Microsoft used to have Viewer applications for all these file types. Have a look on the office web-site. I know I downloaded a Powerpoint viewer a little while back.

Alternativly, have you looked at http://www.openoffice.org/[^]

fro win98, you need to use the unicows libraries.

see this :

CRectTracker inside CScrollView

Anonymous22-Dec-02 18:29

22-Dec-02 18:29

I wrote a program that one could choose items from a toolbar and put them on the document by clicking left
button of mouse on the view. I considered a CRectTracker variable for each symbol and in the OnDraw function I
draw each symbol's tracker's rectangle.And for selecting each symbol which is shown on the page I check if the
position of left click of mouse is in the tracker of any of the symbols or not.
At the beginning I used CView class but now I want to use CScrollView in order that my program could support scrolling.I changed the base class of my view class to CScrollView and write some lines in its OnInitialUpdate in order to set the size of scrolling.Even I changed coordinates with CDC::DPtoLP function.
Now I scroll my program but when I put an item on the page and scroll the page , in some places that my item doesn't
exist , it seems that its tracker exists .

In the dialog editor, press Ctrl+D to set the tab order. Each control will have a number by it, just click the controls to set their new order. (ie, the first thing you click will be #1, the next thing #2, and so on)

hi,

I'm developing ATL ActiveX EXE server that runs as a Window services using ATL wizard.
This server contains one ATL object (CTest).
How I can set the server so that when it started (via Window Services Applet), the server will :

1) initiate/create CTest.
2) Call method/function in this ATL object (CallMe).
3) destroy CTest when server stopped.

Thanx in advance.

Regards.

There are numerous installer products, some free some not. InnoSetup, SuperPiMP, InstallShield, etc. You'll have to try them out and see which one you like best.
As for dependencies, run the Dependency Viewer found in the VC6->Tools program group.

Delete your .CLW file and when you open the Wizard, it will ask you if you want to rebuild it from your source files.

I want to get C++ to communicate with an http server across the internet, not a LAN, the internet. What do I need to learn to do that and are there any books that use C++ not C# that concern this issue?

Winsock End-of-Message Response :: Winsock

Hi.

What is the best solution to knowing when a server or client has sent the final piece of data across a socket?

For example, let say a client sends 100k of data to a server running OVERLAPPED I/O. The I/O model updates the server and tells it there is 50k data ready for to be received. The server calls WSARecv(). Meanwhile the server has not idea the true size of the data. It just knows there is 50k worth of the data. Now OVERLAPPED I/O updates the server the second time with 50k data, which is the last piece of data.

Based on the example scenario, how does the server know when to stop calling WSARecv() because it has processed all data? This is a general question and does not pertain to data. Is it true that web servers sends the final piece of data with something ike this at the end?

You need to build it into the protocol the two apps are using to communicate e.g. the first 4 bytes sent are not data but the #bytes to follow.

kuphryn wrote:

Again, it depends on the particular protocol being used. For HTTP, I just wait until the server closes the connection which gives me an error when I call WSARecv(). A bit hacky but since HTTP is stateless, I can't think of a reason why the server would ever want to keep the connection open and so this should be OK.

CPropertyPage Default Button

Hi.
I've created a dialog with a CPropertySheet on it and a few CPropertyPages, this is not a wizard. For each of these pages, I would like to have a default button. Setting that attribute doesn't appear to work. I tried overriding OnOK of the dialog, checking the active page, and then calling the default button, but the message isn't sent when I press return. Any suggestions on what I should try?

I've searched here and several other places but couldn't find an answer, I'm sorry if I've overlooked it.

Thanks
