VS 2010 - Create A DDE Server, Windows Form, In VS 2010/11
Apr 20, 2012With a Windows form that I would like to be a DDE server. I know that DDE is not natively supported in VS 2010/11 so I'm using the NDde.dll to add DDE functionality to this program.
Objective: Create a windows form to act as a Pop-up notification that has a textbox field. This textbox field must be selectable in order for users to copy a text string to the clipboard and paste into another program that does not support DDE.
Overview: A phone system has an on-screen agent program that triggers a pop-up form, the DDE Server, when an incomming call is presented. When the agent accepts the call the agent program, acting as a DDE Client, registers a DDE session, Application=phnserver and Topic=callerid. Then communicates an "OnExecute" command to the DDE Server followed by a number string. This string should be presented on the pop-up form in a text box. Once the call is completed the agent application will issue a command to close the pop-up form.
Below is my current code.

I also need the ability to add data to the database for users registering for the first time. The SQL server will need to be able to access the SQL Server databases remote via WAN.

View 3 RepliesVB 2010-Access Database Without SQL Server
Nov 5, 2010I just started learning VB 2010 through a book. I'm learning vb to design a program which can manage customers of a small company as a homework. It'll store data (Company Name, Phone N. and Adress) at an Access Database. (I'm using Access 2007)
I have a little background with programming but none with databases. According to the book there is no way I can delete, add or update a data from an Access Database without installing SQL Server or Express. But this program should work at a computer which may or may not have SQL server or MS Access (Any computer with Windows OS).
After a little digging only thing I could find was Walkthrough: Saving Data to a Database (Multiple Tables) from MSDN and did every step and at the end, I can delete or add rows and change values of the cells but cannot save them (when I click save, close the program and re-open it, changes are gone).
I don't get that how can I view all the data from database without SQL server but can't save changes to the database file without SQL Server.
Is there a way to do this without SQL Server? If so, can you give the right code for the MSDN Walkthrough's Save button? Or point me to a page where can i learn the right code?
VS 2010 - How To Insert New Row Into SQL Server Table
May 8, 2012I'm trying to insert a row into a SQL Server table.
Using this...
cmd.CommandText = "INSERT INTO MyTable (firstname, lastname) VALUES (@firstname, @lastname)"
cmd.Parameters.AddWithValue("@firstname", "bob")
cmd.Parameters.AddWithValue("@lastname", "jones")
cmd.ExecuteNonQuery()
I get an error saying:
ERROR [42000] [Microsoft][ODBC SQL Server Driver][SQL Server]Must declare the scalar variable "@firstname".
But if I use this...
cmd.CommandText = "INSERT INTO MyTable (firstname, lastname) VALUES (?, ?)"
cmd.Parameters.AddWithValue("@firstname", "bob")
cmd.Parameters.AddWithValue("@lastname", "jones")
cmd.ExecuteNonQuery()
...it works fine. What do I need to do to make the first example work? I don't understand what the error message is telling me. How do I declare a "scalar variable"?

VS 2010 Rename Files On Server, Via FTP?
May 21, 2010A while back I asked about going beyond basic FTP upload/download on this thread, and the response I got about using FtpWebRequest was very helpful. Now I'm looking at something that doesn't seem to be offered in FtpWebRequest: renaming a file on the server.
My situation: several times each month I update MyConfig.csv on my website. This file is generated on my computer by Excel to control who can access which files on the site, and it runs a bit over 1 MB. The scripts on the server parse through the file to keep things running smoothly. Given that the file can take some time to transfer, I typically will upload NewMyConfig.csv to the server with a commercial FTP program, then when it is in place I rename the existing file to MyConfigBackup20100521.csv and then rename NewMyConfig.csv to MyConfig.csv. This way, if there is a problem with the upload, everything keeps running smoothly because the existing MyConfig is undisturbed, and the window when a customer might get an error from the scripts because there is no MyConfig.csv is reduced to a couple of seconds between the two rename operations.
Now I'd like to automate all of this to happen with a VB program, but it looks like FtpWebRequest only allows you to rename directories, not individual files, on the server.

B) Scan those IPs for a specific open port
