I cut & pasted your code into VC and it compiled fine.

Hi
I have a generic class (KodakCard) which has an ActiveX control in it. The ActiveX control can fire events, but i don't want to receive them in any of my view classes but instead within the KodakCard class. This would be good encapsulation. Yet because KodakCard is a non-MFC class it doesn't seem to be receiving events (nor any other of my view classes presumably because they're not hooked up to the control).
So how do i do it? I'd prefer to keep it all MFC, without any ATL stuff, but whatever is easiest.... ...I've tried creating a new class derived form CmdTarget (CKodakEventSink) and editing the *.odl file and adding the activex control's guid to it then creating an instance of CKodakEventSink in KodakCard but I can't get it to work because i don't understand *why* I'm doing it (even MSDN can't help sometimes  ...
If someone could explain the logic involved or point me to a web page/book that explains this process that would be great...
Thanks
Brendan

Check my website www.braem17.yucom.be for an example on how you can receive events from an ATL control. You can find the page on http://www.braem17.yucom.be/FileMonitorSample.htm. It describes how can use the FileMonitor control in a MFC project.
hope this helps,
Franky.

Hi,
You need to write a sink in ur class which will hook up with the activex control. The events fired by activex control are just callback functions of a class, the activex control defines a class for the client to implement, once you link ur class to the activex control using the Advise method the events that are fired by the control actually executes the functions in your class that u have linked. For more information please refer Connection Points in MSDN COM Section. Or Just search for Connection Point.

Good evening,
Trying to develop a solution the right way. I'm trying to keep this whole thing as modular as possible, so that if one application(except for the manager) goes down, no other application, including the manager is affected.
I have one application(process) that manages many resources, it is important that these resources are available 24/7. Different applications( about 20 different ones, each of which at times are taken down for modification/upgrade ) will interface with the managing application for use of the resources. The manager will tell the application that is using the resource that a specific event occured and the application will respond with next action(state machine). The manager will take the action on the resource, and send the next event to the application using the resource... until the application is done with the resource... when done with resource the manager adds it to the pool for availability.
I am presently using MSMQ for the communication. I basically send a const recognized by all concerned in the subject line, and if any data is required, I put it in the body in comma delimited format.
It seems I'm working really hard to keep this thing together. Additionally, these events/responses must be quick... I can get up to 150 a second.
How would you do it?
Thanks!
Scott!

I wanted to delete several classes from my project. Following procedure given about 1000 posts ago I removed the .cpp and .h files for the undesired classes from my project folder. I then deleted the .clw file, reopened my workspace and hit Ctrl+w. The Class Wizard came-up and said I had no .clw and would I like one? I said yes and .clw was rebuilt. I examined the .clw and the unwanted classes are indeed gone.
Problem is this: the deleted classes still show-up in the Class View window, and the file names of the removed files persist in the File View window. How can I cause my workspace view windows to show the updated project configuration?
I am running VS5-SP1, in the process of d'loading SP3.
Alternatively, what I am trying to do is set-up a project workspace that is hooked-up to MFC and wizards, but I want to avoid (for the time being) some of the files that AppWiz generates for me so that I can build from scratch and learn the details. I want to keep only the app class and the mainframe class.
I am a beginner at MFC and VC++, but I have solid experience in C.

Why are you d/l SP3 instead of 4 ? Are there issues I haven't heard about ?
As to your files, if they've been deleted from the folder, and also removed from the project in file view, I'd be surprised to imagine where visual c is finding out about them. There are a number of other projectname.ext files, you *could* back them all up and try deleting other files as well as the .clw and figure out where it's being stored there.

Close the workspace, delete the project.ncb file, then reopen the workspace.

Okay, the unwanted classes are gone, now.
Just a beginner's mistake. Turns-out that "Delete" does not show-up on the shortcut menu (right-mouse-click menu) when in File View, so I deceived myself into thinking that there was no delete option. The "Delete" option is in the edit menu of the mainframe, as Christan pointed-out.
Rereading the Environment User's Guide.

You can also just hit the delete key.

Yeah - it's easy. You reset all your variables ( score, player data, etc. ) and restart your main loop. The best way is to externalise your setup code into a function that gets called on startup and again when you want to restart the game.

I cant figure out, how to make so when i push a butten my icon or bitmap get invisibel... I know how to do it to a butten, but it dosnt work with a bitmap or icon...
I also need a litle help to make a background to my program, i would like to place a bitmap behinde all of my buttens, but it allways place over the buttens not behind.. need help 
Thanks

To make icons/bitmaps invisible, you need to assign them an id other than IDC_STATIC in the resource editor. Then in your message handler for the button (Assuming IDC_ICON_IDENTIFIER is the identifier you gave the icon/image):
GetDlgItem(IDC_ICON_IDENTIFIER)->ShowWindow (SW_HIDE);
or
GetDlgItem(IDC_ICON_IDENTIFIER)->ShowWindow (SW_SHOW);
As for placing bitmaps behind buttons, I've never done this because it sounds ugly to me  . But something like the following should do it:
GetDlgItem(IDC_BUTTON)->SetWindowPos(GetDlgItem(IDC_BITMAP), 0,0,0,0,SWP_NOMOVE|SWP_NOSIZE);

I'm going out on a limb here, but I think you've misunderstood the second part of the question. I think he wants a bitmap background on his dialog.
If so, you do that in OnPaint, and you create the CBitmap from the resource, select it into a DC and Blt it over the dialog yourself.

Hi:
Could you please help me in how to store data from MFC application to Execel file?
meaning that I have data in integer and each one has a lable, how can I save them in to .xls files.
I'll really appriciate your help...
thank-you.
|
|

|

Does it have to be saved directly to an xls file? Things would be much easier for you if you could save it out to a Comma Seperated Values (CSV) file which could be imported into Excel. If it needs to be directly to Excel then check out

Thanks for your help but could you please tell me to import a comma separated data's to Execel, Because I am not familiar with SQL and Excel files...
thank-you

There's no need to use SQL. If you create an ASCII text file like so:
Label1,Value1
Label2,Value2
and save it with a .CSV extension, you can open it up in excel directly (like it was an .XLS file). I'm pretty sure that Excel's installation sets up the CSV file types, but if it doesn't, just click on File...Open. Change the type to Text Files and open up the file.
