Now I don't understand. Do you want to store in the database:
- only some information about the CV
- or the whole document as binary information.
If it's the first one, you set up a table containing fields for each information (name, address etc) and then extract the info from the CV. If you want to understand the CV programmatically, there is no general way to do this.
If you want to store the whole document, use LOBs as I suggested. Refer Oracle LOBs[^] for more info.
The need to optimize rises from a bad design.

As I said there is no general way for this.
If you cannot force the CV to some specific format (like using an asp page), it's just a document.
If you have an idea how you would know what is name and what is address and so on, you can use that info. Otherwise it's just text in some format (rtf, doc, txt etc). So the question is, how would you know for example the name of a person.
Take my name as an example. How would you recognize in the text that it's a name and not for example address or something else? In this forum you can recognize it since it's in sender info so this site forces some information to a specific format.

am trying to draw rectangle but it is drawn just with a single click (with different lengths and widths) also it is going out of pictureBox area But i want it to start from where mouse key is pressed and end where mouse key is released. i think there is something wrong with my quardinate. Waiting for reply.
Thanks

I have a windows service that I'm currently writing that will start automatically when the server that it is installed on is rebooted.
The service will look up some data on a SQL table and then close the database and continue working without opening SQL again.
This should work fine with one exception. What happens if the MSSQLSERVER service hasn't started yet?
What is the procedure to add code to my service to create dependencies that MSSQLSERVER has to be running before my service starts?
Any help is appreciated.

Insted of creating dependencies, can you just check the status of the MSSQLSERVER service and start it if it is not running?
|
|
|
|
|
I thought about that, but I don't want the service to just shut down if it can't find SQL. With dependencies doesn't the server sort of handle the order that it starts everything to make sure a service that depends on another service doesn't get started first?

I'd say you're right. I usually try to take the easy way out. 
Check this out: How to: Code Service Dependencies[^]
It appears there is a ServicesDependedOn property on the ServiceInstaller class.

It worked perfectly! Thanks!

I've been writing an app (desktop) that has information that needs to be passed between forms. I'd like to use an object to move the information about the forms, but it didn't seem too feasible. I did some research online and most people say to use a 'global' module that holds the variables that are common amongst the forms, but there are trade-offs. However they (the articles I've read) won't specify the trade-offs. Is it a performance issue that is caused by doing this? Is there a way to move an object from form to form cleanly?
I'm just curious as to this community's thoughts on the subject. If this needs to move to another forum area, please feel free. I placed it here because I develop in VB.Net 2k5.
Thanks in advance.

x1 = MousePosition.X
y1 = MousePosition.Y
End Sub

[end code]
thanks in advance

It may be best to just create a custom control so that you can manage all the drawing so that it is exactly what you want. The picturebox control is basically only used for displaying pictures and not much else, but a custom control can do what you want and more.

Hello,
You can try the given code.
BEGIN CODE
<br />
Dim MD, MU As Point<br />
<br />
Private Sub PictureBox1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseDown<br />
<br />
MD = e.Location<br />
<br />
End Sub<br />
<br />
Private Sub PictureBox1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseMove<br />
<br />
If e.Button = Windows.Forms.MouseButtons.Left Then<br />
<br />
MU = e.Location<br />
DrawLine()<br />
End If<br />
<br />
End Sub<br />
<br />
Private Sub PictureBox1_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseUp<br />
<br />
MU = e.Location<br />
DrawLine()<br />
<br />
End Sub<br />
<br />
Public Sub DrawLine()<br />
<br />
Dim g As Graphics<br />
g = Me.PictureBox1.CreateGraphics<br />
g.Clear(Me.PictureBox1.BackColor)<br />
g.DrawLine(Pens.Blue, MD, MU)<br />
g.Dispose()<br />
<br />
End Sub<br />
I hope this will help.

Hi everyone,
I'm writing a Windows Forms application that shows movies, images, scrolling text, ... in different panels on a form.
This is the process that I do:
1) I create the different panels on the form
2) I create an object of another class (MyClass), set some properties and call the start method of the created object.
3) The start method creates an instance of a control to show the movie, image, scrolling text, ... and add this instance to the right panel.
--> Step 2 and 3 happens for each panel on the form.
I encounter one problem when I use this process. I see that the scrolling text waits for a short moment when the movie starts to load, after it is loaded the text is running again. I thought that I could fix this problem by using threads.
So I changed my process:
1) I create the different panels on the form (MainThread)
2) I create an object of MyClass and set the property where the movie, image,... has to run in (so in which panel)
3) I create a new thread (MyNewThread). When the thread starts, I execute the start method in the MyClass object. This start method makes a new instance of a control. To add my instance of the control to the panel, I have to invoke my panel. Which results that I'm back in the MainThread. So the control, plays again in the MainThread.
So this process don't solve the problem about my scrolling text.
I want that the controls are running in a different thread than the MainThread. But I think this is not possible, because the main form is running in the MainThread and everything that I want to add on the form has to be done in the MainThread by using the invoke. I'm right?
The only thing that I want is that the instance of a control in a panel is working on his own. So that loading some things in one control does not have an influence on another control.
Has someone any idea to do it?
Thanks in advance,
Kurt.

Move your scrolling text to its own control that, itself, is threaded.

Hi Dave,
Thanks for your answer. We did what you have written. Our scrolling text was already a control, so the only thing that we had to do is adding a thread that does the work to scroll the text. But we have noticed that the OnPaint method (draws the text, and is executed by the Paint event of the form) is executed in the MainThread and not in the new thread that we have created. So the text is drawed on the form in the MainThread. The OnPaint event is triggerd by calling the invalidate method. The handler that says what to do in the MyBase.Paint event is also set in the new thread. Is it possible to execute the OnPaint method in our new created thread?
Thanks in advance,
Kurt
