hi all,
I have created a DialogBase Application using MFC ,Visual C++..
Now I want to create Web Interface to my Application..How am I going to do that ?..
If any one know that please reply me..
Thanks in advance..

If it's a dialog application just use the ActiveX web browser control.
How do I print my voice mail?

Your question is a little confused.
Are you wanting to create a web interface that runs on a web-server and users access via a browser? Or do you want to emulate the web-look and feel like Microsoft Money attempts to.
If you want to run your app off a web-server, then you'll need to look into one of the web technologies such as ASP.NET or PHP or ASP.

Does anyone know if it is possible to cast a GDIPlus *Image to a GDIPlus Bitmap? I can't seem to figure this one out.

i have serial class library.
i use read data function.
this is following.
//Serial.cpp
////////////////////////
int CSerial::ReadData( void *buffer, int limit )
{
if( !m_bOpened || m_hIDComDev == NULL ) return( 0 );
BOOL bReadStatus;
DWORD dwBytesRead, dwErrorFlags;
COMSTAT ComStat;
ClearCommError( m_hIDComDev, &dwErrorFlags, &ComStat );
if( !ComStat.cbInQue ) return( 0 );
dwBytesRead = (DWORD) ComStat.cbInQue;
if( limit < (int) dwBytesRead ) dwBytesRead = (DWORD) limit;
bReadStatus = ReadFile( m_hIDComDev, buffer, dwBytesRead, &dwBytesRead, &m_OverlappedRead );
if( !bReadStatus )
{
if( GetLastError() == ERROR_IO_PENDING )
{
WaitForSingleObject( m_OverlappedRead.hEvent, 2000 );
return( (int) dwBytesRead );
}
return( 0 );
}
return( (int) dwBytesRead );
}
//testdlg.cpp
////////////////////////////
char lpBuffer[500];
int nBytesRead = serial.ReadData(lpBuffer, 500);
m_receivebyte=nBytesRead;
CString m_strreceive;
m_strreceive.Format("%d",nBytesRead);
if (m_receivebyte!=0)
{
AfxMessageBox("Receive Data "+m_strreceive);
}
/////////////////////////////
i want to know how to get string data from comport.
(for example - please enter string)
now,i receive only int data
(for example - 123)
please answer my application problems..

How about showing your string, lpBuffer, instead of the character size of lpBuffer?
char lpBuffer[500];
int nBytesRead = serial.ReadData(lpBuffer, 500);
m_receivebyte=nBytesRead;
CString m_strreceive;
<code>
</code>
if (m_receivebyte!=0)
{
<code>
lpBuffer[m_receivebyte] = '\0';
m_strreceive = lpBuffer;
</code>
AfxMessageBox("Receive Data "+m_strreceive);
}

Initializing an Array in a managed class viru_lent 19:47 1 Nov '04
Greetings everyone. I'm just playing around with a very basic class, which I have probably really screwed up, but am looking to create an array of the classes. This is just a module for me to learn how to play with some of these tricks. What is happening, is the variables all get passed, and stored, but my output is only the last inputted infomation, not what should be the prior stored information in the array. I believe it has something to do with using the pointers on the strings, but I haven't figured out anything else to do with them yet. I'm still teaching myself all this fun stuff, so bear with the easy questions.
/*
I'm trying to create my own class to store information about a person
in this example, an employee. This is just a test run to be able to
create a class, instantiate an aray of objects based on that class,
and update them as we need to input the record. This is just the first block of a larger scope program.
*/
#using "mscorlib.dll" //ignore the quotes, had to alter to use HTML here
using namespace System;
__gc class NameStorage
{
public:
String* GetName()
{
fullName = String::Copy(String::Concat(lastName,", ", firstName));
return fullName;
}
String* GetCompany()
{
return company;
}
double GetSalary()
{
return salary;
}
void SetFirstName(String* input)
{
firstName = String::Copy(input);
}
void SetLastName(String* input)
{
lastName = String::Copy(input);
}
void SetCompany(String* input)
{
company = String::Copy(input);
}
void SetSalary(double input)
{
salary = input;
}
private:
String *firstName, *lastName, *company, *fullName = "";
double salary = 0;
};
void main()
{
NameStorage *names[] = new NameStorage*[3];
for(int i = 0; i < 3; i++)
{
// Error is coming in that the individual elements of the array are not
// being updated independently.
Console::Write("First Name: ");
names[i]->SetFirstName(Console::ReadLine());
Console::Write("Last Name: ");
names[i]->SetLastName(Console::ReadLine());
Console::Write("Salary: ");
names[i]->SetSalary(Convert::ToDouble(Console::ReadLine()));
Console::WriteLine(names[0]->GetName());
Console::WriteLine(Convert::ToDouble(names[0]->GetSalary()));
Console::WriteLine(names[1]->GetName());
Console::WriteLine(Convert::ToDouble(names[1]->GetSalary()));
Console::WriteLine(names[2]->GetName());
Console::WriteLine(Convert::ToDouble(names[2]->GetSalary()));
}
return;
}
This is an edited version of the code, I think I am missing my initialization of the array elements, but with them, i was getting the same results. Again, thank you for any insight to this, my proffessor is an old FORTRAN COBOL programmer who has never seen any of this stuff, and is no help at all

in your code
void main()<br />
{<br />
NameStorage *names[] = new NameStorage*[3];<br />
you create here an array of pointers not an array of objects
use
void main()<br />
{<br />
NameStorage *names = new NameStorage[3];<br />
and in stead of calling further in your main func
names[i]->Setblabla()
use
names[i].Setblabla()
also you should put your writeline commands outside the for-loop.
Greetings,
Davy

Thanks Davy. I think I've tried this... Now I'm getting a compile error. I'm using Visual Studio .net 2003 by the way.

using namespace System;
__gc class NameStorage //Starting the class definitions

Console::WriteLine(Convert::ToDouble(names[1].GetSalary()));
Console::WriteLine(names[2].GetName());
Console::WriteLine(Convert::ToDouble(names[2].GetSalary()));
}
return;
}
Now I'm getting the following errors:
StringSorter.cpp
StringSorter.cpp(62) : error C2691: 'NameStorage' : invalid type for __gc array element
StringSorter.cpp(62) : error C3149: 'NameStorage' : illegal use of managed type 'NameStorage'; did you forget a '*'?

StringSorter.cpp(68) : error C2228: left of '.SetFirstName' must have class/struct/union type
type is 'NameStorage __gc *'
did you intend to use '->' instead?
Last Error repeats for each reference back to the class.

is there a way to create them programmatically?

My guess is that you are wanting to create an alogrithm that creates a wav file. This will be MUCH harder than making a standard recording due to the number patterns you will need to make in order to get the sound you want. In fact this would be a guessing game that may never produce the intended results. But to answer your question you will first need to create a program that creates the correct file structure. Here is a link to a place that describes this:
http://www.daubnet.com/formats/RIFF.html
Wav files are just a form of riff files (which were originally called iff files and were made by electronics arts for video games). For the ID section you will want to put "wav " and the data will consist of pairs of signed bytes. The byte pairs correspond to the push and pull that the speaker magnet will produce when the file is played.
Good luck

What is the best way to get the size of a block of code? I thought maybe I could treat labels as pointers sticking one at the beggining and on at the end, but my compiler won't let me do it that way. Any other ideas? I think it might take some ASM code to accomplish, but I barely know any. So if anyone happens to know the best approach...

size in what units? LOC? bytes?
if it's LOC you could try something like this neatened up with a few macros:
long foo()
{
long start = __LINE__;
long end = __LINE__;
return end-start;
}
If it's about generated code try generating assembly / machine code listings from your source when you compile for the appropriate files and then counting opcodes and operands
If you can keep you head when all about you
Are losing theirs and blaming it on you;
If you can dream - and not make dreams your master;
If you can think - and not make thoughts your aim;
Yours is the Earth and everything that's in it.

Sorry for not being specific but I meant bytes. Well actually I thought of one way that might work. I could stick the code in a function with a void parameter and return, then I could measure the length from the start to the return. If anyone has a better idea, keep in mind the method used has to work at runtime. I can't believe that no one has developed a standard method of doing this in C since it has to come up at least fairly often.

Erh, why?, what's the use of it?

I also want to know ?
maybe he's confuse and want to use sizeof ?

I think he actually wants to get the op code size of eg.
<code>
void foo()
{
char buffer[] = "A";
printf("%s\r\n", buffer);
}
</code>
Which translates to something like:
<code>
<br><br>
section .data
<span style="color: green">; data aligned on a 4 byte boundary.</span>
buffer db 'A', 0, 0, 0
mxyzptlk db "%s\r\n", 0, 0, 0, 0
section .text
_foo:
<span style="color: green">; Storing general registers for good measure.</span>
pushaw
<span style="color: green">; pushing arguments from right to left.</span>
push dword buffer
push dword mxyzptlk
<br>
<span style="color: green">; calling the extern function.</span>
call _printf
<br>
<span style="color: green">; Cleaning up the stack</span>
add esp, 8
<br>
</code>
which again translates to some mumbo jumbo machinecode
But besides the point that it's very hard to see the value in that information, there is the problem of buffer, and the anonymous string "%s\r\n", being declared in a data segment, and the rest of the code goes in a code segment (well, generally anyway, but the rare exceptions really shouldn't count).

The issue here is self modifying code. In order to pull this off correctly I need to be able to tell the size of a code block so I don't read over it's memory bounds when copying it to another location. Yes I could just figure out the size and declare it as a constant or something, but this would have nasty results if I changed the code that was being copied and forgot to update it's size.

Can anyone help me with this one:
I am tying to write an application that uses separate thread to communicate with the COM port. Everything is working fine but when I try to cancel the communication by using Thread::Abort() my application just freezes. What am I doing wrong?

You should find a manner to cancel any pending IO on the port first, and then signal to your thread to exit. The thread will 'naturally' exit if it leaves the bottom of the function.
Just blowing off the thread will result in several problems - you migth be failing to close the port, you might be leaking memory, etc.

I have been trying to create a splitter pane inside a tab control but have been unsuccesful so far. Can anybody point me to simple example of splitters inside a tab control. I have seen one on code project, but its just too complicated.

Yes I've looked at that..its just too complicated for a begineer like me to understand as yet. Anything else that you might know of?
