Hey, I got a project to make an video application (that I can see myself on windows form). The problem is that I dont know how to do that kind of things, so I searched the net and found the WIA COM and thinking of using it. I found that article: WIA Scripting and .NET[^] But for some reason my computter says that the COM "WIALib" not exists... so I continued search and found that: http://www.codeguru.com/forum/showthread.php?t=439027[^] But for some reason, the line
CommonDialogClass class1 = new CommonDialogClass();
Gives me an problem
Error 2 Interop type 'WIA.CommonDialogClass' cannot be embedded. Use the applicable interface instead. C:\Users\Yahav\Documents\Visual Studio 2010\Projects\ControlCamera\ControlCamera\Form1.cs 69 40 ControlCamera
and the same for that:
DeviceManager manager = new DeviceManagerClass();
Someone can explain me why? Thank you very very moch! Yahav.

You can use ADO.NET to create database for the website, and then connect to it with the C# application. or you can do someting that call "web service" - open new ASP.NET Web service in your Visual Stduio, there, you can define methods that after you can call to then with your C#. after you finish define, go to the C# project, and then on the solution explorer->referance of the project click left mouse, click "Web referance", and look for your web service address, then you can use all the methods you defined.

So there is no other way to "say" to C# - "I want that control (for example button) to resize automatic"?

Hey, When I programed a new software in C# with Windows Form I got an "unsolved" problem that I hope you can help me with: I written a form, when I resizing it the form get bigger but the controls still the same. I wanted to know if there is a .NET built in command that can solve that probem? or i have to use the "Resize" event and set it myself?. And if yes - when i get the Resize event, can i know what is the last size before the resize and now? (like when i get the EventArgs e can i do someting like e.LastX or e.LastY)? Thanks you very moch!, Yahav.

Sorry about the hebrew... :$ Isolved the problem i enterd in the windows form into app.config and them edit
<setting name="WindowsUniversityClient_UniversityWebReference_Service"
serializeAs="String">
<value>http://192.168.111.1/UniversityWebServices/Service.asmx</value>
</setting>
To:
<setting name="WindowsUniversityClient_UniversityWebReference_Service"
serializeAs="String">
<value>http://192.168.111.1/UniversityWebServices/Service.asmx?AspxAutoDetectCookieSupport=1</value>
</setting>
Now, when he hav AspxAutoDectateCoolieSupport it gives me the results :D Thanks for your help!, Yahav.

Hey, i hope you can help me with my question: I started learning working with DirectX, in the start i saw a codeexample for how open an empty window (without chosing winn app at the start of Visual Studio) but for some reson, the code makes me problems, hope you can say to me why code
#include <windows.h>
HINSTANCE hInst; // global handle to hold the application instance
HWND wndHandle; // global variable to hold the window handle
// forward declarations
bool initWindow( HINSTANCE hInstance );
LRESULT CALLBACK WndProc( HWND, UINT, WPARAM, LPARAM );
int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow )
{
// Initialize the window
if ( !initWindow( hInstance ) )
{
return false;
}
// main message loop:
MSG msg;
ZeroMemory( &msg, sizeof( msg ) );
while( msg.message!=WM\_QUIT )
{
// Check the message queue
while (GetMessage(&msg, wndHandle, 0, 0) )
{
TranslateMessage( &msg );
DispatchMessage( &msg );
}
}
return (int) msg.wParam;
}
bool initWindow( HINSTANCE hInstance )
{
WNDCLASSEX wcex;

Hey, I want to ask for your help: i am in the middle of building a program using C#, the program have to read XML file from the net that including the information about the member that logind in (this is a website) and display it in the program. the problem is that when i do the requst it not send any cookies with the requst, so the xml return guest, how can i get with C# the cookies that was sendin the website to send them? example: i have loggind in the website with "gindi bar yahav", "123321" - the web set cookies on my computer, now i want to get those cookies with C# becuse i need to use them when i requst from the XML file. that was the code i used
try
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(this.xml\_file);
request.Method = "GET";
// Fetch cookies
CookieContainer web\_cookies = new CookieContainer();
CookieContainer cookies = web\_cookies.GetCookies(new Uri("http://otaku-con.co.il"));
request.CookieContainer = cookies;
// Send
HttpWebResponse resp = (HttpWebResponse) request.GetResponse();
st = resp.GetResponseStream();
sr = new System.IO.StreamReader(st);
// read all the text in it
System.Windows.Forms.MessageBox.Show(sr.ReadToEnd().ToString());
}
catch(Exception e)
{
System.Windows.Forms.MessageBox.Show(e.ToString());
System.Windows.Forms.Application.Exit();
}
when i get the message it gave me "Array()" what means i dont have any cookies (in the page i tried only to print the cookies [with PHP]) but when i go to the page with the browser i can see all my cookies. someone know what the problem? thanks alot, Yahav.

({my home address} = my home ip address) but when i entering localhost (mean my own mysql server that i have insalled on my computer) its works very well someone can explain me why i get this error, and how can i connect to remote server, if this is a problem with my website host, do you have a hosts that give me the abillty to do that? thanks you very motch, Yahav.
