OK 
Please compare also:
Start -> DCOMCNFG -> Componen Services (?) ->
Computer -> Workstation -> ContextMenu ->
Properties(Settings?) -> COM Security & Other pages there.
Try also to unregister
and then to register the server in its actual directory again,
and the CoInitializeEx(..) too virtual void BeHappy() = 0;

This absolutely worked! Someone on the server made some settings on the specific application properties -> identity tab that a specific user's account will be used to launch the application instead of the launching user. Thank you very much!

Hi,
Im having the frame duration.Can we find frame rate by using this duration?
|
|
|
|
|
rate = 1.0/duration.
That's it, isn't it?

|

yep.. be care to use the same units of time. say if the frame duration is 100 milliseconds, then frame rate (per second) -> 1000 /100 = 10
|
|
|
|
|
Well, my answer was accurate...
1/100ms = 1/(0.1s) = 10 (per/s) = 10Hz.
But you're right, he will have to be careful about units!

Hi all,
I am trying to get a value from registry.but it gives 234 error code.That value will contain only a few digits. I have allocated size of 1000. But it is giving the same error code.Can anyone please help me?
Here is the code:
HKEY hkey1,hkey2;
DWORD dwData = REG_SZ;
DWORD dwSize;
char szChk[102];
if(RegOpenKeyEx(HKEY_LOCAL_MACHINE, "SOFTWARE\\Test",0, KEY_QUERY_VALUE,&hkey1))
return;
if(RegQueryValueEx(hkey1,"CHECK",NULL, &dwData, (LPBYTE)szCHK,&dwSize))
return;
Thanks,
|

The dwSize is an in_out parameter, meaning you have to specify the initial size of the buffer and the function after executing will return the actual size of the data.
So do this -
DWORD dwSize = 102;
|
|
|
|
|
no... its not working... again it is giving same error code
|
|
|
|
|
Please see an example[^] here 
Do not forget to release the memory in that example
(free(PerfData) at the ending of the main()).virtual void BeHappy() = 0;
|
|
|
|
|
Try to init your size-variable :
char szChk[102];
DWORD dwSize(sizeof(szChk)); virtual void BeHappy() = 0;
|
|
|
|
|
On closer inspection of your code, RegOpenKeyEx return ERROR_SUCCESS if successful.
The value of ERROR_SUCCESS is 0.
This means RegOpenKeyEx in your code has failed.
Change your if statement to check if the return value is ERROR_SUCCESS.
Please read the documentation on what each function returns.

It's not necessarily an error. RegQueryValueEx() can return ERROR_MORE_DATA. Read the docs to find out when and why this happens."One man's wage rise is another man's price increase." - Harold Wilson

I reference this Using the Windows 2000/XP Object Selection Dialog[^]. It's great article, but what i need is to get specified user list or group, such as "administrators" group, and all users in this groups, what should i set with the filter？
Say:
1. "administrators" group
2. users in "administrators" group
3. "users" group
4. users in "users" group
In a word, my purpose is to get only 1&&2&&3&&4, NOT all the users and groups in local PC, what should i do set with the filter?One day a pretty girl asked me:"Do u think you are handsome?" "I don't think so!".She gave a slap in my face:"Why lying?"...
|
|
|
|

i am not clearing with your question.
are you want current user or all details of user.
|
|
|
|
|
| yes, i only want to get all user name in a specified group. Say, user1, user2 are both administrator on local PC, i want to get their names and save the strings into a list. So do "users" group. One day a pretty girl asked me:"Do u think you are handsome?" "I don't think so!".She gave a slap in my face:"Why lying?"...

| Thank you for your reply, i know the two API. But i still want to use the system pick up dialog to finish my work. I just have no idea for set the filter. One day a pretty girl asked me:"Do u think you are handsome?" "I don't think so!".She gave a slap in my face:"Why lying?"...
|
|

|
|
| you should filter the needed persons out of the list. Press F1 for help or google it.

| I don't know what the needed persons are, the user press a button on my application will invoke the pick up dialog. My purpose is, no matter what operation user do on the dialog, it will only return "administrators" or "users". One day a pretty girl asked me:"Do u think you are handsome?"

Not being able to read Korean, I can't judge if the article is good or not, but there is sample code there for you to follow.
Have you tried following it? If so, what difficulties did you face? It's not reasonable to expect someone to put more effort into answering your question than you did asking and researching it. (By appearances - you may have put LOTS of work in)
I would also disencourage you from creating gifs. There were legal issues, and pgms have all the advantages of gif, with many advantages (ie, alpha channel).
Good luck,

How do I get the base class name of a derived class? I tried using typeid but that only gives me the name of the derived class, not the base class. I have a array that stores many different objects and I am looking for one that is derived from a particular Base class. For example, I did the following:
class A { };
class B : A { };
class C { };
A* pA = null;
B* pB = array[hashValue]; //contains objects of type A, B, and C
if (typeid(*pB) == typeid(A))
//pB is derived from Class A
What function do I need to call in order to get the correct base class?

I don't know what your "array" is, but you can't put objects of different types in a C++ array or in an STL container. You can put pointers to objects in the same inheritance hierarchy in, but then you know what the base class is.
Evidently, your array is some special container you wrote or found somewhere. It isn't clear how it works or what the return type of array[] is. It obviously can't be A*, B*, or C*. Knowing this is necessary to figuring out how to deal with it. Some possibilities are a discriminated union or boost::any.Please do not read this signature.
