You can use an unsafe block.

Although there are softwares for this purpose, my aim is to create a windows application which will simply show cpu temperature
for the time intervals I give in , and will display no other options (such as voltage,etc.. which are going to consume computer resources (cpu,ram)). I want it to be simple : just a label of cpu temperature (as I'm having a problem with my cpu temp.)
I've searched the net and find something about the Management Class, but couldn't retrive the temperature..
I guess it should be two or three lines of code to obtain it and I'd be glad to get your help.. thanx

Here's a silly example of one way to use WMI to display processor info.
This uses the WMI Win32_Processor class, but the
Win32_TemperatureProbe Class[^] class could be used.
Seems most hardware doesn't support it though.
Doesn't hurt to try it.
int ProcessorIndex = 0;
ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_Processor");
ManagementObjectCollection.ManagementObjectEnumerator enumerator = searcher.Get().GetEnumerator();
while (enumerator.MoveNext())
{
Console.WriteLine("ProcessorIndex: {0}", ProcessorIndex++);
if (null != enumerator.Current["Name"])
Console.WriteLine("Name: {0}", enumerator.Current["Name"].ToString());
if (null != enumerator.Current["Description"])
Console.WriteLine("Description: {0}", enumerator.Current["Description"].ToString());
if (null != enumerator.Current["NumberOfCores"])
Console.WriteLine("NumberOfCores: {0}", enumerator.Current["NumberOfCores"].ToString());
if (null != enumerator.Current["NumberOfLogicalProcessors"])
Console.WriteLine("NumberOfLogicalProcessors: {0}", enumerator.Current["NumberOfLogicalProcessors"].ToString());
if (null != enumerator.Current["L2CacheSize"])
Console.WriteLine("L2CacheSize: {0} KB", enumerator.Current["L2CacheSize"].ToString());
if (null != enumerator.Current["L2CacheSpeed"])
Console.WriteLine("L2CacheSpeed: {0} MHz", enumerator.Current["L2CacheSpeed"].ToString());
if (null != enumerator.Current["L3CacheSize"])
Console.WriteLine("L3CacheSize: {0} KB", enumerator.Current["L3CacheSize"].ToString());
if (null != enumerator.Current["L3CacheSpeed"])
Console.WriteLine("L3CacheSpeed: {0} MHz", enumerator.Current["L3CacheSpeed"].ToString());
if (null != enumerator.Current["LoadPercentage"])
Console.WriteLine("LoadPercentage: {0}", enumerator.Current["LoadPercentage"].ToString());
Console.WriteLine("------------------------------------------");
}

Hello. I've got a little problem I've been having a hard time solving.
I'm trying to use the web browser control on a windows form to get the html of a frame that the given page contains. I can't just simply use the url of that inner frame, because with each login to this site it has an appended session ID on the url and other such a=b&c=d&e=f nonsense that changes from session to session. Digging through google I found mention of webBrowser1.Document.Window.Frames[0 /*or any other index for that matter, but in my case there is only 1 element*/ ].Document.Body but this threw a System.UnauthorizedAccessException when I tried it.
Ultimately, what I'm going for is a rather simplistic project but it's giving me fits on this point. I'd like to be able to login on this form on ogame.org and have it refresh every five minutes, searching the contents of "mainframe" for the word "hostile" - and if this is found, sound an alarm (system speaker et all), as this would mean one of my planets has an incoming attack, and I know how to do all of this except getting the damn mainframe's source. I know it shouldn't be too hard to do - in my opera browser I can just right click, go to the frame menu, and open it up just fine, and that's the source I want! but I can't get this out of my web browser control. all I can get is--

If anyone knows a thing or two about this windows control and is able to help me I'd be really grateful. I've been working on this all day and can't get it to work because of this one, single problem.
Thanks!

Hi
I am trying to pass data back and forth windows forms but I am having trouble. What I am trying to do is this:
I have a mainForm that has 2 textboxes called plainText and ChiperText. This main form also has a menu bar of different algo to choose from(for instance shift Chiper).
When shift chiper is clicke id launched a new form(shiftchiper.cs). It has some options and it also have a toolbar with Encrypt and decrypt.
When encrypt is hit I want to take the data from mainForm PlainText textbox and encrypt it. Once encrypted send it back to the mainForms chiperText box.
If they hit decrypt it's the same thing just reversed.
By using this tutorial( I used the property way)
http://www.codeproject.com/KB/cs/pass_data_between_forms.aspx
I been able to send the PlainText data to the shiftChiper form and encrypt it. What I can't do is send the new encrypted data back to the ChiperText textbox in the mainForm.
So anyone know how to do this?
I simple example would be nice. It can be just 2 textboxes on one form and a button. when the button is clicked a form2 is made and it sends over one of the textboxes. One form2 it can have a button when clicked it sends the data that was sent back to form1.
I am doing it in C# by the way.

I think I know what you're talking about. let me see if I can help.
Anything in public access space on the popup can be accessed by the main form from wherever the instance of the popup is.
For example. on my main form named form1 I have a button that opens a popup named form2. in the button click event on form1's button I'd have something to the effect of
PopupFormTypenameGoesHere form2 = new PopupFormTypenameGoesHere( params to send et all)
form2.ShowDialogue();
Text = form2.someInfo;
and in form2's close event I'd have
someInfo = "hello world"; // or whatever
This would cause form1's title (ie it's Text property) to be set to "hello world" after the popup had closed (or whatever someInfo was set to in that form)
I hope that helps.
One thing you should be careful with is the usage of Show() and ShowDialogue() - they are NOT interchangeable.

do you need to use 2 forms? is there a critical reason? i don´t see it.
i use (1) parent form/child form method or (2) the form + userforms (loaded in form) method
but i don´t see how you can get it to work, i assume you did the same in both forms. i think it´s because the first owes the second. Are you using delegates?
check articles here on those methods, you won´t get errors  and look nicer

Envents and/or delegates are the answer.
I posted a delegate sample here[^] previously.

Hi,
I am trying to use DGVComboBoxColumn. I googled but didn't find any solution for below issue.
When I click on the DropDown it shows me DisplayMember i.e State name but after selecting one of them when I click somewhere outside, it displays ValueMember i.e Id of the state.
Please can anyone help me? Below is the code to load the State in DGVComboBox.
void LoadState()
{
try
{
dtState = GetState();
dgvCmbState.DataSource = dtState;
dgvCmbState.ValueMember = "Id";
dgvCmbState.DisplayMember = "sName";
}
catch (Exception ex)
{
}
}
Thanks

Hi there.
How can we find WindowState changes?
Is there an event for that ?
Thanks in advance.
|
|

Depends on what window state change notifications you need.
The Form class from the System.Windows.Forms namespace has some very common ones, like:
- Shown
- StyleChanged
- SizeChanged
- ResizeBegin
- ResizeEnd
- VisibleChanged
and some more. If you need to capture all changes, then you could derive your own Form from Form and handle the underlying WinAPI WM_ messages yourself.

On my windows form, upon clicking on a form i add a button where ever the mouse was clicked. But how
can i know if a "ESC" key is press so i cancel the add button on a form.
|

One quick solution would probably something like:
1) on first mouse click, create the button and set its type to something like "floating"
2) while floating, let the button follow the mouse cursor (mouse move event)
3a) if the user presses the mouse button again, then set the button to a fixed position on the form and remove the "floating" property
3b) if the user presses the escape key (KeyPress/KeyUp-event) while the new button is in "floating" mode, remove it from the list of controls entirely.

If you use punctiation when you write, it gets very much easier to understand what it is that you are trying to say.
To get the card value, you have to use the index of the card that you have picked. You have to store that value in a variable before using it to get the value from the card array, so that you can use it to get a value from the cardValues array also.
Despite everything, the person most likely to be fooling you next is yourself.

This is just wrong all over.
First off, selecting a random rank (string[] card) and a random suit (string[] cardSuits) to create a card is a bad idea. What if you pick the same card twice in one hand? How will you remove cards from a "deck" as they are dealt. You better rethink your object design.
Second, your cardvalues array is wrong. For example, let's say your random number for the card rank is "0" (which, by the way, you don't save anywhere). You have string card[0] == "Two " but int cardvalues[0] = 1. That's wrong.
I'm not saying this is the best design, but start with something like:
cardID = random.Next(0,52);
cardSuit = cardID / 13;
cardRank = cardID % 13;
blackjackValue = cardValues[cardRank];

The System.Web.UI.WebControls.Table class has a BorderStyle property, so that's obviously not the class that you created. Is that the class that you intended to create?
Is it a WPF project? Then you use BorderBrush and BorderThickness to specify the border.
Despite everything, the person most likely to be fooling you next is yourself.
