If I understand correctly, what you want to know about is a window which hides automatically when the focus is moved away from it (for example certain windows in the IDE of Visual Studio .NET). If it is so, you may try to have a look at the source code here[^]), though you may have to go through tons of code.

No, I am attempting to paint a grid in the forms OnPaint function but can't find a way of painting on top of the child controls.

Hi,
I want to be able to view pdf files in Winforms. The easiest way I could think of was to create a webcontrol in my winforms. I knew you could very easely do this in C++, but in C# I didn't find such a control. Looking on MSDN and CP I found things like WebClient and WebControl classes, but I can't figure out how they work, in what control do you view the actual page?
So there would be two possible ways I could think of:
1: Create a WebControl
2: Embed I-Explorer into the application.
Can anyone give me any advise what would be best and to what I should look for?
tnx!
No hurries, no worries.
[EDIT]
I found it, off course it was easy enough  .
Choose add user control in the toolbox, under COM component choose Microsoft Web Control.
Add the webcontrol to your from.
That's it.

use axWebBrowser control, it is able to view pdf files and also other MS Office file, it is present on the left side panel,DATA panel or add it.
sample is like this
object empty = System.Reflection.Missing.Value;
webBroswerControl.Navigate("c:\\abc.pdg", ref empty, ref empty, ref empty, ref empty);
i hope it will help u

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 ?
