If you are working with MFC you can just create the function of the OnButtonClick using the Wizard (if you are not so self confident to make it by yourself) and then just call the function where you want, when you want.
For example:
in your view/dialog header
public:
enum { IDD = IDD_MY_VIEW};
CButton m_cbTest;
.
.
afx_msg void OnBTestClick();
DECLARE_MESSAGE_MAP()
and in your code file
void CYourView::DoDataExchange(CDataExchange* pDX)
{
CFormView::DoDataExchange(pDX);
DDX_Control(pDX, IDC_BTEST, m_cbTest);
}
BEGIN_MESSAGE_MAP(CYourView, CFormView)
ON_BN_CLICKED(IDC_BTEST, OnBTestClick)
END_MESSAGE_MAP()
and after...
void CYourView::OnBTestClick()
{
your code...
}
and then you can call the OnBTestClick when you want

Hi all,
I'd like to know if it would supose some optimization to use /OPT:WIN98 setting in Visual Studio 2005 / 2008 with XP / Vista as target operating system.
Thanks.

Very less people run Windows 98, so give them a separate build with /OPT:WIN98 linker option.
Otherwise, always build with /OPT:NOWIN98.

Yes I agree, but my question was, if still would be useful to make code 4K aligned? It makes some improvement to run aligned code in XP or Vista? or depends on fat32 / NTFS?
Thanks for replying.

You just lose a few bytes in your executable size, that's it.
|
|
|
|
|
so, there's NO benefit in run time execution?
|
|
|
|

I played with this linker option some time ago, I couldn't see any difference in performance. This may be different for your code, just try it.

You can use
1. Inno Setup
2. Nullsoft installer
3. Installschield
you just google for this and you will get information on that.
Inno Setup/NullSoft installer are freewares and popular.
I hope it helps.

I saw a driver of a cdrom, witch simply transmit IRP_MJ_READ io request to default driver present by the os(calling IofCallDriver). but now, when an io request(IRP_MJ_READ) came, how the driver holds the read data?
I am sure the driver has done some tricks on the read data before returning the data to user application.
Regards,
|
|
|
|
|
If the driver is building its own IRP with IRP_MJ_CREATE before passing it to the lower driver, then that driver has surely supplied a local buffer to the lower driver when calling IoCallDriver. When the IRP returns, then the driver can access the read data through its supplied buffer. Is that what you mean?
|
|
|
|

This is a cdrom driver which was installed for the highest driver over the default one present by the os. In the driver, most of the IRP routine is just simply call IofCallDriver to transmit the IO request to lower driver. my question is that, the driver hasn't constructed a new irp before calling IofCallDriver.
The driver mainly perform decryption ops of the content of the discs. No matter you use a normal user mode app to read discs via ReadFile or just simply use windows Ctrl+C and Ctrl+V to copy and paste any file in the disc, the data read from the disc already is decrypted data.
So, i think the driver might use some special tricks to hold the data read by lower default driver and decrypted it just before the data would be returned to the user mode space. but the problem is, i am not a professional driver programmer but only know little about driver programming.

Hi all
First of all, this is my first time writing here, so please sorry if I do something wrong.
I am developing an application which takes a variable std::string and writes it to an std:fstream file. The string is in Spanish so it may have accents. The problem is that when I try to copy the string to the file, it does not copy the spanish accents. Do you have any idea of what I am doing wrong?
Please help me because this is quite urgent. Thanks in advance.
Regards,
Aitor
The code looks like this:
std::string plainText = receiveString()
printf(plainText.c_str)
std:fstream plainFile;
plainFile.open("c:\\test.txt");
plainFile << plainText << std::endl;
plainFile.close();

How do you determine this? What do the strings in the file look like?
Also, what is the locale (language setting) on your OS?

Hi Michael
First of all, thank you very much for your reply

Sorry Michael. You know that this is my first time writing here and I just sayed that this question was urgent because it is really quite urgent (We have to deliver our application today. Actually, it was for last friday). Anyway, sorry.
Michael Schubert wrote: How do you determine this? What do the strings in the file look like?
It writes different things depending which letter has the accent. For example, instead of writing "qué" it writes "qu,". Instead of writing "pájaro", it writes "p jaro". Instead of writing "comíamos", it writes "com¡amos".

This program (I used VS2005) produces the two identical files os.txt, fp.txt, both containing the string with the accent.
#include <stdio.h>
#include <fstream>
#include <string>
using namespace std;
int main()
{
FILE * fp;
ofstream os;
fp = fopen("fp.txt", "w");
os.open("os.txt", ios::out);
fprintf(fp, "città\n");
os << "città" << endl;
fclose(fp);
os.close();
}

Fixed the formatting of the code snippet, thanks to Rajesh.
