Hi,
Thanks for the information.I am able to write from process1 and read from process2.
But i want read and write simultaneously(even write from process2 and read from process1).
Ex:
1)Write some data from process1 and read the same data from process2.
same time
2)Write some other data from process2 and read the same data from process1.
Thanks
Sharan

Hello everybody,
i am having a combobox (created manually using resource tool) in a dialog box.
during runtime, i need to increase the width of the combobox window (not the drop down width). option is given for setting drop down width only. but i need to increase (or decrease) the width of the originally created combobox.
Is that possible?
i am using vs 2008 and win32 API.
Thanks in advance.
Regards
A. Gopinath.
Never mind. tried with MoveWindow(), its working fine.
Thanks again.

Try with using CWnd::SetWindowPos[^] or CWnd::MoveWindow[^].

Hi,
I am currently writing a unicode MFC application in VS 8, and I want to get my commandline arguments. So I use ::__argv and ::__argc, but while the argument count is always determined correctly, ::__argvs always NULL in my Apps InitInstance-method.
Why? m_lpCmdLine however works, but I'd rather want to use __argv. Any hint why this parameter is always NULL?

|

did u try __targv, i am not sure. just give a try.
If u can Dream... U can do it

Generally speaking, installation or uninstall for LSP need a reboot. Is that possible not reboot after installation or uninstall in server edition windows, like 2003, 2008? If so, how could i do it, Any link or tip will be appreciated.

I'm missing something here. I can write a single value to a ads key, but I can't write a multistring value. I've been googling for hours, but can't really find anything on the subject
LPWSTR pszMimeMap[] = {
L".application, application/x-ms-application",
L".deploy, application/octet-stream",
L".deploy,application/octet-stream",
L".flv, video/x-flv",
L".manifest, application/-x-ms-manifest",
L".msp, application/octet-stream",
L".msu, application/octet-stream"};
dwNumber = sizeof(pszMimeMap)/sizeof(LPWSTR);
hr = ADsBuildVarArrayStr(pszMimeMap, dwNumber, &var);
hr = pADs->PutEx(ADS_PROPERTY_UPDATE, CComBSTR("MimeMap"), var);
VariantClear(&var);
I get the -214 something error in Hresult instead of the S_OK.

Good Call, I added the line, must of missed it.
Well after hours of testing, I can write the ScriptMaps, but not the MimeMap, I get some -214 error.
hr = pADs->PutEx(ADS_PROPERTY_UPDATE, CComBSTR("MimeMap"), var);
I can write this ScriptMaps key as a multi-string, and it works fine.
};
LPWSTR pszScriptMaps[] =
{
L".asp,C:\\WINDOWS\\system32\\inetsrv\\asp.dll,5,GET,HEAD,POST,TRACE",
L".cer,C:\\WINDOWS\\system32\\inetsrv\\asp.dll,5,GET,HEAD,POST,TRACE",
};
dwNumber = sizeof(pszScriptMaps)/sizeof(LPWSTR);
VariantInit(&var);
hr = ADsBuildVarArrayStr(pszScriptMaps, dwNumber, &var);
if (SUCCEEDED(hr)) {
hr = pADs->PutEx(ADS_PROPERTY_UPDATE, CComBSTR("ScriptMaps"), var);
}
VariantClear(&var);

Hello all,
I'm looking on the way that i could create my own namepsace and use it under C++.
i wrote a .h file
#ifndef FOO_H
#define FOO_H
namespace FOO
{
int add (int a , int b);
}
#endif//FOO_H
and a cxx file
#include "Foo.h"
namespace FOO
{
int add (int a , int b)
{
return (a+b);
}
}
And in the main prog (test.cxx) i did as shown below
#include <iostream>
#include "Foo.h"
using namespace FOO;
int main(int argc, char **argv)
{
std::cout << add(5, 6) << std::endl ;
return 0;
}
when i compile the prog it mentions no problems but when i try to execute it it said
undefined reference to `FOO::add(int, int)'
i look on the net but still having that issue.
how could i make it correct ?
thank you.

Ok i think that i resolved it by changing the .h file like this
#ifndef FOO_H
#define FOO_H
namespace Foo
{
int add (int a , int b)
{
return (a+b);
}
}
#endif//FOO_H
So that mean's that :
1: when using namespace we can only use header files.
or
2: i ve an error somewhere in my previous files.
could someone help me with that ? i get
"The Ultimate Limit Is Only Your Imagination."

What you did in your first post is correct.
The problem you run into is a LINKER problem, not compiler (if you are unsure about the difference, study a while how compile and linking process works)
Your "program" is actually made by two sources (main.cxx and foo.cxx): you have to compile them both, and link them together to produce a final executable. both the files must be inside your "project" configuration.
By placing the function definition in the header you solved the problem because now everything you need in known to main.cxx (that's probably the only file you compiled) But if you compile bot files now you will get a "symbol defined more than once" linked error.
So either:
- use separate files, but compile them all
- use only a single "cxx" and define everything the the header. But -in this second case- declare the functions you will define at header level as "inline" (inline int add(int a, int b) { ... } ) to avoid multiple definitions in case of multiple compilations.

You are all reasons,
I compiled the first post files with VS and in the project settings i included the Foo.cxx file and all worked fine.
I used Geany under ubuntu and in the console i wrote gcc test.cxx Foo.cxx -o Test.o
and then some warnings were releaved.
i think, as you said, i need to go backward and read more about linking files in C++
thank you for your help.

This is not correct, the output should be your executable file Test (note executables do not have .o extension). You should then be able to run your program by typing Test at the command prompt. Take a look at the man pages for gcc for more information on compile and link options.

I use method, AttachFile of class CMimeMessage to add a file to mail
CMimeMessage msg;
...
msg.AttachFile(_T("d:\1.txt"), _T("1.txt"));
then use CSMTPConnection::SendMessage(msg) to send this mail, but I find that this mail does not send to my mail box.
The mail account is no problem, because a blank mail can be sent.
I do not know how to use CMimeMessage to send a file ?

This is a C console application in VS2008.
I've got a script language similar to C but the host application has very few debug facilites. With a little modification I can convert the script to plain C and run it in a wrapper in a console app. In the script all variables must start $. If I try to watch a variable $x the watch window says:
$x CXX0017: Error: symbol "x" not found
If I #define $x x it finds it OK but I have to redefine all my variables this way in order to watch them.
Does anyone know why VS doesn't like the leading $ and whether it's possible to configure it to accept it as a normal symbol?
Thanks

This looks like a mistake on Microsoft's part. Even though they allow a variable to start with a dollar sign, the debugger does not seem to recognise it.
|
|
|
|
|
If that is an error... interesting catch...
It wouldn't be the first time one part of the MS IDE doesn't match what another part does.
|

Having never used the dollar sign (a Microsoft extension) for identifier names I thought it worth a try.

Hi,
In my VC++ project I have to draw 2D graphs (X,Y). I would like to know which component I have to use for the same.
Also, The graphs should be rendered at run time continuously for the input values, same like display of ECG machine.
I'm using VS 2010 Express edition..
Hope you have understood my issue, kindly reply,
Regards,
Vijay.

Cedric had an article on that. I'm not sure if that would suit your needs, but take a look at it: High-speed Charting Control[^]
