Hi there, We are making our software using: - OECAPICOM v. 3.4.0 - Delphi language - MDI-form application What we are doing: - Every time our software creates a new module, it loads on it a DLL which one we pass market name and Time frame as parameters; - inside of the DLL, in order to optimise the code, we use some threads how many are the values we want to get from the client: e.g.: Lastprice, Working orders, etc. -in one of these threads we manage OnPriceChange event. - into DLL we have a private variable TOECClient type; at OnShow we put the follow code: "ourvariableTOECClient" := OECClient (OECClient is defined into the Host) .... .... After then, we create the thread to manage the price-change, putting into the thread the client as we made from host to DLL. All works fine... but... when we open a second form, which creates a new istance of the same DLL, that happens: - the last DLL works and the first one stop to receive the values. So then our questions are: 1. Is it correct how we drive the client from one DLL to another? 2. If yes, where we are wrong? 3. Does It exist a better way to manage contracts in different instances of the same DLL? 4. We have notice that when two threads are working and in all of them there's the same event... only one works (the last one...), the first one is stopped... WHY ? Best Regards Pietro Fucci |
