View 1 RepliesI 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've got an existing asp.net project written in vb.net. Another person has written a user control in c#.

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?
View 6 Replies1.) 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 need to save the results of each search that I run on my database, into an excel file. So it is an iterative process where the new search results are added on as new rows to the excel file in each export.

View 1 RepliesI 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.
Please can you translate the above line of C# into VB.NET?At runtime, I'm trying to update an existing GridView column, as opposed to adding new columns, just before a DataBind()

If the user chooses to save over an existing file, I want to essentially delete the file first, then re-create it and save to it. Basically, I don't want to append to the file. I want to completely overwrite. However, I am just running into all these snags. It basially deletes the file as soon as the savefiledialog box opens. before, it would simply append. [code]
View 13 RepliesI'm creating a notepad application with richtextbox as the editor. I have pretty much all of the funtions I want for the application itself, but I want a code that will help me understand whether it has been saved to the computer already.For example, just like in notepad, where you can open a .txt file, and if you don't modify it, it won't prompt you to save on application.exit(), but if you do modify the file in any way, it will ask you if you want to save, and it will automatically save over the opened file without popping up a savefiledialog.
I want my application to do the same thing, and also with any files that I save. For example, when I save a new file, after it prompts me with the savefiledialog, and I save the file to a directory, on my next "save" not "save as" I want it to recognize where it previously saved the file to overwrite it without prompting me with a savefiledialog like "Save As" does.There must be a code to recognize where it was last saved, or opened, but right now my default directory ("Initial directory") for both the open and savefiledialogs are set to the C:/ direcotry.
