I need a MFC app which I can give a directory and it will create a list of all files within that directory and sub directories. From this list it will then check the last time each file was modified. What would be the best way of going about this? I think of several ways of doing it but would like an opinion on what other people think would be the best way forward. Thanks.

FindFirstFile, FindNextFile, should do it quite easily. Just need to look at what you need to pass to it in terms of parameters. Or use CFileFind for straight MFC.

Ok, I couldn't get that from your language.

Now, what exactly is the problem, you are neither able to paste anything nor able to type anything? Is that edit box readonly by any chance?

when I tried CEdit::GetLimitText(), it returned 30,000. This is in contrast with what is described here in remarks http://msdn.microsoft.com/en-us/library/bb761647%28VS.85%29.aspx[^]. I think your problem is when exceeding this 30,000 characters. Try calling CEdit::SetLimitText() with much bigger value and count the number of characters you could paste/type.

A multi-line edit control can only hold 64K characters. Use a richedit control instead.

You mean you want to use your C# code in C++? Why do you want to use C++?

In C++, if you want to use web service from scratch I'm afraid it will not be easy.. you will have to do it manually (HTTP, TCP/IP sockets, XML, SOAP).

Hi,

I want to read a text in an excel file. I am using the folowing code.

HRESULT hr;
CLSID clsid;

hr = CLSIDFromProgID(L"Excel.Application", &clsid);

BOOL bRet = objApp.CreateDispatch(clsid);

objBooks = objApp.GetWorkbooks();

objBooks.Open("C:\\tmp\\1.xls", VOptional, VOptional,VOptional,VOptional,VOptional, VOptional,
VOptional, VOptional, VTrue, VFalse, VOptional, VOptional);

It is working in a test applicaiton. But i am using the same code in my development project, CreateDispatch function gets failed.

Anyone knows the reason?

Thanks,

Use second parameter of CreateDispatch to check what's causing it to fail.

See
COleDispatchDriver::CreateDispatch [^] for it's usage.

Hi,

I am using RasSetCustomAuthData API to set my custom auth info before calling RasDial API.

here is the code piece:

int nError = ::RasSetCustomAuthData(
myphonebook,
myphonebookentry,
(BYTE *)&myCustomAuthData, myCustomAuthData.dwSize );

Here value of myCustomAuthData.dwSize is 2708 . and the size of myCustomAuthData stracture is also 2708. but after calling this function is writting around 5k of data in the .pbk file.

After calling this RasSetCustomAuthdata() api the .pbk file is having entry some thing like this.

64-Bit Printer Driver vs 32-Bit Printer Driver and viceversa

Hello,
I have a problem.
I have installed a printer driver in 64-bit machine (say PC-1)and shared it.
Now if I try to install the printer (which is already shared in PC-1) in a 32-bit machine (say PC-2), I am able to install it.
But actually it shouldn't happen.
And also I have that the reverse case is also working.
Please show me a way restrict this.
Thanks in advance.

Regards,
msr

They are both different machines.
That is why you're able to install it.

I didn't get your point. Can you just explain me.
I agree that both are different machines. But they are of different configurations too.
My requirement is to restrict it.

How do you want to restrict it?
Do you want to administer one machine to not be able to install the driver?
Or do you want to write a software to prevent driver installation?

Why have you shared it if you do not want the other PC to access it?

Just say 'NO' to evaluated arguments for diadic functions! Ash

My requirement is,
A printer shared in a 32-bit machine should be accessible to only 32-bit machines.

And also same case with 64-bit machines.
Now tell me how to restrict it.

I don't think there is any facility for this, as printers are not sensitive to 32/64 bit systems, as long as each platform has the correct printer driver.

Hi,

This is a very strange Confused | :confused:

$Shucks | :-\$ requirement as networks are totally insensitive to the bit width of their hosts (actually they intend to connect any heterogeneous machines using their protocol).

You can probably achieve that by partitioning in two subnetworks each having only access to its peers for resource sharing.
This can be done through your DHCP server if any, or by hand on each machine, or by inserting a router if the network topology fits.

In all cases looks like a bad idea giving more trouble than benefit Smile | :)

cheers,

Implementing CALLBACK in MFC getting error C2440: 'type cast' conversion problem

I need some help with this error.
I cannot compile this AVIcap function call (callback) in CView

capSetCallbackOnFrame(m_hWndCAVIFrame,FrameCallbackProc);

This is the error I am getting

error C2440: 'type cast' : cannot convert from 'long (__stdcall CMyView::*)(struct HWND__ *,struct videohdr_tag *)' to 'void *'
There is no context in which this conversion is possible

The callback is defined (per documentation) :

LRESULT CALLBACK CMyView::FrameCallbackProc(HWND hWnd, LPVIDEOHDR lpVHdr);

And implemented this way:

LRESULT CALLBACK CMyView::FrameCallbackProc(HWND hWnd, LPVIDEOHDR lpVHdr)
{ …...

I understand that the second parameter in capSetCallbackOnFrame should be a pointer to the callback function, however, I do not understand what I need in addition to “CALLBACK”.
I have tried cast to long* (capSetCallbackOnFrame(m_hWndCAVIFrame,(long*)FrameCallbackProc);) but it did not work and I really do not understand why.
Any constructive help is as always appreciated.
Thanks for your time.
Vaclav
