How To Declare A Button Variable social.msdn.microsoft.com

I am working on an alarm system software, which is SMS-based. I am using a GSM modem to receive the SMS when a client's premise security devices are triggered. The types of SMS text received will be like for e.g. "fire alert"(when devices triggers), "fire clear"(when devices are 'reset'). My program can detect real and false alarm, it works this way, i will input a premise site-map on a picture box at the main GUI, i can then create buttons at run-time and drag them to the respective position on the map. The buttons created have their text set as the client's block number referred to the database. So basically, a button represent a client. When a device in the client's premise is triggered, a SMS will be sent and my GSM modem will receive it, process the SMS and the button representing the client will start 'flashing' showing that the client's premise is under danger. Then when the button is clicked, which acts as an acknowledgement, will display the client's information on labels and turning that specific button to red color. Finally, when the device is 'resetted' in the client's premise, it will send another SMS to my GSM modem, after processing, the button will be back to normal. But my program has detect false alarms also, the first part is similar to mentioned above, client's premise security device triggers, SMS sent, SMS received by GSM modem, process SMS, button 'flashing'. Secondly, if the alarm is false, it will be automatically 'resetted' or the client may 'reset' it, then a SMS will be sent to my modem, turning the button to 'flashing' green in color. when 'acknowledged' will display the client's info and the button will become normal. The problem here i am facing is during the processing of the SMS, because the real and false alarms both will receive the 'clear' SMS when during some stages, but the functions are different and of course the 'checking' for both functions will be different too. The problem occurs at the checking process whereby the 'btn' variable is not detected.

MSComm Incoming Data Detection www.vbforums.com

this one requires some l33t skillzi have built an SMS gateway that succesfully receives SMS , processes them and sends out reply data to the originating number.however, when the load gets very high, usually around lunchtime, i occasionally get collisions when trying to send an outgoing SMS reply and the modem is processing an incoming SMS.i use MScomm_OnComm to receive the SMS from the simcard on the GSM modem, using a poll delay every few seconds. OnComm does not fire (i think) unless i specifically check for new SMS messages using AT+CMGL="REC UNREAD". upon OnComm, i flag a boolean value that holds outgoing SMS at_commands until the receiving data has been processed.now, this method works fine 99.5% of the time. but when the incoming load gets too heavy, i get a collission. an example of this would be when you use a mobile fone to send out an SMS and there so happens to be one coming in at that very instant : you get a Message Sending Failed notice on your mobile.is there any way to check the modem for incoming activity, especially if i just checked for unread sms messages before sending the outgoing, but none are detected as during that milisecond, the incoming one had not been fully received by the simcard/modem .i am at my wits end, i've even tried putting in two boolean locks to try and catch the situation but have failed so far. whats worse , the gateway has already gone live and i've only recently detected the problem. could not simulate beforehand using just my one cellfone hitting the modem.please help. TQi can post code if necessary. i've gotten desperate enough to not bother about source code proprietorship. i'm also willing to contract anybody who can look at the code and figure out a solution.

Error Handling www.xtremevbtalk.com

I have made a SMS Server application. I works in this way:1. Some program write a message in a database in the "incoming" table.2. every 10th second my sms server checks the incoming table. If any messages they will be send with a gsm modem.3. sent messages will be moved into the "sent" table.My problem is that if the database is stopped, the app will return an error whenever it tries to connect to the database. Therefore i have made an "on error" statement which looks like this:Errhandler:wait 60 'a function i have made to wait x secondsgoto getsql 'a label i have made just before i get the recordsetThe first time the error occurs the errorhandler works fine, but the second time the program crashes and says that my mysql database is gone.Why can't the errorhandler catch the error the second times it occurs in the same function?

Can you give some kind of information,in Internet about MMS with AT comands or with Vb.net...(I´m tired of Look for this information, but with no results} ) Thanks for all... Have a good day!!!
