(_ [] X) ... You know the things a user clicks on to iconize, restore, or close a "window" on the child documents in my MDI application?

"Dirty hands lead to important discovery..." - Thomas Edison ActiveX Control Question Shayna25-Apr-02 6:39 Shayna 25-Apr-02 6:39  Hello, Everyone Currently I am developing an ActiveX Control that is going to be used in MS Word. A userform (the control is added to the userform) will show, and the user can do whatever he/she wants to do. After the userform is closed, this control will be add to the document. Right now I am having some problems with making the ActiveX Control's property persistent. My ActiveX Control has a Get/Set property called "Property1" (type BSTR), and I have a global variable called "Var1" (type CString). In the "GetProperty1" method, I am using the following code: return Var1.AllocSysString(); Now I am trying to drawing the Var1 value in the ActiveX Control's ondraw() method using pdc->TextOut(). I have two questions about this: 1> If I declare my global variable "Var1" as a control wide gloable variable (in control class), I couldn't get the value of this variable anymore after I close the userform in MS Word, which has this ActiveX Control on it. 2> If I declare this variable as a part of "Globals" (in control.cpp), I still can get the value of this ActiveX Control even after I close the userform in MS Word. The thing is when I try to add another control on the document, the variable value is still there, it is not reset. It looks like all the controls on the document are sharing the same value, and their properties values are the same. Can someone help me please? Thanks a lot in advance. Re: ActiveX Control Question Ernest Laurentin25-Apr-02 7:13 Ernest Laurentin 25-Apr-02 7:13  If you plan to have this property "Var1" persistent to your control, then declare it (make it member) inside of your object not global. Why did you decide to create that property as global instead of being a member variable?

I cannot draw anything on the Control, which should be added to the document. Re: ActiveX Control Question Ernest Laurentin25-Apr-02 9:19 Ernest Laurentin 25-Apr-02 9:19  Understand now! Is this a big problem for you to "save" the property value before you close the userform and "set it back" when you need to display that form back again? It looks to me that you want a different property (value) for each control that you use but you want only one variable to store it. In that case, one of the best approach is to have that variable as a member of your component (activex or object). Global variable is not *in my opinion* an elegant option. Good luck! "Dirty hands lead to important discovery..." - Thomas Edison Re: ActiveX Control Question Shayna25-Apr-02 9:24 Shayna 25-Apr-02 9:24  Acturally this Property1 is like a current time property. When a user click on a macro in MS Word, the program gets the current time and I would like to keep this time value with the current control. Then 5 minutes later, this user click on this macro again, it will add another control on the document, but the time value should be different. When I set the Var1 variable as a member variable, the value cannot keep as long as I close the user form. Any ideas? Question for MC++ Forum!

Is there any reason why? Thanks Al Re: Question for MC++ Forum!

Thanks for ur help, Atilla Selem listening to you... Re: help me to load images in a Database and to retrieve them Albert Pascual25-Apr-02 6:17 Albert Pascual 25-Apr-02 6:17  The easiest way is to send the jpg file from the client every times that sends a message to the server. If the bandwith is not a problem! So you don't have to keep a DB in the server side. That's just an idea of course! Cheers Al Re: help me to load images in a Database and to retrieve them Atilla Selem25-Apr-02 6:31 Atilla Selem 25-Apr-02 6:31  how will i do that? using serialization? but think that you should keep all the user pictures as a server since u should succeed to send any one of the user's pic to others who request. or by somehow if u don't want to take responsibility of that you have to contact users to users and make them send pictures to eachother. But they should not be aware of that. i am at that corner of my App and i really think the easiest and efficient way to code. Bandwidth is not problem. But keeping things working is much diffucult. Thanks for all Atilla Selem willing to learn and teach Re: help me to load images in a Database and to retrieve them Albert Pascual25-Apr-02 6:49 Albert Pascual 25-Apr-02 6:49  I don't know your application so I just may be talking bollocks! However if your app is: Server listens in a socket, clients send messages to that socket, server distributes message to all the connected clients. Then when the client application starts, opens a photo.jpg and attaches that file at ever single message going to the server, the server doesn't need to change as it distributes the message and picture together to all connected sockets (clients) If you don't want the user to have to worry about the photo.jpg, in the server you could add all the pictures with username.jpg, when a username connects without a pictures, just push it to that user! Good way to distribute new pictures! Well, that's my idea, however I don't know how did you designed the APP, maybe I am far off your design and to do that will take major changes in the code. Therefor, please ignore this message Hope this helps Al Re: help me to load images in a Database and to retrieve them Carlos Antollini25-Apr-02 6:43 Carlos Antollini 25-Apr-02 6:43  Atilla: Use this Use the functions CADORecordset::GetChunk and CADORecordset::SetChunk Best Regards Carlos Antollini.

In SQL these are know as varBinary, in Access it is of the Type OLE. From an ADO point of view, you would use the AppendChunk and GetChunck calls (I think) to pull and put data in.

Re: Directory Mike Nordell25-Apr-02 9:17 Mike Nordell 25-Apr-02 9:17  No. You have to get the HMODULE/HINSTANCE of the module (check the virtual memory API) and then qury that one, so it's two API functions to call. If you however do implement it in a function, it can become just one function to call. Re: Directory 25-Apr-02 17:33 25-Apr-02 17:33  Thanks for the hint. By any chance, do you know what the calls are exactly? How do I get the HModule etc? THanks.
