View 4 Repliessomeone know how to change the name of .tif image after sent a fax??i've these object:
Set FaxServer = CreateObject("FaxServer.FaxServer.1")
Set FaxDoc = FaxServer.CreateDocument(Server.MapPath("fax.doc"))
I wrote a fax program that is using Microsoft FaxServer and FaxDocument on a windows 7 machine. I want to be able to check if the modem that the FaxServer is using is busy. I maybe busy for whatever reason (in use by another program, receiving or sending faxes, whatever). What currently happens, is if the modem is busy, the fax is sent to the Windows Queue and waits for the modem to get done. I don't want that to happen. So before sending I want to check if the modem is in use. I have a couple of things I have already done. But I am having issue tying them together.
I can get a list of ports for the computer and I can get the faxserver devices. But I would like to be able to do something like... take the faxserver device it is using(Com1, Com2, Com3...Whatever) and I want to check if it is free.

I have 2 winforms, one acts as server (ie Winform:Server role) and another one as client (ie Winform: Client role). In my LAN setup, there are 6 PCs and these PCs connected to each other via a 8-port switch and each PC has more than 1 LAN card.
There is one PC running [Winform: Server role] and 5 others running the [Winform: client role]. In [Winform: Server role], I'm using following code to obtain local ip address and port number and the [Winform: Server role] will listen to all incoming TCP requests according to these auto assigned ip address and port number.
Dim Listener As System.Net.Sockets.TcpListener
Dim Client As New System.Net.Sockets.TcpClient
Dim Message As String = ""

I need to clarify my intention. My current approach to my intention maybe incorrect. I attempt to create a 'zero configuration client-server networking' and that is plug & play. The server will know where the client and vise versa. I know there is a program (i.e. MaxiVista) has done that exactly.
MaxiVista has 2 applications, i.e. server and client. Users only need to execute the server application in PC designated as server role and execute the client application in another PC designated as client role. Then the server will be able to find all executing clients in the same LAN.
My intention is just that. Plug and play 'zero configuration client-server networking' within the same LAN.

I want to send On and Off Signals to a USB Cord Connected to my Laptop.Universal Serial Bus, right? In my IDE, I have put a SerialPort Object onto my form. But I don't know how to detect or how to find out at what port number the USB 2.0 Cord is connected to? I wanna start working with Motors and Stepper Mototos with VB.NET. But I fear I am not smart enough to mess with it. I have done many different things with VB.NET, I wans to start messing with Serial Ports, and Serial Communication. It Says COM1, a USB Cord Connected to my laptop is not a COM1.

View 2 RepliesI have a problem with a sql query. Through the query I am trying to search database for any occurrences of string (can be anything) in a column using the SQL LIKE command. The problem is that it works fine for most of the strings say john, jim, ji"m , but does not work when i include the following characters which are ( ' , { , } , and a single quotation mark). MYSQL query takes care of these special cases by putting them in [] block whenever user enters them .But i am getting the following error when i go to query the database using the GetSelectCommand() in VB.NET

I am trying to filter a dataset using a number different inputs, selected by a number of check boxes. I have all the text base rowfilters working, but I can not make the date filter work unless I hard code the datetime into the code. The database is MS Access and I am using VB2008 to show the data. I would like to be able to use a DateTimePicker to set the filter date (without the time part) Also I would need to remove the time section of the datEnterDate. I cannot change the structure of the database fields. Also the datEnterDate is MM/dd/yyyy, because I'm in England I would like to use the format of dd/MM/yyyy if possible

I am attempting to create a game in Visual Studio 2008 that allows a user 10 attempts to guess a random number between 1 and 50. I have a label box in which I would like to display the remaining guesses as they decrement. The code so far appears below.
My two (I am sure very basic) questions are:
1. How would I pass the random integer generated through the Generate Integer function to the AmIRight button's click function? I was trying to decrement the counter each time the "Am I Right " button is pressed.
2. I would also like to evaluate each "guess" when the "Am I right button is pressed. Is it possible to nest a Select Case statement in a For Next Loop?

i wanted to create a random number generator that iterates through a series of number between an upper and lower bound. say between 1 and 100. Basically I want the number generator to pick the numbers randomly and then display them until all 100 numbers are picked without any duplicates. so thats easy I can code that. But what I don't know is how to show those numbers in the order they are generated on a windows form. So i have basically a variable that I will let be changed 100 times (or however many times I want, I don't want their to be a size constraint just using 100 as an example) and each time the number is generated I want it displayed on screen (in a list or something not sure what. Hopefully some type of scrollable list) and each successive number also to be displayed in same format beneath it so that I can see the list in its entirety. What type of form control do i use for that? I could do messagebox.show for each iteration but then user is required to hit ok after each iteration and that would obviously be a bad idea if user selected a large number to work through. Anyways, code isn't exactly necessary just point me in the right direction, i.e.what control (if any) to use.how to format the change in data?

I am trying to make a basic ATM system, iv got all the interface done and I have made the link to my SQL database etc. the part i'm stuck on is how I can run a check to see if a bank card number matches up to the users PIN number. To simulate the user putting a card into the machine I've used a combo box, and that lists all the cards, that haven't been flagged as confiscated (there's a column in my ATMCards table that I can set to true or false) then after the user has selected a relevant card there's another text box where they can enter in their PIN number.
Now what I want to do is, if they chose the card number 1234567890123456 in the combo box and they enter in the PIN 1234 into the text box, then, after clicking the check PIN Button if the pin is correct they need to be taken to another from where they can check their balance etc., and if its wrong they got three attempts after which point i want to flag that card as confiscated.
