Datagrid Save To Database?
Mar 5, 2012Visual Studio 2010, Visual Basic I am able to import a .csv file into a datagridview on my windows form using the code below:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles btnChooseList.Click
Dim fName As String = ""
OpenFileDialog1.InitialDirectory = "c:desktop"
[code]....
My issue is that I can get the .csv data into the datagridview, but I need the user to be able to indicate which column is the "First Name", "Last Name", "Address", etc so that I can add the data to the correct column in the database. The imported lists won't always be in the same column order.The end result needs to be that the data in my datagridview will be altered by the user and then saved to the correct columns in my database.

Sql Filestream - Update A File And Save Changed File Back To Database
Oct 30, 2009I have implemented the filestream feature of SQL Server 2008 in a VB.Net application. I can insert files, and then retrieve/view them just fine. However, I have huge problems trying to update a file. Eg. The user selects a file from the grid which I execute via process.start. If that file is a .txt file, the user may choose to edit it. In case that happens, I need to save the changed file back to the database. So far I have failed to do that.
What I do, is take the retrieved file, copy it (cause i got some errors about it being used), and then Process.Start it. After that, via .NET filestream, I convert the file to bytes and try to update the record. SQL Profiler and a manual SELECT on the varbinary(max) column tell me that the file is updated properly, but the very next try to retrieve it I get an unchanged file.
After that I also tried to update the file by changing its File-System Version, but the file still wouldn't seem to update. Does Anyone have a code sample of how I can achieve this operation? Like 500 sites on the internet have examples of how to Insert And Retrieve the file, but not a single example on how to update. This is how my second attempt of trying to update the file via the filesystem looks like. The code for inserting/retrieving is very similar and it works properly. [Code]

View 4 RepliesUnable To Save Data From Datagrid To Access Database?
Dec 7, 2009I'm currently attempting to save data inputed into a data grid clicking the "save" button. My problem is, I also have another DB opened in the same window that also needs to be saved. The second database is pulled up by the contents of a text box, so there for it has no real Dataset to call on. It looks something like this.
[Code]...
I try to run the update command it always throws the exception "Cannot find table 0" or "Update unable to find TableMapping['Table'] or DataTable 'Table'." I tried declaring the connection the same way as the code above and then simply calling the da.update(ds) but it wouldn't do anything.

View 3 RepliesSave Values To Microsoft Sql Database That Are Profile Properties
Jan 16, 2012I'm attempting to build a website and I would like to save values to my Microsoft sql database that are profile properties and them access them to display lifetime stats or totals from playing my websites games. So I think I'm attempting to use the profile object and I need to save a points total and be able to access that via the current user of the page. You're supposed to then be able to play my simple games and each win or loss should update some of those properties. I've been on this step for weeks on end and have spent over 100 hours not getting a single line of code produced and am running out of options to read, and re-read to attempt this.

Wpf - Catching Which Cell Changed In Editable Datagrid?
Mar 6, 2012I have an editable DataGrid in a VB WPF application. The DataGrid itself has its SourceUpdated property set to my event handler. 2 of the columns in the grid are editable and have their NotifyOnSourceUpdated flag in the Binding set to True. The event is firing properly, but I can't seem to figure out the best way to determine what has changed. The 2 columns depend on each other in that one of them is an item quantity and the other is a case quantity. If the user changes one of them I want to re-compute the other value and update the grid as well as the binding source. I'm sure there are a number of ways to handle this, but I'm curious what is the best way. I could listen for change event on the datagrid, see what changed, set some variables, and then use those in the SourceUpdated event, but that doesn't seem elegant.

View 1 RepliesForms - Checking If Values Have Changed
Jun 10, 2010I'm basically putting some validation logic around an undo button on my form and i'd like to check whether any fields on the form have had their values changed so i can ask the question "abandon changes?". This seems like something pretty standard to me but I can not see how to check whether a value has had its contents changed (without recording a before value and comparing it to the after value which for large forms would be quite horrendous to code).
In the language i used to use we used to walk the object tree (so we dont have to specify each object individually like text box, combo box etc) and check any object that have value-changed = yes to indicate the validation was required.
Application Does Not Save Changed Content
May 31, 2011OK so after a week of aggravating, hair pulling, disaster of trying to figure out what should be simple tasks but beat me down! Ok so I wanted to create a application that would, somewhat manage the users own collection of video games (Lame i know ) you add your games to a listview item, with an image and some sub items, viewing details, using a textbox to search your games... etc i hope you get it
Ok so what i cannot figure out, or find by combing the internet! is how to save all new items the user adds... And including: the item, all the sub items and the picture thats associated with the item.! Instead of posting the code, i posted the application Source code itself here:Source Code , I also started a project here: Codeplex
Later i eventually was thinkin of ading a "wish list" feature where you could add the games you want to get later and also tag it with a release date so when the date comes up, it will let you know, maybe through some alarming way or textbox somehwere... IF you guys want to make it better or fix it! go ahead, i just want this app to save upon EXIT or directing me in the right direction would be VERY VERY much appreciated!
Save Changed Picture Box To SQL Server?
May 25, 2009I have been working on a project. In this project I wish to be able to create electronic signatures. I have perfected the signing routine and also creating the memory astream and saving and retrieving an image. The problem comes in when I retrieve the image from the database. The image being saved does not capture the signature (the changes I've made to the picturebox)
1. I load a small bmp as the template on where to sign with by setting the picturebox.imagelocation to a network share
2. Using mousemove and mouseclick, and draw events I draw a signature on top of the picture box
3. I picturebox.image.save(memorystream) the picture box to a sql server from a button click event.
4. When I retrieve the saved image there are no edits (No signature) only the original image. I am sure that the original image is going in and that it is coming out every time.
My question is thus: How can I capture the signature that I have edited into the picture box. I have tried picturebox.save like I mentioned above and I have tried picturebox.update() but without success. Does anyone know what I missing I think that the answer lies in refreshing or updating the picturebox, but I'm not sure how.
