why do have to restart to get excel/ word application. every time
-
Hi COM Expert. I have a ms word automation, dos-based, application that support MFC. The programming is running perfectly right now. and a few minues later i got " Couldn't create MS Word Application Object". at
app.CreateDispatch("Word.Application");But I restart the computer and the program works again. why is that? is it because of OLE did not get initialized? why i have to restart the computer in order to work fine. what is wrong with that? here are my code// PrintMSWord.cpp : Defines the entry point for the console application. // #include "stdafx.h" #include "PrintMSWord.h" #include // OLE2 Definitions #include #include "msword9.h" #ifdef _DEBUG #define new DEBUG_NEW #undef THIS_FILE static char THIS_FILE[] = __FILE__; #endif ///////////////////////////////////////////////////////////////////////////// // The one and only application object CWinApp theApp; using namespace std; int _tmain(int argc, TCHAR* argv[], TCHAR* envp[]) { int nRetCode = 0; // initialize MFC and print and error on failure if (!AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0)) { // TODO: change error code to suit your needs cerr << _T("Fatal Error: MFC initialization failed") << endl; nRetCode = 1; } else { // TODO: code your application's behavior here. // getting the file name CString fileName; for (int i = 1; i < argc; i++) { fileName += argv[i]; fileName += " "; } //fileName = "e:\\apqad.doc"; cout<<"Opening "<<(const char*)fileName<<" ..."< -

Otherwise, the reference stays alive despite app.quit. Try to find a way to nullify or destroy all your reference objects rather than just letting them go out of scope. I see that you call CoUninitialize() and ReleaseDispatch(), but like I said I don't know enough about MFC to know how these work. Maybe try testing your objects before you return to see if they are fully destroyed. Hope I helped.

what do you mean by saying
Try to find a way to nullify or destroy all your reference objects rather than just letting them go out of scopeI'm using network though. this program has been 4 days.. it works fine now and later it is not.. i have no clue at all coz this is my very first COM or Automation application. I tried so hard to understand what is really going on within my application that sometimes works and mostly not. I couldn't find any book that's talk about why i can't get my word.application. I though it is because I couldn't initialize OLE libs. Anybody Anyone can tell me what is wrong with my code? what is causing my application not to app.createdispatch("Word.Applicaiton"); -

Try to set your Word.Application object to null or something of that sort. I wish I could help more, but I don't know MFC well enough. Hopefully someone on CP can be more useful.

Thanks for your explaination. You are helping me and I don't know VB either but I think as long as the classes or functions is win32 API, both VB and C++ programmers can use in the same way, ofcourse the syntax will be different. Anyway..Let's talk about my problem. Let me tell you one thing I just found out. As I told you, I'm using Network. I have C:\,J:\,I:\,H:\,G:\...etc. C:\ and G:\ drives is only I can access. It is private. but J:\, I:\ and H:\ are public. All the users can access to those drives. J:\ is a common one. All the users are on J:\ all the time. My program give me a message "Couldn't create MS Word Application Object ",
_Application app if(!app.CreateDispatch("Word.Application")) { AfxMessageBox("Couldn't create MS Word Application Object "); return 1; }but not from other running from C:\ and G:\. So can you give me any suggestion what do I need to change or do inorder to let my program run correctly on J:\?oh.. it is only works on my machine.. i mean even I copy my program and paste other users' c:\(machines). still it doesn't work.. the same message is giving me... -

If not, then it is a compatability issue. If you're using .NET then it could be something with the security permisions. Set everything to full trust and see if that works. Other than that, I don't know what could be causing it. Sorry.
