I have a button that when clicked, it populates a panel control with radio buttons and textBoxes controls.
Is there a simple way to reset (clear) the panel instead of removing each control at a time?

Windows uses Win32-API. Dx was introduced as an API for games and multimedia-appz in the middle of the 1990s.

DirectX is included in windows since Windows98. In windowsXP sp2 DirectX 9.0c and .NET 1.1 framework (in the english version, but not in the german  ) is included, so everyone should run your application.

Hi!
This may be a rookie question, but the truth is I can't do it: how do I use a C++ class in a C# project?
I have a C# project that works just fine, but I need to use a class implemented in a C++ project. I simply added the C++ project to my solution but I keep getting bulding errors. Is this the right thing to do?
|
|
|
|
|
Is your C++ class written in Managed C++? Only classes written in MC++ are accessible from C#.

Hello,
I'd like to know if its possible to repeat an image instead of streching it for a specified width/height (rectangle).
I tried to see if a DrawImage(...) method allowed me to do that, but to no result.
Thanks IA.

I'm working on a ASP.Net and C# project and want to send email through exchange server and
I only have a mailbox folder name (like "User 1") which exists on exchange server. If I send
email to "User 1" through my MS Outlook it works fine but I don't know how to obtain email
address of "User 1" from exchange server from my ASP.Net, C# application.
Can anyone post sample code or give some direction to resolve this issue.
Any help will be appreciated.

Give the Anchor property a value, In the side that you want it to be fit to.

Hi,
i need to work with an unmanaged dll and in each function i want to use i have a struct as parameter. The layout of this struct is given in a c header file, but i'm not sure how to get this working in c#  Here is apart of the struct:
<code>
struct _stEgControl
{
struct _stEgData *pstEgData;
wchar_t *pszCommName;
void *pvEgVideoBufferAddress;
void *hEyegaze;
}
</code>
Question 1:
this struct inside my struct is rededined by me in a class with the same way. I'm not sure if this i right:
<br />
[MarshalAs(UnmanagedType.LPStruct)]<br />
public _stEgData *pstEgData;<br />
Question 2:
there is no wide character in c#. can i use a char?
Question 3:
how i have to work with this void* ? How do i manage this in my class ?
could it be in this way:
<br />
[MarshalAs(UnmanagedType.FunctionPtr)]<br />
public void *pvEgVideoBufferAddress;<br />
Thanks for help.

Hi,
you have to install the Microsoft DirectX 9.0c SDK (the newest SDK is from october 2005: http://www.microsoft.com/downloads/details.aspx?FamilyId=1C8DC451-2DBE-4ECC-8C57-C52EEA50C20A&displaylang=en)
and Managed DirectX. Also, you have to put a reference to the dlls in your VS oder #d-project.

Hi there I've encountered a small problemo......
I'm trying to change brightness of an image...so far so good.
However I managed to make it work on 24-bit format images. When the filter is fed with an image which is either 8bit indexed or 32-bit formats...it fails!
...is there any way to access 8-bit indexed images with C# pointers!
I was observing this message board and found out the following code:
<br />
Bitmap bmp = new Bitmap(width, height, PixelFormat.Format32bppArgb);<br />
<br />
Graphics g = Graphics.FromImage(bmp);<br />
g.DrawImage(src, 0, 0, width, height);<br />
g.Dispose();<br />
...Many thanks to Andy Kirillov
Does the above code...'store' my image as a 24 bit image?
The code project....a perfect experience

Hello
Yes, you can use the above code to convert your image to 24bpp or 32bpp format (as you already know, Image.Clone does not produce this functionality, as it was expected). With 24bpp image you can use most of image processing filters.
XeoN-Kc wrote: I was observing this message board and found out the following code:
Yes, there is. Use LockBits. But, you will get troubles if you have color indexed image (like GIF). As you can see from my first article, I am using 24bpp format for color images, 8bpp indexed for grayscale images. Both formats I am processing using LockBits. And in the case of grayscale image it's rather obvious to implement brightness filter (the same logic as for 24bpp).

Hi all,
I’m developing a client/ multi-threaded server and I’m a little bit concerns about the following:
Although at the server program (in which I run a service that runs this program at the background) I’m releasing unnecessary resources once I finished from them, I found that as clients joins the application, the Task Manger indicate an incensement at the memory assigned to the server application. Any idea of how I could minimize these Memory consumption
Thanks in advance
Kind Regards,
Mohammad

guys,
Can someone give me an Idea or link on how to handle a header / detail in my web application..
Scenario: Once the user completed the header information (textboxes) he will fill up the detail it can be many and at the same time the detail screen is on another page. After filling up the first ROW I will press the ADD button to create a header/detail record but in this case I dont want to save it directly to my SQL server until all the details has been done. Then, I press the SUBMIT button.
Can I do it in session variable or should I save it first to XML file then upon pressing the submit button I will save it to database.
Thanks.
