Programmatically copying a folder in MFC

Hi, I need to know how to copy a folder and all the contents within to another location set by the user. Because the folders content is read only, I want to be able to make ReadOnly(FALSE);

Is this possible, please help!

Thanks in advance
Ashman

SHFileOperation will help out, its very good api to work around with files and folder.

I searched for SHFileOperation() API calls and I don't understand how to implement it in my program.

Do you have/know of an example that I can use. What I want to do is very basic; transfer 2 folders with all their files intact from location:

D:\Programming\NeriedPOS\nbsSetup\nPOS & D:\Programming\NeriedPOS\nbsSetup\nManager

to C:\Program Files\nPOS with ReadOnly(FALSE)

Would you kindly be able to show me how to do that using SHFileOperation() or any other API?

Please help...its kinda urgent considering I have almost run out of hair to pull Smile | :)

Thanks
Ashman

This

SHFILEOPSTRUCT shfo = {0};
shfo.wFunc = FO_COPY;
shfo.pFrom = "D:\\Programming\\NeriedPOS\\nbsSetup\\nPOS\\*.*\0";
shfo.pTo   = "C:\\Program Files\\nPOS\0";
SHFileOperation(&shfo);

should get you started.

Hello ,

Is there any SDK to implement the AUto-Upgrade feature .I am writing a application in vc++ .Is there anything ,that i can use some SDKs that can be used to check for upgrades for my application from a URL /server ?

Cause is my effort;
Effect is God's effort

What I did, which was kind of slow maybe to create an autoupdater was to get my program to connect to the server, navigate to updates folder and open a file which was similar to an ini file. Get the current version of the program the user is running, set a variable for each new version like; Version 1.10a = 1 and Version 1.10b = 2 etc.

On the server say the new version is Version 1.10c which = 3, try like: Note this is using CIniEx as an example...

<br />
CString strVersion;<br />
ini.Open("Version.ini");<br />
strVersion=ini.GetValue("Program","Version");<br />
<br />
if(strVersion == "3") //Just an example, or just get the string value from a file on the webserver<br />
{<br />
//You have the current version<br />
}<br />
else {<br />
//Open another file to get the location of the new updated program and then download it and execute it<br />
}<br />
<br />

Just a suggestion....bit hard to explain considering Im a complete knob. For some reason things just work themselves out for me programmatically Confused | :confused:

. Hope that helped. Unsure | :~

The Depends utility that ships with Visual Studio is good for this.

However, unless the functions are decorated C++ ones, Depends will not be able to provide much by way of parameter information;
Sometimes you can get a very small hint, if the exported name has @nn after it, since that tells you the size of all the parameters, but of course, you still need to be able to read the disassembly to work out a bit more by way of context Wink | ;)

To handle a change in the combobox, provide a handler for the CBN_SELCHANGE message. To get the value in the edit portion of the combobox, use GetWindowText().

How are you communicating with the database (e.g., directly, ODBC, DAO)?

For the grid go to http://www.codeproject.com/database/msdatagrid.asp[^]. While if you want to read something about databases check this link here in codeproject http://www.codeproject.com/database/#ODBC[^].

Sorry, LamLie but these are not questions that can be answered with short and simple sentences. Not to instult you or anything but if you are new to database programming then you must read a few articles on how to move from one record to another and how to store them. Personally, I prefer ADO because that's the one that I learned how to use. Codeproject has a section and databases and you will find a lot of helpful articles in there.

File sharing problem

Good day,

I'm creating a program that compiles visual C++ program so that i dont
have to switch and make the project active, since i have a lot of projects
on my workspace.I perform the compilation by creating a process so that the
main process could not be affected by its slow compiling..

UINT CompileReleaseMode(LPVOID pParam)
{
::WaitForSingleObject(g_eventStartRelease, INFINITE);
....
....
if(!CreateProcess(NULL,"msdev e:\\app.dsw /MAKE \"app - Win32 Debug" /REBUILD /OUT
c:\\Status.log", NULL, FALSE......);
WaitForSingleObject( pirelease1.hProcess, INFINITE );
}

In my dialog i have a listbox where i could put the filtered compilation message based from the log file(status.log). So i created another thread to read the file(running parallel with the first process) or have it back-up so that i could read the current change of file and reflect to the listbox the filtered message.

My problem now is that when the thread the reads the log file(it generates an error).
How can i access the content of the file or get the last line that have been updated.
(we can see that file has been updated as compilation process.. by executing
type status.log on command prompt.

Thanks a lot and have nice day Smile | :)

Instead of using msdev.exe and a log file, use cl.exe instead. It sends everything to stdout which can be captured and displayed accordingly. This is what msdev.exe is doing. The contents of the Output window is actually what cl.exe would otherwise send to stdout. Check out these two articles:

Hi All,

May be i have created a my thread in Wrong Forum. Sorry about that.

I am writing a event listen for Internet Explorer, For that i am trying to get the connection point interface
for IDocHostUIHandler .interface.

 static const GUID IID_UIHANDLER =<br />
		{0xBD3F23C0,0xD43E,0x11CF,{0x89,0x3B,0x00,0xAA,0x00,0xBD,0xCE,0x1A} };<br />
		<br />
bool bAdvise = FALSE;<br />
DWORD someCookie;<br />
bAdvised = AfxConnectionAdvise(m_pValidPtr,IID_UIHANDLER,m_pValidPtr->GetInterface(&IID_IUnknown),TRUE, &someCookie);<br />

The function returns false. Can anybody explain me why function returns false?
Thanks in Advance

You need to get the pointer to dispatch id IDispatch not IUnknown

Hi Prakash,

Thanks for quick reply,I forget to mention that parameter "m_pValidPtr" is a
pointer to the class derived from CCmdTarget..
I tried to change from IIUnkown to IDispatch.
But its still returning false. Could you please explain why ??

Again thanks in advance
