I have searched all over and can not find the printqueue anywhere. I'm using VS 2008 Pro, and .NET 3.5. I'm writting in Visual Basic.I create my document then send it to a previous selected printer. I do not give the user a printdialog I handle all the settings in the code. My problem is when the printer is not online, it triggers an unhandled exception. I would like to check the status of the printer just before the printdoc is sent, so that I can handle what to do when the printer is offline.

it doesnt work .I read this in another post:
"There are several possible approaches; you can try to identify something other than the id, such as the element's name, class, tag name, etc. Another approach is to identify a nearby element, whether it's a sibling, child, parent, etc. that is easily identified (it has an id, or is in some other way unique) and get to the element that you want relative to the element you know you can find. For example, maybe the element is the only child of a </div> tag or a </span> tag that does have an id." So this is the parent to that code:
<div align="center" style="padding:5px;border-style:solid;background:#ccc;border-color: #000;border-width:1px 1px 0px 1px;"><input type="button" class="w10pt" style="width:136px;display:block;font-weight:700;" value="Login" onclick="location.href='/start/login.htm?arg1=1'"></div>[code].....

View 5 RepliesI have to send a sequence of video frames over UDP as fast and real-time as possible and while I got the basics working, I am running into all sorts of difficulties. Some of my goals:Data will normally be sent over dial-up (hence UDP instead of TCP), but also needs to support fast Ethernet.It's OK to occasionally drop frames (hence UDP instead of TCP).Need low latency. The frame the remote receives should be one that was recently sent (no more than a few frames waiting in buffers).I need to be able to detect the effective bandwidth so that I can compress the frames more or less to keep frame rate up.I break up frame data into one or more datagrams of about 500 bytes and each has a sequence number and other info. The receiver reassembles the entire frame and detects if any datagrams are missing.If the receiver detects more than a certain percentage of dropped frames (e.g. 50% over the last 10 frames), I send a TCP message to the sender to slow down by 50%. Sender than slowly increases speed by 5% each subsequent frame.Using System.Net.Sockets.UdpClient to send and receive the data.I have a separate TCP channel used for control messages back to sender.My main difficulty right now is detecting the effective bandwidth and dealing with latency, especially over dial-up (max ~4,000 bytes/sec). For example, if I try to send 100,000 bytes/second using TcpClient.Send() they ALL seem to arrive (no dropped datagrams) but with large latency by the time last datagram arrives. I think the TcpClient.Send() function is blocking until the buffer is able to send which messes up my current algorithm.
Can anybody point me to any sources of information for how to:Detect actual bandwidth over UDP.A better algorithm for dynamically adjusting bandwidth to suit the available pipe.Send data smoothly at the desired bandwidth.A way to detect and keep latency down to a minimum.I have been spinning my wheels over the last week and every time I solve one problem it seems another rears up is head.

View 1 RepliesI created a form with MS Access with some dropdown menus and some check boxes. The main reason is for when the user select a check box or an option from the dropdown menu a specific phrase will appear on a Note box I created on the bottom of the form. Where I am having the problem is because I added a Text Box in Access where the user can type something in it. What I need is when something is typed inside of the text box the content should be mirrored inside of the Note Box on the bottom of the form. I was able to create the functions using VB for the dropdown menus and the check boxes but for the Free Form Text Box I dont know how to mirror the real time texting.

View 2 RepliesI work for a company that produces accident reconstruction software. We have a vehicle dynamics program that realistically simulates the motion of a vehicle (position and rotation of car and steer angle of individual wheels, etc).
All the positions of the car are stored into an array called AMTN. The vehicle dynamics program can calculate positions at time steps finer than .005 secs (200 FPS).
I need to represent this data in real time, and so far I have not been able to accomplish this. I have tried doing this in Excel/VBA, VB6, and am currently trying to do it in VB.NET.
I have used a whole plethora of timers and counters as well as different methods of drawing lines on graphics linked to images linked to picture boxes, etc. My animation program writes/clears the screen correctly, but there is clearly some sort of lag in either the timer or writing method. I have scaled it down to 25 FPS and there is still a lag.
Here is an example of what I am trying to do with each tick of the timer:
Code:
Sub Timer1_Tick1(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick
MyGraphic.Clear(Color.White)
[Code].....
With each tick of the timer, the graphic is cleared, lines representing each side of the car are drawn onto the graphic, and the picturebox is then assigned to the image, which is linked to the graphic. This is just like how your asteroids program works.
Do I need to change my method? Should I use sprites? Or would it be better for me to create images/bitmaps of the animation beforehand and simply flip through them with a timer?
I'm thinking that creating the images beforehand might work because I do not have to calculate the vehicle's position as it is predetermined by my AMTN matrix.
if there is a more efficient way of displaying my vehicle on the screen that would allow for greater FPS, etc.
