(assume your talking about an MFC tree )

when you insert a new node in the tree, you will have an HTREEITEM, and with it, the CString that is the key.

( not tested )
so you use a map like this std::map < CString, HTREEITEM > and insert the info in the map.

and lookup the map with the CString key to find the associated HTREEITEM.

Struct question

Is is possible to have a variable length char in the sturcture based on the value of another struct object.
For instance here is my struct:

struct myMsg{<br />
    BYTE msgNulls[53];<br />
    BYTE STAP[4];<br />
    BYTE BlockLen[4];<br />
    BYTE HDRLen[2];<br />
    BYTE FunctionCode[2];<br />
    BYTE ValField[4];<br />
    BYTE DataLen[4];<br />
    BYTE StatusCode[2];<br />
    BYTE Dest[2];<br />
    char DataField[DataLen];<br />
    BYTE STOP[4];<br />
};<br />

I wnat Datafield to be the length of whatever datalen is. I know that I cannot do it like as shown but is there a way to do it?

Thanks

Make DataField a char * and allocate the memory from the heap as needed. Don't forget to free it when you clean up your structure.

onwards and upwards...

Do you mean that it should be this:

struct myMsg{<br />
BYTE msgNulls[53];<br />
BYTE STAP[4];<br />
BYTE BlockLen[4];<br />
BYTE HDRLen[2];<br />
BYTE FunctionCode[2];<br />
BYTE ValField[4];<br />
BYTE DataLen[4];<br />
BYTE StatusCode[2];<br />
BYTE Dest[2];<br />
char* DataField;<br />
BYTE STOP[4];<br />
};<br />

?? or is there something else...Don't tell me let me figure it out!

It looks like you are trying to extract data from a binary data stream. So the quick answer is no, you can not do that. That stuff about allocating memory and using a pointer in the structure doesn't help you since it would be the pointer in the data stream and not the actual data.

Retrieve a list of files on my ftp-server using MFC

Hi!

I’ve successfully made a connection to my ftp-server and made calls like:
CFtpConnection::PutFile
and so on.

Now I like to retrieve a list of all files in a specified dir and then download them using:
CFtpConnection::GetFile

I’ve searched in classes like CinternetConnection but no success…

Tips?

Write a program that talks to the com port on the remote pc then realys the information to your program via sockets. You may want to use DCOM for this as you can have DCOM execute your application on the remote machine and it will appear that it is running on the local machine.

> Virtual COM mapped to that IP is on mine System say COM8. I know its IP only .

The IP address of the virtual port is not needed as this will require you to write your own virtual com port driver which will be difficult without any documentation.

You need the ip address of the remote system only.

> so how read and write?
Use the serial communications APIs.

Net send is done with sockets. Windows has an alerter service that catches the message and sends it to the console. Here is some info on the Alerter service: "Notifies selected users and computers of administrative alerts. If the service is stopped, programs that use administrative alerts will not receive them. If this service is disabled, any services that explicitly depend on it will fail to start."

How does one use MFC (especially the dialogs) with the Visual Studio .NET 2003 AddIns?

I always get an error message saying that DLLMain has been defined twice. I have changed the Project settings and included the necessary files but still no luck.

CertOpenStore problem

I'm trying to open the system store from IIS web extension and I
get an ACESS_DENIED error. It works when I run extension in "High-Isolation" mode under account belonging to Administrators group (which is not safe at all!!!), but id doesn't work if I run it under local IWAM_ account or specially-created "non-administrator" domain account. Where (and how) adjustments should be done to make it work?

Here is the call I make (C++)
store = CertOpenStore( CERT_STORE_PROV_SYSTEM,
PKCS_7_ASN_ENCODING | X509_ASN_ENCODING,
NULL,
CERT_SYSTEM_STORE_LOCAL_MACHINE,
L"MY"
);

Thanks,
Andrey

try CERT_SYSTEM_STORE_CURRENT_USER instead of
CERT_SYSTEM_STORE_LOCAL_MACHINE.

I have tried both of them - the same problem - this API call returns NULL and "ACCESS_DENIED" error code is returned by GetLastError();

How can I create a application in VC++ 6.0 that is invisible and that does not show up in taskbar.

I created the application, but it only hides after blinking. How can I overcome that. ?

Thanks in advance

It sounds like you are talking about ShowWindow(SW_HIDE).
