You get the original image size from the dimensions of the image and the PixelFormat, but I think you are interested in the file size which you can get a variety of ways from IO. You change the encoder quality by the Quality EncoderParameter. There is no direct relation between file size and encoder quality other than lower quality results in smaller files.

Hi,
I want to write some values into HKEY_CLASSES_ROOT but when i try to do so i get the message that i don't have the permission. (Using Vista). So, is there any way to let my program run as Administrator, without the user right-clicking on the file and choose Run as Administrator?
Thanks in advance,
--Zaegra--

Nope, there's not a way to run an application as admin without having to log on with an admin account. You need to write registry values to a different part of the registry (HKEY_CURRENT_USER in stead of HKEY_LOCAL_MACHINE) or use .NET's isolated stored functionality which I'd prefer...
|
|
|
|
|
I would've done so, if only I wasn't registering a filetype, which has to be stored in HKEY_CLASSES_ROOT. So there is no way doing this, without the user right clicking on the file and run as administrator?
|
|
|
|
|
In that case, you need to register file type (i guess for file type association) during setup and not from within your application. Else you should require the correct permissions and not run the application if the user doesn't have sufficient rights..

Good Morning All
I have a Login(frmlogin) form and an MDI form(frmmain), i have a Function that check against the DB if the username and password exists and if they do, it will return '1', if it ruturns '1', i will know that the login is valid, and i will have to Close the login form and show the main Window. in my Application "frmlogin" is a Startup form. i have written the explain procedure like this.
Dim frmmain As New frmmain<br />
<br />
Dim strusername As String = txtusername.Text<br />
<br />
Dim strPassword As String = txtpassword.Text<br />
<br />
Dim obj As New BLL.Client<br />
<br />
Dim bl As Integer<br />
<br />
Try<br />
bl = obj.Check_Login(strusername, strPassword)<br />
<br />
If bl = 1 Then<br />
frmmain.Show()<br />
<br />
frmLogin.ActiveForm.Close()<br />
<br />
Else<br />
<br />
MessageBox.Show("Invalid Login")<br />
<br />
End If<br />
<br />
Catch ex As Exception<br />
<br />
MessageBox.Show(ex.Message)<br />
<br />
End Try
This is the code in my "frmlogin", My problem is that when the login is Valid, The frmmain window is Shown, but the login does not Disappear.
What is the Problem?
Thanks

Hi,
U can't close the statrup form so my suggestion is
Make the Mdi form as a startup form and on load event of mdi open the login form if login is authorized then ok other wise u can end the application or prompt that enter valid user name n password

The Problem was Solved this way
I used a Main method in a module as my startup object:
Friend Module Startup <br />
Public Sub Main()<br />
Dim loggedIn As Boolean<br />
dim login As New frmlogin<br />
loggedIn = (login.ShowDialog() = DialogResult.OK)<br />
If loggedIn Then <br />
Application.Run(New MainForm)<br />
End If <br />
End Sub <br />
End Module
my login form would look like this:
Dim strusername As String = txtusername.Text<br />
<br />
Dim strPassword As String = txtpassword.Text<br />
<br />
Dim obj As New BLL.Client<br />
<br />
Dim bl As Integer<br />
<br />
Try<br />
bl = obj.Check_Login(strusername, strPassword)<br />
<br />
If bl = 1 Then<br />
<br />
Me.DialogResult = Windows.Forms.DialogResult.OK<br />
<br />
Else<br />
<br />
MessageBox.Show("Invalid Login")<br />
<br />
End If<br />
<br />
Catch ex As Exception<br />
<br />
MessageBox.Show(ex.Message)<br />
<br />
End Try
Now the login dialogue will be dismissed if and only if the user either successfully logs in or cancels the operation. If the user does not successfully log in the app will exit without ever creating an unnecessary main form
Thanks

just try Hide instead of close and before that open the MDI. So the application will continue to be in running state or else the application may close

Hi Frnds..
I hv developed a Bill Contract Software in Vb.Net 2005(Windows application) , using vb as a language and msaccess as backend. I want to store all the data in the server. So i hv copied msaccess file to my personal domain inside wwwroot folder.
Now i dont want to store data in my PC. It should be stored in the server directly. Can anyone tell me what is the connection string for that...
Thank you...

Yes, it's a path to the mdb, across the network to the server machine.

hi
try looking in here...http://www.carlprothman.net/Default.aspx?tabid=81

hi,
simply create a log file, which store the path of your database.
Let me explain
first of all , make a form which ask from user for database path and set this form as startup form. Now at load event of this form check whether logfile(path.txt) is exist or not and perform action according to condition. I use following code in most appliction
If File.Exists(Application.StartupPath & "\Path.txt") Then<br />
FileClose(1)<br />
Dim s As String<br />
FileOpen(1, "path.txt", OpenMode.Input)<br />
Input(1, s)<br />
Dim FilePath As String<br />
FilePath = s<br />
TextBoxSetDatabasePath.Text = FilePath<br />
If File.Exists(FilePath) Then<br />
FilePath = FilePath.Substring(FilePath.LastIndexOf("\") + 1)<br />
If FilePath.Trim.ToUpper = "YOURDATABASENAME.MDB" Then<br />
DatabasePath = TextBoxSetDatabasePath.Text.Trim ' DatabasePath is global variable<br />
LoginForm1.Show()<br />
Me.Close()<br />
Else<br />
msgbox("Wrong database file. Please choose correct database file")<br />
End If<br />
<br />
Else<br />
msgbox(("Database file not found. Please choose the database file.")<br />
End If<br />
Else<br />
mdChecking.Prompt("Database Path not set. Please choose Database file.")<br />
End If
use databasepath varible value in connectionstring.
for prompt user to pick correct database file use following procedure
Try<br />
<br />
If TextBoxSetDatabasePath.Text <> "" Then<br />
If Not File.Exists(TextBoxSetDatabasePath.Text.Trim) Then<br />
mdChecking.Prompt("Incorrect database file. Please choose correct database file")<br />
Exit Sub<br />
Else<br />
Dim FilePath As String = TextBoxSetDatabasePath.Text.Trim<br />
<br />
FilePath = FilePath.Substring(FilePath.LastIndexOf("\") + 1)<br />
If FilePath.Trim.ToUpper = ""YOURDATABASENAME.MDB".MDB" Then<br />
DatabasePath = FilePath.Trim<br />
<br />
'If File.Exists(Application.StartupPath & "\path.txt") Then<br />
' File.Delete(Application.StartupPath & "\path.txt")<br />
'End If<br />
Dim s As String<br />
FileClose(1)<br />
s = Application.StartupPath & "\path.txt"<br />
FileOpen(1, s, OpenMode.Output)<br />
WriteLine(1, TextBoxSetDatabasePath.Text)<br />
<br />
FileClose(1)<br />
LoginForm1.Show()<br />
Me.Close()<br />
Else<br />
msgbox("Wrong database file. Please choose correct database file")<br />
End If<br />
<br />
End If<br />
Else<br />
msgbox("Database path is not set. Please choose database file")<br />
End If<br />
Catch ex As Exception<br />
MsgBox(ex.Message, MsgBoxStyle.Information, Me.Text)<br />
End Try
hope this helps

Well, you have a small problem. You can't connect to an Access database on the other side of a web server. Access is a file-based desktop database, not an SQL Server. It will only work if the user running your app can see the database file through a Windows Share, AND the user has read and write access to that share. Normally, noone gets those kind of permissions if the file is in the wwwroot folder or below.

Hi,
For "DatetimePicker" control, I gave format as customFormat(MM/dd/yy hh:mm:ss).
When i run the application for first time it is working fine (displaying current date and time), but when i select another date the time is not updating.
Please advise me to achieve this or any other control for date and time.
|

You'll have to explain this. Since you just changed the date in the control, why should the time update?? You haven't changed it in the control, or have you??
|
|
|
|
|
your question is little bit confusing. it shows the time for the current date. how would you expect to get the time from the past or in future to display with the date you have given as input. have you done something with time or have any link between the date and time
thanks,
