I have the following code to create an xml file, that is returned by a web service

<br />
XmlDocument doc = new XmlDocument();<br />
doc.LoadXml(xml);<br />

the xml vairable is a raw sting with xml in it

I would like to add the headers for the XLST file and DTD

I've not been able to find any code examples for this. Atm the web service just returns the xml which is fine, but I can't work out how to get it to put the headers in that will point to the .xsl file.

Anyone know how to do this?

Is it possible to acquire .NET form object properties from another application?

As a software tester, I'm assigned a task to log UI loading times of a very large application, which is written in C#/.NET Framework. I really don't want to do this manually whereby I use a stopwatch and my slow fingers to record the loading times. So I thought of writing a macro-based program that can approximate the location of certain form elements.

Is it possible to write a C# application that can retrieve .NET form object properties from a parent application WITHOUT having to modify the parent application's code? Maybe something like COM (don't know too much about it) could help me out?

This article uses PowerShell to test UI on a web app, maybe you can use the same technique

That's an interesting technique, Mark. Do you think the same can be applied to Windows binaries which use .NET?

Thanks.

Hi...,

I've added to my code the following MouseWheel event to a Forms panel.

this.panel1.MouseWheel += new System.Windows.Forms.MouseEventHandler(this.panel1_MouseWheel);

This is the event:

private void panel1_MouseWheel(object sender, MouseEventArgs e)<br />
{<br />
 MessageBox.Show("MouseWheel event now activated", "MouseWheel", MessageBoxButtons.OK, MessageBoxIcon.Information);<br />
}

When I rotate the mouse wheel nothing happens. What I am doing wrong?

Thank you,

Michael

Hi,

a Control such as your Panel will react to keyboard and mouse events only
when it has focus. Has your Panel focus? Click inside it (but not inside one
of its internal Controls assuming you added some).

How do i write a C# application in Visual Studio 2005 that scans for Bluetooth devices ?

Hi,

I have tried out several samples for scanning bluetooth devices from a c# application but notting seems to work for me.
I keep getting build errors.

Can someone mail or post me a working sample/vs project ?

thanks a lot in advance for your help.

Gareth,

1. I only found a way to use bluetooth by c++ , not c#
So i tryed to write a dll in c++ and use those functions in c#

Example :
// bluetoothdll.h
namespace bluetooth
{
class Bluetoothclass
{
public:
static __declspec(dllexport) void WINAPI Scan(LPVOID lpParameter);
};
}

// bluetoothdll.cpp
#include <bthsdpdef.h>;
#include <bluetoothapis.h>;
#pragma comment ( lib, "Irprops.lib")

#include "bluetoothdll.h"

#define MAX_DEVICE_COUNT 32 // just assumption
BLUETOOTH_DEVICE_INFO device_array[MAX_DEVICE_COUNT] ;
static int device_array_pointer = 0 ; // my cursor variable

namespace Bluetooth
{
void WINAPI BluetoothClass::Scan (LPVOID lpParameter)
{
** my code **
}
}

this wont build : 199 errors in the upper two headerfiles

so i didn't got to the c# part , but i would have wrote it like this :

[DllImport("Bluetoothdll.dll")]
static extern void WINAPI Scan(LPVOID lpParameter);

2. i wanted to make it easyer by writing it all in c++
first i tested this sample i got from internet :

#include <winsock2.h>
#include <ws2bth.h>
#include <bluetoothapis.h>
#include <stdlib.h>
#include <stdio.h>
#include <iostream>

#pragma comment(lib, "ws2_32.lib")
#pragma comment(lib, "irprops.lib")

using namespace std;

int main(){
//Initialising winsock
WSADATA data;
int result;
result = WSAStartup(MAKEWORD(2, 2), &data);//initializing winsock
if (result!=0){
cout << "An error occured while initialising winsock, closing....";
exit(result);
}

//Initialising query for device
WSAQUERYSET queryset;
memset(&queryset, 0, sizeof(WSAQUERYSET));
queryset.dwSize = sizeof(WSAQUERYSET);
queryset.dwNameSpace = NS_BTH;

HANDLE hLookup;
result = WSALookupServiceBegin(&queryset, LUP_CONTAINERS, &hLookup);
if (result!=0){
cout << "An error occured while initialising look for devices, closing....";
exit(result);
}

//Initialisation succedd, start looking for devices
BYTE buffer[4096];
memset(buffer, 0, sizeof(buffer));
DWORD bufferLength = sizeof(buffer);
WSAQUERYSET *pResults = (WSAQUERYSET*)&buffer;
while (result==0){
result = WSALookupServiceNext(hLookup, LUP_RETURN_NAME | LUP_CONTAINERS | LUP_RETURN_ADDR | LUP_FLUSHCACHE | LUP_RETURN_TYPE | LUP_RETURN_BLOB | LUP_RES_SERVICE,&bufferLength, pResults);
if(result==0){// A device found
//print the name of the device
LPTSTR s = pResults->lpszServiceInstanceName;
wcout << s << "found. quering for services\n";
//Initialise quering the device services
WSAQUERYSET queryset2;
memset(&queryset2, 0, sizeof(queryset2));
queryset2.dwSize = sizeof(queryset2);
queryset2.dwNameSpace = NS_BTH;
queryset2.dwNumberOfCsAddrs = 0;
CSADDR_INFO * addr = (CSADDR_INFO *)pResults->lpcsaBuffer;
WCHAR addressAsString[1000];
DWORD addressSize = sizeof(addressAsString);
WSAAddressToString(addr->RemoteAddr.lpSockaddr,addr->RemoteAddr.iSockaddrLength,NULL,addressAsString, &addressSize);
queryset2.lpszContext = addressAsString;
GUID protocol = L2CAP_PROTOCOL_UUID;
queryset2.lpServiceClassId = &protocol;
HANDLE hLookup2;
int result2 = WSALookupServiceBegin(&queryset2, LUP_FLUSHCACHE |LUP_RETURN_NAME | LUP_RETURN_TYPE | LUP_RETURN_ADDR | LUP_RETURN_BLOB | LUP_RETURN_COMMENT, &hLookup2);
if (result2 !=0){
cout << "An error occured while initializing query for services";
exit(result);
}

//Start quering for device services
while(result2 ==0){
BYTE buffer2[4096];
memset(buffer2, 0, sizeof(buffer2));
DWORD bufferLength2 = sizeof(buffer2);
WSAQUERYSET *pResults2 = (WSAQUERYSET*)&buffer2;
result2 = WSALookupServiceNext(hLookup2,LUP_FLUSHCACHE |LUP_RETURN_NAME | LUP_RETURN_TYPE | LUP_RETURN_ADDR | LUP_RETURN_BLOB | LUP_RETURN_COMMENT,&bufferLength2,pResults2);
if(result2 == 0)
wcout << "Service found: " << pResults2->lpszServiceInstanceName <<"\n";

}
}
}
return 0;
}

But i also get lots of errors :

Hi to all,

Anyone know how to use a LinkLabel into a ListView? I want to use the LinkLabel to send email, so when I click on it the default email client will start up (fire up the email client isn't a problem)...if anyone has already done it or know how to do it please post here.

Eventually, another method will be good.

Thanks.

Best regards.

This is a pretty vague question and out of scope for a programming forum. I suggest you buy some books. Amazon will have plenty of recommendations for advanced C# and/or ASP.NET AJAX.

I think the best way to start would be a GOOD BOOK on .NET. If you understand the framework then you won't have much problem learning any Visual Studio Language. And other thing, Practice, Practice, Practice and Practice. Just try different tools available in VS and make use of it.

Other source will be the 101 examples. They are really good, it helped me a lot moving on to .NET from VB6.

Hi everyone
We have many .doc files in an Ethernet,and many users are editing these,
we need a system version control over them which lets the progress get done concurrently
so anyone suggests any idea or experience ,I'll be thankful.

I don't know how to make collisions work for a game I'm currently making. I have an image (800 / 600) and a person. I'm not going to make any tile classes for the level (at least yet...), but I can't seem to get the person to 'work' with this. They fall through places and such, and sometimes when there's cliff, move straight to the top of it when moved that direction.

I have a physics engine I could utilize, but I heard it isn't great for platformers.
(To help understand my issue, I want something along the lines of the game "Braid")

If anyone could give *** *** *** ANY *** *** *** insight or help, please do. Even if it's a different design idea (such as tiles). (And please don't bring XNA's Torque level building whatever into this)

I hope I explained my issue well, but if there are any questions about the dilemma, please ask.

PLEASE help if you can. Thanks many in advance.
