Dear friend, this forum is to help to solve your technical problem, no one is here to spoon feed you.
So don't ask for the whole program again in this forum.
And please read the the instruction, how to ask questions [^]
Please check with this link, it will help you related to DFS [^]

The running time of the depth first search algorithm is O(n) where n is the number of nodes in your graph.
Breadth-first search avoids backtracking, and also has a running time of O(n).
You can find programs for both of these algorithms through Google.

my questions:
how to implement draging for the system icons,just like My Computer,My Document and etc, into other directories in my own design app.as i know,exploer just create a icon-link for the operations,how can i emulate this operation, thank you very much.

Hi There.
My problem is:
I am able to send messages to the queue using my machines name, but am unable to do the same with IP Add.
For example:
qInfo->PathName = "MYCOMPUTER\\private$\\PanBQueue"; works fine...
qInfo->PathName = "IP ADDRESS\\private$\\PanBQueue"; Fails...
Thanks

Did you check the error you are getting?
Please check that first?

I do not get any error message as such. But when I try to open the queue...i.e.,
qDest = qInfo->Open(MQ_SEND_ACCESS, MQ_DENY_NONE);
I got an exception. Please let me know, in case you need any further details.
Thanks anyway for your effort.
|
|
|
|
|
Please tell me whats the exception?
And i hope u checked the getLastError [^]

catch(_com_error &e)
e.Source() -> MSMQQueueInfo
e.Description() -> The queue path name specified is invalid.
|
|
|
|
|
I think you are using MQPathNameToFormatName,
if so then DNS name is correct. It wont accept IPAddress.
So i think, firstly IP address should be changed to corresponding DNS name [^]

More info:
I want to place a message from MachineA to MachineB's Message Queue.
So, I have to access the message queue on MachineB using its IP Address itself.
Any pointers/suggestions will be highly appretiated.
Thanks.

As i suggested earlier, get the DNS name from IPadress using gethostbyaddr API [^]
And then pass DNS name with the path. Now your problem solved,isn't it?

Hi all,
I am new to the C Programming. Currently, I am using the 3-axis accelerometer MMA7260QT, P18F2620 and GSM Module iWOW TR 900 for my project.
MMA7260QT
MMA7260QT is the accelerometer that detect the 3-axis: X, Y and Z-axis.
P18F2620
P18F2620 is used to detect the acceleration signal sent by MMA7260QT in 3-axis. Once there is a vibration, it will automatically retrieve the Cell-ID. Then, it will convert the Cell-ID into the decimal form and send out to GSM Module iWOW TR900.
iWOW TR 900
iWOW TR 900 is to get whatever info from P18F2620 and send out using GSM.
The objective of my project is to detect the acceleration in 3 axis.
Once there is the vibration, it will send the signal to the P18F2620. P18F2620 will then automatically retrieve the Cell ID, convert it into the decimal form, eg. 15322-32 to be send out via SMS.
I have write the simple C code to send the fixed Cell ID. I have tested my program. It is able to send the fixed Cell ID out. However, there is something wrong with my codes. Firstly, it is still unable to detect the acceleration. Secondly, I still unable to write the code to get the Cell ID automatically. The iWOW module is only recognised AT command.
I am using the AT+CREG=2 and AT+CREG? in order to get the Cell ID. The reply on the hyper terminal is like this.
AT+CREG=2
OK
AT+CREG?
+CREG: 2,1,"0020","DB27"
I will need to store the 0020 and DB20 (Hex form) and convert it into decimal form 56103-32 to be sent out using the GSM module. All these have to be done using C program.
Here is my code snippet. Please correct me if anything I wrote wrongly in my code. Thanks

Please reformat your message with < pre > < /pre > tags, the chances that anyone reads your code more detailed and helps you will be higher.

May I know why I need to reformat my message with

Please, read this[^]. Putting your code inside <pre></pre> tags will make it much more readable (now, your code is very hard to read).

Are you referring to the code below?
char MESS4[21] = {"CellID | 15831-32\n\x1A"}; //Example of sending CellID
This code is set as the prefix value to simulate the sending of Cell ID via SMS. It does not simulate the retrieving of the Cell ID automatically.

No, I was referring to your question:
[quote]

[/quote]
And the answer is obviously... yes. Now your code in the original question is much more readable and the help you need will come easily. Just keep an eye to new answers hanging on your original message, that's the good point of the tree-view of the threads.
Regards.

On the other hand, I can not help you so much because I have not used that components, but I am going to make you some questions (and the answer to this points should be added in the original question) trying to isolate where the problem is:
- Have you tested your programm?
- You say want you want/need to have, but what are you actually getting?
- Is there any compiler errors? If yes, which ones and referred to which line?
- A short explanation about what each external component do and how it is supposed that C interact with them, would not be bad.
The point is: you are using very specifical components, that can be the source of your "not working" status, and this has not so much with C contents, so it may happen that the people that could help you with the C programm doesn't have the needed information about the extern components you are using.
This can be translated to: Your code may be "gramatically" correct, but the parameters for the interaction with the other components are not correct. So the program does not do what you want it to do.
I have found this places using google. Take a look, they may eventually help you:
