I want to use a database table as a a queue...but the processing of these messages cannot be done from the database.I have a table that stores the requests i get from a .Net component. I now have to read the data from these tables and make http calls to 2 webservices. Based on the response received from the webservices, the data gets archived or deleted.I had a few specific questions:
1. How do i make sure that if i pick a record for processing and the http call fails I should be able to go on to the next record, and then come back to this record at the end of the run
2. Is there an alternative to using the database as a queue(like MSMQ etc.), which option is better
3. I want to maintain an audit trail of the record status. Is creating a trigger to log the changes before the edit the best way to do it?
I have question about the firing of events in vb. Lets say if I have timer that fires every 10 seconds and then I also have eventhandler that is listening to some other event (like message arrived in queue and now event fires to process it). Then how does vb handles them if the program is currently processing Timer1 and message arrive event fires or vice versa? Does it complete the current processing and then jump to the next event or just switch in the middle to the new event and then finishes that and then resumes back to the first one?

I have an array that I'm basically treating like a queue (FIFO)I'm trying to decide the fastest way to implement this.Currently I'm just iterating through and shifting everything up an element and placing the new data @ 0. This was fine when I was dealing with 1000 element arrays, but now I'm moving up to 100k element arrays and it's stalling my code.It has been useful to have the data in array form because I'm using the array.sort method and a few other statistical modifications that use the element number (of the sorted list) to work.I'm not sure if VB lists are (like Java) pointer based, and if so I think that shifting pointers would execute faster than my current approach.My question is, if I did move to a list would it a) be faster, and b) is there a way to call a quick sort from the list class?If the execution time is the same for the array vs. list is there a better way to make a FIFO structure in VB?

View 3 RepliesI am currently creating a FTPWebrequest to handle my uploading (the webrequest section of my function is below). At the moment my code loops through this webrequest section for each file - giving the file path of each file in the string "CompleteLocalPath". For each file it creates a webrequest and giving the required file path, uploading the file using a file stream, and then closing the stream. This works, but seems to take quite a long time. Can you recommend a more efficient way? Perhaps by using one webrequest but modifying the upload path?

I have a program that is using API's to send mouse events and keyboard events to another application that is running. I need to know how to tell if there are any messages left to process for that window after I have click on a button or moved to the next field. I need to know this so I don't send any more mouse or keyboard events until it has finishing processing everything in its message queue. An example is that I click out of the key field and the form has to go out and read a client record. This may take a second or two, so I need to wait until the form is ready for more input.

I thought of using the queue object as it handles things on a FIFO out basis and I'll be adding to the queue as new files arrive.
