With controls unless you're deriving your own you should not manually dispose resources. If you read the documentation for the Form.ShowDialog method, you should notice that you do need to dispose the form in order to dispose of its message pump. An easy way - even in case of an exception - use the using block statement:
using (MyForm form = new MyForm())
{
form.ShowDialog();
}If you don't dispose your object - which will dispose all its child objects that it knows about - when you use a modal dialog (using ShwDialog), the unmanaged memory will not be released (which is why it's called unmanaged resources).
If you're having problems with threads, make sure that you're only updating controls (like setting the Text property or adding a ListViewItem to a ListView) on the thread on which the control was created. See the InvokeRequired property and the Invoke method documentation in the .NET Framework SDK for more information and examples aobut how to use them.

Hi all,
I would like to program the following in Internet Explorer
by C# : add a menu item in the context menu when right click a selected text section in IE and perform some action when the menu item is selected. And how about the similar stuff for right clicking the image in IE ?
Is it related to the shell programming also ?

I answered a very similar question just the other day. You should make it a habbit of searching first. To search the forums on this site, you click "Search comments" at the top of the message board on each forum (which also lets you search additional forums at the same time).
Take a look at http://www.codeproject.com/script/comments/forums.asp?msg=943726&forumid=1649#xx943726xx[^], which includes other links to MSDN for more information.
As I mention in that thread, I recommend you don't use managed code for this as it adds a lot of overhead to the iexplore.exe (or whatever process hosts the WebBrowser control) in terms of memory and other system resources.
There's also articles here on CodeProject about writing WebBrowser extensions, both in unmanaged and managed code. Enter your search in the text box directly below the logo at the top of each page.

If you have questions about specific products you should first ask the authors of that product. See http://www.syncml.com[^], which has a link at the top of the page, Contact OMA[^].

I would like to use DPAPI - Data Protection Application Programming Interface to write a Pocket PC application. But does .NET CF have DPAPI?
If not (so unlucky), what can I use?
Thx
|
|
|
|

The .NET Framework doesn't encapsulate DPAPI at all. You have to P/Invoke the necessary calls yourself. Read How To Create a DPAPI Library[^].
The Data Protection APIs are supported under Windows CE .NET 4.2 (PocketPC 2003). Windows CE 3.0 does not the DPAPI APIs documented and probably doesn't support it.
Even on PocketPC 2003 (which is actually named "Windows Mobile for PocketPC 2003") you may run into problems because not all of the System.Runtime.InteropServices namespace members are supported. Be sure to view the supported platforms while reading through the System.Runtime.InteropServices documentation in the .NET Framework SDK.

Hi,
I need to print in Windows98 using Star printer - SP200, which is not capable of graphical printing (can't use DrawString()).
I've tried the code in
<www.c-sharpcorner.com code="" 2002="" oct="" printdirect.aspect.asp="">
changed the left margin (the paper width is 3 inches only) and the ip of printer to be the default printer name using <printersettings.printername> (not shared)
the result is the handle lhPrinter=0 and no response from the printer; nothing is written (pcWritten = 0) although the result of OpenPrinter is not 0.
I appreciate your help...

Hi,
I want to print a report. The height of the report is dynamic.
When I print the report, after the end job, printer eject the last page more than I need. LQ300 eject paper as long az A4 size.
for example: I want to print one line, then the printer stop printing. If I need the paper I self cut it & use it.
I use a roll of paper, no A4 or A3.
I am using c#.
what must I do?
Thanks & Best regards

Permission objects are used by the Framework to protect users and machines and may be instantiated to authorize certain operations. Depending on how certain permissions objects are used, they may remain ni memory until the AppDomain is shutdown.
You should read about Code Access Security - an integral part of the .NET Framework - on MSDN. Read Code Access Security[^] in the .NET Framework SDK.

1. Why are you posting registration problems to another site here? Why not try to contact the owner of the site your having problems with?
2. Nice of you to post your account name and password for us to use! Like Colin asked... What the hell are you smoking?!

I've put together a component that, upon a certain action, a window opens. I am opening that window directly below the component, aligned with the bottom edge. It works great and exactly as I need it to...until the UC form is contained within a mdicontainer.
I am currently determining the position to place the window by looking at the position of the current component and its parents. Apparently with mdicontainers, the child form is a parent and I cannot get the appropriate screen position because the application form creates an unknown offset.
private void GetRefLocation(Control controlIn, ref int top, ref int left)<br />
{<br />
<br />
Control controlParent = controlIn.Parent;<br />
Form parent = this.FindForm();<br />
<br />
if (parent == controlParent)<br />
{<br />
top += parent.Top;<br />
left += parent.Left;<br />
}<br />
else<br />
{<br />
int addHeight = 0;<br />
System.Type a = controlParent.GetType();<br />
string b = controlParent.GetType().FullName;<br />
if (controlParent.GetType().FullName == "System.Windows.Forms.Panel")<br />
addHeight = ((Panel)controlParent).BorderStyle == BorderStyle.None ? 0 : (((Panel)controlParent).BorderStyle == BorderStyle.FixedSingle ? 1 : 2);<br />
<br />
top += controlParent.Top + addHeight;<br />
left += controlParent.Left;<br />
GetRefLocation(controlParent, ref top, ref left);<br />
}<br />
}
What do I really need to do to determine the position within the screen? I followed a couple trails involving GDI but I never found a way that I can set component.Location based on the screen position, let alone position of another component.
Thanks

Use the PointToScreen and PointToClient methods of Control class to convert a location from client coordinates to screen coordinates respectively the other way round.
