I've been struggling with this for days and as soon as i post i found a solution.
In any case, it seems i've been setting the wrong timer, this fixed the problem:
mySession.SetOption(INTERNET_OPTION_CONNECT_TIMEOUT,50000);
mySession.SetOption(INTERNET_OPTION_CONNECT_RETRIES, 3);
mySession.SetOption(INTERNET_OPTION_CONNECT_TIMEOUT, 50000);
mySession.SetOption(INTERNET_OPTION_DATA_RECEIVE_TIMEOUT,50000);
mySession.SetOption(INTERNET_OPTION_RECEIVE_TIMEOUT,50000);
mySession.SetOption(INTERNET_OPTION_DATA_SEND_TIMEOUT, 50000);
mySession.SetOption(INTERNET_OPTION_SEND_TIMEOUT, 50000);

I Want to convert char array into LPCTSTR ,std::string to LPCTSTR and DWORD to LPCTSTR
can any body help me to solve this.

Try the search box above with "string conversion". This is a task of learning to read code and documentation.

If its UNICODE is defined, the LPCTSTR will expand as const wchar_t*. So you've to convert the char* to wchar_t* by using A2W macro. If its not UNICODE, then LPCTSTR is const char* and you can directly assign it. See the code block.
#ifdef UNICODE
#else
#endif
Member 4620216 wrote: std::string to LPCTSTR
call string.c_str() function.
Member 4620216 wrote: DWORD to LPCTSTR
Since DWORD is unsigned long, _ultot() can be used.

Hello all,
I am facing a critical issue. I have my executable at server side which user downloads. User is able to download. Now i want that application to execute itself rather than forcing user to go to downloaded location and execute it. So how would i accomplish this? Is there any way on server side that run downloaded executable on client machine.?? I mean script or something??
Please help me out. Any help would be greatly appreciated.
Thanks & Regards,
Hemang

How is the download happening? You can execute the downloaded binary automatically, only if your program on the client machine is doing the download. If the user is doing the download manually, then he'll have to execute it.

First Thanks for replying .
ACtually my program is doing download and execition. But for some specific reason it is not working for some of the client. So do not waant to change that client program as it is downloading perfectly and only getting problem in execution of that program
so do not want to force user to manually execute it but somehow execute downloaded exe by itself on client machine either from server or triggering some event while download so it will auto-execute downloaded file from its location
I look forward for further help.
Thanks & Regards,
Hemang

This is vague. What exactly is the 'problem'? I suggest that you try analyzing the log file of your application.

I knew that it would be difficult to explain. You are right that it is also difficult for you to understand where exactl the problem is.
But can you please throw light in some other direction. Suppose i want to execute a particular application after it is downloaded. Is it possible for executable file that is being downloaded to execute itelf after its complete downloading or from server where it is being downloaded, can we do at that side (server) to execute it.
I may be silly asking such question but this kind of question arises when i think of spyware and viruses. Because nobody tell them to execute but they maliciously run after being downloaded.
So please further share your knowledge.
Thanks & Regards,
Hemang
Thankd

An binary will not be able to execute 'itself' after it's been downloaded. You either need a watchdog which will be monitoring the download to execute it upon completion. But as you already say that it is your own application that does the download, it could as well execute the file after download. If there are issues on specific computers, try logging the events from your application and find out what is causing this problem. You can use an external debugger like DebugView[^]to print debug strings (the name is misleading, works on release versions as well) if you wish not to use a log file.

I really thankful to you. I will have look at DebugView. But once again thank you. I am obliged.
Thanks & Regards,

You're most welcome. And I forgot to mention: The API which prints to DebugView is OutputDebugString. Look it up in MSDN.

how to get process start time in vc?
wqewqqeweqwrwerewrwe

Use GetProcessTimes() or Sample Code[^]. Hope this helps and is relevant to your needs.
Somethings seem HARD to do, until we know how to do them.

Will API GetProcessTimes helpful ?

I created a dll file like this :
HHOOK MyHook;
HINSTANCE MyInstance;
LRESULT CALLBACK MyMouseHookProc(int nCode, WPARAM wParam, LPARAM lParam);
extern "C" __declspec(dllexport) void Hook();
extern "C" __declspec(dllexport) void Unhook();
BOOL CMouseHook1App::InitInstance()
{
CWinApp::InitInstance();
MyHook = NULL;
MyInstance = this->m_hInstance;
return TRUE;
}
void Hook()
{
if(MyHook == NULL && MyInstance != NULL )
{
MyHook = SetWindowsHookEx(WH_MOUSE,MyMouseHookProc,MyInstance, 0);
if(MyHook!= NULL)
MessageBox(NULL,_T(" HOOKED "), _T(""),0);
}
else
MessageBox(NULL,L" Not Hooked", L"",0);
}
LRESULT CALLBACK MyMouseHookProc(int nCode, WPARAM wParam, LPARAM lParam)
{
if(nCode <0)
{
CallNextHookEx(MyHook,nCode,wParam,lParam);
return 0;
}
if(wParam == WM_LBUTTONDOWN || wParam == WM_NCLBUTTONDOWN)
{
MessageBox(NULL,_T("OK"),_T("Test"),MB_OK);
PostMessage(hWndApp,WM_LBUTTONDOWN,0,0);
}
return CallNextHookEx(MyHook,nCode,wParam,lParam);
}
But in my app, when I use the function Hook(), it doesn't work at all. Did I do anything wrong? Someone plz help me

You need to declare the HHOOK MyHook; in a shared data section.
So you need to first create a data section, declare the HHOOK in that data section and then make that section shared.

I am getting set hexa decimal values as I/P from user into a CString.
I am tokenizing this and get separate hexa values in another CString.
I want to convert this single hexa value in CString to unsigned char.
How to do this?
Or can I get input in unsigned char itself and tokenize is possible?
Thanks,
Suman

Use strtoul().

You already have the IP in number form so it should be easier for you to split it out byte by byte. Why to use CString in between?
Or if you are forced to do so then you can use functions like StringToAddress and AddressToString for converting ipaddress byte array from and to a string. Though not sure whether this will work with IP address in hex form.
Hope this helps!

Hi Nibu thomas,
Thanks for the help,
The input is some MIDI command like "0x90 0x00 0x01"
The separator can be space or comma.
If I get the above command, how to assign them to unsigned char array except separators if possible without CString?
I will try strtol() once which David crow recommended.
Thanks,
Suman

Well then you've got to convert it to byte form!

Suppose there are three classes Class A, Class B and Class C.
Class A
{
public:
//one virtual function
}
Class B
{
public:
//one virtual function
}
Class C:virtual public A, virtual public B
{
}
How many v-tables Class C has?
