Hello dear buddies,
I have read System.Reflection types that help to dynamically invoke object members are slow and are not suitable for high-performance applications.
My question:
Is the low speed because of the member search that is performed to find the requested member to get respectful 'MemberInfo' object (to invoke it) OR not only the member name search but also the member invokation using 'MemberInfo' object is a slow process itself?
A comparision between speed of direct method call and dynamic method call using 'MethodInfo.Invoke()' really helps me to find my answer too.
Thank you so much for any help and note

That's a really generic question and way to large to be answered in the forums.
It doesn't sound like you have enough experience in the MANY different fields your going to need to accomplish this. I'd suggest picking up books having to do with DirectX, 3D modeling, and animation.

There are .NET equivalents you can use for the "dir" command. See System.IO.Directory/DirectoryInfo and System.IO.File/FileInfo.
That still doesn't answer your question though; this works for me with a cmd window:
System.Diagnostics.ProcessStartInfo psi = new System.Diagnostics.ProcessStartInfo("cmd");
psi.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
System.Diagnostics.Process.Start( psi );

anyone out there know how to set a C# windows forms application to expire, say, after 3 months?
i'd really appreciated if you could point me in the right direction in trying to find out, thanks!
|
|
|
|

The easiest thing to do would be to put this into the constructor of the form:
if( (DateTime.Now - DateTime.Parse("20 February, 2005")).Months >= 3 )
{
throw new Exception("This application has expired");
}
Extending on that just a bit though you can use the License mechanism built into the framework.
[LicenseProvider(typeof(MyLicenseProvider))]
public MyForm : Form
{
License license = null;
public MyForm()
{
try
{
license = LicenseManager.Validate( typeof( MyForm ), this );
}
catch( LicenseException )
{
}
}
}Then code up your own MyLicenseProvider (using the base LicenseProvider class) to somehow know whether it has been 3 months.
All of this could be defeated with some work, but there are tools to help you combat that (Obfuscators, placing some important work along with the licensing procedure in native code).
The best way to stop it is to use a web service or remoting to do some important work and at the same time you can check whether the application has a valid license. This isn't appropriate for most applications though.

Hi,
I am Serializing an Object by using XmlSerializer but when XML file is created it is including the Namespace details like xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" in the Element.
But I dont want that Namespace details in the XML file.
Is there any way to do this.
Thanks for your help in advance.

i'm trying to make programme bout matrix,i have square matrix 4*4, please tell me how to choose first column and second row ([1][2]) of the matrix
pleeeaaaseee help me
thank you
|

Try using a multi-dimensional array. For example, for a 4*4 matrix of integers, use the following 2-dimensional array:
int [ , ] myMatrix = new int [4, 4];
To access a particular element of the matrix (say the first row and second column of the matrix, which is the 0,1 element on the 0-based array), do as under:
myMatrix[0, 1] = 5;
int i = myMatrix[0, 1];

Hi,
Is it possible to open a form in Modal mode to a Form which is Child to another Form.
I have 3 Forms - AppWindow, ChildWindow and DialogWindow. OnClicking a button in the AppWindow(Application), a ChildWindow is shown with AppWindow as its owner. again a DialogWindow is opened from the ChildWindow Form by using ShowDialog method. Now I need this DialogWindow to be Modal only to the ChildWindow which initialized it and not to AppWindow or any other ChildWindow's.
Can anyone tell me how it is done.
Please excuse my english
Thanks & Regards
Thejus

A modal dialog is likely to be modal to the application. Perhaps you can simulate modal behaviour for the one form, by keeping the DialogWindow as a variable, and checking if it's visible before accepting any input ?

Just like Christian suggested, but try disabling the ChildWindow when the DialogWindow is displayed. There's nothing in Windows or .NET that will allow the behaviour you want, you'll have to simulate it.
Actually modal dialog boxes work by disabling the parent window, and then executing another message loop (that's why the call to ShowDialog blocks.)
I would suggest changing your approach, because the problem is that there is only one message loop for the entire application, so, to achieve what you want, you'd need to display the form as modeless, and disable the ChildWindow so it doesn't accept any input while the DialogWindow is displayed. That might work, but still I don't know how intuitive that would be to your users, since I don't remember any other application in Windows working that way.

I agree with you. ShowDialog blocks the messageloop until processing of the dialog is complete. but, the ShowDialog method also has a parameter overload to set the parent, cant this be of any help to achieve the behaviour.
If not can you please suggest me how I could simulate the behavior.
Thanks & Regards

It's not the parent, but the owner, and it's not exactly the same thing.

Both Christian and I suggested already: disable ChildWindow or set a flag, and don't react to input if the DialogWindow is visible.

Hello,
I have my Toolbar control in my base MDI child form. Autosize is true, ButtonSize is 22,22 and Wrappable is false. And in every deriverd form it appears fine.
But I have one rebel form that has a ToolbarButton with style set to DropDownButton (an arrow to the right with a drop down menu.) In this form, the Toolbar is about 6 pixels taller, and no matter what I change, I can't make it the same size as the others (or the others taller.) If I remove the drop down button, everything comes out fine.
In the designer, with drop down button, the toolbar looks the regular height, but once I run the app, it appears taller.
I'm using XP styles.
Has anyone had this problem? any ideas?
-- LuisR
P.S. BTW, in IE there are both types of buttons - the CP toolbar has taller buttons for a 16x16 image, while the Google toolbar has regular-height buttons for the same 16x16 image.

I wonder whether the following would explain the reason (at least partially):
I tried to dig inside the disassembler for the System.Windows.Forms.dll file with ildasm. Also tried through a simple project. I started with a button size of 22,22. After clicking on the buttons collection property, in the ToolBarButton Collection Editor, what one notices is that the non-editable value of the Rectangle property for the first button is 0,0,23,22 (meaning that the size is 23,22) if the Style property is "PushButton". However, the moment one chooses the Style property as "DropDownButton", the said Rectangle property immediately becomes 0,0,36,22 (meaning that the size property is 36,22). Thus, a change of Style from PushButton to DropDownButton change the Height of Button from 23 to 36. It appears to be a read-only internal setting, though I am not very sure. I wonder whether this is a partial explanation.
After a slightly deeper research in the disassembler of toolbar class in the said dll file, for example, one notices that in the ToolBar::get_ButtonSize method, the button size is automatically set to either 39,36 or 23,22 depending upon the "Underneath" or "Right" values (respectively) of the TextAlign property of the button. Apparently, something similar is taking place in the internal coding of the said class when the Style property is being changed. Though, I must admit that I could not reach at the proper code after my limited research in the disassembled class structure. Perhaps some more study will reveal the secret of this behaviour.
I really do not know of what help, if at all, the above discussion would be to you...!

Just as I was finishing the reply, there was a power failure and I lost it all! 
So, here's again in a more summarized way:
I also looked at the dissasembly using .NET Reflector, and indeed found the same you did: that the ToolBar.ButtonSize property always returns a fixed size, depending on TextAlign. And neither I could find where the height is changed for a DropDownButton.
Sometime ago I asked here about setting the width of the buttons to be just enough for the text, and not always the same. Looking at the disassembly, there's a ToolBar.ForceButtonWidths internal method that doesn't let the user do that. But also, each ToolBarButton has a Width internal property that returns the calculated minimum width for the button.
This article[^] in MSDN says that all the toolbar buttons must be the same size, but there's the TB_SETBUTTONWIDTH[^] message which lets you set the minimum and maximum width of a button.
Additionaly, the TB_SETUBUTTONINFO[^] message appears to let you set the width through the cx field of the TBBUTTONINFO strucrure (which the .NET ToolBar control uses extensively.) But there's nothing to set the height (maybe TB_SETBUTTONSIZE before adding any buttons could work).
Well, I guess this would make for a great CP article. I'll look into it when I have some free time. For now I should better get back to work.
Thanks for your time!

Hello,
I am trying to find a faster, better way to know when something on the desktop changes. Could be application focus, text being typed, time in the systems tray changes..anything.
Instead of using a screenshot and figuring out the difference. Isnt there a way to tap into the desktop update events? Kinda like you hook into the mouse and keyboard events?
I know there are some custom video drivers out there that vnc uses. But I dont think thats something that can be used in C# affectivly.
Any suggestions or comments?
thanks
Steve
