Hi all
I've built a sample code named "enrollCustomCMC" in Windows SDK at "Microsoft SDKs\Windows\v6.1\Samples\Security\X509 Certificate Enrollment\VC" directory, but when the ".exe" file is built and I use it with the "Command Prompt", I see error in first "CoCreateInstance" function as "REGDB_E_CLASSNOTREG" that means: "Class not registered"!
I couldn't find the reason even with debugging!
The code is written using COM interface, here's the code:
#include <stdio.h>
#include <certenroll.h>
#include <certsrv.h>
#include <certcli.h>
#include <wincrypt.h>
#include "enrollCommon.h"
void Usage()
{
wprintf(L"Usage:\n");
wprintf(L"enrollCustomCMC <name> <value> <dns> <eku> \n");
wprintf(L"Example: enrollCustomCMC Name Value ");
wprintf(L"www.adatum.com 1.3.6.1.5.5.7.3.1\n");
}

What's the problem?
And does this code need to a CA(certification Authority) to send request for?
Is it possible to run this code on XP client than Vista?
I asked this question on "Windows SDK" forum, but didn't get any respose!!
Please help me...
THX.

What are the setup instructions for the sample?
Are the COM classes registered using regsvr32.exe?
|
|
|
|

The documentation clearly states that these API's are available starting with Windows Vista. So no XP

I have no clue how to pass data to my threaded function.
_beginthread(MyThreadFunction, 0, NULL);
Tried to pass a value like in regular C++ functions.
_beginthread(MyThreadFunction(MyData), 0, NULL);
Kept getting compile errors! 
|
|
|
|
|
Arguments to threads are usually passed as void pointers (void*).
So you need to pass in what ever is needed by typecasting it to a void*.
So if you want to pass an integer -
int i = 10;
_beginthread(MyThreadFunction, 0, (void*)&i);
|
|
|
|
|
How would the thread function declaration look like?
|
|
|
|
|
|
_beginthread(DownloadThread, 0, (void*) NewDownload);
void DownloadThread(void *D)
{
CDownload *Download = (CDownload*)D;
}
Compiles, but once the _beginthread is called the program crashes!

How is NewDownload declared?
|
|
|
|
|
1) Window that accepts URL
2) Pressing OK
3) Break down URL store it in CDownload *NewDownload;
4) After NewDownload has been filled out.
5) I pass NewDownload to download function to test if it the download function works
6) Add NewDownload to Linked List
Production code, user will be able to pause/resume called the download thread
|
|
|
|
|
Declaration, not implementation or use. In other words, is NewDownload a CDownload object?

"Fireproof doesn't mean the fire will never come. It means when the fire comes that you will be able to withstand it." - Michael Simmons

|
|
|
|
|
|
It seems passing Class Object part of a Linked List doesn't not work in this traditional manner!
|
|
|
|
|
Try something like this -
CDownload* NewDownload = new CDownload;
_beginthread(MyThreadFunction, 0, (void*)NewDownload);
|
|
|
|
|
How would the MyThreadFunction declaration look like?
void MyThreadFuction (void* Download)
{
char *HostName = new char[wcslen(Download->HostName)+1];
}
error C2227: left of '->HostName' must point to class/struct/union/generic type
|
|
|
|
|
void MyThreadFuction (void* Download)
{
CDownload* NewDownload = (CDownload*)Download;
char *HostName = new char[wcslen(NewDownload->HostName)+1];
}
|

Thank You for your patience.
Actually I had done that same workaround fix, but since of my inexperience I thought I was doing it wrong.
As it appears I found another reason causing the disruption which has caused all this fuss.
Since I'm using long long, doing a percentage calculation. However because of 0 being part of my calculation. It crashes! Bringing up lldiv.asm to Line 121 due to the 0 value. Anyway I will try understand went wrong later. Thanks again for your help Nameless MVP!

I briefly talk about this here.

I remember reading that - a great piece of code (not that you need me to tell you)
I'm sure someone was asking about printer notifications recently here on CP as well, so your article was timely.

<pre>_beginthread(MyThreadFunction, 0, NULL);
Tried to pass a value like in regular C++ functions.
_beginthread(MyThreadFunction(MyData), 0, NULL);</pre>
look at how you call _beginthread and combine what the other people have already posted. You have the idea, but just look at how _beginthread is defined.

Here's a nice writeup[^] on the subject. He emphasises on MFC, but the idea is the same.
A book on threading would be of immense help to you.

So in a normal C++ environment you can use fstream!
CFile in MFC applications, does anyone know of other file writing functions that don't involve MFC.
While also restricting output with number of bytes to write?

How about WriteFile() and fprintf()?

You could start here[^] and work your way up. The basic IO functions require you to do all the work, in terms of formatting your data.
It's time for a new signature.

I have a lot of legacy code using fprintf(stderr, .....); I also have monitoring pane which is a CEdit control. How can I redirect stderr to output into the CEdit control?
I have a look around but most of the answers involve the creation of a new process. Is any simpler way of doing it? Effectively what I 'd like to do is something like
start redirection of stderr to myEditControl;
fprintf(stder, ....);
finish redirection of stderr
Thanks
