Jul 1, 2011I'm using the FileSaveAs dialog control to allow the user to select a filename to save a file either as a doc file, an rtf file or a pdf file (that part was easy).However, after a bit of testing, it seems that the file extension doesn't automatically change when selecting the different file types.If the filename in the dialog is Foo.doc and I select FileType *.pdf and click "Save", my app still tries to save the file as a doc type.Virtually every other MS app automatically changes the extension to match a selected file type from the Office Suite to Paint. here's my code:
Dim dlg As New SaveFileDialog

Jun 3, 2010I'm trying to delete all the files in the same folder that have the same name but different extensions, such as CurrentWallpaper.bmp, CurrentWallpaper.jpg, CurrentWallpaper.png, without putting them in a separate folder. How could I go about doing this? I tried doing
Dim bg As String = dir + "" + Login.UsernameTextBox.Text
Kill(bg + "CurrentWallpaper.*")
but it didn't work. PS: I would also like to use the same technique for loading the image as a background image instead of having to do this:
Try
If My.Computer.FileSystem.FileExists(Login.UsernameTextBox.Text + "/CurrentWallpaper.jpg") Then
Me.BackgroundImage = Image.FromFile(Login.UsernameTextBox.Text + "/CurrentWallpaper.jpg")
End If

View 2 RepliesAssociating File Extensions With A Program?
Oct 12, 2009I get how to do it, and i have been to [URL] before. My question is about what doing that does, is it possible to reverse it? What if you do not know where your program will be, and you are just testing it for now? Is there any way for it to "find" your program, or an easy way to edit where it is opened? For that matter, is it possible to tell if the file has been associated already, is it an issue to try and reassociate? Finally, how can you set the .ico file it uses?

View 7 RepliesRegistry Edits And Icons / File Extensions
Aug 12, 2010Inside the program I have a text box in which a user puts in the filepath to a textfile that the program then uses as a series of commands to perform tasks. This works perfectly, however what I would like to to do to make my program faster is associate the file extension .gam with the program, so when a user clicks a .gam file it opens the program and automatically sets said file's location into the text field, as opposed to using the browse button I added and browsing to said file everytime they run the program.
Through this a user could then make a shortcut to said .gam file and run it right from their desktop, as opposed to rummaging around in folders and whatnot. At the moment my method has been thus, I have 2 folders of importance I have archived with the .exe, Gambits Pro.exe, these are: Gambits, and Control, inside of the Gambits folder is the default storage location for .gam files, as when you click the browse button its default directory is that folder. I have also added a few example files in said folder for a user when they download the program.

Display The Contents Of The Bookmarks Folder Only Without The File Name Extensions?
Jun 3, 2010Instead of creating a listbox to hold the names of one's favorites, I've made it so when you add a bookmark it adds it under the directory (yourusername)/bookmarks. (yourusername) is represented by login.usernametextbox.text. Now I've added a filelistbox to the form and want it to display the contents of the bookmarks folder only without the file name extensions. Just the title. Then when a user clicks on the title it navigates to that specified file by opening a new instance of a browser form. Here's what I have so far:
Private Sub Bookmarks_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
bmarks.Path = Login.UsernameTextBox.Text + "ookmarks"

Dec 15, 2011I'm currently making a program in Visual Basic 2010 for my Course work, and I'm struggling a little as it involves a "log-in system."
The system will save the Users Information in a folder (Called UserInfo.txt) (Address, Password, Email etc..), and the folder name being the username of the User.
When an Admin wants to view or edit a User, I want the Admin to be able to select the User from a drop-down list and when selected, the information of the user loads in and is displayed in the text boxes bellow (on the same form). The Information can then be edited and Saved back to the file of that user selected with a "Save" button.
VS 2010 Multiple File Upload To PHP Script?
Jul 17, 2010I have a client app written in vb.net 2010 which communicates with my auth server via php scripts. I had found and used code previously that uploaded a single file to my server. I'm now trying to convert the headers and code to make it upload multiple files in a single query. The first code block will be the original code by the original author (from a different site), and the second code block will be my current nonfunctional code.
I'm about 99.9% sure the problem is with the header which is being submitted to the server.
Dim filepath As String = IO.Path.Combine(Application.StartupPath, "filename.ext")
Dim url As String = "http://www.FAKESITE.com/php/Upload/index.php"
Dim boundary As String = IO.Path.GetRandomFileName

VS 2010: Prevent Multiple Users From Accessing File At The Same Time
Jul 15, 2011I have written a program in VB 2010 that dumps documentation info into an Excel file. Basically, the Excel file is a log file that keeps track of revisions for design drawings at an engineering firm.
There are approximately 20 people that have access to this program. However, I've run into issues where multiple users may be using the program and trying to send info to the Excel file at the same time. The Excel file is set to read only. My program opens the file with write access, and dumps the info into the appropriate cells, then closes the file. If one person is in the process of using the program, it causes an error with another persons system if they try to use it at the same time.
In some cases, it causes my program to crash, and it leaves the Excel file open on someones system.
Typically, my program would only have the Excel file open for a couple seconds. So, the issues mentioned above are rare, but they do happen.
I'm looking for ideas to prevent this issue from occuring.
