Win App - Choose File And Enter Into Database?
May 19, 2009
I have a windows app where I want to allow users to choose files from their computers/network and save the actual file into the database. I've done this before with web apps and here's the code that i've always used (with an html fileupload control)
Code: Dim postedFile As HttpPostedFile = Me.FileUpload1.PostedFile
' Validate If Not postedFile Is Nothing AndAlso postedFile.ContentLength > 0 Then Dim desc As String If tbDescription.Text = "" Then desc = "" Else desc = tbDescription.Text End If
[code]....
This code put the actual file into my database table. I was wondering if there was anything like that for windows applications.

I have many fields in the page and the last field is a dropdown with list of values. When I select an item in a dropdown and press Enter, it doesn't do the "Ok". Instead I have to manually click on Ok to Submit. How can I do by pressing Enter on my Keyboard rather than Clicking on "Ok" button after selecting the value from dropdown list. I have set the SubmitBehavior to true.

I need my code to be able to choose 5 random files from a folder. I was hoping I could instantiate the Scripting.FileSystemObject then grab the target folder as an object and do something like FolderObject.Files(12).Name but apparently that's not doable. What I did works, but is sloooow:
FS = CreateObject("Scripting.FileSystemObject")
Folder = FS.GetFolder("c: emp")
for y=1 to 5

I am currently working on a family project which is based on "Who Wants To Be A Millionaire?" show. There is a huge diffrence between the show and my project. My project is a christmas edition and the goal is not to get money or something, since I will not add it... Erhmm... Let me get to the point. I have already designed a layout and scripted some things. I have about thirty questions but I do not want them to always spawn in the same array, if you know what I mean. I want the program to randomly choose one of those thirty questions and NEVER choose the same question in the same program run. By the way, there are four options on my project: A, B, C and D. I have got everything, I just need a code.

I am creating a program that will help in upload files to a website. One of the things that the website uses is the "Upload File" button. When you push it an "Open" dialog box opens (like OpenFileDialoge). What I want the program to do is auto fill in the direct file location for the website. So that the dialog box won't open or won't need input.

i created a form with a combobox that lists out Assignments ( assignment 1, assignment 2, etc...)......what i need to do is let the user choose an assignment, then the program should look for the matching text file in a folder, ex: user picks assignment 1, and the program will read from assignment1.txt and display the result in a listbox. I have everything except the coding to match what the user chooses and the text file to streamread.

I'm writing an Excel file recovery program with VB.Net that tries to be a convenient place to gather and access Microsoft's recommended methods. If your interested in my probably kludgy, error filled, and lacking enough cleanup code it's here: http:[url]..... The basic functionality seems to work although I haven't tested graph macro table recovery yet.
It occurred to me that Vista and Windows 7 users could benefit from being offered a list of previous versions of the file within my application if the Shadow Copy Service is on and there are previous copies. How do I do this?I looked at a lot of web pages but found no easy to crib code. One possibility I guess would be to use vssadmin via the shell but that is pretty cumbersome. I just want to display a dialogue box like the Previous Versions property sheet and allow users to pick one of the previous versions. I guess I could just display the previous version property sheet via the shell by programmatically invoking the context menu and the "Restore previous versions choice", however I also want to be able to offer the list for Vista Home Basic and Premium Users who don't have access to that tab even though apparently the previous versions still exist. Additionally if it possible I would like to offer XP users the same functionality although I'm pretty sure with XP only the System files are in the shadow copies.
I looked at MSDN on the Shadow Copy Service and went through all the pages, I also looked at AlphaVSS and AlphaFS and all the comments. I'm kind of guessing that I need to use AlphaVss and AlphFS and do the following?Find out the list of snapshots/restore points that exist on the computer.Mount those snapshots.Navigate in the mounted volumes to the Excel file the user wants to recover and make a list of those paths.With the list of paths handy, compare with some kind of diff program, the shadow copies of the files with the original.Pull out the youngest or oldest version (I don't think it matters) of those shadow copies that differ from the recovery target.List those versions of the files that are found to be different.This seems cumbersome and slow, but maybe is the fastest way to do things. I just need some confirmation that is the way to go now.

I am creating a update member page. I would like the page to auto retrieve the information he or she originally used while registering on my site and display them into the individual textboxes of the update profile page, this is to prevent the hassle to rekey in every individual details and allow the user to edit what he or she wants before it is updated into the database. The problem that I encountered was not able to update the changes in the database. When key in the latest data in address text box and hit submit button, the old data in address text box remains and did not update the database
