• Sylvain Arene Too many arguments specified error in stored proc

  I'm getting a 'too many arguments specified' error when I call my stored proc. I've assigned the stored proc to a SqlDataAdapter and a DataSet which is called when the SqlDataAdapter.InsertCommand is called. I've checked the numbers of variables and I can't see where there is a mismatch in the number of arguments being called. I assume that this error has something to do with how I am retrieving the SQL autonumbered identity column (CitationID) with SCOPE_IDENTITY(). If someone could look over my code and let me know what I'm doing wrong, I would greatly appreciate it. Stored Proc: ALTER PROCEDURE tbl_Citations_AddNewRow @CitationType nvarchar (6), @ARTFlag nvarchar (7), @Title nvarchar (1000), @PublicationDate date ...Show All

• Birendra Exception: DataTable internal index is corrupted: '5'. on ...

  Hi, I have a problem with bindingsource component in framework 2.0. I have a combobox bound to a bindingsource which is also bound to a dataset with 2 related tables and a datagridview bound to the same bindingsource. What I want to do is : When the selectedindex property of my combobox changes, the corresponding cell value must be changed in the datagridview. But although the value in bindingsource changes, datagridview does not display the new value. That value is displayed after I move the mouse over that cell and make it invalidate its region manually. Another error I caught is the one that you can see as the subject of my post. I do not know why i have that message when I try to change the property of ((DataRowView)mybindi ...Show All

• Leroyg displaying an image from the internet in a picture box / label?

  Is there any way i can have a picture box and display an image in it that is hosted on the internet say for e.g. - picturebox1.image ( http://www.website.com/image.jpg ) any help or direction would be great, i would use web browser but i cant get rid of the boarders. I suspect that the reason you are having a problem using the code when pulling the URL from the textbox is that you are trying to assign the URL to DownloadData instead of passing it in as an argument. Try this instead: Dim buffer1 As Byte () = wc.DownloadData(textbox1.Text ) Alright... try this one on for size: Imports System.IO Imports System.Net ...

• Davids Learning Securing SqlConnectionString

  Hi, I want to secure my confidential data in database. So i have written a function. It will initially changes the user's (which i have created for data access) password and gives me the encrypted one of the new password. So the developer won't know the password. To get the connection i have to pass the username and the encrypted password into one module which i have written. It will decrypt the password, creates a connection and returns the SqlConnection object. Here i am facing the problem. After decrypting the password i have to attach the username and password in ConnectionString that can be readable by the developer. How can i overcome this. Please advice.

• santaclaus Process.GetProcessesByName and case sensitivity/uppercasing of process name

  When listing processes using Process.GetProcesses() I sometimes see “notepad”, and sometimes I see “NOTEPAD”, sometimes I find process named “iexplore” sometimes “IEXPLORE”. (This is consistent with Task manager displaying “notepad.exe” vs “NOTEPAD.EXE”.) What is even stranger the following code ProcessStartInfo startInfo = new ProcessStartInfo(“notepad”); Process result = Process.Start(startInfo); Resulted on couple of occasions with “NOTEPAD” process being launched as opposed to “notepad”. Unfortunately, using Process.GetProcessesByName(“notepad”) will NOT return any hits for processes with process with name “NOTEPAD”. This looks to me like a bug, if process name should be either consistently case sensitive or not, if it i ...Show All

• solutions accessing a properties PropertyInfo

  I want to access a property's PropertyInfo without knowing it's name, I can do this if an accessor invokes another method via putting the following code in the invoked method. string caller = new StackTrace.GetFrame(1).GetMethod().Name; string pName = caller.Name.SubString(caller.Name.IndexOf('_')); PropertyInfo info = <this>.GetType().GetProperty(pName); As a result the same method can be readily invoked by accessors of different properties and the method can do its work based on the property name, type, custom attributes etc But I also want to do something similar in an associated method that is not invoked by an accessor - but by a method in another class, which has an instance of the properties declaring class.
