looking at the MSDN[^], they say that :

"To resolve this error, provide a definition for symbol or remove the code that references it"

have you checked this ?

hey you...

not only you don't provide enough informations so that we can plainly understand where you problem comes from, but now you're hurting me because i don't help you enough ?

come on !!! who are you to tell me what to do ? do you pay me to help you ? do anyone here give me money to give help on CP ? are you here for long enough to tell me the do and don't of codeproject ?

now, i tell you one last thing. i'm TRYING to help you. if you don't explain WHERE - in the code - you're having the problem (giving a code sample would be great), don't expect anybody to do a miracle only because you're too lazy to find an answer by yourself. i'm ok to help you, but provide valuable infos.

creating setup for application

Tara1419-Jul-06 20:19

19-Jul-06 20:19

Hello,

I have developed an application in vc++, mfc using Access as the database connected with DAO.

I have to create a installable version for the application. The setup should have a product key, should create a desktop shortcut and a system tray icon.

I have InstallShield for vc++6. Please can you guide me on how to go about doing this.

In my program, at present I have specified the path where the Access file is. ie. I have given the path as
CString strPath ="C:\\store\\store.mdb"
But when I create the setup file, when the user installes the program, I want the path in which the user has installed the program to be taken as the path for the database.

Does the programming for the desktop icon, system tray icon, and path of database have to be done in my main program itself, or when creating the setup file.

Kindly advise.

Thanks,
Tara

Thanks.

Please may I konw where do I do the codeing for creating a desktop icon, and the system tray icon? And also the path of the database? Suppose I the set the program to find the path of the exe file and set the path to that would that be a better solution?

I think you need to set the path to the database and to create all that shortcuts from the setup application. So you need to modify the script from the InstallShield. You could try a newer version available on http://www.macrovision.com/downloads/index.shtml[^] for evaluation.

Hello,

I took a look at Inno setup. I have never created a setup file before, so I do not know which one is better. I looks like it is easy to use though, compared to InstallShield.

So the Inno setup will take care of creating the desktop icon and the tray icon. But I still am not sure how to set the path for the database. I mentioned earlier that I could code my program to look in the same folder where the exe file is located and set it as the path. Is that the right solution?

Any help will be highly appriciated.

Thanks,

VSS automation problem

stanlymt19-Jul-06 19:59

I'm using VSS interface in my program.
I'm getting the latest version of the file by using Get function in IVSSItemPtr.

IVSSItemPtr vssi;
COleVariant varBuf(strProjectFolder);
vssi = m_vssdb->GetVSSItem( varBuf.bstrVal,0);
vssi->Get( NULL,VSSFLAG_USERRONO | VSSFLAG_RECURSYES | VSSFLAG_FORCEDIRYES | VSSFLAG_GETYES );

The above code works perfectly for me. It gets the latest version. But I'm suffering from biggest disadvantage. Once this function is called it disables my main application. No messages are handled by main window, when the Get function is called. Once that function execution is finished then only Window accepts messages. Till then all the messages are blocked. Even all the threads are suspended. For large folders when we use Get function, it's takes very long time and it's quite annoying that Window gets disabled and all background threads are suspended. Is there any way to overcome it? I wanted to monitor the status of the Get function. Is there any way to run background thread to monitor it? Can we enable the Window to accept messages.

Thanks,
Stanly

Why not do it the other way around, and spin off a new thread to perform the get?
Of course, you'll need to coinit your new thread and marshall your interface into the new thread, but that isn't exactly rocket science. Your 'get' thread can post a message when it's complete.

Unfortunately, there don't appear to be any useful events that fire during the get, so you can't "monitor" as such. An alternative would be to handle the recursion yourself in the thread, and have the thread post messages to your UI thread or a window.

The application 'hangs' for a simple reason; the UI thread it isn't pumping messages, because the call hasn't completed yet. When you say the threads are suspended, I'm guessing that none of them have their own message loops.

Thanks a lot for responding. I tried using thread to perform 'get'. In this case also, once the 'get' function is called application is not responding to any messages even the message loop of each thread. The 'get' completely blocks other messages. I tried using recursion mechanism to 'get' file. There is a major drawback for this method. The performance is affected to a large extent. It's take very long time to get a big folder because it has to recurse to each folders and subfolders. Thats why I thought of shifting to single call mechanism to 'get' whole folder. Can you please help me with this problem?

Thanks,
Stanly

It is a lot of work (in terms of CPU time) to get a large folder and any subfolders. If you do it using the SourceSafe UI, time it and see how long it takes - and then compare that with your single get, and if possible, your recursive version.

Doing the automation work can be a bit of a pain, but if your code is reasonable, it shouldn't be that much worse than using the SS UI.

What exactly are your other threads doing, and have you adjusted the priority of them? It sounds like you're just CPU starved, and while SS uses a lot, you should be able to do other things at the same time - I have a snapshot utility that replicates a given SS db to a new SS db (eliminating any history) and I can run other stuff along side it, although I have a P4 2.8GHz cpu ...

I found that the CPU is much lesser(30%) than total CPU available. The single get is much faster than recursive version and also it's faster than SS UI.
It's better than SS UI.
The VSS database is located in remote machine. Is it because of reading from remote machine makes the application to freeze? One thread is to monitor the content of one folder. The control is never reaching this thread, once the 'get' function is called. I tried using timers also, timer event is also not happening. Thanks a lot for your help.

How do you know that the thread is not running? Does it have it's own windows and message loop, or are you outputting to a debug window (TRACE/ATLTRACE/OutputDebugWindow)?

The single get will be faster, but then you have to do your own monitoring of progress, which means looking for file change notifications etc. I suggested the recursive version because you said you wanted to have progress notifications, and this would be one way. I'm guessing that the SS UI does it this way, since there aren't events that get fired (at least, not that we get told about!).

It might be the STA that's contributing to the lockups. You could try using CoInitializeEx to get an MTA instead (in both the main thread and the get thread), and see if that helps at all.

When you say timers, do you mean SetTimer(), which will only cause WM_TIMER to be pulled out of the queue, which, as you're not pumping msgs, won't be happening....

I know the control is coming to that thread because I've put some debug logs which was not printing. I think I'll go for recursive version.
Thanks a lot for your help.

<br />
	DWORD m_dwSize=WriteToFile.GetLength();<br />
	BOOL bResult=WriteFile(hFile,(LPCTSTR)WriteToFile,m_dwSize,&dwRead,NULL);<br />
	CloseHandle(hFile);<br />
<br />
CString strRead="";<br />
DWORD dwReads=0;<br />
