Save And Open File In New Windows Application
May 25, 2011
I am trying to write a code to save and open data that is in my application. My application contains hundreds of text boxes, combo boxes and labels. I have created an array for each set of data, i.e.,
glist(0).store=combobox1.value
glist(0).cat=combobox2.value
glist(0).it=label3.text
glist(0).quan=label4.text
glist(0).total=label5.text
up to glist(89).
Is there a way to write a code to loop through the array and save the values so that they can be opened at a later time in my application? The array will contain Doubles and Strings.

This is probably a pretty novice design question. I'm trying to work my way through a number of requirements and give the users the experience they're looking for.I've written a tool that does big calcluation-type things. It currently consists of a class library and command line tool (separate .NET projects.) We're using an Access database format as the file type because it can keep all the various tables together in one file. A few other items about the application: There are not many users. There are no concerns with scalability. There are not great concerns with updates. Desktop is desired. Not web.Using VB and .NET 3.5 SP1
I now need to develop a GUI front end that will allow typical File/Open and File/Save type operations.Users expect that they can open a file, edit it some, then either choose to save it or close it unsaved without any changes being written back to the file. Saving it would obviously save all changes affecting all tables back to the file.
Does it then make sense to use a temp file for something like a proxy then? To, when a user "opens" a file, copy the source Access file to a local temp file and then use that for the editing session? Then, if the user "saves", copy the local temp file back to the source path?
Update: [tagged with ms-access tag too] Also, I omitted the fact that users would expect typical File / Save As functionality too. I think the design I've put in question in this post is what is traditionally called the Proxy design pattern. Has anyone tried this (successfully!) with Access database files before? Words of caution or advice?

Most of them are for things like this, where I am looping through the open windows in my application and then if I find a certain window I do something to that window:
For Each wnd As Window In Application.Current.Windows
If Found Then
Exit For[code]......
Is that the kind of thing I'm supposed to do to fix all of these type conversion issues or am I going about this the wrong way? Also in situations like that, should I be using DirectCast or CType?

Once a user has selected a file with the open file dialog, how can I handle this action? For example, if the user has selected a .txt file and has opened it, how can it get the data from the file? How can it return the path that the user found the file in? Then, how can it save the file?I know that there is a OpenFileDialog.OpenFile() method, but I am also pretty sure this is not what I am looking for. I have also tried the ToObject method, but I probably messed up somehow.

I have a database file that excel reads just fine but i can't figure out what type of file it is. So i figure the easiest thing to do is open the file in vb.net via an excel object, then execute the save as i have seen 1000 examples but even after i think i add a reference vb still has no idea what "excel." is.[code]

I have been using Visual Basic for about 2 weeks now so I know I am getting in over my head at this point, but times a factor. I have created a user form with around 100 User entered text boxes and pull down menus, tabbed pages etc. I can create a distributable file with no problem. However I cannot find any kind of example, tutorial, etc that will show me how to allow an end user to save the form as "enterfilenamehere.DCP" (for example) and then reopen any .dcp file created in my form application. The only examples and tutorials I can find are how to type text and save it as a txt. format. Could someone lend a complete novice some advice or point me in a good direction on where to learn about saving and opening custom file types?To clarify The user can use my form, But at this point has no way of saving and recalling what they entered in my form. It's a one time use only...not really what I want.

Code that opens image file this code works properly
Private Sub MenuItem4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FromFile.Click
PBDisplay.Visible = False
If OpenFileDialog1.ShowDialog() = DialogResult.OK Then
PBDisplay.SizeMode = PictureBoxSizeMode.AutoSize
[Code] ......
This code is what I am using to save image after it is re sized, It will not save the new image, it saves the old image and the old size. I am using a picture box to import the image into, then I am resizing the picture box and the image. But when it is saved it reverts to the original image.
Private Sub MenuItem6_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Save.Click
If SaveFileDialog1.ShowDialog = DialogResult.OK Then
PBDisplay.Image.Save(SaveFileDialog1.FileName)
End If
End Sub

I can launch Excel with the document I want using VB.Net 2010:
Dim p As New System.Diagnostics.Process
p.StartInfo.FileName = "c: empmyfile.xlsx"
p.Start()
Excel starts OK with the file opened. I edit the file, but when I close it down, Excel doesn't ask if I want to save changes. So it closes and loses my edits.
If I do the same with a text file:
Dim p As New System.Diagnostics.Process
p.StartInfo.FileName = "c: empmyfile.txt"
p.Start()
It opens (in Notepad++), I edit it and close it, and Notepad++ asks if I want to save changes.
I've now tried similar code with a Word document - and that's OK. Also with an OpenOffice Sheet document and that works as well.
This behaviour is happening in Windows 7 with Excel 2010. It works as expected in Windows XP with Excel 2007.
What am I doing wrong with Excel? Is it me?
