Do you just want to display some text in the top left corner (framerate)?.
The DirectX SDK has a common library included with it (under Samples/C#/Common) which has utilities to easily render text. The file you'll be after is D3DFont.cs. You can render text easily with 3 lines of code using the font class included in this.
If you want to know how to display the framerate take a look in the file D3DApp.cs (under the C# common files again), it has a method starting at line 1148 called "UpdateStats" which does what your looking for (if you can be bothered making sense of it).

Dear All,
I have a VB6 Application which throws events. How can I capture these events in my another C#.Net Application?
Please help me providing articles or links.
Thanks in advance.

What kind of events does VB6 application throw? Can you give us the example?

Like Michael said, how is the VB6 event being thrown. Without knowing, we can't really help.

I figure I either made them feel really stupid or answered their inquiry.

function readtext reads a myfile.txt and i want invoke this method to mail.Body. by send mail event.
private static void readtext()
{
FileStream fs = new FileStream("C:\\myfile.txt", FileMode.Open, FileAccess.Read);
StreamReader sr = new StreamReader(fs);
sw.BaseStream.Seek(0, SeekOrigin.Begin);
string str = sw.ReadLine();
while (str != null)
{
str = sr.ReadLine();
}
sr.Close();
fs.Close();
}
}
thanks!
so much of happy ending...

 Rephrase it, you aren't making much sense.

Look into System.Net.Mail (specifically the MailMessage and SmtpClient classes) to send the emails. Also, your method should return the string it is building. Perhaps you should do something like the following (be careful if the file can be large, as it may throw a memory overflow exception)...
private static string ReadText(string fullFilePath) {
FileStream fs = null;
StreamReader sr = null;
try {
fs = new FileStream(fullFilePath, FileMode.Open, FileAccess.Read);
sr = new StreamReader(fs);
return sr.ReadToEnd();
} finally {
if (sr != null)
sr.Close();
if (fs != null)
fs.Close();
}
}Alternatively, you could send the file as an attachment. Examples of this can be found when you examine the MailMessage class. Hope this helps,
Sounds like somebody's got a case of the Mondays

Hi,
I'm having trouble in transferring arrays of short integers from C++ library to C# application.
I got the sources of a library, written in C++, that defines interface in IDL file.
The original methods transfer "basic" objects, such as BOOL and BSTR.
I need to add a new method to the interface for transferring two arrays of short integers.
For that purpose, I create two safe arrays and populate them with the numbers.
However, when I try to invoke the C# method I get TypeMismatch error code (when I pass only the string objects, it works OK).
The C++ code includes the following definition in IDL file:
library CodecLib
{
...
dispinterface _ILiveEvents
{
properties:
methods:
...
[id(4), helpstring("method DataReady")] HRESULT DataReady([in] BSTR strForward, [in] SAFEARRAY(short) FwdBuffer,
[in] BSTR strReturn, [in] SAFEARRAY(short) RetBuffer);
};
...
};
The following C# code implements the interface defined in the IDL file:
private void DataReady(string sForward, Array ForwardData,
string sRetrun, Array ReturnData)
{
...
}
The following C++ code prepares the data in the safe arrays:
void CLive::DataReady(short *pFwdBuf, short *pRetBuf, int nBufferSize)
{
long lIndex;
SAFEARRAYBOUND ArrayBound[2];
ArrayBound[0].cElements = nBufferSize;
ArrayBound[0].lLbound = 0;
ArrayBound[1].cElements = nBufferSize;
ArrayBound[1].lLbound = 0;
m_pFwdBuffer = SafeArrayCreate(VT_I2, 1, &ArrayBound[0]);
m_pRetBuffer = SafeArrayCreate(VT_I2, 1, &ArrayBound[1]);
// Set data in safe arrays
for (lIndex=0; lIndex<nBufferSize; lIndex++)
{
SafeArrayPutElement(m_pFwdBuffer, &lIndex, &pFwdBuf[lIndex]);
SafeArrayPutElement(m_pRetBuffer, &lIndex, &pRetBuf[lIndex]);
}
// Send data to clients
Fire_DataReady(m_strForward, m_pFwdBuffer, m_strReturn, m_pRetBuffer);
// Release safe arrays
SafeArrayDestroy(m_pFwdBuffer);
SafeArrayDestroy(m_pRetBuffer);
m_pFwdBuffer = NULL;
m_pRetBuffer = NULL;
}
The following C++ code distributes the data to the clients.
However, calling Invoke() returns TypeMismatch error, with uArgErr equals to 3:
HRESULT Fire_DataReady(BSTR strForward, SAFEARRAY *pFwdBuf,
BSTR strReturn, SAFEARRAY *pRetBuf)
{
HRESULT hr = S_OK;
T * pThis = static_cast<T *>(this);
int cConnections = m_vec.GetSize();
for (int iConnection = 0; iConnection < cConnections; iConnection++)
{
pThis->Lock();
CComPtr<IUnknown> punkConnection = m_vec.GetAt(iConnection);
pThis->Unlock();
IDispatch * pConnection = static_cast<IDispatch *>(punkConnection.p);
if (pConnection)
{
CComVariant avarParams[4];
avarParams[0] = strForward;
avarParams[0].vt = VT_BSTR;
avarParams[1] = pFwdBuf;
avarParams[1].vt = VT_ARRAY;
avarParams[2] = strReturn;
avarParams[2].vt = VT_BSTR;
avarParams[3] = pRetBuf;
avarParams[3].vt = VT_ARRAY;
CComVariant varResult;
unsigned int uArgErr;
DISPPARAMS params = { avarParams, NULL, 4, 0 };
hr = pConnection->Invoke(4, IID_NULL, LOCALE_USER_DEFAULT, DISPATCH_METHOD, ¶ms, &varResult, NULL, &uArgErr);
}
}
return hr;
}

Good day everyone,
I have a problem that I really need someone help.
I have an array of objects that is filled from the content of a text file. One line in ther text file contains name,address and employeeID.
The problem is that I can not compare the employeeID in the object with a given employeeID.
How can I get the value of employeeID out of the the array of objects?
Please help.Thanks much in advance
Employee[] employeeList = new Employee[100];
employeeList = new Employee[100];
EmpFileReader empfile = new EmpFileReader();
employeeList = empfile.readFile();
//getEmployeeID returns ID
if(employeeList[i].getEmployeeID()== employeeID )
System.out.println(employeeList[i]);

First thing you need to do is that you have to ensure whether readFile() method can parse the value from text file to the employee object.
Once you are sure about readFile(), you can just loop through the array and compare the ID..

employeeList = new Employee[100];
No need to instantiate the array twice. btw.

Hi Michael,
I'm sure that the array of object has all data pulled from the text file.
I can get the value of employeeID from the array of object, but when I compare with a given string, then it does not work.
for (int i=0; i<noemployees; i++)<br="" mode="hold"> {
if(employeeList[i].getEmployeeID()== "1234" )
System.out.println(employeeList[i]);
}

Try to write all id of employees array.. see whether you got all employee ids (including the one that you want to search) or not..
For each(Employee emp in Employees){<br />
Console.WriteLine(emp.ID.ToString());<br />
}<br />
<br />

hi,
i did a Dll which i use on HTML page.
namespace Control {
public interface myIn
{
}
public partial class UserControl1 : UserControl, myIn
{
public UserControl1() {
InitializeComponent();
}
}
i want to write to a file on the client's computer:
private void button2_Click(object sender, EventArgs e)
{
StreamWriter f = new StreamWriter(@"c:\\myfile.txt", false);
f.WriteLine("test");
f.Flush();
f.Close();
}
when i click this button i get an error message in the browser indicating that an unpremessioned taks took place - and the file is not written.
does anybody know how to write to the clients computer (via this COM object)?
thanks,
Samy

It's not allowed to do that for security reason unless the client has added your site in trusted website..

Hello,
I think your code will going to write the file on the Server. but It is not permitted. Actually this is Server side code. You may test this on other computer(cliant) on LAN, I think it will write on the server where it is reside.
This is the Suggestion. Please reply after test or found solution.
Best of Luck.

it is in Javascript - so it is in the client's computer not the Server side.
