Save Ovals On Form And Open Them Back Up?
Sep 28, 2010
What I have is a form I click on and it draws two ovals on the screen. I haven't formatted the second oval yet but is will color itself and place itself with conditions I have yet to create. What I'm stuck on is I need a way to save my work. Then Open it when I return or wish to see what I did. I am using the SaveFileDialog and OpenFileDialog to set/get the file but what I am have issue with is the code needed to save all the Ovals on the page and redraw them. Can one of you give me some guidance? Do I need to create a Serializable Class to draw my ovals to start with and not use the Powerpacks.Shapes?

I have a open and file save dialog which I use to open and save file. There are also some labels in the application. During the time a file is open or saved, the file open /save dialog becomes blurred by the background labels. Is there any way to prevent this? The attached pic is given as an example to explain the dilemma.

I have a Windows form I would like to save the Ovals I created while running the form for use and review later I have been trying the SaveFileDialog but have not figured how to get my data out to the file that is created. I have read about using datatable but there again I'm working with that but need to find how to load all my Oval parameters into the table so I can recreate the current look of the form.

I am making a multi form application in VB 08 and need to program a back button (just like a back button in a browser). The code I wrote loops the back function. For example If I start at from 1 and go to 2 and then 3, I need the button to take me from 3 to 2 and then to 1, but my code takes me from 3 to 2 to 3 because it thinks form 3 was the last form before 2. 'm sure this is simple, but so are my skills
Here is a snipped of the code from form 1:
Public strLastForm As String
Private Sub btnTwo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
[code].....

What I am trying to do basically is open an access query in a datagrid view and then be able to make changes to the datagrid and then save it back to the database.When I try to save:
Me.BindingSource.EndEdit()
Me.TableAdapter.Update(DataSet)
It says that update is not a member of the tableadapter... Why is that?

I am creating a photo hunt game for grades 6-9 in summer camp. I want them to alter an image in paint then create two picture boxes. I want to put in ovals with no fill color to mark the differences in the picture but VB.net won't let me send the images behind the ovals.

I want to creat a photo hunt for 6-8th grades summer computer camp. all I want to do is have them change the image in paint, then load the two images in picture boxes on a form. When I create the ovals to identify the differences in the images, they automatically are behind the picturebox.I can't figure out how to get the ovals to be in front of the picture box. I click the picture box and say send to back but the ovals are still behind the picture boxes. There is no right click on the ovals to send to the front. there has to be a simple answer for this. I also tried putting the images on the background but when I make the ovals invisible, they are not clickable and I cant set the border to 0.This was a no brainer in vb6.0

I have a MenuStrip with File > New, Open, Save, Exit located in a parent form, and a RichTextBox located in a child form.The problem I'm running into is concerned with the destination of the file elected from "Open" and the save.When a user selects their file from "Open", I need it to open the child form and put the text into the RichTextBox.I also need the program to be able to "Save" from a child form, whether it's been brought up via "New" or "Open".

I am wanting to find out how to use the Win32 hooks to allow me to add extra save locations to the save and open dialog box so as to allow as an option for files to be saved directly to a database rather than a file system.I have tried looking online but can't find anything remotely usable for this, the only data on hooks that I can find involves Window operation hooks, mouse, leyboard, and shell hooks, nothing to do with files.

In my project,I used the wizard in VB.NET2008 Express to connect to my database. I have a data connector, adapter, and dataset controls on my form. I have been able to load the information into the dataset, and used the datCustomers.Customers.AddCustomersRow to add a new row to the dataset with information.
I now want to save the updated dataset to the database. I have tried using the adapterCustomers.Update(datCustomers) command to no avail. how to save the dataset to the database?

I am using this code:
Dim Session As Redemption.RDOSession
Session = CType(CreateObject("Redemption.RDOSession"), Redemption.RDOSession)
Session.Logon()
Dim appt As Redemption.RDOAppointmentItem = CType(Session.GetDefaultFolder(Redemption.rdoDefaultFolders.olFolderCalendar).Items.Add, Redemption.RDOAppointmentItem)
To create an appointment, send it as a meeting request and save it as an appointment on my calendar. However, I want to be able to save the GUID of the appointment so my sync routine doesn't recreate it (since I don't have the GUID saved.)

I'm using VB 2010 Express with a local Access DB. I am having trouble determing whether there are changes in a DataGridView to save back to the underlying DB.
The DB has been copied to the project directory and its properties (by selecting it in the Solution Explorer) include Copy to Output Directory: Copy Always, so I know that any changes I make when running a build will disappear on the next build. The problem I'm having is within a run / test session, working with the application.
The Access database has the following connection string, with Application scope:
Provider=Microsoft.Jet.OLEDB.4.0;Data Source="|DataDirectory|Component MI.mdb"

I need to save the form settings, like a save state of the form. Because the program allows the user to add controls. I would like to be able to save them and load them. BTW: The controls are Panels and Labels. BUT! The Panels are a modified version of the control, known as NewComp. This simply allows the user to drag the panel around the form.

I 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]
