<0> the second one is how you use it in the exe
<1> ok
<1> done
<1> result = j.SendOutput("eef") >>> compiler error , expected function or variable
<2> Here's what you're going to have to do
<2> in your DLL, reference MSCOmm
<2> Keep a private variable that will hold the instance of the MSComm object
<2> Provide an initialization routine to instantiate, and setup the MSComm object
<2> Create a public property that will return the private instance variable
<2> Provide a dispose routine to close the MSComm object, and set it to nothing and such
<1> Teycho : kindly slow down
<0> beginner123: read a tutorial about writing DLLs
<0> beginner123: because you're either going to read a prewritten one, or you'll end up (maybe) receiving one from us anyway
<1> on my dll , project / prefrences / Ms comm.ocx <<< so now i refrenced mscomm on my dll
<1> Smirker : i dont know ...
<1> Teycho : how to keep private variable hold the instance of mscomm object ?
<0> beginner123: www.google.com search for: vb6 dll tutorial
<0> beginner123: read and learn.
<1> ok
<3> http://freelance-job.blogspot.com/2006/11/how-to-win-your-freelance-projects.html
<4> freelance is for pansies
<4> paidlance is far better
<3> paidlance ?
<0> lol
<0> beginner123: don't private message me =\
<1> ok
<1> Smirker : can u provide me a link for write basic dll ?
<5> static blargh as string, this one can hold what 2^32? ~2 million/billion characters, yes?
<6> about 2gb
<6> (unicode)
<5> mm
<5> Iam trying to figure out why suddenly my packets ends up incomplete.
<6> statics are inefficient too
<5> An overflow of the string is not in the question.
<5> Ok?
<4> how do you know they're incomplete?
<5> wsckbuff = wsckbuff & .GetData in _DataArrival
<5> And each string I send, i end with a nifty control code, or whatever you wanna call it..
<5> It works.
<5> But after a while I ends up getting corrupted packets when I am parsing them out from the buffer
<5> I end each packet with chr(1) & chr(1) & chr(1) & vbCrlF.. Should be safe enough, since I only work with plain text.
<5> All packets follow a nice structure of <Header>header stuff</header> <body>...</body>
<5> When I start up my 3rd node (loop exists, but packets gets dropped when they should), I start to get incomplete packets.
<5> Or they start in the middle and suc
<5> h
<6> u strip the 0x1 from wsckbuff before looking at it?
<5> 0x1?
<6> chr(1)
<5> Ah, no. I simply check; instr(string,chr(1)*3) and if its exists, ret=left(string, the len(chr(1))
<5> Ah.
<5> mm, like that.
<5> Then right() to remove that part I just took out
<1> Smirker : i seeked for a website talking about using the OCX on the DLL file , i faild on that , please guide me
<5> bigAl, I will try to hard test my getdata func.
<6> if this isnt streaming, why not include the length instead of a terminator
<5> Wouldn't that be kinda the same thing?
<5> And since the packets can get split, its not 100% sure the len value would always be complete and present.
<6> just seems simpler if you know in advanve how much data ur gonna be getting
<5> Harder the way I see it.
<5> But still, either way works.
<5> I tested now, inserting a string with 1000 packets, each ending with my control code. And then retrieved them one at a time. I got back 1000 strings.
<5> So that part should be working.
<5> humm... Cool
<5> bah, nm
<5> okey.
<5> Well, the infinite loop problem should be one problem =)
<5> Might be what starts it. And overflows something
<4> packet splitting is entirely normal
<4> i thought we'd discussed this?
<5> Yeah
<5> Yes
<5> That part works.
<5> But I see that the second I start up the 3rd node, tons of packets go round and round... Will have to fix that first.
<5> My packet ID functions that are to remember each packet ID aint working it seems.
<4> *shrug*
<4> i have no idea how your handling system is designed
<4> which seems to be where the issue is
<5> mm, I am looking into it now.
<6> take the petty cash and fly to mexico!
<1> Teycho : i reached good level , now i have only one error , which is when i type dim mycomm as test123.MscommCl*** , then set mycomm = new mscommcl*** << it gives me error type mismatch .. can u give a look into the code , i paste into the link nomorepasting ?
<1> pasteID=74035
<4> how about = new test123.mscommcl***?
<1> Doh_ : same error type mismatch error (13)
<4> could be an error in the cl*** itself
<2> Step through the code, including the code in the DLL and find exactly which line is erroring
<4> if youre still developing your dll, add it to the project group
<1> i cant find any problem into the code , kindly can you give a look into it ? pasteID=74036
<2> And likely neither will we.
<2> STEP THROUGH IT
<2> set a breakpoint, and execute every line of code individually
<2> Find exactly which line of code breaks
<4> i told you
<4> the code error might be INSIDE CalTest123 or MSCommCl***
<4> and i told you to do test123.CalTest123
<4> if thats how you dimmed it
<2> And how do we know what any of those variables are, without knowing the code in the cl***?
<5> amagad!... Such a small typo, after fixing it, it seems to be working nice
<4> jack***
<5> Indeed
<4> JACK***
<2> that's it, BlackWand, your daily allotment of oxygen isbeing reduced.
<5> meeeeeh
<1> i give u the code of the cl*** i did a trace , i am doing hard ... still have the same problem i did what u told Doh_ i am still have the error i swear
<5> Doh_, Yes, I deserve it.
<4> beginner, how are you 'tracing' the code?
<4> did youa dd the dll project to the project group so you can step right through the code?
<1> this code available on a site friend bigAL gave me the site , and i download it from there , it works fine when i run it
<2> That's great. but did not answer the question
<1> guys i dont know how to add it into a group ...
<2> Using code you do not understand is going to cause issues. Perhaps you should have looked into what the code is doing more, and looked up a few things?
<2> A solution holds multiple projects
<2> You have two projects, yes?
<1> i looked at it .. i understood how the property of mscomm going on ...
<2> The EXE and the DLL?
<1> Teycho yes
<2> Open the EXE project
<1> opened
<2> Then, goto File > Add Project, and add the DLL project
<2> Now, both projects exist together
<2> Reference the MSComm thing from the project, not from the actuall .dll FIle
<2> That will allow you step through the code, line by line, in BOTH projects
<2> There is an error in the DLL. Until you step through the code in the DLL you will not find the error.
<1> it gives me the following error 'Caltest123' cant be public in this type of project , the item has been changed to private
<4> you probably added the cl*** to the project
<4> not adding the project to the project group
<1> things are complicated .
<2> Yes they are
<2> That's called 'programming'
<2> Do you know what a breakpoint is, and how to step through code one line at a time?
<1> yes i know
<2> Then use them in the DLL
<2> Find out what error is occuring in the DLL
<1> on the dll no issue ... it gives me everything working fine ...
<4> how do you know?
<4> just because there were no compiling errors doesn't mean there are no runtime errors
<1> the yellow light p*** all the lines
<1> Doh_ : i will start over
<1> now i will start from the zero , 1- the file which i downloaded is an exe file , but it has cl*** named MScommCl*** .cls . 2- i will open a new project DLL active x , add file MscommCl***.cls to the project .
<1> 3- i will make the dll .
<4> no
<4> dont make the dll
<1> ok
<4> wait
<4> why do you need it in a dll?
<1> ok
<4> is there a specific reason/
<4> ?
<1> Yes Doh_ , i need in dll , i want to use it on oracle form . as it is required by a customer.
<5> 42
<1> can i now add it in the dll project ( new dll project ) ?
