Here is the correct method for displaying numerics in English_USA.1252
double dMoney = 0123456789.0123456789;
char szOldCppMoney[MAX_PATH] = {0};
char szNewCppMoney[MAX_PATH] = {0};
sprintf(szOldCppMoney,"%2.2f",dMoney);
LCID lc = MAKELCID(MAKELANGID(LANG_ENGLISH, SUBLANG_ENGLISH_US), SORT_DEFAULT);
GetNumberFormat(lc,0,szOldCppMoney,NULL,szNewCppMoney,ARRAYSIZE(szNewCppMoney));
Output will be: "123,456,789.00"
Best Wishes,

I use ShellExecute() to execute some operations on a ".txt" file. But it just executed a few of them and the others returned an Error.
These operations did not work:
-------------------------------------
1- Properties
2- Delete
3- Rename
.
.
.
Any help?
Thank you masters!

Not all verbs are available to all files and folders.
As the docs state:
"Generally, the actions available from an object's shortcut
menu are available verbs."

Yes I know! But the verbs Rename, Delete and Properties are common to all objectes. Aren't they?
|
|
|
|
|
if you want to delete/rename a file, why don't you use the dedicated API ?

I poked around my registry and tried a bunch of right-clicks
on files of different types...I couldn't find any type that supported
any of those.

The next question is about catching all the SETTEXT message that are sent to a specific window:
I'm trying to hook all the settext messages that are sent to a specific window. The hook works almost perfectly, it intercepts all the settext messages and gets de windows handle stored in the pwp structure. pwp is a CWPRETSTRUCT type structure that contains the information of the SETTEXT hooked message.
The problem is that I can't get the text(caption) send to the window stored in the LPARAM of the settext hooked message (pwp->lParam. I only get garbage).
The idea is to get the text send to the window and save it to a file.
Im using a CallWndRetProc hook.
Here is my code.
LRESULT CALLBACK CallWndRetProc(int nCode, WPARAM wParam, LPARAM lParam)
{
TCHAR *a;
FILE *f1;
if(nCode < 0)
{
return CallNextHookEx(hook, nCode, wParam, lParam);
}
if (nCode == HC_ACTION)
{
CWPRETSTRUCT* pwp = (CWPRETSTRUCT*)lParam;
UINT message = pwp->message;
if (message == WM_SETTEXT)
{
unsigned int whandle = (unsigned int) pwp->hwnd;
// globalvar contains the
// (unsigned int)window's handle I want to catch.
if (whandle == globalvar)
{
LPARAM l = pwp->lParam;
// The problem is on the next line.
// Var a only gets garbage.
a = (TCHAR *) l
f1=fopen("c:\\hook.txt","a+");
fprintf(f1,"%d %s\n", whandle, a);
fclose(f1);
}
}
}
return CallNextHookEx(hook, nCode, wParam, lParam);
}

Could it be possible that the WM_SETTEXT you get has been "POSTED" and the buffer lParam contains a pointer at has been destroyed by the time you get the hook-call?

Hey Friends
I need to start an SDI Application (CFormView Based) Hidden
I do not want it to display main window first & then i cann showwindow(sw_hide)
In VC++ 6.0

....
AddDocTemplate(pDocTemplate);
m_nCmdShow =SW_HIDE;
...
but now in VS 2008
it does not works
Any clue?

|
|
|
|
Don't use the WS_VISIBLE style when creating the window?

Does this page [^] help?

 No! Because it has not introduced any function or algorithm, moreover I think it's only about NTFS!
Any way! Thank you my master, CPallini

The requirements, from the documentation page I posted.
Client Requires Windows Vista, Windows XP, or Windows 2000 Professional.
Server Requires Windows Server 2008, Windows Server 2003, or Windows 2000 Server.

I am working on a project, in C#. Due to security I decided to put some core services in a C DLL. I followed the example in the link:
How to create a DLL library in C and then use it with C#[^]
Now I want to use GetVolumeInformation in this dll. But I don't have any idea how to call it, what include are required etc.
Can anyone provide me help or link.
Thanks

I suppose there is some documentation about [^].

Yes, I already visited that, simple C doesnot have those types. I a, good at C but no experience in Win programming in C
|
|

Well, I bet there is documentation also about those data types [^].

What I am trying to compile is :
#include <stdio.h>
#include <windows.h>
extern "C"
{
__declspec(dllexport) void DisplayHelloFromDLL()
{
char buffVN[512];
char buffSN[512];
char buffMCL[512];
char buffFSN[512];
char *v = "C:\\";
GetVolumeInformation(v, buffVN, 512, buffSN, buffMCL, 0x00000002, buffFSN, 512);
printf ("Serial Number [%s]\n", buffSN);
printf ("Hello from DLL !\n");
}
}
</windows.h></stdio.h>
I am getting error:
error C2664: 'GetVolumeInformationW' : cannot convert parameter 1 from 'char *' to 'LPCWSTR'
