Forms :: Transparent Label Over Real Time Graph?
Apr 11, 2011
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.

I have a project to make a GUI using VB.net and retreiving data from an excel spreadsheet every three minutes and draws a graph in real time. The excel file is filled every 3 minutes by a new value (level of water in a tank).As I made started making this interface and I have a problem with retrieving data from a cell of the excel spreadsheet and update this action automatically every three minutes.

Currently, my circuit is connected to a power supply and is connected to the computer via a RS232 cable. Voltage level is extracted and the real-time voltage level is plotted (see attached image) and it will keep movingBut you will realise that there isnt any time shown on the X-axis. I would like to display time in such a way:Each long marker will represent 1 second and there are 4 long marker, which will represent up to 4 seconds.When the (5th second) voltage is sense and the real-time voltage is drawn, i would like the new time (5th second) to replace into the 1st marker postion, the (6th second) to replace the 2nd marker position, so on and so forth. The replacement will continue

I want to draw graph in visual basic 2010 form which changes with time. Just like the CPU usage history graph in the "Windows task manager" dialog box. Thats time vs. usage graph. I want to make applications with that kind of graph.

I have designed a window application that: check the contents of a folder for specific files (HTML)move files to a 'working' diretoryparse each file with webbrowser control to extract datacall webservice to collect additional data
The main form has a large ListBox that displays event messages. What I want is for the application to display the messages as they happen. What seems to be happening is that the application will do everything and then display all of the event messages at once at the very end. pointers on how to write code that will add event messages to the ListBox as they happen?

I 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.

HBasically 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.

I'm trying to make a label control transparent over a Panel control.However by setting the background colour of the label to Transparent, it actually sees right through to the form itself, not the panel as intended.
As an example we use a panel with a background as white, we make the label transparent, however it gets the form�s colour as blue.However, we are using a custom panel control and need the label to be transparent over the panel and not see the forms background.

so i am busy with a mediaplayer ( just for fun ) and everything pretty much works, but one thing doesn't.the thing is ive got 2 labels, the first label needs to show how much ive already played, and the second label needs to show the duration of the media file.example: a media file from 1 hour 32 minutes and 18 second and i have already player 43 minutes and 9 seconds from it, then the first label needs to show 00:43:09 and the second label 01:32:18.

I searched the forums and most of the topics involving this seem to be for Compact Framework. I need a transparent text label which shows an object directly beneath it. In this case, a rectangle. (Visual Studio 2010) I noticed that when I set the label background to transparent it shows the form bg instead of anything between the label and the form. How can I work around this without setting my form background to an image? If I were to make a custom control for it, how would that be achieved?

I making a simple online chat using an ftp server by downloading and uploading text. I use a thread to update the chat log continuously. But it doesn't update in real time. Is there a way to create a server that clients can upload to and download from extremely quickly? How do programs like MSN messenger or better online multiplayer games do it?

I 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.

I 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.

methods/procedures for sending real time data from a VB.net app to a web server (asp.net) for real time display. My question relates to the best method to send the data from the desktop app and the best way to receive and handle the data on the server. I'm not asking for sample code, just some idea of what methods to research. I am currently using a text file upload method but I'm sure there is a more efficient way of achieving this.
