Re: How to create a timer event which can run continuosly. Alex_Y25-Jul-05 3:29 Alex_Y 25-Jul-05 3:29  I don't know other way than: UINT_PTR SetTimer( HWND hWnd, UINT_PTR nIDEvent, UINT uElapse, TIMERPROC timerFunc ); static LRESULT CALLBACK WindowProc( HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam ) { switch(uMsg) { case WM_CREATE: { SetTimer( hWnd, 1, 1000, NULL) // 1000 - 1sec } break; case WM_TIMER: // do something break; case WM_QUIT: KillTimer(1); break; } } } Opening a document (MDI) vasanth100425-Jul-05 3:08 vasanth1004 25-Jul-05 3:08  How do I open a document from within my CDocument derived class? I tried CMyDoc::OnOpenDocument(LPCTSTR pathname), but that doesn't work. Re: Opening a document (MDI) Alex_Y25-Jul-05 3:21 Alex_Y 25-Jul-05 3:21  You not opening document. Ususaly when you click on menu File New or Open function OnNewDocument or OnOpenDocument are called automaticaly. Document template wants to control all creation and deletion of documents. You can treak it if you look in CDocumentTemplate. Can we launch/open a Web page? ATC25-Jul-05 2:53 ATC 25-Jul-05 2:53  I have a VC++ application that link/update/retrieve data of a MS access mdb file on the web. However, I do not know how to launch/open a web page through this application Anyone knows how to do it? If so, can we are able to close it after launching? *) The reason I ask for help, because I need to update data to that MS access mdb file without requiring the user to launch the web page himself! Thanks for any help Re: Can we launch/open a Web page?

ATC25-Jul-05 15:50 ATC 25-Jul-05 15:50  Hi David, I only use ShellExecute(...) to launch a local application but not in the web, I did verify to use ShellExecute(...) to launch a web page, but none available! Do you know any link/guide? To link to the web site I used pConnect->OpenFile (fileSem, GENERIC_READ, FTP_TRANSFER_TYPE_BINARY,1); or similiar to transfer, write or read a datababse ... not to launch a web page! Might be you kind of provide me a simple command to launch a Web page? Thanks Re: Can we launch/open a Web page?

Is the mdb on a remote server which has a web interface? Are you trying to access the web interface from a client application?

Thanks for trying to help MS-Word automation and Virtual memory Imtiaz Murtaza25-Jul-05 2:41 Imtiaz Murtaza 25-Jul-05 2:41  Dear fellow developers We’ve developed a windows based desktop application. The application is built using Visual C++ 6.0 and MFC. In our application we are automating MS-Word. The user clicks on a button and as such MS-Word application gets opened which hosts the desired document. When the word document gets opened, the user starts typing on the word document as usual. Once the user finished with the typing process he/she saves the document and then closes the document and afterwards the word application. The resultant software is working fine on our machines. But when we released the software to our clients, MS Word starts creating the trouble. Here is the description of the problem: The user launches MS word document from our application and starts typing in it. Now during typing, the MS-Word application gets crashed. This behavior is produced unexpectedly and is not reproducible. It is only happening in the MS-Word instance which is automated by our application and not by the externally launched MS Word instance. We’ve made some research on the machines where this problem is occurring. And we’ve noticed that those machines are short of Virtual memory. During the course of time when MS-Word window is opened, the application (or our automation client) only calls the word Save function and also calls the function which returns the current selected text. We only use MS-Word 2000. Please advice us how can we get rid of this issue. Please also suggest us the ways to trace this error.

I want that when the second button is pressed the program should exit that while loop......... How can i do that plz be elaborative as i m a beginner in VC the more u give the most u receive Re: exiting the infinite while loop Trollslayer25-Jul-05 1:13 Trollslayer 25-Jul-05 1:13  This looks like homework. Create an event handler for the first button and in the event handler break out if the second button is pressed. You should be able to work the rest out yourself otherwise you will not learn.

Inside the loop pump the message queue. In the command handler for the other button, set the flag. There is no need to create threads to do this. Tim Smith I'm going to patent thought. I have yet to see any prior art.

TOXCCT >>> GEII power [toxcct][VisualCalc] Re: exiting the infinite while loop Tim Smith26-Jul-05 3:46 Tim Smith 26-Jul-05 3:46  Thus the requirement to pump the message queue. How do you think programs did it prior to having threading? Tim Smith I'm going to patent thought. I have yet to see any prior art.

Re: Stack overflow khan++25-Jul-05 0:54 khan++ 25-Jul-05 0:54  I think it is because it is a global object, and when you call exit(), it calls the global objects's destructor, which causes an endless loop. Make it a local object, and it runs with no problems. Remove the exit(1) call from the objects's destructor. I am still confused. this is this.

Yeah, I guess you're right!
