Basically needs to get the temp and the clock speed from a database and desplay it in a graph.
Here is a download of the project file : [URL] and if you can not be bothered downloading it here is a link to the code its self:[URL]
I have a codes that calculates DownLoad speed and UpLoad speed kb/s. I would like to implement this kind. I also want to put such kind of graph. Any article or links where can I start building my own like that.

View 1 RepliesAm trying to copy contents of file temp.fxl to temp.seq. I want them to look exactly them. I don't want to copy the file though. I use the following code
Dim fs As New FileStream("c:\fxlate\output\temp.fxl", FileMode.Open, FileAccess.Read)
Dim s As New StreamReader(fs)

With such simple code, the last line in temp.seq is truncated as attached and the size of the file is smaller than temp.fxl. See attached files. What do I need to do on the above code. Is VB.NET failing to write 1024 characters on one line.
I am new to vb and I am required to plot a graph in vb. I need to get data from a text file to plot a polar graph of Wind Direction vs Wind Speed. But opening the file from a text file is in a string format, and when i tried to convert to a double, it gives the error:

I'm a totally newb to VB and I want to do this. I want to do display system clock into a textbox. The trick is that I want it to be synchronized with the Windows XP clock. I want to have something like +/- 100 ms accuracy.
Each 'second' change will trigger an output pin to ground into the parallel port. This is very important that the 'second' change in the same time the Windows XP second change. Do not care about the parallel output thing, I'm nearly there. My main concern is the synchronisation with Windows clock.
In my code, I've added a counter that increment +1 at each 'second' change. So, when the 'n' value will reach a determined value, it will trigger another event.

I searched on the net and I found a thing about NIST time server.. Maybe this could be an otpion, but I have even no idea about how using it... I'm a total newb, but I'm ready to learn. So, please use simple language, no hard to understand acronym etc.
Are these results expected or am I conducting my benchmarks incorrectly: Benchmark: Query on 363,264 records takes Access 27s to run (Over network) ADO.net: 54 seconds (Over network) ASP.NET: 34s (Local on server) The last two have identical VB.net code. All three run the same query on the same DB.

ive been struggling on this portion of my code for almost 3 days with no luck. i have a database containing a list of transactions (in this case, the product name, quantity and date of sale). I want to plot a graph for each product showing the amount sold each month for the past 12 months. The functions to calculate these values are working fine. but my problem is this:
each tab page is named after the product name:
TabControl_SaleOfProducts.TabPages.Add(
"TabPage_"
& ProductName, Item)
and then to this tab page i want to add the graph. but i cannot reference the newly created tab page?
Is it possible to create a graph by using data from a database?

View 6 RepliesI have a few questions regarding database speed issues, I want to learn more on this subject. I searched the internet a bit but could not find an answer that satisfied enough me so I thought i try here. I have used adodb for quite a while but never were in the need of doing it the fastest way. That changed a bit.Is there information on the internet or can you provide me with information that illustrates what the cost is of doing a while not .eof loop to populate a dropdownlistbox with a lot of values or using a different approach? what are the faster approaches? I understand it depends on the situation but i am interested in a summary of some ball park figures. Just to illustrate what is better to use in certain situations.

View 2 RepliesI am working on an application that ties into a SQL database on the back end. Currently the main form contains a series of combo boxes (Graph type, data format, location, and customer), two date pickers, and a button to launch the selections in a new form. Everything works just fine except there are a couple of things I can't seem to accomplish.
Example Data:
[CODE]...........
Case Select (with commented out lines for variations attempted):
[CODE]..........
1) I would like to be able to use some sort of case statement to color the bars in my chart based on value. I have tried approaching this in a couple of different ways but neither of the options seem to work. First, I tried this (the If Not is used because depending on what values are passed to the stored procedure in SQL, different columns will be returned):
[CODE]..........
Only one series is created with this method, so I can see how/why a Select Case would set all bars the same color. I have also tried creating a series for each row in the returned dataset but it results in 22 bars of different colors, for each of the rows (484 bars):
[CODE]..........
So is there any way to modify the second set of code there to only select the value from the "Percent TMHB" cell that corresponds with Row(i), rather than ALL values from the "Percent TMHB" column for EACH Row(i)?
2) Since I am drawing/creating these graphs in a new window, is there any way to also create a new timer on the "newFrm" and have the tick refresh the data? I've struggled with this but I feel like it should be easy. Say someone chooses a "TMHB", "Percentage", "Chicago", "All" (Graph type, data format, location, customer) and launches the graph, which opens in a new window, then they want to do "TMHB", "Percentage", "LA", "All" and have both windows up, refreshing automatically throughout the day. Can I somehow store the SelectCommand.Parameters values in the new form/timer so that it will query the database again every 5 minutes?
Example code for the StoredProcedure and creating the new form:
If combo_GraphType.SelectedItem = "TMHB" Then
Dim newFrm As New Form
Dim newChart As New Chart

I have event handlers to update datatables when input is changed on a form. When the form is loaded some objects are programatically changed depending on data in the datatables.pecifically, default values are populated using code. These changes cause events to fire causing data (mostly null when the first event fires) to be saved causing errors.

How can I get it to send the old changes and the new changes. I know I will need to somehow temp store the old values to use them in the email, but I can't figure out how to do it. I don't want to store them in an actual database table.
