View 2 RepliesEssentially what I'm trying to do is read a particular line of text from an integrated web browser (webbrowser1) into a textbox. The user will enter an id number into a textbox which will automatically search the online database search that will be open in webbrowser1. What I then want to do is read the resulting html text into particular textboxes.

View 1 RepliesI have a multitude of VB .NET programs that generate reports in Excel that I populate from an SQL Database locally. My boss wants me to port all these to ASP.net so that users could then access these reports with dynamicly generated results on a browser page.Before jumping onto imbeding Excel objects using ASP.NET from the code I have in VB .NET I was wondering on what kind of approach to use. What could be the most effective way to convert/display these reports in real time to the user via a Browser?

I'm trying to create a label that displays sensor output readings. These are small labels inside a picturebox that has a real time graph of the sensors. I'm trying to make the labels transparent or semi-transparent in order to see the entire graph. Setting the labels background color property to transparent only gives the labels the same color property of the picturebox not the actual images of the picture box. I have set the label.parent = picturebox1.
View 1 RepliesI started programming in VB2008 couple of weeks ago (I'm using the express version) and I'm getting stumped by this ridiculously simple problem. I am trying to retrieve varying parameters from an external application and display their values in real time on a windows form control e.g. a label or text box. I already know what class and methods to reference for that, however I can only display instantaneous values (unless I use a .click event handler, but thats foolish I want them displayed without my intervention) I tried writing a loop in form load event handler but that prevents the form from loading. I also tried a loop in another module but that doesn't work either.
View 2 RepliesHBasically I will have two forms. Form1 will control form2 which is the media display. Form2 will give back the media status and info back to form1 in someway. I was thinking of creating properties in form2 and having form1 polling these values to display the elapse run time etc... ideally i wish to have form2 somehow send events back with data when it values gets updated.
View 1 RepliesI recieved a gift recently visual studio 2010 ultimate a nice suprise I have been repairing and building PC's and networks for years working in local shops and buisnesses, but always wanted to learn programming so my GF purchased this for me nice suprise. So here is my beginner question. I am making a program that will take check info ( check number, amount, date and person or buisness wrote to). I have no plans on using it just trying to learn variable structures and arrays and thought this type of program was a good start. Now I would like to take the text of a text box in runtime and use that to input a new check number into the variable structure. Just so I am not confusing anyone I will write the basic code

So what I would like to do is use a textox labeled check number to add check numbers into the checkrecord structure instead of having to add them into the code manually is this possible?

I have built my own browser 9see attached code) however I would like to modify the code so that textbox1 reads a txt file at start and uses the contents of that text file to navigate to a URL of equal value to the text with in that text file. All this should happen at the launch of the web browser form. Example of the text file contents would be [URL] Code as follows:

I have made a kiosk type software (for my 7 year old daughter so she can only do what I want her to do on one of our computers)
1. I have a toolstripcombobox that will be where she puts in the url's. I need information on keeping the history of where she goes? So when she clicks the arrow to the right it lists all the sites she has been to.
2. Right now, the webbrowser navigates to where the url is (www. vbdotnetforums.com), but when you click a link it dosn't update the textbox with the new url [URL]. It just stays at the first url.... Anyone know how to fix this?
3. Any help being able to add tabs and load the tab with the url like internet explorer?
I have a form with many textboxes. I would like to disable the operation of user interaction with 2 or more textboxes but i would like to assign some text to it. I cannot figure it out a way to do it ...

When i run it the textbox goes "read-only" but the value 0 is not shown. Why ?

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.
