The below code (VB 2008) will check the print queue every milisecond for a job. It will then show the pagecount in a text box. It works great when im printing to a local printer, but As soon as I change my pc default printer to a network printer, I cant capture any data.
View 1 RepliesI am developing an application about a print queue monitoring. I found this code:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
localPrintServer2 = New LocalPrintServer()
defaultPrintQueue2 = LocalPrintServer.GetDefaultPrintQueue()
ht1 = New Hashtable
ht2 = New Hashtable
Timer1.Enabled = True
Timer1.Interval = 50

I have sent print but it never goes inside the loop. There is nothing shows in the Textbox as well. For Each job As PrintSystemJobInfo In jobs. Is there any way to find out which system it is coming from because I have to build a system with the number of prints each user in the system prints and to which printer.
How can I clear the printer queue from VB? if I was doing it manually I would stop spooler service, empty the windowssystem32spoolprinters folder and restart the service

I already tried using the "PrintDocument.SetDevMode". it seems not be working.
1. Detect if my printer is busy, because my code tells the printer to print more pages that it can cope with, so I need to delay the command for 'Print the next page' until the printer has finished printing the previous one.
2. Shift the output to my printer so that it gets printed in it's entirety on the paper, instead of seemingly being anchored to some nebulous point on the A4 page. It starts printing at X = 29mm from the left edge, and Y is 28mm from the top, and stops at X = 22mm from the right edge and Y stops at 22mm from the bottom edge, leaving (aprox) 50mm of X and 50mm of Y unprinted.
3. Get useful information on Bounds, which I'm fairly certain is what I need to control where my printing should start and finish.
I've hunted through this forum, MSDN, 'Help' (a misnomer if ever there was one) the VB Library and one or two other forums, which either baffle me with reams of code or suggest code to try which either just don't work or which doesn't declare all the variables and usually don't suggest what type of variable I need, it's all very frustrating

View 5 RepliesI 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.
View 4 RepliesI 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?
