I have published an application. On some computers it is working very well but on others when we run setup files, windows throws error "Windows does not know what program to use to open this file"
This error comes for application.manifest. Also I checked the icon for this manifest was like the icons that are given when no associated program is installed for a certain file.
I got this chunk of code off the internet, i think the sample program was called "store images and files on sql server" i added the delete routine, so it is a little better than when i found it, but it opens pictures in big picturebox at the very last line, i was wondering if there's a way to call windows photo editor or something newer instead of the form it's calling

View 4 RepliesI 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
Private Sub btnStartUpdte_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStartUpdte.Click

View 9 RepliesI am trying to write a code to save and open data that is in my application. My application contains hundreds of text boxes, combo boxes and labels. I have created an array for each set of data, i.e.,
glist(0).store=combobox1.value
glist(0).cat=combobox2.value
glist(0).it=label3.text
glist(0).quan=label4.text
glist(0).total=label5.text
up to glist(89).
Is there a way to write a code to loop through the array and save the values so that they can be opened at a later time in my application? The array will contain Doubles and Strings.

View 9 RepliesI 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.

I am trying to write a section of Access VB code that opens the Windows dialog box and allows my user to select and open a file to verify it is the correct one. (Then I use the file path and name to copy, rename and move the file). I have been trying to use the OpenFileName structure and have succeeded in capturing the file path and name my user selected... My main problem in all of this is getting the file to actually open so the user can verify it before I commit the actions noted. This probably can be done as a part of the OpenFileName dialog if I understood it better, but but isn't there also a trivial way to open a file if you have the path and name?

I'm not sure why it is having a problem finding it.I created a try catch format because it seemed to have a problem at one point between looking in the 32 bit program folder or the 64 bit even though the program itself is in 64 bit...[code].....
View 4 RepliesI have a program that runs some data manipulation on a file when it is double-clicked and then displays this to the user.However, when I double click on the same file type of a different file it opens in a separate instance of my program instead of the same instance already running, i.e. some message that says would you like to reload file, YesNo, and then given the answer perform the action required.I have found some code to stop a second instance from opening, but this is inconvienient for the user to close out of the program everytime they want to view a new file.[code]

BTW if you're curious it's not a harmful program I'm making.
So all I've done so far is put the file in the resources folder of the program, but I don't know how to actually launch it.
