A library for sending SMS in VB 2010 Express

[Maniac345]

Hi, not knowing where to post my first greetings I do it here .. I registered with the site because wandering around the net I found interesting and why I would need, if possible, your help .. I'm looking, self-taught, to make a small program with visual basic 2010 Express, to send SMS through PC by connecting via Bluetooth to a mobile phone .... I have already "put down" a little bit (if you can attach) on how I'm going to do it .. I found a site where you can buy a DLL library that lets you send and receive SMS .. But I do not know where to start with these types of control ... you think I should start with something simpler, but I've done a little bit beyond the classic "hello world" ... and then are attracted to this challenge ... succeed in doing this small program is now my goal to be able to consider a real program ... I'll need some tips that I hope to find here ... maybe comment on the why and wherefore I have to write certain lines of code to get what I'm looking for ... I'm not looking for someone who makes me the program because it does not seem to me more than all right and counter-productive for me in that way would not understand and learn a damn thing ... I hope not to have lasted far too long even though I am almost sure of it now already .. and proper forum to hear from you all .. Also, I'm trying to attach a screenshot of the software I want to achieve but the file size are larger than 25k and if you reduce it below this limit does not see anything ... help me please.

Welcome to the forum TechArena.. Without going on about your preparation and what we want to achieve, I answer to your question: I think (I hope ..) that you know what is a "DLL", in any case you should ask for the documentation to understand which functions have and how to use them. This method also includes the installation of programs on my phone? If not, make sure everything sent to the cellphone - in this case the modem of the mobile phone - a command via bluetooth to read / send SMS.

The truth is that I know really well what a dll ... I think it is a set of instructions that can be given or something. I came back on the site (do not write it because I do not want published findings ..) to review and there talk of an ActiveX component (DLL) that can be used during the development of a software .. I posted in the other section because it deals with VB.net programming in general .. Thanks for moving it in the most appropriate
From what I understand you do not need to install anything on your phone .. passing all commands through bluetooth (in my case or in any communication via COM) or AT commands. As I said a little something I've done .. I created a form where I put in which:

• A TextBox where I intend to insert the text of the message (limited to 150/160 characters)
• A button that I "clean" the message textbox
• A series of checbox corresponding to a preset list of recipients, in the sense that "inspiration" only those who want to be included as a recipient, perhaps a little laborious when developing the software but I felt comfortable then in the end use. When a recipient selects the character's name changes color to get yourself more visible in the list
• A button that I select all users, even here change color
• A button that I uncheck all the users and the font color back to default
• A button that makes me start sending the message
• A read-only textbox that brings me a wild sort of history of what's happening (modem status, list of recipients to whom the message is send)
• A button to exit the program.

Then maybe later if I can enter a command that I care about all the contacts on the phone You can also choose a recipient from there but did not insert it as a checkbox. For now I am able to get a few things ... the selection of recipients, the change of color, selection and return to the default color, emptying the message in the textbox, the output from the program .. almost anything that concerns the actual delivery of the message .. Could you tell me something to read or see to understand a little more? or give me some guidance and explanation then?

You should consult the documentation for the library (ActiveX) that you have decided to use ... usually at the site or in the installation folder the manufacturer offers a series of examples written in different languages supported. And as you said you have to look the documentation for your ActiveX, otherwise it is impossible not to exploit knowledge of its functions. You've been very clear in the description (not bad every time someone is ..), and at this point I ask you: are familiar with AT commands? You know in fact that in communications "simple", the bluetooth is "seen" as a serial port, you just need to identify which port is assigned, give an example:

• I see that the bluetooth is bound to port COM2
• by controlling the class or just send my data (ie the various AT commands) to the COM2
• my data is sent via bluetooth (and make it to the device connected to the PC via bluetooth)

Thank you very much, for now you have been clear in information .. now it's me start applying and try to do something ... I will try some examples on the Internet on serial communication and a complete list of AT commands (.. do not know them very well ..) and then after a few test will come back to "bother". I could install a virtualized XP but after you mess with the COM ports .. I think see if there is something similar to Seven. I tried a list of AT commands, connected the phone via bluetooth and something works .. I hope to find a list of all existing AT commands and to other evidence and then try to figure out what to do with VB instead CONM Hyper Terminal ... We will study up a bit.
