 seconds). I've determined that it is the XML file that is causing the problem by excluding the portion where it loads the XML. In that case it closes fine. If I cut it down to just a few records, my program closes fine as well. So it seems like the program is having trouble dumping the XML document at close.
I've tried to track down any differences between the source code and my code, and the only thing that I have found is that the References in mine are all using .NET version 4.0 and the references in the source are using mostly 2.0 and some 3.5 (System.Data.DataSetExtensions, System.XML.Ling.dll, and System.Core.dll)
The code for the entire form is:
Imports System.Xml
Public Class Form1
Public Structure tilemapStruct
