View 4 RepliesI have a treeview control which is being used to browse various folder on the users system drive. It can also be set up to connect network folders using UNC paths e.g "serverfiles". At the moment I'm getting a list of Directories by using My.Computer.FileSystem.GetDirectories however this obviously fails when the folder is password protected.
Is there a way that I can get Windows to open the credentials dialog as you would see in Windows Explorer and deal with the credentials side so then the user name & password is cached as well?

View 1 RepliesI'm creating a windows application form in vs 2005 for a client.. It's a data-tracking application. I have a few questions.The client wants a logon screen to be added into the application (at least any way or method that'll ensure that security was applied). My question in regards to this topic would be; Is it necessary to create a logon screen (or even a user authorization) for a windows form? I realize that in a webform project, security should always be considered and should be applied in all areas. Although with a windows form, I thought you can authorize who can gain access to the application by defining which workstations to install the final production release of the application (when its time to deploy the file). Is this correct?
My next question is, what is the best method to exporting data from EXCEL to SQL tables? I have many Excel files that I'd like to take portions of data from each file and insert them to there proper table.
The last question is about deploying a windows form application. As you can tell, I don't have much experience when it comes to developing Windows Form projects. Anyways back to the topic, When deploying a project, does it provide a .EXE file (installation package) to install the application on the workstation? Or is it a .EXE file of the application, where you can run it and no need to install anything?
I'm writing a backup program for personal (for the moment at least) use.
For some directories (network directories / protected directories) credentials are needed to access them.
I can setup different jobs in the program to run at specific times.

I want to also store the usernames and passwords which the jobs will need.
What and where would be the best way to store these?
Changing permissions on the directories is not an option.
I am trying to control the security board using the Windows Firewall which connects to my server that was made in VB.Net. My only problem is when I open the Windows Firewall my server crashes. It also displays this error: "Error, win%fir%90y4e does not support this server. upgrade you version of Winsock.". So I upgraded myself to the latest Winsock that there is out there. After doing so I try again and my server still crashes, but this time with a different error. The error this time was the following: "Error, no client is available for win%fir%90y4e. try again later.". What do I do?

I am trying to build a simple AutoUpdate application using VB.NET. It was quite simple. That is, I put the newest ZIP file in my hosting site, and then download it using WebClient.DownloadFileAsync. After it get downloaded, I extract it using [URL]
But each time I run the unzip.exe using Process.start, Windows 7 always show Open File Security.
Is it possible for VB.NET to bypass such security restriction?
Btw, this is my code of using WebClient.DownloadFileAsync, in case any one google about it and landed on this page :
Public Class AutoUpdate
Dim installationFolder As String = "C:Program Filesxyzabc"
Dim updateFileNameTarget As String

Currently i am using wpf with vb ,vs2008,framework 3.5 ,there i am having code to connect with camera and capturing video.

Here in this code while executing the bold ,italic marked line ,a dialog box appearing to select video source even if one option is there(i.e i have connected one camera to my pc through usb).Its coming in windows 7 not in xp ( Same code ). Is there any setting to stop this dialog box or to select the video source in code without showing the dialog box.
I am using a Windows Dialog form in my VB 2008 project. I bring up the dialog form no problem with the following
Dim resultNewInc As DialogResult
resultNewInc = frmDialog.ShowDialog()
If resultNewInc = DialogResult.OK Then
...some code here ...
End If
And in the Dialog Form, the OK button has code
Me.DialogResult = System.Windows.Forms.DialogResult.OK
Me.Close()
But there is one problem. If I call up the dialog form again, the form controls have the text values that were typed in during the previous instantiation and a class which is part of the form was not disposed. So it looks like the form is being "hidden" and not closed. I tried to use the code form.dispose but it didn't work.
I am using Process.Start(fileName) to let Windows open certain files outside of my application with their 'default application'.If "fileName" for example is a ".txt" file, it opens the file in Notepad. If it is a folder, it opens windows explorer with that folder selected.This all seems to work well, except when the user enters a file that has no application 'linked' to it.(a file that has no file associations)I have wrapped the Process. Start() in a Try/Catch block so that any errors are caught and displayed.When I now open a file without any file associations (windows does not know with which application to open it) it tells me that it cannot find any application to open it with. (The exact error is in dutch so I don't think that's going to be much help here, but I think it's clear what's happening, no?)What I would like to happen in this case is that the windows "Open With" dialog comes up, asking the user to select an application to open the file with. Now it just displays the error message and continues, making it impossible for the user to open the file unless he browses to the file manually and sets up the file association, something many users probably don't know how to do.
