Edit Save Open A File Of Own Type
Apr 29, 2011
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.

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?

I am new to programming, I have used vb6 a few times but am now trying to learn vb. net using micrsoft visual studio 2008. I am trying to open a dbf file and then then allow the user to edit the field headings and type of field. I am trying to start off with the basic of just open the dbf file and populate a listbox with some properties of the table such as field heading and the type of field, (ie string, or double) and then later look at how to edit and save the new table.

I want to make a program where I load in a file in hex format and have a number of check boxes where if selected then certain hex values change.
So it would search for offset d5dc and change the last 4 values to 00 E1 F5 05 and then then same again for other check boxes with different offsets set to each one.

I have a need to do some extensive editing on some SGML files. SGML is, of course, just tagged ASCII files. But, I need to convert that SGML to nice, neat MS Word files, with paragraph styles. I need to do extensive searching and replacing. VBA does not have the necesary regular expression support, so, I need to use VB.Net. But, I'm at a loss to do the most basic thing. I just need to know how I can open a Word file in VB.Net.

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]

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 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.
