Is There A Specific Save Command That Updates Access File Permanently
Jun 17, 2010
1.) I dragged my detail view over to the form window to create a bindingnavigator, fields, etc.When I press save on the form, the database is temporairly saved.However, if I save my visual basic project, I lose all the changes I have made to my database.Is there a specific save command that updates the access file permanently?The default command added by dragging over the dataset does not work.
2. My database is accessed with the following string:[code]However, doesn't this mean that the database MUST be placed in that specific folder on any PC? Is there a way to simply build the database into the compile so the program automatically generates the database when installed on anyones computer?
3.) This might be fixed by fixing the previous two issues, but if I compile my program and try to install it, I get an error message "Could not download the application.The application is missing required files."

I am implementing an application in vb.net about a library management system, when I add new record to the database and then close and reopen the application, the record is not there!
I googled the issue and used the text book of this course but nothing beneficial.

I wonder if it is possible to find a specific row and specific columns in data base file (Access) . You see , I am using a DataGridView control to show only SOME of the columns (fields) of a table from an Access file . For example , lets say that in the DataGridView control I only show the following fields :Field1 , Field2 and Field3 .Now , when the user selects an entry in the DataGridView control , I want to insert the text from Field4 into a text box on the form .
The problem , however , is that I don't know how to get the specific row in the data base file and also I don't know how to get the text in column (field) Field4 of that row .One thing that might be important is that the index of the row in the data base file is not necessarily the same with the index of the current row in the DataGridView control . This is because in the DataGridView control the rows are order by the contents in the ID Field .ol .

I'm trying to figure out how to do this as I'm not sure what's the proper way of doing this.
I've got several strings that I want to store/save permanently, even after the application is closed. How should I proceed? Do I read or write from a textfile?

I'm trying to figure out if specific Windows updates are installed so I can install the correct ones.I'm currently checking the WindowsUpdates.log file that is located within the windows directory, but it's terribly unreliable.In my search to find an alternative method, I cam across this blog post. It seems like a perfect fit. Unless you take into account that this is VBScript and their querying Microsoft.Update.Session.what class in WMI that would relate to VB so I can pull the info.

I am writing a text editor program and I have written the new, open, save as, exit menu items but I am struggling with writing the save option.Now I have created the menu itself (well vb did, I just used insert standard items) but how do I code up the save menu option so that it updates the current document or if the documnt has not yet been saved bring up the save file dialog.Here is the code I have so far
Public Class Main
Private Sub NewToolStripButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles NewToolStripButton.Click, NewToolStripMenuItem.Click[code]....
I know I have some finishing touches such as messages and error handling and stuff but at the moment I want to get all the basics working,I think the save menu option is all I am struggling with at the moment.

I am creating a form that creates new users and then updates them to a dataset, I have done this ok, but I am getting a runtime error when I delete a record. Please see below the exception being thrown
"Update requires a valid DeleteCommand when passed DataRow collection with deleted rows"
My code below
CODE:
So I know I need to add a delete command, but how do I write this in code and do I write it in the saveitem click event? I guess I would because the app crashes when I click save to update the dataset.

I have been trying to fix this and make this work for pretty much three days now. I already solved one problem being, I can't use the shell on one HDD and create another file onto a different drive other then the drive that the directory of the application is running in.
EX:
If I run a program that is on the C: drive and using a working directory that is on the C: drive, I can not create a file onto the F: drive.
I got this problem when I was just using Shell(Environ$("Comspec") & " /c then the command")
So I decided to use Process()
Dim p = New Process()
p.StartInfo.FileName = "F:Visual Basic ProjectsCode TestingCode TestinginDebugToolsMediaInfoMediaInfo.exe"

Is there anyway to save a thumbnail of an image, then save it so that, when viewed through My Computer, the thumbnail is displayed for the file. Basically, what I mean is to do something similar to the way you can see a preview of a pdf file, or Microsoft Word file, or Microsoft Expression Design file. I want to be able to open the file's containing folder, then switch to thumbnail view, and the thumbnail will be displayed as the image for the file.

I'm trying to do the following I'm not sure if it's possible using VB.NET. I want to specify default saving point for all files type for example: In my program you choose the path "C:UsersMarkusPictures" for pictures and everytime you download pictures files from website, or using skype or any other program when Save File Dialog opens up (external one not via my program or connected to vb.net just the windows default one) then it will show "C:UsersMarkusPictures" always for .jpg .gif type of files etc...

I have just learned about serialization, and looks very appealing as a way to save application data without much maintenance overhead.But I have one issue that I would like answered before I start coding.If a user saves a project via serialization, and then the program gets an update, say one that might have added or removed a property for an object.If the user then tries to load his previous project with the updated program, since the object now has a modified structure won't it fail to load from the previously serialized data?Would there be any way to recover/convert that saved data to the current object structure?

I am trying to understand how the binding navigator buttons are actually working.
I started by creating a table called "Students" in MS Access,
I then "dragged and dropped" that table onto my VB form after importing the data connection.
When I debug, I click the add new (the yellow plus "+") then I type info into my fields (700_Number, First_Name, MI, Last_Name). (700_Number=Primary Key)
After I am finished typing into the four text boxes, I click save. If I end my program then start the debugger again, the record is still there...it goes away only if I change some of the code anywhere in my program.
Also, I am trying to use the record I just put into my database for another part of my program. I use this line of code:
MsgBox(frmAddStudent.DrByrdsTaskListAppDBDataSet.Tables("Students").Rows(0))
This is just to see if what I am trying to put into my database is actually making it there. Every time I run, this message box turns up blank.

i seem to have a problem when i try to update a certain record in an Access 2007 Database. I have a small Access 2007 database with 1 table which has 3 Columns and several records. The 3 columns are RecordNumber (Primary Key and it is autonumber), FirstName(text) and LastName(text). What i am trying to do in VB 2008 is implement a search form which when you find a record you can update it. I do not have any problems with the search, but i cannot seem to edit any other record than the first one. For example i search for John which exists, if that record is the 3rd record when i try to edit it whatever changes i make (for example change that to James), the changes i make are made to the first record and not the current one. I tried a lot of things but nothing works, here is my code:

I'm using VB2008 express, and I want to save my project: "VBprogram_V1" as "VBprogram_V2" and then make changes to the Version 2 program. But there is no command in the File menu to do it. If I just copy my project folder to a new folder and give it a different name, vb gives me a headache with heaps of errors I don't understand.Maybe "Save as..." is in the commercial versions of VB?
