Yes, it's possible, but only if the mother board supports it. Unless the mother board is willing to turn itself on, it's not really possible. Doing it via VB.NET will only work if the code is running on another machine, and the machine being switched on has mother board features that your code can access.
Unless your code drives a robot that pushes the power button.

Some motherboards have wake on LAN, I'd expect those can be started with LAN activity. No, I have no code, I think it's a wild goose chase in most cases.

Try docking your controls so that they maintain equal amount of form space.
Trinity: Neo... nobody has ever done this before.
Neo: That's why it's going to work.

You need to set the anchor property on your controls, so they size themselves automatically.

You would use the DateTime.Subtract method.
Dim StartDate As New System.DateTime(2007, 6, 11, 12, 0, 0)
Dim EndDate As New System.DateTime(2007, 7, 12, 12, 0, 0)
Dim TotalDate As System.TimeSpan
TotalDate = EndDate.Subtract(StartDate)
MsgBox(TotalDate.TotalDays & "Days Left")
Trinity: Neo... nobody has ever done this before.
Neo: That's why it's going to work.
|
|
|
|
|
I get an error.
Type "System.TimeSpanTotalDate" is not defined.
So what can i do?

It should work. Could you please post your code?

It work now.
Dim StartDate As New System.DateTime(2007, 6, 11, 12, 0, 0)
Dim EndDate As New System.DateTime(2007, 7, 7, 12, 0, 0)
Dim TotalDate As System.TimeSpan = EndDate.Subtract(StartDate)
response.Write(TotalDate.TotalDays & " days left")
By the way I want to get day and time left like N7W "24 days nad 2hours left"

substituting minutes, seconds, days, or whatever interval you are looking for in the place of 'hours'. Well, in Visual Basic .NET there are two main ways to achieve this result; the DateDiff function or through the TimeSpan structure.
Both of these methods are equally valid, where they overlap in functionality, but each of them has a couple of unique features. Despite their similar functions, the core difference between the two is that DateDiff is a function, so you need to call it every time you need to retrieve a value, whereas TimeSpan is a structure that is created once and then you just work with its various members as needed.
Using DateDiff, you call it with different date interval parameters to retrieve the appropriate value:
Dim D1, D2 As Date
D1 = Date.Now
D2 = 11/9/2007 'DateDiff
Console.WriteLine("DateDiff")
Console.WriteLine()
Console.WriteLine("{0} Days", _DateDiff(DateInterval.Day, D1, D2))
Console.WriteLine("{0} Hours", _DateDiff(DateInterval.Hour, D1, D2))
Console.WriteLine("{0} Minutes", _DateDiff(DateInterval.Minute, D1, D2))
Console.WriteLine("{0} Seconds", _DateDiff(DateInterval.Second, D1, D2))
Console.WriteLine()
Hope this code will Help you.
Regards,
Satips.

Conversion from 'Double' to 'Date' requires calling the 'Date.FromOADate' method.

Hey guys I'm writing a program in VS2005 using VB.NET...I'm having a very strange issue. I'm running a fairly lengthy process where I show a progress bar and an estimation of the time remaining...when I run my project while VS is open, the process runs at a normal pace, even if i start the process from the bin and not from VS itself...if i kill VS and then run the process, it becomes unbelievably slow, has anyone else had this problem? Any ideas on how to fix it?
Apparently it's not OK to start a bonfire of Microsoft products in the aisles of CompUSA even though the Linuxrulz web site says so

|
|
Have you tried running the process, with all antivirus programs unloaded ?
My advice is free, and you may get what you paid for.

I don't use any anti virus software, I us a disk image that I can dynamically add to, so any time I get a virus or anything of that sort, I just reinstall off of my image...takes about 5 minutes.
It almost seems that VS somehow gives .NET processes a boost or something...I'm not sure. It's very strange, but the rate of speed is drastically different when not running VS, so much so that I think it would almost make the program unusable unless VS was running in the background the entire time...The tool is a data transfer program for SQLServer 2005. On average with VS running, it transfers roughly 150 records per second...when i shut VS down, the rate drops to roughly 20 records per second.

Hmmm I figured it out...It is because with VS open I also have a live connection to my database...if i leave my connection open instead of closing it each time i have finished transferring data i don't have this issue. seems a little strange considering connection pooling is supposed to help with this, but apparently doesn't help all that much.

Generally speaking, when using databases it is always faster to have as few separate calls and as few separate connections to the db as possible. Don't know why, but so I hear, and so I have experienced myself.
Good to hear your problem was solved

While I understand how to use a for next loop, I cannot work the integer (eg. 1 to 10) into the name of an object. For instance, I would like to create a for next loop for the following code
ckfld1.Checked = False
ckfld2.Checked = False
ckfld3.Checked = False
ckfld4.Checked = False
ckfld5.Checked = False
ckfld6.Checked = False
ckfld7.Checked = False
ckfld8.Checked = False
ckfld9.Checked = False
ckfld10.Checked = False
Could someone show me how to do this?
I tried the following but it does not work.
For x As Integer = 1 To 10
dim c as new checkbox
c.name = "ckfld" & x
c.checked = false
Next
Any help is appreciated. I am using vs 2005.
Thanks
Marc

Try this instead:
For Each Box As CheckBox In Me.Controls
Box.Checked = True
Next
This finds all CheckBoxes in your form and checks them. You can also do the same using a Panel or GroupBox.
Trinity: Neo... nobody has ever done this before.
Neo: That's why it's going to work.
|
|
|
|
|
The problem is that there will be checkboxes that should not be affected by the for next loop, which is why I was trying to accomplish this the other way.
Is it possible to do it the other way?
|
|
|
|
|
In that case you would put the CheckBoxes you do want to be checked in a Panel.
