When can I use MsgBox

Hi There,
I want to know under what circumstances I can use or not use MsgBox in a Visual Studio 2008 SqlServer Project?
E.g. I cannot use MsgBox in an deployed assembly, that causes something like: attempt to use resources forbidden by the CLR host.
But when is this not forbidden? In other words, when can I use the MsgBox function without throwing an error?
Regards, Jos
I'll be back

I think the first important question is why you want to show a message box? Typically SQL CLR applications run on the database service in the background and don't have a UI component. Even if you were to somehow get that command to work, I don't believe
there's any UI loop which allow it to display correctly.
In more general terms, the error you're getting is related to SQL CLR sercurity. There's a great article about how security works for SQL CLR
here (notice the Next and Previous links at the bottom to read more). That may help you with some of what you're seeing, but for your specific case, as far as I know it is
not possible to display a message box from a SqlServier project.

When can I use Inspection Type 05

When can I use Inspection Type 05 - Inspection for Other Goods Receipt. Please suggest me which scenario I can use 05.
Thanks

Hi
05 is not directly assigned to any movement type.It is like 08 inspection type.
best thing is that 05 is stock relevent inspection type.
Just to share with you :
1.When you want to revert the material stock posting done through UD screen like 553(scrape)
reversal of stock posting -554- can be done through activating 05 inspection type.
2.when using a project systems Inspection lot of 05 generate after 101 mvt type.
3.during sales & sales return if you assign the 05 inspection type for tha material & for
655 GD returns QI -->you can activate 05 ........this creates lot of 05.
etc
mostly its use for Inspection where you want stock posting to be done.

When can I use an iphone 5s in South Korea??

Hi there,
I have used many kinds of Apple products for last 5 years such as iphone 3g, 4, 4s, macbook pro, etc in Australia.
however, after I graduated for a uni in AU, I have come back to my country, South Korea. so, I tried to get an iPhone 5s but, it is impossible now in my country.
I would like to know when I can get an iphone 5s in Korea. I checked the price unlocked version of iphone 5s in many other countries such as Hongkong, AU, US, but too expensive to get one via the websites.
SO, anyone can let me know when I can have one?
Thanks,
Jin

No users here will know when Apple will release the iPhone 5s to other countries.
The recent Apple keynote mentioned in Dec that some other countries will follow, but no country specific.

When can I use my WSABUF and overlapped structures when using WSASendTo on an overlapped socket

When calling WSASendto on a UDP socket that is overlapped it is difficult to get the right understanding from the documentation provided in MSDN.
The question is, will WSASento copy the content of my WSABUF's so I can use them again? (Even before the complete routine and the event is signalled)
According to http://windowssdk.msdn.microsoft.com/en-us/library/ms741693.aspx this is the case:
"The array of WSABUF structures indicated by the lpBuffers parameter is transient. If this operation is completed in an overlapped manner, it is the service provider must capture these WSABUF structures before returning from this call. This enables applications to build stack-based WSABUF arrays."
But reading a Microsoft book in chapter 6 conserning Winsock and QOS:
"On the sending side, applications use WSASend or WSASendTO to supply pointers to filled buffers and then agree not to disturb the buffers in any way until the network has consumed the buffer's contents"
Can I call WSASendTo again before completion of the last WSASenTo is indicated ?
Do I have to give a new WSABUF every time ? Or can I reuse it ?
Can I reuse the Overlapped structur as well ? Or do I need to wait for the completion for the last WSASendTo ?
Background information:
I am doing an application that is quite time critical. I use one sending UDP socket and a receiving UDP socket. Both of them are asyncron. The receiving socket is working fine. The reason for chosing asyncron (overlapped) for the sending socket is because sometimes a WSAsendto can last 3,5 second if the ip that I wish to send to is unknown to to PC. But I need to send the next UDP packet in around 1msek. In normal conditions it only takes around 50usek to calls WSASendto.
I hope somebody can help me
Best regards
Flemming

Thanks for the answer. But I will like to dig a little bit in it to be absolutely sure.
The chapter 6 of the Microsoft book can be found at http://www.thaifast.com/Microsoft_Books/Sample/02783006.pdf
This chapter is dealing with Winsock 2 and the quote is from page 12 (or 74 according to print) is about overlapped I/O.
I am considering code like this (note that the overlapped is a menber and initiated once in the constructor, the menber function this is called in can be called before the actual send is finished(that is before the event on the overlapped structure is signalled), can the system handle this ?). Actually if the UDP message is send or not is not interesting for me, because timeouts on the respons on the message are handled somewhere else in my program, the reason for this is that I use UDP and the packets could get lost somewhere in the network anyway:
                WSABUF wsaBuffer;
                LPWSABUF lpBuffers;
                lpBuffers = &wsaBuffer ;
                wsaBuffer.len = nBufLen;
                char *pTempBuf = new char[nBufLen];
                for (int i = 0; i < nBufLen;i++)
                        pTempBuf = lpBuf;
                wsaBuffer.buf = pTempBuf;
                DWORD noOfBytesSend = 0xffffffff;
                int socketSize = sizeof(sockAddr);
                nResult = WSASendTo(m_hSocket,lpBuffers,1,&noOfBytesSend,0,(SOCKADDR*)&sockAddr,socketSize,&m_overLappedSend,,NULL);
                if (nResult != 0)
                        int error = WSAGetLastError();
            if (error == WSA_IO_PENDING)
                                TRACE("Output is pending\n");
                        TRACE("SendTo returned %d error %d\n",nResult,error);
                delete [] pTempBuf;
                pTempBuf = NULL;
I'd put my money on the MSDN documentation over a single book. The documentation for WSASendTo has been around, scrutinized, and edit for years. If it says you can use stack memory in a call to WSASendTo that would mean that you're free to do whatever you want with the memory given to WSASentTo as soon as WSASendTo returns.
I'll see if I can dig up an exact (rather than inferring from the documentation) what's really going on with WSASendTo.

When can I use iMessage? How do I restrict it to only use iMessage?

I have to pay 30 cents per text, which is a ripoff, and pretty much everyone I know uses an iPhone or iPod touch, so I want to just use iMessage with them. For some reason, though, I can only sometimes send iMessages to iOS users. I can never send them to my friend, who has an iPhone 4 running iOS 5. I can typically send iMessages to my parents but not always, it sometimes only lets me send by paid SMS. They definitely have iMessage enabled. Maybe I'm not choosing the right address to send it to?
So are you supposed to enter someone's phone number, and it'll know whether or not they have iOS and use iMessage if they have it, or do you have to enter their email address that they set as their iMessage address?
Also, is there a way to just force it to only use iMessage? I don't really want to send or receive paid text messages under any circumstance. Come on, 30 cents to send a few bytes is ridiculous.

I tried that, thinking it was exactly what I wanted, but it still sends stuff as SMS (green bubble).

Dear Apple, When can I use iTunes again?

I upgraded to version 7.6 and had problems playing any file. I had to revert back to 7.5. I waited until 7.6.1 came out and upgraded to that version. Things were fine. Or so I thought. After purchasing a movie rental the other night, I had the same exact issues I had using 7.6. I'd click to play a file and the progress bar would not move but, the file played. The beachball began it's thing and iTunes froze. Force quits aplenty.
Now I am at the same place. But alas, I cannot revert back to 7.5 as Apple must have done something to prevent that. So, I am stuck with no iTunes. I can't play the numerous iTunes I purchased nor can I play video files, movie purchases or movie rentals.
